[0117] See also Figure 3 In one embodiment, the electric nail gun further comprises:

[0118] The elastic member 9 has one end that abuts against the base 1, and the other end that abuts against the push rod 3. The elastic member 9 is used to provide a driving force for the push rod 3 to move inward relative to the base 1. Figure 4 When the push rod 3 is driven by the linkage mechanism 4 to move inwardly relative to the base 1 to a set position, the angle between the first link 41 and the second link 42 in the linkage mechanism 4 is the smallest. The lateral force generated by the linkage of the first link 41 and the second link 42 on the push rod 3 is greater than the axial force. Since the elastic member 9 can provide the push rod 3 with a driving force to move inwardly relative to the base 1, it plays a role in increasing the axial force of the push rod 3 when it moves inward, and cooperates with the guide groove 14 to make the push rod 3 move inward more smoothly.

[0119] See also Figure 3 In one embodiment, the elastic member 9 is sleeved on the outer peripheral wall of the push rod 3, and the push rod 3 is used to guide the elastic member 9 so that the elastic member 9 can be stretched and retracted more smoothly.

[0120] In one embodiment, the elastic member 9 may be a spring, or an elastic structure such as a spring sheet, an elastic rubber member, or a bellows, as long as it can provide a driving force for the push rod 3 to move inward relative to the base 1 .

[0121] In one embodiment, the base 1 has a guide hole, and the push rod 3 is movably provided with the guide hole to guide the movement of the push rod 3, so that the push rod 3 can move more smoothly and stably.

[0122] See also Figure 2 In one embodiment, the electric nail gun further comprises:

[0123] The anti-wear sleeve 10 is arranged on the base 1. The anti-wear sleeve 10 has a guide hole. By arranging the guide hole on the anti-wear sleeve 10, wear can be reduced, thereby effectively avoiding the problem of reduced accuracy caused by movement and wear of the push rod 3, so that the push rod 3 can move more stably and sustainably.

[0124] In one embodiment, there are two anti-wear sleeves 10 , and the two anti-wear sleeves 10 are arranged at intervals along the moving direction of the push rod 3 .

[0125] In one embodiment, the anti-wear sleeve 10 is a structure made of copper material, so that the anti-wear sleeve 10 has better anti-wear performance, which can greatly increase the service life of the anti-wear sleeve 10 and reduce maintenance costs.

[0126] Of course, in other embodiments, the anti-wear sleeve 10 may also be a structure made of other wear-resistant materials such as stainless steel.
