Abstract
The utility model discloses a clock which comprises a positive plate contact device and a trigger switch. The positive plate contact device comprises a main clamping plate; a circuit board disposed on the clamping plate; a handle shaft, one end of which is inserted into the main clamping plate; and a positive plate which is fixed on the main clamping plate. The positive plate is provided with an elastic gear pulling arm, and an elastic contact arm which contacts with a positive pole welding pad of the circuit board. The gear pulling calabash of the handle shaft compresses the elastic gear pulling arm in a buckling manner. The elastic contact arm compresses the positive pole welding pad of the circuit board under the action of an elastic force of the elastic gear pulling arm. According to the utility model, the handle shaft always compresses the elastic gear pulling arm of the positive plate, and enable the elastic gear pulling arm to deform downwards. The elastic contact arm of the positive plate and the elastic gear pulling arm of the positive plate are respectively one part of the positive plate.
