Cutting Angle Positioning Device for Circular Saw Machine

Abstract

A cutting angle positioning device is adapted for use in a miter saw. The miter saw includes a base seat and a scale disc that is formed with a plurality of notches. The positioning device includes aworking table, an elastic member, and a lever member. The working table includes a main portion and a mounting portion. The elastic member has a fixing portion, a movable portion, and a protruding portion that is connected to the movable portion. The lever member has a linking portion that is connected to the movable portion of the elastic member, and a handle portion. The elastic member can be converted from a locking state for engaging the protruding portion of the elastic member with the one of the notches to a releasing state, in which the protruding portion is disengaged from the one of the notches. The fixing portion is connected to the working table and the linking portion is connected to the movable portion to complete the mounting, thereby achieving the effect of simple fabrication and easy assembly.

Description

technical field [0001] The invention relates to a cutting angle positioning device, in particular to a cutting angle positioning device of a circular saw machine. Background technique [0002] refer to figure 1 , 2 , 3, a kind of cutting angle positioning device 1 of existing circular saw machine, as No. US6810780 of U.S. Patent of Invention, is used for a circular saw machine 15, and described circular saw machine 15 comprises a base 151, and a rotatable The working disk 152 that is located on the base 151, the working disk 152 includes a disk body 153, and a mounting portion 154 connected to the disk body 153, the cutting angle positioning device 1 of the circular saw machine includes a A positioning plate 11 , a positioning elastic piece 12 , a pivot member 13 , and a positioning lever 14 . [0003] The positioning plate 11 is disposed under the plate body 153 and includes a plurality of grooves 111 . The positioning elastic piece 12 is swingably arranged on the disc ...

AI Technical Summary

Problems solved by technology

[0005] However, in order to assemble the positioning lever 14 on the working disk 152, it is necessary to process the screw holes required for locking the connecting portion 132 on the mounting portion 154 and process the pivoting portion 143 for The circular hole pierced by the cylindrical part 131, and the cylindrical part 131 needs to be pierced through the pivotal part 143 first during assembly, and then the transfer part 132 is fixed to the mounting part 154, not only making Troublesome and complicated to assemble
