The invention discloses an electric tool. The electric tool comprises a first clamping jaw, a second clamping jaw, a mounting support and locking pins. The first clamping jaw comprises a first clamping portion and a first stress portion. The second clamping jaw comprises a second clamping portion and a second stress portion. The mounting support is used for mounting the first clamping jaw and the second clamping jaw. The locking pins can move relative to the mounting support. The first clamping claw further comprises a first rotary shaft portion. The first rotary shaft portion is located between the first clamping portion and the first stress portion. The second clamping jaw further comprises a second rotary shaft portion. The second rotary shaft portion is located between the second clamping portion and the second stress portion. Each locking pin is at least provided with a locked position and an unlocked position when moving relative to the mounting support. Each locking pin is in contact with the first stress portion at least when on the locked position. Each locking pin is gradually close to the first clamping portion when moving from the unlocked position to the locked position. The first clamping jaw rotates so that the first clamping portion can be close to the second clamping portion. By the adoption of the electric tool, a tool accessory can be assembled and disassembled quickly.
