Detailed Implementation

[0030] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] See Figures 1-10 This utility model provides a technical solution:

[0032] A nail gun's nail penetration depth adjustment device includes a fixed tube 1, a movable tube 2, an adjusting rod 3, a transmission slider 4, a piston rod 5, and a guide rail 6. The movable tube 2 is slidably disposed within the fixed tube 1, and the piston rod 5 is slidably disposed within the movable tube 2. The fixed tube 1 has a slot 7, and the end of the guide rail 6 is inserted into the slot 7 and engages with the movable tube 2. A guide plate 8 and a stabilizing plate 9 are fixedly disposed on the fixed tube 1. The transmission slider 4 is slidably disposed on the fixed tube 1 and positioned between the guide plate 8 and the stabilizing plate 9. The guide plate 8 has a guide hole 10 that engages with the adjusting rod 3. The adjusting rod 3 is parallel to the fixed tube 1, and one end of the adjusting rod 3 is threadedly engaged with the transmission slider 4. The movable tube 2 has an adjusting block 11 that engages with the other end of the adjusting rod 3, and the fixed tube 1 has a guide groove 12 that engages with the adjusting block 11. The fixed tube 1, movable tube 2, and piston rod 5 all have circular cross-sections and are coaxially arranged. The fixed tube 1, guide plate 8, and stabilizing plate 9 are integrally formed. Figure 1 and Figure 2 This is a diagram showing the connection structure of a gas nail gun. Figure 3 and Figure 4 This diagram illustrates the structure of the piston rod in a gas nail gun at different positions within the moving tube. Figure 5 a and b are structural diagrams of the replaceable movable tube 2 on the gas nail gun; Figure 6 and Figure 7 This is a diagram showing the connection structure of an electric nail gun. Figure 8 and Figure 9 This is a schematic diagram showing the piston rod in different positions within the movable tube of an electric nail gun. Figure 10 Figures c, d, and e show the structure of the replaceable movable tube 2 on an electric nail gun. Both gas nail guns and electric nail guns use a structure consisting of a fixed tube 1, a movable tube 2, an adjusting rod 3, a transmission slider 4, a piston rod 5, and a guide rail 6. The fixed tube 1 is used to mount the movable tube 2, which is movable within the fixed tube 1. Because the adjusting block 11 engages with the guide groove 12, the movable tube 2 cannot rotate within the fixed tube 1. The movable tube 2 houses the piston rod 5, which pushes the nail in the movable tube 2 to achieve fixation between the two objects. The transmission slider 4 can slide between the guide plate 8 and the stabilizing plate 9, and can rest against the stabilizing plate 9. One end of the adjusting rod 3 rests against the adjusting block 11 on the movable tube 2, and the other end of the adjusting rod 3 is threadedly engaged with the transmission slider 4, thereby adjusting the relative position between the fixed tube 1 and the movable tube 2. The piston rod 5 is located inside a piston cylinder, which is fixedly connected to the stabilizing plate 9; therefore, the extension length of the piston rod 5 remains constant within the movable tube 2. The movable tube 2 and the adjusting block 11 are integrally formed. The guide plate 8 is used to guide the movement of the adjusting rod 3. The fixed tube 1, movable tube 2, adjusting rod 3 and piston rod 5 are arranged parallel to each other. The guide rail 6 is inserted into the fixed tube 1 to limit the movement of the movable tube 2 and prevent the movable tube 2 from detaching from the fixed tube 1.

[0033] In some embodiments, a limiting groove 13 is provided on the threaded end of the adjusting rod 3, and a limiting spring 14 that cooperates with the limiting groove 13 is provided in the limiting groove 13. The transmission slider 4 is disposed between the limiting spring 14 and the guide plate 8. The limiting groove 13 is provided to install the limiting spring 14, and the limiting spring 14 limits the transmission slider 4 to prevent the transmission slider 4 from separating from the adjusting rod 3.

[0034] In some embodiments, the guide plate 8 is provided with a through anti-rotation hole 15, and an anti-rotation member 16 is provided in the anti-rotation hole 15. The side wall of the adjusting rod 3 is provided with a plurality of anti-rotation grooves 17 that cooperate with the anti-rotation member 16, and the anti-rotation grooves 17 are arranged parallel to the adjusting rod 3. The anti-rotation member 16 is a rigid ball, and the guide plate 8 is provided with an anti-disengagement groove 18 that cooperates with the anti-rotation hole 15. An anti-disengagement snap ring 19 is provided in the anti-disengagement groove 18 to prevent the rigid ball from falling out of the anti-rotation hole 15. The side wall of the adjusting rod 3 is evenly provided with two, three, four, or five anti-rotation grooves 17, one side of the anti-rotation member 16 is disposed in the anti-rotation groove 17, and the other side of the anti-rotation member 16 is provided with the anti-rotation hole 15, thus preventing the adjusting rod 3 from rotating during use. Since the anti-rotation component 16 is a steel ball as in the prior art, an anti-detachment retaining spring 19 is provided to prevent the steel ball from detaching from the anti-rotation hole 15. After the anti-detachment retaining spring 19 is engaged, one side of the steel ball contacts the anti-detachment retaining spring 19, and the other side contacts the anti-rotation groove 17. To prevent the anti-detachment retaining spring 19 from moving, an anti-detachment groove 18 is provided on the guide plate 8, and the anti-detachment groove 18 cooperates with the anti-detachment retaining spring 19.

[0035] In some embodiments, a limiting block 20 is provided at the end of the guide rail 6, and a limiting groove 25 that cooperates with the limiting block 20 is provided on the movable tube 2. In this technology, after the guide rail 6 is installed on the fixed tube 1, the limiting block 20 on the guide rail 6 inserts into the limiting groove 25 on the movable tube 2. The limiting groove 25 is an elongated groove, and under the action of the limiting block 20, the movable tube 2 can only move within a limited range. In a gas nail gun, limiting grooves 25 are provided on both sides of the movable tube 2, and two such limiting blocks 20 are provided on the guide rail 6; in an electric nail gun, a limiting groove 25 is provided in the middle of the movable tube 2, and one such limiting block 20 is provided on the guide rail 6.

[0036] In some embodiments, the stabilizing plate 9 is provided with a clearance hole 21 that cooperates with the adjusting rod 3. Since the end of the adjusting rod 3 protrudes through the transmission slider 4, the clearance hole 21 is provided to allow the end of the adjusting rod 3 to enter in order for the stabilizing plate 9 to contact the transmission slider 4. At the same time, the limiting snap ring 14 can also enter the clearance hole 21.

[0037] In some embodiments, an adjustment disc 22 that cooperates with the adjustment block 11 is coaxially fixedly provided on the end of the adjustment rod 3. The adjustment disc 22 serves two purposes: first, it facilitates manual rotation of the adjustment rod 3; second, it allows for better contact with the adjustment block 11, reducing the design height of the adjustment block 11.

[0038] In some embodiments, a brake ring 23 is provided on the piston rod 5, and the brake ring 23 cooperates with the piston 24 on the piston rod 5. Since the piston rod 5 pushes forward directly during operation, the brake ring 23 is provided for cushioning to prevent the piston 24 from colliding with the fixed tube 1.
