The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0019] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0020] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a compact circuit board assembly for a smart watch of the utility model comprises a smart watch circuit board 1, a locking ring 3 and a plurality of fixing blocks 2, wherein the fixing blocks 2 are in an annular structure and are evenly distributed on the outer ring of the smart watch circuit board 1, the inner side surface of the fixing ring is recessed to form a connecting groove 9 of an arc structure, the locking ring 3 is inserted into the plurality of connecting grooves 9 from top to bottom, the bottom surface of the locking ring 3 is arranged in contact with the top surface of the smart watch circuit board 1, a groove is provided on the bottom surface of the smart watch circuit board 1 opposite to the fixing block 2, a lifting plate 7 movably connected to the fixing block 2 and used to lift the smart watch circuit board 1 upwards is provided in the groove.

[0022] In this embodiment, a fixing groove 8 connected to the groove is vertically provided on the inner side surface of the fixing block 2, one end of the lifting plate 7 is bent upward to form a fixing part 4, the fixing part 4 is inserted into the fixing groove 8, a first rotating shaft is installed on the fixing part 4, and a concave first slot 10 is provided on both sides of the fixing groove 8 opposite to the first rotating shaft, a spring is provided inside the first slot 10, and the outermost circle of the spring is installed on the inner circle surface of the first slot 10, both ends of the first rotating shaft are inserted into the first slot 10, and are installed in the innermost circle of the spring, the torsion of the spring can drive the rotation of the first rotating shaft, and the fixing part and the lifting plate are lifted upward to lift the smart watch circuit board upward.

[0023] In this embodiment, a plurality of connection parts 6 are protruded from the bottom surface of the fixing block 2. When fixing, the connection parts under the fixing block can be fixed to the bottom of the smart watch housing, thereby increasing the firmness after installation.

[0024] In this embodiment, an outer ring surface of the locking ring 3 is provided with an external thread, and an inner side surface of the connecting groove 9 is provided with an internal thread. The locking ring 3 is meshed and connected with the internal thread on the connecting groove 9 via the external thread.

[0025] In this embodiment, a mounting groove is provided on the inner ring surface of the locking ring 3, and a pull rod 5 is provided in the mounting groove to drive the locking ring 3 to rotate.
