[0027] In this embodiment, this design can effectively solve the problem that when the crack in the bumper is subjected to a lateral pulling force, the tensioning ribs in a single direction cannot tighten it, which may cause the crack to deepen or even deform.

[0028] In the preferred embodiment of the present invention, please refer to Figure 4 The lower screwing assembly 4 includes: a first inner column 41, the first inner column 41 is fixedly connected to the bottom of the first middle column 44, and the lower screwing assembly 4 also includes a first screw handle 42, the first screw handle 42 is annular and fixedly connected to the outside of the first inner column 41. By providing the first screw handle 42 on the outside of the first inner column 41, it is convenient for the staff to screw the first inner column 41 and the first middle column 44.

[0029] In this embodiment, the lower screwing assembly 4 also includes: a top sleeve 43, which is fixedly connected to the outside of the first middle column 44 and located below the first thread 441. The top sleeve 43 can limit the first middle column 44 during the rotation and advancement process.

[0030] In this embodiment, by twisting the first handle 42, the first thread 441 on the outside of the first center column 44 is screwed into the thread groove 22 until the top sleeve 43 in the middle of the first center column 44 abuts against the lower part of the positioning plate 31.
