Nut clamp

The invention discloses a nut clamp which comprises a first clamp body, a hinge portion and a handle. The first clamp body is in a cup shape and comprises a cup wall and a cup bottom. Sawteeth are evenly arranged on the cup wall. The cup wall, the cup bottom and the sawteeth are of an integrally-formed structure. A second clamp body is arranged between the first clamp body and the handle. The maximum diameter of the second clamp body is smaller than the minimum diameter of the first clamp body. A protrusion is arranged on the inner wall of the second clamp body. A reset spring is arranged between the first clamp body and the second clamp body. A groove is formed in the handle. A clamping portion and a spine portion for pricking out nut meat are arranged inside the groove. The spine portion is clamped into the groove. By the adoption of the clamp, the whole nut clamping process is completed inside the first clamp body, and the phenomenon that nuts are scattered around due to improper operation is avoided; due to the fact that the second clamp body for clamping small nuts is additionally arranged, the clamp can be used for removing various different nut shells, and the practicability of the whole clamp is improved; the spine portion can prick out remaining meat inside the shells, and the whole shelling process becomes easy and sanitary.
