Abstract

The invention provides a portable cutting machine which comprises a shell, a swing output shaft, a motor, a transmission mechanism and a saw blade. The swing output shaft partially extends out of the shell and outputs swing, the motor is accommodated in the shell and outputs rotation, the transmission mechanism is accommodated in the shell and converts the rotation of the motor into the swing of the swing output shaft, the saw blade is mounted on the swing output shaft to cut workpieces in a swing manner and has a cutting direction, a fan is arranged in the shell, an air inlet hole is arranged on the shell, the shell is provided with an air outlet which is close to the saw blade and faces the saw blade, an air channel is formed between the fan and the air outlet, and airflow flows in the air channel. The portable cutting machine has the advantages that the saw blade is prevented from being too hot in a cutting process, fingers of a user are prevented from being scalded when the user replaces the saw blade, and the problem that an existing saw blade is easy to break due to overheating is avoided.

Description

technical field [0001] The invention relates to a portable cutting machine, in particular to a portable cutting machine which swings and cuts workpieces. Background technique [0002] Existing portable cutting machines that drive saw blades to swing and cut workpieces are equipped with a motor, an eccentric part driven by the motor, a shift fork that cooperates with the eccentric part to convert rotation into swing, and a swing output shaft driven by the shift fork. , and the saw blade mounted on the swing output shaft. [0003] During the cutting process of the portable cutting machine, the workpiece is cut by the saw blade. In this process, the friction between the saw blade and the workpiece is very severe, resulting in a very high temperature of the saw blade, which leads to the The sheet breaks easily and burns the user easily. Contents of the invention [0004] The invention provides a portable cutting machine, in particular a portable cutting machine with a saw bl...
