If 4 holes need to be drilled simultaneously, 4 guide posts and 4 sliding sleeves can be arranged, and the horizontal connecting rods are used for connecting the 4 sliding sleeves.

In one embodiment, the connecting member is a horizontal connecting rod. The arrangement is that the horizontal connecting rods are convenient to process, and the connecting rods can be inclined in practice as long as each sliding sleeve can be fixedly connected. The shape of the connecting member is not limited to a rod, and may be a tube, a block, or the like.
