[0002] The hole-drilling machine is one of the most frequently used hole-drilling machines in daily cutting and connecting operations. In the past, since the drilling rotation of the equipment is an automatic motor device, and the drill feed device is manually fed, the feed speed can only be controlled by feel and experience during the drilling operation. Since human operation is susceptible to interference, there are some uncertainties in the hole-drilling feeding process. For example, in actual operation, the manual feed speed does not match the motor drilling rotation speed, and the feed speed is too slow, causing the drill to idle; if the feed speed is too fast, the drill may get stuck easily, causing great wear and tear on the cutter head, and it may also easily cause the risk of rebound of the hole-drilling machine, which not only causes inconvenience to construction operations, but also poses a great threat to personal safety.
