Problems solved by technology
[0002] The saw blade of the electric circular saw will cause harm to the human body under high-speed rotation. In order to avoid the occurrence of the injury, many safety solutions have been proposed; for example, there are safety plans for the electric circular saw blade: There is a movable shield on the outer cover of the blade; in this way, the saw blade will not be exposed in a free state, and will not cause harm to the human body; however, the prior art uses a manual fixing method to fix the movable shield, that is, it needs It is very inconvenient to manually fix with screws and other fasteners, whether it is disassembling the movable shield or installing the movable shield
[0003] The existing electric circular saw does not have the switch protection function, and it is easy to cause harm to the human body when the switch is accidentally triggered. Therefore, we propose an electric circular saw with a switch protection mechanism to solve the above problems

The invention discloses an electric circular saw with a switch protection mechanism. The electric circular saw comprises a shell; a sealing groove is formed in a handheld part of the shell; a placing tank is formed in the center position of the inner wall of one side, far from an opening of the sealing groove, of the sealing groove; a moving mechanism is arranged on the inner wall of one side, far from an opening of the placing tank, of the placing tank; a movable plate is movably mounted in the placing tank; a power supply switch is fixedly mounted on the movable plate; the moving mechanism and the movable plate are matched for driving the power supply switch to move to the outer side of the placing tank from the inner side of the placing tank or to the inner side of the placing tank from the outer side of the placing tank, and adjusting the angle of the power supply switch; and a sealing mechanism is arranged on the inner wall of one side of the sealing groove, and is used for sealing or opening the sealing groove. The electric circular saw achieves the switch protection function, can prevent harm to human bodies caused by accidental triggering of a switch, and is simple in structure and convenient to use.
Description
technical field [0001] The invention relates to the technical field of electric circular saws, in particular to an electric circular saw with a switch protection mechanism. Background technique [0002] The saw blade of the electric circular saw will cause harm to the human body under high-speed rotation. In order to avoid the occurrence of the injury, many safety solutions have been proposed; for example, there are safety plans for the electric circular saw blade: There is a movable shield on the outer cover of the blade; in this way, the saw blade will not be exposed in a free state, and will not cause harm to the human body; however, the prior art uses a manual fixing method to fix the movable shield, that is, it needs Fasteners such as screws are manually used for fixing, which is very inconvenient no matter when the movable shield is disassembled or when the movable shield is installed. [0003] The existing electric circular saw does not have the switch protection fun...
