The old bike bell
The old cycle bell is enough to call it pride in the ringside, and when the bell bell bell bell is pressed, the bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell bell be what's not shown in the figure is the top bell bell, and with this part we'll be able to assemble the full bell. And when it is placed on it, the spin-coated bell will hit the bell, and it will make the sound of the bell。
Bike bell structure profile
The cycle bell consists of three parallel axes of direct rods and a simple roller. When the swinging apparatus moves, the gear turns between the gears, and the bells click, making a sound。
02 mechanical keyboard
A mechanical keyboard is an upgraded evolution keyboard, which is distinguished from a popular membrane keyboard, which consists of a complete circuit board, some with a steel plate, with a welding key switch (axis). The removal of the cap shows that each key has a separate switch (i. E. A switch) to control the closure, which is also known as the "axis," the axle is a bone and the cap is a flesh and blood。
The majority of the mechanical keyboards currently sold on the market use the mx axes of the firm, which are common in the series of tea axles, blue axles, black axes and four red axles, as well as rare or inactive axes such as white axles, grey axles and green axles。
Tea axis: the sense of the paragraph is much weaker than that of the green axis, while the contrast of the black axis, not the straight-up, triggers 2 mm. It was compared to the fall of cherry, which combined the characteristics of the green axis with the black axis, which was easily accepted by the general public, and the colour of the tea axis was closer to that of the harvest in the autumn。
Black axis: the least visible sense of the paragraph, the smallest sound, in sharp contrast to the formation of the blue axis, which can be triggered by a 1. 5 mm down. It was compared to the summer of cherry, and whether you want to get a fast or relaxing input, the black axle can handle it, and the typing game fits, but because the trigger is short and the pressure grams are larger, it's a good show. The mechanized black axle keyboard has a service life of up to 50 million times (the other 20 million times)。
Red axis: similar to the black axis. However, the number of pressure grams is smaller than the black axis, starting 35, ending 60 (from 40). It's a new axis from '08. Hands are lighter. Clicking without a sense of paragraph, up and down, triggering the key range is also 2. 0 mm, easier to hit and better balanced with the use of typing. There are only black and white products at the cherry plant。
Aggregation: the strongest paragraph, crick's loudest voice, the strongest mechanical sense, the most representative axis of the mechanical keyboard, which requires a 2. 4 mm pressure to trigger, and a full typing rhythm, but with a larger voice and a loud noise, the pressureg count is 60 g. Some refer to it as the spring of cherry, and the smooth and clear paragraphs are as smooth as spring。
White axis: the sense of the paragraph is stronger than that of the tea axis and, because the number of pressure grams is larger, it is more laborious to press and requires a 2. 2 mm trigger, which, if the finger is smaller, is easily exhausting. It was compared to the winter of cherry, not only because it was a white axis, but because the pressure grams were larger than the black axis, there was a sense of falling into the snow and it was difficult to describe。
Mechanical keyboard advantages:
The most important thing is the axle. The mechanical keyboard has a longer life than the normal membrane keyboard
When the mechanical keyboard is used for a long time, there's little change in the key handle, and the film is not possible
The keypads have different keypads, different keypads, and a single film
Mechanical keyboards can be free of more than six keys, some mechanical keyboards can be non-conflicted, and fewer membrane keyboards above six keys
You can change your own key hat
Mechanized keyboard disadvantage:
High sales prices because of higher costs, most of the market is $400-800, and thousands more are not surprising
Although the keyboard has a long life, it is less waterproof and needs to be used more carefully
03 ripples
Wire strippers
Wire stripping clamps make the process very easy. When holding the handle of the pliers, the reinforced body on the left of the plier tightens the wire, and the cutter on the right uses the shallow plastic skin without touching the metal inside. Hold the handle tighter, and the left pulls the wire, which still has an insulation, to the left, and the right pulls out the broken “cover”。
Fibre strippers
Skin operations
Head protection
Protection packages distinguish different colours
04 spray bottle
This is not considered to be a water sprayer, but the mechanical principle of spray bottles is one of the outstanding applications of a one-way valve. When we untie the trigger, the air enters the bottle, pushes the flow along the straw deep below the bottle and enters a chamber. When we pull the trigger, the water from the chamber comes out。
05 transformer
The gear transformer is a vehicle used to change the speed and rectangular from the engine, and it is fixed or slotting to change the output axis and input the axle transfer ratio, also known as the transformer box. It is divided into manual, automatic, and manual gear transformers consist mainly of gears and axes, which produce a variation rectangular through a combination of gears, while automatic gear transformers at consists of liquid transformers, planetary gears and hydraulic manipulation systems, which reach the rate changer rectangulars by means of fluid transfer and gear combinations。
A manual transformer is called a manual transformer (utilized mt) or a mechanical transformer, i. E. A gear transformer (commonly known as “blocking”) must be moved by hand in order to change the gearing position within the gear transformer, change the transmission ratio, and thus achieve the purpose of the transformer。
Its simple structure, reliable performance, low manufacturing and maintenance costs, as well as high transmission efficiency (theoretically more fuel-efficient), and the fact that it is purely mechanical in nature, is fast-reactive and more directly representative of the wishes of the driver, make it more fun to drive. It is, however, cumbersome compared to the automatic transformer, and it is irremediably unrecoverable for the obvious disadvantage when the block switch is made。
The function of the transformer
Change motion ratio
(b) to enable cars to retrogressive when engine rotation remains unchanged
Use a space block to interrupt power transmission so that the engine can start, glide, and make it easier for the transformer to change gear or to perform power output。
