The first rotation control mechanism comprises a cam, a disc spring 43 and a friction plate 44; the cam comprises a first cam 41 and a second cam 42 which are matched with each other, a disc spring 43 is provided with a plurality of pieces, the first cam 41 and the second cam 42, the disc spring 43 and a friction sheet 44 are sleeved on a first section of shaft 31, the second connecting structure 2 is provided with a limiting position 21 formed by bending, the first section of shaft 31 penetrates through the limiting position 21, one side of the first rotating control structure is limited by the limiting position 21, and the other side of the first rotating control structure is locked by a gasket 45 and a nut 46 in threaded connection with the first section of shaft 31. The first cam 41 is connected with the first-stage shaft 31 in a sliding manner through the matching of the flat hole and the flat position, rotates synchronously with the first-stage shaft 31, but can slide relative to the first-stage shaft 31, and the second cam 42 is connected with the limiting part 21 of the second connecting structure through a pin 421 arranged on the outer side of the second cam, is limited to be provided with a hole 22 matched with the pin 421, and can rotate relative to the first-stage shaft 31. The friction plate 44 is connected to the first-stage shaft 31 for synchronous rotation by engagement of the flat hole and the flat position, and frictionally engages with the second cam 42 under the pressure of the disc spring 43 to provide rotational resistance.
The first rotation control structure at least provides a prompt matching of rotating to a position-in angle; the prompting matching can be formed by matching the salient points and the grooves in the first cam 41 and the second cam 42, when the salient points are rotated to enter the grooves, the disc spring sheets 43 can be suddenly deformed, and the friction resistance between the friction plates 44 and the second cam 42 is suddenly changed to generate sudden change, so that the sudden change is generated, and the prompting function is realized.
