[0063] This utility model proposes a laser device 100.

[0064] Please refer to Figure 1 , Figures 3 to 7 In some embodiments of this application, the laser device 100 includes a device body 10 and a laser 20. The device body 10 is provided with a mounting bracket 11, in which an air inlet channel is formed. The mounting surface of the mounting bracket 11 is provided with an air passage interface 111 that communicates with the air inlet channel. The laser 20 includes a housing 21, a laser module 22, and an air blowing module 23. The housing 21 is provided on the mounting surface, and a receiving cavity is formed inside the housing 21. The bottom of the receiving cavity is open. At least a portion of the laser module 22 is provided in the receiving cavity, and the light output port 223 of the laser module 22 faces downward toward the housing 21. The housing 21 is provided with an air inlet interface 211, which is opposite to and communicates with the air passage interface 111. The air blowing module 23 communicates with the air inlet interface 211 to guide the airflow toward the front of the light output port 223.

[0065] The laser device 100 proposed in this application can be a laser engraving machine, laser marking machine, laser cutting machine, etc. The laser device 100 includes a main body 10 and a laser 20. The main body 10 of the laser device 100 is provided with a mounting bracket 11 for mounting the laser 20. One side plate of the mounting bracket 11 is the mounting surface, and the laser 20 is mounted on the mounting surface. In the laser device 100, the processing platform for placing processing materials is located below the laser 20, so that the light outlet 223 of the laser 20 is set downward. In this case, the mounting surface of the mounting bracket 11 can be a vertical plane, so that the side wall of the laser 20 is fixed to the mounting surface; or the mounting surface of the mounting bracket 11 can be set horizontally downward, so that the top wall of the laser 20 is fixed to the mounting surface. The connection between the laser 20 and the mounting bracket 11 can be achieved by setting a dovetail groove on the mounting bracket 11 and setting a corresponding plug-in structure on the housing 21, so that the housing 21 and the mounting bracket 11 can be plugged in and matched. Alternatively, the connection between the laser 20 and the mounting bracket 11 can also be at least one of the following: snap-fit ​​connection, bolt connection, magnetic connection, etc., which is not limited here.

[0066] The laser 20 includes a housing 21, a laser module 22, and an air-blowing module 23. The housing 21 serves as a support and mounting base, and a cavity is formed within the housing 21. An opening communicating with the cavity is provided at the bottom of the housing 21. At least a portion of the laser module 22 is disposed within the cavity, and the light-emitting port 223 of the laser module 22 faces the bottom opening of the housing 21 to emit laser light downwards. The air-blowing module 23 can be fixed to the housing 21, fixed to the laser module 22, or fixed to other structures of the laser 20, such as a heat dissipation module. The air blowing module 23 can be equipped with an air blowing head facing the front of the light output port 223 of the laser module 22, or it can be equipped with a guide cavity 2321 covering the light output port 223 as in the following embodiments, or an airflow inlet can be opened on the side wall of the light output channel 221 of the laser module 22, and the air blowing module 23 can be connected to the airflow inlet. All of these methods can guide the airflow to blow towards the front of the light output port 223 for dust removal, which can blow away the dust and smoke in front of the light output port 223 and prevent dust and other impurities from adhering to the optical lenses 222 such as the window mirror or focusing mirror, thereby avoiding affecting the laser emission. At the same time, the airflow can blow towards the processing position to prevent the processing position from being contaminated with dust, which plays a good role in dust removal and dust prevention and ensures the processing effect.

[0067] Furthermore, in this embodiment, an air intake channel is provided in the mounting bracket 11 of the device body 10, and an air passage interface 111 communicating with the air intake channel is provided on the mounting surface of the mounting bracket 11. The air intake channel can extend through both sides of the mounting bracket 11, or the other end of the air intake channel, away from the air passage interface 111, can be opened on either side between the two sides. The other end of the air intake channel, away from the air passage interface 111, can be used to connect to an air supply structure 30 such as an air pump. When the laser 20 is mounted on the mounting surface of the mounting bracket 11, the air intake interface 211 on the side wall of the laser 20 housing 21 is opposite to and communicates with the air passage interface 111 on the mounting surface, thereby allowing the laser 20 to communicate with the air supply structure 30 such as an air pump through the air intake channel. This configuration allows the installation of the laser 20 and the connection of the gas supply to the laser 20 to be performed simultaneously. The gas supply is connected at the same time as the laser 20 is installed, eliminating the need to connect the gas supply before or after the installation of the laser 20, thus improving the ease of installation and removal of the laser 20.

