It is fixed in the centre bore of outer shaft, accumulation of energy sphere is fixed in fixed ring by connecting rod, and fixed ring is fixed on outer shaft, is drawn
Power spring one end is fixed on one end on connecting rod close to accumulation of energy sphere, and the tension spring other end is fixed on slip ring, slip ring
It is set on outer shaft, cutter head is fixed on default shaft end portion.
Working principle:
The present invention is completed to store power by pressing knife handle, pressed in use, by cutter head pressing on screw or screw
During storing power, inner slide is moved inside knife handle to bottom cover direction by helix, and linear motion is converted to rotation by inner slide
Transhipment is dynamic, drives the accumulation of energy sphere on outer shaft and outer shaft to rotate jointly by the one-directional rotation teeth of inner slide, due to
The supporting role of knife handle inner spring, the bracket on bottom cover, friction block also follow sliding block to rotate together with.In friction block close to knife handle bottom
When lid position, pressing force can reduce, inner slide is returned into knife handle top cover position by the active force of spring, at this time due to interior
The one-directional rotation teeth of sliding block and the teeth on flange are detached from, and will not influence the movement of outer shaft.Knife handle top cover is reached in sliding block
Behind position, knife handle can be pressed again, continue to store power, storage power and so on can be completed.Since rotation momentum is gradually increased, store
Energy ball gradually opens (referring to Fig. 6), and the size of rotation momentum can be measured according to the size that Energy storage ball opens.
After completing to store power, continue to press knife handle, the front end wedge-shaped part of friction block allowed to be inserted between interior dead axle and outer shaft,
Interior dead axle and outer shaft locking are integrated, so that the movement of outer shaft is passed to interior dead axle, and screw is driven to move, is completed
It is screwed into or back-outs process.During being screwed into or back-outing, with the rotation of outer shaft, Energy storage ball and rotary inertia is passed to
Outer shaft completes the release of energy, and accumulation of energy, which is asked, to be started to shrink, until the energy of Energy storage ball is not enough to driving.
After use, by manually extracting cutter hub from inside to outside from knife handle out, friction block is made to be detached from interior dead axle and outer shaft.
Embodiment described above only describe the preferred embodiments of the invention, not to model of the invention
It encloses and is defined, without departing from the spirit of the design of the present invention, those of ordinary skill in the art are to technical side of the invention
The various changes and improvements that case is made should all be fallen into the protection scope that the claims in the present invention determine.
