Abstract
The invention discloses a manual power drill tool which is provided with a one-way overrunning clutch, wherein the one-way overrunning clutch is connected with a spindle; the spindle is installed in the lower end hole of a handle by a bearing; a lead screw and a screw are installed in a thread fit mode; the lower end of the lead screw is connected with the other end of the one-way overrunning clutch; one extruded end of the screw is clamped in a long slot a; the upper end of the lead screw is provided with a bearing installed on the upper end of the handle; a hole on the upper end of the handle is provided with a plug cover; a flywheel is installed on the position at lower end of the handle on the spindle; and a drilling chuck is installed on the tail end of the spindle.
Description
Technical field
The present invention relates to a kind of power drill instrument, particularly a kind of manual force drill tools belongs to the hardware ﹠ tools technical field.
Background technology
At present, the instrument that is used to hole is power-actuated form basically, though these power-actuated electric drills have laborsaving, operating efficiency advantage of higher, but, at some unregulated powers or from electric power place far away, can't use, refer in particular to field work installation and maintenance etc.
Summary of the invention
The objective of the invention is to: a kind of manual force drill tools is provided, the needs of adaptation in some unregulated power places and when field work, installation and maintenance, bring facility in the use to people, overcome in the unregulated power place or from electric power place far away and the defective of field work, installation, maintenance inconvenience.
The present invention realizes that the technical method that above-mentioned purpose adopts is: a kind of manual force drill tools, and it is to have a mono-directional overrun clutch by the manual force driller, and mono-directional overrun clutch one end is connected with rotating shaft, and rotating shaft is installed in the following stomidium of handle by bearing; Mode by threaded engagement between screw and the leading screw is installed together, the lower end of leading screw is connected with an other end of mono-directional overrun clutch, the outstanding end of screw is fastened among the elongated slot a, and the upper end of leading screw has a bearing to be installed in the upper end of handle, on the hole of handle upper end a blanking cover is arranged; Flywheel is installed in the lower end position that rotating shaft is in handle, and drill chuck is installed in the end of rotating shaft.
Operation principle of the present invention is: because screw thread is that a pitch is bigger between screw and the leading screw, the matching relationship that does not have self-locking each other, so, when handgrip be held in the outstanding end of screw, when spurring screw up and down, leading screw rotates back and forth with regard to positive and negative, but, owing between leading screw and rotating shaft, mono-directional overrun clutch has been installed, so, rotating shaft is just only by single direction rotation, flywheel stores unnecessary energy, so that when boring evenly discharges and guarantee normally carrying out of boring when bigger load.
Beneficial effect: a kind of manual force drill tools of the present invention, owing to do not rely on electric power energy, so, adaptation is at the needs of some unregulated power places and field work installation, maintenance, bring facility in the use to people, overcome in the unregulated power place or from electric power place far away and the defective of field work, installation, maintenance inconvenience.
