At this time, the elastically arranged push plate is no longer limited, and under the action of the fourth return spring, it squeezes the gas inside the air storage bin, so that the gas inside the air storage bin is discharged into the first airbag through the first exhaust pipe. The first airbag expands and pushes the trigger block to move downward. When the trigger block moves downward, it squeezes the uppermost first abutting rod. The first abutting rod moves downward and is inserted into the uppermost second through groove. At the same time, it squeezes the second abutting rod inside the second through groove, and so on, so that each adjusting rod is in contact with the workpiece, realizing the clamping of workpieces with different shapes;

[0038] 3. A sliding block is arranged on the clamping rod, and a first pull rope is arranged between the sliding block and each jack. By pulling the sliding block, the reset of the jack is realized, thereby releasing the limit fixation of the adjusting rod;

[0039] 6. A grinding frame is arranged on the processing table, and a brush is arranged inside the grinding frame. After processing, the workpiece is moved into the grinding frame through the cooperation of the electric telescopic rod and the clamping ring. During the movement, the brush can clean the waste chips adhering to the surface of the grinding frame. BRIEF DESCRIPTION OF THE DRAWINGS
