The utility model discloses produced beneficial effect:

the utility model discloses two ends at the back of single grate plate respectively constitute a "Y" font by three fore-and-aft protruding muscle boards and connect the fork, and the left and right binary arms of its front end of each "Y" font connection fork parallels, and its rear end center extends for the fork handle. The fork handle of the front grate plate is inserted into the hinge between the two fork arms of the rear grate plate, thus connecting the front grate plate and the rear grate plate into a whole. The transverse through rod penetrates into hinge holes formed by inserting fork handles and fork arms of the left and right grate plates to connect the left and right grate plates into a whole. A groove is formed between the outer fork arms of the Y-shaped connecting forks of the front and the rear grate plates (namely the outer side shoulders of the Y-shaped connecting forks), and the groove is an insertion groove of the teeth of the single-row toothed gear, so that a Y-shaped gear rail which is specially arranged on the grate in the prior art is omitted, the double-row toothed gear is not needed, the light single-row toothed gear is used, the two sides of the grate are driven, the structure of the grate is greatly simplified, the materials are saved, the weight is light, the price is low, and the using effect is good.
