[0026] The working assembly includes a first hydraulic press 2, a push column 3 is fixedly connected to the inner wall of the first hydraulic press 2, one end of the push column 3 is fixedly connected to a connecting frame 4, the inner wall of the connecting frame 4 is rotatably connected to a first connecting column 5, and the outer wall of the first connecting column 5 is fixedly connected to a first connecting block 6;

[0027] The clamping assembly includes a second connecting column 7, the inner wall of the first connecting block 6 is fixedly connected to the second connecting column 7, the inner wall of the second connecting column 7 is rotatably connected to a fixing frame 8, the outer wall of the fixing frame 8 is slidably connected to a fixing block 9, the outer wall of the fixing block 9 is fixedly connected to a handle 10, the inner wall of the fixing frame 8 is slidably connected to a first sliding shaft 11, the inner wall of the first sliding shaft 11 is fixedly connected to a lifting platform 24, the inner wall of the fixing frame 8 is rotatably connected to a gear column 12, the outer wall of the gear column 12 is meshingly connected to a rack 13, the inner wall of the rack 13 is slidably connected to a second sliding shaft 14, and the outer wall of the second sliding shaft 14 is fixedly connected to the lifting platform 24.

[0028] Among them, Figure 3 As shown, the lifting platform 24 is provided with a groove that matches the connecting frame 4. The lifting platform 24 forms a sliding structure with the connecting frame 4 through the pushing column 3, which is beneficial for directly driving the clamping structure to clamp after the first hydraulic press 2 works, and can quickly achieve fixation.

[0029] Among them, Figure 3 As shown, the fixing frame 8 is provided with a sliding groove which matches the first sliding shaft 11. The fixing frame 8 forms a sliding structure with the first sliding shaft 11 through the first connecting block 6, which is conducive to the sliding of the fixing frame 8 along the fixed axis, facilitating clamping while ensuring its stability.

[0030] Among them, Figure 4 As shown, the gear column 12 fits tightly with the rack 13, and the gear column 12 forms a meshing structure with the rack 13 through the first sliding shaft 11, which is beneficial to the lifting and lowering of the fixed block 9, so that it can adapt to objects of different heights and fix them, while preventing the excessive height from affecting high-altitude operations.

[0031] Example 2

[0032] like Figure 1 , Figure 2 and Figure 4 As shown, this embodiment further illustrates Example 1, the outer wall of the lifting platform 24 is fixedly connected to the fence 15, the outer wall of the fence 15 is fixedly connected to the third connecting column 16, the outer wall of the third connecting column 16 is rotatably connected to the block 17, the outer wall of the block 17 is fixedly connected to the spring 18, a second connecting block 19 is arranged on the outside of the fence 15, the outer wall of the fence 15 is rotatably connected to the sliding block 20, the outer wall of the fence 15 is fixedly connected to the fourth connecting column 21, the outer wall of the fourth connecting column 21 is rotatably connected to the rotating block 22, the outer wall of the fence 15 is fixedly connected to the card slot 23, the bottom of the lifting frame 1 is fixedly connected to the second hydraulic press 25, and one end of the second hydraulic press 25 is fixedly connected to the lifting platform 24.

[0033] Among them, Figure 4As shown, the block 17 is provided with a rotating groove which matches the third connecting column 16. The block 17 forms a snap-fit ​​structure with the third connecting column 16 through a spring 18, which is conducive to fixing the block 17 on the second connecting block 19 after it pops out, thereby preventing the lifting platform 24 from falling due to machine failure during high-altitude operations.

[0034] Among them, Figure 1 As shown, the sliding block 20 is provided with a rotation groove which matches the third connecting column 16. The sliding block 20 forms a rotation structure with the fence 15 through the third connecting column 16, which is conducive to closing the snap structure when descending, so that the lifting platform 24 can descend smoothly.

[0035] When in use: first, the staff turns on the first hydraulic press 2 to extend the push column 3, thereby driving the connecting frame 4 to slide downward in the groove of the lifting platform 24. The downward sliding of the connecting frame 4 will drive the first connecting column 5 and the first connecting block 6 and the second connecting column 7 connected to the first connecting column 5 to rotate, and at the same time drive the fixing frame 8 to clamp inward in the groove of the first sliding shaft 11, so as to fix the object. For high objects, the handle 10 can be pulled manually to drive the fixing block 9, so that the fixing block 9 and the rack 13 slide on the axis of the second sliding shaft 14 to achieve lifting, and at the same time drive the gear column 12 to rotate on the inner wall of the fixing frame 8 to achieve a fixing effect;

[0036] Finally, after rising to the specified position, the staff rotates upward the sliding block 20 on the outer wall of the fence 15 to prevent the block 17 from popping out, so that the block 17 pops out around the third connecting column 16 under the elastic force of the spring 18. The block 17 is irregular in shape, and after popping out, it presses against the fence 15 while the sliding block 20 presses against the block 17, so that the block 17 can be stuck to the second connecting block 19 to prevent it from falling, thereby avoiding the lifting platform 24 from falling due to machine failure during high-altitude operations, causing casualties.
