Abstract
An electric tool includes a tool body and a clamping device configured to clamp an operating attachment. The clamping device includes a moving member, a biasing member, a limiting member, and a switching mechanism. The moving member is sleeved on the output assembly and has a locking position where the operating attachment is locked. The biasing member is configured to apply a biasing force to the moving member to keep the moving member in the locking position. The switching mechanism includes a toggle portion and a driven portion. The toggle portion is configured to be movable toward the tool body and drive the moving member to move in a direction away from the tool body to disengage from the locking position. The biasing member is configured to apply a biasing force to the driven portion to keep the moving member in the locking position.
