Small double disk saw assembly

Abstract

The invention discloses a small double disk saw assembly for machining electric appliance installation square holes. The small double disk saw assembly comprises end plates, bolts, a shaft, a motor, disk saws, a spline housing, a poking ring, a screw rod and a nut, wherein the two end plates are connected through the four bolts to form a saw frame; the spline shaft is installed in holes of the twoend plates; one disc saw is fixedly connected to one side of the shaft; the spline housing is movably connected to the other side of the shaft; the other same disc saw is installed on the spline housing; a groove is formed in the outer circle of the spline housing; the poking ring is movably connected into the groove; one end of the screw rod is connected to the poking ring; the other end of thescrew rod is screwed into the nut installed on one end plate; the nut is rotated to push and pull the screw rod, the poking ring and the like so that the distance between the two disc saws can be adjusted; the motor is mounted on the other end plate; a motor shaft is connected with the shaft; and handles are disposed on the end plates. By means of the small double disc saw assembly, the square holes which are different in size can be formed by machining, and labor and time are saved.

Description

technical field [0001] The invention relates to an electric tool for processing square or rectangular electrical instrument square holes, especially a double circular circular saw capable of processing small holes of different sizes. Background technique [0002] At present, it is necessary to drill square holes to install electrical appliances and instruments. Traditionally, a drill bit is used to drill many holes and then manually turn them into square holes. Contents of the invention [0003] In order to overcome the above-mentioned deficiency of laborious and time-consuming drilling of square holes, the object of the present invention is to provide a small double circular saw capable of processing square holes of different sizes. [0004] The technical solution adopted by the present invention to solve the problem is: it includes end plates, bolts, shafts, motors, circular saws, spline sleeves, dial rings, screw mandrels, and nuts, and the two end plates are connected ...
