The working principle is as follows: when the invention is used, as shown in figure 5, firstly, a building board to be punched is placed on a plurality of cross rods 8, the friction force between the building board and the cross rods 8 is effectively reduced due to the balls 10 arranged on the top ends of the cross rods 8, and the building board is further effectively prevented from being scratched and damaged when placed on the cross rods 8, and due to the arrangement of the two springs 9 in the T-shaped chute 6, every two adjacent cross rods 8 are always in a joint state under the action force of the two springs 9, so that the support stability of the cross rods 8 can be effectively ensured, then a worker twists the two threaded rods 16 through the two handles 17 to enable the two fixing plates 14 to move towards the two sides of the building board so as to clamp the two sides of the building board, so that the building board can be effectively fixed on the cross rods 8, and the building board is prevented from shaking left and right in the punching process, then two fixing bolts 29 are unscrewed, so that the side ends of the fixing bolts 29 are separated from the threaded holes 30, the first positioning plate 27 is not fixed with the side wall of the fixing plate 14 through the fixing bolts 29, and because the upper end surface of each tooth on the rack 24 is parallel to the horizontal plane and the lower end surface of each tooth is obliquely arranged, the rack 24 pushes the inclined surface of the side end of the square bolt 26 to freely slide downwards under the action of the counterweight block 23, meanwhile, the first fixing plate 21 also synchronously falls downwards under the action of the counterweight block 23 until the bottom end of the first fixing plate 21 is attached to the top surface of the building board, and at the moment, the inclined surface of the side end of the square bolt 26 is still embedded in the insection of the rack 24 under the action of the tension spring 28, so that the rack 24 can only move downwards but not move upwards under the action of the square bolt 26, and therefore, two sides of the top surface of the building board can be tightly, the condition that the two ends of the building board are tilted up due to vibration in the punching process is effectively prevented, and the rubber pads are attached to the bottom end of the first fixing plate 21 and the opposite side walls of the two fixing plates 14, so that the building board can be effectively prevented from being damaged when being clamped and fixed. After the building board is fixed, the punching operation can be implemented, when the building board is punched, the position of the drill rod 57 needs to be adjusted firstly, the drill rod 57 is aligned with the punching position on the building board, when the position of the drill rod 57 is adjusted, the motor 32 is started to adjust the position of the drill rod 57 in the left-right direction, the motor 32 can move the screw nut 35 left and right through the screw 33, when the screw nut 35 moves left and right, the four positioning rods 55 can be driven by the n-shaped plate 36 to move synchronously, when the four positioning rods 55 move left and right, the first n-shaped plate 44 can be synchronously moved by the four positioning cylinders 54, when the first n-shaped plate 44 moves left and right, the second motor 56 and the drill rod 57 can be driven to move left and right synchronously, after the position of the drill rod 57 is adjusted in the left and right direction, the position of the drill rod 57 can be adjusted in the front-back direction by the first, when the first screw nut 40 moves in the front-back direction, the two limiting plates 47 and the square sliding block 46 are driven to move in the front-back direction through the guide cylinder 41 and the hydraulic cylinder 43, the limiting plates 47 can drive the second motor 56 and the drill rod 57 to move in the front-back direction, and the positions of the motor 56 and the drill rod 57 can be adjusted in the front-back direction through the first motor 37, so that the drill rod 57 can be accurately aligned with a punching point on a building plate, the punching accuracy is effectively improved, due to the arrangement of the first balls 48, the friction force between the transverse plate of the first n-shaped plate 44 and the two limiting plates 47 is effectively reduced, and the stability in sliding is improved. After the position of the drill rod 57 is adjusted, when the second motor 56 is started, the extension end of the hydraulic cylinder 43 is controlled by an external hydraulic station to extend, when the hydraulic cylinder 43 extends, the first n-shaped plate 44 and the four positioning cylinders 54 are synchronously driven by the two limiting plates 47 to move downwards, when the four positioning cylinders 54 move downwards, the two triangular plates 18 are synchronously driven by the two positioning plates 22 to move downwards, when the two triangular plates 18 move downwards, the tips of the two triangular plates are inserted between the two adjacent cross rods 8, so that the two cross rods 8 which are originally attached are separated towards two sides, a punching space is reserved at the positive lower end of the drill rod 57, the bottom end of the drill rod 57 is contacted with the top surface of the building board and starts to punch after the two adjacent cross rods 8 are extruded and separated by the triangular plates 18, the drill rod 57 is effectively prevented from penetrating through the building board to damage the cross rods 8, and waste scraps generated during punching can fall, the purpose of collecting punching scraps in a centralized manner is effectively achieved. When the building board is taken down from the plurality of cross bars 8 after the hole is drilled, firstly, the square bolt 26 is pulled towards the direction of the vertical plate 11 through the first positioning plate 27, so that the side end of the square bolt 26 is separated from the insection on the rack 24, then the rack 24 and the first fixing plate 21 are pulled upwards through the first handle 25, so that the bottom end of the first fixing plate 21 is separated from the building board, then the first positioning plate 27 is loosened, so that the side end of the square bolt 26 is re-embedded into the insection on the rack 24 under the action of the tension spring 28, then the fixing bolt 29 is tightened, the side end of the fixing bolt 29 is screwed into the threaded hole 30, the first positioning plate 27 and the fixing plate 14 are fixedly connected through the fixing bolt 29, so that the square bolt 26 cannot retreat due to the jacking of the rack 24, and the rack 24 is limited and fixed by the square bolt 26, and the first fixing plate 21 cannot freely fall, the building board can then be removed from the plurality of cross bars 8 by screwing the two threaded rods 16 with the two handles 17 so that the two fixing plates 14 are separated from the two sides of the building board.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