[0068] During laser processing, the air supply structure 30, such as the air pump, drives the airflow from the air inlet channel and air inlet 211 into the blowing module 23, and then blows it towards the front of the laser output head 232 of the laser module 22 for dust removal.

[0069] Therefore, it is understood that the laser device 100 of this application includes a device body 10 and a laser 20 installed on the device body 10. The laser 20 is provided with an air blowing module 23, which can be connected to the air supply structure 30 to guide the airflow to the front of the light outlet 223 of the laser 20. This can prevent dust and other debris from adhering to the optical lens 222 of the laser module 22 during the processing. It can also blow away the dust at the processing position in front of the light outlet 223, thereby reducing the impact of dust on the laser processing process and ensuring the laser processing effect.

[0070] Furthermore, within the main body 10 of the laser device 100, an air intake channel is formed within the mounting bracket 11 for mounting the laser 20. This air intake channel can communicate with the air supply structure 30. An air passage interface 111 communicating with the air intake channel is provided on the mounting surface of the mounting bracket 11. Simultaneously, an air intake interface 211 communicating with the air blowing module 23 is provided on the outer shell 21 of the laser 20. When the laser 20 is mounted on the mounting surface of the mounting bracket 11, the air intake interface 211 and the air passage interface 111 are positioned opposite each other and communicate with each other. With this configuration, the airflow driven by the air supply structure 30 can pass through the air intake channel, the air passage interface 111, the air intake interface 211, and the air blowing module 23 to be blown towards the front of the light outlet 223 of the laser module 22. In other words, this application allows the installation of the laser 20 and the connection of the laser 20 to the gas supply to be performed simultaneously. The gas supply is already connected when the laser 20 is installed, eliminating the need to connect the gas supply before or after the installation of the laser 20, thus improving the ease of installation and removal of the laser 20.

[0071] Please refer to Figure 5 In some embodiments of this application, a sealing ring 112 is sandwiched between the outer shell 21 and the mounting bracket 11, and the sealing ring 112 is arranged around the circumference of the air passage interface.

[0072] In this embodiment, a sealing ring 112 is provided between the laser 20 and the mounting bracket 11, and the sealing ring 112 is arranged circumferentially around the gas passage interface 111. The sealing ring 112 can be made of elastic materials such as rubber, silicone, or silicone rubber. When the laser 20 and the mounting bracket 11 clamp the sealing ring 112, the sealing ring 112 can undergo elastic deformation and fit tightly against the mounting bracket 11 and the laser 20 respectively, so that the sealing ring 112 and the laser 20 and the mounting bracket 11 form a sealed cavity, improving the sealing performance between the air inlet interface 211 and the gas passage interface 111 and avoiding air leakage.

[0073] The sealing ring 112 can be fixed to the mounting bracket 11 or to the outer shell 21 of the laser 20, and there is no limitation on this.

[0074] Please refer to Figure 5In some embodiments of this application, the mounting surface is recessed with a fixing groove 114, the air inlet 211 is opened on the bottom wall of the fixing groove 114, and the sealing ring 112 is provided in the fixing groove 114 and protrudes from the mounting surface.

[0075] In this embodiment, the sealing ring 112 is fixed to the mounting bracket 11 of the main body 10 of the device. Therefore, when other lasers 20 need to be replaced, it is not necessary to install the sealing ring 112 on each laser 20, reducing the usage of the sealing ring 112. The mounting surface of the mounting bracket 11 has a recessed fixing groove 114, allowing the air passage interface 111 to be located on the bottom wall of the fixing groove 114. The sealing ring 112 is installed in the fixing groove 114, surrounding the air passage interface 111. The fixing groove 114 limits the sealing ring 112, preventing it from being misaligned and unable to surround the outer periphery of the air passage interface 111 and the air inlet interface 211. Furthermore, a portion of the sealing ring 112 protrudes from the fixing groove 114, ensuring that the laser 20 can abut against the sealing ring 112 when mounted on the mounting surface, thus achieving better sealing performance.

