Abstract
The utility model relates to fabric boring device technical field, especially a kind of low-resistance drill.It comprises base, drill body and drill bit, and drill bit is plugged in drill body, and floor installation is in the bottom of drill body, and drill bit is hollow tubular, and inside establish cylinder blade and section, cylinder blade is connected with bit by support.Cylinder blade and section are installed in the drill bit of hollow tubular, cylinder blade is rotatably connected in the bottom of drill bit by support, section is elastic sheet metal, upper end flushes with the inwall of drill bit, lower end is pressed on the medial surface of cylinder blade, during use, bit presses down, drive cylinder blade rotates, scroll-diced on fabric, and not only resistance is little, and tangent line flat smooth, the fragment cut is cut into slices from cylinder blade and is peeled off, and prevents from being bonded in impact on cylinder blade and runs, improve the stability of punching.
Description
Technical field
The utility model relates to fabric boring device technical field, especially a kind of low-resistance drill.
Background technology
At present, the drilling tool structure for the soft material of dry goods is simple, and during boring, due to the material characteristic of fabric, it is large that direct employing presses down the not only resistance that punches, and compare effort, and fabric forces stressed easy fold, cause out-of-flatness of holing.
Utility model content
Large in order to overcome existing fabric boring device perforate resistance, easily make fabric crease, irregular deficiency of holing, the utility model provides a kind of low-resistance drill.
The utility model solves the technical scheme that its technical problem adopts: a kind of low-resistance drill, comprise base, drill body and drill bit, drill bit is plugged in drill body, floor installation is in the bottom of drill body, drill bit is hollow tubular, inside establish cylinder blade and section, cylinder blade is connected with bit by support.
According to another embodiment of the present utility model, comprise the bottom that cylinder blade is evenly distributed on bit drills wall further.
According to another embodiment of the present utility model, comprise section further for elastic sheet metal, upper end is fixed on support, flushes with the inwall of drill bit.
According to another embodiment of the present utility model, the lower end comprising section is further pressed on the medial surface of cylinder blade.
The beneficial effects of the utility model are, cylinder blade and section are installed in the drill bit of hollow tubular, cylinder blade is rotatably connected in the bottom of drill bit by support, section is elastic sheet metal, upper end flushes with the inwall of drill bit, lower end is pressed on the medial surface of cylinder blade, during use, bit presses down, and drives cylinder blade to rotate, scroll-diced on fabric, not only resistance is little, and tangent line flat smooth, and the fragment cut is cut into slices from cylinder blade and peeled off, prevent from being bonded in impact on cylinder blade to run, improve the stability of punching.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. bases, 2. drill body, 3. drill bit, 4. cylinder blade in figure, 5. cut into slices, 6. support.
Detailed description of the invention
If Fig. 1 is structural representation of the present utility model, a kind of low-resistance drill, comprise base 1, drill body 2 and drill bit 3, drill bit 3 is plugged in drill body 2, base 1 is arranged on the bottom of drill body 2, drill bit 3 is hollow tubular, and inside establish cylinder blade 4 and section 5, cylinder blade 4 is rotatably connected with drill bit 3 by support 6.Cylinder blade 4 is evenly distributed on the bottom that drill bit 3 bores wall.Section 5 is elastic sheet metal, and upper end is fixing on the frame 6, flushes with the inwall of drill bit 3.The lower end of section 5 is pressed on the medial surface of cylinder blade 4.
Cylinder blade 4 and section 5 are installed in the drill bit 3 of hollow tubular, cylinder blade 4 is rotatably connected in the bottom of drill bit 3 by support 6, section 5 is elastic sheet metal, upper end flushes with the inwall of drill bit 3, lower end is pressed on the medial surface of cylinder blade 4, during use, drill bit 3 rotating down pressing, drive cylinder blade 4 to rotate, scroll-diced on fabric, not only resistance is little, and tangent line flat smooth, the fragment cut is cut into slices 5 from cylinder blade 4 stripping, prevents from being bonded in impact on cylinder blade 4 and runs, improve the stability of punching.
