Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and particularly relates to an accommodation flipper bracket. Background Art

[0002] In the prior art, an accommodation flipper is used for eye function training to fully mobilize the potential of the eyes themselves, which can effectively improve the reading speed, visual clarity and eye use comfort. The accommodation flipper, also known as a flip card or butterfly card, is composed of two pairs of prisms with equal positive and negative degrees and a holding handle. When in use, an eye chart is placed in front of the trainer, and the accommodation flipper is placed between the trainer's eyes and the eye chart. By holding the handle and flipping the two pairs of positive and negative prisms on the accommodation flipper back and forth, and ensuring that the trainer's eyes can clearly read each time of flipping, the number of changes from positive diopter to negative diopter within a certain period of time is recorded. Holding the accommodation flipper and flipping it up for a long time will cause muscle soreness in the trainer's arm, and the trainer may move back and forth because of unclear vision, resulting in inaccurate distance or secretly move the accommodation flipper so that the lens is not in front of the eyes. Improper operation will lead to poor training effect. Summary of the Invention

Embodiment

[0024] As Figures 1 - 4Shown: A flip card holder, which has basically the same structure as the flip card holder described in Embodiment 1. The difference is that: in this embodiment, the vertical rod 2 includes an inner rod 21 and an outer rod 22. The outer rod 22 is sleeved inside the inner rod 21. A locking device is provided at the connection part of the inner rod 21 and the outer rod 22. This locking device can be fixed by a knob. The knob passes through the inner rod 21 and contacts the outer rod 22. By tightening the outer rod 22, the height of the outer rod 22 is fixed, which is convenient for the vertical rod 2 to be stored. The rack 11 is arranged on one side surface of the inner rod 21.

[0025] As a variation of Embodiment 1 and Embodiment 2, as Figure 8 shown, the flip card holder further includes a connecting bar 13. One end of the connecting bar 13 is connected to the base 1, and the other end is connected to the flat plate holder 14. The connecting bar is 40 cm long, which can ensure that the distance from the flip card holder to the vision chart is 40 cm. The flat plate holder 14 can adjust the height and angle, similar to an existing mobile phone holder, and is used to place the tablet computer 15, and the tablet computer 15 is used to display the vision chart.
