[0045] When the control line 32 is in the slack state, the second wiring wheel 33 will rotate under the drive of the torsion spring, so that the control line 32 is wound around the outside of the second wiring wheel 33, so that the control line 32 is in a taut state; the second wiring wheel 33 is rotatably connected to the top of the laser box 34, and a limit rod 36 is provided inside the laser box 34, and the limit rod 36 is slidably connected to the sliding plate 37, and a display 40 and an integrated control board 41 are provided on the top of the device body 1, and the bottoms of the display 40 and the integrated control board 41 are connected to the detection mechanism;

[0048] When the laser box 34 moves to the specified position, the driving motor 11 rotates in the opposite direction, so that the first ratchet 12 and the second ratchet 13 are disconnected. After the first ratchet 12 and the second ratchet 13 are disconnected, the second ratchet 13 will retreat under the drive of the spring shaft 14 to avoid driving the first sprocket 15 and the second sprocket 17 to rotate. At this time, the driving motor 11 will drive the third sprocket 22 to rotate, so that the third sprocket 22 drives the fourth sprocket 24 and the square block 26 to rotate through the second chain 23, and then the electric push rod 25 is started, so that the electric push rod 25 drives the square block 26 to move, so that the square block 26 engages with the card slot 27, so that the card slot 27 drives the first bevel gear 29 to rotate, so that the first bevel gear 29 drives the second bevel gear 30 to rotate, so that the second bevel gear 30 drives the first wiring wheel 31 to rotate, so that the first wiring wheel 31 rotates to shrink the control line 32;

When the sliding plate 37 moves up and down, the laser therapy head 38 will also move up and down, so as to release weak laser therapy to the designated treatment position of the patient;

[0050] When the laser therapy head 38 releases weak laser therapy, since the laser box 34 is connected to the circuit connector 9 through the transmission line 10, the transmission line 10 will transmit data and energy inside the laser box 34, so that the laser therapy head 38 and the laser detection head 39 can work.

[0051] Working principle: When using the handheld laser therapy device, first connect the main line connector 4 to the connecting circuit of other devices, so that the analysis processor 6, the transmitter 7, the Internet connector 8, and the circuit connector 9 in the detection mechanism can communicate with other medical devices or detection devices, and then start the drive motor 11, so that the drive motor 11 rotates in the positive direction to drive the first ratchet 12 and the second ratchet 13 provided inside the first drive mechanism to engage, so that the second ratchet 13 drives the first sprocket 15 and the second sprocket 17 to rotate through the spring shaft 14, so that the first sprocket 15 and the second sprocket 17 simultaneously drive the first reciprocating screw 18 to rotate, so that the first reciprocating screw 18 drives the screw sleeve 19 and the laser box 34 to move, thereby adjusting the position of the laser box 34;

[0052] When the laser box 34 moves to the specified position, the driving motor 11 rotates in the opposite direction, so that the first ratchet 12 and the second ratchet 13 are disconnected. After the first ratchet 12 and the second ratchet 13 are disconnected, the second ratchet 13 will retreat under the drive of the spring shaft 14 to avoid driving the first sprocket 15 and the second sprocket 17 to rotate. At this time, the driving motor 11 will drive the third sprocket 22 to rotate, so that the third sprocket 22 drives the fourth sprocket 24 and the square block 26 to rotate through the second chain 23, and then the electric push rod 25 is started, so that the electric push rod 25 drives the square block 26 to move, so that the square block 26 engages with the card slot 27, so that the card slot 27 drives the first bevel gear 29 to rotate, so that the first bevel gear 29 drives the second bevel gear 30 to rotate, so that the second bevel gear 30 drives the first wiring wheel 31 to rotate, so that the first wiring wheel 31 rotates to shrink the control line 32;

[0053] When the first wiring wheel 31 contracts the control line 32, the second wiring wheel 33 in the lifting mechanism arranged on the top of the laser box 34 will also rotate synchronously, so that the second wiring wheel 33 drives the second reciprocating screw 35 to rotate, so that the second reciprocating screw 35 drives the sliding plate 37 to move up and down. When the sliding plate 37 moves up and down, the laser therapy head 38 will also move up and down, so as to release weak laser therapy to the designated treatment position of the patient;

[0054] When the laser therapy head 38 releases weak laser therapy, since the laser box 34 is connected to the circuit connector 9 through the transmission line 10, the transmission line 10 will transmit data and energy inside the laser box 34, so that the laser therapy head 38 and the laser detection head 39 can work. At the same time, the data transmitted by the laser detection head 39 is transmitted to the detection mechanism for processing by the analysis processor 6, and then transmitted to the Internet connector 8, the transmitter 7 and other devices, so that other Internet devices can receive the data.
