In this embodiment, a tightening block 5 and a contact block 6 are fixedly mounted on the free end of each elastic plate 4, and the tightening block 5 is located on the side of the elastic plate 4 facing the inner side of the plug-in ring 21, and the contact block 6 is located on the side of the elastic plate 4 facing the outer side of the plug-in ring 21, and the plurality of tightening blocks 5 and the contact blocks 6 are arranged in a ring with the axis of the plug-in ring 21 as the reference. In some embodiments, the free end of each elastic plate 4 can only be fixedly mounted with a tightening block 5 located on the side of the elastic plate 4 facing the inner side of the plug-in ring 21; in some embodiments, the free end of each elastic plate 4 can only be fixedly mounted with a contact block 6 located on the side of the elastic plate 4 facing the outer side of the plug-in ring 21.

[0037] Reference Figure 2 and Figure 3 Each of the abutting blocks 5 has a abutting surface 7 on the side wall facing away from the elastic plate 4, which matches the shape of the outer surface of the cable. The abutting surface 7 helps prevent multiple abutting blocks 5 from damaging the cable surface, thereby helping to improve the safety of the cable and ensure the service life of the cable. Each of the abutting blocks 5 has an introduction slope 8 on the side wall facing the abutment joint 22, and the distance between the end of the introduction slope 8 close to the abutment joint 22 and the elastic plate 4 is smaller than the distance between the end of the introduction slope 8 away from the abutment joint 22 and the elastic plate 4; each of the abutting blocks 6 has a guide slope 9 on the side wall facing away from the abutment joint 22, and the distance between the end of the guide slope 9 close to the abutment joint 22 and the elastic plate 4 is larger than the distance between the end of the guide slope 9 away from the abutment joint 22 and the elastic plate 4.

[0038] Reference Figure 2 and Figure 3 Two clamping grooves 10 are formed on the circumference of one end of the gun housing 1 near the wire tail sleeve 2, and two installation grooves 11 are formed on the circumference of the plug ring 21. Two elastic connecting plates 12 are fixedly installed on the plug ring 21. Each elastic connecting plate 12 is located in a installation groove 11 and one end of each elastic connecting plate 12 is fixedly connected to the plug ring 21. A clamping block 13 is fixedly installed on the other end of each elastic connecting plate 12, and each clamping block 13 is clamped in a clamping groove 10. A positioning block 14 is fixedly installed on the outer ring of the plug ring 21 along the axial direction of the plug ring 21. A positioning groove 15 is formed on the inner wall of the gun housing 1, and the positioning block 14 is inserted in the positioning groove 15.

[0039] Reference Figure 2 and Figure 3, insert the cable into the wire hole 17 of the abutment 22, and then insert the cable into the plug ring 21 after passing through the wire hole 17. When the cable is inserted into the plug hole, the introduction of the inclined surface can prevent the abutment block 5 from obstructing the insertion of the cable during the insertion process, which helps to improve the smoothness of the cable insertion into the plug ring 21. Multiple annularly arranged abutment blocks 5 are all pressed against the outer surface of the cable, so that the free ends of the multiple elastic plates 4 are offset in the direction away from the cable, thereby driving the abutment block 6 to move toward the periphery of the plug ring 21, so that the end of the abutment block 6 away from the elastic plate 4 is higher than the outer wall of the plug ring 21.

[0040] Reference Figure 2 and Figure 3 After the cable insertion is completed, the plug ring 21 is inserted into the gun case 1. In the process of inserting the plug ring 21 into the gun case 1, the positioning block 14 is first inserted into the positioning groove 15, which helps to guide and limit the insertion position of the plug ring 21; at the same time, the guide slope 9 helps to prevent the abutment block 6 from abutting against the side wall of the gun case 1 during the process of inserting the plug ring 21 into the gun case 1, which makes the plug ring 21 unable to be inserted into the gun case 1, and helps to improve the smoothness of the plug ring 21 inserted into the gun case 1.

