[0028] The outer wall of the sleeve 1 is slidably connected with a jacket 9, which is an open structure. The inner thread of the jacket 9 is connected with a bolt 2 10, and the jacket 9 is used to clamp and fix the sleeve 1. The bolt 2 10 is rotated to reduce the opening of the jacket 9 to clamp and fix the sleeve 1 to prevent the sleeve 1 from rotating. The outer wall of the jacket 9 is fixedly connected with a connecting seat 11, and the outer wall of the connecting seat 11 is rotatably connected with a bracket 12. A circular hole is opened inside the bracket 12, and a shaft is fixed inside the connecting seat 11. The shaft inside the connecting seat 11 is inserted into the circular hole inside the bracket 12, and the inner threads of the connecting seat 11 and the bracket 12 are connected with bolt 3 13.

[0029] Working principle: When in use, insert the connecting seat 11 into the inside of the bracket 12, so that the connecting seat 11 is rotated and connected to the inside of the bracket 12, and the connecting seat 11 and the bracket 12 are fixed by the bolt 3 13, so that the connecting seat 11 and the bracket 12 maintain a certain angle and no longer rotate flexibly, and then slide the sleeve 1 between the jackets 9, insert the bolt 2 10 into the inside of the jacket 9, and use the rotation of the bolt 2 10 to reduce the angle of the jacket 9, so as to fix the sleeve 1 and prevent the sleeve 1 from rotating, and then align the slot 1 202 inside the angle bracket seat 2 with the fixing rod 102 and insert it, so that The angle bracket seat 2 is inserted into the interior of the sleeve 1, and the other end of the torsion spring 3 is inserted into the interior of one of the fixing plates 101. At this time, the angle of the angle bracket seat 2 is rotated to drive the torsion spring 3 to rotate 3 / 4 counterclockwise. At this time, the position of the second socket 201 is aligned with the position of the first socket 103. At this time, the latch shaft 402 is aligned with the first socket 103 and the second socket 201. Combined with the elasticity of the spring 403, the latch shaft 402 is driven to slide up and insert into the interior of the first socket 103 and the second socket 201, so that the angle bracket seat 2 is limited and fixed in the interior of the sleeve 1, and the angle bracket seat 2 remains stationary after the angle is rotated, and is fixed in the second slot 20 The angles of the tube sleeve 5, the support tube 6, and the feedback assembly 8 inside 3 also change and maintain with the angle of the angle bracket seat 2, and the bracket 12 is fixed on the wall panel. At this time, the feedback assembly 8 is pressed tightly on the disc yarn, and the direction of the support tube 6 and the feedback assembly 8 can be adjusted by the clamp ring on the outer wall of the telescopic tube 7. When the feedback assembly 8 is pressed tightly on the disc yarn, the two feedback wheels 803 are driven to rotate during the rotation of the disc yarn, and the rotation of the feedback wheel 803 drives the feedback core shaft 802 to rotate, and the real data of the disc yarn is transmitted to the command center through the spindle encoder 805. The knitting data is very accurate and solves the problem of weaving. The problems of yarn distortion and yarn breakage, inaccurate warp feeding, etc. are solved, thereby improving the safety performance of the warp knitting machine and increasing the safety and reliability of the machine. When the device is not in use, the feedback component 8 needs to be kept away from the yarn disc. At this time, the pull rod 401 needs to be pulled downward to drive the latch shaft 402 to slide downward and disengage from the inside of the socket 1 103 and the socket 2 201, and the bolt 2 10 needs to be turned and removed to enlarge the opening of the sleeve 9. At this time, the sleeve 1 is no longer clamped by the sleeve 9, so that the elasticity of the torsion spring 3 can be used to drive the sleeve 1 to rotate an angle, so that the angle bracket seat 2 and the sleeve 1 can be reset, thereby achieving the effect of resetting the entire device.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
