The driving gear 3014 drives the screw rod 3015 to rotate and move up and down through the thread under the fixing action of the gear seat, and then drives the connecting rod 309 to move up and down through the bearing seat, so that the support telescopic rod 6 is telescoped, and further the height adjustment of the chain belt screw gun 5 is realized; after the length of the support telescopic rod 6 is adjusted until the nail feeder of the chain belt screw gun 5 contacts the wall or the board surface, the operator turns on the device through the controller 7. The air pump 9 can send compressed air into the air cylinder 4 through the air tank 10. The air cylinder 4 can be telescoped to press the chain belt screw gun 5 against the wall or the board surface, and then the nailing operation is realized. After the nailing is completed, turn off the controller 7, and the air cylinder 4 retracts, and then the position of the device can be moved to perform the next nailing operation.
