The sliding path of the moving rod 32 is arc-shaped, and the shape of the slide groove 31 is approximately semicircular. The outer wall diameter of the moving rod 32 is smaller than the difference between the inner and outer diameters of the slide groove 31.

The outer wall of the moving rod 32 is provided with a positioning block 33, and the rear side of the positioning block 33 away from the end of the moving rod 32 is rotatably connected to the front end of the mounting plate 2.

The interior of the positioning block 33 is set to be hollow, and the cross-sectional shape of the end of the hollow interior of the positioning block 33 close to the moving rod 32 is an arc shape, and the side close to the moving block 34 is set to be square. Through the setting of the shape of the positioning block 33, it is ensured that the positioning block 33 can be in good contact with the surface of the moving rod 32 while ensuring that the moving block 34 is not affected when it moves inside the positioning block 33. A control rod 35 is passed through and fixedly connected to the inner wall of the moving block 34. The material of the control rod 35 on the side close to the mounting plate 2 is set to iron, and the material of the inner wall of the positioning block 33 on the side away from the moving rod 32 is set to a magnet. Through the setting of the material, it is ensured that when the control rod 35 and the moving block 34 are in the position closest to the middle of the mounting plate 2, there is a force to fix them.

[0033] Reference Figure 1 - Figure 3 The inner wall of the moving rod 32 is provided with a gas pressure chamber 36, and the inner wall piston of the gas pressure chamber 36 is connected with a slide plate 37. The shape of the gas pressure chamber 36 is approximately L-shaped, and the outer wall of the slide plate 37 fits with the inner wall of the gas pressure chamber 36. By fitting, it is ensured that the gas inside the gas pressure chamber 36 cannot communicate with the outside. The front end of the slide plate 37 is rotatably connected with a threaded rod 38, and the outer wall of the threaded rod 38 penetrates and is threadedly connected with the inner wall of the moving rod 32. The outer wall of the moving rod 32 is fixedly connected with an air bag 39, which is annular in shape and made of rubber. The air bag 39 is connected with the inside of the gas pressure chamber 36.

[0034] Reference Figure 2 - Figure 4 The front end of the control rod 35 is provided with a clamping assembly 4, and the clamping assembly 4 includes a fixed shell 41. The rear end of the fixed shell 41 is fixedly connected to the front end of the control rod 35. The number of the clamping assemblies 4 is set to two groups. Through the setting of the two groups of clamping assemblies 4, it is ensured that both ends of the material pipe can be clamped. The other group of clamping assemblies 4 is set at the front end of the moving rod 32. Through the setting of the shape of the air pressure chamber 36, it is ensured that the threaded rod 38 and the setting of the clamping assembly 4 do not interfere with each other. The rear end of the fixed shell 41 in the other group of clamping assemblies 4 is fixedly connected to the front end of the moving rod 32. The inner wall of the fixed shell 41 penetrates and A screw rod 42 is threadedly connected, a connecting rod 43 is hinged on the outer wall of the screw rod 42, a fixing rod 44 is hinged on one end of the connecting rod 43 away from the screw rod 42, and the material of the end of the fixing rod 44 away from the connecting rod 43 is set to soft rubber. Through the setting of the material, it is ensured that the end of the fixing rod 44 can produce a certain degree of deformation to ensure that it fits with the inner wall of the material tube. The outer wall of the fixing rod 44 penetrates and is slidably connected with the inner wall of the fixing shell 41. The number of fixing rods 44 and connecting rods 43 in each group of clamping assemblies 4 is consistent and not less than three, and the material of the end of the fixing rod 44 away from the connecting rod 43 is set to soft rubber.

[0035] Working principle: When in use, the staff first moves the moving block 34 and the control rod 35 to the middle position of the positioning block 33. At this time, the control rod 35 is relatively fixed relative to the positioning block 33 under the magnetic force of the positioning block 33. Then the staff puts one end of the material tube into the outside of the fixed shell 41 outside the control rod 35, and then the staff rotates the screw 42 to increase the area of ​​the screw 42 entering the inside of the fixed shell 41.

[0036] As the length of the screw rod 42 entering the inner area of ​​the fixed shell 41 increases, the screw rod 42 pushes the connecting rod 43, so that the end of the connecting rod 43 close to the screw rod 42 moves toward the direction close to the fixed rod 44, so the angle between the connecting rod 43 and the fixed rod 44 increases, so the fixed rod 44 moves toward the outside of the fixed shell 41, so that the end of the fixed rod 44 outside the fixed shell 41 contacts and fits with the inner wall of the material pipe, thereby achieving the effect of fixing the material pipe.

[0037] When one end of the material tube is fixed, the staff moves the moving rod 32, so that the moving rod 32 drives the positioning block 33 to rotate, and the rotation of the positioning block 33 causes the moving block 34 and the control rod 35 to rotate, thereby changing the inclination angle of the material tube. When the inclination angle of the material tube is adjusted to a suitable state, the staff rotates the threaded rod 38, so that the threaded rod 38 enters more of the internal area of ​​the control rod 35, thereby pushing the slide plate 37, and through the movement of the slide plate 37, the gas inside the air pressure chamber 36 is pushed into the airbag 39, thereby causing the airbag 39 to expand, so that the control rod 35 and the inner wall of the slide 31 are relatively fixed.

[0038] When the fixation is completed, the staff pushes the control rod 35 and the moving block 34. Since the control rod 35 and the positioning block 33 are only fixed by magnetic force, after the artificial thrust is generated, the control rod 35 can drive the moving block 34 to move and make the material tube move toward the fixed shell 41 on the side close to the moving rod 32.

[0039] When the material pipe moves to the outside of the fixed shell 41 where the other end is close to the moving rod 32, the staff repeats the above fixing operation to fix the other end of the material pipe. At this time, since both ends of the material pipe are fixed, the moving block 34 and the control rod 35 are restrained by the material pipe and cannot move inside the positioning block 33. Therefore, the material pipe is better fixed at this time, and the staff can process the fixed material pipe as needed.

[0040] 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 substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
