Detailed Description

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.

Referring to fig. 1-4, the present invention provides an embodiment: the utility model provides a can prevent pencil of scratch with aluminium matter set-square, includes handwriting 1, and aluminum plate 2 is installed at handwriting 1's top, and aluminum plate 2's internally mounted has rubber 3, and the surface cover of handwriting 1 is equipped with protection casing 4, and recess 5 has been seted up at the top of 4 internal surfaces of protection casing, and the internally mounted of recess 5 has spring 6, and rubber block 7 is installed to the one end of spring 6.

In this implementation, the scale groove that the position is corresponding and size looks adaptation is all seted up to the surface of handwriting 1 and protection casing 4, and the object can be measured to the scale groove.

In this implementation, the quantity of recess 5, spring 6 and block rubber 7 is three and equally divide into three groups, and three group's recesses 5, spring 6 and block rubber 7 are the mounting means setting of annular array at the internal surface of protection casing 4, make things convenient for protection casing 4 at the external fixed surface of pen body 1 and aluminum plate 2 through three group's recesses 5, spring 6 and block rubber 7.

In this implementation, the outer surface of the pen body 1 is provided with a clamping groove corresponding to the position of the rubber block 7 and matched with the size, and the rubber block 7 is conveniently clamped and fixed through the groove on the outer surface of the pen body 1.

In this implementation, aluminum plate 2's surface is seted up and is corresponded and the draw-in groove of size looks adaptation with 7 positions of rubber block, makes things convenient for rubber block 7 to block fixedly through the recess of aluminum plate 2 surface.

In the embodiment, the pen body 1 and the aluminum plate 2 are both in the shape of an equilateral triangle, and the design of the equilateral triangle is convenient for a user to hold.

The working principle is as follows: slide protection casing 4 to a definite position when needs use, it is fixed in the draw-in groove that spring 6 and rubber block 7 removed to aluminum plate 2 surface, can play certain safeguard effect to aluminum plate 2 through protection casing 4, when drawing needs measuring object length, scale through handwriting 1 and aluminum plate 2 surface can conveniently be measured, when need not use this pencil, slide protection casing 4 to a definite position, spring 6 compression expansion drives rubber block 7 and removes to fix in the draw-in groove of handwriting 1 surface, thereby can play certain guard action to the nib of handwriting 1.
