DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example

[0021] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0022] It includes a cava seat body 1, the top of which is equipped with a support plate 3 through a plurality of connecting rods 2, the outer wall of the cava seat body 1 is symmetrically equipped with a plurality of mounting blocks 6, the inner walls of the plurality of mounting blocks 6 are threadedly connected with adjusting bolts 7, the bottom ends of the plurality of adjusting bolts 7 are rotatably equipped with clamping blocks 8 through a set rotating shaft, the outer wall of the cava seat body 1 is sleeved with a first base 4 and a second base 5, the top of the first base 4 is fixedly connected with the bottom end of the second base 5, the top of the second base 5 is provided with a plurality of clamping grooves 16, the outer walls of the plurality of adjusting bolts 7 are clamped and connected with the inner walls of adjacent clamping grooves 16, the front sides of the plurality of clamping blocks 8 are provided with tenons 11, and the two sides of the plurality of clamping blocks 8 are provided with wedge blocks 14.

[0023] In this embodiment, the front sides of the plurality of blocks 8 are provided with limiting grooves 9, the inner walls of the plurality of limiting grooves 9 are fixedly connected with a plurality of first tension springs 10, one ends of the plurality of groups of first tension springs 10 are fixedly connected to the outer walls of adjacent tenons 11, and the first tension springs 10 can drive the tenons 11 to leave the limiting grooves 9 when not subject to force, and can be retracted into the limiting grooves 9 for storage during the downward pressing process.

[0024] In this embodiment, the inner wall of the first base 4 is symmetrically provided with a plurality of tenons 17, and the outer walls of the plurality of tenons 11 are snap-fitted and connected with the inner walls of adjacent tenons 17. The tenons 17 and the tenons 11 are snap-fitting structures, which can increase friction during installation and play a role in stabilizing the limit.

[0025] In this embodiment, auxiliary grooves 12 are opened on both sides of multiple blocking blocks 8, and the inner walls of multiple auxiliary grooves 12 are fixedly connected with second tension springs 13. The heights of multiple auxiliary grooves 12 are greater than the heights of adjacent second tension springs 13. One ends of multiple second tension springs 13 are fixedly connected with the outer walls of adjacent wedge blocks 14. The non-adjacent sides of the bottom ends of multiple groups of wedge blocks 14 are fixedly connected with L-shaped hook blocks 15. Multiple hook plates 18 are fixedly installed on the top of the first base 4. The outer walls of multiple L-shaped hook blocks 15 are engaged with the inner walls of adjacent hook plates 18. When the second tension spring 13 drives the wedge block 14 to move, it can drive the L-shaped hook block 15 to enter the inner wall of the hook plate 18 for engagement, thereby increasing the limiting strength of the blocking block 8 on the inner wall of the blocking groove 16.

[0026] Working principle: When in use, first install the first base 4 at the wellhead position, penetrate the cava seat body 1 between the first base 4 and the second base 5, and then install it at the wellhead position. At this time, by rotating multiple adjusting bolts 7, the block 8 is driven to descend and penetrate into the card slot 16 with the cooperation of the rotating shaft. The block 8 squeezes the inclined surface of the tenon 11 during the descent process, and can drive the tenon 11 to shrink to the near limit slot 9 under the connection of the first tension spring 10. After the tenon 11 is not subjected to force, the tenon 11 pops out and is engaged with the tenon slot 17 under the tension of the first tension spring 10 for limiting. Similarly, when the adjusting bolt 7 is descended, it drives the second tension spring 13 to shrink into the auxiliary slot 12, and drives the wedge block 14 to pop out when there is no force, and makes the L-shaped hook block 15 engage with the corresponding hook plate 18, thereby increasing the fixing strength of the connecting rod 2 and improving the stability of the connecting rod 2.
