Description

Technical Field

[0001] This application relates to the technical field of semiconductor devices, and particularly to a handheld portable semiconductor laser device. Background Art

[0002] Semiconductor laser beauty devices are a type of product widely favored in the current market. Semiconductor laser beauty devices achieve precise wavelength control through semiconductor laser chips. With the advantages of monochromaticity and directivity of semiconductor lasers, their energy density can reach 30 - 100 mW / cm², and they can accurately deliver light energy of a specific wavelength to the target area while ensuring the safety of the epidermis (the epidermis temperature is controlled within 38°C).

[0003] Currently, a handheld semiconductor laser beauty device with the publication number CN215349421U includes a fixed frame. Inside the fixed frame, there is a beauty device housing. An installation groove is opened inside the beauty device housing. The inner wall of the installation groove is fixedly connected with an electric push rod. One end of the electric push rod is fixedly connected with a semiconductor laser generator. The lower surface of the fixed frame is fixedly connected with a handle rod.

[0004] Regarding the above - related technology, the size of the handle rod is fixed. Usually, the palm sizes of users are different. If the palm size is larger while the handle size is smaller, the user will feel uncomfortable when holding it, and the fingers may bend too much, resulting in fatigue or even pain after long - term use. If the palm size is smaller while the handle size is larger, the user is likely to hold the handle unsteadily and it is difficult to touch the buttons during operation, resulting in a reduced sense of control and affecting the user's operation accuracy. Thus, the user experience is reduced. Summary of the Invention

[0005] In order to facilitate the grasping of the handle rod by different hand sizes and improve the user experience, this application provides a handheld portable semiconductor laser device.

[0006] The handheld portable semiconductor laser device provided by this application adopts the following technical solutions: A handheld portable semiconductor laser device, comprising: A main body, including an installation shell, a handle, and a battery module. A laser module is installed inside the installation shell. One side of the handle is connected to the installation shell, and the other end is connected to the battery module. A driving button is installed on the handle, and the driving button is used to control the laser module to emit laser. The battery module is used to supply power to the laser module. A guardrail is further provided near the emission end of the laser module on the handle. One end of the guardrail is fixedly connected to the installation shell, and the other end is fixedly connected to the battery module; The telescopic component includes a rotating ring, a transmission member, and a telescopic member. The rotating ring is coaxially and rotatably connected to the outside of the handle. The transmission member and the telescopic member are both installed inside the handle. One end of the transmission member is connected to the rotating ring, and the other end is connected to the telescopic member. When the rotating ring rotates, the telescopic member is driven by the transmission member to drive the handle to expand and contract. The heat dissipation component includes a heat dissipation member and a linkage member. The heat dissipation member is installed on one side of the mounting shell close to the laser module. One end of the linkage member is connected to the guardrail, and the other end is connected to the heat dissipation member. When the guardrail contracts together with the handle, the linkage member drives the heat dissipation member to dissipate heat from the laser module.

[0007] By adopting the above technical solution, when the user is using it, the user first drives the rotating ring to rotate. The rotation of the rotating ring drives the telescopic member to drive the handle to extend until the length of the handle matches the size of the hand shape. Then the user holds the handle and presses the drive button to operate.

[0008] At the same time, during the telescopic process of the handle, the guardrail telescopic synchronously with the handle. When the guardrail contracts synchronously, the heat dissipation member is driven synchronously by the linkage component to dissipate heat from the laser module, avoiding inconvenience caused by overheating of the laser module when the user is using it.

[0009] After the user finishes using it, at this time, the rotating ring is rotated in the reverse direction. The reverse rotation of the rotating ring drives the telescopic member to drive the handle to contract, reducing the distance between the mounting shell and the battery module, thereby optimizing the storage space of the main body and making the main body more convenient to store.

[0010] By using the cooperation of the telescopic handle and the heat dissipation component, not only is the handle suitable for the size of the user's hand shape during the user's use process, but also the heat dissipation member can be turned on for heat dissipation, making the user experience better during the use process.

