Referring to fig. 1, the nailing gun 100 of a preferred embodiment of the present invention can be a pneumatic nailing gun or an electric nailing gun or other types of nailing guns, and the present application is not limited to the specific type of nailing gun 100, as the case may be. Specifically, the nail gun 100 includes a housing 1, a power source (not shown) disposed in the housing 1, and a striker 11 (not shown) driven by the power source to reciprocate relative to the housing 1, and the nail gun 100 further includes a gun head 2 connected to the housing 1, and a magazine 3 for placing and delivering nails to the gun head 2, wherein when a nail in the magazine 3 reaches the gun head 2, the striker 11 is driven by the power source to reciprocate to impact the nail delivered to the gun head 2 to the outside of the gun head 2, thereby implementing a nailing operation.

The power source comprises a balance valve arranged in the main body part, a cylinder and a piston accommodated in the cylinder and connected with the firing pin 11, and the piston reciprocates in the cylinder and drives the firing pin 11 to reciprocate in the gun head 2 under the drive of external force.

Referring to fig. 2 and 3, the nail gun 100 further includes a locking mechanism 4 connected to the housing 1 via a fastener 45, and the locking mechanism 4 moves to be separated from the striker 11 by an external force or returns to be caught by the striker 11 when the external force is removed. Referring to fig. 5 and 6, a notch 111 is formed on the striker 11, and the locking mechanism 4 is engaged with the notch 111. The notch 111 has a holding surface 113 and an arc surface 112 connected to the holding surface 113, and when the locking mechanism 4 is held by the notch 111, the locking mechanism 4 is held against the holding surface 113. When the lock mechanism 4 is moved by an external force to be separated from the striker 11, the lock mechanism 4 rotates around its own axis and moves along the arcuate surface 112 to be separated from the striker 11.

The locking mechanism 4 includes a locking member 41 connected to the fastening member 45 and engaged with the notch 111 of the striker 11, a supporting member 42 connected to the locking member 41, and a restoring member 43 fitted over the supporting member 42 for restoration, and as described above, the locking member 41 has a first locking portion 411 engaged with the notch 111, and the first locking portion 411 is engaged with the notch 111. In this embodiment, the reset member 43 is a torsion spring, and indeed, in other embodiments, the reset member 43 may be other, which is not specifically limited herein, depending on the actual situation.

The end of the supporting member 42 has a mounting portion 43, the locking member 41 has a mounting hole matching with the mounting portion 43, and the supporting member 42 has a threaded hole formed by recessing the end surface of the supporting member 42 and matching with the fastening member 45, after the mounting portion 43 of the supporting member 42 is butted with the mounting hole of the locking member 41, the fastening member 45 is mounted to fixedly connect the supporting member 42 and the locking member 41. The fastening member 45 is a conventional structure, such as a screw, and will not be described herein. Wherein the hole diameter of the mounting hole is smaller than the end surface of the fastening member 45, so that the fastening member 45 is caught by the surface of the locking member 41 and the supporting member 42 is connected to the locking member 41.

The locking mechanism 4 further comprises a skirt 421, the skirt 421 is integrally formed with the support member 42, and the torsion spring 43 is fixedly connected to the skirt 421. Specifically, the torsion spring 43 includes a torsion spring body 431, a first end portion 432 vertically disposed to the torsion spring body 431, and a second end portion 433 disposed in parallel to the torsion spring body 431, wherein in the height direction of the nail gun 100, the first end portion 432 is disposed downward and connected to the skirt 421, and the second end portion 433 abuts against the housing 1. Indeed, in other embodiments, the angle between the first end portion 432 and the torsion spring body 431 may be other, as long as the corresponding effect is achieved, and is not specifically limited herein, depending on the actual situation. In order to prevent the torsion spring 43 from being separated from the supporting member 42, a through hole 422 is formed in the skirt 421, and the first end portion 432 passes through the through hole 422 to be fixedly connected to the supporting member 42.

By providing the support member 42 directly connected to the locking member 41 and connecting the torsion spring 43 to the skirt 421 of the support member 42, the skirt 421 is not separated from the support member 42 by the cyclic impact force of the torsion spring 43 due to the integral formation of the skirt 421 and the support member 42, so that the failure of the entire locking mechanism 4 is not caused, and the locking mechanism is simple in structure and easy to manufacture and install.

The skirt 421 is provided at the bottom of the support member 42 in the height direction of the nail gun 100. Indeed, in other embodiments, the skirt 421 can be arranged at other positions of the supporting member 42, and is not limited thereto, as long as the corresponding technical effect is achieved. The locking mechanism 4 further comprises a bearing 44 fitted over the support 42 and disposed between the torsion spring 43 and the locking member 41.

Referring to fig. 4, the nail gun 100 further includes a retaining mechanism 5 that is retained to or separated from the lock mechanism 4 so that the lock mechanism 4 is retained to or separated from the striker 11, and the retaining mechanism 5 includes a retaining member 51 that is retained to or separated from the locking member 41. The locking member 41 also has a second locking portion 412, and the retaining member 51 has a bent portion 511 that retains the second locking member 41. Referring to fig. 5, when the catching mechanism 5 catches the locking mechanism 4, the bending portion 511 abuts against the second locking portion 412. Referring to fig. 6, when the retaining mechanism 5 moves in the first direction under the action of external force, so that the bent portion 511 is separated from the second locking portion 412, the locking mechanism 4 moves relative to the housing 1 under the pushing action of the striker 11 and against the elastic force of the torsion spring 43, so that the first locking portion 411 is separated from the notch 111, thereby separating from the striker 11; when the retaining structure moves to a second direction opposite to the first direction under the action of an external force, the bent portion 511 abuts against the second locking portion 412, the striker 11 retracts, the locking member 41 is reset under the action of the torsion spring 43, and the first locking portion 411 and the notch 111 are retained again, so that the striker 11 is locked again.

In summary, the following steps: through being provided with the support piece 42 with locking piece 41 direct connection, support piece 42 has the shirt rim 421 with torsional spring 43 fixed connection, and when the cyclic impact force transmission of torsional spring 43 was given shirt rim 421, because shirt rim 421 and support piece 42 integrated into one piece set up, can not drop under the cyclic impact force of torsional spring 43 to avoid the emergence of whole locking mechanical system 4 inefficacy, improved product quality.
