Adjustable jig

The invention provides an adjustable jig. The adjustable jig comprises a base, a plurality of first rod pieces, a plurality of second rod pieces and a plurality of supporting pieces; and the first rodpieces and the second rod pieces are arranged in a staggered mode and are connected to the supports pieces. The supporting pieces are arranged at the staggered position of the first rod pieces and the second rod pieces, and the supporting pieces can move along the first rod pieces or the second rod pieces. The first rod pieces or the second rod pieces can move relative to the base. The adjustablejig can adjust the position of the supporting pieces by adjusting the positions of the two rod pieces; by combining the supporting parts in different ways, materials of different sizes can be supported, so that the applicability of the jig is improved; and in the production process, the use of the jig can reduce the types of jigs used in the entire production process, and the management difficulty of the jig is greatly re
