Abstract

The invention discloses a neck limiting device capable of preventing approaching during writing, and relates to the technical field of myopia prevention. The neck limiting device comprises: a main body; a stable bottom plate, which is positioned below the main body; and an adjusting mechanism, which is mounted at the bottom end of the main body, located above the stable bottom plate and used for adjusting the angle of the main body. By arranging the adjusting mechanism, the mechanism can set off a chin angle, and a rotary knob is rotated to drive a rotary shaft so as to enable a ratchet wheel and a threaded rod to rotate; at the moment, a movable plate is driven by rotation of the threaded rod to drive an extrusion rolling shaft to move, and meanwhile, the extrusion rolling shaft extrudes the bottom end of a main body through the rotary shaft, so the main body is turned over through hinges; and at the same time, a limiting clamping block drives a push-pull rod to slide in a bearing plate under extrusion of the ratchet wheel and extrudes a first spring, and then the first spring is pressed to rebound to push the limiting clamping block to mesh and fix the ratchet wheel, so the angle of the main body is conveniently adjusted, and the angle requirement of a user during writing is conveniently met.

Description

technical field [0001] The invention relates to the technical field of preventing myopia, in particular to a neck restraint device for preventing approaching of writing. Background technique [0002] Existing students often make their heads close to the table when they are not paying attention when writing, which will cause great damage to the neck and eyes of the students, especially when the students are in the stage of physical development during school, this situation will also affect the students' health. Development of the neck and eyes. [0003] Most of the existing technologies use corrective chairs to correct the students' sitting posture, but this method can only assist in correcting the students' back posture, and can protect the students' eyesight, but there is no restriction on the students' neck Orthodontics, therefore providing a neck restraint device for writing anti-adjacent. Contents of the invention [0004] The object of the present invention is to pr...