[0041] Reference Figure 2 and Figure 3 Under the guidance of the positioning block 14, the plug-in ring 21 is gradually inserted into the gun housing 1, so that the multiple contact blocks 6 higher than the outer wall of the plug-in ring 21 drive the multiple tightening blocks 5 to move toward the inside of the plug-in ring 21 under the extrusion force of the inner wall of the gun housing 1, so that the tightening blocks 5 press against the surface of the cable, and at the same time help to make the plug-in ring 21 firmly plugged into the gun housing 1, thereby improving the convenience of the operation process of locking and fixing the cable, thereby improving the operation efficiency of locking and fixing the cable.

[0042] Reference Figure 2 and Figure 3 When the clamping block 13 moves to the corresponding clamping slot 10 position, under the elastic action of the elastic connecting plate 12, each clamping block 13 slides into the clamping slot 10 driven by the elastic connecting plate 12, so that the clamping block 13 is clamped and fixed in the clamping slot 10, which helps to limit the relative position between the plug-in ring 21 and the gun housing 1, and further improves the stability of the relative position between the cable locked and fixed in the plug-in ring 21 and the gun housing 1.

[0043] Reference Figure 1 and Figure 3A sealing ring 16 is fixedly connected to the end surface of the plug-in ring 21 facing away from the abutment joint 22. The circumferential outer surface of the sealing ring 16 has an interference fit with the inner wall of the gun housing 1, and the circumferential inner surface of the sealing ring 16 has an interference fit with the outer surface of the cable. The sealing ring 16 helps to block the gap between the plug-in ring 21 and the gun housing 1 and the gap between the cable and the plug-in ring 21, thereby helping to prevent external water from entering the interior of the gun housing 1, thereby improving the waterproof sealing effect inside the gun housing 1.

[0044] The implementation principle of the embodiment of the present application is as follows: insert the cable into the wire hole 17 of the abutment 22, and then insert the cable into the plug ring 21 after passing through the wire hole 17. When the cable is inserted into the plug hole, the introduction of the inclined surface can prevent the abutment block 5 from obstructing the insertion of the cable during the insertion process, which helps to improve the smoothness of the cable insertion into the plug ring 21. Multiple annularly arranged abutment blocks 5 are all pressed against the outer surface of the cable, so that the free ends of the multiple elastic plates 4 are offset in the direction away from the cable, thereby driving the abutment block 6 to move toward the periphery of the plug ring 21, so that the end of the abutment block 6 away from the elastic plate 4 is higher than the outer wall of the plug ring 21.

[0045] After the cable is inserted, the plug-in ring 21 is gradually inserted into the gun case 1, so that the multiple contact blocks 6 higher than the outer wall of the plug-in ring 21 drive the multiple tightening blocks 5 to move toward the inside of the plug-in ring 21 under the action of the squeezing force of the inner wall of the gun case 1, so that the tightening blocks 5 press against the surface of the cable, and at the same time help to make the plug-in ring 21 firmly plugged into the gun case 1, thereby improving the convenience of the operation process of locking and fixing the cable, thereby improving the operation efficiency when locking and fixing the cable.

[0046] When the clamping block 13 moves to the corresponding clamping slot 10 position, under the elastic action of the elastic connecting plate 12, each clamping block 13 slides into the clamping slot 10 driven by the elastic connecting plate 12, so that the clamping block 13 is clamped and fixed in the clamping slot 10, which helps to limit the relative position between the plug-in ring 21 and the gun housing 1, and further improves the stability of the relative position between the cable locked and fixed in the plug-in ring 21 and the gun housing 1.

[0047] A sealing ring 16 is fixedly connected to the end surface of the plug-in ring 21 facing away from the abutment joint 22. The circumferential outer surface of the sealing ring 16 has an interference fit with the inner wall of the gun housing 1, and the circumferential inner surface of the sealing ring 16 has an interference fit with the outer surface of the cable. The sealing ring 16 helps to seal the gap between the plug-in ring 21 and the gun housing 1 and the gap between the cable and the plug-in ring 21, thereby helping to prevent external water from entering the interior of the gun housing 1, thereby improving the waterproof sealing effect inside the gun housing 1.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
