[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] Example 1: As shown in the attached document Figure 1 To be continued Figure 6 As shown: This utility model provides a wireless microphone with a quick-release structure, comprising: a handheld body 1, a functional module 2 inserted into the top of the handheld body 1, an adjustment knob 6 rotatably connected to the bottom of the rear side wall of the handheld body 1, a transmission control rod 7 rotatably connected to the bottom end face of the handheld body 1, four limiting pins 8 arranged in a circumferential shape on the bottom outer side of the transmission control rod 7, a signal transmission module 5 inserted into the bottom of the handheld body 1, a battery and a signal processing module disposed in the handheld body 1, a pickup head disposed in the functional module 2, and a recessed connecting seat 101 formed in the top end face of the handheld body 1. Two conductive springs 107 are symmetrically installed at the bottom center. Connecting rods 103 are fixedly installed on the connecting seats 101 on both sides of the conductive springs 107. Three sliding holes 102 are arranged in a circular array on the upper surface of the handheld body 1 on the outer top of the connecting seat 101. Positioning pins 3 are slidably connected in the sliding holes 102. A connecting groove 201 is provided in the bottom surface of the functional module 2. Two electrical terminals 202 are symmetrically arranged in the middle of the bottom surface of the connecting groove 201. The bottom of the electrical terminals 202 is connected to the conductive springs 107 in the connecting seat 101 at the top of the handheld body 1. The connecting groove 201... Two symmetrical arc-shaped connecting slots 203 are formed on the top end face. The connecting slots 203 and the top ends of the connecting rods 103 in the connecting seat 101 are inserted and slidably connected. Three limiting holes 204 are formed in a ring array on the outer side of the bottom end face of the functional module 2, corresponding to the sliding holes 102 on the top of the handheld body 1. Electromagnets 4 are fixedly installed in the limiting holes 204. The bottom of the electromagnets 4 and the top end of the positioning pins 3 in the sliding holes 102 attract each other. Specifically, by inserting and sliding the connecting rods 103 into the connecting slots 203, the functional module 2 and the handheld body 1 are initially positioned, avoiding misalignment during assembly. The elastic contact between plate 107 and the power terminal 202 ensures stable circuit conduction and buffers the impact force during assembly. At the same time, when the electromagnet 4 is energized, it attracts the positioning pin 3, causing the positioning pin 3 to insert into the limiting hole 204, completing the secondary locking of the functional module 2. This allows for quick assembly without tools, and the dual positioning structure greatly improves the connection stability between the functional module 2 and the handheld body 1, preventing poor contact caused by shaking during use. After power is cut off, the electromagnet 4 loses its attraction force, and the positioning pin 3 falls back into the sliding hole 102, allowing the functional module 2 to be directly rotated and pulled out, achieving quick disassembly and meeting emergency maintenance needs.

[0018] The handheld main body 1 has an adjustment hole 105 at the bottom of its rear side wall. A symmetrical arc-shaped guide groove 106 is formed in the front side wall of the adjustment hole 105. One end of the guide groove 106 is magnetic. An adjustment knob 6 is rotatably connected to the adjustment hole 105. A limiting slide rod 601, symmetrically arranged on the centrifugal side of the front side wall of the adjustment knob 6, is slidably connected to the guide groove 106. A transmission bevel gear 602 is fixedly connected to the front end of the adjustment knob 6. A driven bevel gear 701 is fixedly connected to the top end of the transmission control rod 7. The driven bevel gear 701 and the transmission bevel gear 602 at the front end of the adjustment knob 6 mesh perpendicularly. A swing block 702 is fixedly connected to the bottom end of the transmission control rod 7. The swing block 702 is cross-shaped. The four ends of the swing block 702 are slidably connected to one end of a limiting pin 8. Sliding fins 801 are symmetrically installed on the outer side wall of the four limiting pins 8 facing the center of the array. The sliding fin 801 is slidably connected to the handheld body 1. A support spring 802 is provided on the side of the sliding fin 801 away from the center of the array. Specifically, by rotating the adjustment knob 6, the vertical meshing of the transmission bevel gear 602 and the driven bevel gear 701 converts the horizontal rotation of the knob into the vertical rotation of the transmission control rod 7, which in turn drives the "+" shaped swing block 702 to rotate. When the swing block 702 rotates, it pushes or pulls the limit pin 8. Combined with the guiding effect of the sliding fin 801, the four limit pins 8 can be extended and retracted synchronously without the need for individual operation, improving the convenience of control. The support spring 802 can push the limit pin 8 to automatically return to its original position when the swing block 702 resets, ensuring the reliability of the structure reset. At the same time, the magnetism at one end of the guide groove 106 can attract the limit slide rod 601, fixing the adjustment knob 6 in a specific position, preventing the limit pin 8 from loosening due to accidental touch during use, and enhancing the stability of the structure lock.

