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, be all by driven by motor bar rotation, the end of bull stick is provided with rotary head, be 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 in time matches with hexagonal hole.Bar rotation drives driver bit to rotate, and coordinates to fall along beginning, tightens and unscrew screw.But this electric screw driver only has a driver bit, degree of tightness can only be carried out 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 School Affairs installs electric energy meter, eight screws are all needed to unclamp one by one, tightened one by one by eight screws again after having verified, not only time-consuming, effort also have impact on operating efficiency greatly.
Summary of the invention
The object of the invention is the deficiency for above-mentioned electric screw driver, a kind of bull electric screw driver is provided.Realizing the technical scheme that object of the present invention takes is: a kind of bull electric screw driver, include handle, motor, two-direction switch, motor switch, bull stick, sheath, rotary head and driver bit, wherein, hexagonal hole is provided with in rotary head, being used for plug-in mounting is provided with the driver bit of hexagon tail end, bull stick hole and rotary head groove 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, hexagonal hole is respectively equipped with in driven rotary head, being used for plug-in mounting is provided with the driver bit of hexagon tail end, and the external tooth of rotary head is meshed with the driven external tooth in driven rotary head, rotary head is rotated, driven rotary head is driven to rotate.Described driven rotary head is provided with fixed axis, is provided with fixed shaft hole in described sheath, and the fixed axis in driven rotary head to be inserted in fixed shaft hole and to match, and be used for stablizing driven rotary head, rotary head and driven rotary head are located in rotary head groove.During use, when an alone driver bit, only need arrange driver bit in rotary head, driven rotary head without the need to placing rotary head, or only arranges driver bit in a driven rotary head, and other rotary head is interior without the need to placing rotary head with another driven rotary head.Such the present invention is used aloned as existing electric screw driver.To during with two driver bits, a driver bit is respectively set, without the need to placing rotary head in rotary head in driven rotary head.When opening motor switch, rotary head is rotated, and under the engagement of external tooth, drives driven rotary head rightabout to rotate, and coordinates two-direction switch, i.e. the rotating of adjustable rotary head.Be used for installing or removing two screws simultaneously simultaneously.The present invention, through on probation on electric energy meter, increases work efficiency nearly one times.
The present invention can install or remove two screws simultaneously, be especially used in School Affairs install electric energy meter operation on save time, laborsaving, substantially increase operating efficiency.
