Description

Technical Field

[0001] The utility model relates to the technical field of screw locking, in particular to a screw locking nozzle structure. Background Art

[0002] The suction holes of existing screw locking nozzles are generally regular polygonal holes (such as regular hexagonal holes). When negative pressure is formed inside the nozzle and the nail is sucked through the nozzle, the suction force provided by the regular polygonal hole is relatively small, which makes it easy for the screw to fall off during the suction process, and the screw is sucked crookedly, which in turn causes the screw to float, rot, or be roughened during the locking process, resulting in defective products. Summary of the Invention

[0016] (2) In the present invention, by setting the positioning holes, the screws are positioned through the positioning holes and then adsorbed on the adsorption surface, which further avoids the phenomenon of the screws being adsorbed and tilted, and further improves the stability of the processing.
