Electric tool impact block structure of improvement

The utility model relates to an electric tool technical field, in particular to electric tool impact block structure of improvement, including impact block, transmission shaft and impact spring, impact block installs in the transmission shaft, it cup joints in the transmission shaft to assault the spring, impact block includes cylinder and spacing disc, still include the rolling device, the rolling device includes the inner circle, outer lane and steel ball, the steel ball sets up between inner circle and the outer lane, the outside upset in edge of inner circle forms interior hem, infolding margin system steel ball drops between inner circle and outer lane, the inner circle cup joints in impact block's cylinder, and support and lean on in spacing disc, strike spring one end to leaning on in the rolling device, the other end supports the spacing step that leans on in the transmission shaft. Because the utility model discloses a steel ball adopts inner circle and outer lane fixed, and the rolling device is equivalent to a simple and easy thrust bearing, and the preparation of rolling device is fairly simple, and manufacturing cost is lower, and the structural cancellation annular groove of impact block makes impact block simple structure, easily production, cost reduction.