[0011] Optionally, the handle includes a fixed handle and a telescopic handle. The fixed handle is fixedly connected to the battery module. The telescopic handle is fixedly connected to the mounting shell. The telescopic handle is inserted into the fixed handle. The rotating ring is rotatably connected to the fixed handle. The transmission member and the telescopic member are both installed inside the fixed handle, and the telescopic member is fixedly connected to the telescopic handle.

[0012] By adopting the above technical solution, when the rotating ring is rotated, the rotating ring drives the telescopic member to expand and contract inside the fixed handle and the telescopic handle through the transmission member, thereby controlling the distance of the telescopic handle inside the fixed handle, and further controlling the length of the handle.

[0013] Optionally, the transmission member includes a driving gear, a transmission gear, and a driven gear. The driving gear is fixedly connected to the rotating ring. The transmission gear is rotatably connected to the fixed handle, and one side of the transmission gear meshes with the driving gear, and the other side meshes with the driven gear. The driven gear is coaxially and fixedly connected to the telescopic member to drive the telescopic member to expand and contract.

[0014] By adopting the above technical solution, driving the rotating ring to rotate, the rotation of the rotating ring drives the driving gear to rotate, the rotation of the driving gear drives the transmission gear to rotate, the rotation of the transmission gear drives the driven gear to rotate, and the rotation of the driven gear drives the telescopic member to expand and contract.

[0015] Optionally, the telescopic member includes a fixed cylinder, a driving shaft, and a telescopic cylinder. The fixed cylinder is fixedly connected inside the fixed handle. The driving shaft is coaxially and rotatably connected to the fixed cylinder. The telescopic cylinder is coaxially sleeved inside the fixed cylinder, and the telescopic cylinder is threadedly connected to the driving shaft.

[0016] By adopting the above technical solution, when the driven gear rotates, the rotation of the driven gear drives the driving shaft to rotate. The rotation of the driving shaft drives the telescopic cylinder to move along the axis direction of the fixed cylinder inside the fixed cylinder, so that the telescopic cylinder changes the distance extending out of the fixed cylinder, thereby adjusting the length of the telescopic member and achieving the effect of controlling the expansion and contraction of the telescopic member.

[0017] Optionally, a primary screw cylinder is sleeved on the driving shaft. A primary limiting groove is formed in the driving shaft along its own axis direction. A primary limiting block is fixedly connected to the primary screw cylinder along its own axis direction. The primary limiting block is inserted into the primary limiting groove. A primary extension cylinder is coaxially sleeved inside the telescopic cylinder, and the primary extension cylinder is threadedly connected to the primary screw cylinder.

[0018] By adopting the above technical solution, when the driving shaft rotates, the driving shaft can control the telescopic cylinder to expand and contract. At the same time, the driving shaft uses the limitation of the primary limiting groove and the primary limiting block, so that the driving shaft can rotate synchronously with the primary screw cylinder. During the rotation of the primary screw cylinder, the primary extension cylinder is driven to move along the axis direction of the telescopic cylinder inside the telescopic cylinder, so that the primary extension cylinder changes the distance extending out of the telescopic cylinder, thereby increasing the extended length of the telescopic member and achieving the effect of extending the expansion and contraction length of the telescopic member.

[0019] Optionally, a secondary screw cylinder is sleeved on the primary screw cylinder. A secondary limiting groove is formed in the primary screw cylinder along its own axis direction. A secondary limiting block is fixedly connected to the secondary screw cylinder along its own axis direction. The secondary limiting block is inserted into the secondary limiting groove. A secondary extension cylinder is coaxially sleeved inside the primary screw cylinder, and the secondary extension cylinder is threadedly connected to the secondary screw cylinder. One side of the secondary extension cylinder away from the driving shaft is fixedly connected with an extension rod.

