The multiple hydraulic cylinders 2 are located directly above the base 1, and a top plate 3 is fixedly connected to the side wall of each hydraulic cylinder 2. The two adjusting devices 4 are disposed on the surface of the base 1. Each adjusting device 4 includes a moving block 41, the surface of which is slidably connected to the inner wall of the base 1. A fixing block 42 is fixedly connected to the bottom end of the moving block 41, and a positioning pin 43 is threadedly connected to the inner wall of the base 1. A connecting plate 44 is fixedly connected to the upper surface of block 41, and the upper surface of the connecting plate 44 is fixedly connected to the bottom end of the hydraulic cylinder 2. During operation, the moving block 41 is pushed to move the moving block 41 on the inner wall of the base 1. The moving block 41 drives the connecting plate 44 and the fixed block 42 to move. The connecting plate 44 drives the hydraulic cylinder 2 to move. After the hydraulic cylinder 2 moves to the appropriate position, the positioning pin 43 is rotated to the fixed block 42 and the inner wall of the base 1. By setting the moving block 41, the fixed block 42, the positioning pin 43 and the connecting plate 44, the position of the hydraulic cylinder 2 can be easily adjusted.

[0024] The base 1 has a groove 45 on its surface near the multiple movable blocks 41. The surface of the movable block 41 is slidably connected to the inner wall of the groove 45 of the base 1. During operation, the movable block 41 slides on the inner wall of the groove 45. The groove 45 facilitates the movement of the movable block 41.

[0025] The base 1 has multiple positioning holes 46 on its side wall. The surface of the positioning pin 43 is threadedly connected to the inner wall of the positioning hole 46 of the base 1. During operation, the positioning pin 43 rotates to the inner wall of the positioning hole 46, and the positioning hole 46 is designed to accommodate the positioning pin 43.

[0026] A pull block 47 is fixedly connected to the side wall of the movable block 41. When working, the pull block 47 is held and pushed, and the pull block 47 will drive the movable block 41 to move. The position of the movable block 41 can be easily adjusted by setting the pull block 47.

[0027] The bottom end of the connecting plate 44 has two storage slots 48. Multiple support wheels 49 are rotatably connected to the inner surface of the storage slots 48 of the connecting plate 44. The support wheels 49 are located on the upper surface of the base 1. During operation, the connecting plate 44 drives the support wheels 49 in the storage slots 48 to roll on the surface of the base 1. The support wheels 49 can support the connecting plate 44.

[0028] The base 1 has a storage device 5 on its surface. The storage device 5 includes a storage plate 51, which is inserted into the inner surface of the groove 45 of the base 1. A handle 52 is fixedly connected to the side wall of the storage plate 51. Two inclined surfaces 53 are formed on the surface of the storage plate 51. When working, the handle 52 is held and pushed, which moves the storage plate 51. The storage plate 51 is inserted into the inner wall of the groove 45. When debris is splashed, the debris will fall into the inner wall of the storage plate 51. At the same time, the inclined surfaces 53 can also facilitate the entry of debris from the edge into the inner surface of the storage plate 51. By setting the storage plate 51, handle 52 and inclined surfaces 53, debris can be collected conveniently.

[0029] Support blocks 54 are fixedly connected to both sides of the base 1 near the storage plate 51. Limit pins 55 are threadedly connected to the inner walls of the two support blocks 54 and the inner wall of the handle 52.

The setting of the limit pins 55 and the support blocks 54 can limit the position of the handle 52.

[0030] Working principle: When hydraulic equipment is needed to fix the workpiece, pulling the pull block 47 causes the moving block 41, the fixed block 42, and the connecting plate 44 to move. The moving block 41 slides on the inner wall of the slide groove 45. When the connecting plate 44 moves, it drives the hydraulic cylinder 2 to move. After the hydraulic cylinder 2 moves to the appropriate position, it rotates the positioning pin 43 to the inner wall of the fixed block 42 and the positioning hole 46. When the connecting plate 44 moves, it also drives the support wheel 49 to roll on the surface of the base 1. When the support wheel 49 rotates, it rotates on the inner wall of the receiving groove 48. Then, the hydraulic cylinder 2 is activated to drive the top plate 3 to move. The top plate 3 presses against the workpiece. By setting the entire assembly... The device allows for easy adjustment of the position of the hydraulic cylinder 2, thereby increasing its adaptability to different workpieces and reducing the instability of the workpiece. During processing, the grip handle 52 is pushed, which in turn moves the collection plate 51. The collection plate 51 is inserted into the inner wall of the slide groove 45. After the collection plate 51 moves to the appropriate position, the limit pin 55 is rotated to the inner wall of the two support blocks 54 and the inner wall of the grip handle 52. When debris is splashed, it will fall into the collection plate 51. Some of the debris that falls to the edge will be guided into the collection plate 51 by the inclined surface 53. By setting the entire device, it is easy to collect debris and reduce the tediousness of cleaning debris.
