[0015] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0016] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] Please see Figure 1-4 A metal bracket for easy angle adjustment includes a device base 1. The top of the device base 1 has two symmetrical adjustment discs 3 protruding from each other. A support arm 8 is rotatably mounted between the two adjustment discs 3. One of the adjustment discs 3 has an arc-shaped guide groove 4. The support arm 8 has a connecting post 14 protruding from the arc-shaped guide groove 4 and extending outward. A connector 7 is slidably arranged on the connecting post 14. A stop block 10 is protruding on the connector 7. The side of the stop block 10 near the adjustment disc 3 has a plurality of spaced limiting teeth. The adjustment disc 3 has a plurality of tooth grooves 6 spaced along the circumferential direction that are adapted to the limiting teeth. The adjustment disc 3 has a scale groove 5 along the circumferential direction.

[0019] When the angle of the support arm 8 needs to be adjusted, first rotate the hand-tightening bolt 11 to disengage it from the threaded hole 18 on the inner wall of the bottom of the sliding cavity 15. At this time, the connecting piece 7 can slide on the connecting post 14, and the limiting teeth on the abutment block 10 separate from the toothed groove 6 on the adjusting plate 3. Next, rotate the support arm 8, which rotates around the pivot in the rotating groove 12, while the connecting post 14 slides in the arc-shaped guide groove 4. During the rotation, the user can precisely control the adjustment angle of the support arm 8 according to the scale groove 5 on the adjusting plate 3. After adjusting to the desired angle, rotate the hand-tightening bolt 11 in the opposite direction to screw it into the threaded hole 18. The connecting piece 7 slides towards the adjusting plate 3 under the drive of the sliding block 16 and the connecting rod 17, and the limiting teeth on the abutment block 10 engage with the toothed groove 6 on the adjusting plate 3, thereby stably fixing the support arm 8 at that angle.

[0020] Specifically, in this embodiment, a connecting plate 9 is provided at the end of the support arm 8 away from the device base 1, and four through holes 13 arranged in a matrix are provided on the connecting plate 9.

[0021] The matrix-distributed through holes 13 provide more stable and balanced connection points, making the equipment more secure after installation. Different types of equipment may require different installation methods. Through these through holes 13, common connectors such as bolts and screws can be used to firmly fix the equipment to the connecting plate 9, enhancing the versatility and practicality of the metal bracket and enabling it to support a variety of different equipment.

[0022] Specifically, in this embodiment, the device base 1 has four mounting holes 2 arranged in a matrix for threading bolts.

[0023] The matrix distribution design allows the device base 1 to be subjected to force more evenly during installation, ensuring the stability of the bracket installation. By inserting bolts, the device base 1 can be firmly connected to the ground, wall or other supporting surface, providing a stable foundation for the entire metal bracket and preventing shaking or displacement due to external forces during use.

[0024] Specifically, in this embodiment, a sliding cavity 15 is provided on the connecting column 14, and a sliding block 16 is slidably arranged in the sliding cavity 15. The sliding block 16 is connected to the connecting member 7 through the connecting rod 17.

[0025] The sliding cavity 15 provides stable guidance and support for the sliding of the connector 7 on the connecting post 14. The sliding cavity 15 restricts the movement trajectory of the sliding block 16, ensuring that the connector 7 can only slide in a specific direction, thus guaranteeing the accuracy and stability of the abutment block 10 during movement. The connecting rod 17 connects the sliding block 16 and the connector 7, transmitting the movement of the sliding block 16 to the connector 7, thereby achieving relative position adjustment between the abutment block 10 and the adjusting disc 3, providing a reliable mechanical structure for locking and unlocking the angle.

[0026] Specifically, in this embodiment, the connector 7 is provided with a hand-tightening bolt 11 that penetrates the sliding block 16, and the bottom inner wall of the sliding cavity 15 is provided with a threaded hole 18 that is compatible with the hand-tightening bolt 11.

[0027] The design of the hand-tightening bolt 11 allows for convenient manual operation without the need for other tools. By rotating the hand-tightening bolt 11, the sliding of the connecting piece 7 can be easily controlled through the engagement of the bolt and the threaded hole 18. When it is necessary to adjust the angle of the support arm 8, loosening the hand-tightening bolt 11 allows the connecting piece 7 to slide freely, causing the limiting teeth on the abutment block 10 to separate from the toothed groove 6 on the adjusting disc 3. After adjusting to the appropriate angle, tightening the hand-tightening bolt 11 causes the connecting piece 7 to slide, engaging the limiting teeth with the toothed groove 6, thereby locking the angle of the support arm 8. The operation is simple and convenient, improving efficiency.

[0028] Specifically, in this embodiment, a rotating groove 12 is formed between the two adjusting discs 3, allowing the support arm 8 to move. The support arm 8 is rotatably mounted in the rotating groove 12 via a rotating shaft.

[0029] The rotating groove 12 provides space for the rotation of the support arm 8, allowing the support arm 8 to rotate freely between the two adjusting discs 3 to achieve angle adjustment. It also limits the rotation of the support arm 8, ensuring that the support arm 8 can only rotate within a specified range, thus preventing the support arm 8 from shifting or wobbling during rotation and improving the accuracy and stability of angle adjustment.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