[0020] By adopting the above technical solution, when the primary screw barrel rotates, the primary screw barrel and the secondary screw barrel rotate synchronously by means of the limitation of the secondary limiting groove and the secondary limiting block. The rotation of the secondary screw barrel drives the secondary extension barrel to move along the axis direction of the primary extension barrel inside the primary extension barrel, so that the distance that the secondary extension barrel penetrates out of the primary extension barrel is changed. During the rotation of the drive shaft, the distance that the telescopic barrel penetrates out of the fixed barrel, the distance that the primary extension barrel penetrates out of the telescopic barrel, and the distance that the secondary extension barrel penetrates out of the primary extension barrel can be adjusted synchronously, making the telescopic of the telescopic member more efficient and the structure of the telescopic member more compact.

[0021] Optionally, a stress rod is installed at one end of the extension rod away from the drive shaft. One end of the stress rod away from the extension rod is fixedly connected to the mounting shell. The diameter of the stress rod is larger than that of the extension rod. A reinforcing cylinder is sleeved on the stress rod. Reinforcing racks are symmetrically arranged on both sides of the extension rod. A reinforcing gear is rotatably connected to the reinforcing cylinder. A fixed rack is fixedly connected to the fixed handle. The reinforcing rack and the fixed rack are arranged in parallel. The reinforcing gear is located between the reinforcing rack and the fixed rack. One side of the reinforcing gear meshes with the reinforcing rack, and the other side meshes with the fixed rack.

[0022] By adopting the above technical solution, since the diameter of the extension rod is small, in order to reduce the stress on the mounting shell, a stress rod is provided. Since the diameter of the stress rod is larger than that of the extension rod, the damage to the stress rod and the mounting shell during the telescopic process can be reduced.

[0023] The setting of the reinforcing cylinder can increase the connection stability between the extension rod and the stress rod. At the same time, when the extension rod and the stress rod are telescoping, the reinforcing rack on the extension rod moves upward, driving the reinforcing gear to rotate and move upward at the same time. As the extension rod moves upward continuously, the contact positions of the reinforcing rack and the reinforcing gear change continuously, making the contact point of the reinforcing rack and the reinforcing gear more towards the middle part of the extension rod, making the connection between the extension rod and the reinforcing cylinder more stable, and further making the structure of the extension rod and the stress rod more stable during the elongation process.

[0024] Optionally, heat dissipation holes are provided on the mounting shell. The heat dissipation member includes a rotating rod and heat dissipation fins. The rotating rod is rotatably connected to the inner wall of the heat dissipation hole. The heat dissipation fins are installed in the heat dissipation hole and are fixedly connected to the rotating rod.

[0025] By adopting the above technical solution, when the user uses the semiconductor laser device, the laser module in the mounting shell works. At this time, the laser module needs to dissipate heat, so the rotating rod is controlled to rotate to make the heat dissipation fins in the open state, facilitating the heat dissipation of the laser module in the mounting shell.

[0026] When the user has finished using it, the semiconductor laser device needs to be stored at this time. Therefore, it is necessary to control the rotation of the rotating rod so that the heat dissipation blades are in a closed state, reducing the entry of external dust and impurities and extending the service life of the laser module.

[0027] Optionally, the guardrail includes a fixed rail and a telescopic rail. The fixed rail is fixedly connected to the battery module, the telescopic rail is fixedly connected to the mounting shell, the telescopic rail is arranged in the fixed rail, one end of the linkage is mounted on the fixed rail, and the other end is connected to the rotating rod, so that when the fixed rail and the telescopic rail move relative to each other, the linkage drives the rotating rod to rotate.

[0028] By adopting the above technical solution, when the handle is telescoped, the handle drives the telescopic rail to slide in the fixed rail, so that the fixed rail and the telescopic rail can be telescoped synchronously, and the guardrail can be telescoped synchronously. While the fixed rail and the telescopic rail are telescoping synchronously, the rotating rod is synchronously driven to rotate by the linkage.

