Abstract

The utility model discloses a folding ruler, which belongs to a mathematical education supply. The folding ruler is implemented in the following steps: the left end part of a lever ruler is movably connected with a chute ruler, the outer edge of the chute ruler is provided with scale lines, the top end of the chute ruler is provided with a chalk sleeve, a ruler body of the chute ruler is provided with a chute, a raised connecting shaft is arranged in the chute, the connecting shaft is connected with one end of a connecting ruler, the other end of the connecting ruler is movably connected with the right end of the lever ruler, the end part of the right end of the lever ruler is provided with a rotating shaft, and the rotating shaft is provided with a sucking disc. The folding ruler disclosed by the utility model is simple in structure and easy to use; and in the process of drawing a straight line, the chute ruler can be directly used as a compass, and after the sucking disc at the right end of the lever ruler is adsorbed to a blackboard and then a chalk is arranged in the chalk sleeve on the chute ruler, the folding ruler can be used.

Description

A kind of folding chi
Technical field:
The utility model belongs to the mathematical education articles for use, particularly a kind of folding chi.
Background technology:
In mathematical education, especially in the several teaching, often need draw various geometric figures; At this moment teacher often need carry picture teaching aids such as set square, compasses, and each teaching aid function singleness is also inconvenient when the teacher carries; Also to change every now and then during use, use also more time-consumingly, use more though some folding chi can satisfy a chi; But making bowlder,, therefore be difficult on the blackboard fixing doing the bowlder stitch on the blackboard because the end of ruler is provided with stitch.
The utility model content:
The purpose of the utility model is the deficiency that overcomes the problems referred to above, and a kind of folding chi is provided, and this folding chi is achieved in that in the left part of handle chi and is connected with the chute chi; The outer of chute chi is provided with graduation mark, is provided with chalk sleeve on chute chi top, on chute chi body, is provided with chute; In chute, be provided with outstanding connecting axle; Connecting axle connects with an end that is connected chi, and the other end of said connection chi is connected with the right-hand member of handle chi is movable, and the right-hand member end of said handle chi is provided with rotating shaft; Rotating shaft is provided with sucker; In order to make handle chi, chute chi and to be connected the folding convenience of chi, connecting chi is the sleeve pipe telescopic structure, that is to say in the outer tube that connects chi to be provided with inner sleeve.
The utility model is simple in structure, and is easy to use, when drawing straight line, can directly use the chute chi, does the compasses time spent, and the sucker of handle chi right-hand member is adsorbed on the blackboard, can use behind the chalk of on the chute chi, packing in the chalk sleeve.
Description of drawings:
Accompanying drawing 1 is the structural representation of the utility model, 1, chalk sleeve 2, connect chi 2-1, inner sleeve 2-2, outer tube 3, sucker 4, rotating shaft 5, handle chi 6, chute 7, connecting axle 8, chute chi
The specific embodiment:
With reference to accompanying drawing 1 explanation as follows: a kind of folding chi is achieved in that in the left part of handle chi 5 to be connected with chute chi 8 that the outer of chute chi 8 is provided with graduation mark; Be provided with chalk sleeve 1 on chute chi 8 tops; On chute chi body, be provided with chute 6, in chute 6, be provided with outstanding connecting axle 7, connecting axle 7 connects with an end that is connected chi 2; The other end of said connection chi 2 is connected with the right-hand member of handle chi 5 is movable; The right-hand member end of said handle chi 5 is provided with rotating shaft 4, and rotating shaft 4 is provided with sucker 3, in order to make handle chi 5, chute chi 8 and to be connected the convenience that chi 2 folds; Connecting chi 2 is the sleeve pipe telescopic structure, that is to say in the outer tube 2-2 that connects chi 2 to be provided with inner sleeve 2-1.
