Description

A kind of nut cracker

technical field

The utility model relates to a device for crushing shells of nuts, which belongs to daily use tools.

Background technique

In the prior art, the known cracker for cracking nuts is composed of two halves of bow-shaped pliers with the shape of clamping nuts connected by a pin shaft, and the two halves of the pliers can rotate freely around the pin shaft, and the two halves of the pliers are opened to Nuts are put into the bow-shaped body, and the nuts are crushed when the forceps are closed. When this kind of forceps is used, the dried fruit shell and the pulp are often crushed together due to excessive force. Another tool is called aluminum-plastic pipe scissors, which are mainly used to cut aluminum-plastic pipes, and can also cut dried fruits. Its structure includes left and right scissors. There is a shaft pin hole in the middle part of the cutting blade body, the upper part is the cutting blade, and the lower part is the ratchet wheel. The cutting blade body and the ratchet wheel are integrated. The left scissor connects the activities. The upper part of the right scissors handle is a double-layer sheet-shaped pressing jaw with a gap in the middle. The ratchet on the cutting blade body meshes with the pawl installed on the left scissors handle. Press the jaws together and cut off the aluminum-plastic tube. Separate the left and right scissors handles by hand, the pawls are separated from the ratchet, then the jaws and the cutting blades are separated, and the left and right scissors handles are closed again to continue cutting. The opening angle of the left and right scissors can be controlled by yourself, which is convenient for applying force and obtaining greater closing force. According to the opening angle of the cutting edge and the pressing jaw, the scissors can be closed once or multiple times. But the aluminum-plastic pipe shear of this structure only has the function of cutting off the nut shell and pulp, and is inconvenient for simply breaking the nut shell.

Contents of the invention

The purpose of the utility model is to provide a kind of cracker for cracking nut shells, which has a simple structure and stable force application, which overcomes the deficiencies of the prior art.

The technical scheme adopted in the utility model is as follows: a kind of cracker for cracking nuts, improved by aluminum-plastic pipe shears, comprising left scissors and right scissors, the left scissors are movably connected with the right scissors through pin shafts, and the cutting blade body The middle part is movably connected with the right scissors handle through a pin shaft, the ratchet wheel at the lower part of the scissors body engages with the pawl fixed on the left scissors handle, and the lower end of the scissors body is movably connected with the left scissors handle through a comparison rod. The upper part of the right scissor handle is a double-layer sheet-shaped pressing jaw with a gap in the middle. The upper part of the cutting blade body is fastened with a double-layer sheet-shaped increasing jaw. The inner side of the increasing jaw is bow-shaped and serrated. The upper part of the right scissor handle is double-layered to press the gap in the middle of the jaws. The enlarged jaw can easily enter and exit the gap in the middle of the pressure jaw. The arc shape that fits together, like this, when the increasing jaw and the pressing jaw are closed, the nut just in time is clamped.

Set the enlarged jaws on both sides of the upper part of the cutting blade body, and fix them with screws and nuts to the cutting blade body, which is convenient for disassembly and assembly, and realizes a multi-purpose pliers. Function.

Its use method is as follows: put nuts such as walnuts, pine nuts, etc. between the double-layer sheet-shaped increasing jaws, tighten the left and right scissors, and the ratchet pushes the ratchet, so that the pressing jaws and increasing jaws are close to each other for clamping Catch the nuts, using force until the shells of the nuts are broken.

The beneficial effects of the utility model are: compared with common nut crushing pliers, it is convenient to apply force, and the jaws are closed and crushed slowly and stably, which is convenient for protecting the pulp from being pinched. When cutting is required, the original scissor function can be restored by removing the extended jaw, realizing multiple functions of one pliers.

Detailed ways

Below in conjunction with accompanying drawing and example the utility model is described further.

Referring to Fig. 1 and Fig. 2, a kind of nut cracker has a left scissor handle 10 and a right scissor handle 9, the left scissor handle is movably connected with the right scissor handle through a pin shaft, and the middle part of the scissor body 5 passes through the right scissor handle 9 The pin shaft 6 is movably connected, the ratchet 8 in the middle of the scissor body is engaged with the pawl 7 fixed on the left scissor handle 10, the lower end of the scissor body 5 is movably connected with the left scissor handle 10 through a hinge rod, and the double-layer sheet-like The jaw 2 is bent from a steel sheet, the inner side is bow-shaped and has serrations. It is fastened and fitted on both sides of the upper part of the cutting blade body 5 by two pairs of screws 3 and nuts 4 and wrapped around the cutting edge. The upper part of the right scissors handle The inner side of the double-layer sheet pressing jaw 1 is an arc suitable for the clamping of the double-layer sheet-like increasing jaw 2 clamped on both sides of the cutting edge body 5 top, and when the increasing jaw and the pressing jaw are closed, just Hold the nuts. Put nuts (such as walnuts, pine nuts) between the double-layer sheet-shaped increasing jaws 2, close the left and right scissors, and the ratchet 7 pushes the ratchet 8 to make the lamination jaw 1 and the increasing jaw 2 approach until the

Nut shells are broken.
