Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

Example one

As shown in the attached drawings 1-6, a blank shooting prevention mechanism of a nailing machine comprises a shell 1, wherein a gun head 2 is arranged on the inner side of the front part of the shell 1, a trigger 4 is hinged in front of a handle 3 of the shell 1, a trigger pressure spring assembly 5 is arranged behind the trigger 4, the trigger pressure spring assembly 5 is used for resetting the trigger 4, a gun cover 6 is arranged above the gun head 2, a fixed cartridge clip 7 is arranged below the gun head 2, a movable cartridge clip 8 is arranged in the fixed cartridge clip 7, a guide block 9 is embedded in a groove 21 below the gun head 2, a protrusion 92 is arranged on one side of the guide block 9, the protrusion 92 is embedded in a top head 10 above the movable cartridge clip 8 in a clamping manner, a spring seat 11 in the movable cartridge clip 8 is connected below the top head 10, a slot 91 is arranged in the guide block 9, and the slot 91 is used for inserting and embedding the front end of a limit block 12, the limiting block 12 is provided with a limiting groove 121, the lower part of the limiting groove 121 is aligned to the spring seat 11, and the rear end part of the limiting block 12 is bent downwards and then is abutted against the rear part of the trigger 4.

The limiting block 12 comprises a vertical inserting part 122 inserted into the guide block slot 91, the middle part of the vertical inserting part 122 is provided with a limiting groove 121, the rear part of the vertical inserting part 122 is connected with a horizontal part 123, the horizontal part 123 passes through two limiting columns 124 on the shell 1 and then bends downwards to form a bending part 125, and the bending part 125 is inserted into the rear part of the trigger 4 and used for limiting the trigger 4 to be pressed after nails in the elastic clamp are less than a specified number.

The bent part 125 of the limiting block 12 is located between the trigger 4 and the trigger compression spring assembly 5.

As shown in the attached figure 1, at this time, when the gun nail 13 is in a sufficient state, the gun nail downwardly presses the guide block 9, the top 10 and the spring seat 11, so that the spring seat 11 is separated from the limit groove 121 of the limit block 12, and the trigger 4 can be arbitrarily buckled.

As shown in attached figures 2 and 3, when the gun nails 13 are in a small quantity or completely used, the gun nails 13 lose the compression on the guide block 9, the top 10 and the spring seat 11, so that the spring seat 11 moves upwards and is gradually inserted into the limiting groove 121 of the limiting block 12, and the front-back movement (K direction) of the spring seat is limited, so that the trigger 4 is completely locked and cannot be buckled, and the aim of preventing the hollow nails is fulfilled.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
