[0029] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0030] It should be noted that the descriptions involving "first", "second", etc. in the present utility model are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present utility model.

[0031] Refer to Figures 1-4 An embodiment of a clamping assembly of the present utility model shown, including a substrate 1, a connecting portion 4 is provided on the bottom side of the substrate 1, and the connecting portion 4 is used to connect a backup power supply. On one side of the top end of the substrate 1, there is a first member 12, and the first member 12 is fixedly connected to the substrate 1. The first member 12 can also be integrally formed with the substrate 1. On the other side of the top end of the substrate 1, there is a second member 2, and the second member 2 is configured to be able to approach or move away from the first member 12, and a space for accommodating the equipment is formed between the first member 12 and the second member 2. A locking member is also provided on the second member 2 to lock the position of the second member 2.

[0032] By setting the first component 12 and the movable second component 2, the first component 12 and the second component 2 are used to clamp the bottom ends of the handles of equipment commonly used in daily life, such as megaphones, metal detectors, batons, and breathalyzers, and a connecting part 4 is set to connect a backup power source. Thus, the backup power source can be conveniently loaded on the equipment itself, improving the usability and reducing the personnel load.

[0033] Both the first component 12 and the second component 2 include arc plates, and at least part of the inner side walls of the arc plates are provided with damping material layers. In this way, it is used to adapt to the shape of the equipment handle and form a relatively fitting clamp. The damping material layers 16 and 21 are used to increase the friction coefficient and ensure that the equipment will not fall off the clamping assembly.

[0034] A track 11 for accommodating the second component 2 is provided on the base plate 1. The second component 2 is configured to be able to approach or move away from the first component 12 along the direction of the track 11. The track 11 thus plays a guiding role. An elastic member (not shown in the figure), specifically a spring, is provided in the track 11. One end of the elastic member is fixedly connected to the second component 2, and the other end is fixedly connected to the end of the track 11. The elastic member is used to compensate for the distance between the first component 12 and the second component 2, making the clamping process tighter.

[0035] Specifically, the locking member includes a cylindrical pin 31 with the first end fixedly connected to the second component 2. The second end of the cylindrical pin 31 passes through the first component 12, and at least part of the second end is eccentrically circularly connected to a third component 3. When the third component 3 rotates, the eccentric circular structure 32 of the third component 3 also rotates. According to the change in the diameter of the eccentric circle, the distance between the top end of the cylindrical pin 31 and the outside of the first component 12 changes under the drive of the eccentric circular structure 32. When the third component 3 is rotated to the locked position, that is, when the center of the eccentric circular structure 32 of the third component 3 is far from the outside of the first component 12, at this time, the cylindrical pin 31 drives the second component 2 to move towards the first component 12 under the drive of the third component 3, so that the first component 12 and the second component 2 are kept clamped.

[0036] A chute 14 is further provided on the track 11 along the direction of the track 11. A pin 22 protruding from the bottom of the second component 2 is provided on the corresponding second component 2, and the bottom of the pin 22 extends into the chute 14. The guiding effect is achieved through the cooperation of the pin 22 and the chute 14 to ensure the moving direction of the second component 2.

[0037] In some preferred embodiments, retaining bars 15 for preventing the second component 2 from slipping out of the track 11 are provided above both sides of the track 11.

[0038] In some preferred embodiments, the connecting portion 4 is a threaded interface.

[0039] The present utility model further provides a device, comprising: the clamping assembly as described above and a power supply module 5.

[0040] The power supply module 5 includes: a hollow cylinder body and a battery sleeved in the cylinder body. A threaded connecting portion 4 for detachably connecting to the connecting portion 4 is provided at the top of the cylinder body.

[0041] The power supply module further includes an output board and a control board. The output board is disposed on top of the battery and electrically connected to the battery. At least a power output unit and a voltage detection unit are provided on the output board. The voltage detection unit is used to detect the working voltage signal of the externally connected module. Specifically, the output board can also perform reverse input to charge the battery through the output board.

[0042] The control board is electrically connected to the output board and the battery respectively, and is used to receive the working voltage signal and control the voltage output by the battery. Specifically, in order to supply power to different external functional modules, the voltage detection unit detects the working voltage signal of the externally connected module and sends it to the control board. After receiving the signal, the control board performs parsing and processing, and adjusts the voltage output by the battery to be in line with the voltage of the external functional module.

[0043] Furthermore, an end cap 51 is detachably connected to the top of the cylinder body. A threaded counterbore is provided at the top of the end cap 51, and the threaded counterbore is detachably connected to the connecting portion 4.

[0044] The above are only the preferred embodiments of the present utility model. It should be pointed out that: for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
