Breaking hammer shell convenient to assemble

The breaking hammer shell convenient to assemble comprises a first shell plate and a second shell plate, the upper portion and the lower portion of the side, opposite to the first shell plate, of the second shell plate are each provided with a fixing mechanism, each fixing mechanism comprises a pair of transversely-arranged screw rods, one end of each screw rod is rotationally connected into a corresponding plate hole through a bearing, and the other end of each screw rod is rotationally connected into a corresponding plate hole through a bearing. The two ends, opposite to the first shell plate, of a pair of screws are in threaded connection with sleeve rods in a sleeved mode respectively, and the two ends, opposite to the first shell plate, of each pair of sleeve rods are fixedly connected with clamping plates. The fixing mechanism has the advantages that by arranging the fixing mechanisms, the two sides of a cuboid assembly can be clamped and limited between the two fixing mechanisms and the inner side of t
