Abstract
The utility model discloses a drill with a connector capable of being replaced fast. The drill with the connector capable of being replaced fast comprises an output shaft connector, a drill connector, a clamping sleeve, a spring, a shaft clamping spring and steel balls. One end of the output shaft connector is provided with an output shaft inserting hole, and the other end of the output shaft connector is connected with the drill connector. The clamping sleeve is placed outside the output shaft connector, and the spring is arranged between the output shaft connector and the clamping sleeve in a sleeved mode. One end, close to the output shaft inserting hole, of the clamping sleeve is fixed with the output shaft connector through the shaft clamping spring inside a clamping spring groove. Holes are formed inside the output shaft connector, and the steel balls are placed inside the holes. The clamping sleeve is used for fixing the drill connector through the steel balls. A spline design is adopted on the drill, the purposes of high efficiency, stable transmission and high coaxiality can be achieved, and the reliability of transmission is improved. The spring is used for pushing the steel balls to be positioned in a steel ball groove, so that the purposes of fast mounting and dismounting can be achieved. A cylindrical pin abuts against the spring, so that the connector can be replaced conveniently and fast, and meanwhile a safeguard role is played.
