[0016] The specific embodiments of the utility model are described in detail below with reference to the drawings.

[0017] As shown in Figure 1 , 2 , 3, it is the specific embodiment of the thumb pipe jacking mechanism of the utility model. The embodiment comprises a mounting frame 0, a cylinder 1 is arranged on the mounting frame 0, a piston 2 is arranged in the cylinder 1, the front part of the piston 2 is connected with a top head shaft 4, the top head shaft 4 extends out of the cylinder 1 from the front part and rotatably sets a top head 5, a spring 3 is arranged at the rear part of the piston 2, the cylinder 1 is connected with a gas source, when the gas source works and ventilates the cylinder 1, drives the piston 2 to move backward, and then makes the top head 5 retract and compresses the spring 3, when the gas source stops working, the piston 2 is moved forward by the restoring force of the spring 3 and is reset, and then the top head 5 extends out.

[0018] In use, the mounting bracket 0 is installed on textile machinery. The top head 5 is a movable top head for axial positioning, and a relatively stationary fixed top head is provided on the other side. This fixed top head is further connected to a motor, which drives its rotation. The fixed and movable top heads then rotate after being pressed against the thumb tube on both sides for limiting their movement, thus winding the yarn. Figure 3 As shown, this is the position where the mandrel 5 retracts to release the thumb tube's limiting position. At this time, the air source is working, supplying air to the cylinder, which pushes the piston 2 to its right limit, compressing the spring 3 and moving the mandrel shaft 4 along with the mandrel 5 to the right. After replacing the thumb tube, the air source is turned off, and the piston 2 can return to its original position to the left under the restoring force of the spring 3, moving the mandrel shaft 4 along with the mandrel 5 to the left. The mandrel 5, in conjunction with the fixed mandrel on the other side, can hold the two ends of the thumb tube in place, thus completing the limiting position. In this invention, the size of the mandrel 5 is adapted to match the cylinder 1, resulting in a relatively small displacement stroke, which is beneficial for accurate axial alignment and reduces the likelihood of deviation during long-term use. The overall bracket does not move during use, improving the stability of each component.

[0019] As an improved specific implementation, the piston 2 is provided with a receiving groove 21 at the rear, and the spring 3 is located in the receiving groove 21 with its rear end abutting against the rear of the cylinder 1.

[0020] like Figure 3 As shown, sealing rings are provided at both ends of the piston 2 and the cylinder 1 housing to provide structural sealing; the space formed by the outer side of the piston 2 and the cylinder 1 allows external gas to enter and drive the movement of the piston 2; a receiving groove 21 is provided at the rear of the inner side of the piston 2, which is used for the insertion of the spring 3 to form a good limit on the spring 3; the rear end of the spring 3 abuts against the rear of the cylinder 1 and provides the restoring force of the piston 2 after compression.

[0021] As an improved specific implementation, an extension rod 6 is connected to the rear of the piston 2. The extension rod 6 extends out of the cylinder 1 from the rear and is connected to an induction magnet seat 7. A magnet 71 is provided on the induction magnet seat 7, and a Hall sensor 8 is provided on the mounting bracket 0. When the piston 2 moves, it drives the induction magnet seat 7 to move synchronously. When the magnet 71 on the induction magnet seat 7 moves to or away from the Hall sensor 8, the position status of the piston 2 and the top head 5 is fed back.

[0022] like Figure 1 , 2 As shown in Figure 3, the position of piston 2 is fed back through the aforementioned sensor settings. After the extended rod 6 is connected to the induction magnet base 7, position sensing can be achieved through the interaction of the magnet 71 on the induction magnet base 7 and the Hall sensor 8. (Reference) Figure 2 , 3, the piston 2 is retracted, at this time the magnet 71 is also retracted away from the Hall sensor 8, that is, the state corresponding to the opening of the thumb tube by the top head 5; after the replacement of the thumb tube is completed, the whole is reset, the magnet 71 is reset to the position of the Hall sensor 8 which is sensed by the Hall sensor 8, that is, the state corresponding to the folding of the top head 5 limiting the thumb tube, at this time the signal can be fed back to the control system. Further, the textile machinery can be prevented from starting during the replacement of the thumb tube by setting, that is, the machinery can only be started when the Hall sensor 8 senses the magnet 71, if the Hall sensor 8 does not sense the magnet 71, that is, the top head 5 is in the open state, the machinery cannot be started; the above can optimize the use of the equipment by pre-setting the control system. In the case of setting the extension rod 6, the spring 3 is further sleeved on the extension rod 6, thereby further improving the structural stability of the spring 3 during compression and release.

[0023] As an improved specific embodiment, the rear part of the top head 5 has a mounting cavity 51, a jacket 52 and two groups of bearings 53 are sleeved in the mounting cavity 51, the two groups of bearings 53 are arranged on the two sides of the jacket 52, and the two groups of bearings 53 are sleeved on the top head shaft 4 for rotatable cooperation.

[0024] As shown in Figure 3 , by arranging the two groups of bearings 53 in the mounting cavity 51, stable sleeving with the top head shaft 4 is realized, stable relative rotation can be realized, that is, the top head shaft 4 does not rotate together with the piston 2, the top head 5 is supported by the two groups of bearings 53 and rotates, thereby stably realizing the winding of the yarn. The jacket 52 is arranged between the two groups of bearings 53, and the three form a stable structure in the mounting cavity 51, thereby improving the structural stability of the sleeving of the top head 5 and the top head shaft 4.

[0025] As an improved specific embodiment, the mounting frame 0 is provided with an outer cover 9, the outer cover 9 is annular and open at both ends, and the connection position of the top head 5 and the cylinder 1 is located in the outer cover 9, and the top head 5 extends out of one end of the outer cover 9 during displacement.

[0026] As shown in Figure 1 , 2 , 3, the outer cover 9 shields the connection position of the top head 5 and the cylinder 1 relative to one end, which can avoid the falling of external sundries and dust, and protects the structure; and the connection position is the relative movement position of the top head 5, the top head shaft 4 and the cylinder 1, and shielding can improve the safety during use of the equipment.

[0027] As an improved specific embodiment, one side of the outer cover 9 is provided with a notch 91, and the notch 91 is used to expose one side of the top head 5.

[0028] As shown in Figure 1 , 3As shown, the setting of the notch 91 facilitates the user to observe the position of the top head 5, the top head shaft 4 and the cylinder 1 through the view provided by the notch 91, and the space provided by the notch 91 can be used for adjustment.

[0029] As an improved embodiment, one side of the cylinder 1 is connected with a quick connector 11, which is used for connecting an external air source.

[0030] As shown, Figure 1 2 As shown, the outer end of the quick connector 11 is convenient for connecting with the pipeline of the external air source, and the inner end is connected with the communication space of the cylinder 1.
