Abstract
The utility model relates to a production tool, and particularly relates to a pedaling type drill bit. The pedaling type drill bit is characterized in that a gearwheel is engaged with a pinion, wherein the gearwheel is arranged on a rotating shaft, and two ends of the rotating shaft are arranged on a bearing which supports a main housing; pedaling rods connected with pedals are also arranged at two ends of the rotating shaft; an output shaft of the pinion is connected with a flexible shaft through a connector, and the other end of the flexible shaft is connected on a central shaft arranged in a handle housing; the central shaft is arranged on the bearing in the handle housing, and the other end of the central shaft is provided with a spiral sleeve for fixing a drill; and a handle is also connected with the handle housing. According to the pedaling type drill bit, the pedals are connected with the pedaling rods, and thus the gearwheel is driven to rotate; the gearwheel is engaged with the pinion, and the pinion is connected with the central shaft via the flexible shaft, so that the pedals can freely rotate in a positive direction or a negative direction through the gearwheel, and furthermore, the drill can rotate in the positive direction or the negative direction via the central shaft.
Description
Technical field
The utility model relates to a kind of tool of production, relates to a kind of foot-operated drill bit.
Background technology
As everyone knows, Electric drill-bit is one of instrument that often uses during people work, work.But, can not use in the place that non-transformer or power line can't touch, cause influencing some operate as normal.
Summary of the invention
For solving the problems of the technologies described above, this is novel to provide a kind of foot-operated drill bit.
This novel following solution of taking is:
A kind of foot-operated drill bit, mainly by under-chassis, gear wheel, pinion, main casing, treadle, flexible axle, handgrip housing, axle core, screw-casing, bearing, drill bit for constituting, it is characterized in that: gear wheel is meshed with pinion; Gear wheel is arranged in the rotating shaft, and the rotating shaft two ends are erected on the bearing of main casing support, and treadle is also installed at the rotating shaft two ends; Treadle connects foot-operated, and the output shaft of pinion is connected with flexible axle through joint, and the flexible axle other end is connected on the built-in axle core of handgrip housing; The axle core is placed on the bearing, and bearing is positioned in the handgrip housing, and the other end of axle core is to settle screw-casing; The screw-casing fixed drill bit also connects place's handle on the handgrip housing.
Through above-mentioned, the foot-operated treadle that connects, and drive the gear wheel rotation, gear wheel is nibbled body mutually with pinion, and pinion is connected with an axle core through flexible axle, and foot-operated can to do the both forward and reverse directions rotation at gear wheel free, further core both forward and reverse directions rotary drilling-head.
Compared with prior art, the beneficial effect of the utility model is: rational in infrastructure, convenient and practical, safe and reliable, control easyly, time saving and energy saving, raise labour efficiency.
Description of drawings
Fig. 1 is this novel foot-operated drill main body structure chart.
Indicate among the figure: the 1-under-chassis, the 2-gear wheel, the 3-pinion, the 4-main casing, the 5-treadle, 6-is foot-operated, 7-joint, 8-flexible axle, 9-handgrip housing, 10-axle core, 11-screw-casing, 12-bearing, 13-drill bit, 14-handle.
The specific embodiment
Further specify below in conjunction with accompanying drawing.
In Fig. 1, a kind of foot-operated drill bit, mainly by under-chassis 1, gear wheel 2, pinion 3, main casing 4, treadle 5, flexible axle 8, handgrip housing 9, axle core 10, screw-casing 11, bearing 12, drill bit 13 for constituting; It is characterized in that: gear wheel 2 is meshed with pinion 3, and gear wheel 2 is arranged in the rotating shaft, and the rotating shaft two ends are erected on the bearing of main casing 4 supports; Treadle 5 is also installed at the rotating shaft two ends, and treadle 5 connects rides 6, and the output shaft of pinion 3 is connected with flexible axle 8 through joint 7; Flexible axle 8 other ends are connected on the built-in axle core 10 of handgrip housing 9; Axle core 10 is placed on the bearing 12, and bearing 12 is positioned in the handgrip housing 9, and the other end of axle core 10 is to settle screw-casing 11; Screw-casing 11 fixed drill bit 13 also connect place's handle 14 on the handgrip housing 9.
Through above-mentioned, foot-operated 6 connect treadle 5, and drive gear wheel 2 rotations; Gear wheel 2 is nibbled body mutually with pinion 3; Pinion 3 is connected with axle core 10 through flexible axle 8, and foot-operated 6 can do both forward and reverse directions rotation freedom, further axle core 10 both forward and reverse directions rotary drilling-heads 13 at gear wheel 2.
Certainly; Above-mentioned practical implementation is not to be to this novel restriction, and those of ordinary skill also can be made some variations, improvement, interpolation or alternative in this novel essential scope; All technical schemes that mapping mode obtains that adopts the equivalence replacement or be equal to all drop in this novel protection domain.
