[0025] The main function of the base 19 is that it is heavy, so that the workbench 1 remains stable as a whole, while providing a supporting effect.

[0026] There are four buckles 5 , which are all located above the limiting plate 4 , and the four buckles 5 have a certain elasticity.

[0027] The main function of the four buckles 5 is to clamp the gear 6 above the limit plate 4, so as to prevent the gear 6 from falling off during processing and affecting the processing efficiency.
