Sleeve head for straight thread connection of steel bars

The utility model relates to a sleeve head for straight thread connection of steel bars. In the reinforced concrete structure, the mechanical connection of the steel bars are applied widely; especially for the mechanical connection of the steel bars of a raft plate in a basement, the connection heads of the steel bars are multiple, so that the workload is heavy. However, if the construction is carried out by using the traditional wrench in a manual operation manner, a large quantity of time and human sources are consumed, i.e., the construction period is restricted. The sleeve head provided by the utility model comprises a straight thread sleeve barrel (1), wherein one end of a screw rod (2) extends into the straight thread sleeve barrel; the other end of the screw rod extends into a nut (3); the nut is mounted in the sleeve barrel (5) of an electric wrench (4); and the steel bars (6) to be connected are mounted in the straight thread sleeve barrel. The sleeve head is used for for straight thread connection o
