The following is a more detailed description of the specific implementation of this utility model in conjunction with specific embodiments:

[0044] like Figures 1 to 3 As shown, the embodiment of the present invention provides a microphone wireless transmitter fixing device for fixing the wireless transmitter 4, so that the wireless transmitter 4 can realize the quick release function, improve the stability of the wireless transmitter 4 when fixed, and reduce the difficulty of disassembly and assembly of the wireless transmitter 4, thereby improving the disassembly and assembly efficiency; the following is an explanation through specific embodiments:

[0045] Microphone Wireless Transmitter Mounting Kit Includes:

[0046] The extension rod bracket 1 and the quick release assembly 2 provided on the extension rod bracket 1; the extension rod bracket 1 is used to connect with the extension rod, the quick release assembly 2 includes a quick release bracket 21, a quick release pressure block 22 provided on the quick release bracket 21, and a quick release wrench 23, the quick release bracket 21 and the quick release pressure block 22 are provided on the extension rod bracket 1, a shaft 24 is provided between the quick release bracket 21 and the quick release pressure block 22, the quick release wrench 23 is connected to the shaft 24 and can rotate around the shaft 24, and a quick release wrench 23 is formed between the quick release bracket 21 A quick-release slot 25 is provided for accommodating the connector 41 of the wireless transmitter 4. The quick-release pressure block 22 is provided with an elastic structure 221. When the quick-release wrench 23 is rotated to a position closing the quick-release slot 25, the elastic structure 221 applies an elastic force to the quick-release wrench 23, so that the quick-release wrench 23 and the quick-release bracket 21 jointly clamp the connector 41. When the quick-release wrench 23 is rotated to a position opening the quick-release slot 25, the elastic structure 221 reduces the elastic force on the quick-release wrench 23, so that the quick-release wrench 23 and the quick-release bracket 21 release the connector 41.

[0047] Here, it can be understood that the extension rod bracket 1 refers to a bracket used to connect with the extension rod. The extension rod bracket 1 serves as a connecting component between the wireless transmitter 4 and the extension rod to achieve the connection between the wireless transmitter and the extension rod;

[0048] The quick-release assembly 2 is a component used to achieve a detachable connection with the wireless transmitter 4; the quick-release assembly 2 includes a quick-release bracket 21, a quick-release pressure block 22, and a quick-release wrench 23;

[0049] The quick-release bracket 21 is a bracket connected to the extension rod bracket, and is used to support the quick-release pressure block 22 and the quick-release wrench 23;

[0050] The quick release pressure block 22 is a pressure block used to apply force to the quick release wrench 23. A shaft 24 is provided between the quick release pressure block 22 and the quick release bracket 21. An elastic structure 221 is provided on the quick release pressure block 22. The quick release wrench 23 is a wrench for the operator to operate. A quick release slot 25 is formed between the quick release pressure block 22 and the quick release bracket 21. The shape and size of the quick release slot 25 match the shape and size of the connector 41 of the wireless transmitter 4, so that the connector 41 can be just inserted into the quick release slot. The quick-release slot 25 is in the quick-release slot 25 and has a clearance fit with the quick-release slot 25; the operator can drive the quick-release wrench 23 to rotate around the shaft 24, so that the quick-release wrench 23 rotates around the shaft 24 to open or close the quick-release slot 25. When the quick-release slot 25 is closed, the quick-release wrench 23 locks the connector 41, thereby fixing the connection between the wireless transmitter 4 and the quick-release bracket 21; and when the quick-release slot 25 is opened, the quick-release wrench 23 loosens the connector 41, so that the wireless transmitter 4 and the quick-release bracket 21 can be separated.

