Abstract

The utility model relates to a hand-propelled tapping knife, which consists of a knife rest (2) provided with a handle (1) and a knife edge part, wherein the knife edge part is replaceable and consists of a V-shaped blade (5) at least one end of which is provided with a knife edge; and the V-shaped blade (5) is integrated with the knife rest (2) into a whole through muff coupling. The hand-propelled tapping knife does not take long time for milling, thereby saving the time, lightening the labor intensity, improving the production efficiency and the rubber yield, and being favorable for growth, healing and secondary cutting of a cut of a rubber tree.

Description

Hand-push type glue cutter

Technical field

The utility model relates to a kind of cutter, is specifically a kind ofly to get the hand-push type glue cutter that emulsus juice is used from bamboo grows.

Background technology

Bamboo grows mainly is grown in the torrid zone and subtropical zone, belongs to aiphyllium, and emulsus juice is arranged.Its emulsus juice has very strong elasticity and good insulation performance, plasticity after processing, water proof, gas barrier properties, and tension and characteristics such as wear-resisting apply to aspects such as industry, national defence, traffic, pharmaceutical sanitary field and daily life widely, and purposes is extremely wide.

Getting emulsus juice from bamboo grows at present is that usually said glue generally is to adopt the hand-push type rubber tapping knife, comprises handle, knife rest, and the knife rest front end has the edge of a knife, and the hand-push type rubber tapping knife all will could use with behind the sharpening stone mill every day.The edge of a knife approximate right angle shape of rubber tapping knife, the intersection point place is excessively slick and sly, and the both sides edge of a knife has tiny radian.During use, generally be that bark is severed from lower to upper by the following up spiral half cycle that is advanced into, glue is then collected with the glue cup toward dirty along scarfing.The edge of a knife can not injure the tree bar in progradation, and it is smooth smooth that scarfing will keep, otherwise injure tree bar place and can grow pimple, the rough smooth place of scarfing is also unfavorable to the bamboo grows growth, influence to open once more after the scarfing growth is healed and cut, therefore, the V-arrangement edge of a knife must be sharp, smooth, is convenient to bark and comes off.The sharpening process not only will consume the useless plenty of time, and very exquisite skill, the each sharpening, whetstone also will have polytype for using, and ground back all difficult specification requirement that reaches the glue cutter on sharpness on the radian on the straight line upper angle, even initial cutter sample grinds easily all and loses shape.Particularly when sharpness is not enough, easily increase frictional force, make the big reduction gum yield of the inaccessible oyster of bamboo grows latex.

Summary of the invention

The purpose of this utility model provide a kind of easy to use, need not spend the plenty of time and whet a knife, can improve greatly the hand-push type glue cutter of gum yield.

The hand-push type glue cutter that the utility model provides is grouped into by knife rest and the blade portion of being with handle, and the described edge of a knife partly is interchangeable, is made up of the V-knife sheet of the edge of a knife at least one end, and V-knife sheet and knife rest are connected as a single entity by socket.

V-knife sheet and knife rest are by engagement piece and keeper socket.

Described engagement piece is fixed on V-knife sheet both sides and bends inwards, and with the positive notch that forms of V-knife sheet, keeper is fixed on the knife rest both sides and cooperates the location with engagement piece.

All there is the edge of a knife at the two ends of V-knife sheet.

Hand-push type rubber tapping knife of the present utility model partly is interchangeable by the edge of a knife, be connected as a single entity by socket with knife rest, the V-knife sheet of edge of a knife part can be produced by batch by specification like this, during use, if the sharpness of edge of a knife part reduces, it can be taken out, change the other end or replace with another piece, avoid edge of a knife damage to delay work and mistake, do not require a great deal of time yet and whet a knife, can save time, reduce labor intensity, enhance productivity, because the specification requirement with required of edge of a knife part is consistent, particularly easily guarantee sharpness, can improve gum yield greatly, help bamboo grows scarfing growth healing and cut with opening once more.

Fig. 2 is the structure chart of V-knife sheet;

Fig. 3 is the structure chart of knife rest.

Embodiment

With reference to Fig. 1, Fig. 2, Fig. 3, the hand-push type glue cutter that the utility model provides, knife rest 2 and blade portion by band handle 1 are grouped into, and knife rest 2 is consistent with the shape of conventional rubber tapping knife, and the described edge of a knife partly is interchangeable, can from knife rest 2, take out easily and install, it all is made up of the V-knife sheet 5 of the edge of a knife two ends, and the rubber tapping knife blade portion of shape and routine is divided corresponding, i.e. cross section approximate right angle shape, the intersection point place is excessively slick and sly, and the both sides edge of a knife has tiny radian.V-knife sheet 5 and knife rest 2 are connected as a single entity by socket, socket place has engagement piece 4 and keeper 3, wherein engagement piece 4 is fixed on V-knife sheet 5 both sides and bends inwards, with the V-knife sheet 5 positive notches that form, keeper 3 is fixed on knife rest 2 both sides and cooperates the location with engagement piece 4, and the V-type notch in V-knife sheet 5 and knife rest 2 socket place fronts seamlessly transits, can keep V-knife sheet 5 fronts not have thing to hinder like this, bark is easily along the V-type landing of V-knife sheet during use, all there is the edge of a knife 6 at the two ends of this V-knife sheet 5, after the one end edge of a knife 6 is blunt, turns the other end and can use again.

Certainly, engagement piece 4 and keeper 3 in V-knife sheet 5 and knife rest 2 socket places also can adopt alternate manner, as long as convenient to remove, are convenient to the location during installation, do not hinder again during use and then can.
