Problems solved by technology

When using chalk writing on the blackboard, some new chalks are sometimes broken, and the length of the broken chalks becomes shorter, which makes it difficult to use the short and broken chalks. Sometimes people simply throw them away, resulting in many short and broken chalks waste of
[0003] In view of the above phenomenon, people directly use a simple long tube body, and insert short and broken chalks in the tube for direct use, but after using the chalk, some chalks still remain in the simple tube body, which is difficult to take out, and sometimes due to Chalks come in different lengths and are not comfortable enough to use

Abstract

The invention discloses a clamping position balance adjustment short and broken chalk matched use device and method, and relates to the field of teaching facilities. According to the use device, a fifth supporting ring body is movably mounted on an inner side guide shaft rod; the inner side guide shaft rod is sleeved with a tension spring located between a first inner side guide plate and the fifth supporting ring body; the fifth supporting ring body is provided with a fifth lower clamping ring protrusion movably installed on a fourth upper side ring groove in a fourth inner side sleeve in a clamped manner; and a plurality of embedded clamping rollers are embedded into the ring side of the fifth supporting ring body; a third clamping ring body is mounted at the front end of a first inner side sleeve in a threaded manner; a third front side rubber clamping ring is arranged at a front side opening of the third clamping ring body; and a third front side silica gel ring is arranged at theinner side of the third front side rubber clamping ring. According to the use device, the length of chalks can be conveniently exposed and adjusted according to the actual length of short and broken chalks, so that the short and broken chalks are more convenient and comfortable to use, and the secondary breakage of the chalks can be avoided.

Description

technical field [0001] The invention belongs to the field of teaching facilities, and in particular relates to a supporting device for using short-cut chalk with card position balance adjustment and a using method thereof. Background technique [0002] In classroom education and teaching activities, whether in traditional classrooms or modern smart classrooms, blackboard writing on the blackboard is very common and necessary. Writing on the blackboard is usually done with chalk. When using chalk writing on the blackboard, some new chalks are sometimes broken, and the length of the broken chalks becomes shorter, which makes it difficult to use the short and broken chalks. Sometimes people simply throw them away, resulting in many short and broken chalks waste. [0003] In view of the above phenomenon, people directly use a simple long tube body, and insert short and broken chalks in the tube for direct use, but after using the chalk, some chalks still remain in the simple t...
