The plate body support portion 801 is located at the bottom of the bearing plate body 701 and the connecting rod body 702 is penetrated through the plate body support portion 801. The sleeve portion 802 is rotatably matched with the side of the plate body support portion 801 away from the bearing plate body 701. The connecting rod body 702 is penetrated through the sleeve portion 802 and is threadedly matched with the sleeve portion 802. When the sleeve portion 802 is rotated to make the plate body support portion 801 contact the bearing plate body 701, the support seat 8 can achieve stable support for the bearing plate body 701.

[0042] Reference Figure 4In order to further ensure the stability of the position of the bearing plate 701 when it is loaded, the plate support part 801 is fixed to the bearing plate 701 by screws. In order to facilitate the rapid and stable movement of the plate support part 801 to the position where it is fixed with the bearing plate 701, a sliding limit part 9 is fixedly connected to the inner side of the plate support part 801. A sliding limit groove 10 extending along the length direction of the connecting rod body 702 is provided on the outer peripheral surface of the connecting rod body 702.
