The implementation principle of the embodiment is as follows: the hand wheel 632 is rotated to rotate the horizontal shaft 631, the horizontal shaft 631 rotates to drive the worm 633 to rotate, the worm 633 rotates to drive the worm gear 634 to rotate, the worm gear 634 rotates to drive the lead screw 61 to rotate, so that the connecting block 33 can be driven to move downwards, the connecting block 33 moves downwards to drive the first inserting block 34 to move downwards, and therefore the first inserting block 34 can be inserted into the first inserting hole 35; the first block 34 moves downward to drive the block 451 to move downward, and the fourth spring 452 is in a compressed state; when second inserted block 43 aims at second jack 46, second inserted block 43 pegs graft with second jack 46 under the effect of third spring 44 this moment to alright fix first inserted block 34, second arc 372 butt in new tuber pipe 1 this moment, therefore be convenient for carry out the shock attenuation to new tuber pipe 1.

The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
