[0016] (2) In the present invention, the support plate moves downward by moving the support rod downward, and the support plate moves downward to press the top of the turntable to prevent the turntable from tilting. The pressure of the support plate avoids the error caused by the turntable tilting, thereby ensuring accurate docking during assembly and reducing corrections or adjustments during assembly. The load-bearing plate rotates due to the reaction force of the turntable being squeezed, and the rotation of the load-bearing plate cooperates with the spring to assist in fixing the side of the turntable. By applying a uniform squeezing force to the side of the turntable, the turntable can be prevented from shifting sideways during interference fit, further helping to maintain accuracy during assembly.

[0017] (3) In this invention, the limit rod moves downward to disengage from the protective groove and release the limit on the button. The button can be pressed manually only after the limit on the button is released. The button is pressed to drive the hydraulic equipment to operate. If assembly is performed before the turntable is stable, it will cause inaccurate positioning or uneven interference force, thereby affecting the assembly accuracy. By detecting that the turntable is clamped stably before performing the assembly operation, the assembly process can be smoother, thereby reducing the possibility of damage to parts.
