Description

A kind of glue cutter of changeable blade

Technical field

The utility model relates to a kind of glue cutter of changeable blade of rubber plantation rubber tapping usefulness.

Background technology

More than one since century, the employed glue cutter of rubber plantation rubber tapping employee still is traditional triangular chisel so far, operating personnel's workload is big, with China's two versions in west is example, each rubber tapping employee will finish the rubber tapping amount of 500 gums every day, finish so heavy production task, the rubber tapping instrument plays an important role in process of production, also particularly seems important.Before the utility model, the rubber tapping employee for the blade of using blunt because of grinding on-site, the glue cutter that can only more renew.According to statistics, each rubber tapping employee must be with 2～3 every day fully the glue cutter, both brings very big inconvenience to work, has increased production cost again.

Summary of the invention

Task to be solved in the utility model provides a kind of glue cutter of changeable blade, and it has fundamentally changed the performance of traditional glue cutter, has saved production cost, has accelerated the rubber tapping process.

For finishing above-mentioned task, the technical solution adopted in the utility model is: the glue cutter of described a kind of changeable blade comprises blade, knife rest and handle of a knife, its intermediate slide and handle of a knife are same as the prior art, its structure or shape are not done too big change, described blade is made of steel alloy, launches the back and becomes baby's trousers shape, and its section is sharp triangle, handle of a knife is used the handle of a knife of colloid instead, and their threes can pull down mutually is convenient to packing.A head cavity that is assemblied in handle of a knife of knife rest, the other end of knife rest interlocks mutually with blade, and described mode or the structure of interlocking has fitted outside to interlock with interpolation type to interlock.The knife edge is arranged at the top of blade, the lower end symmetry of blade is manufactured with left tool rest and right tool rest, inwall at left tool rest or right tool rest, outer wall at left tool rest or right tool rest has lock cutter bank in addition, and escape is arranged in the lower end of left tool rest or right tool rest, perhaps have the lock tool bore on the knife rest wall, there is the balance bank inwall lower end of blade.

Adopt the glue cutter of a kind of changeable blade that as above technical scheme provides to compare with the triangular chisel sheet of present use, beneficial effect is:

1. knife rest long service life, the operating period can reach 10 years;

2. can change blade at any time, blade is blunt need not change the glue cutter, only needs to change blade and gets final product;

3. save cost, can disposablely use, also reusable, repeated use can reach about 100 times;

4. easy to carry, save workload.

Embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.

Embodiment 1: shown in Fig. 1,2,3,4.

A head cavity that is assemblied in handle of a knife 3 one ends of knife rest 2, this assembly structure or pattern are identical with prior art, and the other end of knife rest 2 interlocks mutually with blade 1, and the section configuration of the described blade 1 of present embodiment is the acute angle shape structural shape.The upper end of blade 1 have the knife edge 1 ', the lower end symmetry of blade 1 is manufactured with right tool rest 1A and left tool rest 1B, is manufactured with lock cutter bank 5 at the inwall of left tool rest 1B, described lock cutter bank 5 also can be produced on the inwall of right tool rest 1A.When being inserted on the knife rest 2, blade 1 make lock cutter bank 5 be close to the outer wall of knife rest 2, in the lower end of left tool rest 1B escape 6 is arranged, when needs take off blade 1, operating personnel insert in the escape 6 with startup instrument (as screw driver etc.) and lever up left tool rest 1B, make lock cutter bank 5 leave the outer wall of knife rest 2 slightly, blade 1 is taken off get final product.There is weighing apparatus bank 1C the lower end of blade 1 inwall, and balance bank 1C is located in the top of knife rest 2, and the effect of balance bank 1C is stablize the relative position of blade 1 and knife rest 2, and the rubber juice cut off is not flow to the cutter groove of knife rest 2 from the cutter groove of blade 1 with not stopped.When changing blade 1, knife rest 2 and handle of a knife 3 are reusable.

Embodiment 2 is shown in Fig. 1,5,6.

The described blade 1 of present embodiment is interpolation type blade 1 (shown in Fig. 5,6), a head cavity that is assemblied in handle of a knife 3 of knife rest 2, the other end of knife rest 2 interlocks mutually with blade 1, the section configuration of blade 1 is the acute angle shape structural shape, the upper end of blade 1 have the knife edge 1 ', the lower end symmetry of blade 1 is manufactured with right tool rest 1A and left tool rest 1B, outer wall at left tool rest 1B has lock cutter bank 5, described lock cutter bank 5 also can be produced on the outer wall of right tool rest 1A, and the lock tool bore 4 that has on knife rest 2 gets close to the lower end of blade 1.Blade 1 interpolation type makes lock cutter bank 5 be close to the inwall of knife rest 2 when being inserted on the knife rest 2, when needs take off blade 1, operating personnel take off blade 1 from the inwall that backs down left tool rest 1B after lock tool bore 4 inserts and make it leave knife rest 2 with startup instrument (as screw driver etc.) and get final product, the inwall of blade 1 also has balance bank 1C, but goes downstream as the weighing apparatus bank 1C of glue juice Shunping County of cutting off.When blade 1 rust, can take off blade 1 at any time, and knife rest 2 and handle of a knife 3 are reusable.
