Embodiment Construction

[0014] according to figure 1 As shown, the present embodiment can adopt the following specific design scheme:

[0015] The clamping structure 1 can be formed by plastic one-time processing, and its specific dimensions are respectively: a total length of 10 cm (or 7 cm), an inner diameter of 1.0 cm, a length of 4 cm or a length of 2 cm (when equipped with a short chalk B head). The hole is formed with a thick hole with an inner diameter of 1.6 cm and a length of 6 cm or a length of 5 cm (when a short chalk B head is used), and the hole wall thickness of the clamping structure 1 is greater than 1.2 cm.

[0016] Take a rubber elastic fine sleeve 2 with an inner diameter of 0.6 cm and a thickness of 0.15 cm and put it on the outer wall of the thin hole with an inner diameter of 1.0 cm and let it grow at least 1 cm from the end of the thin hole; take a thin tube with an inner diameter of 1.2 cm and a thickness of 0.15 cm The rubber elastic thick casing 3 is overcoated on the outer...

Abstract

The invention relates to a method for writing with a chalk clamping device by persons with disabled fingers and a structure of the chalk clamping device. The using method includes the steps of enabling the fingers (A) to be inserted into the thick hole end of the clamping device (1) , abutting against one end of a chalk (B) penetrated from the thin hole end in the thick hole end with the fingers (A), enabling the other end of the chalk (B) to be exposed out of the thin hole end, respectively tightening the exposed parts of the fingers (A) and the exposed part of the chalk (B) with the portions, extending out of the clamping device (1), of a rubber elastic thick sleeve (3) and a rubber elastic thin sleeve (2), and the part, exposed out of the rubber elastic thin sleeve (2), of the chalk (B) can be driven by the fingers (A) to complete the writing process on a blackboard. The structural mode is that the interior of the clamping device (1) is formed by a small caliber thin hole section and a large caliber thick hole section which are arranged in a front-and-back mode in a penetrated mode; in addition, the thin hole section and the thick hole section are sleeved with the rubber elastic thin sleeve (2) and the rubber elastic thick sleeve (3) respectively. The method and the structure are particularly suitable for teachers with the disabled fingers.

Description

technical field [0001] The present invention relates to a method for handicapped people to write with a chalk holding device and the structure of the chalk holding device Background technique [0002] At present, the chalk holding devices sold on the market for the continued use of short chalk all need the cooperation of two hands including the thumb to complete the writing work of driving the short chalk at the other end on the blackboard. It is quite a pity for the above-mentioned disabled people to use it for the disabled with the thumb. Contents of the invention [0003] Purpose of the present invention: just in order to solve above-mentioned " quite regrettable " problem. [0004] For realizing the object of the present invention, adopt following technology: [0005] The present invention utilizes the chalk clamping device method: let the finger penetrate the thick hole end of the clamping device and hold against one end of the chalk penetrating from the fine hole e...