[0076] Please refer to Figure 5 In some embodiments of this application, the device body 10 further includes a locking member 113, which fixes the sealing ring 112 to the mounting bracket 11.

[0077] In this embodiment, a locking member 113 is provided on the main body 10 of the device. The locking member 113 acts between the mounting bracket 11 and the sealing ring 112 to fix the sealing ring 112 onto the mounting bracket 11. The locking member 113 can be an adhesive structure, such as glue, double-sided tape, or Velcro; it can also be a screw or a detachable structure configured to press the outer or inner ring of the sealing ring 112. Using the locking member 113 to fix the sealing ring 112 can improve the connection strength between the sealing ring 112 and the mounting bracket 11, and reduce the risk of the sealing ring 112 falling off or shifting.

[0078] Please refer to Figure 5 In some embodiments of this application, the locking member 113 is provided with an air outlet 1133 through both ends. The locking member 113 passes through the sealing ring 112 and is connected to the mounting bracket 11. The air outlet 1133 is connected to the air passage interface 111.

[0079] In this embodiment, the locking member 113 can be hidden inside the sealing ring 112, thereby preventing the laser 20 from being scratched by the locking member 113 or from failing to adhere tightly to the sealing ring 112 when the laser 20 is fixed to the mounting bracket 11. Simultaneously, the locking member 113 needs to have through-holes 1133 at both ends to prevent blockage of the air passage interface 111. The connection between the locking member 113 and the air passage interface 111 can be an interference fit, adhesive bonding, or threaded connection, etc., and is not limited here.

[0080] Please refer to Figure 5 In some embodiments of this application, the locking member 113 includes a locking part 1131 and a pressing part 1132 connected together. The pressing part 1132 is located at one end of the locking part 1131. The cross-sectional dimension of the pressing part 1132 is larger than that of the locking part 1131. The air outlet 1133 passes through the locking part 1131 and the pressing part 1132. The locking part 1131 passes through the sealing ring 112 and is inserted into the air passage interface 111 and fixedly connected to the mounting bracket 11. The pressing part 1132 presses the sealing ring 112 so that the sealing ring 112 is fixed to the mounting bracket 11.

[0081] In this embodiment, the locking member 113 presses the sealing ring 112 onto the mounting bracket 11. Specifically, the locking member 113 includes a locking part 1131 and a pressing part 1132 connected together. The air outlet 1133 passes through the locking part 1131 and the pressing part 1132. The locking part 1131 passes through the sealing ring 112 and is inserted into the air passage interface 111, and is connected and fixed to the mounting bracket 11. The pressing part 1132 is located on the outside of the air passage interface 111. The sealing ring 112... The inner ring is provided with an abutment portion 1121. The abutment portion 1121 can be arranged around the inner ring of the sealing ring 112, or it can be arranged at a part of the inner ring. For example, at least two abutment portions 1121 are arranged at intervals along the inner ring. When the locking portion 1131 of the locking member 113 is inserted into the air passage interface 111, the pressing portion 1132 of the locking member 113 is pressed against the abutment portion 1121 of the sealing ring 112, thereby pressing and fixing the sealing ring 112 onto the mounting bracket 11.

[0082] Please refer to Figure 4 In some embodiments of this application, the air inlet 117 of the air intake channel 116 is located on the top surface of the mounting bracket 11.

[0083] In this embodiment, the air inlet 117 of the air intake channel for connecting the air supply structure 30 is opened on the top surface of the mounting bracket 11. With this arrangement, the air intake pipe 12 connecting the air supply structure 30 and the air intake channel can be connected to the top of the mounting bracket 11, which is away from the processing position and the laser, and facilitates the connection of the air intake pipe 12.

[0084] Please refer to Figure 4 In some embodiments of this application, the main body 10 of the device also includes an air inlet connector 17, which is installed at the air inlet 117 of the air inlet channel 116 and communicates with the air inlet channel 116. The air inlet connector 17 is used to connect the air inlet pipe 12.