[0029] Thus, when the user adjusts the handle for use, through the cooperation of the fixed rail, the telescopic rail and the linkage, the heat dissipation blades are synchronously controlled to open, facilitating the heat dissipation of the laser module during the user's use process.

[0030] When the user adjusts the handle for storage, through the cooperation of the fixed rail, the telescopic rail and the linkage, the heat dissipation blades are also synchronously controlled to close, facilitating the user to store the laser module more conveniently.

[0031] Optionally, the linkage includes a rotating gear and a driving rack. The rotating gear is coaxially and fixedly connected to the rotating rod, one end of the driving rack is fixedly connected to the fixed rail, and the other end extends into the mounting shell and meshes with the rotating gear.

[0032] By adopting the above technical solution, when the guardrail is telescoped, the driving rack and the rotating gear are synchronously driven to move relative to each other, so that the driving rack drives the rotating gear to rotate. The rotating gear rotates to synchronously drive the rotating rod to rotate, and the rotation of the rotating rod further controls the opening and closing of the heat dissipation blades.

[0033] In summary, the present application includes at least one of the following beneficial technical effects: Through the cooperation of the installation shell, handle, battery module, laser module, drive button, guardrail, rotating ring, transmission member, telescopic member, heat dissipation member and linkage member, when the user uses it, the rotation of the rotating ring drives the telescopic member to drive the handle to extend, so that the length of the handle matches the size of the user's hand shape. At the same time, during the telescopic process of the handle, when the guardrail contracts synchronously, the heat dissipation member is synchronously driven by the linkage assembly to dissipate heat from the laser module, avoiding inconvenience in use caused by overheating of the laser module when the user uses it. After the user finishes using it, rotate the rotating ring in the reverse direction. The reverse rotation of the rotating ring drives the telescopic member to drive the handle to contract, reducing the distance between the installation shell and the battery module, thereby optimizing the storage space of the main body and making the main body more convenient to store; Through the cooperation of the fixed handle, telescopic handle, driving gear, transmission gear, driven gear and telescopic member, driving the rotation of the rotating ring can drive the telescopic member to expand and contract; Through the cooperation of the fixed cylinder, drive shaft, telescopic cylinder, primary screw cylinder, primary limit groove, primary limit block, primary extension cylinder, secondary screw cylinder, secondary screw cylinder, secondary limit groove, secondary limit block and secondary extension cylinder, the expansion and contraction of the telescopic member is more efficient, and the structure of the telescopic member is more compact.

[0044] The following is a further detailed description of this application in conjunction with the attached Figures 1-9 drawings.

[0045] The embodiment of this application discloses a handheld portable semiconductor laser device.

[0046] Embodiment 1 Referring to Figure 1 and Figure 2 , the handheld portable semiconductor laser device includes a main body 1, a telescopic assembly 2 and a heat dissipation assembly 3. The main body 1 includes an installation shell 11, a handle 12 and a battery module 13. A laser module is installed in the installation shell 11. One side of the handle 12 is connected to the installation shell 11, and the other end is connected to the battery module 13. A guardrail 4 is further provided near the emission end of the laser module on the handle 12. One end of the guardrail 4 is fixedly connected to the installation shell 11, and the other end is fixedly connected to the battery module 13. The telescopic assembly 2 includes a rotating ring 21, a transmission part 22 and a telescopic part 23. The rotating ring 21 is coaxially and rotatably connected to the outside of the handle 12. The transmission part 22 and the telescopic part 23 are both installed in the handle 12, and one end of the transmission part 22 is connected to the rotating ring 21, and the other end is connected to the telescopic part 23. The heat dissipation assembly 3 is installed on one side of the installation shell 11 close to the laser module to dissipate heat from the laser module. When the rotating ring 21 rotates, the transmission part 22 drives the telescopic part 23 to drive the handle 12 to expand and contract, so as to facilitate the holding of the handle 12 rod by different hand sizes and improve the user experience.

[0047] The battery module 13 is used to supply power to the laser module. A driving button 14 is installed on the handle 12. When the user holds the handle 12, pressing the driving button 14 controls the laser module to emit laser light.

