Abstract

The invention discloses a multifunctional marking and sampling ruler. The multifunctional marking and sampling ruler is characterized in that main rulers and auxiliary rulers with different lengths are mutually hinged and lapped end to end to form a quadrilateral shape, and long strip-shaped holes are formed in the length direction of ruler bodies provided with scales, so that the main rulers and the auxiliary rulers can be adjusted randomly in the length direction and are locked and positioned by locking rotary knobs. According to the multifunctional marking and sampling ruler, a required material shape can be determined rapidly and conveniently and copied to a shearing material, and the working efficiency and the working quality are improved.

Description

technical field [0001] The invention relates to a tool ruler, in particular to a multifunctional marking sampling ruler. Background technique [0002] At present, in the field of bricklaying and carpentry, materials need to be cut according to the specific shape of the structure. The traditional method is to compare the unit material with the gap of the actual structure, then draw the line, determine the outline, and sample. This operation method requires repeated comparisons, which cannot be completed at one time, which seriously affects the work efficiency; at the same time, the method has no reliable positioning when marking the line, which has a great influence on the technical factors of the operator, and the size error is large, which affects the appearance of the structure. Poor sex. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a multifunctional marking sampling ruler, which can conveniently and quickl...
