In addition, there are many other businesses For products in various fields (such as: TVs, projectors, cameras, etc.), special program APPs are designed to allow handheld electronic devices to interact and manage them, thereby expanding infinite application possibilities.

However, as the functions of the handheld electronic devices become more and more abundant, people's dependence on the handheld electronic devices is also increasing. That is to say, you will be at a loss because of the loss of convenient tools. Therefore, how to improve the grip of the handheld electronic device, or how to make the handheld electronic device self-position on a plane when the user is inconvenient to hold it, has become a demand. A huge potential business opportunity is formed in the market.

At present, there are many accessories for protecting handheld electronic devices on the market, such as: protective cases, fixing frames, anti-scratch films, etc., but their functions have their limitations, as shown in Figure 1A, which is currently A "fixed frame" product, the fixed frame product includes a base A and a positioning seat B, one end of the base A is provided with a suction cup A1, so as to be able to be adsorbed on a plane (such as: car glass, desktop, etc.), the middle section The part is a bendable flexible pipe A2, and the other end is provided with a screw part; the positioning seat B is for placing a hand-held electronic device C, and its back is provided with a screw hole corresponding to the screw part. To be assembled with the other end of the base A. Although this fixing frame can effectively fix the handheld electronic device C on a plane, the positioning seat B in the fixing frame is not only bulky, but also needs to re-adsorb the suction cup A1, the locking screw hole and the screw each time it is used. It is inconvenient to use, so it is difficult to meet the needs of all users.

Please refer to Fig. 1B, which is a fixing fitting D designed by some industry in recent years. The fixing fitting D includes an adhesive plate D1, a connecting block D2 and a buckle D3. A board D11 and a second board D12 are bonded to each other, the connecting block D2 can be vertically fixed on the adhesive board D1 through a plurality of pins D4, and a Through the groove D21; the positions adjacent to the two ends of the buckle D3 are respectively penetrated with a through hole D31, so that an assembly component D5 can pass through the through holes D31 and the through groove D21, and assemble the buckle D3 to the adhesive plate D1 superior.

Although the above-mentioned fixing part D can pass through the buckle D3 for the user's fingers to pass through, to improve the grip, and utilize the rotatable characteristics of the buckle D3, the user can use the buckle D3 as a bracket. , the inventor found that the fixing fitting D still has several deficiencies: first, the assembly method of the latch D4, the connecting block D2, and the assembly component D5 is too complicated, which is not conducive to the production cost; secondly, when the user uses the buckle D3 as a bracket At this time, the support force of the buckle D3 depends on the friction between the buckle D3 itself and the through groove D21, and it is difficult for the industry to precisely control the magnitude of the friction, so that the buckle D3 is easily damaged due to excessive friction. Difficult to turn, or easy to loosen due to too little friction.

In addition, once the fixing part D is installed on a handheld electronic device, since the overall configuration and thickness of the handheld electronic device will change, it will no longer be installed on a general fixing frame (as shown in Figure 1A As shown), it is extremely inconvenient for some users, that is, the fixing accessory D still has problems of "high production cost", "complicated assembly method", "poor positioning of the buckle" and "unable to match custom Therefore, how to design a brand-new accessory structure to solve the aforementioned four problems becomes an important problem that the present invention wants to solve urgently here.
