Detailed Description
In order to solve the problems that the ruler has a single structure, a fixed shape and an unadjustable angle, a drawing tool needs to be frequently replaced during drawing, and the practicability is low, the function diagraph for mathematical education is particularly provided. The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Examples
Referring to fig. 1-4, the present embodiment provides a function diagraph for mathematical education, including a main scale 1, a placement groove 2 is opened on the front side of the top end of the main scale 1, a sliding groove 7 penetrating through the main scale 1 is opened in front of the placement groove 2, and an auxiliary scale 3 is disposed on the main scale 1.
The diagraph mainly comprises a main ruler 1 and an auxiliary ruler 3, wherein the auxiliary ruler 3 is installed on the main ruler 1, a placing groove 2 formed in the main ruler 1 is used for placing the auxiliary ruler 3, and a sliding groove 7 formed in the main ruler 1 is used for sliding the auxiliary ruler 3.
Wherein, vice chi 3 is passed through the hinge by straight board chi 31 and telescopic ruler 32 and is articulated to constitute, and the one end that straight board chi 31 kept away from telescopic ruler 32 passes through the hinge and articulates on standing groove 2 lateral wall, and the one end that telescopic ruler 32 kept away from straight board chi 31 passes through threaded traveller 6 slidable mounting in spout 7.
