The patent adopts a semiconductor laser stack composed of at least two semiconductor laser bars, and a fast-axis collimating lens and a light-emitting window are sequentially arranged in the laser light-emitting direction; the light-emitting window is arranged at the geometric connection critical position where the laser beams emitted by different laser bars do not generate energy superposition or at any position thereafter; the utility model solves the problem that due to the volume, energy and technical limitations of the laser, these optical systems are often large in size, complex in structure and high in cost, which limits the application of terminal medical modules.

[0004] The inventors discovered in their daily work that, during the use of the device, there is a problem that the optical fiber is easily broken due to external forces when the device outputs the light source through the optical fiber. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcoming in the prior art that optical fibers are prone to breakage, and to propose a semiconductor laser light source module.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: a semiconductor laser light source module, comprising a main body and a protective device, a cover plate is provided on the upper surface of the main body, an insert plate is provided at one end of the main body, a light output head is provided at one end of the main body, the protective device is provided on the surface of the light output head, the protective device comprises a protective cover and a limiting groove, the limiting groove is provided on the surface of the light output head, the protective cover is provided on the surface of the light output, a connecting column is fixedly connected to the surface of the protective cover, a supporting hole is provided inside the connecting column, a locking ball is slidably connected to the inner wall of the supporting hole, one end of the locking ball is engaged with the inside of the limiting groove, and one end of the locking ball is fixedly connected to a blocking block.

[0007] Furthermore, a first spring is fixedly connected to the surface of the locking ball, an end of the first spring away from the locking ball is fixedly connected to the inner wall of the abutment hole, and the inner wall of the abutment hole is slidably connected to a push rod. By setting the locking ball, the connection between the protective cover and the light output head can be restricted, thereby reducing the situation where the protective cover is easily separated from the light output head when the device is in use.

[0008] Furthermore, a pull ring is slidably connected to the surface of the protective cover, and the pull ring is fixedly connected to one end of the resisting rod. The resisting rod is provided to facilitate the restriction of the resisting block.

[0009] Furthermore, a second spring is fixedly connected to the surface of the pull ring, and one end of the second spring away from the abutment ring is fixedly connected to the surface of the protective cover. The second spring is provided to facilitate application of a reset elastic force to the pull ring.

[0010] Furthermore, an anti-slip device is provided on the surface of the plug board, and the anti-slip device includes a plug and a positioning block, the positioning block is fixedly connected to the surface of the main body, the plug is located inside the plug board and is plugged in, the side of the plug is fixedly connected with a connecting block, the interior of the positioning block is fixedly connected with a sliding rod, and the surface of the sliding rod is sleeved and connected with a pull plate, and by providing the sliding rod, the pull plate can be limited, which reduces the risk of the pull plate shaking easily when the equipment is in use, making it difficult for the anti-slip device to limit the positioning block.

[0011] Furthermore, a third spring is sleeved and connected to the surface of the slide rod, and both ends of the third spring are fixedly connected to the inside of the positioning block and the surface of the pull plate respectively.

[0012] Furthermore, an anti-slip rod is fixedly connected to the upper surface of the pull plate, and the anti-slip rod is engaged with the surface of the connecting block. The anti-slip rod is provided to facilitate the restriction of the positioning block.

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

[0014] In the utility model, when the device is in use, the output is carried out through the optical fiber when the device is started. Before using the device, the user pulls the pull ring, and the movement of the pull ring drives the movement of the resisting rod. When the pull ring moves, it drives the second spring to be displaced and deformed to generate elastic force, and then the resisting rod moves away from the surface of the resisting block, and then the locking ball loses its restraint, and the protective cover is pulled to drive the locking ball to move. When the locking ball moves, it drives the first spring to be displaced and deformed to generate elastic force, and then the protective cover is separated from the surface of the light output head. By setting up the protective device, the optical fiber inside the light output head is effectively protected, which plays a role in protecting the optical fiber, reduces the situation that the optical fiber is easily broken by the external force when the device outputs the light source through the optical fiber when in use, and improves the practicality of the device.

[0015] When the user pulls the pull plate, the pull plate moves, which drives the anti-slip rod to move. The anti-slip rod moves away from the surface of the connecting block. When the pull plate moves, it drives the third spring to be displaced and deformed to generate elastic force, and then the plug loses its restraint. By setting the anti-slip 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 forces and detached from the inside of the plug plate when the device is in use, causing a short circuit in the device and difficulty in normal operation, thereby improving the practicality of the device.

[0027] In this embodiment, by providing the locking ball 55, the connection between the protective cover 51 and the light output head 4 can be restricted, thereby reducing the risk of the protective cover 51 being easily separated from the light output head 4 when the device is in use.

[0028] Specifically, a pull ring 59 is slidably connected to the surface of the protective cover 51 , and the pull ring 59 is fixedly connected to one end of the stop rod 58 . The stop rod 58 is provided to facilitate limiting the stop block 57 .

[0029] Specifically, a second spring 510 is fixedly connected to the surface of the pull ring 59 , and one end of the second spring 510 away from the abutment ring is fixedly connected to the surface of the protective cover 51 . The second spring 510 is provided to facilitate applying a restoring elastic force to the pull ring 59 .

[0030] In this embodiment: an anti-slip device 6 is provided on the surface of the plug board 3, and the anti-slip device 6 includes a plug 61 and a positioning block 63.

[0031] In this embodiment, the sliding rod 66 is provided to limit the pull plate 65 , thereby reducing the risk of the pull plate 65 shaking when the device is in use, which would make it difficult for the anti-slip device to restrict the positioning block 63 .

When the pull plate 65 moves, it drives the third spring 67 to displace and deform to generate elastic force, and then the plug 61 is freed from the restraint. By setting the anti-slip device 6, the plug 61 is effectively restricted, which plays a role in restricting the plug 61, reducing the risk of the plug 61 being easily affected by external forces and detached from the inside of the plug plate 3 when the device is in use, causing the device to short-circuit and difficult to operate normally, thereby improving the practicality of the device.
