[0019] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0020] like Figure 1 and Figure 6As shown, the utility model can be implemented through the following embodiments: a firing force adjustment structure of a nail gun, comprising a nail gun body 1, a magazine structure 2 and a firing piece 9, a trigger 11 is provided on the nail gun body 1, a slide rod 21 is provided on the magazine structure 2, an adjustment mechanism 3 is provided between the trigger 11 and the slide rod 21, the adjustment mechanism 3 comprises a slide rod guide 31, a slide groove 311 is provided on the slide rod guide 31, a sliding plate 4 is installed in the slide groove 311, a fixed plate 41 is provided on the sliding plate 4, an adjusting wheel 5 is installed on the fixed plate 41, an adjusting screw 6 is provided between the adjusting wheel 5 and the fixed plate 41, the adjusting screw 6 is fixed on the slide rod 21, a contact plate 7 is provided in the trigger 11, an abutment block 42 is provided on the sliding plate 4, and the abutment block 42 contacts the contact plate 7.

[0021] The adjusting wheel 5 in the rotating adjusting mechanism 3 rotates on the adjusting screw 6 and realizes linear motion, so that the adjusting wheel 5 pushes the sliding plate 4 to move on the slide rod guide 31 through the fixed plate 41, and the moving sliding plate 4 drives the abutment block 42 to push the contact plate 7, so that when the trigger 11 is pulled, the contact plate 7 and the firing member 9 are moved, so that the stroke of the firing member 9 changes, thereby changing the firing force; the sliding plate 4 provides a guiding function to prevent the slide rod 21 from being offset during adjustment, which causes the firing force to deviate.

[0022] like Figures 2 to 4 As shown, a clearance groove 312 is provided on the slide bar guide 31. The clearance groove 312 provides a moving space for the sliding plate 4 and limits the range of variation of the firing force.

[0023] like Figure 2 and Figure 3 As shown, a short rod 111 is provided in the trigger 11, and the contact plate 7 is rotatably connected to the short rod 111. As the abutment block 42 comes into contact with the contact plate 7, as the abutment block 42 moves, the contact plate 7 will rotate around the short rod 111 as the center of the circle, thereby changing the distance between the contact plate 7 and the firing member 9.

[0024] like Figure 2 and Figure 3 As shown, the adjusting screw 6 is provided with a groove 1 61, in which a C-shaped retaining spring 62 is installed. The C-shaped retaining spring 62 is installed in the groove 1 61 to limit the displacement of the sliding plate 4, preventing the adjusting wheel 5 from excessively rotating and causing the adjusting wheel 5 to pull the sliding plate 4 away from the adjusting screw 6, thereby ensuring that the firing function of the nail gun body 1 can function normally.

[0025] like Figure 2 、 Figure 3 、 Figure 5 and Figure 6As shown, a boss 51 is formed on the left side of the adjusting wheel 5, a second groove 511 is formed on the boss 51, and a protrusion 411 is provided on the fixing plate 41, and the protrusion 411 contacts the boss 51. When the adjusting wheel 5 rotates, the protrusion 411 passes through the second groove 511, causing the adjusting wheel 5 to vibrate slightly during rotation. The vibration serves to remind the operator of the force scale to be adjusted, making it easier for the operator to adjust the firing force of the nail gun.

[0026] like Figures 1 to 3 As shown, a spring latch 8 is installed between the slide bar guide 31 and the nail gun body 1. The slide bar guide 31 is connected to the nail gun body 1 via the spring latch 8. When the trigger 11 is pulled, the contact plate 7 applies pressure to the firing member 9 using the short rod 111 and the abutment block 42 as a fulcrum. When the nail gun body 1 is fired, the slide bar 21 rapidly reciprocates, thereby driving the sliding plate 4 to reciprocate. At this time, the contact plate 7 contacts the slide bar guide 31. When the slide bar 21 is reset, the sliding plate 4 impacts the slide bar guide 31 and the contact plate 7, causing the slide bar guide 31 to deform. The spring latch 8 allows the slide bar guide 31 to rotate and absorbs the impact, thereby increasing the service life of the adjustment mechanism 3.

[0027] The working principle of the present invention is as follows: put the nail into the magazine structure 2, rotate the adjusting wheel 5, so that the adjusting wheel 5 drives the sliding plate 4 to move left, the sliding plate 4 drives the abutment block 42 to move left, the abutment block 42 contacts the contact plate 7, so that the contact plate 7 rotates counterclockwise with the short rod 111 as the center, the contact plate 7 touches the firing piece 9, thereby shortening the stroke of the firing piece 9, and pulling the trigger 11, so that the nail gun body 1 shoots out a nail with a weaker firing force; on the contrary, the adjusting wheel 5 drives the sliding plate 4 to move right, the sliding plate 4 drives the abutment block 42 to move right, the abutment block 42 moves away from the contact plate 7, so that the contact plate 7 rotates counterclockwise with the short rod 111 as the center, the contact plate 7 moves away from the firing piece 9, the stroke of the firing piece 9 increases, and when the trigger 11 is pulled, the nail gun body 1 shoots out a nail with a strong firing force.

[0028] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.

[0029] Although various terms are used in this document, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the present invention; interpreting them as any additional restrictions is contrary to the spirit of the present invention.
