Spacing-adjustable scribing ruler

Abstract

The invention discloses a distance-adjustable scribing ruler, and belongs to the technical field of stationery. The scribing ruler comprises a plurality of ruler plates and a clamping jaw type distance adjusting mechanism, a screw rod is mounted in the middle of the main support; a nut is mounted on the screw rod; a plurality of guide sliding rods are symmetrically mounted on the main support along the two sides of the screw rod; the guide sliding rods are opened towards different angles, the guide sliding rods are sleeved with sliding blocks in a sliding mode, each sliding block is connectedwith a ruler plate, a linkage supporting rod penetrates through the nut, the linkage supporting rods are connected to all the sliding blocks in a penetrating mode at the same time, and when the nut does reciprocating linear motion along the lead screw, each sliding block is driven by the corresponding linkage supporting rod to slide along the corresponding guide sliding rod. Side supports are arranged on the two sides, and a scribing push frame is slidably connected between the side supports. By means of the multiple ruler plates and the clamping jaw type distance adjusting mechanism, multi-row scribing can be conveniently conducted, the distance between the ruler plates can be flexibly adjusted, scribing between the ruler plates can be conveniently and efficiently conducted, the efficiency is high, and use is convenient.

Description

technical field [0001] The invention relates to a ruler capable of marking lines and belongs to the technical field of stationery. Background technique [0002] Existing rulers are less efficient when multi-line grids are used. For example, when writing articles or answering questions in exams, if you do not type multi-line grids, it is easy to write crookedly and untidyly.
