[0021] Embodiment 2

[0022] On the basis of Example 1, in order to achieve buffering protection for the cable, three groups of springs 3 are fixed to the inner walls at both ends of the upper shell 1 and the lower shell 2, one end of the spring 3 is fixed to the inner wall of the upper shell 1, and the other end of the spring 3 is fixed to the rubber plate 4, and the rubber plate 4 has an arc-shaped plate structure. The distribution of the spring 3 and the rubber plate 4 on the inner wall of the lower shell 2 is consistent with the distribution on the inner wall of the upper shell 1.

[0023] When the upper shell 1 and the lower shell 2 are hit, the spring 3 and the rubber plate 4 will absorb part of the force to protect the cable. At the same time, the rubber plate 4 also clamps and limits the cable to prevent the cable from sliding between the upper shell 1 and the lower shell 2.

[0024] Embodiment 3

[0025] On the basis of the second embodiment, in order to achieve the fixation of the upper shell 1 and the lower shell 2, the top surface of the upper shell 1 is provided with a first groove 5 at the four corners, the top surface of the lower shell 2 is provided with a second groove 6 at a position corresponding to the first groove 5, and the top surface of the lower shell 2 is provided with a third groove 7. The third groove 7 is provided with two groups, and the two groups of third grooves 7 are symmetrical about the second groove 6. The third groove 7 is connected with the second groove 6. A limiting groove 8 is provided on the bottom surface of the lower shell 2. The diameter of the limiting groove 8 is greater than the diameter of the second groove 6. The limiting groove 8 is connected with the second groove 6 and the third groove 7. A rotating rod 9 is inserted in the first groove 5, and the rotating rod 9 extends upward to the outside of the upper shell 1, and the rotating rod 9 extends downward into the limiting groove 8; the rotating rod A limit block 10 is fixed to the side wall at the lower end of 9, and two groups of limit blocks 10 are provided. The two groups of limit blocks 10 are symmetrically arranged about the rotating rod 9, and the limit blocks 10 are in contact with the top surface of the limit groove 8. A limit ring 11 is fixedly sleeved on the side wall at the upper end of the rotating rod 9, and a rubber ring 12 is fixedly sleeved on the outer side of the limit ring 11. A sleeve 13 is movably sleeved on the side wall at the upper end of the rotating rod 9, and an annular groove 14 is provided on the inner wall of the sleeve 13.
