[0014] like Figure 1 As shown, the utility model provides an extractor that is suitable for screws of various shapes, including a first rotating member 1, a second rotating member 2, a rotating arm, a first extraction groove 3 and a second extraction groove 4, the transmission belt 5 is arranged between the first rotating member 1 and the second rotating member 2, the rotating arm is detachably connected to one side of the first rotating member 1, and the rotating arm is detachably connected to one side of the second rotating member 2, the other side of the first rotating member 1 is provided with the first extraction groove 3, the other side of the second rotating member 2 is provided with the second extraction groove 4, and a plurality of telescopic columns 6 are provided in the first extraction groove 3 and the second extraction groove 4.

[0015] As an embodiment of the present invention, the telescopic column 6 is in contact with the screw head of the screw.

[0016] As another embodiment of the present utility model, the rotating arm includes a rotating rod 8 and a holding rod 9, the holding rod 9 is vertically connected to one end of the rotating rod 8, the other end of the rotating rod 8 is detachably connected to one side of the first rotating member 1, and the other end of the rotating rod 8 is detachably connected to one side of the second rotating member 2.

[0017] As another embodiment of the present invention, one side of the first rotating member 1 and one side of the second rotating member 2 are both provided with a clamping member, and the other end of the rotating rod 8 is engaged with the clamping member.

[0018] As another embodiment of the utility model, the first rotating piece 1 is smaller in diameter than the second rotating piece 2.

[0019] As another embodiment of the utility model, the first rotating piece 1 is smaller in diameter than the second rotating piece 2.

[0020] The utility model provides a kind of extractor of adaptation multiple shape screw, current prior art is corresponding narrow position in structure, it is inconvenient to visually see screw installation position part and cannot be achieved quickly to take out, the scheme utilizes lever principle to unload force for screw in narrow position, then take out screw quickly by transmission principle.

[0021] The rotating arm is detachably installed on the first rotating piece 1 or the second rotating piece 2, the first take-out groove 3 is arranged on the first rotating piece 1, and the second take-out groove 4 is arranged on the second rotating piece 2. The telescopic column 6 is arranged in the groove, the telescopic column 6 contacts with the screw head, and the telescopic column 6 is deformed in shape when contacting the screw head. This structure design makes the device suitable for screws of various shapes. The telescopic column 6 fixes the screw in the groove, making it easy to take out later. The first take-out groove 3 and the second take-out groove 4 are connected by the connecting rod 7, which provides transmission for the first rotating piece 1 and the second rotating piece 2.

[0022] In use, the first take-out groove 3 and the second take-out groove 4 are aligned and pressed down. When the screw head contacts the telescopic column 6, the telescopic column 6 is compressed. At this time, the screw head shape is formed in the first take-out groove 3 and the second take-out groove 4, and the screw is fixed in the first take-out groove 3 and the second take-out groove 4.
