Description
Technical field
The invention belongs to electric tool class technical field, particularly relate to a kind of bull electric screw driver.
Background technology
At present, conventional electric screw driver, is all that the end of bull stick is provided with rotary head by driven by motor bar rotation, being provided with hexagonal hole in rotary head, and band is magnetic, hexagonal hole is used for placing screws cutter head, driver bit is provided with hexagonal tail end, is inserted in hexagonal hole, just matches with hexagonal hole.Bar rotation drives driver bit to rotate, and coordinates to fall along beginning, screw is tightened and unscrews.But this electric screw driver only one of which driver bit, can only carry out degree of tightness to single screw.For multiple arranging screws together, and the screw that relative spacing is fixing, installation or removal one by one, time-consuming, effort.Such as: each electric energy meter all has 8 screws, and it is relative between two, the line of live wire, zero line is compressed, when verification and installation electric energy meter, it is both needed to unclamp eight screws one by one, being tightened one by one by eight screws again after having verified, not only time-consuming, effort also leverages work efficiency.
Summary of the invention
It is an object of the invention to the deficiency for above-mentioned electric screw driver, it is provided that a kind of bull electric screw driver.Realize the purpose of the present invention to be adopted the technical scheme that: a kind of bull electric screw driver, include hands handle, motor, two-direction switch, motor switch, bull stick, sheath, rotary head and driver bit, wherein, hexagonal hole it is provided with in rotary head, the driver bit of hexagon tail end it is provided with for plug-in mounting, bull stick hole and rotary head groove it is provided with in sheath, it is characterized in that: described rotary head is provided with external tooth, rotary head is gear-like, match with rotary head, a left side for rotary head, the right side is respectively provided with a driven rotary head, driven rotary head is respectively equipped with driven external tooth, it is respectively equipped with hexagonal hole in driven rotary head, the driver bit of hexagon tail end it is provided with for plug-in mounting, and the external tooth of rotary head is meshed with the driven external tooth in driven rotary head, rotary head rotates, driven rotary head is driven to rotate.Described driven rotary head is provided with fixing axle, is provided with fixed shaft hole in described sheath, and the fixing axle in driven rotary head is inserted in fixed shaft hole and matches, and is used for stablizing driven rotary head, rotary head and driven rotary head and is located in rotary head groove.During use, when an alone driver bit, only need to arranging driver bit in rotary head, driven rotary head is without placing rotary head, or only arranges driver bit in a driven rotary head, without placing rotary head in other rotary head and another driven rotary head.Such present invention is used aloned as existing electric screw driver.To, during with two driver bits, respectively arrange a driver bit in driven rotary head, without placing rotary head in rotary head.When opening motor switch, rotary head rotates, and under the engagement of external tooth, drives driven rotary head rightabout to rotate, and coordinates two-direction switch, the i.e. rotating of adjustable rotary head.It is used for two screws being installed or removed simultaneously simultaneously.The present invention, through on probation on electric energy meter, improves nearly one times of work efficiency.
The present invention can install or remove two screws simultaneously, be used especially in verification and install electric energy meter operation on save time, laborsaving, substantially increase work efficiency.
