Existing devices for cracking nuts provide only two or three times the balance of power. We offer universal Nutcracker allows you to crack nuts of all sizes, ranging from small — Ø5 mm to 45 mm “giants” at 20 – and 30-fold balance of power.
The device can be made from sheet aluminum with a thickness of 6-8 mm or by casting. On the basis of 1 reinforced socket 2 and a strut 7 which is pivotally connected to the lever 6 by the pusher 5. For fixing a guide tongue moving in a groove carved in base. The liner 9 has a shape of parallelepiped, mutually perpendicular ribs which have different lengths in accordance with the size of nuts.
Multiple gain in power is achieved by the fact that the resultant force of the lever passing through the axis of the follower and a horizontal position of the handle 4 is it an angle of 5-10° (the smaller the angle, the greater the force).
Depending on the size of the nut insert is within the slot, made in the form of the triangular enclosure. While cracking large nuts liner do not use. So the shell did not scatter, fortified pusher plate 3.
