Electric tool for screwing screw

Abstract

The invention discloses an electric tool for screwing a screw. The electric tool comprises a transmission box with a transmission cavity, a rotating cylinder is rotatably connected to the lower end face of the transmission box, a screw sleeve is fixedly connected to the lower end face of the rotating cylinder, a sleeve cavity with a downward opening is formed in the screw sleeve, and a plurality of symmetrical clamping block cavities are formed in the sleeve cavity in an annular array and communicated mode. Sleeve blocks are horizontally and slidably connected into the multiple clamping block cavities, sleeve springs are fixedly connected between the end faces of the sides, away from the sleeve cavities, of the multiple sleeve blocks and the side walls, away from the sleeve cavities, of the multiple clamping block cavities, a vibration cavity is formed in the rotating cylinder, and a main power shaft and a crankshaft are arranged in the vibration cavity. The bottom end of the outer circle face of the main power shaft is fixedly connected with a driving bevel gear. When it is hard to screw out the screw, the cam pushes the swing rods on the left side and the right side to push the impact block to impact two sides of the screw sleeve, so that vibration on the left side and the right side is generated at the joint of the screw, and the screw difficult to screw out can be quickly loosened.

Description

technical field [0001] The invention relates to the field of electric tools, in particular to an electric tool for screwing. Background technique [0002] In the prior art, it is often encountered that the screw is difficult to unscrew. The difficulty in unscrewing the screw may be due to the adhesion caused by the long-term connection between the threads, or the corrosion caused by the humidity of the working environment. It is difficult to unscrew the screws more efficiently with advanced screw-screwing electric tools, which is easy to cause waste of time, that is, it is difficult to respond to the situation that various screws are difficult to unscrew, and it is difficult to meet the use requirements. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an electric tool for screwing, so as to solve the technical defect that the electric tool in the prior art cannot efficiently unscrew the screw that is difficult to...
