The holding rod 10 corresponds to the fixed clamping rod 6 through the sliding mouth at the bottom of the connecting compartment 5 and is slidably connected with the cable 3. A plurality of sockets 11 are provided on the top of the connecting compartment 5. The top of the connecting compartment 5 is plugged into the sockets 11 through a telescopic buckle mechanism. The cable 3 is clamped and fixed by means of the provided movable clamping rod 10 and the fixed clamping rod 6. The movable clamping rod 10 and the fixed clamping rod 6 are driven to rotate through the connecting compartment 5 by means of the provided bearing 4, so as to wind the cable 3. The cable 3 is fixed after winding by means of the provided telescopic buckle mechanism, thereby solving the problem of poor fixing and clamping force of the lap joint on the high-voltage cable after long-term use.

[0028] In order to facilitate the fixing of the cable 3 after winding, as shown in FIG. Figure 1-4As shown, the telescopic buckle mechanism includes a square telescopic rod 12, a first rotating rod 13 and a latch 14. The square telescopic rod 12 is fixedly connected to the top of the connecting bin 5. The top of the square telescopic rod 12 is fixedly connected to the first rotating rod 13. The side wall of the first rotating rod 13 is fixedly connected to the latch 14. One end of the latch 14 is plugged into the socket 11. By using the set square telescopic rod 12, after the rotating rod 13 is operated to rotate to make the cable in the cavity of the bottom connecting bin 5 entangled, the set latch 14 is plugged into the socket 11 to fix the connecting bin 5.

[0029] In order to facilitate fixing one end of the cable 3 to reduce the tension, Figure 1-3 As shown, the fixing mechanism includes a bolt 15 and an arc-shaped top plate 16.

[0033] Working principle:

[0034] When in use, the two cables 3 are inserted into the cavity of the bin body 1 from the connecting ports 2 at both ends, and the manually operated twist knob 9 is rotated to rotate the threaded rod 7 to drive the movable clamping rod 10 and the fixed clamping rod 6 at the bottom of the threaded seat 8 to tighten and clamp the cable 3. The bearing 4 is convenient for manually driving the connecting bin 5 to rotate, so that the movable clamping rod 10 and the fixed clamping rod in the cavity of the connecting bin 5 drive the cable 3 to be wound, and the connecting bin 5 is fixed by plugging with the socket 11 after winding. The second rotating rod 17 on the side wall of the connecting ports 2 at both ends is manually rotated to drive the bolt 15 to rotate, so that the arc-shaped top plate 16 at the bottom of the bolt 15 presses down and fixes the cables 3 at both ends, thereby reducing the tension generated when the cable 3 is shaken or pulled, thereby solving the problem that the fixing and clamping force of the lap joint on the high-voltage cable is poor after long-term use.

[0035] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
