1. A geological sampling backpack drilling machine comprising a housing, a drilling device and a seat; wherein the housing is an internal-hollow container, with at least one set of limiting rotators arranged on a surface thereof for connecting with a bracket, the bracket detachably connected to the housing through the at least one set of limiting rotators to play a supporting role applied on the housing; and a first included angle can take any value within a range of 0°-90° by the at least one set of limiting rotators, and wherein the first included angle is an angle that is formed between the bracket and a first plane, and the first plane is a plane parallel to a horizontal plane where an axis of the housing is located; and wherein
the drilling device is connected to a drilling rod and configured to drive the drilling rod and a corresponding drilling equipment to move, a surface of the drilling device matched with an interior of the housing, so that the drilling device can move within the housing; and wherein
the seat is set on the surface of the housing, arranged between a tip of the drilling rod and the bracket and rotates around the drilling rod; a rotating handle arranged on a surface of the seat and configured to control a rotation of the seat, at least two sets of rotating members arranged on the surface of the seat and distributed around the drilling rod for detachably connecting with a supporting post, a second included angle taken any value within the range of 0°-90° by the at least two sets of rotating members, wherein the second included angle is a common plane angle between the supporting post and the drilling rod; and wherein
the drilling rod passes through the surface of the housing and the seat, respectively.
