[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present utility model are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly. In the present utility model, unless otherwise clearly specified and limited, the terms "connection", "fixed", etc. should be understood in a broad sense. For example, "fixed" can be a fixed connection, a detachable connection, or an integral whole; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0024] In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0025] The angle-adjustable bracket in this embodiment is as follows: Figures 1 to 5 As shown, it includes a mounting base 1 and a positioning frame 2; the mounting base 1 is used for installation and fixation, and the mounting base 1 can be fixed by gluing or screwing; the positioning frame 2 is used to position fans, mobile phones and other objects, and a buckle 21 can be set on the positioning frame 2, and the fans, mobile phones and other objects are clamped by the buckle 21, or other structures (such as elastic clamping mechanisms) are set on the positioning frame 2 to clamp and position the fans, mobile phones and other objects.

[0026] In order to adapt to the angle adjustment of the positioning frame 2, the positioning frame 2 is rotatably installed on the mounting seat 1, and one of the mounting seat 1 and the positioning frame 2 is provided with a plurality of positioning grooves 3 spaced apart around the rotation axis of the positioning frame 2, and the other of the mounting seat 1 and the positioning frame 2 is provided with an elastic positioning member at a position corresponding to the positioning groove 3, and the elastic positioning member cooperates with the positioning groove 3 to circumferentially position the positioning frame 2 to prevent the positioning frame 2 from rotating relative to the mounting seat 1. When the angle of the positioning frame 2 needs to be adjusted, the positioning frame 2 is rotated forcefully to disengage the elastic positioning member from the current positioning groove 3, and when the positioning frame 2 is rotated to a suitable angle, the elastic positioning member cooperates with the positioning groove 3 at the corresponding position to position the positioning frame 2 again; the structure in this embodiment is reasonable, and the angle adjustment of the positioning frame 2 can be realized to better meet the needs of customers.

[0027] like Figure 3 and Figure 5 As shown, the elastic positioning member includes a positioning pin 4 and a spring 5 that provides elastic force for the positioning pin 4. Under the action of the spring 5, the positioning pin 4 cooperates with the positioning slot 3 and is rotated when the angle of the positioning frame 2 is adjusted. When the positioning pin 4 slides out of the positioning slot 3, the spring 5 is gradually compressed. When the positioning frame 2 is adjusted into place, the spring 5 releases the elastic force to enable the positioning pin 4 to engage with the positioning slot 3.

[0028] like Figure 4 and Figure 5 As shown, in order to facilitate the rotatable connection between the positioning frame 2 and the mounting seat 1, in this embodiment, a protruding mounting shaft 6 is provided on the mounting seat 1, and a sleeve hole 7 is provided on the positioning frame 2. The sleeve hole 7 is movably sleeved with the mounting shaft 6 so that the positioning frame 2 can rotate relative to the mounting seat 1, and a baffle 8 for blocking and limiting the positioning frame 2 is fixed on the outer side of the positioning frame 2 on the mounting shaft 6. The baffle 8 is used to block and limit the positioning frame 2, so that the sleeve hole 7 and the mounting shaft 6 can remain in cooperation, thereby preventing the positioning frame 2 from detaching from the mounting seat 1.

[0029] like Figure 3 As shown, in order to install the elastic positioning member, a mounting groove 9 is provided on the mounting shaft 6 , the elastic positioning member is arranged in the mounting groove 9 , and the positioning groove 3 is arranged on the inner wall of the sleeve hole 7 .

[0030] like Figure 3 As shown, the mounting groove 9 radially penetrates the mounting shaft 6, there are two positioning pins 4 and the two positioning pins 4 are respectively arranged at both ends of the mounting groove 9, and the spring 5 is arranged between the two positioning pins 4. The two positioning pins 4 cooperate with the positioning grooves 3 at two relative positions at the same time to position the positioning frame 2 more stably and reliably, and a spring 5 provides elastic force for the two positioning pins 4 at the same time, and the structure is simple and feasible.

[0031] In some embodiments, the baffle 8 is a circular baffle, which is clipped or screwed to the mounting shaft 6. The outside of the positioning frame 2 is provided with an embedding groove 10 for embedding the circular baffle. The circular baffle is embedded by setting the embedding groove 10, thereby keeping the surface of the positioning frame 2 flat and improving the appearance.

[0032] In order to make the adjustment of the angle of the positioning frame 2 relatively smooth, the positioning groove 3 is preferably set to a V-shaped groove, a trapezoidal groove or an arc groove; the end of the positioning pin 4 suitable for cooperating with the positioning groove 3 is preferably set to a wedge shape or a hemispherical shape, so that when the positioning frame 2 is rotated, the positioning pin 4 can slide out of the positioning groove 3 relatively easily, and after the positioning pin 4 is inserted into the positioning groove 3, it can reliably contact the bottom of the positioning groove 3, thereby effectively positioning the positioning frame 2.

[0033] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
