[0021] In the present invention, the heat shrinkable shell 3 can shrink by heat.

[0022] The working principle of this embodiment is as follows: when the cable joint needs to be tinned, first open the plug 4, inject water into the heating shell 2 through the through hole on the periphery of the heating shell 2, and then reinstall the plug 4 to keep the heating shell 2 in a relatively closed state. The self-heating material starts to work and generates heat. The heat accumulates in the cavity of the heating shell 2 and is transferred outward. Since the tin layer 1 is installed on the inner periphery of the heating shell 2, the tin layer 1 will absorb the heat. As the temperature rises, the tin layer 1 gradually melts, and the molten tin liquid can evenly cover the cable joint, completing the tinning operation and ensuring good conductivity and stability of the cable joint. The heat shrink shell 3 is installed on the periphery of the heating shell 2. During the tinning process, the heat shrink shell 3 can shrink due to the heat and wrap the cable joint.

[0023] In the present invention, the self-heating material can be heated to 200° C. and can melt the tin layer 1 .

[0029] like Figure 2 and Figure 4As shown, the cable fixing assembly includes a clamping box 11, which is installed at the end of a movable assembly. A rotating shaft 28 and a rotating shaft 3 are arranged in the clamping box 11. The end of the rotating shaft 28 passes through the end of the clamping box 11 and is installed with a turntable 12. The end of the rotating shaft 3 passes through the end of the clamping box 11 and is installed with a turntable 2 13. The outer peripheries of the rotating shaft 28 and the rotating shaft 3 are respectively installed with a gear 2 27 and a gear 1 26. The gear 1 26 is meshed with the gear 2 27. The sides of the turntables 12 and 13 are installed with movable fixing assemblies. The end of the rotating shaft 2 28 away from the turntable 12 passes through the end of the clamping box 11 and is installed with a rotating member 3.

[0030] like Figure 2 As shown, the movable fixed assembly includes a connecting shaft 1 and a connecting shaft 2, the connecting shaft 1 is installed on the side of the turntable 12, the connecting shaft 2 is installed on the side of the turntable 2 13, the end of the connecting shaft 1 is installed with a connecting piece 3 16, the side of the connecting piece 3 16 close to the connecting shaft 1 is provided with a groove 1, the groove 1 is installed with a connecting piece 14, the end of the connecting shaft 2 is installed with a connecting piece 2 15, the connecting piece 2 15 is slidably connected to the connecting piece 1 14, the side of the connecting piece 2 15 is installed with an arc-shaped clamping piece 17, the side of the connecting piece 14 is installed with an arc-shaped clamping piece 2 18, and the cable is located between the arc-shaped clamping piece 17 and the arc-shaped clamping piece 2 18.

[0031] like Figure 3 As shown, a spring is installed between the side of the adjusting member 22 and the interior of the adjusting box 7, and the guide shaft 21 is located inside the spring.

[0032] like Figure 2 and Figure 3 As shown, the movable component includes a fixed part 9 and a sliding part 10. The fixed part 9 is installed at the end of the movable part 8. A sliding groove is provided on the side of the fixed part 9. The sliding part 10 is located in the sliding groove. The end of the sliding part 10 is fixedly connected to the clamping box 11. A through hole four is provided above the fixed part 9. A plurality of through holes five are provided above the sliding part 10. A pin shaft is provided between the through hole four and the corresponding through hole five.

[0033] The working principle of this embodiment is as follows: first, the self-heating tinning device is placed in the clamping assembly. The rotating member 1 20 is rotated to drive the bidirectional screw 19 to rotate. Since the bidirectional screw 19 is equipped with two clamping members 5, the two clamping members 5 will move toward or away from each other along the bidirectional screw 19 when the screw rotates, thereby clamping or loosening the self-heating tinning device, ensuring that the self-heating tinning device is firmly fixed in the U-shaped frame 6.

[0034] When the cable needs to be fixed, the rotating shaft 25 is driven to rotate by operating the rotating part 2, and the driving gear on the outer periphery of the rotating shaft 25 rotates accordingly, and the driving gear cooperates with the chain. Since one end of the chain is connected to the adjusting part 1 22, and the other end is connected to the fixing part 24 under the adjusting part 23, the movement of the chain drives the adjusting part 1 22 and the adjusting part 2 23 to slide in relative or opposite directions on the guide shaft 21. The guide shaft 21 plays a guiding role to ensure the stability of the movement of the adjusting part 1 22 and the adjusting part 2 23. At the same time, the spring between the side of the adjusting part 1 22 and the inside of the adjusting box 7 plays a role of buffering and auxiliary reset.

[0035] The movement of adjusting member 1 22 and adjusting member 2 23 drives the moving member 8 installed on their sides to move in the through hole 3 of the adjusting box 7, and the movable component at the end of the moving member 8 moves accordingly. In the movable component, the fixed member 1 9 is installed at the end of the moving member 8, and the sliding member 10 slides in the slide groove on the side of the fixed member 1 9. By inserting a pin between the through hole 4 and the corresponding through hole 5, the position of the sliding member 10 can be fixed, thereby adjusting the position of the clamping box 11.

[0036] When the sliding member 10 drives the clamping box 11 to move to the appropriate position, the rotating member 3 is rotated, which drives the rotating shaft 2 28 to rotate, and the gear 2 27 on the outer periphery of the rotating shaft 2 28 rotates accordingly. Since the gear 1 26 and the gear 2 27 are meshed, the gear 1 26 also rotates, thereby driving the rotating shaft 3 to rotate, and the turntable 1 12 and the turntable 2 13 connected to the rotating shaft 2 28 and the rotating shaft 3 also rotate accordingly. The connecting shaft 1 and the connecting shaft 2 respectively drive the connecting member 3 16, the connecting member 1 14, and the connecting member 2 15 to move, so that the arc clamping member 1 17 and the arc clamping member 2 18 move relative to or away from each other, thereby clamping or loosening the cable between them, thereby achieving stable clamping of the cable.
