Description

Technical Field

[0001] The utility model relates to the technical field of automatic assembly equipment, in particular to a front screw locking mechanism. Background Art

[0002] Nail guns are mostly used in construction. Currently, one of the most widely used nail guns is an electric nail gun that uses a lithium battery. This type of nail gun uses a driving motor and a corresponding transmission structure to push the piston, and then the piston compresses the power supply spring or compressed gas to store energy. When shooting nails, the power supply spring or air pressure drives the piston to move, and then drives the firing pin installed on the piston to impact and shoot the nails to achieve nailing. The mouth part of the nail gun is provided with a magazine mechanism for storing nails. The nails are stored in the magazine body. Usually, a nail groove and a nail guide groove are set at the gun mouth. The nails are sent out from the magazine body through the nail groove and are struck out by the firing pin along the nail guide groove. Figure 1 As shown, during the production and assembly process of the magazine, it is necessary to use screws to fix the Z-shaped end cover to the semi-finished magazine. Currently, the screws are generally assembled manually. During the screw locking process, the end cover needs to be pressed manually, otherwise the spring at the end will push it away, so the assembly efficiency is low. Utility Model Content
