A boring apparatus having a novel drill rod pusher, comprising: the propelling and holding mechanism comprises an outer shell, a drill rod feeding piece, a drill rod propelling piece and a drill rod rotating piece, wherein the drill rod feeding piece and the drill rod propelling piece are fixed on the outer shell, the drill rod rotating piece is movably arranged on the outer shell and connected with the drill rod feeding piece, the drill rod propelling piece pushes the drill rod rotating piece to slide along the outer shell, the drill rod propelling piece comprises a propelling oil cylinder, a movable pulley block, a fixed pulley block, a belt piece and a guide assembly, the fixed end of the fixed pulley block and the propelling oil cylinder are fixed on the outer shell, the movable pulley block is fixed with the movable end of the propelling oil cylinder, one end of the belt piece is fixed with the length adjusting part, the other end of the belt piece bypasses the fixed pulley block and is wound on the movable pulley block, the guide assembly comprises a pair of guide rods and a pair of sliding butting wheels, the pair of guide rods are arranged on two sides of the pulley frame along the telescopic direction of the movable end of the propulsion oil cylinder, the guide rods are fixed with the outer shell, the pair of sliding abutting wheels are movably arranged on the surface, facing the guide rods, of the movable pulley block, and the pair of sliding abutting wheels are respectively in sliding abutting connection with the pair of guide rods.
2. The boring device with a novel drill rod pusher according to claim 1, characterized in that the abutment surface of the sliding abutment wheel in contact with the guide rod is formed with a curved surface matching the outer surface of the guide rod.
3. The drilling equipment with the novel drill rod propelling part as claimed in claim 2, wherein the movable pulley block comprises a pulley frame, a first movable pulley and a second movable pulley, and the first movable pulley and the second movable pulley are rotatably arranged on the pulley frame.
4. The drilling apparatus with the novel drill rod pusher as claimed in claim 1, wherein the belt member comprises a first belt and a second belt, the first belt is fixed with the drill rod rotating member at one end, the other end passes around the first movable pulley and is fixed with the outer housing, and the first belt makes the drill rod rotating member have a tendency to move towards the drill rod clamping member; one end of the second belt is fixed with the outer shell, the other end of the second belt bypasses the second movable pulley, the fixed pulley block and the length adjusting part, and the second belt enables the drill rod rotating piece to have a trend of being far away from the drill rod clamping piece.
5. The perforating apparatus having a novel drill rod pusher as claimed in claim 4, wherein the outer edge of the outer housing protrudes outward to form a sliding track, the drill rod rotating member includes a sliding bearing plate slidably connected to the sliding track and a drilling motor fixed to the sliding bearing plate, and the length adjustment portion is fixed to the sliding bearing plate.
6. The drilling equipment with the novel drill rod propelling part as claimed in claim 5, wherein a sliding lug is arranged at the bottom of the sliding bearing plate, a sliding groove is formed in the sliding lug, and the sliding track is embedded in the sliding groove.
