[0018] Example 1
[0019] See also Figure 1-4 , the utility model provides a technical solution: a positioning device that is convenient for auxiliary adjustment, comprising: a fixed base 1 and an adjustment positioning mechanism 2;
[0020] The fixed base 1 is in the shape of a disc, and the fixed base 1 can stably drive the structure above to effectively fix it. The adjusting and positioning mechanism 2 is arranged directly above the fixed base 1. The gap between the adjusting and positioning mechanism 2 and the inner wall of the through hole of the yarn tube can be adjusted by adjusting the positioning mechanism 2, so as to avoid the phenomenon of falling off during the rotation of the yarn tube. The adjusting and positioning mechanism 2 includes a No. 1 fixed frame 201 welded above the fixed base 1. The No. 1 fixed frame 201 can protect the internal structure. A threaded hole is opened above the No. 1 fixed frame 201 to provide stability of the internal structure, and when the internal structure rotates, the internal structure can The second fixing frame 202 is welded on the top of the first fixing frame 201, and the second fixing frame 202 can provide the internal structure with stable fixation. The outer wall of the second fixing frame 202 is provided with a circular through hole and a rectangular through hole. The circular through hole and the rectangular through hole can provide the internal structure with stable displacement. A guide rod 206 slidably connected to the inside of the second fixing frame 202 can stably displace inside the second fixing frame 202, and in the process of displacement of the guide rod 206, it can synchronously drive the structure connected on one side to move synchronously. One end of the guide rod 206 is integrally formed with a convex plate, and the guide rod 206 is When the second fixed frame 202 moves inside the circular through hole, the convex plate at one end of the guide rod 206 can prevent the guide rod 206 from deviating from the circular through hole of the second fixed frame 202. The limit plate 207 welded at one end of the guide rod 206 can reduce the distance between the limit plate 207 and the inner wall of the yarn tube when the limit plate 207 is stably displaced by the guide rod 206. The threaded screw 203 connected to the threaded hole of the first fixed frame 201 is rotated. The threaded screw 203 can be stably displaced during the rotation. The handle 204 fixed at one end of the bottom of the threaded screw 203 is engaged. By holding the handle 204, the threaded screw connected above can be driven 203 is stably displaced by rotation. The conical block 205 welded on one end of the top of the threaded screw 203 can drive the outer structure to be squeezed and pushed when the conical block 205 is synchronously displaced. The trapezoidal block 208 welded on one end of the limit plate 207 can drive the limit plate 207 to move synchronously when the trapezoidal block 208 is squeezed by the conical block 205. The spring 209 is sleeved on the guide rod 206, and the two ends of the spring 209 are respectively welded to the convex plate of the guide rod 206 and the inner wall of the second fixed frame 202. The spring 209 is connected to the convex plate on one side of the guide rod 206, and can drive the guide rod 206 to perform reset displacement work.
[0021] The yarn tube is sleeved on the outer side of the limit plate 207. At this time, the bottom of the yarn tube will be limited by the No. 2 fixed frame 202 on the No. 1 fixed frame 201. By holding the handle 204 inside the No. 1 fixed frame 201, when the handle 204 is rotated, the handle 204 can drive the threaded screw 203 to make a selection. At this time, during the rotation of the threaded screw 203 inside the No. 1 fixed frame 201, the upper conical block 205 can be driven to move. During the displacement of the conical block 205, the outer trapezoidal block 208 can be squeezed and displaced. At this time, the trapezoidal block 208 can drive the limit plate 207 to change its position. At this time, the limit plate 207 is stably moved on the outside of the No. 2 fixed frame 202 through the guide rod 206. The guide rod 206 is reversely pulled and reset by the spring 209, and the limit plate 207 can be kept in the place after the changed position, thereby reducing the gap between the limit plate 207 and the yarn tube through hole.
[0022] Example 2
[0023] See also Figure 1-4 , the utility model provides a technical solution: a positioning device that is convenient for auxiliary adjustment, including: a protection mechanism 3;
[0024] The positioning device for auxiliary adjustment also includes a protective mechanism 3, which can provide effective protection for the internal structure of the No. 1 fixed frame 201 to prevent impurities from contacting the internal structure of the No. 1 fixed frame 201. The protective mechanism 3 includes a protective cover 301 connected to the outer wall of the No. 1 fixed frame 201 by a hinge. The protective cover 301 can be quickly opened and closed by rotation. The connecting block 302 welded on the outer wall of the protective cover 301 can effectively fix the closed protective cover 301 in the future. The elastic block 303 is bolted to the top of the fixed base 1. The elastic block 303 is made of plastic and can limit the connecting block 302 by deformation.
[0025] When the handle 204 needs to be held for rotation, the protective cover 301 is pushed. The protective cover 301 can be rotated on one side of the fixed frame 201 through the hinge. Because the connecting block 302 is engaged in the inside of the elastic block 303, during the rotation of the protective cover 301, the connecting block 302 is synchronously driven to change position. At this time, the connecting block 302 will drive the elastic block 303 to deform, so that the connecting block 302 can leave the inside of the elastic block 303, thereby providing a stable rotation and opening of the protective cover 301.
[0026] Working principle: The yarn tube is sleeved on the outer side of the limiting plate 207. At this time, the bottom of the yarn tube will be limited by the No. 2 fixed frame 202 on the No. 1 fixed frame 201. When it is necessary to hold the handle 204 to rotate, the protective cover 301 is turned. The protective cover 301 can be rotated on one side of the No. 1 fixed frame 201 through the hinge. Because the connecting block 302 is engaged with the inside of the elastic block 303, during the rotation of the protective cover 301, the connecting block 302 is synchronously driven to change its position. At this time, the connecting block 302 will drive the elastic block 303 to deform, so that the connecting block 302 can leave the inside of the elastic block 303, thereby providing a stable rotation and opening of the protective cover 301. By holding the inside of the No. 1 fixed frame 201 The handle 204 can drive the threaded screw 203 to select when the handle 204 is rotated. At this time, during the rotation of the threaded screw 203 inside the No. 1 fixed frame 201, the upper conical block 205 can be driven to move. During the displacement of the conical block 205, the outer trapezoidal block 208 can be squeezed and displaced. At this time, the trapezoidal block 208 can drive the limit plate 207 to change its position. At this time, the limit plate 207 is stably moved outside the No. 2 fixed frame 202 through the guide rod 206. The guide rod 206 is pulled back and reset in the opposite direction by the spring 209, so that the limit plate 207 can be kept in the place after the changed position, thereby reducing the gap between the limit plate 207 and the yarn tube through hole.
