Abstract
The utility model relates to a two-way percussion-type electric wrench, which comprises a motor, a flywheel, a flywheel axle, a convex block on the flywheel axle, and a wrench. The utility model is characterized in that the flywheel is provided with a shaft pin which is sleeved by an impact block; two pulling springs on the flywheel are connected the impact block; the edge of the outside of the impact block is a concave groove with convex sides on two sides of the opening thereof; blocking pins are arranged on two ends of the concave groove; a sliding block is arranged in the concave groove; the impact block is matched with the convex block on the flywheel axle. The utility model has the advantages that the rotating direction of the percussion-type electric wrench can be easily changed.
Description
Technical field
The utility model relates to a kind of percussive electric wrench, particularly a kind of two-way percussive electric wrench.
Background technology
Widely used electric wrench is many in vehicle maintenance at present passes to flywheel with gear with motor power, flywheel with the energy that gathers to the axis lock that tights a bolt, and the reverse rotation again of when dismounting, some present percussive electric wrenches just need the piece that knocks in the percussive electric wrench to be turned to the steering structure complexity.
Summary of the invention
The purpose of this utility model is to solve the complicated awkward problem of piece steering structure of knocking in the percussive electric wrench in the prior art.Technical solutions of the utility model design a kind of two-way percussive electric wrench, comprise projection, spanner on motor, flywheel, flywheel shaft, the flywheel shaft, it is characterized in that: pivot pin is arranged on the flywheel, be with impact block on the pivot pin, have two extension springs to connect impact block on the flywheel, outer ledge is a Baltimore groove on the impact block, the Baltimore groove opening part has both sides that chimb is arranged, there is backing pin at the Baltimore groove two ends, and slide block is arranged in the Baltimore groove, and impact block cooperates with projection on the flywheel shaft.The utility model has the advantages that the direction of rotation that to change the percussive electric wrench easily.
