[0007] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the drawings in the embodiments of the present invention.

[0008] As shown in the drawings, the screw installation auxiliary tool includes an inner tube 100, a clamping mechanism 200, and a screw feed mechanism 300. An annular stopper 101 is provided at one end of the inner tube 100, and the annular stopper 101 is perpendicular to the side wall of the inner tube 100. A side opening 102 is provided symmetrically on the side of the inner tube 100 closer to the annular stopper 101, and a first combination opening 103 is provided in the center of the tube wall of the inner tube 100.

[0009] The clamping mechanism 200 includes two sets of fixed pieces 201 , a protective cover 202 , a spring 203 , and a sleeve 204 .

[0010] The inner wall of the fixed piece 201 is in close contact with the inner tube 100, and an annular grooved locking member 205 is provided inside the fixed piece 201. A rubber band 206 is attached to the side of the fixed piece 201 close to the annular stopper 101.

[0011] A protective cover 202 is fixed to the outside of the fixed piece 201, and a truncated conical spring 203 is provided on the outside of the protective cover 202. One end of the spring 203 is fixed to the protective cover 202, and the other end extends from the protective cover 202 and is fixed to the inner tube 100. A sleeve 204 is provided on the outside of the spring 203.

[0012] The screw feed mechanism 300 includes an inner sleeve 301 and a screw loading portion 302 . The inner sleeve 301 has a male thread at its bottom, which is mated with and connected to a female thread on the inner wall of the sleeve 204. The sleeve 204 is fixed to the inner sleeve 301 by screwing. The inner sleeve 301 has a second mating opening 303, and the screw loading portion 302 is attached to the outside of the inner sleeve 301. The inner wall of the screw loading portion 302 has uniformly spaced arc-shaped linear grooves 304, in which the screws are placed.

[0013] The screw feed mechanism 300 further includes a fixture 305, which is attached to the upper part of the inner tube 100. The upper part of the inner sleeve 301 has a positioning hole 306, and the side of the fixture 305 has a slot-type opening 307, which has a positioning pillar, and the positioning pillar is fixed in the slot-type opening 307.

[0014] When the screw is attached with an electric drill, the screw is placed in the arc-shaped linear groove 304 of the screw loading part 302, the fixing device 305 is slid down until its bottom touches the head of the screw, and the screw loading part 302 is rotated to align the arc-shaped linear groove 304 with the second combination type opening 303 and the first combination type opening 103, and the screw falls into the inner tube 100 and slides down to the bottom. At this time, the fixing piece 201 clamps the screw. After that, the screw is attached with an electric drill, and the tip of the electric drill is inserted from the top of the inner tube 100, and the screw is pushed in and rotated to push the screw downward. The screw pulls the annular grooved locking member 205 of the fixing piece 201 downward, and the annular grooved locking member 205 slides from the side wall of the inner tube 100, and the screw pushes the fixing piece 201 open and escapes from the inner tube 100, completing the attachment. At this time, the fixed piece 201 returns to its original position due to the repulsive force of the spring 203 , and the annular grooved locking member 205 of the fixed piece 201 slides into the side wall of the inner tube 100 .
