Problems solved by technology

[0005] However, although these two patents can install the quick release device on the riving knife or disassemble it from the riving knife, the structure of the quick release device of the two patents is relatively complicated, and it will cost a lot of time when installing or dismounting. The time is also longer, which is likely to cause inconvenience to the user in the operation

Abstract

The invention discloses a quick disassembling structure for a protecting cover component of a circular saw, which comprises a connecting support, a shaft part and a deflector rod, wherein the connecting support is provided with two side walls and a clamping groove formed between the two side walls, the two side walls are provided with a through hole respectively, the clamping groove is used for acleaver to embed, the shaft part passes through two through holes of the connecting support and is provided with an embedding section which is received in a receiving part of a notch of the cleaver, two planes are formed at the side periphery of the embedding section, and the deflector rod is fixed on the shaft part, thus the quick disassembling structure can ensure that a check pawl component ora cover is quickly assembled on the cleaver or disassembled from the cleaver.

Description

technical field [0001] The invention relates to a circular saw machine, in particular to a quick-release structure for a circular saw machine cover assembly. Background technique [0002] U.S. Patent Publication No. 2007 / 0113714 and No. 2007 / 0113715 respectively disclose a guide system for a power sawing machine. The guide systems of the two patents mainly include a rivet and a Quick release device. [0003] In the patent case No. 2007 / 0113714, the quick release device includes a support base, a lock block and two fixing bolts, wherein the bottom of the lock block has a slot for embedding of a chopper, and the two fixing bolts pass through the support base respectively The left and right sides of the locking block are used to combine the support seat and the locking block, and one of the fixing bolts passes through the fixing hole of the riving knife to fix the riving knife in the slot of the locking block. When the user wants to remove the quick release device from the ri...
