A stop positioning device according to claim 10, wherein a first lead screw is symmetrically disposed between the two longitudinal vertical plates, two ends of the supporting plate pass through the first lead screw, and the first clamping cylinder and the second clamping cylinder are respectively disposed at two sides of the supporting plate.

12. A stop-and-position device according to claim 9, further comprising a lifting mechanism capable of adjusting the height of the clamping assembly in the longitudinal direction.

13. A blocking and positioning device according to claim 12, wherein the lifting mechanism comprises slide rails symmetrically arranged on the inner side of the longitudinal vertical plate, a first slide block arranged on the slide rails, and a second lead screw arranged between the two slide rails, wherein an adjusting hand wheel is arranged at the upper end of the second lead screw, a second slide block is further arranged on the second lead screw, the first slide block and the second slide block are both connected with the installation groove body, and the second slide block can move along the longitudinal direction of the second lead screw by rotating the adjusting hand wheel, so as to drive the installation groove body to move along the longitudinal direction of the slide rails.

14. A stop positioning device according to claim 9, further comprising a first limit guide and a second limit guide symmetrically disposed in said buffer area, wherein a width between said first limit guide and said second limit guide is equal to a width of said positioning element to be stopped.
