The depth of the first cylindrical groove 12 is shallow and the depth of the second cylindrical groove 21 is deep. The protective sleeve 6 is fixedly installed on one side of the second cylindrical groove 21, and the protective sleeve 6 can pass through the protective sleeve 6. The protective sleeve 6 is mainly used to protect the insulation skin of the wire 5 to prevent it from breaking due to excessive bending. The protective ring 8 is clamped in the first cylindrical groove 12. The protective ring 8 is annular and the protective ring 8 can just extend into the first cylindrical groove 12 and be clamped with it. Several elastic rods 9 are fixedly installed on one side of the protective ring 8.
[0022] A second through hole 13 is provided between the first cylindrical groove 12 and the second cylindrical groove 21. The second through hole 13 is for better use of the elastic rod 9. The first cylindrical groove 12 and the second cylindrical groove 21 are connected through the second through hole 13. The inner wall of the second through hole is inclined. The inclined setting is to allow the elastic rod 9 to contract when passing through the second through hole 13. Once contracted, the wire 5 can be firmly fixed. A first clamping block 11 is installed at one end of each elastic rod 9. The first clamping block 11 will extend into the second through hole 13 with the elastic rod 9.
