[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0017] like Figure 1-2 As shown, a safety structure of a lithium-ion nail gun includes a trajectory 11, a guide groove 5 is opened at the upper end of the trajectory 11, a boss 12 is provided on the inner side of the guide groove 5, a threaded hole 4 is provided on the upper end of the boss 12, a ratchet lock 6 is movably connected to the outer side of the boss 12, the ratchet lock 6 is located on the inner side of the guide groove 5, a spring 7 is fixedly connected to the inner wall of the inner side of the ratchet lock 6, a bolt 8 is threadedly connected to the inner side of the threaded hole 4, a wheel disc 3 is installed at the rear end of the trajectory 11, a ratchet body 2 is installed on the upper end of the wheel disc 3, a transmission shaft 1 is installed at the center of the wheel disc 3 and the ratchet body 2, and ratchet teeth 9 are provided on the outer side of the ratchet body 2.

[0018] In this embodiment, the ratchet lock 6 is slidingly connected to the guide groove 5, one end of the ratchet lock 6 is in contact with the front end of the ratchet tooth 9, one end of the spring 7 is fixedly connected to one end of the boss 12, the bolt 8 is in contact with the ratchet lock 6, and there are several groups of ratchet teeth 9, which are distributed on the outside of the ratchet body 2.

[0019] Specifically, the ratchet body 2 and the wheel disc 3 are installed on the transmission shaft 1. When the transmission shaft 1 rotates counterclockwise, the wheel disc 3 and the ratchet body 2 will be driven to rotate synchronously with the center of the transmission shaft 1 as the base point. The ratchet lock 6 will compress the spring 7 when the ratchet body 2 rotates and move along the guide groove 5. When the outermost point of the ratchet teeth 9 rotates past, the ratchet lock 6 will move in the opposite direction along the guide groove 5 under the elastic force of the spring 7 until the ratchet lock 6 grabs the ratchet teeth 9, thus forming a reciprocating motion structural mode. When the ratchet teeth 9 are engaged with the ratchet lock 6, the ratchet teeth 9 and the ratchet lock 6 form an angle of ninety degrees at the engaging position, so that the ratchet body 2 cannot push the ratchet when it rotates clockwise. The lock 6 moves, and the ratchet lock 6 cannot give way. Therefore, when the ratchet body 2 wants to rotate clockwise, it will be locked by the ratchet lock 6 and cannot rotate clockwise. When the ratchet body 2 rotates counterclockwise, the highest point of another group of ratchet teeth 9 will press against the ratchet lock 6 to compress the spring 7, so that the ratchet lock 6 moves inside the guide groove 5 until the highest point of the ratchet teeth 9 passes, and the counterclockwise rotation of the unidirectional movement is realized. The ratchet lock 6 is pushed by the spring 7 to move, so that the ratchet lock 6 presses against the ratchet teeth 9, and the ratchet lock 6 and the ratchet teeth 9 are in contact with each other at 90 degrees, so that the purpose of the ratchet lock 6 controlling the unidirectional rotation direction of the ratchet body 2 is achieved, and then the unidirectional rotation of the wheel disc 3 is also achieved. Thereby ensuring the safety of the product during use and maintenance.

[0020] In this embodiment, a striker 10 is installed on the inner side of the trajectory 11 , and the wheel disc 3 and the striker 10 are meshed with each other.

[0021] Specifically, the ratchet lock 6 and the spring 7 are placed inside the guide groove 5, and are installed in the guide groove 5 by the cooperation of the bolt 8 and the threaded hole 4, and the firing pin 10 is installed inside the trajectory 11, thereby completing the installation.

[0022] Working principle:

[0023] When in use, the ratchet lock 6 and the spring 7 are placed inside the guide groove 5 and are installed in the guide groove 5 by the cooperation of the bolt 8 and the threaded hole 4. Under the elastic action of the spring 7, the ratchet lock 6 slides inside the guide groove 5 under the elastic force of the spring 7, so that the ratchet lock 6 moves toward the ratchet body 2 through the guide groove 5 until the ratchet lock 6 abuts against the ratchet teeth 9 (such as the outer side of the ratchet body 2) outside the ratchet body 2. Figure 1), the ratchet body 2 and the wheel disc 3 are installed on the transmission shaft 1. When the transmission shaft 1 rotates counterclockwise, the wheel disc 3 and the ratchet body 2 will be driven to rotate synchronously with the center of the transmission shaft 1 as the base point. The ratchet lock 6 will compress the spring 7 when the ratchet body 2 rotates and move along the guide groove 5. When the highest point of the ratchet tooth 9 rotates past, the ratchet lock 6 will move in the opposite direction along the guide groove 5 under the elastic force of the spring 7 until the ratchet lock 6 abuts against the ratchet tooth 9, thus forming a reciprocating motion structural mode. When the ratchet tooth 9 is engaged with the ratchet lock 6, the ratchet tooth 9 and the ratchet lock 6 are engaged at an angle of ninety degrees, so that the ratchet body 2 cannot push the ratchet lock 6 to move when it rotates clockwise. , it is impossible to make the ratchet lock 6 give way, so when the ratchet main body 2 wants to rotate clockwise, it will be locked by the ratchet lock 6 and cannot rotate clockwise. When the ratchet main body 2 rotates counterclockwise, the highest point of the other group of ratchet teeth 9 will press against the ratchet lock 6 to compress the spring 7, so that the ratchet lock 6 moves on the inner side of the guide groove 5, and the counterclockwise rotation of the unidirectional movement is realized. The ratchet lock 6 is pushed to move by the spring 7, so that the ratchet lock 6 presses against the ratchet teeth 9, and the ratchet lock 6 and the ratchet teeth 9 are fitted at 90 degrees, so as to achieve the purpose of the ratchet lock 6 controlling the unidirectional rotation direction of the ratchet main body 2, and then the unidirectional rotation of the wheel disc 3 is also realized, thereby ensuring the safety of the product during use and maintenance.