[0019] The handheld main body 1 has a combination groove 104 at its bottom. The combination ring 501 on the top end face of the signal transmitting module 5 is inserted into the combination groove 104. Four limiting grooves 502 are arranged in a ring array on the inner wall of the combination ring 501. The limiting grooves 502 are connected to the ends of the limiting pins 8. Specifically, the insertion and engagement of the combination ring 501 with the combination groove 104 achieves initial positioning of the signal transmitting module 5 and the handheld main body 1, ensuring coaxiality of the two components and preventing the signal transmitting module 5 from shifting and affecting signal transmission. The connection between the end of the limiting pin 8 and the limiting groove 502... The signal transmitting module 5 can be quickly locked and unlocked by the extension and retraction of the limiting pin 8. When the limiting pin 8 extends, it is embedded in the limiting groove 502, which fixes the signal transmitting module 5 on the handheld body 1 to prevent it from falling off. When the limiting pin 8 retracts, it disengages from the limiting groove 502, and the signal transmitting module 5 can be pulled out to complete the quick disassembly. The disassembly and assembly of the signal transmitting module 5 can be achieved without tools, which greatly shortens the maintenance time. In addition, the four limiting grooves 502 of the ring array cooperate with the limiting pin 8 to make the signal transmitting module 5 evenly stressed, the connection more stable, and avoid the module loosening caused by vibration.

[0020] The specific usage and function of this embodiment are as follows: When using this wireless microphone with a quick-release structure, first align the connecting groove 201 at the bottom of the functional module 2 with the connecting seat 101 at the top of the handheld body 1, so that the arc-shaped connecting slot 203 is aligned with the connecting rod 103. Push to complete the initial positioning. At this time, the power post 202 abuts against the conductive spring 107 to power the battery inside the handheld body 1. The electromagnet 4 attracts the positioning pin 3 to insert into the limiting hole 204 to complete the secondary locking, and audio can be collected. When assembling the signal transmission module 5, insert the combination ring 501 into the combination slot 104, rotate the adjustment knob 6, and through gear transmission, the swing block 702 pushes the limiting pin 8 into the limiting groove 502. At the same time, the limiting slide rod 601 is magnetically fixed. When disassembling, rotate the knob in the opposite direction, and the limiting pin 8 retracts under the action of the spring, so the module can be pulled out. In daily use, the knob can be finely adjusted to ensure stable connection. When the functional module 2 malfunctions, disconnect the battery power supply, pull it out directly for repair, and reassemble according to the original steps after completion.

[0021] Example 2: A silicone sealing ring is added to the opening of the connector 101 of the handheld main body 1. A ring boss is provided at the corresponding position on the bottom of the functional module 2. During assembly, the boss is pressed into the sealing ring to form a seal, which can prevent dust and a small amount of water splash, and avoid problems with the internal circuit. A water-swellable water-stop strip is installed on the inner wall of the combination groove 104 of the handheld main body 1. A pressure strip is provided on the outer side of the combination ring 501 of the signal transmission module 5. During assembly, the pressure strip squeezes the water-stop strip to block water vapor, which is suitable for use in humid outdoor environments.
