Catch structure of rotary cover plate of circular sawing machine
First Claim
1. A catch structure of a rotary cover plate of a circular sawing machine, comprising:
- a rotary cover plate rotatably mounted on an outer side of an upper blade guard of a circular sawing machine, the rotary cover plate stopped and positioned on an outside of a substantially semi-circular hole of the upper blade guard to cover the substantially semi-circular hole of the upper blade guard, and a sector-shaped transparent lower blade guard oppositely pivoted on an outer side of the rotary cover plate, so that the sector-shaped transparent lower blade guard may be rotated relative to the rotary cover plate;
wherein, the rotary cover plate has an inner side protruded with a first catch end which may be moved with rotation of the rotary cover plate, to be stopped and positioned on a side wall of the semi-circular hole of the upper blade guard, and the rotary cover plate has an outer side protruded with a second catch end which may be oppositely stopped on a lug of a bottom edge of the sector-shaped transparent lower blade guard.

Abstract
The present invention relates to a catch structure of a rotary cover plate of a circular sawing machine. A rotary cover plate is rotatably mounted on an upper blade guard of a circular sawing machine, to cover a semi-circular hole of the upper blade guard. A lower blade guard is pivoted on the rotary cover plate, so that the lower blade guard may be rotated relative to the rotary cover plate. The rotary cover plate has an inner side protruded with a first catch end which may be stopped and positioned on a side wall of the semi-circular hole. The rotary cover plate has an outer side protruded with a second catch end which may be stopped on a lug of a bottom edge of the lower blade guard.
