Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Referring to fig. 1-4, an adjustable h-square comprises a long ruler 1, a short cross ruler 3 and a long cross ruler 2, wherein the inner wall of the bottom end of the long ruler 1 is provided with an inner chute 12, the inner diameter width of the inner chute 12 is the same as the width of the short cross ruler 3 and the long cross ruler 2, the middle parts of the short cross ruler 3 and the long cross ruler 2 are respectively provided with a bulge, the middle parts of the inner sides of the bulges are respectively provided with a slot, the inner diameter width of the slot is the same as the outer width of the long ruler 2, the slot in the long cross ruler 2 is communicated, one sides of the short cross ruler 3 and the long cross ruler 2, which are not provided with the slot, are respectively provided with a cross ruler scale 31, the outer sides of the two sides of the long ruler 2 are respectively and symmetrically provided with a double scale 11, the middle part of the inner chute 12 is adhered with a middle non-slip-proof pad 13 through gum, so that the ruler body is not easy to deviate and slide on a paper surface, the outer sides of the bulges of the short cross ruler 3 and the long cross ruler 2 are respectively provided with a fixing hole, both ends of the long cross ruler 1 are respectively provided with a threaded hole, and a fixing screw 4 is vertically connected with the fixing hole on the outer wall of the bulges of the short cross ruler 3 and the long cross ruler 2, and the outer wall of the bottom end of the fixing screw 4 is connected with the threaded hole through threads, and the end part of the fixing screw 4 is provided with a cross open slot or a hexagonal flange, so that the fixing is convenient to fix through a screwdriver or a wrench.
