It is ensured that when the clamping notches and the clamping blocks provided on the semi-annular anti-sponge plates are aligned with each other, the clamping blocks can be reset with the assistance of the reset spring, thereby limiting the semi-annular anti-sponge plates, so that it can be ensured that when vibration occurs, the semi-annular anti-sponge plates will not move, so that sand can be well prevented from entering the interior and causing damage to the joint bearing.
[0011] Compared with the prior art, the utility model has the following beneficial effects:
[0012] The utility model connects the semi-annular anti-sponge plate and the rotating mechanism in the first notch. When the connection is completed, the semi-annular anti-sponge plate can be rotated by rotating the self-locking rotating handle, so that the semi-annular anti-sponge plate can enter the second notch, so that the clamping block can be squeezed into the inner cavity of the rectangular notch.
