a bed board movably disposed on the image receiving board 26. The bed board can be provided with a therapeutic body. The bed board can also be connected with the image receiving board 26 through a connecting piece. When the bed board rotates alone, the image receiving board 26 can be detached or moved out, so that the moving support board 1 can move relative to the moving support frame 2, and the flexible operation of the bed board can also be realized. The connector may be a bolt or a screw, and any connector may be used as long as it can connect the image receiving plate 26 and the bed plate, and is not limited herein.
The embodiment of the invention also provides the image equipment, which comprises the image equipment telescopic device.
Since the image device expansion device of the embodiment of the present invention is applied to an image device, an embodiment of the present invention further provides an image device, wherein the implementation embodiments of the image device expansion device are all applicable to the embodiment of the image device, and the same technical effect can be achieved.
While the foregoing is directed to the preferred embodiment of the present invention, it will be appreciated by those skilled in the art that various changes and modifications may be made therein without departing from the principles of the invention as set forth in the appended claims.
