Abstract
The utility model relates to a fast rotating screwdriver. A straight screwdriver head and a cross-shaped screwdriver head are respectively arranged at the two ends of a screwdriver head; a six prismatic column body 10 is arranged in the middle of the screwdriver head at the two ends; a hexagonal hollow cavity is formed inside a hexagonal jack 2; and the six prismatic column body 10 of the screwdriver head can be enabled to be inserted into the hexagonal jack 2. A cylindrical hollow cavity is formed inside a screwdriver body. A gear 15 is arranged in the middle of a screwdriver rod and is in contact with three gears 8 with the same size, the three gears 8 with the same size are installed on sleeve frames at equal intervals; and one end of each sleeve frame is fixed with a clamping head. A gear ring is sleeved on the gears 8 with the same size and the gear 15. The clamping head is moved backwards without changing the rotating speed. The clamping head is moved forwards and is held by one hand, and the screwdriver body is rotated by the other hand to obtain quicker rotating speed when the rotating directions of the screwdriver rod and the screwdriver body are opposite. The fast rotating screwdriver has the beneficial effects that the screwdriver head can be conveniently and quickly changed, the screwdriver head can be quickly rotated when a screw is assembled or disassembled, and the work efficiency is effectively improved.
Description
Technical field
The utility model relates to a kind of screwdriver, specifically a kind of novel screwdriver of accelerating to rotate.
Background technology
In the prior art, the screwdriver loading and unloading screw that generally uses once can only rotate half-turn, and is very slow for more common many threaded screw handling speed, and hand is easy to fatigue.And conversion driver bit of the present invention is convenient and swift.
Summary of the invention
Technical problem to be solved by this invention is achieved through the following technical solutions: a kind of fast rotational screwdriver is by cutter head 1, hexagonal socket 2, and dop 3, casing rack 4, knife bar 5, the identical gear 8 of 7, three sizes of 6, two bearings of blade, gear ring 9 forms.It is characterized in that the cutter head two ends are respectively equipped with in-line cutter head and cross cutter head, two tool bit diameters are less than hexagonal socket 2 inside diameters, and cutter head middle part in two ends is provided with six prismatic cylinders 10.Hexagonal socket 2 inside are the hexagon cavity body, and guarantee that six prismatic cylinders 10 of cutter head can insert hexagonal socket 2.Hexagonal socket 2 inside are provided with magnet 16, and magnet can hold cutter head one end.Hexagonal socket 2 is fixed with knife bar.Knife bar one end is provided with six prismatic cylinders 11, and blade one end is provided with six prismatic cylinders 12.And six prismatic cylinders 11 and six prismatic cylinders, 12 front ends are slightly thin, so that dop is inserted in smoothly.Be circular in the dop front end, and dop is mobile before and after can be on knife bar, is respectively equipped with the hexagon cavity body in the middle part of the dop and in the rear end, and can be placed in respectively six prismatic cylinders 11 and six prismatic cylinders 12.Two bearings 7 are fixed in blade, and knife bar is installed on two bearings 7.
[0004] the inner cylindrical cavity body of blade.The knife bar middle part is provided with gear 15, gear 15 and three gear 8 contacts that size is identical, and the spacing of the gear 8 that its three sizes are identical equates to be installed on casing rack, and its casing rack one end and dop are fixed.Gear ring is placed in three gear 8 and gears 15 that size is identical, and gear ring and blade are fixed.When moving forward dop, the gear 8 that its three sizes are identical is followed mobile and is all contacted with the gear teeth of gear ring and gear 15, and all gears will be wider than the displacement of dop, in order to avoid three identical gears 8 of size break away from gear ring and gear 15.
[0005] the present invention compares with existing screwdriver and has following effect: but fast and easy conversion driver bit can be accelerated rotation, Effective Raise operating efficiency by cutter head when the installation or removal screw.

The specific embodiment
[0014] as required conversion in-line cutter head or cross cutter head of its cutter head.Mobile dop backward, two hexagon cavity body in the middle part of its dop and the rear end are placed in six prismatic cylinders 11 and six prismatic cylinders 12, and this moment, knife bar and blade were lock-out state, and rotating speed is constant.Move forward dop, separate with six prismatic cylinders 12 with six prismatic cylinders 11 with two hexagon cavity body in the rear end at the middle part of its dop, three identical gears 8 of size are followed and are moved and all contact with the gear teeth of gear ring and gear 15, be released state this moment, one holds dop, its casing rack is motionless, another hand-screw rotor body, its gear ring rotation, gear ring drive the identical gear 8 of three sizes on casing rack with the equidirectional rotation of blade, its driven gear 15 opposite spins have obtained the knife bar very fast rotating speed opposite with the blade direction of rotation.All gears will be wider than the displacement of dop, in order to avoid three identical gears 8 of size break away from gear ring and gear 15.
[0015] as required conversion in-line cutter head or cross cutter head of cutter head.During use: mobile dop backward, rotating speed is constant.Move forward dop, one holds dop, another hand-screw rotor body, and it obtains the knife bar very fast rotating speed opposite with the blade direction of rotation.
