Abstract
A drill comprises a cross rod and a vertical rod; the vertical rod penetrates through a through hole in the middle of the cross rod so as to be capable of rotating in the cross rod; the top end of the vertical rod is connected with the two ends of the cross rod through ropes; a drill bit is arranged at the bottom end of the vertical rod. After the structure is adopted, the cross rod is moved to the upper part of the vertical rod, and the cross rod is rotated to ensure that the ropes can be wound on the vertical rod; after the drill bit is aligned with a part where drilling is required, and a downward pressure is applied to the cross rod; as the cross rod moves to the lower part of the vertical rod, a horizontal pulling force is applied to the vertical rod by the ropes, so that the vertical rod can rotate to drive the drill bit to drill.
Description
Technical field
The utility model relates to a kind of drill, is specifically related to a kind of manually operated drill.
Background technology
Existing drill mainly drives electric drill to hole by motor, this drill must use having electric in the situation that, and complex structure, and manufacturing cost is relatively high, therefore not only there is the problem that is subject to power limitations of using in it, but also exist, uses and the high problem of manufacturing cost.
Summary of the invention
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, and a kind of easy drill providing, and it only needs the shirtsleeve operation step just can be manually and well complete boring.
The purpose of this utility model is achieved in that
A drill, it comprises cross bar and montant, and montant can rotate montant through the through hole at cross bar middle part in cross bar, and the top of montant is connected by rope with cross bar two ends, and the bottom of montant is provided with drill bit.
Above-mentioned montant bottom is provided with slot, and the cross section of slot is rectangle, is provided with magnet in slot, and drill bit is by being made by the metal of attraction.
Above-mentioned cross bar two ends are provided with handle, and handle is long straight-bar body.
The utility model has been obtained following technique effect:
Adopt said structure, cross bar is moved to the upper part of montant, rotary bar makes rope can be wrapped on montant, drill bit is being aimed at behind the position that needs boring, cross bar is applied to downward pressure, along with cross bar is mobile to montant below, rope can be given the pulling force of a horizontal direction of montant, montant is rotated and drive bit bore;
Adopt montant bottom to be provided with slot, the cross section of slot is the structure of rectangle, drill bit can well be limited in slot, can guarantee the rotation that drill bit is stable like this, adopt in slot and be provided with magnet, drill bit is by can, by the metal structure of attraction, making like this drill bit can not drop out from slot at gravity;
Adopt cross bar two ends to be provided with handle, the structure that handle is long straight-bar body, energy person's easy to use gripping, person easy to use exerts pressure to cross bar.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 and Fig. 2 are structural representation of the present utility model.
The specific embodiment
A drill as shown in Figure 1, it comprises cross bar 1 and montant 2, and montant 2 can rotate montant through the through hole at cross bar 1 middle part in cross bar, and the top of montant 1 is connected 3 with cross bar 1 two ends by rope, and the bottom of montant 2 is provided with drill bit 4.
Described montant 2 bottoms are provided with slot 6, and the cross section of slot is rectangle, is provided with magnet in slot, and drill bit 4, by being made by the metal of attraction, can be comprised by the metal of attraction the metals such as iron, cobalt, nickel.
Described cross bar 1 two ends are provided with handle 5, and handle 5 is long straight-bar body.
Adopt said structure, cross bar is moved to the upper part of montant, rotary bar makes rope can be wrapped on montant, drill bit is being aimed at behind the position that needs boring, cross bar is applied to downward pressure, along with cross bar is mobile to montant below, rope can be given the pulling force of a horizontal direction of montant, montant is rotated and drive bit bore; Adopt montant bottom to be provided with slot, the cross section of slot is the structure of rectangle, drill bit can well be limited in slot, can guarantee the rotation that drill bit is stable like this, adopt in slot and be provided with magnet, drill bit is by can, by the metal structure of attraction, making like this drill bit can not drop out from slot at gravity; Adopt cross bar two ends to be provided with handle, the structure that handle is long straight-bar body, energy person's easy to use gripping, person easy to use exerts pressure to cross bar.
