In the slot 36, the top of the sliding post 6 is fixedly welded with a third spring, and the top of the third spring is fixedly welded on the inner wall of the top side of the chute 5, and the first telescopic shaft 4 continues to move downward so that the sliding post 6 is fixed on the inner wall of the chute. 5, the third spring is elastically deformed, and the sliding column 6 drives the limiting block 37 to slide in the limiting groove 36.

In the present invention, a second telescopic hydraulic cylinder 38 is fixedly mounted on the top side of the workbench 1, and a second telescopic shaft 39 is fixedly mounted on the output end of the second telescopic hydraulic cylinder 38, and a fixed block is fixedly welded on the top of the second telescopic shaft 39. 40, the fixed block 40 corresponds to the position of the extrusion plate 15, put the rocker arm on the fixed block 40, start the second telescopic hydraulic cylinder 38, and the output end of the second telescopic hydraulic cylinder 38 stretches to drive the second telescopic shaft 39 Moving, the second telescopic shaft 39 moves to drive the fixed block 40 to move and then drives the position of the rocker arm to change.

In the present invention, when it is necessary to clamp, the rocker arm is placed on the fixed block 40, the second telescopic hydraulic cylinder 38 is activated, and the output end of the second telescopic hydraulic cylinder 38 stretches to drive the second telescopic shaft 39 to move, and the second telescopic The movement of the shaft 39 drives the fixed block 40 to move and then changes the position of the rocker arm. When it reaches a suitable position, the first telescopic hydraulic cylinder 3 is activated, and the output shaft of the first telescopic hydraulic cylinder 3 is pulled to drive the first telescopic shaft 4 to move. The movement of a telescopic shaft 4 drives the third spring, the sliding column 6, the pushing column 7, the moving rod 34, the mounting rod 13, the mounting block 14 and the extruding plate 15 to move downward, when the extruding plate 15 positioned in the vertical direction moves downward When moving against the rocker arm, the extrusion plate 15 in the vertical direction cannot move at this time, the first telescopic shaft 4 continues to move downward to make the sliding column 6 slide in the chute 5, the third spring elastically deforms, and the sliding column 6 Sliding drives the stop block 37 to slide in the stop slot 36, while the movement of the first telescopic shaft 4 drives the two push rods 10 to rotate, and the rotation of the two push rods 10 drives the two sliders 9 respectively on the two U-shaped rods 8 Sliding up, the sliding of the two sliders 9 drives the rotation of the two connecting rods 11 respectively, the rotation of the two connecting rods 11 drives the rotation of the two rotating rods 12 respectively, the rotation of the two rotating rods 12 respectively drives the rotation of the two movable rods 35, and the rotation of the two connecting rods 12 The rotation of the movable rod 35 drives the two mounting rods 13 to slide respectively on the two moving rods 34, and the sliding of the two mounting rods 13 respectively drives the two mounting blocks 14 and the two extrusion plates 15 positioned in the horizontal direction to approach each other. When a squeeze plate 15 positioned in the horizontal direction presses the rocker arm, the fixation is completed at this time, and the first telescopic hydraulic cylinder 3 can be closed. When the squeeze plate 15 wears and needs to be replaced during long-term use, the squeeze plate 15 The mounting column 16 on the top moves in alignment with the mounting groove 17, and the mounting column 16 moves and squeezes the two wedge-shaped blocks 42 to keep them away from each other. The second springs are all elastically deformed, and the two L-shaped limit rods 21 are separated from each other to drive the two movable columns 23 to move on the two movable holes 41 respectively, and the movement of the two movable columns 23 drives the two L-shaped rotating rods 22 respectively. Rotation, the rotation of the two L-shaped rotating rods 22 respectively drives the rotation of the two displacement rods 24, the rotation of the two displacement rods 24 respectively drives the two ejector rods 25 to approach each other, and the two ejector rods 25 approach each other to drive the two top plates 27 to approach each other At the same time, one of the top plates 27 rotates to drive the drive rod 29 to rotate, and the drive rod 29 rotates to drive the L-shaped baffle plate 28 to slide on the limit column 19, and the L-shaped baffle plate 28 and the L-shaped clamping rod 31 are slowly separated. 16 is completely moved into the mounting groove 17, the slot 32 corresponds to the position of the L-shaped lever 31, and the L-shaped baffle plate 28 is just separated from the L-shaped lever 31. Since the first spring is in a stretched state, the Under the reaction force of the first spring, the L-shaped clamping rod 31 is moved into the clamping groove 32. At this time, the installation is completed. When it needs to be disassembled and replaced, the L-shaped clamping rod 31 is pulled to move out of the clamping groove 32, and the extrusion plate 15 can be moved. replace.
