Problems solved by technology

[0003] However, the rechargeable electric cutters currently on the market need to be charged after use. Due to the aging of the internal circuit of the electric cutter, there will be a short circuit of the inner wall circuit when the electric cutter is charging, resulting in the temperature of the charging interface of the electric cutter. As a result, the charging interface of the electric cutter is burned, which leads to the occurrence of a fire, which causes a large economic loss and reduces the service life of the electric cutter.

Abstract

The invention relates to the technical field of electric tools, and discloses a rechargeable electric tool, which includes a housing, a protective cover 1 is movably connected to the outer side of the housing, and a protective cover 2 is movably connected to the outer side of the housing. A switch is fixedly connected to the outer side of the housing, a protective frame is fixedly connected to the outer side of the housing, and a cutting knife is movably connected to the outer side of the housing. When the rechargeable electric tool is working, through the provided heat conduction block and the cooperating conductive rod, more heat is generated through the heat conduction block during use, and then the contact between the conductive block and the electrical contact is pushed, so that the conductive rod has current passing through it. , and then promote the movement of the push plate, and then separate the charging port, so as to avoid the temperature rise of the charging interface of the electric cutter when the inner wall circuit is short-circuited when the electric cutter is charging, prevent the burning of the charging interface of the electric cutter, and prevent The occurrence of fire avoids large economic loss and improves the service life of the electric cutting knife.

Description

technical field [0001] The invention belongs to the technical field of electric tools, in particular to a rechargeable electric tool. Background technique [0002] Electric cutting tools are divided into two types: hand-held and movable. Hand-held electric cutting tools are often used in daily life, and most of them are rechargeable. Electric cutting tools are driven by motors. Electric cutting tools are widely used and can be used in industrial production lines. It can also be used for household products. As far as the trimming of flowers and trees in flower beds is concerned, it is necessary to use a rechargeable electric cutter to continue trimming, thereby increasing the efficiency of trimming. [0003] However, the rechargeable electric cutters currently on the market need to be charged after use. Due to the aging of the internal circuit of the electric cutter, there will be a short circuit of the inner wall circuit when the electric cutter is charging, resulting in the...
