Due to their wide wavelength range, simple production, low cost, easy mass production, small size, light weight, long life, rapid variety development and wide application range, there are more than 300 types of semiconductor laser modules. Semiconductor laser modules have been widely used in laser ranging, laser radar, ignition and detonation, detection instruments, etc., forming a broad market.

[0003] The prior art includes a utility model with a publication number of CN218919553U, which discloses a semiconductor laser module.

The installation groove is set with an opening on one side facing the first wire hole, the temperature sensor and the laser module are installed in the installation groove, and a semiconductor cooling plate is installed in the open bottom of the cover shell, and the heat absorption side of the semiconductor cooling plate is in contact with the heat dissipation copper block; the utility model solves the problem that most of the existing solutions adopt the method of installing a heat sink on the semiconductor laser module to dissipate heat through self-heating or forced air cooling, and this method has poor heat dissipation effect when the semiconductor laser module generates a large amount of heat, and may even cause the service life of the semiconductor laser module to be reduced, and cannot meet the long-term stable operation requirements of the semiconductor laser module.

[0004] The inventors have found in their daily work that when using the device, when the plug is inserted into the main body, the plug is easily affected by external forces, which may cause the plug to be detached from the main body, making it difficult to control the main body.

The first spring is provided to facilitate applying a reset elastic force to the clamping rod.

[0010] Furthermore, a protective device is provided on the surface of the pin, and the protective device includes a positioning block and a protective cover. The side of the positioning block body is fixedly connected, and the protective cover is located on the surface of the pin and is sleeved and connected, one end of the protective cover is clamped with the inner wall of the positioning block, and a protrusion is fixedly connected to the side of the protective cover, and the protrusion is clamped with the inner wall of the positioning block.

[0012] Furthermore, a pressure rod is fixedly connected to the side of the positioning rod, and the pressure rod is slidably connected to the inside of the pressure hole. The pressure rod is provided to facilitate the movement of the positioning rod.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] In the utility model, when the device is in use, the user installs the device and the circuit board, then plugs and connects the pins, and then starts the laser head of the device to emit laser. When using the device, the user presses the card rod, and then the card rod moves to drive the sliding rod to move. When the sliding rod moves, it drives the first spring to displace and deform to generate elastic force, and then the card rod is separated from the inside of the card hole, and then the plug loses its restraint. By setting an anti-detachment device, the plug is effectively restricted, which plays a role in restricting the plug, reduces the risk of the plug being easily affected by external force when the device is in use and is inserted inside the main body, which easily causes the plug to be separated from the inside of the main body and makes it difficult to control the main body, thereby improving the practicality of the device.

By arranging the protection device, the pin is effectively protected, which plays a role in protecting the pin, reduces the situation that the pin is easily hit by external force when the equipment is in use, causing the pin to bend and be damaged, and it is difficult to use normally, thereby improving the practicality of the equipment.

The connecting head 61 is plugged into the inside of the main body 2, and the limiting column 62 is fixedly connected to the surface of the main body 2. The limiting column 62 is clamped with the inner wall of the plug, and a clamping hole 63 is opened on the surface of the limiting column 62. The surface of the plug is slidably connected with a clamping rod 64, and the clamping rod 64 is clamped with the inside of the clamping hole 63.

[0025] Specifically, a sliding rod 66 is fixedly connected to the surface of the clamping rod 64 , and a connecting block 65 is fixedly connected to the surface of the plug.

[0026] In this embodiment: by setting the sliding rod 66, the clamping rod 64 can be limited, which reduces the possibility that the clamping rod 64 is easily shaken when the device is in use, causing the clamping rod 64 to separate from the plug surface and making it difficult to limit the limiting column 62.

[0027] Specifically, the slide bar 66 is slidably connected to the inner wall of the connecting block 65 , and one end of the slide bar 66 away from the clamping rod 64 is fixedly connected to a stop block 67 . The stop block 67 is provided to facilitate limiting the clamping rod 64 .

[0028] Specifically, a first spring 68 is sleeved and connected to the surface of the slide rod 66 , and two ends of the first spring 68 are fixedly connected to the surface of the connecting block 65 and the surface of the clamping rod 64 , respectively. The first spring 68 is provided to facilitate applying a restoring elastic force to the clamping rod 64 .

[0029] In this embodiment: a protective device 7 is provided on the surface of the pin 5, and the protective device 7 includes a positioning block 71 and a protective cover 72. The positioning block 71 is fixedly connected to the side of the main body 2, and the protective cover 72 is located on the surface of the pin 5 and is sleeved and connected. One end of the protective cover 72 is clamped with the inner wall of the positioning block 71, and a protrusion 73 is fixedly connected to the side of the protective cover 72. The protrusion 73 is clamped with the inner wall of the positioning block 71. A positioning hole 74 is opened on the surface of the positioning block 71, and a pressing hole 75 is opened on the protrusion 73. The inner wall of the pressing hole 75 is slidably connected with a positioning rod 76, and one end of the positioning rod 76 is clamped with the inner wall of the pressing hole 75.

[0030] In this embodiment, by providing a protective cover 72, the pin 5 can be protected, thereby reducing the possibility that the pin 5 is easily affected by external forces when the device is in use, causing the pin 5 to be damaged and bent.

When using the device, the user presses the card rod 64, and then the card rod 64 moves to drive the slide bar 66 to move. When the slide bar 66 moves, it drives the first spring 68 to displace and deform to generate elastic force, and then the card rod 64 is separated from the inside of the card hole 63, and then the plug loses its restraint. By setting the anti-detachment device 6, the plug is effectively restricted, which plays a role in restricting the plug, reducing the risk of the plug being easily affected by external force when the device is in use and the plug is inserted into the inside of the main body 2, which may easily cause the plug to be separated from the inside of the main body 2 and make it difficult to control the main body 2, thereby improving the practicability of the device.

[0034] Before using the device, the user presses the pressure rod 78, and the pressure rod 78 moves, which drives the positioning rod 76 to move. When the positioning rod 76 moves, it drives the second spring 77 to displace and deform to generate elastic force, and then the positioning rod 76 is separated from the inside of the positioning hole 74, and then the protrusion 73 loses its restraint, pulling the protective cover 72 away from the surface of the pin 5. By setting up the protective device 7, the pin 5 is effectively protected, which plays a role in protecting the pin 5, reduces the risk of the pin 5 being easily hit by external force when the device is in use, causing the pin 5 to bend and be damaged, and making it difficult to use normally, thereby improving the practicability of the device.
