Description

Electric wrench for mounting and dismounting scaffold top support Technical Field The utility model belongs to the technical field of building tools, and particularly relates to a wrench special for jacking a scaffold. Background The scaffold is a supporting structure which is extremely widely applied in the building field, when the template scaffold is installed, a scaffold jacking is needed, the scaffold jacking is an important bearing component and is mainly used for adjusting the top height of a scaffold upright rod and bearing upper load, the scaffold is divided into a screw rod type and a bolt type, and the scaffold is widely applied, wherein a screw rod type is widely applied, a regulating screw rod X is arranged in the middle of the scaffold, an adjustable bracket M is arranged at the top of the regulating screw rod X, a regulating nut Z is sleeved on the regulating screw rod X through a threaded matching sleeve, the upright rod N is connected with the regulating nut Z and is sleeved on the regulating screw rod X at the same time, and due to the complexity of the installation of the scaffold, a conventional spanner is not used for screwing the scaffold, and therefore, two side wings Y are fixedly processed on the coaxial two sides of the regulating nut Z. The existing screwing adjusting nut Z basically adopts a manual mode to take a pipe, then one end is propped against the side wing Y, and the other end is knocked by a hammer until adjustment is finished. Disclosure of Invention The utility model aims at providing a scaffold jacking and dismounting electric wrench special for screwing an adjusting nut, which is designed for the adjusting nut structure of the jacking. The utility model comprises a shell, a handle and a hand-held handle which is arranged at the front end of the handle and is fixed through a fastening bolt, wherein a motor and a battery are arranged in the handle, a bevel gear is arranged at the front end of a motor shaft, the bevel gear is meshed with a bevel gear, the bevel gear and the driving gear are fixedly arranged on a driving gear, the bevel gear and the driving gear are coaxially arranged on the shell through a driving shaft, the driving gear is meshed with a via gear, the via gear is arranged on the shell through a gear shaft, the via gear is meshed with an output gear, the output gear is sleeved on a cavity shaft, positioning rollers are arranged at two sides of the output gear on the cavity shaft, a guiding limit slide rail is arranged at the outer edge of the positioning rollers, the guiding limit slide rail is matched with the guiding limit slide rail, the guiding limit slide rail is arranged on a guiding locating piece, the guiding locating piece is fixedly arranged on the shell, a jacking bolt hole is arranged in the middle of the positioning roller, the shell, the guiding limit slide rail, the cavity shaft and the front end of the output gear is provided with a bolt channel communicated with the jacking bolt hole, the positioning roller is provided with a window corresponding to the positioning roller, and two torsion bars with the same axis are arranged at the side of the positioning roller.
