The clamping assembly 101b includes a positioning rod 101b-1, and a splint 101b-3 is movably sleeved on the surface of the positioning rod 101b-1. A screw sleeve 101b-2 is installed on one side of the positioning rod 101b-1, and limiting rods 101b-21 are installed through the left and right sides of the inner cavity of the screw sleeve 101b-2.

[0030] Furthermore, the solenoid valve 101a-11 and the pressure gauge 101a-12 are both connected to the inner cavity of the storage sleeve 101a-1, and the top of the solenoid valve 101a-11 is connected to an external air pump through a pipeline.

[0032] Furthermore, a stainless steel bar 101a-13c is fixedly embedded on the top of the surface of the displacement rod 101a-13, and an electromagnet 101a-1a is fixedly embedded on the inner wall of the storage sleeve 101a-1, and the electromagnet 101a-1a is adapted to the stainless steel bar 101a-13c.

[0033] Furthermore, a limiting hole 101b-3a is formed through the clamping plate 101b-3, and the limiting hole 101b-3a is matched with the limiting rod 101b-21.

[0034] Furthermore, there are several limiting holes 101b - 3a, which are evenly distributed on the clamping plate 101b - 3.

[0035] Furthermore, a threaded tooth 101b-21a for use with the threaded sleeve 101b-2 is formed on the surface of the limiting rod 101b-21, and the threads on the surfaces of the left and right threaded teeth 101b-21a have opposite rotation directions.

[0036] Furthermore, an auxiliary sleeve 101b-11 is fixedly connected to the surface of the positioning rod 101b-1, and the outer ring of the screw sleeve 101b-2 is movably connected to the auxiliary sleeve 101b-11 through a bearing.

[0037] Furthermore, a guide block 101b-21b is fixedly connected to the surface of the limiting rod 101b-21, and a guide groove 101b-1a for use with the guide block 101b-21b is transversely opened on the surface of the positioning rod 101b-1.

[0038] Furthermore, the outer ring of the threaded sleeve 101b-2 is provided with anti-slip grooves 101b-2a, and the outer ring of the sealing head 101a-13a is in sliding contact with the inner wall of the receiving sleeve 101a-1.

[0039] Furthermore, the stainless steel bar 101a-13c is made of 440c stainless steel, which has the characteristics of high hardness, wear resistance, corrosion resistance, high strength and magnetic attraction. When the electromagnet 101a-1a is energized, it can be magnetically attracted to the stainless steel bar 101a-13c to prevent the displacement rod 101a-13 from being displaced at will.

[0040] Furthermore, the outer ring of the storage sleeve 101a-1 is fixedly connected with a reinforcing rib, and the other side of the reinforcing rib is fixedly connected to the support plate 101c. This design can effectively improve the installation stability of the storage sleeve 101a-1.

[0041] It should be noted that by providing the support plate 101c, the storage sleeve 101a-1 can be supported and installed; by providing the storage sleeve 101a-1 and the displacement rod 101a-13, the displacement rod 101a-13 can be flexibly extended and retracted to adjust the position of the clamping plate 101b-3 to clamp the pipeline well; by providing the barometer 101a-12, the internal pressure of the storage sleeve 101a-1 can be detected in real time and provided for staff to check, so as to avoid the safety hazard of excessive gas filling inside the storage sleeve 101a-1; by providing the sealing head 101a-13a, it can be in sliding contact with the inner wall of the storage sleeve 101a-1 and ensure the sealing to avoid random leakage of gas; by providing the reinforcement sleeve 101a-13b, the displacement rod 101a-13 can be connected with the positioning rod 101b-1, so that the positioning rod 101b-1 moves along with the displacement rod 101a-13 The same action, by setting the positioning rod 101b-1, can meet the needs of the movable sleeve of the splint 101b-3, by setting the auxiliary sleeve 101b-11, can carry out the installation of the screw sleeve 101b-2, and can make the screw sleeve 101b-2 flexibly rotate, by setting the guide groove 101b-1a and the guide block 101b-21b, can play the role of positioning and guiding, can avoid the limit rod 101b-21 from rotating at will, by setting the screw teeth 101b-21a and the screw sleeve 101b-2, can play the role of thread transmission, and because the two screw teeth 101b-21a surface threads rotate in opposite directions, when the screw sleeve 101b-2 is driven to rotate, the two limit rods 101b-21 will be oppositely or relatively displaced, by setting the anti-slip pattern 101b-2a, can increase the contact friction of the staff, thereby making it convenient for the staff to drive the screw sleeve 101b-2 to rotate.

[0042] When in use, all components are in the initial installation state. First, according to the specifications of the pipe to be clamped, the screw sleeve 101b-2 is reversed, and with the cooperation of the guide block 101b-21b and the guide groove 101b-1a, the two limit rods 101b-21 move inward at the same time and disengage from the limit hole 101b-3a, and then the inclination angle of the clamping plate 101b-3 is adjusted until the pipe fixing and clamping requirements are met, and the screw sleeve 101b-2 is rotated forward and reset, so that the limit rod 101b-21 is reset and inserted into the limit hole 101b-3a, ensuring that the clamping plate 101b -3 is in a stable position, and then the external air pump passes the gas into the storage sleeve 101a-1. As the gas is gradually passed in, with the cooperation of the sealing head 101a-13a, the displacement rod 101a-13 gradually moves to change the position of the clamping plate 101b-3, until the clamping plates 101b-3 arranged in front and behind clamp the pipeline for a first clamping and positioning, and then the electromagnet 101a-1a is controlled to be energized, and with the cooperation of the stainless steel bar 101a-13c, it is magnetically fixed to achieve the purpose of secondary fixing protection, thereby ensuring the stability of the clamping of the pipeline by the clamping plate 101b-3.

[0043] In summary, by setting the telescopic component 101a and the clamping component 101b, the inclination angle of the two clamps 101b-3 can be adjusted according to the actual pipeline specifications, and the limiting rod 101b-21 and the limiting hole 101b-3a can be used for limiting and fixing. Then, an external air pump will pass an appropriate amount of gas into the storage sleeve 101a-1, and the clamping plate 101b-3 will be displaced to clamp the pipeline once. Then, the electromagnet 101a-1a is controlled to be energized, and the stainless steel bar 101a-13c is used to achieve the purpose of secondary magnetic fixation, thereby ensuring the stability of the pipeline clamping.
