Embodiment Construction

[0014] like figure 1 Shown a kind of drill, it comprises cross bar 1 and vertical bar 2, and vertical bar 2 passes through the through hole of cross bar 1 middle part so that vertical bar can rotate in cross bar, and the top of vertical bar 1 and cross bar 1 two The ends are connected 3 by a rope, and the bottom end of the vertical rod 2 is provided with a drill bit 4 .

[0015] Described vertical bar 2 bottoms are provided with slot 6, and the cross section of slot is rectangular, and magnet is arranged in slot, and drill bit 4 is made by the metal that can be attracted by magnet, and the metal that can be attracted by magnet comprises iron, Metals such as cobalt and nickel.

[0016] Both ends of the crossbar 1 are provided with handles 5, and the handles 5 are long straight rod bodies.

[0017] With the above structure, move the cross bar to the upper part of the vertical bar, rotate the cross bar so that the rope can be wound on the vertical bar, after aligning the drill ...

Abstract

A hole puncher comprises a transverse rod and a vertical rod; the vertical rod penetrates a through-hole at the middle part of the transverse rod so as to rotate in the transverse rod; the top end of the vertical rod is connected with two ends of the transverse rod by means of a rope; and a drill bit is arranged at the bottom end of the vertical rod. By adopting the above structure, the transverse rod is moved to the upper part of the vertical rod and is rotated to enable the rope to be twisted on the vertical rod; the drill bit aims at a position to be drilled, and a downward pressure is applied to the transverse rod; when the transverse rod moves to the lower side of the vertical rod, the rope brings a horizontal tension force to the vertical rod and the vertical rod is rotated to drive the drill bit to punch a hole.

Description

technical field [0001] The invention relates to a drill, in particular to a manually operated drill. Background technique [0002] Existing drills mainly rely on motor-driven electric drills to drill holes. This drill must be used with electricity, and has a complex structure and relatively high manufacturing costs. Therefore, it not only has the problem of being limited by the power supply , but also have the problem of high cost of use and manufacture. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a simple drill for the deficiencies of the above-mentioned prior art, which can manually and well complete the drilling with only simple operation steps. [0004] The purpose of the present invention is achieved like this: [0005] A drilling device, which includes a horizontal rod and a vertical rod, the vertical rod passes through the through hole in the middle of the horizontal rod so that the vertical rod can ...
