The L-shaped claw 7 is set up, and can be tightened against the inner wall of the wellhead to fix the steel pillar 1, so that the steel pillar 1 stands firmly at the wellhead to form a fence at the wellhead for isolation. A threaded sleeve 20 is rotatably installed at one end of the rotating column 12, and a threaded rod 22 is screwed inside the threaded sleeve 20. The threaded rod 22 passes through one end of the threaded sleeve 20. The threaded rod 22 and the threaded sleeve 20 play a role in driving the tensioning frame 6 to move. The end of the threaded rod 22 is connected to one of the tensioning frames 6. The vertical section of the lower end of the L-shaped claw 7 is set in an arc surface, which can make the L-shaped claw 7 fully contact with the inner wall of the wellhead to ensure the tightening force.

[0027] The rotating part includes two connecting seats 27 symmetrically fixedly installed at the rear end of the rotating column 12. The interiors of the two connecting seats 27 are penetrated by tensioning shafts 26 for rotation. The front ends of the two tensioning frames 6 are respectively fixed to the two tensioning shafts 26. The connecting seats 27 play the role of supporting the tensioning shafts 26. The lower ends of the two tensioning shafts 26 are coaxially inlaid with tensioning gears 30. The tensioning shafts 26 play the role of connecting the tensioning frames 6. The two tensioning gears 30 are meshed with each other. The tensioning gears 30 can make the two tensioning frames 6 rotate in opposite directions with the two No. 2 connecting shafts 25 as the center, thereby driving the two L-shaped claws 7 to move in opposite directions, so that the vertical sections of the two L-shaped claws 7 can be pressed tightly against the inner wall of the wellhead.

The connecting column 31 plays the role of connecting the L-shaped claw 7. The outer surface of the connecting column 31 is coaxially inlaid with a clamping ring 32, and the clamping ring 32 is attached to the lower end of the tension frame 6. A threaded cap 33 is screwed on the outer surface of the connecting column 31, and the threaded cap 33 is pressed against the upper end of the tension frame 6. By rotating the threaded cap 33, the tension frame 6 can be pressed against the clamping ring 32, so that the connecting column 31 can be fixed on the tension frame 6, and then the L-shaped claw 7 can be fixed. The claw 7 is fixed on the tensioning frame 6, and a No. 2 connecting shaft 25 is rotatably installed inside the shaft seat 24. The shaft seat 24 serves to connect the No. 2 connecting shaft 25. The No. 2 connecting head 23 is embedded in the outer surface of the No. 2 connecting shaft 25. A swivel 21 is coaxially fixedly installed on the outer surface of the threaded sleeve 20. The swivel 21 serves to facilitate the rotation of the threaded sleeve 20. When the threaded sleeve 20 rotates to drive the tensioning frame 6 to move, the threaded rod 22 will rotate around the No. 2 connecting shaft 25 to adapt to the movement of the tensioning frame 6.

[0032] The column fixing part includes a cylindrical shell 5 installed on the lower part of the side of the steel pillar 1. One end of the cylindrical shell 5 is open to allow the cross lock block 10 to be pushed out. A block seat 15 is fitted inside the cylindrical shell 5.

A solid shell ear 4 is fixedly installed at the front end of the cylinder shell 5, and the end of the solid shell ear 4 is fixed to the steel pillar 1, and the solid shell ear 4 serves to fix the cylinder shell 5. A fixing spring 13 is wound around the outside of the pull rod 8, one end of the fixing spring 13 is fixed to the block seat 15, and the other end of the fixing spring 13 is fixed to the inner side of the cylinder shell 5. The fixing spring 13 serves to fix the cross lock block 10 in the cross lock groove 11. Two guide edges 16 extend symmetrically on the inner surface of the cylinder shell 5, and two guide grooves 14 are symmetrically provided on the outer surface of the block seat 15. The cooperation between the guide edges 16 and the guide grooves 14 can prevent the cross lock block 10 from rotating, and the guide edges 16 fit into the inside of the guide grooves 14.

[0034] When in use, first put the steel pillar 1 at the wellhead, at this time, the horizontal section of the lower end of the L-shaped claw 7 is in contact with the ground of the road, and the vertical section of the lower end of the L-shaped claw 7 is located in the wellhead, then the threaded sleeve 20 is rotated, so that the threaded rod 22 is received into the threaded sleeve 20 by means of the thread between the threaded sleeve 20 and the threaded sleeve 20. In this process, the moving threaded rod 22 will pull the tensioning frame 6, so that the two tensioning frames 6 can rotate in opposite directions with the two No. 2 connecting shafts 25 as the center under the action of the tensioning gear 30, thereby driving the two L-shaped claws 7 to move in opposite directions, so that the vertical sections of the two L-shaped claws 7 can be pressed against the inner wall of the wellhead, so as to fix the steel pillar 1 and make the steel pillar 1 stand firmly at the wellhead, so as to form a tensioning frame 6 at the wellhead. The two tension frames 6 can be isolated by forming a fence. When use is completed, the threaded sleeve 20 can be rotated in the opposite direction to push the tensioning frame 6, so that the two tensioning frames 6 can rotate towards each other with the two No. 2 connecting shafts 25 as the center under the action of the tensioning gear 30, so that the two tensioning frames 6 can be close together, and then the pull ring 9 is pulled to allow the fixing spring 13 to shrink, so that the cross lock block 10 pushed by the fixing spring 13 can be disengaged from the cross lock groove 11, so that the rotating column 12 can rotate without the locking of the cross lock block 10, thereby driving the tensioning frame 6 to flip, so that the two tensioning frames 6 close together can be erected to stand on the rear end of the steel pillar 1, thereby reducing its space footprint for easy storage and carrying.
