Description of the embodiments

The following are specific embodiments of the present utility model and the technical solutions of the present utility model will be further described with reference to the accompanying drawings, but the present utility model is not limited to these embodiments.

As shown in fig. 1 to 5, the present utility model can be realized by the following embodiments: an idle-driving prevention structure of a nail gun comprises a guide plate 1, a movable nail box 2 and a fixed nail box 3, wherein a nail groove 11 for discharging nails is formed in the guide plate 1, and the movable nail box 2 and the fixed nail box 3 for containing nails of the gun are arranged below the guide plate 1.

The movable nail box 2 is provided with a mounting groove 21, a compression spring 4 is arranged in the mounting groove 21, a spring bracket 5 and a stop block 6 are arranged on the compression spring 4, a baffle 61 is arranged at the upper end of the stop block 6, a through groove 62 is formed in the middle section of the stop block 6, the baffle 61 stretches into the nail groove 11 and is used for blocking the movement of a firing pin, a nail pushing block 7 is arranged on the fixed magazine, a plugboard 71 is arranged on the nail pushing block 7, the plugboard 71 is inserted into the spring bracket 5 and the stop block 6, the nail pushing block 7 is used for feeding nails into the nail groove 11 under the action of the compression spring 4 after the nail gun is shot, normal firing of the nail gun is ensured, and meanwhile, the stop block 6 and the spring bracket 5 connected with the nail pushing block 7 through the plugboard 71 are driven to rise by the nail pushing block 7.

Further explaining, as shown in fig. 5, the guide plate 1 is provided with a avoiding groove 12 into which the baffle plate 61 extends, and the avoiding groove 12 is arranged so that the baffle plate 61 can smoothly extend into the nail groove 11, and the baffle plate 61 is prevented when the nail gun is in idle driving.

As shown in fig. 2 and 4, the middle section of the stopper 6 is provided with a through groove 62, and a plugboard 71 is inserted into the through groove 62, and the length and width of the through groove 62 are larger than those of the plugboard 71. Because the length of the stop block 6 is larger than that of the spring bracket 5, and the length and the width of the through groove 62 are larger than those of the inserting plate 71, the stop block 6 and the inserting plate 71 can slide relatively in the axial direction, and when the nail pushing block 7 pushes the gun nail, the stop block 6 slides downwards, so that the gun nail can be pushed stably; after the nail box is emptied, the nail pushing block 7 is blocked by the nail groove 11, and the stop block 6 stretches into the nail groove 11 from the avoidance hole due to the tension of the compression spring 4, so that the idle-free punching prevention effect is achieved.

As shown in fig. 3, the insert plate 71 is provided with a friction protrusion 711, the friction protrusion 711 contacts with the inner wall of the through groove 62, and the friction protrusion 711 increases the friction force between the insert plate 71 and the through groove 62, preventing the insert plate 71 from moving randomly in the through groove 62, so that the gun nail cannot be accurately fed into the nail groove 11.

As shown in fig. 2, the outer wall of the mounting groove 21 is provided with an observation window 211, so that a user can observe the condition in the fixed nail box 3 through the observation window 211, thereby being convenient for the user to judge the time for filling the gun nails and being convenient for the user to work.

As shown in fig. 1, 4 and 5, the baffle 61 is provided with a chamfer 611 on a surface facing the striker, and since the baffle 61 is located at a position below the staple groove 11, the baffle will touch the lower part of the striker when the striker moves, and the chamfer 611 can be provided to disperse the striker to bring collision force, and prevent the corner and burr from damaging the striker under high-speed collision with the striker, thereby reducing the service life of the striker.
