Description

A kind of efficiently triangular knife Firewood cutter

Technical field

The present invention relates to firewood splitting tool, the firewood splitting tool needed for especially indivedual dining rooms and rural households --- it is a kind of efficient Triangular knife Firewood cutter.

Background technology

The firewood splitting tool of indivedual dining rooms and rural households is exactly to use the axe cut firewood at present, and sectional firewood is carried out Hack.However, because the axe that firewood is upright unstable, hacks is firmly inaccurate, axe usually occur, to hack firewood efficiency low, even The accident hurted sb.'s feelings occurs.

The content of the invention

Instant invention overcomes firewood is hacked with the axe cut firewood, the upright axe that is unstable, hacking of firewood of appearance is exerted oneself not It is accurate, hack the drawbacks of firewood efficiency is low, even hurts sb.'s feelings accident.A kind of efficiently triangular knife Firewood cutter can make firewood stand firm, with hammer Son can firewood, and hack firewood efficiency high, the accident that will not be hurted sb.'s feelings.

In order to solve the above technical problems, the technical solution adopted in the present invention is as follows：It is a kind of efficiently triangular knife Firewood cutter by Concave curve knife 1, spring groove 2, concave curve tool rest 3, U-shaped spring 4 form.

The beneficial effects of the invention are as follows：A kind of efficiently triangular knife Firewood cutter, first, stablizing during firewood can be made poly-, second, not The accident that can hurt sb.'s feelings and safety, third, with hammer can firewood dare firmly and effect is good, efficiency high, fourth, the U-shaped of U-shaped spring Make the firewood of bending complicated shape can place.

Brief description of the drawings

Fig. 1 is a kind of schematic diagram of efficiently triangular knife Firewood cutter；Fig. 2 is the schematic diagram that straight firewood is placed；Fig. 3 is bending The schematic diagram that firewood is placed；Fig. 4 is the transverse sectional view of concave curve knife 1；Fig. 5 is a kind of vertical view of efficiently triangular knife Firewood cutter Figure；Fig. 6 is the schematic diagram of concave curve knife 1 and concave curve tool rest 3.

Embodiment

It is first according to make shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, three concave curves is made with Fine Steel Casting iron Knife 1, with cast steel casting concave curve tool rest 3, U-shaped spring 4 is made with carbon spring steel wires, the U-shaped mouth of U-shaped spring 4 is opened to the right.

Then, assembled according to shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, it is first, structure identical three is recessed Shape curve knife 1 is mutually 120o angles, and three concave curve knives 1 are fixedly connected with concave curve tool rest 3, and three concave curve knives 1 are solid Surely it is connected on the central shaft of concave curve tool rest 3, three concave curve knives 1 are flexibly connected with U-shaped spring 4, and spring groove 2 is opened in The blade of each concave curve knife 1.

A kind of operation principle of efficiently triangular knife Firewood cutter.The blade of concave curve knife 1 is concave curve shape, first, recessed Stablize during the concave curve shape of shape curve knife 1 can make firewood poly-, the blade contact area of firewood and concave curve knife 1 is small, energy Larger pressure is obtained, firewood is easily rived；Second, spring groove 2 is accurately positioned U-shaped spring 4, U-shaped spring 4 makes firewood It can stablize, its right openings can place variously-shaped firewood；Third, when firewood is pounded downwards by hammer, U-shaped spring 4 can To be compressed, protect the blade of concave curve knife 1 not hit by hammer；Fourth, concave curve tool rest 3 can be placed on weak soil face On, and firewood effect is constant.

A kind of course of work of efficiently triangular knife Firewood cutter.First, by variously-shaped firewood hacksaw different in size The short firewood to cut off to length；Then, U-shaped spring 4 is put into the spring groove 2 of concave curve knife 1, then by straight firewood 5 Put U-shaped spring 4 into；Finally with above hammer firewood, then the blade below firewood with concave curve knife 1 mutually hits, Firewood will cleave into three pieces by concave curve knife 1.Firewood 6 will be bent and put a kind of U-shaped spring 4 of efficiently triangular knife Firewood cutter into In, the U-shaped of U-shaped spring 4 allows the firewood of bending to be placed on the inside.Then with above hammer firewood, then firewood with it is recessed The blade of shape curve knife 1 mutually hits, and firewood will cleave into three pieces by concave curve knife 1.
