Description
Technical field
The utility model is related to tool equipment field, and in particular to a kind of stable operation handsaw.
Background technology
Hand saws, because it lightly flexibly, is fast used, is a common instrument, becomes people house instrument and factory
Industry tools.Hand saws includes support, lever and saw blade, and common structure such as publication No. is special for the China of the A of CN 103878438
Structure disclosed in sharp file, saw blade treats processing object in the presence of people's thrust and carries out sawization cutting.For another example notification number is
A kind of back detachable hand saw that the Chinese patent document of 100546746C is announced, for saw blade and operation connected mode simultaneously is carried out
Optimization so that the dismounting and fastening of saw blade become more convenient.
But such structure still has certain deficiency, the use of handsaw fully relies on manpower cutting, with putting forth effort
Exhaust, the action of cutting has deformation, and the track for pushing away saw has deviation, on the one hand, the section of cutting has not neat situation and goes out
It is existing, on the other hand, it may appear that the situation that oarsman even slips out of the hand, cause potential safety hazard.
Utility model content
The purpose of this utility model is to provide a kind of stable operation handsaw, high with workman's hand laminating degree, and enhancing is pushed away sawed
The stability of saw blade motion track in journey, lifts safety coefficient.
Above-mentioned technical purpose of the present utility model technical scheme is that：A kind of stable operation hand
Saw, comprising saw frame, the saw blade on saw frame and the lever being connected with the saw frame, the lever includes what is be connected with saw frame
Connecting portion and the connecting portion connect, into curve, and the back of the hand contact part for contradicting with operator's the back of the hand and with described the back of the hand
The upper stopper of contact part connection, the upper stopper away from the back of the hand contact part direction by gradually inclining upward；Described the back of the hand
Contact part is provided with the steady back piece for fixing the back of the hand, the upper stopper be provided with for into gap between finger so as to increase hand
Refer to the crack piece of stability.
The saw blade is arranged on the saw frame, for cutting object.The hand-held lever of user is operated, the company
Socket part and the saw blade connect, and the connecting portion is connected with the saw frame, and into curve, fit user for the back of the hand contact part
The back of the hand position, and the upper stopper then clasps four fingers of user, increases stability.
Further, the back of the hand contact part is provided with the steady back piece, at the steady back piece increase and user's the back of the hand
Friction anti-skid factor, increases the stability of the back of the hand, so as to increase polarization of the whole handsaw in saw action is pushed away.Further
, the crack piece could be arranged to multiple in actual production, and such as three, four fingers have three cracks, the folder
Patch is put into these three finger cracks, is clamped for finger, further increases skid resistance.
It is very big to the physical fitness requirement of user during handsaw cuts different from common manual labor, and here is basic
On, user still will hold handsaw using a part of strength, which further adds physical demands.And work as and be short of physical strength
When, the unstable phenomenon of hand shaking or positioning not only occurs, uneven and damaged products the situation in saw face just occurs, it is more dangerous
It is that if slipping out of the hand, sawtooth can hurt oneself, with certain potential safety hazard.So the major design of the technical program is to increase
