When the driving motor drives the first screw rod 12 to rotate, the first screw rod is provided with the first bevel gear 13. The rotation of the first bevel gear 13 becomes the driving force source of the whole transmission mechanism. The first bevel gear 13 drives the third bevel gear 15 to rotate through gear engagement, ensuring that the force is stably transmitted from the rotation of the first screw rod to the connecting rod. The third bevel gear 15 is connected with the fourth bevel gear 16 through the connecting rod 17.

The structure of the fixed frame 321 can be a frame with certain height and strength, which can support and stabilize the cable. It is installed above the fixed plate 31 and used for supporting and fixing the cable. The top of the fixed frame 321 is provided with a hole 322, and the size of the hole is designed to be suitable for the threaded connection of the hand screw bolt. The hole 322 is internally provided with threads, which facilitates the insertion and tightening of the hand screw bolt. The hand screw bolt 323 is connected to the hole 322 through threads, which can be tightened or loosened as needed. After the cable is placed in the groove of the fixed frame, the hand screw bolt can be screwed into the hole and tightened, and the cable is pressed tightly on the fixed frame by the fixed pressing plate, so that the cable does not move during the fusion process.

[0030] When the cable needs to be fixed, the cable is placed in the fixed frame 321, and the hand screw bolt 323 is tightened to manually press the cable tightly on the fixed frame. The design of the hand screw bolt makes the operation simple and does not require additional tools, which facilitates quick installation and removal of the cable. The hand screw bolt design is convenient for manual operation and is suitable for working environment that requires frequent installation, adjustment or replacement of cables. The threaded connection can ensure that the cable is firmly fixed and prevent position deviation due to vibration or external force during the fusion process. The hand screw bolt can be flexibly adjusted according to the thickness of different cables, and is suitable for cables of various specifications.

The receiving plate 27 is fixed on the support shell 34.

[0032] The support seat 33 is fixed on the surface of the base 1 to provide stable support for the entire welding device, ensuring that it can withstand the pressure and vibration of the welding device during the welding process, making the device structure more stable. The support seat 33 is fixed with the support shell 34, which is sleeved outside the lifting threaded sleeve 23 to form a protection and guide structure for the lifting threaded sleeve. In this way, the support shell can effectively limit the movement trajectory of the threaded sleeve during lifting, preventing deviation or shaking caused by external forces.

[0033] The inner wall of the support shell 34 is provided with a sliding rail 35, and the sliding block 36 on the lifting threaded sleeve 23 is connected with the sliding rail 35 in a sliding manner.

The receiving plate 27 is fixed on the support shell 34 and located below the heating plate 26. In this way, the cable can be stably received on the receiving plate during pressing and heating, ensuring accurate positioning during welding.

[0034] When the driving motor drives the second screw 22 to rotate, the lifting threaded sleeve 23 moves vertically under the thread drive. The lifting threaded sleeve is guided by the sliding block 36 in the sliding rail 35 to ensure that it does not tilt or deviate during movement. Through the stable support of the support shell 34 and the receiving plate 27, the cable is accurately positioned and stably welded.

[0035] The design of the sliding rail and the sliding block ensures the smooth lifting of the lifting threaded sleeve, preventing displacement during pressing and improving the welding precision. The support seat and the support shell provide a solid support for the welding mechanism, so that the entire device remains stable during operation. The sliding rail and the sliding block structure enable the lifting threaded sleeve to slide smoothly, which helps to control the accurate pressing of the pressing plate. The stability and guidance precision of the welding device are enhanced, providing reliable support and precise pressure control for cable welding.
