The free ends of the connecting wire 10 are connected to the positive wire 11 and the negative wire 12. The conductive platform 8 is electrically connected to an output wire 13 that is plugged into the output port 2. The free end of the output wire 13 passes through the first outlet, and the free end of the connecting wire 10 passes through the second outlet. The connecting wire 10 is electrically connected to the circuit board 7. The connecting frame 3 is provided with the same number of fasteners as the connecting wires 10 and in one-to-one correspondence, and the connecting wires 10 are locked or unlocked by the fasteners.

[0029] In the initial state, the output line 13 is not plugged into the output port 2, the spring 9 is in a natural state, the connecting line 10, the positive line 11 and the negative line 12 are all retracted into the winding box 5. When the instrument body 1 is used, the free end of the output line 13 is plugged into the output port 2, the positive line 11, the negative line 12 and the connecting line 10 are pulled out of the winding box 5, the spring 9 is compressed, and then the connecting line 10 is locked by the buckle, the positive line 11 and the negative line 12 are connected to the acupuncture needle or the electrode sheet to fit the patient's skin, and then the instrument is opened. Open the instrument body 1, and ensure normal use through the electrical connection between the output line 13 and the circuit board 7, as well as the electrical connection between the connecting line 10 and the circuit board 7. After use, the connecting line 10 is unlocked by the fastener, and the spring spring 9 is reset to its natural state. The pulled-out positive line 11, negative line 12 and connecting line 10 are automatically retracted into the winding box 5 through elastic potential energy, thereby preventing entanglement. Therefore, when the device of the utility model is in use, it can avoid entanglement between the lines, and the use environment is more tidy and beautiful, and it is easy to use.

[0030] like Figure 3-Figure 5 As shown, the connecting frame 3 is detachably connected to the instrument body 1. In the initial state, the connecting frame 3 is not connected to the instrument body 1. When in use, the connecting frame 3 is connected to the instrument body 1. After use, the connecting frame 3 is disassembled from the instrument body 1, which is not only convenient for transportation and transfer, but also more neat and beautiful.

[0031] like Figure 3-Figure 5As shown, a plurality of fixing rods 14 are provided on the connecting frame 3, the fixing rods 14 are in a vertical direction and fixed on the connecting frame 3, and a plurality of positioning grooves 15, all of which are L-shaped, are provided on the instrument body 1. The number of positioning grooves 15 is the same as the number of fixing rods 14 and corresponds one to one. A positioning rod 16 is slidingly provided on the fixing rod 14 and a return spring 17 is provided between the two. The positioning rod 16 slides in the vertical direction, the return spring 17 is in a vertical direction and its two ends are fixedly connected to the fixing rod 14 and the positioning rod 16 respectively. The positioning rod 16 is L-shaped and is plugged into the positioning groove 15. A guiding slope is constructed on the positioning rod 16.

[0032] In the initial state, the connecting frame 3 is not connected to the instrument body 1, the positioning rod 16 is in the initial position, and the return spring 17 is in the natural state. When in use, the positioning rod 16 corresponds to and is inserted into the positioning groove 15. During this process, the guiding slope first contacts and overlaps the positioning groove 15. Through the transition effect of the guiding slope, the positioning rod 16 is forced to slide to the limit position, the return spring 17 is squeezed, and then the return spring 17 is reset to the natural state, and the positioning rod 16 slides to the initial position. At this time, the positioning rod 16 cannot exit the positioning groove 15 to connect the connecting frame 3 to the instrument body 1. On the contrary, after use, the positioning rod 16 is slid to the limit position, the return spring 17 is squeezed, and the positioning rod 16 is able to exit the positioning groove 15 to disassemble the connecting frame 3 from the instrument body 1. Then, the positioning rod 16 is released, the return spring 17 is reset to the natural state, and the positioning rod 16 slides to the initial position.

[0033] like Figure 8-Figure 9 As shown, the connecting frame 3 is hinged with cover plates 18 of the same number and one-to-one correspondence as the accommodating slots 4, and the accommodating slots 4 are blocked or unlocked by the cover plates 18. The snap fasteners are set on the cover plates 18, and the winding box 5 is slidably set in the accommodating slots 4. The cover plates 18 abut against the winding box 5, and the connecting frame 3 is provided with a locking portion for locking or unlocking the cover plates 18.

[0034] In the initial state, the cover 18 unblocks the receiving slot 4, and the wire winding box 5 is not in the receiving slot 4. When in use, the wire winding box 5 is slid to be completely in the receiving slot 4, the cover 18 is rotated and the receiving slot 4 is blocked, the cover 18 and the wire winding box 5 are in contact and overlapped, and then the cover 18 is locked by the locking part so that the cover 18 cannot be rotated, thereby realizing the installation of the wire winding box 5. Conversely, after use, the cover 18 is unlocked by the locking part, the cover 18 is rotated and the receiving slot 4 is unblocked, and the wire winding box 5 can be slid to exit the receiving slot 4 to realize the disassembly of the wire winding box 5, thereby facilitating the replacement of the wire winding box 5.

[0035] like Figure 8As shown, a torsion spring 19 is provided at the hinge of the cover plate 18 , and both ends of the torsion spring 19 are fixedly connected to the cover plate 18 and the connecting frame 3 respectively.

