Abstract

The invention discloses a novel head fixing device for ophthalmologic examination and belongs to the technical field of fixing devices. The novel head fixing device comprises a supporting base, wherein a second electric telescopic rod is arranged at the middle part of the upper surface of the supporting base, a fixing mechanism is arranged at the top end of the second electric telescopic rod and comprises a driving motor, a limiting base is arranged at an output end of the driving motor, a fixing base is arranged above the limiting base, a limiting slide plate is arranged at the middle part ofthe lower surface of the fixing base, a limiting sliding groove corresponding to the limiting slide plate is formed in the limiting base, third limiting plates corresponding to the limiting base arefurther arranged at the two ends of the lower surface of the fixing base, and a second cushion pad is arranged at the middle part of the upper surface of the fixing base. The novel head fixing deviceis simple in structure and convenient in use, has a good fixing function and can exert a good fixing effect on the head of a sufferer, and the user experience of the fixing device by a user is improved.

Description

technical field [0001] The invention belongs to the technical field of fixing devices, and in particular relates to a novel head fixing device for ophthalmic examination. Background technique [0002] Chinese patent (publication number CN208598365U) discloses a head fixing device for ophthalmic examination, including a bottom plate, etc.; wheels are installed at the four corners of the bottom of the bottom plate by bolts, and a lifting device is arranged in the middle of the bottom of the bottom plate. There are fixing devices on the lifting parts. [0003] The advantage of this utility model is that the height of the fixing device is adjusted by the lifting device, and the patient's head is fixed by the fixing device, thereby achieving the effect of conveniently checking the patient's eyes without affecting the inspection. [0004] However, due to the relatively simple structure of the fixing device, the patient's head can still move after being fixed, so that the fixing e...
