A right buckle 43 is arranged on one side of the right connecting block 41, a lead screw 5 is arranged in the threaded hole 37, a torsion wheel 51 is installed at one end of the lead screw 5, and a rubber block 52 is installed at the other end of the lead screw 5.

[0022] The inner diameter dimension of the spring 2 is larger than that of the corrugated pipe 1, the inner diameter dimension of the through hole 42 is larger than that of the corrugated pipe 1, the inner diameter dimension of the spring 2 is larger than that of the second connecting block 35, and the inner diameter dimension of the spring 2 is smaller than that of the limiting block 36. The distance between the springs 2 here should not be too small and the mass should not be too large, otherwise it will affect the normal use of the corrugated pipe 1. The inner diameter of the spring 2 should not be much different from that of the second connecting block 35. The spring 2 is sleeved on the second connecting block 35 to achieve the purpose of preliminary fixation by using the friction between the two. At the same time, the limiting block 36 plays a role of supporting and limiting at both ends of the spring 2.

[0023] The left buckles 32 are symmetrically installed on the first connecting block 31, the size of the groove 33 is larger than that of the right connecting block 41, and the left connecting blocks 34 are symmetrically installed at the outer wall edge of the first connecting block 31.

[0024] The outer contour of the left connecting block 34 is arc-shaped, and the length of the left connecting block 34 accounts for half of the side perimeter of the first connecting block 31.

[0025] The first connecting block 31 and the second connecting block 35 are fixedly connected, and at the same time, the first connecting block 31 and the second connecting block 35 are connected through a through hole 42.

[0026] The lead screw 5 and the threaded hole 37 are engaged with each other, and the size of the torsion wheel 51 is larger than that of the threaded hole 37. The rubber block 52 is soft in texture and will not damage the corrugated pipe 1. At the same time, the rubber block 52 can generate a large frictional force, so as to fix the left connecting head 3 and the right connecting head 4 well on the outside of the corrugated pipe 1.

[0027] The right connecting head 4 is provided with a first connecting block 31 and a second connecting block 35. The right connecting block 41 is symmetrically installed on the outer wall of the first connecting block 31. The right buckle 43 is arranged on the outer wall of the first connecting block 31, and at the same time, a groove 33 is opened inside the right buckle 43. The size of the groove 33 in the right buckle 43 is larger than that of the left connecting block 34, and the length of the right connecting block 41 accounts for half of the circumference of the first connecting block 31.

[0028] The left connecting head 3 and the right connecting head 4 should meet the following requirements: when the first connecting blocks 31 at both ends are in contact with each other and the left buckle 32 and the right buckle 43 are in a staggered state, then rotate the first connecting block 31 in the reverse direction. The left buckle 32 can move along the right connecting block 41, and the right buckle 43 moves along the left connecting block 34, and a large frictional force will be generated to fully fix the left connecting head 3 and the right connecting head 4.

[0029] Working principle: When the utility model is in use, the spring 2 is sleeved on the outside of the corrugated pipe 1, and then the left connecting head 3 and the right connecting head 4 are respectively installed at both ends of the spring 2 in opposite directions. One end of the spring 2 is sleeved on the second connecting block 35 and abuts against the limit block 36. After installing the spring 2, the left connecting head 3 and the right connecting head 4 can be appropriately moved towards the middle, so that the rubber block 52 at one end of the lead screw 5 falls on the low-lying part of the corrugated pipe 1, and then rotate the torsion wheel 51 to tighten the lead screw 5 so that it moves along the threaded hole 37 until the rubber block 52 is in close contact with the corrugated pipe 1, so that the installation of the spring 2 can be completed. When a spring 2 needs to be installed on the corrugated pipe 1, install other springs 2 on the corrugated pipe 1 according to the above method. It should be noted that the positions of the left connecting head 3 and the right connecting head 4 at this time are opposite to the original positions, and then align the left connecting head 3 with the right connecting head 4 and also make the left buckle 32 and the right buckle 43 in a staggered state, and then appropriately rotate the left connecting head 3 so that the left buckle 32 moves along the right connecting block 41 and the right buckle 43 moves along the left connecting block 34. When the left buckle 32 and the right buckle 43 are in contact with each other, the installation of the spring 2 is completed.