[0051] like Figure 4 and Figure 5 As shown, the specific working principle of the microphone wireless transmitter fixing device provided in this embodiment is as follows:

[0052] Insert the connector 41 of the wireless transmitter 4 into the quick-release slot 25, and the operator drives the quick-release wrench 23 to rotate around the shaft 24 to the position of closing the quick-release slot 25. At this time, the elastic structure 221 of the quick-release pressure block 22 exerts elastic force on the quick-release wrench 23, so that the quick-release wrench 23 maintains the state of closing the quick-release slot 25 and clamps the connector 41 together with the quick-release bracket 21, thus achieving a fixed connection between the wireless transmitter 4 and the microphone wireless transmitter fixing device;

[0053] The operator drives the quick-release wrench 23 to rotate around the shaft 24 to the position of opening the quick-release slot 25. At this time, the elastic structure 221 of the quick-release pressure block 22 reduces the elastic force applied to the quick-release wrench 23, so that the quick-release wrench 23 and the quick-release bracket 21 loosen the joint 41, thereby releasing the fixed connection between the wireless transmitter 4 and the microphone wireless transmitter fixing device.

[0054] By adopting the above technical solution, the operator can connect and disconnect the wireless transmitter 4 and the microphone wireless transmitter fixing device with one hand, thereby improving the speed and efficiency of disassembling and assembling the wireless transmitter 4, and at the same time, improving the stability of the wireless transmitter 4 when it is fixed.

[0055] like Figure 6 and Figure 7 As shown, in one embodiment, the quick-release pressure block 22 includes a pressure block body 222 and an elastic structure 221 provided on the pressure block body 222. The pressure block body 222 is provided on the quick-release bracket 21. The elastic structure 221 includes a connecting section 2211 and an elastic section 2212. The connecting section 2211 is connected to the pressure block body 222. The elastic section 2212 is connected to the connecting section 2211. The elastic section 2212 can move elastically relative to the connecting section 2211.

[0056] Here, it can be understood that the elastic structure 221 is elastic and can exert elastic force on the quick-release wrench 23; specifically, the elastic structure 221 includes a connecting section 2211 and an elastic section 2212, wherein the connecting section 2211 is used to connect with the pressure block body 222, the elastic section 2212 is elastic, and the elastic section 2212 is connected to the connecting section 2211. When the elastic section 2212 is deformed, it can provide elastic force, so that the quick-release wrench 23 can maintain the state of closing or opening the quick-release slot 25.

[0057] By adopting the above technical solution, the elastic structure 221 and the quick release wrench 23 are elastically abutted, so that the elastic structure 221 can exert elastic force on the quick release wrench 23, causing the quick release wrench 23 to close or open the quick release slot 25.

[0058] In one embodiment, the quick-release pressure block 22 further includes a limiting structure 223 provided on the pressure block body 222 , a limiting gap is reserved between the limiting structure 223 and the elastic structure 221 , and the limiting structure 223 is arranged close to the elastic section 2212 , and the limiting structure 223 is used to limit the movement of the elastic section 2212 .

[0059] Here, it can be understood that the limiting structure 223 is used to limit the elastic structure 221 to prevent the elastic structure 221 from being too elastic and causing a failure in the cooperation with the quick release wrench 23 .

[0060] By adopting the above technical solution, the reliability of the elastic structure 221 is improved.

[0061] In one embodiment, the quick-release wrench 23 includes a wrench body 231 and a pressing structure 232 provided on the wrench body 231 . The wrench body 231 is connected to the shaft 24 . The pressing structure 232 is provided on the wrench body 231 and is used to press the connector 41 .

[0062] Here, it can be understood that the wrench body 231 is used for the operator to turn, and the pressing structure 232 is used to press the joint 41. The operator turns the wrench body 231 to drive the pressing structure 232 to rotate around the shaft 24. When the wrench body 231 is rotated to the position of closing the quick-release slot 25, the pressing structure 232 presses on the joint 41, and the pressing structure 232 and the quick-release bracket 21 jointly clamp the joint 41.

[0063] Optionally, the pressing structure 232 is located on a side of the wrench body 231 close to the quick-release slot 25 , which facilitates the pressing structure 232 to press against the connector 41 .

[0064] Furthermore, the surface of the pressing structure 232 close to the quick-release slot 25 is an arc-shaped surface, and the shape of the arc-shaped surface adapts to the surface of the joint 41, so that the contact area of ​​the pressing structure 232 is larger when pressing against the joint 41, thereby increasing the friction force when the quick-release wrench 23 clamps the joint 41, and further improving the stability of the joint 41 when fixed.

