[0007] The effect achieved by the above components is: when installing the pipeline, the pipeline can be placed on the arc-shaped hollow plate on the support block, so that the arc-shaped hollow plate moves downward under the gravity of the pipeline, driving the abutment rod to slide downward on one side of the support block, abutting and pushing one end of the limit rod to rotate in the inner wall of the bracket with the circular axis as the center, driving the second torsion spring to deform, so that the other end of the limit rod is close to the outer surface of the pipeline, clamping it, and at the same time, the rotated limit rod is fixed on the bracket with the help of the limit device. When the arc-shaped hollow plate moves downward, it will also drive the first piston rod to slide downward on the support block and in the inner wall of the rectangular cavity, thereby pressing the rectangular cavity. The air inside below the first piston rod is squeezed, driving the fitting mechanism to fill the gap between one end of the limit rod and the pipe, so that one end of the limit rod fits more firmly with the pipe surface, thereby improving the stability of clamping; at the same time, when the first piston rod slides downward in the rectangular cavity, the space above the first piston rod in the rectangular cavity will become larger, driving the auxiliary mechanism to perform secondary fixation and limit on the surface of the pipe, so that the pipe is not prone to shaking after being placed on the arc-shaped hollow plate.

At this time, when the first piston rod slides downward in the rectangular cavity, it will also drive the air pipe to move downward, and the space above the first piston rod in the rectangular cavity will become larger, and the air inside the arc-shaped hollow plate and the air inside the suction cup fitted on the surface of the pipeline will be sucked into the rectangular cavity, so that the suction cup can perform secondary fixation on the surface of the pipeline, so that the pipeline will not easily shake after being placed on the arc-shaped hollow plate, thereby improving the stability of clamping and fixing.

[0012] Preferably, the auxiliary mechanism further comprises a protective block, wherein the protective block is fixedly mounted on one end of the second piston rod and is made of rubber.

[0013] The effect achieved by the above components is that by providing the protection block, one end of the second piston rod can be protected so that after the pipeline abuts against the second piston rod, it is not easy to be damaged by friction therewith.

At this time, the clamping block will first shrink into the inner wall of the slide groove, driving the third spring to shrink, and then when one end of the limit rod is rotated to a certain angle, under the resetting action of the third spring, it can drive one end of the clamping block to be inserted into the corresponding clamping groove, and the limit rod after rotation adjustment is fixed and limited, so that it can clamp the pipeline more firmly. In this way, when the pipeline is pulled upward to release gravity, the limit rod will not open, and the pipeline will be clamped and fixed.

When the arc hollow plate 24 moves downward, it will drive the first piston rod 22 to slide downward on the support block 5 and the inner wall of the rectangular cavity 21, squeeze the air below the first piston rod 22 in the rectangular cavity 21, squeeze the air into the hose 291, and then enter the plurality of air bags 293 through the arc block 292, so that the air bags 293 expand, fill the gap between the arc block 292 and the pipeline, increase the contact area between the arc block 292 and the pipeline, thereby improving the clamping stability. At the same time, the first piston rod 22 is in the rectangular cavity 2 1 slides downward, the air pipe 256 will also be driven to move downward, the space above the first piston rod 22 in the rectangular cavity 21 will become larger, and the air inside the arc hollow plate 24 and the air inside the suction cup 251 attached to the pipe surface will be sucked into the rectangular cavity 21, so that the suction cup 251 can perform secondary fixation on the surface of the pipe, so that the pipe is not easy to shake after being placed on the arc hollow plate 24. Through this operation, the pipe can be automatically fixed and limited under the action of gravity, which can simplify the installation process when supporting and fixing, reduce the time, and improve the efficiency of pipe installation.

[0035] When the abutment rod 211 moves downward to abut against one end of the limit rod 27, the limit rod 27 will rotate in the inner wall of the bracket 26 with the help of the round shaft 28. At this time, the block 33 will first shrink into the inner wall of the slide groove 32, driving the third spring 34 to shrink. Then, when one end of the limit rod 27 rotates to a certain angle, under the reset action of the third spring 34, one end of the block 33 can be driven to be inserted into the corresponding slot 31, and the limit rod 27 after rotation adjustment is fixed and limited, so that it can clamp the pipeline more firmly. In this way, when the pipeline is pulled upward to release gravity, the limit rod 27 will not open, and the pipeline will be clamped and fixed.
