Abstract

The invention relates to a tool switching device which comprises a columnar part, a locking pin penetrating the columnar part in the radial direction, an elastic element sleeved on the columnar part, a protective sleeve wrapped on the columnar part and the elastic element, and a fastening device for fixing the protective sleeve. According to the invention, the device has wide applicability and universality; a user can replace switching devices provided with different tool heads according to the working requirements, and can use adapters with different functions in a matching manner through just using a tool body of the same electric tool, so that the purpose of convenience for mounting and dismounting can be achieved, and the reliability and economy of the device are improved.

Description

technical field [0001] The invention relates to the technical field of electric tools, in particular to a tool adapter device for quick connection and disassembly between a cutter and a machine head of an electric tool. Background technique [0002] Generally speaking, an electric tool uses a driving motor to rotate an internal rotor to drive a transmission shaft to rotate at a high speed, and then to rotate a tool assembled on the transmission shaft. [0003] Current power tools usually include a machine head and a working head. The machine head and the working head are detachably connected. There is a driving motor inside the body. Components rotate or vibrate. By connecting different working heads, electric tools can achieve different functions, such as: polishing, sanding, cutting, shoveling, etc. Therefore, the head of the electric tool and the working head can be quickly disassembled The structure is one of the key points of the design. The main point of this structur...
