The invention discloses a shovel with a conveniently changed shovel head. The shovel comprises a fixed column body; two first sliding slots are defined on the left and right sides of the fixing columnbody; fixing blocks are fixedly connected to upper portions of the left and right sides of the fixing column body, and second sliding slots are defined on bottom surfaces of the fixing blocks; a fixing rod is placed under each of the fixing blocks; a second sliding block corresponding to the second sliding slot is fixedly connected to one side, close to the fixing block, of the fixing rod, and the second sliding block is engaged in the second sliding slot; sides of the two second sliding blocks adjacent to each other are fixedly coupled with a spring. The shovel, which is easy to replace thehead, achieves the effect of moving the round head and the flat head up and down. It has the advantage of making the flat head and the round head easy to replace. The effect of causing the first pullblock and the second pull block to be respectively stuck to the two limit blocks is achieved. It has the function of restricting the movement of the flat head or the round head, and has the advantagethat the flat head or the round head is fixed when not working.