[0085] In this embodiment, the air intake connector 17 and the air intake port 117 can be connected by a plug-in joint or by a threaded connection; for example, a threaded connector can be used as the air intake connector 17. By providing the air intake connector 17, it is convenient to connect the air intake pipe 12 and the air intake channel 116.

[0086] Please refer to Figure 7 In some embodiments of this application, the laser module 22 is vertically adjustable relative to the outer shell 21, and the air blowing module 23 is disposed on the laser module 22; the laser 20 also includes an air guide hose 233, which connects the air inlet 211 and the air blowing module 23, and the air guide hose 233 adaptably deforms as the laser module 22 is raised or lowered.

[0087] In this embodiment, the laser module 22 in the laser 20 can be raised and lowered within the housing 21 by the lifting module to adjust the height of the laser focus. In the laser device 100, the laser 20 is fixed at the same height by the housing 21. Only the lifting module within the laser 20 drives the laser module 22, or a portion of the structure including the laser module 22, to rise and fall to adjust the height of the laser focus. This eliminates the need to raise and lower the entire laser 20 within the laser device 100, making the process of adjusting the laser focus height much easier.

[0088] In this embodiment, the air blowing module 23 is fixed to the laser module 22, and a flexible air guide hose 233 is provided in the accommodating cavity. The flexible air guide hose 233 can be bent and deformed as needed. The flexible air guide hose 233 can be made of materials such as plastic, rubber, PVC (polyvinyl chloride), PE (polyethylene), and PP (polypropylene). One end of the flexible air guide hose 233 is connected to the air inlet 211, and the other end of the flexible air guide hose 233 is connected to the air blowing module 23. The length of the flexible air guide hose 233 is greater than the straight-line distance between the air blowing module 23 and the air inlet 211, and the flexible air guide hose 233 is partially bent. With this configuration, the air blowing module 23 can rise and fall together with the laser module 22, and the flexible air guide hose 233 can adapt to move with the air blowing module 23, maintaining the connection with the air blowing module 23. This ensures that the air blowing module 23 can always form a relatively stable airflow at the front end of the laser head 232 of the laser module 22, ensuring a good dust removal effect.

[0089] Please refer to Figures 8 to 10In some embodiments of this application, the air blowing module 23 is covered outside the light outlet 223, and the air blowing module 23 is provided with a flow guiding cavity 2321 and an outlet 2322 communicating with the flow guiding cavity 2321.

[0090] In this embodiment, the air blowing module 23 is covered outside the light emission port 223 of the laser module 22 and forms a flow guiding cavity 2321. The light emission port 223 is located in the flow guiding cavity 2321, and the air blowing module 23 has an outlet 2322 that communicates with the flow guiding cavity 2321. The outlet 2322 of the flow guiding cavity 2321 is arranged opposite to the light emission port 223 of the laser module 22, so that the laser can be emitted through the outlet 2322. During laser processing, the gas supply structure 30 supplies airflow to the blowing module 23 through the air inlet channel. The airflow is blown outward through the guide cavity 2321 and the outlet 2322. This configuration can form an airflow around the light outlet 223 in the guide cavity 2321, which can prevent dust and other impurities from entering the guide cavity 2321 and entering the light outlet 223 of the laser module 22 or adhering to the optical lens 222 such as the window mirror or focusing mirror. When the airflow is blown out from the outlet 2322, it can also blow away the dust and smoke outside the outlet 2322, thereby avoiding affecting the laser emission.

[0091] It should be noted that in this embodiment, the air blowing module 23 can be configured to simply cover the light outlet 223 and form a flow guide cavity 2321, or it can be configured as a combination of the air guide structure 231 and the light outlet head 232 in the following embodiment.

[0092] Please refer to Figure 9 and Figure 10 In some embodiments of this application, the air blowing module 23 includes an air guiding structure 231 and an output head 232. The air guiding structure 231 is located below the laser module 22. The air guiding structure 231 has an air guiding channel 2313 that communicates with the air inlet interface 211. The air guiding channel 2313 communicates with the air inlet interface 211. The end of the air guiding structure 231 near the output port 223 has a clearance hole 2314. The wall of the clearance hole 2314 is provided with an air guiding port that communicates with the air guiding channel 2313. The output head 232 is covered by the clearance hole and forms a flow guiding cavity 2321 with the clearance hole. The output head 232 has an outlet 2322.

