[0012] Further, the upper end of the inboard of advancing rod is wound with reset spring, and the bottom of reset spring is connected with the top of sealing element.

[0013] Compared with prior art, the utility model has the advantages that:

[0014] 1. When the threaded rod rotates, it can drive the externally set movable block to move in the opposite direction, so that the movable block can drive the clamping plate and clamp and fix the servo motor body. The output end of the pneumatic telescopic rod controls the up and down movement of the fixing frame. The data detection component set inside the fixing frame can collect data on the temperature, noise and vibration amplitude of the servo motor body. Finally, the data is displayed on the display set outside the mounting frame, which facilitates the comparison of motor performance data.

[0015] Furthermore, as the movable block is moved, it simultaneously drives the push plate and slider below to move. The slider slides inside the groove, which fixes the angle of the movable block during movement, preventing the movable block from deflecting due to the rotation of the threaded rod, thus making the movable block more stable during movement.

[0016] Furthermore, the clamping plate has a C-shaped cross-section, which allows the inner side of the clamping plate to better fit and limit the movement of the outer side of the servo motor body. This enables the servo motor body to clamp and fix clamping plates of different shapes and sizes, increasing the stability of the servo motor body when clamped.

[0017] 2. When the movable block moves the push plate, it squeezes the pressing plate. When the pressing plate is squeezed, the gas inside is delivered to the inside of the elastic layer through the hose. The inner side of the elastic layer is thus inflated and better fits against the outer side of the servo motor body, thereby enhancing the stability of the servo motor body during performance testing and reducing the amplitude of vibration.

[0018] Furthermore, by pressing the pressing block, the push rod at the bottom of the pressing block moves downward inside the fixed rod. The push rod then pushes the piston downward, and the air inside the suction cup is expelled due to the movement of the piston. At the same time, the pressing block automatically resets due to the elastic force of the reset spring. When the pressing block resets, the push rod moves upward, and the push rod drives the piston to move upward inside the fixed rod. The reset of the piston will make the inside of the suction cup a vacuum state, thereby fixing the overall position of the device. Attached Figure Description
