Embodiment Construction

[0036] Hereinafter, embodiments of the present invention will be described based on FIGS. 1 to 10 . FIG. 1 shows a table-top circular saw 1 according to the present embodiment. The table circular saw 1 includes a table 2 to which the cutting member W is fixed, and a cutter body 10 supported on the table 2 and capable of moving up and down with respect to the table 2 . The table 2 is supported on the upper surface of the base 3 in a horizontally rotatable manner. A positioning fence 4 for positioning the cutting material W is arranged on the upper surface side of the table 2 . The positioning guardrail 4 is mounted on the base 3 side and has a small gap with the upper surface of the table 2 , and the gap is small enough as long as it does not interfere with the upper surface of the table 2 .

[0037] A support arm 6 is provided on the rear portion (the right end portion in FIG. 1 ) of the table 2 with the left-right tilt operation support portion 5 interposed therebetween. A...

Abstract

The invention relates to a desk circular saw machine. The begone stopper member is pressed on the side of the safety cup to form moving resistance, therefore the safety cup maybe not rotate smoothly, wherein the stopper member is used to locking the safety up which rotates relative to cutter shield to switch the cutter at the dead point on the main body of cutting-off machine to make it not open. In the said invention, even the stopper member is bunted with the side, the safety cup will rotate smoothly. The stopper member (41) is separated into stopper supporter (42) and stopper main body (43), and a second energizing unit (43b) is mounted betweent the two parts, to make the energized force on the restrict part (43a) of the stopper main body (43) less than the first energized force of the dead point locking mechanism.

Description

technical field [0001] The present invention relates to a table-top circular sawing machine for cutting a cutting member fixed on a table by moving a cutting machine main body up and down. Background technique [0002] Such a table-top circular saw has a table for fixing the cutting material, and a cutter body supported on the table so as to be movable up and down, and the cutter body has a circular saw blade that is rotated by a motor. [0003] Approximately half of the upper side of the saw blade is covered by the blade guard, and approximately half of the peripheral portion of the lower side of the saw blade protruding downward from the blade guard is covered by the safety cover. The safety cover is opened and closed in conjunction with the vertical movement of the cutter body. That is, when the main body of the cutter moves downward, the safety cover is gradually opened to expose the saw blade, so that the cutting operation can be performed by pressing the exposed porti...