[0093] In this embodiment, the air blowing module 23 includes an air guiding structure 231 and a light emitting head 232. Both the light emitting head 232 and the air guiding structure 231 are covered below the laser module 22. The air guiding structure 231 includes a connected air guiding part 2311 and a connecting part 2312. An air guiding channel 2313 is formed in the air guiding part 2311. The connecting part 2312 is covered at the light emitting port 223 and has a clearance hole for avoiding the light emitting port 223 of the laser module 22. The air guiding channel 2313 and the clearance hole are interconnected through an air guiding port on the wall of the clearance hole. The light emitting head 232 is covered on the clearance hole and is connected to the connecting part 2312 of the air guiding structure 231. The light emitting head 232 and the air guiding structure 231 can be integrally set to improve the overall structural stability of the air blowing module 23. Alternatively, the light emitting head 232 and the air guiding structure 231 can be detachably connected. With this configuration, the gas source can be connected to the inlet of the gas guide structure 231 that is far from the light outlet 223. This avoids the gas inlet pipe 12, which connects to the gas source, from extending directly to the light outlet 223 of the adjacent laser module 22, thereby preventing the gas inlet pipe 12 from blocking the light outlet 223 or causing other effects on the laser processing.

[0094] Please refer to Figure 8 and Figure 9 In some embodiments of this application, an air pipe connector 234 is inserted at one end of the air guide channel 2313 away from the flow guide cavity 2321. The end of the air pipe connector 234 connected to the air guide hose 233 extends upward along the lifting direction of the laser module 22. This arrangement ensures that a portion of the air guide hose 233 connected to the blowing module 23 extends along the lifting direction of the laser module 22, reducing interference of the air guide hose 233 with the lifting process of the laser module 22 and the blowing module 23, and avoiding excessive bending angle of the air guide hose 233, thus making the airflow supplied to the blowing module 23 more stable.

[0095] Please refer to Figure 11 and Figure 12 In some embodiments of this application, the laser module 22 is provided with a light emission channel 221, an optical lens 222 is provided in the light emission channel 221, a light emission port 223 is located at one end of the light emission channel 221, and an airflow inlet is provided on the side wall between the light emission port 223 and the optical lens 222, and the air blowing module 23 is connected to the airflow inlet.

[0096] In this embodiment, the laser module 22 is provided with a light emission channel 221, and an optical lens 222 is provided in the light emission channel 221. The optical lens 222 can be a focusing lens, used to reduce the size of the laser spot, increase the energy density of the laser spot, and improve processing accuracy and efficiency. In addition, the optical lens 222 can also include a window lens provided on the side of the focusing lens facing the light emission port 223. The window lens can be used to protect the focusing lens and other structures, preventing dust and other debris from entering the laser module 22 along the light emission channel 221. In this embodiment, the light emission port 223 of the light emission channel 221 is spaced apart from the optical lens 222, and an airflow inlet is opened on the side wall of the light emission channel 221 between the optical lens 222 and the light emission port 223. At this time, the air blowing module 23 is an air pipe connector 234, which is connected to the airflow inlet to connect the airflow inlet and the air intake interface 211. With this configuration, when the gas supply structure 30 supplies gas to the laser 20 through the air inlet channel, the airflow can enter the light output channel 221 through the air blowing module 23. However, due to the setting of the optical lens 222, the airflow can only flow out from the light output port 223, thereby blowing away dust and other debris in front of the light output port 223 and blowing away dust at the processing position, thus improving the laser processing effect.

[0097] Please refer to Figures 1 to 3 In some embodiments of this application, the main body 10 of the device includes a translation component 13, which includes an intersecting first slide rail 131 and a second slide rail 132. The second slide rail 132 is slidably disposed on the first slide rail 131, and the mounting bracket 11 is slidably disposed on the second slide rail 132.

