For above-mentioned prior art Problems existing, the utility model object is to provide a kind of hand to bore, and when using, rotating speed is fast, lowering energy-saving.The technical solution of the utility model is: hand bores, comprise handle 1, inner core 3, urceolus 4 and screw mandrel 6, described handle 1 comprises and is connected cylinder 2, and described inner core 3 comprises pressure cylinder 5 and pin 9, described urceolus 4 comprises anti-slip cap 10, and described screw mandrel 6 comprises solid brill cap 7 and drill bit 8.In the hypomere of described handle 1, rank is connected the epimere of cylinder 2, and the hypomere loins internal fixtion center bore being connected cylinder 2 is about greater than the annulus that bar external diameter followed closely by pin 9.Described inner core 3 is inserted in urceolus 4, and inner core 3 outer wall and urceolus 4 inwall are fitted, and inner core 3 end peristoma is connected with peristoma on pressure cylinder 5, and the nail bar lower end of pin 9 is connected with the upper end of inner core 3 from being connected cylinder 2 insertion suitable for reading through the circle ring center hole be connected in cylinder 2.Screw on anti-slip cap 10 in the upper end of described urceolus 4, internal thread and the outer silk of urceolus 4 of anti-slip cap 10 match, and the upper peristoma internal diameter of anti-slip cap 10 equals the external diameter of inner core 3, and the lower aperture centre of urceolus 4 arranges the hole that screw mandrel 6 end section can pass.Described screw mandrel 6 is set to the larger trapezoidal single thread bar of thread form of the parameter lift angle consistent with pressure cylinder 5 internal thread, the epimere of screw mandrel 6 is placed in inner core 3, the upper end of screw mandrel 6 is screwed into the diameter nut consistent with inner core 3 internal diameter, the lower end of screw mandrel 6 is connected with the upper end of the cross cut inner core admittedly boring cap 7 through urceolus 4 bottom center hole, the epimere of drill bit 8 is placed in after in cross cut, tightens solid brill cap 7.The beneficial effects of the utility model are: when people need when electricity consumption inconvenience to hole, rotating speed is very fast, easy to carry, lowering energy-saving.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model hand bores.In figure: 1 is handle; 2 for being connected cylinder; 3 is inner core; 4 is urceolus; 5 is pressure cylinder; 6 is screw mandrel; 7 for admittedly to bore cap; 8 is drill bit; 9 is pin; 10 is anti-slip cap.
Detailed description of the invention
As shown in Figure 1, hand bores, and comprises handle 1, inner core 3, urceolus 4 and screw mandrel 6, and described handle 1 comprises and is connected cylinder 2, and described inner core 3 comprises pressure cylinder 5 and pin 9, and described urceolus 4 comprises anti-slip cap 10, and described screw mandrel 6 comprises solid brill cap 7 and drill bit 8, the lower end outer surface of described handle 1 arranges a cranse, and in the hypomere of handle 1, rank is connected the epimere of cylinder 2, and the hypomere loins internal fixtion center bore being connected cylinder 2 is about greater than the annulus that bar external diameter followed closely by pin 9, described inner core 3 is inserted in urceolus 4, the external diameter of inner core 3 is about less than the internal diameter that upper end is screwed with the urceolus 4 of anti-slip cap 10, inner core 3 outer wall and urceolus 4 inwall are fitted, inner core 3 end peristoma is connected with peristoma on pressure cylinder 5, and the nail bar lower end of pin 9 is connected with the upper end of inner core 3 from being connected cylinder 2 insertion suitable for reading through the circle ring center hole be connected in cylinder 2, screw on anti-slip cap 10 in the upper end of described urceolus 4, internal thread and the outer silk of urceolus 4 of anti-slip cap 10 match, the upper peristoma internal diameter of anti-slip cap 10 equals the external diameter of inner core 3, in case the upper peristoma of inner core 3 hypostome and pressure cylinder 5 departs from when pulling force is excessive, the lower aperture centre of urceolus 4 arranges the hole that screw mandrel 6 end section can pass, the internal thread of described screw mandrel 6 external screw thread and pressure cylinder 5 matches, screw mandrel 6 is set to the larger trapezoidal single thread bar of thread form of the parameter lift angle consistent with pressure cylinder 5 internal thread, the epimere of screw mandrel 6 is placed in inner core 3, the upper end of screw mandrel 6 is screwed into the diameter nut consistent with inner core 3 internal diameter, in case when pulling force is excessive, pressure cylinder 5 and screw mandrel 6 depart from, the lower end of screw mandrel 6 is connected with the upper end of the cross cut inner core admittedly boring cap 7 through urceolus 4 bottom center hole, drill bit 8 is set to the drill bit of known multiple models, the epimere of drill bit 8 is placed in after in cross cut, tighten solid brill cap 7, with fixed drill bit 8, when holing, press down handle 1, the pressure cylinder 5 of inner core 3 lower end drives the drill bit 8 in the solid brill cap 7 cross cut of screw mandrel 6 lower end to rotate, when the lower end being connected cylinder 2 touches the upper peristoma of urceolus 4, upper handle handle 1, press down again second time, repeatedly carry out, until reach boring object, so hole, rotating speed is very fast, lowering energy-saving.
