Electric circular saw with dust collection function

Abstract

The invention relates to the technical field of electric circular saws, and discloses an electric circular saw with a dust collection function, which comprises an electric saw shell, a driving motor, a saw blade, an adjusting plate and a collection assembly, the driving motor is located on the back of the electric saw shell, the saw blade is located on an output shaft of the driving motor, and a protective cover is arranged on the outer side of the saw blade and connected with the electric saw shell. A handle is arranged on the side, close to the protective cover, of the electric saw shell, the adjusting plate is located under the saw blade and the handle and connected with the lower surface of the electric saw shell through the adjusting assembly, the adjusting assembly enables the adjusting plate to move vertically and adjust the angle, and the collecting assembly is connected with the protective cover. The distance between the installation protruding block and the installation plate is adjusted through the telescopic rod in the adjusting assembly, when the cutting depth of a cut object needs to be specified, the length, exposed out of the portion below the saw bite, of the saw blade is changed, the cutting depth can be controlled, workers can cut the object more conveniently and rapidly, and the cutting error of the cut object is smaller.

Description

technical field [0001] The invention relates to the technical field of electric circular saws, in particular to an electric circular saw with dust collection. Background technique [0002] A circular saw refers to a sawtooth tool used to cut steel. The existing circular saw is composed of a frame, a motor, a workbench, a protective cover, a guide plate, a shift mechanism, an electromagnetic starter, a circular saw blade, a spindle, The composition of the transmission mechanism. [0003] Existing hand-held circular saws with a dust extraction nozzle. Collect sawdust such as dust and powder generated by cutting. During the suction, because the middle of the protective cover is penetrated, some sawdust will follow the airflow to rush the suction nozzle to be discharged, but some sawdust will follow the saw blade to drive the air generated by the air to flow from the air. The other end of the protective cover is discharged, so that some sawdust cannot be collected, and when cu...

AI Technical Summary

Problems solved by technology

Collect the dust powder and other sawdust produced by cutting. During the suction, because the middle part of the protective cover is penetrated, some sawdust will be discharged from the suction nozzle with the air flow, but some sawdust will follow the air flow generated by the saw blade to drive the air from The other end of the protective cover is discharged, so that some sawdust cannot be collected, and when cutting, there are often some cuts with a specified depth. For example, in order to protect the inside of the object, only the surface part of the object can be cut, and some need to cut a certain slope. Angle cut marks, which require super strong control of workers, otherwise there will be cutting deviations and other phenomena
