[0046] Embodiment 3

[0047] Referring to FIGS. 1-5, this is a third embodiment based on the first and second embodiments of the application, which includes a reset unit 500, including a reset assembly 501 arranged on the mounting frame 101, and a misalignment assembly 502 arranged on the mounting shell 103.

[0048] Further, the reset assembly 501 includes a second connecting belt 501a arranged on one side of the mounting shell 103, a winding disc 501b arranged on the mounting frame 101, a motor 501c arranged on the mounting frame 101, a trigger switch 501d arranged on the mounting frame 101, a connecting wheel 501e arranged on the motor 501c and the winding disc 501b respectively, and a second transmission belt 501f arranged on the two connecting wheels 501e.

The sliding rod 502e has irregular grooves, so that the extrusion block 502f is always vertical, and the extrusion block 502f is provided with an inclined surface.

[0051] In use, when the detection is about to contact, the mounting shell 103 gradually approaches one of the mounting frames 101, the extrusion block 502f is extruded and cannot continue to slide, and the mounting shell 103 is also subjected to tension. The bottom edge of the connecting frame 502h will slide along the inclined surface of the extrusion block 502f, while pulling the mounting shell 103 to slide downward. The distance between the fixed rod 502a and the positioning rod 102 is fixed, so the mounting shell 103 will move downward, while the positioning rod 102 will slide upward in the limiting slot 502d relative to the mounting shell 103, until the extrusion block 502f is completely inserted into the connecting frame 502h, and the clamping block 403a is separated from the groove 403b. Under the action of the tension spring 502c, the extrusion block 502f will be connected with the connecting frame 502h, while the mounting shell 103 touches the trigger switch 501d, starts the motor 501c, and drives the winding disc 501b to wind the second connecting belt 501a. The mounting shell 103 is pulled to reset. When the mounting shell 103 is about to completely reset, the push plate 502g will be inserted into the connecting frame 502h, extruding the extrusion block 502f out of the connecting frame 502h. Finally, the mounting shell 103 touches the trigger switch 501d to turn off the motor 501c, so that the mounting shell 103 is reset.

[0052] In summary, the motor 501c is turned on and off by the installation shell 103 hitting two trigger switches 501d to drive the installation shell 103 to reset. In the resetting process, the pressing block 502f will press down the installation shell 103, so that the installation shell 103 and the positioning rod 102 are relatively displaced, the positioning unit 400 and the positioning rod 102 are separated, and then the resetting is completed and the connection is reestablished. The whole process does not need to be intervened by the operating system and manually, and the automatic repeated detection of the detection area by the device is realized.
