The utility model aims to solve the problems that the prior tooth holder for the stone crusher comprises a block-shaped tooth holder body, wherein the block-shaped tooth holder body consists of a top working surface and a bottom assembling surface, the right side of the working surface is a long strip-shaped working part, a round positioning hole penetrating through the bottom is vertically arranged at the middle position of the working part, a hexagonal limiting hole is arranged on the round positioning hole, two side edges of the working part are drawn inwards from left to right to present a splayed tail part, a long strip-shaped reinforcing block is arranged on the tail part, an upward-raised sharp-angle-shaped tooth head part is arranged at the left side of the working surface, the tooth head part is connected with the long strip-shaped working part through an inwards-concave curve extending edge, at least one long strip-shaped groove is arranged at the inner side of the curve extending edge, and a long strip-shaped limiting lug is arranged at the middle position of the bottom of the assembling surface, which is positioned at the tooth head part, the two sides of the limiting convex block and the two sides of the bottom of the working part are respectively provided with a surrounding edge which are symmetrical with each other, and the surrounding edges and the limiting convex block are combined to form a limiting device which has limiting and fixing functions.
Preferably, the method comprises the following steps: the circular positioning hole and the limiting hole have the same central point, and the diameter of the circular positioning hole is smaller than that of the limiting hole.
Preferably, the method comprises the following steps: the height of the reinforcing block is smaller than that of the working part, the height of the bottom of the reinforcing block and the height of the bottom of the working part are on the same horizontal plane, and the bottom surface of the reinforcing block is a downward inclined slope surface.
Preferably, the method comprises the following steps: the surrounding edge is perpendicular to the bottom surface of the block-shaped tooth holder body at an angle of 90 degrees, and the length of the surrounding edge is perpendicular to the circle center of the circular positioning hole at an angle of 90 degrees.
The utility model has the characteristics of simple structure uses simple to operate, and structural strength is good, wear-resisting, shock-resistant, long service life etc.
