[0018] The effect achieved by the above components is that when the end of the connecting rod away from the connecting strip approaches the rubber ring, the protrusion is pressed on the rubber ring, causing the rubber to be squeezed and deformed, thereby effectively limiting the connecting rod to one side of the limiting plate.

[0019] Preferably, a bolt is inserted through a thread on one side of the connecting strip, and the bolt is rotatably inserted on one side of the disc.

[0020] The effect achieved by the above components is: manually rotating the bolt drives the connecting bar to move in a direction close to the disc.
