[0002] During the process of riding a bicycle, an electric vehicle, or a motorcycle, a mobile phone bracket can be installed with the help of an expansion clip, so as to facilitate the rider to view the navigation and answer calls. In addition, the expansion clip can also be used to fix a sports camera to record wonderful moments; or install a lamp to improve the safety of night riding.

[0003] Most of the existing expansion clips on the market can only fix one accessory, and have a single function. They cannot adjust the direction and expand downward, cannot be docked for use, and the clamping range and angle are limited, so the applicable range is small. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is that the existing expansion clips on the market have a single function, cannot adjust the direction and expand downward, cannot be docked for use, and the clamping range and angle are limited, so the applicable range is small.

[0005] To solve the above technical problems, the technical solution provided by the utility model is a multi-purpose expansion clip, which includes a plurality of clamping brackets. The clamping brackets are composed of a combined bracket with two symmetrically arranged bow-shaped structures. A clamping groove is arranged inside the combined bracket. The inside of the clamping groove is composed of a plurality of semi-circular notches with different diameters. The other end of the combined bracket is provided with a first expansion groove. The first expansion groove is rotationally connected with a second expansion groove through a connecting bolt. A corresponding positioning groove is arranged at the connection of the combined bracket far away from the clamping groove and the first expansion groove and the second expansion groove.

[0006] Preferably, the two ends of the two combined brackets are connected and matched through a first connecting bolt, which is used to connect and extend the two ends of the two combined brackets.

[0007] Preferably, the middle of the combined bracket is threadedly connected with the bottom of the first expansion groove or the second expansion groove through a second connecting bolt, which is used to connect the combined bracket with the first expansion groove or the second expansion groove.

[0008] Preferably, a plurality of circular plug-in plates are staggered at the top of the first expansion groove and the second expansion groove. Among them, the plurality of plug-in plates of the first expansion groove are located on both sides and in the middle, and the plurality of plug-in plates of the second expansion groove are staggered with the first expansion groove, which is used for the connection between the first expansion groove and the second expansion groove.

[0009] Preferably, a fastening bolt is provided at the top of the connecting bolt. The fastening bolt passes through the first expansion slot and the second expansion slot. A corresponding threaded sleeve is provided at one end of the first expansion slot away from the connecting bolt. One end of the fastening bolt is in threaded fit with the threaded sleeve on one side of the first expansion slot. The other end of the connecting bolt is a rotating rod with a long handle.

[0010] Preferably, the positioning slot is of a square structure as a whole, and positioning blocks matching the shape of the positioning slot are provided at the bottoms of the first expansion slot and the second expansion slot.

[0011] The advantages of the present utility model compared with the prior art are as follows:

[0012] This expansion clip adopts the design of separating the expansion slots, which can adjust the clamping direction. Moreover, the lower half of this expansion clip still retains the positioning slot, so that on the basis of the original bracket, upward or downward expansion space can be obtained, which is convenient for installing multiple devices and accessories. And in combination with the expansion slots, two accessories can be used in combination. BRIEF DESCRIPTION OF THE DRAWINGS

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0023] Embodiment 1:

[0024] As shown in the Figure 1-2 specification appendix, a multi-purpose expansion clip includes a plurality of clamping brackets 1. The clamping brackets 1 are composed of two symmetrically arranged combined brackets 2 in the shape of an arch. The two ends of the two combined brackets 2 are connected in cooperation through a first connecting bolt. A clamping groove 3 is arranged inside the combined bracket 2, and the inside of the clamping groove 3 is composed of a plurality of semi-circular notches with different diameters.

[0025] In the present utility model, a first expansion slot 4 is arranged at the other end of the combined bracket 2. The first expansion slot 4 is rotationally connected with a second expansion slot 6 through a connecting bolt 5. The middle of the combined bracket 2 is threadedly connected with the bottom of the first expansion slot 4 or the second expansion slot 6 through a second connecting bolt. A plurality of circular plug-in plates 8 are arranged alternately at the tops of the first expansion slot 4 and the second expansion slot 6. Among them, a plurality of plug-in plates 8 of the first expansion slot 4 are located on both sides and in the middle, and a plurality of plug-in plates 8 of the second expansion slot 6 are arranged alternately with the first expansion slot 4. A fastening bolt 9 is arranged at the top of the connecting bolt 5. The fastening bolt 9 passes through the first expansion slot 4 and the second expansion slot 6. A corresponding threaded sleeve 10 is arranged at one end of the first expansion slot 4 away from the connecting bolt 5. One end of the fastening bolt 9 is in threaded connection with the threaded sleeve 10 on one side of the first expansion slot 4 through a thread. The other end of the connecting bolt 5 is a rotating rod with a long handle.
