Document Type and Number:
WIPO Patent Application WO/2019/090892
Kind Code:
A1
Abstract:
Disclosed is a pressure-sensitive foldable electronic multi-functional optical grating positioning cutting ruler, comprising a connecting plate (1), a connecting shaft (2), a measuring ruler body (3) and a clamping mechanism (4). The connecting shaft (2) comprises an upper shaft (23) of a hollow structure, a lower shaft (25) and a limiting ring (24), the upper shaft (23) and the lower shaft (25) being mutually sleeved, and the connecting plate (1) being engaged with the connecting shaft (2). The measuring ruler body (3) is connected to the connecting plate (1), wherein a T-shaped slide groove (30) and a capacitive pressure sensor (32) are arranged inside the measuring ruler body (3), and a cutting tool carriage (33) is arranged above the T-shaped slide groove (30); an optical grating emitting device (336) is arranged on the cutting tool carriage (33); and the clamping mechanism (4) comprises a tension spring (41) and a C-shaped pressing plate (42). The pressure-sensitive foldable electronic multi-functional optical grating positioning cutting ruler has a rational structure, has the advantages of being simple in structure, being easy to use, being safe and reliable, being convenient to store, being easy to position, and being high precision, etc., and effectively solves the problem of low cutting precision of an existing cutting tool.