[0048] The handle 12 includes a fixed handle 121 and a telescopic handle 122. The fixed handle 121 is fixedly connected to the battery module 13, and the telescopic handle 122 is fixedly connected to the mounting shell 11. A sliding groove for inserting the telescopic handle 122 is formed in the fixed handle 121. The telescopic handle 122 is inserted into the sliding groove of the fixed handle 121. The telescopic member 23 is telescoped within the fixed handle 121 and the telescopic handle 122, thereby controlling the distance of the telescopic handle 122 within the fixed handle 121, and further controlling the length of the handle 12.

[0049] Referring to Figures 2-4 , the rotating ring 21 is rotatably connected to the fixed handle 121. The transmission member 22 and the telescopic member 23 are both installed in the fixed handle 121. The transmission member 22 in this embodiment includes a driving gear 221, a transmission gear 222, and a driven gear 223. In other embodiments, a belt drive or a chain drive may also be used as the transmission method. However, the gear drive in this embodiment is more stable and saves installation space.

[0050] The driving gear 221 is fixedly connected to the rotating ring 21. The transmission gear 222 is rotatably connected to the fixed handle 121. One side of the transmission gear 222 meshes with the driving gear 221, and the other side meshes with the driven gear 223. And the driven gear 223 is coaxially and fixedly connected to the telescopic member 23. By driving the rotation of the rotating ring 21, the rotation of the rotating ring 21 drives the driving gear 221 to rotate. The rotation of the driving gear 221 drives the transmission gear 222 to rotate. The rotation of the transmission gear 222 drives the driven gear 223 to rotate. The power provided by the rotation of the driven gear 223 is used to drive the telescopic member 23 to rotate.

[0051] Referring to Figure 5 and Figure 6 , the telescopic member 23 in this embodiment includes a fixed cylinder 231, a driving shaft 232, and a telescopic cylinder 233. The fixed cylinder 231 is fixedly connected within the fixed handle 121. The driving shaft 232 is coaxially and rotatably connected to the fixed cylinder 231. The telescopic cylinder 233 is coaxially sleeved within the fixed cylinder 231, and the telescopic cylinder 233 is threadedly connected to the driving shaft 232. The driven gear 223 is coaxially and fixedly connected to the driving shaft 232.

[0052] When the user drives the rotation of the rotating ring 21, the rotation of the rotating ring 21 drives the driving gear 221 to rotate. The rotation of the driving gear 221 drives the transmission gear 222 to rotate. The rotation of the transmission gear 222 drives the driven gear 223 to rotate. The rotation of the driven gear 223 drives the driving shaft 232 to rotate. The rotation of the driving shaft 232 drives the telescopic cylinder 233 to move along the axis direction of the fixed cylinder 231 within the fixed cylinder 231, so that the telescopic cylinder 233 changes the distance of protruding out of the fixed cylinder 231, thereby adjusting the length of the telescopic member 23, achieving the effect of controlling the telescopic of the telescopic member 23, and further being able to achieve the adjustment of the length of the handle 12.

[0053] In an alternative embodiment, a primary screw barrel 5 is sleeved on the drive shaft 232. A primary limiting groove 51 is formed in the drive shaft 232 along its own axis direction. A primary limiting block 52 is fixedly connected to the primary screw barrel 5 along its own axis direction. The primary limiting block 52 is inserted into the primary limiting groove 51. A primary extension barrel 53 is coaxially sleeved in the telescopic barrel 233. The primary extension barrel 53 is threadedly connected to the primary screw barrel 5. Through the cooperation of the primary screw barrel 5 and the primary extension barrel 53, when the drive shaft 232 rotates to drive the telescopic barrel 233 to expand and contract, the primary extension barrel 53 will also be synchronously driven to expand and contract in the primary screw barrel 5, achieving the effect of increasing the telescopic stroke, and making the rotation ring 21 control the handle 12 to expand and contract more sensitively.

