The second sliding groove 50 is composed of a first section 500, a second section 501 and a third section 502, the distance between the first pressing part 510 and the second pressing part 511 is shortened in the process that the second sliding block 51 enters the second section 501 from the first section 500, and the distance between the first pressing part 510 and the second pressing part 511 is lengthened in the process that the second sliding block 51 enters the third section 502 from the second section 501.
Specifically, the deformation bar 312 is deformed after being extruded by the probe rod 4, and the deformed deformation bar 312 needs to maintain the deformed structure, so that when the deformed position on the deformation bar 312 passes through the probe rod 4, the second slider 51 reaches the junction of the first section 500 and the second section 501, the junction extrudes the first pressing portion 510 and the second pressing portion 511 of the second slider 51, the elastic force of the second elastic member is increased, the distance between the first pressing portion 510 and the second pressing portion 511 is gradually shortened, the extrusion force of the first brace 52 is gradually increased, and thus the deformation of the deformation bar 312 drives the movement of the first brace 52 between the first pressing portion 510 and the second pressing portion 511 to be blocked more and more, and finally, when the second slider 51 reaches the second section 501, the first brace 52 is positioned between the first pressing portion 510 and the second pressing portion 511, thereby positioning the deformed structure of the deformation bar 312 is realized.

After the spraying operation is finished, the conveying unit 2 gradually leaves the second section 111 with the workpiece, the second supporting rod 322 gradually moves from the linear part in the third sliding groove 320 to the curved part, the second supporting rod 322 moves circumferentially along the center of the curved part, the second supporting rod can gradually get rid of the conveying unit 2, in the process, the second sliding block 51 gradually enters the third section 502 from the second section 501, the extrusion action of the first pressing part 510 and the second pressing part 511 gradually disappears, the extrusion action of the first pressing part and the second pressing part on the first supporting rod 52 gradually loses under the action of the resilience force of the second elastic part, the deformed deformation bar 312 gradually returns to the linear structure under the action of the resilience force of the first elastic part after the deformation bar 312 loses position, the second sliding block 51 is also driven to return to the initial position in the second sliding groove 50, and then the spraying operation on the next workpiece can be started.
