[0013] After the user finishes using it, the rotating ring is reversely rotated, the rotating ring reversely rotates to drive the telescopic member to retract the handle, thereby reducing the distance between the mounting shell and the battery module, so that the storage space of the main body can be optimized, and the main body is more convenient to store.

[0014] The cooperation of the telescopic handle and the heat dissipation assembly not only makes the handle suitable for the size of the user's hand during use, but also enables the heat dissipation member to dissipate heat, so that the user has a better experience during use.

[0020] By adopting the above technical scheme, when the driven gear rotates, the driven gear drives the driving shaft to rotate, the driving shaft drives the telescopic cylinder to move in the axial direction of the fixed cylinder, so that the telescopic cylinder changes the distance penetrating into the fixed cylinder, thereby adjusting the length of the telescopic member, and achieving the effect of controlling the extension and retraction of the telescopic member.

The fixed rail and the telescopic rail are telescoped synchronously, and the linkage synchronously drives the rotating rod to rotate.

[0033] Therefore, during the use of the adjusting handle, the fixed rail, the telescopic rail and the linkage are cooperated to synchronously control the heat dissipation leaves to be opened, so that the laser module is conveniently cooled during the use of the user.

Simultaneously, as the handle extends and retracts, the guardrail retracts in sync, driving the heat dissipation components through the linkage components to cool the laser module, preventing overheating and inconvenience during use. After use, the user rotates the rotating ring in the opposite direction. This reverse rotation causes the telescopic component's drive handle to retract, reducing the distance between the mounting shell and the battery module. This optimizes the storage space of the main unit, making it easier to store. The coordination of the fixed handle, telescopic handle, drive gear, transmission gear, driven gear, and telescopic component drives the rotating ring to rotate, which in turn drives the telescopic component to extend and retract. The coordination of the fixed cylinder, drive shaft, telescopic cylinder, primary screw cylinder, primary limiting groove, primary limiting block, primary extension cylinder, secondary screw cylinder, secondary screw cylinder, secondary limiting groove, secondary limiting block, and secondary extension cylinder makes the telescopic component's extension and retraction more efficient and its structure more compact.

[0071] In the process of elongating the handle 12, the telescopic bar 42 also passes out of the fixed bar 41, at this time the driving rack 322 and the rotating gear 321 have relative motion, so that the driving rack 322 drives the rotating gear 321 to rotate, the rotating gear 321 drives the rotating rod 311 to rotate, the rotating rod 311 rotates to control the heat dissipation leaf 312 to rotate, so that the heat dissipation leaf 312 is in an open state, facilitating the heat dissipation of the laser module in the installation shell 11 during working.

[0072] When the user uses, the rotating ring 21 is rotated to a suitable hand size, which not only facilitates the holding of the handle 12 by different sizes of hands, but also opens the heat dissipation leaf 312, so that the laser module is cooled, avoiding the inconvenience caused by overheating of the laser module during use.

[0073] When the user has finished using the device, the rotating ring 21 is rotated in the reverse direction, which drives the driving gear 221 to rotate in the reverse direction, and the driving gear 221 drives the transmission gear 222 to rotate in the reverse direction, and the transmission gear 222 drives the driven gear 223 to rotate in the reverse direction, and the driven gear 223 drives the driving shaft 232 to rotate in the reverse direction, and the driving shaft 232 drives the primary cylinder 5 and the secondary cylinder 6 to rotate in the reverse direction, thereby driving the telescopic cylinder 233, the primary extension cylinder 53, and the secondary extension cylinder 63 to contract synchronously, and driving the telescopic handle 122 to contract into the fixed handle 121, so that the handle 12 is shortened, and the storage space of the portable semiconductor laser device is optimized, thereby facilitating the carrying of the device.

[0074] During the shortening of the handle 12, the telescopic bar 42 is contracted into the fixed bar 41, and the driving rack 322 and the rotating gear 321 move in the reverse direction, which drives the driving rack 322 to drive the rotating gear 321 to rotate in the reverse direction, and the rotating gear 321 drives the rotating rod 311 to rotate in the reverse direction, and the rotating rod 311 drives the cooling leaf 312 to rotate in the reverse direction, so that the cooling leaf 312 is in a closed state, the distance between the mounting shell 11 and the battery module 13 is reduced, thereby optimizing the storage space of the main body 1, and the cooling leaf 312 in the closed state can reduce the entry of external dust and impurities, prolong the service life of the laser module, and make the portable semiconductor laser device more convenient to store.

[0075] Embodiment 2

[0076] Reference Figures 7-9 The difference between Embodiment 2 and Embodiment 1 is that the stress rod 8 is installed at the end of the extension rod 7 away from the driving shaft 232. Because the diameter of the extension rod 7 is small due to the sleeving of the telescopic cylinder 233, the primary extension cylinder 53, and the secondary extension cylinder 63, the extension rod 7 is prone to stress damage during the telescopic process. In order to reduce the stress on the mounting shell 11, the stress rod 8 is installed at the end of the extension rod 7 away from the driving shaft 232, the end of the stress rod 8 away from the extension rod 7 is fixedly connected with the mounting shell 11, and the diameter of the stress rod 8 is greater than that of the extension rod 7. Because the diameter of the stress rod 8 is greater than that of the extension rod 7, the damage to the stress rod 8 and the mounting shell 11 during the telescopic process is reduced.

[0077] The reinforcing cylinder 9 is sleeved on the stress rod 8, the reinforcing teeth 91 are symmetrically formed on both sides of the extension rod 7, the reinforcing gear 92 is rotatably connected to the reinforcing cylinder 9, the fixed teeth 93 are fixedly connected to the fixed handle 121, the reinforcing teeth 91 and the fixed teeth 93 are parallelly arranged, the reinforcing gear 92 is located between the reinforcing teeth 91 and the fixed teeth 93, one side of the reinforcing gear 92 is engaged with the reinforcing teeth 91, and the other side is engaged with the fixed teeth 93.

[0078] The setting of the reinforcing cylinder 9 can increase the stability of the connection between the extension rod 7 and the stress rod 8, and when the extension rod 7 and the stress rod 8 are in the process of stretching and retracting, the reinforcing rack 91 on the extension rod 7 moves upward, thereby driving the reinforcing gear 92 to rotate and move upward, so that the contact position between the reinforcing rack 91 and the reinforcing gear 92 changes constantly during the continuous upward movement of the extension rod 7, and the contact point between the reinforcing rack 91 and the reinforcing gear 92 is more towards the middle part of the extension rod 7, so that the connection between the extension rod 7 and the reinforcing cylinder 9 is more stable, and the structure among the extension rod 7, the stress rod 8 and the reinforcing cylinder 9 is more stable during the stretching process of the extension rod 7 and the stress rod 8, thereby prolonging the service life of the device.

[0079] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape and principle of the present application should be covered within the protection scope of the present application.
