At the same time, the cable can be locked to prevent the cable from being separated, thereby improving the overall connection effect and the firmness of the connection, and facilitating use.

[0057] The present invention utilizes a configuration mode in which the sleeve, the rotating plate, the sliding rod, the extruding plate, the first compression spring, the skin cutting component and the clamping component cooperate with each other, and drives the extruding plate to move and rotate through the sleeve, so that the rotating plate can rotate in different directions, and the skin cutting component and the clamping component can be switched, so that when the skin cutting component cuts the outer wall of the cable, the clamping component shrinks inside the connecting sleeve, and after cutting, the skin cutting component can be switched to be stored inside the connecting sleeve, and the clamping component clamps the cut cable, so that the internal metal wire can be clamped on the connecting tube, thereby accelerating the efficiency of cable connection and ensuring the stability and safety of the connection.

[0058] The present invention utilizes the arrangement mode of matching the clamping plate, the fixed teeth, the connecting rod, the positioning block, the fourth compression spring, the pressing plate and the sliding block, and utilizes the elastic force of the fourth compression spring to enable the positioning block to be closely attached to the positioning groove provided by the sleeve, thereby limiting the sleeve and preventing the sleeve from rotating to affect the state of the skin cutting clamping mechanism. At the same time, the positioning groove can also be used to squeeze the positioning block, so that the fixed teeth on the clamping plate can tightly fix the cable, and when disassembling, it only needs to slide the positioning block into the positioning hole to release the clamping, which is simple and convenient to operate.

[0059] The present invention utilizes a configuration mode in which the dust cover, the clamping rod, the plugging rod and the anti-slip pad are matched, and the dust cover can be positioned at the end of the connecting sleeve by the plugging rod, so that when the clamping plate descends to clamp the cable, the clamping groove and the clamping rod can be clamped, so that the dust cover can play a dustproof role while not being easily dropped off, and is easy to use;

[0060] The present invention utilizes a configuration in which the heat exchange ring and the heat exchange rod are matched to effectively control the temperature inside the connecting sleeve, ensuring that the cable will not be damaged or performance will not be degraded due to excessive temperature during the connection process. Proper temperature management can extend the service life of the cable, prevent safety hazards caused by overheating, and improve the reliability of the connection. BRIEF DESCRIPTION OF THE DRAWINGS

The second compression spring 364 is located inside the cutter 362. 4 is fixedly connected to the fixing rod 363, and the other end of the second compression spring 364 is fixedly connected to the inner wall of the cutter 362. The second compression spring 364 is always in a compressed state, thereby providing an elastic force for the cutter 362 to move toward the center of the connecting sleeve 1, so that when the rotating plate 32 rotates in different directions, the first extrusion groove 365 can be used to squeeze the first extrusion rod 361, so that the cutter 362 can be displaced in a fixed direction under the limit of the fixing rod 363, so that the multiple cutters 362 can be synchronously telescopically displaced, so that when the cable 8 is connected, the outer skin of the cable 8 can be cut, which is convenient for the subsequent insertion of the connecting tube 2 and the fixed clamping of the clamping assembly 37.

[0076] Furthermore, the clamping assembly 37 includes a limit rod 371, a limit block 372, a second extrusion rod 373, a positioning plate 374, a clamping block 375 and a third compression spring 376.

The third compression spring 376 is always in a compressed state, so that a stable elastic force can be provided to the positioning plate 374 through the limit block 372, so that the second extrusion rod 373 can realize the telescopic displacement of the positioning plate 374 through the second extrusion groove 377 when the rotating plate 32 rotates, so that the clamping block 375 can extrude the cut cable 8, and the cut cable 8 can be squeezed and fixed in the connecting groove opened on the connecting pipe 2 to ensure that the cable 8 will not be displaced or fall off during the connection process, thereby improving the stability and safety of the connection. The design of the clamping block 375 enables it to evenly apply pressure to the outer skin of the cable 8 cut by the cutter 362 to ensure that all parts of the cable 8 can fit tightly in the connecting groove to form a firm connection.

[0077] Specifically, the positioning mechanism 4 includes a clamping plate 41, a fixing tooth 42, a connecting rod 43, a positioning block 44, a fourth compression spring 45, a pressing plate 46 and a sliding block 47.

The triangular cross-sectional design provides a larger contact area and friction between the cable 8, which helps to more firmly fix the cable 8 and prevent it from sliding or falling off during use. The triangular shape can form a self-locking mechanism. When the cable 8 is clamped, the tip of the fixing tooth 42 will embed into the surface of the cable 8, increasing the electrical The bite force between the cable 8 and the clamping plate 41 makes it difficult for the cable 8 to disengage when subjected to external force. Elastic grooves are equidistantly provided on the outer wall of the connecting sleeve 1. One end of the connecting rod 43 passes through the elastic groove and is fixedly connected to the clamping plate 41.

The pressing plate 46 is slidably connected with the inner cavity of the positioning hole. When the positioning block 44 is inserted into the positioning hole, the pressing plate 46 can be pushed out of the sleeve 31. While the clamping plate 41 does not affect the insertion of the cable 8, the sleeve 31 can be limited so that the cutter 362 is in an extended state. At this time, the inserted cable 8 can be cut. After the cutting is completed, the positioning block 44 can be re-positioned in the positioning groove 48 by pressing the pressing plate 46, so that the sleeve 31 can be pulled and rotated to realize the switching of the state between the skin cutting component 36 and the clamping component 37. The inner wall of the positioning hole is symmetrically provided with sliding grooves. The sliding block 47 is slidably connected with the inner cavity of the sliding groove, and the sliding block 47 is fixedly connected with the extrusion plate 34.

The anti-slip pad 54 is sleeved on the outside of the plug-in rod 53 to fit the inner wall of the plug-in groove. The plug-in rod 53 can be used to position the dust cover 51 at the end of the connecting sleeve 1, so that when the clamping plate 41 is lowered to clamp the cable 8, the clamping groove and the clamping rod 52 can be clamped, so that the dust cover 51 can play a dust-proof role while not falling off easily, which is convenient for use.

[0079] Specifically, the heat exchange mechanism 6 includes a heat exchange ring 61 and a heat exchange rod 62.
