On one side of the inner pipe 100, a symmetrical side opening 102 is provided near the annular orifice 101, and a combining opening 103 is provided at the center of the pipe wall of the inner pipe 100.The clamping mechanism 200 includes two sets of mounting plates 201, a protective sleeve 202, a spring 203, and a sleeve 204.The inner wall of the fastening plate 201 is equipped with the inner tube 100, and a barbed block 205 is located on the inner side of the fastening plate 201. On one side of the mounting plate 201, a rubber band 206 is attached in the vicinity of the annular aperture 101.A protective sleeve 202 is fastened to the outside of the fastening plate 201, and a frustoconical spring 203 is arranged on the outside of the protective sleeve 202. One end of the spring 203 is fixed to the protective sleeve 202. The other end protrudes from the protective sleeve 202 and is fastened to the inner tube 100. A sleeve 204 is provided on the outside of the spring 203.The nail feeding mechanism 300 is composed of an inner sleeve 301 and a nail applicator 302.The bottom of the inner sleeve 301 is provided with an external thread which mates with the internal wall thread of the sleeve 204. The inner sleeve 204 is threadedly secured in the inner sleeve 301. The inner sleeve 301 is provided with the combining hole 2 303. The nail applicator 302 is fitted on the outside of the inner sleeve 301, and the inner wall of the nail applicator 302 is provided with uniformly arranged arcuate grooves 304.The arcuate groove 304 of the nail applicator 302 serves to set the screw.The nail feeding mechanism 300 further includes a fixer 305 fitted on the upper surface of the inner tube 100. On the upper surface of the inner sleeve 301, a positioning hole 306 is provided. On the side of the fuser 305 is a strip aperture 307. In the strip opening 307 is a restriction column fixed in the strip opening 307.When a hand drill is used to screw a screw, the screw is inserted into the arcuate groove 304 of the nail applicator 302 and the fixer 305 is slid downward until its bottom abuts the top cap of the screw. The nail applicator 302 is rotated so that the arcuate groove 304 is located at the corresponding position of the combining hole 2 303 and the combining hole 1 103, and the screw falls into the inner tube 100 and slides down. At this time, the fastening plate 201 clamps the screw. The screw is then screwed in with the hand drill. The procedure is as follows: The other end of the threaded rod is inserted from the top of the inner tube 100 against the screw and drives the screw to rotate and bulge downward, and the screw pulls the barb block 205 of the fixing plate 201 downward so that the barb block 205 slides downward from the side wall of the inner tube 100, and then the screw stretches the fixing plate 201 and then comes out of the inner tube 100, and the installation is completed. At this time, the fixing plate 201 recovers under the rebound stress of the spring 203, and the barb block 205 of the fixing plate 201 is stuck in the side wall of the inner tube 100.