[0054] When the drive shaft 232 rotates, the drive shaft 232 can control the telescopic barrel 233 to expand and contract. At the same time, the drive shaft 232 is limited by the primary limiting groove 51 and the primary limiting block 52, so that the drive shaft 232 can rotate synchronously with the primary screw barrel 5. During the rotation of the primary screw barrel 5, the primary extension barrel 53 is driven to move in the axial direction of the telescopic barrel 233 in the telescopic barrel 233, so that the distance that the primary extension barrel 53 penetrates out of the telescopic barrel 233 is changed, thereby increasing the extended length of the telescopic member 23.

[0055] A secondary screw barrel 6 is also sleeved on the primary screw barrel 5. A secondary limiting groove 61 is formed in the primary screw barrel 5 along its own axis direction. A secondary limiting block 62 is fixedly connected to the secondary screw barrel 6 along its own axis direction. The secondary limiting block 62 is inserted into the secondary limiting groove 61. A secondary extension barrel 63 is coaxially sleeved in the primary screw barrel 5, and the secondary extension barrel 63 is threadedly connected to the secondary screw barrel 6. An extension rod 7 is fixedly connected to the side of the secondary extension barrel 63 away from the drive shaft 232.

[0056] When the drive shaft 232 rotates to drive the telescopic barrel 233 to expand and contract, not only will the primary extension barrel 53 be synchronously driven to expand and contract in the primary screw barrel 5, but also the secondary extension barrel 63 will be synchronously driven to expand and contract in the secondary screw barrel 6, achieving the effect of further increasing the telescopic stroke.

[0057] When the primary screw barrel 5 rotates, the primary screw barrel 5 and the secondary screw barrel 6 rotate synchronously due to the limitation of the secondary limiting groove 61 and the secondary limiting block 62. The rotation of the secondary screw barrel 6 drives the secondary extension barrel 63 to move in the axial direction of the primary extension barrel 53 in the primary extension barrel 53, so that the distance that the secondary extension barrel 63 penetrates out of the primary extension barrel 53 is changed. When the drive shaft 232 rotates, the distance that the telescopic barrel 233 penetrates out of the fixed barrel 231, the distance that the primary extension barrel 53 penetrates out of the telescopic barrel 233, and the distance that the secondary extension barrel 63 penetrates out of the primary extension barrel 53 can be synchronously adjusted, making the expansion and contraction of the telescopic member 23 more efficient and the structure of the telescopic member 23 more compact.

[0058] Reference Figure 1 As shown in Figure 1 , the guardrail 4 includes a fixed rail 41 and a telescopic rail 42. The fixed rail 41 is fixedly connected to the battery module 13, and the telescopic rail 42 is fixedly connected to the mounting shell 11. A sliding groove is also provided on the fixed rail 41, and the telescopic rail 42 is inserted into the sliding groove of the fixed rail 41. When the fixed handle 121 and the telescopic handle 122 are telescoped, the telescopic rail 42 is driven to slide within the fixed rail 41, so that the fixed rail 41 and the telescopic rail 42 can be telescoped synchronously with the handle 12.

[0059] Reference Figure 1 and Figure 6 As shown in Figure 1 and Figure 6 , the heat dissipation component 3 in this embodiment includes a heat dissipation member 31 and a linkage member 32. The heat dissipation member 31 is installed on one side of the mounting shell 11 close to the laser module. The heat dissipation member 31 includes a rotating rod 311 and heat dissipation blades 312. Heat dissipation holes 15 are provided on both sides of the mounting shell 11 close to the laser module. The rotating rod 311 is rotatably connected to the inner wall of the heat dissipation hole 15, and the heat dissipation blades 312 are installed in the heat dissipation holes 15 and are fixedly connected to the rotating rod 311. By using the cooperation between the heat dissipation blades 312 and the rotating rod 311, the opening for heat dissipation and the closing for storage of the heat dissipation blades 312 are controlled.

