[0034] Specifically, before using the machine, the object to be processed is placed on the placement ring 36, and the hydraulic press 26 installed on the bottom wall inside the body 1 is started. The hydraulic press 26 extends the hydraulic rod 2 to push upward, and the fixed base 27 is pushed upward by the upward force. Inside the U-shaped hollow short piece 2 38, the other end of the fixed plate 39 is rotatably connected to the rotating column 1 22, which will drive the above objects to be tightened inward and drive the fixed long block 33 on the top wall of the fixed U-shaped hollow short piece 1 35 to be tightened inward. Because the machine may be damaged at an uncertain time during use, a storage box 17 is fixedly connected to the outer wall of the body 1, and the top of the storage box 17 is slidably connected to a cover plate 18 for storing daily maintenance tools. Considering that the workers cannot illuminate the machine-processed part during processing, an electric wire 4 is installed on the right side of the outer wall of the body 1, and a light bulb 5 is installed at the end of the electric wire 4 for auxiliary lighting.

[0035] Reference Figure 2 、 Figure 5 and Figure 6 The telescopic mechanism 2 includes an internal threaded rod 201, which is fixedly connected to the front right end of the body 1. The inner wall of the internal threaded rod 201 is threadedly connected to the external threaded rod 202.

The outer side of the body 1 is fixedly connected to a hook 3.

[0036] Specifically, after the machine processing is completed, the worker waits for the hydraulic press 9 to be lifted up, and then rotates the internal threaded rod fixed at the right end of the front side of the machine body 1. The internal threaded rod 201 and the external threaded rod 202 are threadedly rotated to adjust the height, and then the two handles fixed at the bottom of the fixed plate 204 are grasped to clamp items. Because the workers will bump against the corners of the machine when working, protective pads 13 are threadedly connected at the four corners of the top wall of the machine body 1, and the top wall of the protective pad 13 is threadedly connected with a screw 2 12 to protect the workers. Considering that the machine needs to be cleaned frequently to ensure the normal operation of the machine, a hook 3 is fixedly connected to the outside of the machine body 1 for hanging cleaning tools.

[0037] Reference Figure 1 and Figure 2 The left and right sides of the outer wall of the body 1 are fixedly connected with handles 20, the outer wall of the handle 20 is fixedly connected with an anti-slip sleeve 19, the outer wall of the body 1 is fixedly connected with a circular support 15, and the end of the circular support 15 is fixedly connected with a placement ring 14;

[0038] Specifically, considering that the machine may need to be carried and transferred on a daily basis, handles 20 are fixedly connected to the left and right sides of the outer wall of the body 1, and the outer wall of the handle 20 is fixedly connected to an anti-slip sleeve 19 to prevent the hand from slipping and falling. After the machine is in operation, its important parts need to be frequently coated with lubricating fluid to maintain the operation of the machine. Because the lubricating fluid is a liquid and may leak when stored together with other tools, a circular pillar 15 is fixedly connected to the outer wall of the body 1, and a circular ring 14 is fixedly connected to the end of the circular pillar 15 for storing liquid cleaning items.

[0039] Working principle: First, the object to be processed is placed on the placement ring 36, and then the hydraulic press 26 installed on the bottom wall of the body 1 is started. The hydraulic press 26 extends the hydraulic rod 2 and pushes upward. The fixed base 27 is fixedly connected to the middle of the top wall of the fixed base 27 with a fixed support 28. Since the fixed support 28 receives an upward force, it pushes the U-shaped hollow long piece 29. Since the U-shaped hollow long piece 29 is fixedly connected to the outer wall of the hollow column 24, the hollow column 24 will slide up and down on the outer wall of the fixed column 30. The second rotating column 25 in the long piece 29 is rotatably connected to the connecting column 23. The other end of the connecting column 23 is rotatably connected to the fourth rotating column 40 in the second U-shaped hollow short piece 38. The fourth rotating column 40 is rotatably connected to the fixed plate 39. Inside the second U-shaped hollow short piece 38, the other end of the fixed plate 39 is rotatably connected to the first rotating column 22. Therefore, when the machine applies force upward, it will drive the above objects to tighten inward, driving the fixed long block 33 that fixes the outer top wall of the U-shaped hollow short piece 35. The fixed long block 33 achieves the fixing effect on the processed object.

[0040] Then start the hydraulic press 9 fixed on the middle of the top wall of the square block 8 for processing. After the processing is completed, the hydraulic press 9 is raised up, and the worker adjusts the threaded inner threaded rod 201 and the outer threaded rod 202 fixed on the right end of the front side of the machine body 1 to the required height. Then, hold the two handles fixed on the bottom of the fixed plate 204, tighten them inward to clamp and take the material, replacing the workers' manual material taking steps to reduce risks and improve safety.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
