Description
DESCRIPTION OF THE DRAWINGS
[0015]
[0016] The reference characters are as follows:
[0017] 1, a ring; 2, an upper cover, 3, a motor, 4, a linkage shaft; 5, a fixing block; 6, a fixing block; 7, a telescopic ring; and 8, a lower cover.
DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
[0018] The present disclosure is further described below with reference to the drawings.
[0019] Referring to
[0020] In the above structures, the motor 3 drives the linkage shaft 4 to rotate, and then drives the telescopic ring 7, the guiding post 6, the fixing block 5 and a ring 1 to move telescopically. The principle of the telescopic structure is that the guiding post 6 cooperates with a guiding groove defined on the linkage shaft 4 to move telescopically, and then a direction of the telescopic ring 7 is fixed by slots defined on the upper and lower plastic cover 8, so as to function as a telescopic structure.
[0021] In order to further improve the function of the telescopic structure, the upper cover 2 and the lower cover 8 are connected by screws, the upper cover 2 is made of plastic and the lower cover 8 is made of plastic. The motor 3 is embedded between the upper cover 2 and lower cover 8. The motor 3 is coaxially connected to the linkage shaft 4, and the linkage shaft 4 is made of plastic. The linkage shaft 4 is coupled with the telescopic ring 7, and the telescopic ring 7 is made of plastic. The guiding post 6 is coupled with the telescopic ring 7, and the guiding post 6 is made of a zinc alloy. The fixing block 5 is coupled with the guiding post 6, the fixing block 5 is coupled with the upper cover 2, and the fixing block 5 is made of plastic. The ring 1 is sleeved on the upper cover 2 and the lower cover 8, and the ring 1 is made of plastic.
[0022] The basic principles, main features and advantages of the invention have been shown and described above. It should be understood by those of ordinary skill in the art that the present invention should not be limited by embodiments described above. What described in the embodiments and specification is to illustrate the principles of the invention, and there are various changes and modifications to these embodiments without departing from the spirit or scope of the invention, which should fall in the scope of the invention claimed.