[0060] The linkage member 32 includes a rotating gear 321 and a driving rack 322. The rotating gear 321 is coaxially and fixedly connected to the rotating rod 311. One end of the driving rack 322 is fixedly connected to the fixed rail 41, and the other end extends into the mounting shell 11 and meshes with the rotating gear 321. When the guardrail 4 is telescoped, the driving rack 322 and the rotating gear 321 are synchronously driven to move relative to each other, so that the driving rack 322 drives the rotating gear 321 to rotate. The rotation of the rotating gear 321 synchronously drives the rotating rod 311 to rotate, and the rotation of the rotating rod 311 further controls the opening and closing of the heat dissipation blades 312.

[0061] When the user uses the semiconductor laser device, the handle 12 is extended. At this time, the driving rack 322 and the rotating gear 321 move relative to each other, so that the driving rack 322 drives the rotating gear 321 to rotate. The rotation of the rotating gear 321 drives the rotating rod 311 to rotate, and the rotation of the rotating rod 311 further controls the rotation of the heat dissipation blades 312, so that the heat dissipation blades 312 are in an open state. At this time, the laser module in the mounting shell 11 operates, so the laser module needs to dissipate heat. The opening of the heat dissipation blades 312 facilitates the heat dissipation of the laser module in the mounting shell 11.

[0062] When the user has finished using it, the handle 12 shortens. At this time, the driving rack 322 and the rotating gear 321 have a relative movement in the reverse direction, causing the driving rack 322 to drive the rotating gear 321 to rotate in the reverse direction. The reverse rotation of the rotating gear 321 drives the rotating rod 311 to rotate in the reverse direction, and the reverse rotation of the rotating rod 311 further controls the reverse rotation of the heat dissipation blades 312, so that the heat dissipation blades 312 are in a closed state. At this time, it is necessary to store the semiconductor laser device. The heat dissipation blades 312 in the closed state can reduce the entry of external dust and impurities and extend the service life of the laser module.

[0063] The implementation principle of a handheld portable semiconductor laser device according to an embodiment of the present application is as follows: When the user is using it, the user first drives the rotating ring 21 to rotate. The rotation of the rotating ring 21 drives the driving gear 221 to rotate. The rotation of the driving gear 221 drives the transmission gear 222 to rotate. The rotation of the transmission gear 222 drives the driven gear 223 to rotate. The rotation of the driven gear 223 drives the driving shaft 232 to rotate. The rotation of the driving shaft 232 drives the primary screw cylinder 5 and the secondary screw cylinder 6 to rotate synchronously, so that the telescopic cylinder 233, the primary extension cylinder 53, and the secondary extension cylinder 63 extend synchronously, and then drive the telescopic handle 122 to penetrate out of the fixed handle 121, so that the handle 12 extends until the length of the handle 12 matches the size of the hand shape. Then, holding the handle 12 and pressing the driving button 14 can perform the operation.

[0064] During the process of the handle 12 extending, the telescopic bar 42 also penetrates out of the fixed bar 41. At this time, the driving rack 322 and the rotating gear 321 have a relative movement, causing the driving rack 322 to drive the rotating gear 321 to rotate. The rotation of the rotating gear 321 drives the rotating rod 311 to rotate. The rotation of the rotating rod 311 further controls the rotation of the heat dissipation blades 312, so that the heat dissipation blades 312 are in an open state, facilitating the heat dissipation of the laser module in the installation shell 11 during the working process.

[0065] When the user is using it and rotates the rotating ring 21 to a suitable hand shape size, it is not only convenient for users with different hand sizes to hold the handle 12 rod, but also opens the heat dissipation blades 312, enabling the laser module to dissipate heat, avoiding inconvenience caused by overheating of the laser module when the user is using it.

