Combined scribing instrument

Abstract

The invention discloses a combined scribing instrument consisting of a base, an upright post, a rocker arm shaft, a vertical shaft, a horizontal shaft, a positioning sleeve, a sliding sleeve and scratch awls, wherein the rocker arm shaft is parallel to the horizontal shaft; the scratch awls are respectively arranged at one end of the rocker arm shaft and one end of the horizontal shaft; and a short shaft is parallel to the vertical shaft; the scratch awls are respectively arranged at one end of the short shaft and one end of the vertical shaft and are respectively mutually connected and positioned through the sliding sleeve and the positioning sleeve so as to form a basic structure with two horizontal devices and two vertical devices. With the structures of the rocker arm shaft, the vertical shaft, the horizontal shaft and the short shaft and by up-down and left-right movement or rotation of the sliding sleeve, the invention not only can align, scribe and singly scribe on the plane, but also can scribe three-dimensional parallel lines, three-dimensional vertical lines, circles, side circles, tip circles and the like, thereby realizing multifunction by one machine and improving the efficiency and the precision for scribing.

Description

technical field [0001] The invention relates to a mechanical scribing device, in particular to a plane and three-dimensional scribing device. Background technique [0002] At present, the scribing instruments actually used in sales and production on the market are generally composed of a scribing plate, a column and a scribing needle. The scribing function is less, and it can only perform simple plane alignment and plane scribing. And it can only draw a single line. If you want to draw double parallel lines, multi-parallel lines, three-dimensional lines, or circles, you must use other tools to do it. The line marking function is single and the line marking efficiency is low. The marking accuracy is not high. Contents of the invention [0003] The object of the present invention is to provide a combined line marking instrument, which can not only perform simple line marking and alignment, but also can install multi-head marking needles according to actual needs, and can dr...