[0065] By adopting the above technical solution, the stability of the joint 41 during fixation is further improved.

[0066] In one embodiment, the elastic section 2212 is provided with an elastic groove 2213, and the wrench body 231 is provided with an eccentric structure 233 accommodated in the elastic groove 2213. The eccentric structure 233 has a convex portion 2331 and a flat portion 2332. The distance between the convex portion 2331 and the shaft body 24 is greater than the distance between the flat portion 2332 and the shaft body 24. When the quick-release wrench 23 is rotated to close the quick-release slot 25, the convex portion 2331 is located in the elastic groove 2213. The elastic section 2212 increases the elastic force applied to the convex portion 2331, causing the pressing structure 232 to press against the joint 41. When the quick-release wrench 23 is rotated to open the quick-release slot 25, the flat portion 2332 is located in the elastic groove 2213. The elastic section 2212 reduces the elastic force applied to the flat portion 2332, causing the pressing structure 232 to release the joint 41.

[0067] Here, it can be understood that the elastic section 2212 is provided with an elastic groove 2213, and the elastic groove 2213 is used to accommodate the eccentric structure 233 on the wrench body 231. The eccentric structure 233 has a convex portion 2331 and a flat portion 2332. The eccentric structure 233 rotates around the shaft 24 along with the wrench body 231;

[0068] When the quick-release wrench 23 is rotated to the position closing the quick-release slot 25, the protrusion 2331 rotates to be accommodated in the elastic groove 2213. Due to the large distance between the protrusion 2331 and the shaft 24, the protrusion 2331 presses the elastic section 2212. The elastic section 2212 exerts an elastic force on the protrusion 2331, fixing the protrusion 2331 relative to the elastic section 2212. At the same time, the elastic force of the elastic section 2212 maintains the quick-release wrench 23 in the position closing the quick-release slot 25, so that the quick-release wrench 23 and the quick-release bracket 21 jointly clamp the connector 41.

[0069] When the quick-release wrench 23 is rotated to the position where the quick-release slot 25 is opened, the flat portion 2332 is rotated to be accommodated in the elastic slot 2213. Since the distance between the flat portion 2332 and the shaft 24 is small, the flat portion 2332 no longer presses the elastic section 2212. The elastic force exerted by the elastic section 2212 on the flat portion 2332 is small, and the quick-release wrench 23 and the quick-release bracket 21 no longer clamp the connector 41. In other words, the quick-release wrench 23 and the quick-release bracket 21 release the connector 41.

[0070] By adopting the above technical solution, the cooperation between the quick-release wrench 23 and the elastic structure 221 is simple and reliable.

[0071] Please refer again Figure 3 In one embodiment, the extension rod bracket 1 includes a first frame 11 and a second frame 12 connected to the first frame 11 , the first frame 11 is provided with a quick-release assembly 2 , and the second frame 12 is used to set a power supply device 3 .

[0072] Here, it can be understood that the extension rod bracket 1 is used to fix the quick-release assembly 2 and the power supply device 3, and the power supply device 3 is used to provide power to the wireless transmitter 4, wherein the power supply device 3 can be electrically connected to the wireless transmitter 4 through a cable, and the first battery 33 can also be removed from the power supply device 3 and then installed on the wireless transmitter 4, thereby increasing the battery life of the wireless transmitter 4.

[0077] In one embodiment, the power supply device 3 includes a power socket 32 ​​and a first battery 33 detachably mounted on the power socket 32 ​​. The power socket 32 ​​is mounted on the second frame 12 .

[0078] Here, it can be understood that the first battery 33 can be removed from the power socket 32 ​​and installed in the wireless transmitter 4 to replace the power supply.

[0079] By adopting the above technical solution, the endurance of the wireless transmitter 4 is improved.

[0080] In one embodiment, the power base 32 is further provided with an unlock button 31, which is in transmission connection with an unlocking structure on the power base 32, such that the unlock button 31 can drive the unlocking structure to unlock or lock the first battery 33. The operator can unlock the power base 32 and the first battery 33 by pressing the unlock button 31.
