[0023] Two clips 6 are symmetrically arranged on the inner wall of the edging portion 5, and the clips 6 are provided with clip holes 601 through them. An inner groove 402 is opened on the outer wall of the docking portion 4 at a position corresponding to the clips 6, and a clip block 403 is integrally formed on the inner wall of the inner groove 402. The two clip blocks 403 respectively correspond to the two clips 6 and are snap-connected. The edging portion 5 has a movable gap 502 at the position corresponding to the two sides of the clips 6, so that the clips 6 can be deformed when subjected to external force and return to their original state when the external force disappears.

[0024] When assembling the movement, the movement structure is aligned and assembled in the installation groove 102, and the second shell 2 is aligned and assembled on the first shell 1. The inner wall of the edging portion 5 covers the outer wall of the docking portion 4, and an inclined surface is formed between the fastener 6 and the corresponding block 403. Under the guidance of the inclined surface, the fastener 6 is squeezed and deformed by the block 403 so that the fastener 6 can be inserted into the corresponding inner groove 402 until the block 403 corresponds to the position of the hole 601. Then, the fastener 6 recovers its deformation, and the block 403 enters the hole 601, thereby realizing a snap-on connection between the block 403 and the fastener 6 to maintain the connection state between the first shell 1 and the second shell 2. At this time, the fastener 6 and the corresponding inner groove 402 are adapted to each other. The edging portion 5 and the docking portion 4 are connected by a snap-on connection through a clamping block 403 and a snap-on piece 6, so that the first shell 1 and the second shell 2 are easy to assemble and disassemble and the connection is firm. The structure of the movement is stable and reliable. The edging portion 5 wraps the outer wall of the docking portion 4 to protect the outer shell body and improve the anti-fall performance of the movement.

[0025] The first shell 1 is provided with a baffle portion 7 at a position corresponding to the open end of the U-shaped structure, and the baffle portion 7 divides the inner cavity of the first shell 1 into a battery slot 101 and a mounting slot 102. The inner wall of the baffle portion 7 is provided with a first positioning slot 701, and the second shell 2 is provided with a first positioning portion 201 inserted into the first positioning slot 701. The inner wall of the docking portion 4 is provided with a second positioning slot 401, and the inner wall of the edging portion 5 is provided with a second positioning portion 501 inserted into the second positioning slot 401, so that the outer wall of the docking portion 4 and the edging portion 5 are aligned. The inner wall of the mounting groove 102 is matched with the concave and convex parts to guide the first shell 1 and the second shell 2 to be assembled together; preferably, two first connecting columns 8 are arranged on the inner wall of the mounting groove 102, and two second connecting columns 9 are arranged on the inner cavity wall of the second shell 2, the first connecting columns 8 correspond to the corresponding second connecting columns 9, and the opposite ends of the first connecting column 8 and the second connecting column 9 are respectively provided with a socket 801 and a plug column 901, and the plug column 901 is plugged into the socket 801, thereby improving the connection reliability between the first shell 1 and the second shell 2.

[0026] The mounting groove 102 cooperates with the inner cavity of the second shell 2 to form an installation cavity for the movement device 3 to be installed. The movement device 3 includes a gear transmission group 31 and a movement shaft 32. The gear transmission group 31 is installed in the installation cavity of the shell body. The first shell 1 is penetrated with a through hole 103. The movement shaft 32 extends to the outside of the first shell 1 through the through hole 103. The gear transmission group 31 is composed of a number of gears that mesh with each other. The gear shafts of each gear are rotatably connected in the installation cavity. Preferably, the gear shafts of the gears are made of metal. The battery slot 101 is used for battery installation. The gear transmission group 31 is connected to the rotating shaft of the rotating motor. The battery provides power to the rotating motor. The rotating motor drives the movement shaft 32 to rotate under the transmission of the gear transmission group 31. The edging portion 5 wraps the outer wall of the docking portion 4 to block the seam of the shell body to prevent sound from leaking through the gap, which plays a certain noise reduction role. Preferably, a sound insulation pad can also be installed in the installation cavity to further improve the noise reduction performance of the movement.

[0027] Of course, the above are only typical examples of the present invention. In addition, the present invention may have many other specific implementations. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
