The invention provides a grinding clamp and a jig thereof. When an insertion core needs to be located and fixed, only the free end of the jig needs to be pulled towards the side away from a clamp body to enable a first extrusion face to be separated from a second extrusion face by a certain distance; then the insertion core is put between the first extrusion face and the second extrusion face, an elastic locating arm is loosened and restores to the original position under the action of elasticity of the elastic locating arm, and accordingly the insertion core can be fixed between the first extrusion face and the second extrusion face rapidly and firmly, and the fixing speed is high. As the insertion core is fixed at a time, the process of gradual extrusion of a screw is avoided in the process of fixing, small displacement due to gradual extrusion can be prevented, and the insertion core does not move any more once being extruded and fixed, so that the locating is accurate; besides, the elasticity of the elastic locating arm is large, so that the insertion core is extruded and fixed quite firmly, and position changing or falling of the insertion core due to external slight impact is prevented.
