As shown in fig. 1, optionally, a guide 11 is attached to the housing of the drilling machine 100 to enable attachment of the positioning mechanism 1 to the drilling machine 100. The guide 11 is connected with the drilling machine 100, when the drilling machine 100 moves, the positioning mechanism 1 does not need to be fixedly arranged again, and the working efficiency is improved. In addition, the drilling machine 100 vibrates in the drilling process, the relative position of the drill bit 101 and the positioning mechanism 1 cannot be changed, the positioning piece 13 cannot generate large displacement relative to the drill bit 101, and the positioning precision of the drilling operation is guaranteed. In other embodiments, the guide 11 may be fixed using an external device.

Preferably, the guide 11 is removably attached to the housing of the drilling rig 100 to facilitate servicing and replacement of components in the positioning mechanism 1. After the positioning mechanism 1 is disassembled, the positioning mechanism 1 can be connected to other drilling machines 100, so that the positioning mechanism 1 can be suitable for the drilling machines 100 of different models, and the universality of the positioning mechanism 1 is improved.
