Problems solved by technology

[0003] However, the above-mentioned mode of achieving impact through the locking groove has very limited impact force. Because the front and rear movement space of the locking groove is limited, the impact force is not enough, and the work efficiency is also low, so it cannot meet the impact work in a high environment.

Abstract

The invention discloses an impact tool. The impact tool comprises a rack, a motor contained in the rack, a transmission mechanism, an output shaft and an adjusting cup installed on the outer side of the rack, and the motor drives the transmission mechanism to rotate and drives the output shaft to do rotary output motion. The impact tool is provided with an impact mechanism and a rotation stopping part, the impact mechanism is provided with a movable ratchet fixedly held with the output shaft, an impact hammer axially sliding on the output shaft and an elastic piece sleeving the output shaft, and the movable ratchet and the impact hammer are provided with mutually coupled inclined planes; in an impact mode, the rotation stopping part abuts against the impact hammer, then the impact hammer can only move axially but cannot rotate, the impact hammer moves on the inclined plane, and an impact function is achieved under the release of the capacity of the elastic piece; and when only an electric drill mode is needed, a rotation stopping pin is separated from the impact hammer, the impact hammer and the movable ratchet rotate together, an impact mode with higher impact efficiency is achieved, and the working efficiency is improved.

Description

[technical field] [0001] The invention relates to an electric tool, in particular to an impact tool capable of working in impact mode and only in electric drill mode. [Background technique] [0002] Electric drills currently on the market provide at least two modes for convenience. For example, the two modes are a normal electric drill mode and an impact mode with impact. Please refer to the impact electric drill disclosed in Chinese Utility Model Patent No. CN206216621U published on June 6, 2017. When the screw is in gear position, the locking groove on the lower end surface of the adjustment ring contacts the limit protrusion of the jump pad. The locking platform on the upper end surface of the adjustment ring is in contact with the toggle lever of the impact conversion pad, that is, the jump pad is not locked at this time, the impact conversion pad is locked, and the jump pad moves up and down, so that the tooth box can Jump gear but can not impact; when the torque cover...