[0098] In this embodiment, a translation component 13 is provided in the main body 10 of the device, defining a first direction and a second direction that are perpendicular to each other. The translation component 13 includes an intersecting first slide rail 131 and a second slide rail 132. The first slide rail 131 extends along the first direction, and the second slide rail 132 extends along the second direction. The second slide rail 132 is slidably disposed on the first slide rail 131 so that the second slide rail 132 can slide along the length direction of the first slide rail 131. The mounting bracket 11 is slidably disposed on the second slide rail 132 so that the mounting bracket 132 drives the laser 20 to slide along the length direction of the second slide rail 132. The translation component 13 also includes a first driving member for driving the second slide rail 132 to slide along the first slide rail 131, and a second driving member for driving the mounting bracket 11 to slide along the second slide rail 132. The arrangement of the translation component 13 allows the laser 20 to be moved to different positions for processing.

[0099] Please refer to Figures 1 to 3In one embodiment of this application, the main body 10 of the device further includes a first cable chain 14 and a second cable chain 15. The first cable chain 14 is disposed on the first slide rail 131, one end of the first cable chain 14 is connected to the first slide rail 131, and the other end of the first cable chain 14 is connected to the second slide rail 132. The second cable chain 15 is disposed on the second slide rail 132, one end of the second cable chain 15 is connected to the second slide rail 132, and the other end of the second cable chain 15 is connected to the mounting bracket 11. The laser device 100 also includes an air inlet pipe 12, which passes through the first cable chain 14 and the second cable chain 15. One end of the air inlet pipe 12 is connected to the air inlet 117 of the air inlet channel 116, and the other end of the air inlet pipe 12 is used to connect to the air supply structure 30.

[0100] In this embodiment, a first drag chain 14 and a second drag chain 15 are provided in the main body 10 of the device. The air inlet pipe 12, which connects the air supply structure 30 and the air inlet channel, is passed through the first drag chain 14 and the second drag chain 15. This can limit and protect the air inlet pipe 12, prevent the air inlet pipe 12 from becoming scattered and affecting the movement of the laser 20, and prevent the air inlet pipe 12 from being damaged.

[0101] Combined with reference Figure 4 , Figure 6 as well as Figure 7 In one embodiment of this application, the mounting bracket 11 is provided with a first connecting part 115, and the outer shell 21 is provided with a second connecting part 212. The first connecting part 115 and the second connecting part 212 are engaged by a snap-fit ​​structure or by a slot structure.

[0102] It is understandable that there are various ways in which the first connecting part 115 and the second connecting part 212 can be connected, such as, but not limited to: when one of the first connecting part 115 and the second connecting part 212 is a hook and the other is a hole, the hook and the hole engage; when one of the first connecting part 115 and the second connecting part 212 is a connector and the other is a slot 1151, the connector and the slot 1151 engage. By setting the first connecting part 115 and the second connecting part 212, the laser 20 can be detachably connected to the mounting bracket 11.

[0103] Combined with reference Figure 4 , Figure 6 as well as Figure 7 In one embodiment of this application, the first connecting part 115 is configured as a slot 1151, and the second connecting part 212 is configured as a plug, which is inserted into the slot 1151. By using the plug and slot 1151 to engage, the laser 20 can be easily assembled and disassembled, thereby improving the ease of assembly and disassembly of the laser device 100.

[0104] Please refer to Figure 6In one embodiment of this application, the laser device 100 further includes a locking and releasing structure 16 movably disposed on the mounting bracket 11. The locking and releasing structure 16 has a locked state and an unlocked state. In the locked state, the locking and releasing structure 16 confines the plug in the slot 1151. In the unlocked state, the locking and releasing structure 16 is separated from the plug, and the plug can be removed from the slot 1151.

[0105] It is understood that the locking and unlocking structure 16 can switch between the locked and unlocked states by rotation, by movement, or by a combination of rotation and movement. The specifics are not limited here.

[0106] When the connector is inserted into the slot 1151, there is a gap between the connector and the wall of the slot 1151, which affects the stability of the laser 20 mounted on the mounting bracket 11. To avoid this, in the locked state, the locking and releasing structure 16 of this solution is inserted into the slot 1151 and abuts against the connector. The abutting direction of the locking and releasing structure 16 and the connector is set at an angle to the direction in which the connector is inserted into the slot 1151, so as to confine the connector within the slot 1151. At this time, the connector cannot move within the slot 1151, thereby ensuring that the connector is stably installed in the slot 1151, that is, the second connecting part 212 on the laser 20 can be stably installed on the first connecting part 115. When it is necessary to remove the laser 20 from the mounting bracket 11, the locking and releasing structure 16 is released from the second connecting part 212 in the unlocked state to release the confinement of the connector, and the connector can be removed from the slot 1151, that is, the laser 20 can be replaced at this time.