[0066] After the user finishes using it, at this time, the rotating ring 21 is rotated reversely. The reverse rotation of the rotating ring 21 drives the reverse rotation of the driving gear 221. The reverse rotation of the driving gear 221 drives the reverse rotation of the transmission gear 222. The reverse rotation of the transmission gear 222 drives the reverse rotation of the driven gear 223. The reverse rotation of the driven gear 223 drives the reverse rotation of the driving shaft 232. The reverse rotation of the driving shaft 232 drives the synchronous reverse rotation of the primary screw barrel 5 and the secondary screw barrel 6, so that the telescopic cylinder 233, the primary extension cylinder 53 and the secondary extension cylinder 63 contract synchronously, and then drives the telescopic handle 122 to contract into the fixed handle 121, so that the handle 12 is shortened until the length of the handle 12 is reduced to the shortest, optimizing the storage space of the portable semiconductor laser device and facilitating carrying.

[0067] During the process of shortening the handle 12, the telescopic bar 42 contracts into the fixed bar 41. At this time, the driving rack 322 and the rotating gear 321 move in the opposite direction, so that the driving rack 322 drives the rotating gear 321 to rotate reversely. The rotation of the rotating gear 321 drives the reverse rotation of the rotating rod 311. The reverse rotation of the rotating rod 311 further controls the reverse rotation of the heat dissipation fins 312, so that the heat dissipation fins 312 are in a closed state, reducing the distance between the installation shell 11 and the battery module 13, thereby optimizing the storage space of the main body 1. The heat dissipation fins 312 in a closed state can reduce the entry of external dust and impurities, extend the service life of the laser module, and make the portable semiconductor laser device more convenient for storage.

[0068] Embodiment 2 Refer to Figures 7-9 , the difference between Embodiment 2 and Embodiment 1 is that a stress rod 8 is installed at one end of the extension rod 7 far from the driving shaft 232. Due to the sleeving of the telescopic cylinder 233, the primary extension cylinder 53 and the secondary extension cylinder 63, the diameter of the extension rod 7 is small. Therefore, the extension rod 7 is prone to stress damage with the installation shell 11 during the telescopic process. In order to reduce the stress on the installation shell 11, a stress rod 8 is installed at one end of the extension rod 7 far from the driving shaft 232. One end of the stress rod 8 far from the extension rod 7 is fixedly connected to the installation shell 11, and the diameter of the stress rod 8 is larger than that of the extension rod 7. Since the diameter of the stress rod 8 is larger than that of the extension rod 7, the damage to the stress rod 8 and the installation shell 11 during the telescopic process can be reduced.

[0069] A reinforcing cylinder 9 is sleeved on the stress rod 8. Reinforcing racks 91 are symmetrically arranged on both sides of the extension rod 7. A reinforcing gear 92 is rotatably connected to the reinforcing cylinder 9. A fixed rack 93 is fixedly connected to the fixed handle 121. The reinforcing racks 91 and the fixed rack 93 are arranged in parallel. The reinforcing gear 92 is located between the reinforcing racks 91 and the fixed rack 93, and one side of the reinforcing gear 92 meshes with the reinforcing rack 91, and the other side meshes with the fixed rack 93.

[0070] The arrangement of the reinforcing cylinder 9 can enhance the stability of the connection between the extension rod 7 and the stress rod 8. Meanwhile, when the extension rod 7 and the stress rod 8 are telescoping, the reinforcing rack 91 on the extension rod 7 moves upward, thereby driving the reinforcing gear 92 to move upward while rotating. As the extension rod 7 moves upward continuously, the contact positions between the reinforcing rack 91 and the reinforcing gear 92 change continuously, making the contact point between the reinforcing rack 91 and the reinforcing gear 92 more towards the middle part of the extension rod 7, making the connection between the extension rod 7 and the reinforcing cylinder 9 more stable. Furthermore, when the extension rod 7 and the stress rod 8 are elongating, the structure among the extension rod 7, the stress rod 8 and the reinforcing cylinder 9 is more stable, extending the service life of the equipment.

[0071] The above are all the preferred embodiments of this application. The protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape and principle of this application shall be covered within the protection scope of this application.
