and in the process of overturning the working plate 2, the round block 14 rotates, the limiting groove 141 moves along with the round block, the edge of the notch of the limiting groove 141 is abutted against the guide surface 45, the abutting force forces the limiting rod 41 to reversely slide for a short distance again, and because the limiting rod 41 is subjected to the elastic force of the first spring 44, the end part of the limiting rod 41 is continuously abutted against the outer peripheral surface of the round block 14, namely when each limiting groove 141 passes through the limiting rod 41, the round block 14 is subjected to the spring force from the first spring 44 once, and the force forms a damping force when the round block 14 rotates, so that the working plate 2 has a rotation damping effect in the process of overturning an angle adjustment angle, and the phenomenon that the mouse key on the working plate 2 is displaced due to too fast overturning speed is reduced.
Example 2: as shown in fig. 7, the difference from embodiment 1 is that the protrusion 46 is configured as a ring structure around the outer periphery of the sliding rod 4, one end of the first spring 44 abuts against the end of the limiting rod 41 away from the round block 14, and the other end of the first spring 44 abuts against the end face of the protrusion 46 facing the limiting rod 41.
Two ends of the first spring respectively abut against the limiting rod and the protrusion, and the sliding rod is forced to reversely slide on the basis of the original effect of the first spring (the limiting rod is forced to be tightly inserted into the limiting groove and the damping force is provided when the round block rotates), so that the pedal has the tendency of rotating and resetting to the initial position; when people lie on the pedal rotating in the forward direction, namely the feet of people swing, the pedal has a certain resetting trend in the swinging process, the resetting trend enables the pedal to have certain damping in the forward rotating process, the damping can improve the safety of the feet when swinging, and meanwhile, the pedal can be rotated to be reset to an initial state (namely, the first connecting rod is in a vertical state as far as possible) through the elastic force of the first spring after losing the control of the feet.
The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
