[0029] The specific usage and function of this embodiment are as follows:

[0030] In this utility model, when... Figure 1As shown, when the device body 1 is in use, the bearing frame seat 2 is fixed to the workbench with bolts. The cable and connector are placed inside the pressure welding groove of the fixed pressure welding block 3. The bearing shaft 5 is rotated by rotating the handle rod 6. The rotation of the bearing shaft 5 drives the main bevel gear 7 to rotate synchronously, so that the main bevel gear 7 rotates and meshes with the driven bevel gear 9. In this way, the large gear drives the small gear, and the speed of the small gear will increase. This is the principle of gear transmission ratio, thereby realizing the rotation speed change. The driven bevel gear 9 rotates through meshing, and the driven bevel gear 9 drives the pressure application. The pressure applying rod 8 rotates synchronously, causing it to engage with the threaded engagement of the lifting pressure block 10. This causes the lifting pressure block 10 to descend via the threaded engagement. Note that as the rotational speed of the bevel gear 9 increases, the rotational speed of the pressure applying rod 8 and the threaded engagement speed of the lifting pressure block 10 also increase. This increases the lifting speed of the lifting pressure block 10, which in turn drives the moving welding block 11 to descend synchronously. Thus, pressure is applied to the cable and connector sections via the moving welding block 11 and the fixed welding block 3, achieving welding of the cable and connector sections. Figure 1 As shown, when the fixed welding block 3 is disassembled, the assembly fixing post 4 is rotated by a tool to engage with the thread of the fixed welding block 3, so that the assembly fixing post 4 descends and disengages from the threaded blind hole of the fixed welding block 3 through thread engagement, and the fixed welding block 3 is moved forward or backward to disengage from the dovetail groove of the bearing frame seat 2, thereby realizing the disassembly of the fixed welding block 3 and solving the problem of not being able to replace it according to the cable and connector model.

[0031] Example 2: Unlike Example 1, the regular hexagonal groove of the assembly fixing column 4 can also be set as a regular heptagonal groove. This makes it necessary to use a special tool that cooperates with the regular heptagonal groove to rotate the assembly fixing column 4, thus preventing non-workers from rotating and disassembling the assembly fixing column 4.

[0032] Example 3: The difference from Example 1 is that the regular hexagonal prism of the assembly locking pin 12 can also be set as a regular heptagonal prism, so that the assembly locking pin 12 can only be rotated by a special tool that cooperates with the regular heptagonal prism, thus preventing non-workers from rotating and disassembling the assembly locking pin 12.
