Compound saw with double-shield interlocking mechanism

The utility model relates to a compound saw with a double-shield interlocking mechanism, in the compound saw, a machine body is provided with a base and a rack arranged above the base, the rear end of the rack is rotatably connected to the base, so that the front end of the rack swings up and down relative to the base, and the compound saw is correspondingly in a beveling mode or a table cutting mode; the limiting rod is arranged in the rack in a transverse extending mode, so that the limiting rod drives the first limiting part and the second limiting part to abut against the first protective cover and the second protective cover of the lower cover correspondingly in the reciprocating motion process in the extending direction of the limiting rod, locking of the double protective covers is achieved, or abutting of the first protective cover and the second protective cover is disengaged, and locking of the double protective covers is achieved. By means of the design form of the limiting rod, a complex locking m
