Abstract

The invention applies the wedge reinforcement and leverage principles to achieve the labor-saving purpose of a handheld clamp and to take the effect of saving 50-75 percent of labor, and provides a nutcracker which is very simple in structure and very convenient to use. The nutcracker consists of a handle I, a handle II, a lock pin and a torsion spring, wherein the handle I and the handle II, which are provided with eccentric wheels, are hinged through the lock pin, and a walnut shell is cracked by opening and closing the handles; and the D-shaped lock pin is matched with two positioning holes in the handle I to form two stations with optimum hand feeling so as to adapt to walnuts of different sizes. The nutcracker is fish-shaped in appearance, and the fish mouth serves as a bottle opener, and small pine nuts and big walnuts can also be cracked. The nutcracker has the characteristics that much labor is saved, the nut cracking process is controllable, the nuts are kept complete and have low probability of cracking, and the nutcracker is compact and reasonable in structure, is portable and multipurpose and can be made into a craft gift.

Description

Eccentric dibit nutcracker

Technical field

The present invention relates to the nutcracker of a kind of daily living article, gift, mechanics teaching aid.

Background technology

Edible walnut need shell, hickory nut particularly, the circle nut, fruit is top sharp, about two half-shells very hard, it is crisp to fry good pulp.When eating often by the broken shell of walnut clip.This series products in the market has following deficiency:

1. all these clip pliers just use lever principle, for reaching the laborsaving long handgrip of using, increase power arm, and small product size is big;

2. because walnut is self-sow, fruit grain differs in size, as hickory nut diameter phi 18～φ 23, like this handgrip to not too draw close or opening angle too big, hold and make not energetically, use inconvenience.

3. because hickory nut pulp and shell are close together, do not have the space, pound with a hammer or use at present these clips all can grasp badly owing to dynamics, with the kernel crushing, while shell and benevolence outwards splash.

4. walnut is in the static pressure state that is subjected to fully in these anchor clamps, and the sphere shell of shell fragility disperses power, and crushing force will be bigger, and clamping force is big with regard to bad control, so shell has broken, kernel is also broken together.Also some product utilization control hand folder closing position prevents that kernel is crowded broken, because walnut granular size shape is different, this device is practical.

Summary of the invention

The object of the invention: solve above-mentioned technical deficiency, increase eccentric wheel under lever principle, it is laborsaving to utilize eccentric inclined wedge augmenting effect to realize.It is the laborsaving walnut clip with 2 working positions.Clip simple in structure, small and exquisite, easy to use, outward appearance is lucky, many usefulness.

For solving the problems of the technologies described above, the present invention adopts technical scheme: band tooth eccentric

wheel part face

20,21 is arranged on the clamping handgrip, and hinged with pin 3, the shell crushing force is along normal direction, more perpendicular to applying grip force, decomposition is just more little in the power of drag direction, thereby can be laborsaving for direction.Laborsaving value is with different variation of the lift angle α of contact position (being normal and the angle of this point and bearing pin line).The α while is by the determining positions of walnut size shape and clamping.Same walnut crushing force, same handgrip length is held the application of force and is the sin α of simple lever effect doubly.Can laborsaving 50% as α=30 °; α=15 ° have only 0.25 times, and namely laborsaving 75%.

The present invention adopts another technical scheme: in clamping process, handgrip forms moment of torsion simultaneously to fruit stone, makes shell rub crowded rolling with the hands, and differential effect is arranged, and is more than having only the broken shell of static pressure effect to be easy to like this, so the labour-saving is many.Whole course of exerting pressure is progressively controlled, and the broken shell process is also carried out gradually.Shell has just broken the application of force again, so that kernel is not just allowed is frangible, integrality is good.

For solving the problem in the background better, the present invention adopts the 3rd technical scheme: hinged place on handgrip one, be provided with 2 holes that are connected 26, by being fixed on the lock pin 3 on the handgrip two, finish the switching of 2 kinds of duties, satisfy the clamping of hickory nut size, the handle openings width is optimum, 90 ° of Fig. 7 of handgrip opening during transposition, D shape pin 29 can be by linkage section between 2 holes 27 to another position, hole, and handgrip rotates back into the folder state for the treatment of.Handgrip is held in the hand suitable, and strength can be controlled.

Nutcracker of the present invention is subsidiary to have bottle opener 28 at handgrip one head.At bearing pin a torque spring 4 is arranged, handgrip is opened reset.This nutcracker outward appearance fish shape, it is very suitable to make handicraft, gift.

The specific embodiment

Fig. 1 is to shown in Figure 8, and nutcracker is made up of handgrip one, handgrip two lock pins and spring.Clamping handgrip one, two mutually hinged forming, spring housing are opened handgrip and are resetted on pin.

Handgrip one has protruding eccentric wheel 20, and handgrip two has recessed eccentric wheel 21, with the walnut clamping face as the flank of tooth, tenon face 24 is hinged by lock pin 3 with groove 23.When handgrip opened, it is big that the retaining part space becomes, and walnut is placed on wherein, when hand-to-hand grip active force by lever principle and the acting in conjunction of eccentric wheel reinforcement under, be easy to press from both sides broken shell.

In the present embodiment, 2 kinds of clamp position of optional Fig. 1 and Fig. 6, convenient adjustable.Handgrip one has 2 holes 26 that link to each other side by side in hinge point, and D type lock pin is fixed in the fraising 22 of handgrip two, cooperates the hole on the handgrip one, is very easy to switch the station state.During switching, handgrip only could be worked at specific subtended angle, and is shown in Figure 7.Pin and hole interlocking during use.It is comfortable to reach grip by clamping part bit position and different station for different big or small fruit grains, and hand just can make and draw strength like this.

The torque spring 4 that resets, be enclosed within that pin is 3 outer, the position in groove 25, contact with groove 23 and 25 bottom lands of 2 handgrips respectively.Its effect can make handgrip open up into and treat the folder state, and 2 operating modes have folder this function that resets later.

Handgrip one head has bottle opener 28, and is convenient and practical.In addition, each is fluted 29,30 for handgrip one or two, by the little pine nut Chinese torreyanut duricrust dry fruit of the folding clamping of handgrip; Each is fluted 31,32 to also have handgrip one or two, is used for the usefulness of the big walnut of clamping.Outward appearance is new and original.Handgrip is fish body and fish tail.Bottle opener fish mouth, hinge is eye, the retaining part cheek.

Above-described embodiment is only for the usefulness that the present invention is described; and be not to be limitation of the present invention; other people are under the situation that does not break away from spirit of the present invention; as adopt eccentric wheel, cam, inclined-plane, helicoid etc. to utilize other modification of inclined wedge augmenting principle, so all technical schemes that are equal to also should belong to protection category of the present invention.
