[0032] The surface of the turntable 302 is fixedly connected with a protrusion 307, and the number of the protrusions 307 is multiple and distributed in a ring shape around the surface of the turntable 302. Through the above technical scheme, the contact area between the operator's hand and the turntable 302 is increased by the setting of the protrusions 307, thereby preventing the hand from being separated during the rotation of the turntable 302. A positioning sleeve 109 is movably connected to one side of the support seat 102, and the inner cavity of the positioning sleeve 109 is fixedly connected to the surface of the connecting shaft 105. A handle 108 is fixedly connected to one side of the positioning sleeve 109, and an anti-slip sleeve 107 is fixedly connected to the surface of the handle 108.

[0033] The working principle of the utility model is as follows: first, by holding the movable seat 213 to rotate, the movable shaft 209 will be driven to rotate inside the support plate 201 during the rotation of the movable seat 213, and at the same time, the setting of the bearing 210 will support the rotation of the movable shaft 209, so that it can rotate more smoothly, and the rotation of the movable seat 213 drives the fixed plate 212 to rotate, and the rotation of the fixed plate 212 drives the fixed sleeve 211 to rotate until the inner cavity of the fixed sleeve 211 completely wraps the surface of the connecting shaft 105, so as to restrict the recovery speed of the threader body 103 and prevent it from being too fast, and then by holding the connecting plate 206 to rotate, the rotation of the connecting plate 206 drives the positioning ring 207 to rotate until the positioning ring 207 is rotated. The inner cavity of the ring 207 clamps the surface of the fixed sleeve 211, and the setting of the limiting plate 208 limits the surface of the fixed sleeve 211 to complete the fixation of the position of the fixed sleeve 211, thereby preventing the surface of the threader body 103 from detaching from the inner cavity of the fixed sleeve 211 during operation. Subsequently, the turntable 302 can be held and rotated, and the screw 306 is driven to rotate by the rotation of the turntable 302. The movable ring 303 is driven to move in the inner cavity of the support platform 301 by the rotation of the screw 306, and the recovery speed of the surface of the threader body 103 can be adjusted. Finally, the handle 108 can be held and rotated, and the positioning sleeve 109 is driven to rotate by the rotation of the handle 108, and the connecting shaft 105 is driven to rotate by the rotation of the positioning sleeve 109.
