[0023] The utility model is now further described with reference to the accompanying drawings.

[0024] Embodiment 1

[0025] like Figures 1 to 7As shown, a nail protection device for a nail gun includes a nail gun head 13, a starting sleeve 11, a nail gun tube 12, a protection seat 21, a protection rod 22, a protection spring 25 and a micro switch. The nail gun head 13 is mounted on the gun seat 3. The nail gun head 13 is provided with a nail hole 130, a push groove 131 and a protection installation groove 132. The protection installation groove 132 is located above the tail of the nail gun head 13, and the push groove 131 is connected to the nail hole 130 and the protection installation groove 132 respectively. Two guide shafts 24 are symmetrically arranged in the protection installation groove 132. The protection seat 21 is provided with a sliding hole 212. The sliding hole 212 of the protection seat 21 is slidably inserted on the guide shaft 24. The two guide shafts 24 improve the stability and reliability of the sliding of the protection seat 21. A push rod 211 is provided at one end of the protection seat 21, and a protection rod 22 is provided at the other end. The protection rod 22 is arranged opposite to the micro switch, and the micro switch is installed in the switch groove 31 of the gun seat 3. The protection seat 21 is located in the protection installation groove 132, and the push rod 211 is movably inserted in the push groove 131. The protection spring 25 is movably inserted on the guide shaft 24, and its two ends respectively abut against the side surfaces of the protection seat 21 and the push groove 131. The starting sleeve 11 is connected to the nail tube 12, and both are movably inserted in the nail hole 130. The starting sleeve 11 is also located outside the gun head 13, and the nail tube 12 is located on one side of the push groove 131, and its end abuts against the end surface of the push rod 211. The protection spring 25 pushes the starting sleeve 11 outward through the pushing rod 211, so that the protection rod 22 is away from the micro switch. When it is necessary to shoot a nail, the starting sleeve 11 is pressed against the position where the nail is required, and then the nail gun is pushed forward. The starting sleeve 11 pushes the pushing rod 211 through the nail tube 12. The pushing rod 211 compresses the protection spring 25, and the protection seat 21 drives the protection rod 22 to move toward the direction of the micro switch. When the protection rod 22 hits the micro switch and is turned on, the switch connected to the trigger of the nail gun can be started, and then the nail is shot.

[0026] When the starting sleeve 11 is not against the object to be nailed, the nail gun cannot work normally and cannot shoot nails, thereby improving safety and avoiding accidents.

[0027] In order to reduce friction and improve the smoothness of sliding of the protection seat 21 , a sliding sleeve is further installed on the sliding hole 212 . The sliding sleeve can be a plastic sleeve or a self-lubricating sleeve. The sliding sleeve is slidably inserted on the guide shaft 24 .

[0028] An insulating elastic column 23 is installed at the end of the protection rod 22. The insulating elastic column 23 can be made of rubber. The insulating elastic column 23 is arranged opposite to the micro switch, which can reduce the impact force on the micro switch and achieve insulation at the same time, thereby improving the overall reliability and stability.

[0029] Embodiment 2

[0030] like Figure 8 and Fig. 9As shown, on the basis of the above embodiment, it also includes an anti-air-hitting device, which is arranged on the protective seat 21 and is arranged opposite to the protective seat 21 and the nail pushing seat 41 of the nail magazine 4, and is used to prevent air-hitting when there is no nail in the nail magazine 4, and air-hitting is easy to cause damage to the nail gun. Specifically, the anti-air-hitting device includes an anti-air-hitting rod 26, an anti-air-hitting sleeve 27 and an anti-air-hitting spring 28. An anti-air-hitting hole 134 is provided on the gun head 13, and the anti-air-hitting hole 134 is vertically arranged and located on one side of the protective mounting groove 132. The anti-air-hitting hole 134 is arranged opposite to the nail magazine 4 below. The anti-air-hitting rod 26 is movably inserted into the anti-air-hitting hole 134, and a positioning ring is provided on the anti-air-hitting rod 26. The anti-air-hitting spring 28 is movably inserted on the anti-air-hitting rod 26, and the two ends are respectively against the hole shoulder and the positioning ring of the anti-air-hitting hole 134. The air defense sleeve 27 is installed at the bottom of the air defense hole 134 and is arranged relative to the positioning ring to limit the air defense rod 26 to rise and fall in the air defense hole 134. The air defense rod 26 is arranged relative to the air defense block 213 on the push nail seat 41.

[0031] An anti-air striking plate 411 is disposed on the nail pushing seat 41 and is arranged opposite to the anti-air striking rod 26 ; an anti-air striking block 213 is disposed on the protection seat 21 and is arranged opposite to the anti-air striking rod 26 .

[0032] When the nails in the nail magazine 4 are used up, the anti-aircraft hitting plate 411 on the nail pushing seat 41 will push the anti-aircraft hitting rod 26 to move upward, and the top of the anti-aircraft hitting rod 26 moves to one side of the anti-aircraft hitting block 213 of the protective seat 21, and the anti-aircraft hitting block 213 limits the movement of the protective seat 21 toward the direction of the micro switch through the anti-aircraft hitting rod 26, thereby preventing air strikes.

[0033] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the claims of the present invention.
