[0023] The support plate 13 is disposed on the top of the receiving cavity of the housing 10 , wherein the support plate 13 is provided with a slide groove 131 , and the bull's eye assembly 11 is slidably disposed in the slide groove 131 . That is, the bull's eye assembly 11 can slide along the slide groove 131 .

[0024] One end of the rotating rod 14 is rotatably set on the support plate 13, and the other end of the rotating rod 14 corresponds to the slide groove 131, wherein the other end of the rotating rod 14 is connected to the bull's eye assembly 11, so that the bull's eye assembly 11 can be driven to slide in the slide groove 131 by the rotating rod 14, so that the bull's eye assembly 11 can be adjusted. The bull's eye assembly 11 can be driven to slide in the shell 10 by the rotating rod 14 to flexibly adjust the position of the bull's eye assembly 1 so that the bull's eye assembly 11 will not be often exposed outside the optometry hole 101, which has high flexibility and is conducive to various maintenance operations (such as cleaning and repair, etc.).

[0025] In this embodiment, the driving motor 12 is disposed on the supporting plate 13 , wherein the rotating shaft of the driving motor 12 is connected to the rotating rod 14 , so that the driving motor 12 drives the rotating rod 14 to rotate, thereby driving the bull's eye assembly 11 to slide in the sliding groove 131 .

[0026] Preferably, the slide slot 131 is in an arc shape, wherein one end of the slide slot 131 is disposed on the first side of the support plate 13 and is located above the optometry hole 101. It should be understood that when the rotating rod 14 drives the bull's eye assembly 11 to slide to one end of the slide slot 131, the bull's eye assembly 11 is located at the optometry hole 101, which is convenient for detecting the human eye. In addition, when the rotating rod 14 drives the bull's eye assembly 11 to slide to the other end of the slide slot 131, the bull's eye assembly 11 is contained in the cavity (no longer located at the optometry hole 101), which is convenient for various maintenance operations (such as cleaning and repair, etc.).

[0027] Preferably, the support plate 13 is rectangular, wherein the other end of the slide slot 131 is located at the second side of the support plate 13 , and the first side is adjacent to the second side.

[0030] Furthermore, the drive motor 12 is arranged in the mounting block 132, and the drive assembly includes a first synchronous wheel 121, a second synchronous wheel 122 and a synchronous belt, wherein the first synchronous wheel 121 is arranged at the bottom end of the rotating shaft 141 away from the rotating rod 14, and the second synchronous wheel 122 is arranged in the rotating shaft of the drive motor 12, and the synchronous belt is arranged around the first synchronous wheel 121 and the second synchronous wheel 122, so that when the drive motor 12 drives the second synchronous wheel 122 to rotate, the second synchronous wheel 122 drives the first synchronous wheel 121 to rotate through the synchronous belt, thereby driving the rotating shaft 141 to rotate.

[0031] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.