[0107] Please refer to Figure 6 In one embodiment of this application, the locking and unlocking structure 16 includes a toggle member 161 and a locking accessory 162. The toggle member 161 is rotatably disposed on the mounting bracket 11 and has a locked position and an unlocked position. The locking accessory 162 can enter and exit the slot 1151. During the process of the toggle member 161 rotating from the unlocked position to the locked position, it can drive the locking accessory 162 into the slot 1151 to abut against the connector, so that the connector is confined within the slot 1151.

[0108] Understandably, the mounting bracket 11 has a slot 1151, and the laser 20 has a connector. By aligning the connector with the slot 1151 and inserting it, the laser 20 can be mounted on the mounting bracket 11. The locking and releasing structure 16 includes a toggle member 161 and a locking accessory 162. The toggle member 161 is rotatably mounted on the mounting bracket 11, and the locking accessory 162 is movably mounted on the mounting bracket 11. By driving the toggle member 161 to rotate, the locking accessory 162 can be moved. When the locking accessory 162 moves towards the side closer to the connector, it can abut against the connector. At this time, the locking accessory 162 can confine the connector within the slot 1151. When the locking accessory 162 moves away from the connector, the locking accessory 162 separates from the connector. At this time, the locking accessory 162 releases the confinement of the connector, allowing the connector to be moved out of the slot 1151. The locking accessory 162 can be moved away from the connector by the actuating member 161, or it can be moved away from the connector by the resetting member 13 in the following embodiment. The method of limiting and unlocking the connector using the actuating member 161 and locking accessory 162 in this solution is simple and helps to simplify the structure of the locking and releasing structure 16.

[0109] Optionally, the actuating element 161 includes a handle 1611 and a cam 1612 connected to each other. The hub surface of the cam 1612 abuts against the lock accessory 162. When the handle 161 is turned, the cam 1612 is driven to rotate, so that the cam 1612 drives the lock accessory 162 to move.

[0110] Please refer to Figure 6 In one embodiment of this application, the lock-release structure 16 further includes a reset member 163, which acts between the mounting bracket 11 and the lock accessory 162 to drive the lock accessory 162 out of the slot 1151.

[0111] In this embodiment, the actuating member 161 can drive the locking accessory 162 to move towards the connector. After releasing the actuating member 161, the locking accessory 162 can move away from the connector under the action of the resetting member 163 to release the lock on the connector, allowing the connector to enter and exit the slot 1151, thus enabling the assembly and disassembly of the laser 20. The resetting member 163 can be an elastic element such as a spring, or a magnetic attraction or repulsion structure. For example, the resetting member 163 includes a first magnetic element and a second magnetic element arranged opposite to each other. The first magnetic element is located on the locking accessory 162, and the second magnetic element is located on the mounting bracket 11 and on the side of the locking accessory 163 away from the connector. The magnetic poles of the first and second magnetic elements are opposite. When the actuating member 161 is released, the magnetic attraction between the first and second magnetic elements drives the locking accessory 162 to move away from the connector to release the lock. In addition to locking the connector; alternatively, a second magnetic element is provided on the mounting bracket 11 and located on the side of the locking accessory 163 facing the connector. The magnetic poles of the first and second magnetic elements are the same when they are opposite each other. When the actuating member 161 is released, the magnetic repulsion between the first and second magnetic elements drives the locking accessory 162 to move away from the connector to release the lock on the connector. In this configuration, the reset member 163 can provide a force for the separation of the limiting part 3322 from the connector, thereby improving the smoothness of the separation of the locking accessory 162 from the connector.

[0112] Optionally, multiple reset members 163 can be provided along the length of the lock accessory 162, which helps to improve the stability of the lock accessory 162 abutting against the reset members 163.

All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
