The clamping block 202 is squeezed, so that the clamping block on the clamping block 202 shrinks inwardly. One end of the copper tube terminal is fixed by the contraction of the clamping block on the clamping block 202, thereby avoiding the obstruction caused by the fixed mold when the copper tube terminal is fixed and clamped. At the same time, copper tube terminals of different sizes are clamped. When the outside of the copper tube terminal needs to be processed, the other end of the copper tube terminal is clamped by the second rotating shell 3.

The protective shell 8 drives the first rotating shell 2 to move back and forth. The distance between the first rotating shell 2 and the second rotating shell 3 is adjusted by adjusting the position of the slider 403, so as to clamp copper tube type terminal blocks of different lengths.

[0033] Specifically, a second slide groove 5 is opened on the operating table 1, and a threaded rod 502 is rotatably installed in the second slide groove 5. One end of the threaded rod 502 is axially connected to the second motor 501. The threaded rod 502 is threadedly connected to the bracket 503.

[0035] Working principle: one end of the copper tube terminal is sent into the middle of the clamping block 202 by manpower, and then the manpower rotates the push block 201. When the push block 201 rotates, it squeezes the clamping block 202 inward through the conical arc surface. The clamping block 202 is squeezed, so that the clamping block on the clamping block 202 shrinks inward. The clamping block on the clamping block 202 shrinks to fix one end of the copper tube terminal, avoiding the blocking caused by the fixed mold when the copper tube terminal is fixed and clamped. At the same time, copper tube terminals of different sizes are clamped. When the outside of the copper tube terminal needs to be processed, the second rotating shell is used. 3, the other end of the copper tube terminal is clamped, and the internal structure of the second rotating shell 3 is exactly the same as that of the first rotating shell 2, thereby improving the practicability of the device and improving the working efficiency.

By adjusting the position of the slider 403, the distance between the first rotating shell 2 and the second rotating shell 3 is adjusted, so that copper tube terminals of different lengths can be adjusted. The wire terminal is clamped, at this time, the second motor 501 drives the threaded rod 502 to rotate through the output shaft, and when the threaded rod 502 rotates, the bracket 503 is driven to reciprocate to a suitable working position through the thread transmission, and the processing equipment 504 on the bracket 503 moved to the suitable working position starts to work, and the copper tube type terminal is processed by the processing equipment 504. When it is necessary to adjust the processing position of the copper tube type terminal, the first rotating shell 2 is rotated by manpower, and the first rotating shell 2 drives the clamping block 202 to rotate, and the clamping block 202 drives the rotating shaft 205 to rotate, and the rotating shaft 205 drives the first bevel gear The disk 203 rotates, and the first bevel toothed disk 203 pushes the second bevel toothed disk 204 inward when rotating, and the second bevel toothed disk 204 is separated from the first bevel toothed disk 203, and the second bevel toothed disk 204 releases the restriction on the first bevel toothed disk 203. When the first bevel toothed disk 203 stops rotating, the return spring 206 pushes the second bevel toothed disk 204 to be in close contact with the first bevel toothed disk 203 through its own elasticity, and the second bevel toothed disk 204 is closely engaged with the teeth of the first bevel toothed disk 203 to limit the first rotating shell 2, thereby changing the processing orientation of the copper tube type terminal, thereby improving the practicality of the device.
