Abstract
The utility model relates to a screwdriver with the rotation speed of a screwdriver rod being rapider than that of a handle; inside a shell, the transmission is realized by a gear pair, and a large gear is a driving gear, and a small gear is a driven gear, and the large gear is externally engaged with the small gear, and both of the large and the small gears are of a parallel shaft structure, and the large gear is connected with the handle, and the small gear is connected with the screwdriver rod. The screwdriver can reduce the times for rotating the handle, thereby having high working efficiency.
Description
Technical field
The utility model relates to the screwdriver of a kind of knife bar than the fast several times of handle rotary speed.
Background technology
At present, general screwdriver is made of handle and knife bar, and knife bar speed is identical with handle speed, need rotate a lot of circles when therefore loading and unloading screw, time-consuming effort again.
Summary of the invention
In order to overcome the existing slow deficiency of screwdriver rotary speed, the utility model provides a kind of fast rotary screw cutter, and this screwdriver can realize that the knife bar rotary speed is the several times of handle rotary speed.
The technical scheme that its technical problem that solves the utility model adopts is: handle is fixedlyed connected with a gear wheel, and knife bar is fixedlyed connected with a pinion.Because during two gears engaged, the ratio of the rotating speed of pinion and gear wheel equals the ratio of the gear wheel and the pinion number of teeth, therefore when the gear wheel that is connected with handle directly meshes with the pinion that is connected with knife bar, knife bar speed will be N times of handle speed, the N=gear wheel number of teeth/pinion number of teeth.Also can increase the gear pair transmission therebetween, increase their transmission speed ratio, reach the purpose of high speed transmission.
The beneficial effects of the utility model are: reduce the manual number of turns, handled easily saves time, and is laborsaving.
Description of drawings
Fig. 1 is the utility model overall structure schematic diagram.
Below in conjunction with drawings and Examples the utility model is further specified.
In the accompanying drawing 1: 1 is handle, and 2 is housing, and 3 is jackshaft, and 4 is knife bar, and 5 is driving shaft.(housing is two parts, and the first half is not drawn)
Annotate: 3,4,5 all is gear shaft.
The specific embodiment
5 bottom is contained on the handle, the pinion of 5 gear wheel and jackshaft 3, the pinion of the gear wheel of jackshaft 3 and knife bar 4.All gears all are contained in 2 the cavity.During people's turning handle 1,1 drives 5 rotates, and 5 drive 3,3 drives 4, thereby knife bar rotates in the same way with handle and knife bar than handle fast a lot of times.During the loading and unloading screw, a hand rest is lived housing 2, and another holds handle, so just can work easily.
Claims (1)
- A kind of knife bar is than the screwdriver of the fast several times of handle rotary speed, in housing, and the gear pair transmission, it is characterized in that: gear wheel is a driving wheel, and pinion is a driven pulley, and large and small gear is external toothing, two gears are parallel axes structures, and what link to each other with handle is gear wheel, and what link to each other with knife bar is pinion.
