[0006] By adopting the above technical scheme, the position of the pipe fitting is detected by the first optical distance sensor and the second optical distance sensor, and the position of the pipe fitting after limiting is adjusted by controlling the third telescopic cylinder.

[0007] Preferably, the first optical distance sensor and the second optical distance sensor are electrically connected with the third telescopic cylinder.

[0008] By adopting the technical scheme, the first optical distance sensor is located on the left side, and the second optical distance sensor is located on the right side; the detection length of the first optical distance sensor and the second optical distance sensor is the maximum distance value between the lower extrusion block; when the first optical distance sensor and the second optical distance sensor can both detect the length, it is indicated that the pipe placed on the lower extrusion block blocks the first optical distance sensor and the second optical distance sensor; at this time, the third telescopic cylinder is automatically shortened until the first optical distance sensor cannot detect the length value, indicating that one end of the pipe is located at the first optical distance sensor; when the first optical distance sensor and the second optical distance sensor cannot both detect the length, it is indicated that the pipe on the lower extrusion block is located on the right side of the second optical distance sensor; at this time, the third telescopic cylinder is automatically elongated until the length value is detected; after the pipe is placed on the lower extrusion block, the position can be automatically adjusted so that the pipe joint is located at the middle part of the first optical distance sensor and the second optical distance sensor.

The position of the support frame is adjusted by the third telescopic cylinder to keep the pipe on the lower extrusion block. The position can be automatically adjusted so that the pipe joint is located in the middle of the first optical distance sensor and the second optical distance sensor. This achieves the effect of automatically adjusting the length of the protruding end of the pipe, so that the assembled joint and pipe are tightly connected.

[0021] 2. This application allows multiple connectors to be placed into the connector box sequentially. The guide block makes it easier to place the connectors into the connector box. By rotating the knob, the threaded rod is rotated, and the position of the limit rod is adjusted so that the connectors can be better placed inside the connector box.