[0036] In the initial state, the cover 18 unblocks the receiving slot 4, and the torsion spring 19 is in a natural state. When the cover 18 rotates and blocks the receiving slot 4, the torsion spring 19 is squeezed. When the cover 18 is unlocked by the locking portion, the torsion spring 19 returns to its natural state, and the cover 18 automatically unblocks the receiving slot 4, making it more convenient to use.

[0037] like Figure 9 As shown, the locking portion includes a protrusion 20 arranged on the cover plate 18, the protrusion 20 is fixed on the cover plate 18, and a limiting rod 21 is slidably provided on the connecting frame 3. The limiting rod 21 slides in the horizontal direction, and the free end of the limiting rod 21 is provided with a wedge block 22 that contacts and overlaps with the protrusion 20. The wedge block 22 is fixed to the free end of the limiting rod 21, and an extrusion spring 23 is provided between the wedge block 22 and the connecting frame 3 and is sleeved on the limiting rod 21. The extrusion spring 23 is horizontally directed and its two ends are fixedly connected to the wedge block 22 and the connecting frame 3 respectively.

[0038] In the initial state, the limiting rod 21 and the wedge block 22 are both in the initial position, and the extrusion spring 23 is in the natural state. When the cover 18 rotates and blocks the receiving groove 4, the protrusion 20 is driven to move together. The protrusion 20 first contacts and overlaps with the inclined surface of the wedge block 22. Through the transition effect of the inclined surface, the limiting rod 21 and the wedge block 22 are forced to move to the limit position together. The extrusion spring 23 is squeezed, and then the extrusion spring 23 is reset to the natural state. The limiting rod 21 and the wedge block 22 move to the initial position together, and the protrusion 20 contacts and overlaps with the inclined surface of the wedge block 22. The planes of the block 20 and the wedge block 22 come into contact and overlap to lock the cover 18. Conversely, the limit rod 21 and the wedge block 22 are driven to move together to the extreme position, the extrusion spring 23 is squeezed, and due to the loss of the obstruction of the wedge block 22, the cover 18 automatically unblocks the accommodating groove 4 and drives the protrusion 20 to move together. Then, the limit rod 21 and the wedge block 22 are released, the extrusion spring 23 is restored to the natural state, and the limit rod 21 and the wedge block 22 move together to the initial position to unlock the cover 18.

[0039] like Figures 8-10As shown, the latch comprises a slide bar 24 and a guide bar 25 both of which are slidably arranged on the cover plate 18, the slide bar 24 slides in the vertical direction, the guide bar 25 slides in the horizontal direction, a compression spring 26 is provided between the slide bar 24 and the cover plate 18, the compression spring 26 is in a vertical direction and its two ends are fixedly connected to the slide bar 24 and the cover plate 18 respectively, the free end of the slide bar 24 is provided with a pressure plate 27 which is in contact with and overlapped with the connecting line 10, the pressure plate 27 is fixed to the free end of the slide bar 24, the free end of the guide bar 25 is provided with a wedge plate 28 which is in contact with and overlapped with the slide bar 24, the wedge plate 28 is fixed to the free end of the guide bar 25, a fixing spring 29 which is sleeved on the guide bar 25 is provided between the wedge plate 28 and the cover plate 18, the fixing spring 29 is in a horizontal direction and its two ends are fixedly connected to the wedge plate 28 and the cover plate 18 respectively;

[0040] In the initial state, the slide bar 24, the pressure plate 27, the guide rod 25 and the wedge plate 28 are all in the initial position, and the compression spring 26 and the fixed spring 29 are all in the natural state. When in use, the slide bar 24 slides to the limit position, driving the pressure plate 27 to move together until the pressure plate 27 contacts and overlaps with the connecting line 10, and the compression spring 26 is squeezed. In this process, the slide bar 24 first contacts and overlaps with the inclined surface of the wedge plate 28, and through the transition effect of the inclined surface, the guide rod 25 is forced to move to the limit position together with the wedge plate 28, and the fixed spring 29 is squeezed. After that, the fixed spring 29 is reset to the natural state, and the guide bar 24 is released. 25 moves to the initial position together with the wedge plate 28, the slide bar 24 contacts and overlaps the plane of the wedge plate 28, and the slide bar 24 cannot slide to the initial position. The pressure plate 27 applies a resistance force to the connecting line 10, so that the connecting line 10 cannot move, thereby locking the connecting line 10. On the contrary, the guide rod 25 and the wedge plate 28 move to the extreme position together, the fixing spring 29 is squeezed, and the compression spring 26 returns to the natural state. The slide bar 24 and the pressure plate 27 move to the initial position together, and then the guide rod 25 and the wedge plate 28 are released, and the fixing spring 29 returns to the natural state, thereby unlocking the connecting line 10.

[0041] like Figure 8 As shown, the pressure plate 27 is provided with a plurality of rubber protrusions 30 that are in contact with and overlap the connecting wire 10. When the pressure plate 27 applies a resistance force to the connecting wire 10, the setting of the plurality of rubber protrusions 30 can not only prevent the connecting wire 10 from being crushed, but also increase the friction force to prevent the connecting wire 10 from slipping.
