Abstract
The utility model relates to a gear is quick screwdriver with higher speed, mainly by last handle, down the handle, take tooth steel wheel, steel shell, gear train, screwdrivers blade to form. Wherein: the gear train is installed in the steel shell, four total gears of gear train, and gear I and the meshing of gear II, gear I and gear II's drive ratio is 2: 1, gear III and the meshing of gear IV, gear III and gear IV's drive ratio is 2: 1, gear II and coaxial hard connection of gear III, the drive ratio of gear train is 4: 1. Take tooth steel wheel and gear I axle fixed connection, screwdrivers blade and gear IV axle fixed connection go up the handle and make by rigid plastic with handle down, go up the handle be fixed in take the tooth steel wheel on, leave the clearance with the steel shell to can be rotatory around the steel shell, the handle is fixed in on the steel shell down. The utility model has the advantage of scientific and reasonable design, work efficiency has been improved.
Description
Technical field
The utility model relates to gear and accelerates quick screwdriver, belongs to installation and maintenance technique with the apparatus field.
Background technology
In the work such as power equipment secondary installing, electric energy meter installation, often carry out the installation compared with small-sized screw with screwdriver, in the installation process of this screw, screw does not screw the front a very long time in the early stage needs less to screw power, but need multi-turn rotation just can screw, this just wastes a lot of man-hour.Moreover in the work such as Power Secondary line installation, need to screw or unscrew much such screw, waste a large amount of manpower.
Summary of the invention
The utility model overcomes the deficiency of prior art, provides a kind of gear to accelerate quick screwdriver, the ingenious difficult problem solving prior art and exist of the principle that this screwdriver utilizes gear to accelerate.
The technical solution of the utility model is: gear accelerates quick screwdriver, primarily of upper handle, lower handle, steel wheel with tooth, steel shell, gear train, driver bit composition.Wherein: gear train is installed in steel shell, gear train has four gears, gear I engages with gear II, the gearratio of gear I and gear II is 2:1, gear III engages with gear IV, the gearratio of gear III and gear IV is 2:1, gear II Hard link coaxial with gear III, and the gearratio of gear train is 4:1.Steel wheel with tooth is fixedly connected with gear I axle; Driver bit is fixedly connected with gear IV axle, and upper handle and lower handle are made by rigid plastics, and upper handle is fixed on steel wheel with tooth, leaves gap with steel shell, and can rotate around steel shell; Lower handle is fixed on steel shell.
The handle of conventional screw-driver in order is divided into independent two parts rotated up and down by the utility model, and driving gear set is established in inside, and the gearratio of gear train is 4:1.Because upper handle and steel wheel with tooth are fixing, bottom handle of a knife and steel shell are fixing, and that is when lower handle is fixing, top handle of a knife rotates one week, then driver bit rotates surrounding.When the initial moment of screw rotation is very little, operator to hold with a firm grip lower handle with left hand, upper handle is rotated, then driver bit meeting fast rotational, light screwing screw with the right hand, lower handle is unclamped when screw means needs larger torque, now, there is differential in gear train, and cutter head and handle just can synchronous rotaries, now just larger torque can be obtained, so that housing pin.During dismounting screw, first unclamp lower handle larger torque and screw is unscrewed, then, to hold with a firm grip lower handle with left hand, screw under fast rotary.
This device make use of the principle of gear up, when moment is little, is fixed by steel shell, now serves the effect increasing cutter head rotary speed.But when needing larger revolving force after screw means, this device is ingenious be make use of, and the principle of upper and lower gear differential self-locking, becomes 1:1 by gearratio, thus obtain larger torque.
The utility model design science is reasonable, improve operating efficiency, experimentally empirical data, use this device that a screw is installed and can save time about 15 seconds, a secondary line installer will mount and dismount thousands of screws every day, can raise the efficiency more than 40%.
Accompanying drawing explanation
Accompanying drawing is the utility model structural representation.
1, upper handle 2, lower handle 3, steel wheel with tooth 4, steel shell 5, driver bit 6, gear I7, gear II8, gear III9, gear IV.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Gear accelerates quick screwdriver, forms primarily of upper handle 1, lower handle 2, steel wheel with tooth 3, steel shell 4, driver bit 5.Wherein: gear train is installed in steel shell 4, gear train has four gears, gear I6 engages with gear II7, the gearratio of gear I6 and gear II7 is 2:1, gear III8 engages with gear IV9, the gearratio of gear III8 and gear IV9 is 2:1, gear II7 Hard link coaxial with gear III8, and the gearratio of gear train is 4:1.Steel wheel 3 with tooth is fixedly connected with gear I6 axle; Driver bit 5 is fixedly connected with gear IV9 axle, and upper handle 1 and lower handle 2 are made by rigid plastics, and upper handle 1 is fixed on steel wheel 3 with tooth, leaves gap with steel shell 4, and can rotate around steel shell 4; Lower handle 2 is fixed on steel shell 4.During use, when the initial moment of screw rotation is very little, operator to hold with a firm grip lower handle 2 with left hand, rotates upper handle 1 with the right hand, then driver bit 5 meeting fast rotational, light screwing screw, unclamps lower handle 2, now when screw means needs larger torque, there is differential in gear train, driver bit 5 and upper handle be 1 meeting synchronous rotary just, now just can obtain larger torque, so that housing pin.During dismounting screw, first unclamp lower handle 2 and by larger torque, screw is unscrewed, then, to hold with a firm grip lower handle 2 with left hand, screw under fast rotary.
