[0031] In order to better explain the utility model and facilitate understanding, the utility model is described in detail below with reference to the accompanying drawings and through specific implementation methods. Figure 2 The orientation is used as a reference.

[0032] Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0033] The utility model provides a locking device, which includes a first locking mechanism 6 and a second locking mechanism 7 that are detachably connected, and the first locking mechanism 6 and the second locking mechanism 7 are detachably connected. In addition, a snap button 8 is provided on the first locking mechanism 6, and the snap button 8 is connected to the internal structure of the first locking mechanism, and the first locking mechanism 6 and the second locking mechanism 7 are separated by pressing the snap button 8. In one embodiment, the first locking mechanism 6 is installed on the machine head sheet metal, and the second locking mechanism 7 is installed on the head shell sheet metal 4. Alternatively, the second locking mechanism 7 can also be installed on the machine head sheet metal, and the first locking mechanism 6 can be installed on the head shell sheet metal 4. When the head shell sheet metal 4 is closed, the second locking mechanism 7 is connected and fixed to the first locking mechanism 6, so that the head shell sheet metal 4 and the machine head sheet metal form a whole to protect the internal laser head 1. When it is necessary to open the head shell sheet metal 4, press the button 8 to separate the machine head sheet metal from the head shell sheet metal 4. It has a simple structure and is easy to operate. It effectively prevents the unstable or failed connection between the head shell sheet metal 4 and the machine head sheet metal due to repeated disassembly, thereby avoiding the situation where the laser head is exposed to the outside, causing damage to the laser head or reducing the service life of the laser head.

[0034] Furthermore, if Figure 1 As shown, the first locking mechanism 6 includes a locking assembly and a housing, the locking assembly is arranged in the housing, and the snap button 8 is arranged on the outer surface of the housing. A through hole is opened on the housing, and the second locking mechanism 7 is detachably connected to the locking assembly after passing through the through hole. A hole is opened on the housing, and the snap button is connected to the locking assembly after passing through the hole, and the snap button is pressed to separate the locking assembly from the second locking mechanism 7.

[0035] Specifically, the first locking mechanism 6 includes a hook and a torsion spring. The hook is rotatably arranged in the housing through a rotating shaft. The torsion spring is arranged on the rotating shaft of the hook. The snap button 8 is connected to the hook, and the hook is driven to rotate by pressing the snap button 8. The second locking mechanism 7 is preferably a lock tongue. A lock hole is provided on the second locking mechanism 7. When the hook is in a connected state with the lock hole, the hook is acted on by the elastic force of the torsion spring, and the hook remains connected with the lock hole. The second locking mechanism 7 is stably connected with the first locking mechanism 6. When the hook is driven to rotate by the snap button 8, the hook is separated from the lock hole, and the second locking mechanism 7 can be separated from the first locking mechanism 6. After the snap button 8 is released, the hook is reset under the action of the torsion spring.

[0036] Furthermore, the first locking mechanism 6 also includes an elastic member, which is preferably a spring, and the first end of the elastic member is connected to the shell. When the hook is in a connected state with the lock hole, the second locking mechanism 7 abuts against the elastic member, and the elastic member provides elastic force for the second locking mechanism 7 to ensure that the second locking mechanism 7 and the hook are always under force. When the hook rotates out of the lock hole, the second locking mechanism 7 is ejected under the action of the elastic member. When the first locking mechanism 6 is used to lock the head shell sheet metal 4, the head shell sheet metal 4 is ejected together with the second locking mechanism 7, which facilitates the opening of the head shell sheet metal 4.

When repairing or debugging the laser head 1, it is only necessary to open the head shell sheet metal 4, and the laser head 1 can be repaired or debugged without disassembly, which is convenient to operate. The bottom surface of the head sheet metal is also set as an opening for the emission of laser. The first locking mechanism 6 is arranged on the machine head sheet metal, and the second locking mechanism 7 is arranged on the head shell sheet metal 4. When the first locking mechanism 6 and the second locking mechanism 7 are in a connected state, the head shell sheet metal 4 is completely connected with the machine head sheet metal, and the head shell sheet metal 4 is in a closed state. The head shell sheet metal 4 covers the side opening of the machine head sheet metal, so as to prevent the head shell sheet metal 4 from opening automatically due to impact force when the laser head 1 runs at high speed, thereby improving the stability of the installation of the head shell sheet metal 4, and the structure is simple, easy to install and highly safe. When the button 8 is pressed, the head shell sheet metal 4 is ejected together with the second locking mechanism 7, so as to facilitate the opening of the head shell sheet metal 4.
