[0029] like Figure 4 As shown, the fixing assembly 4 includes an adjusting head 41 movably sleeved inside the mounting seat 11, a fastening rod 42 is integrally formed on one side of the adjusting head 41, the other end of the fastening rod 42 passes through the mounting seat 11, and the outer surface of the fastening rod 42 extending to the outside of the mounting seat 11 is provided with a thread.

[0032] like Figure 2 As shown, the inner sliding clamp of the limit sliding groove 21 is connected with the limit adjustment block 24, the limit adjustment block 24 is located at the end of the buffer spring 23 away from the center of the mounting seat 11, and the limit adjustment block 24 is connected to the buffer spring 23;

[0038] The working principle and use process of this utility model:
[0039] The device is fixedly installed in front of the advancing direction of the steel pipe by the fixing component 4. When the steel pipe approaches, it first contacts the buffer abutment block 27 through the limiting sliding cavity 3. As the steel pipe continues to advance under the inertia of the steel pipe, it will push multiple buffer abutment blocks 27 to spread around with the cooperation of the limiting sliding cavity 3. With the movement of the buffer abutment block 27, the limiting slider 22 can be driven away from the center of the mounting seat 11, and the buffer spring 23 is compressed with the cooperation of the limiting sliding groove 21, the limiting adjustment block 24 and the limiting adjustment rod 25 to enhance its elastic force recovery effect, thereby achieving a buffering effect.
[0040] The deformation strength of the buffer spring 23 can be adjusted for steel pipes with different inertia strengths, that is, the adjusting sleeve 12 is rotated to drive several linkage gears 26 to rotate simultaneously through the linkage ring 13. Since the rotation of the linkage gear 26 can drive the limit adjustment rod 25 to rotate, and the rotation of the limit adjustment rod 25 can move the limit adjustment block 24 under the restriction of the limit slide groove 21, the initial distance between the limit adjustment block 24 and the limit slide block 22 can be changed, thereby changing the initial state of the buffer spring 23, so as to cope with steel pipes with different inertia strengths.
