[0045] Preferably, the circumferential outer wall of the U-shaped rod 4008 is fixedly connected with a horizontal plate 9008, and one end of the fixed pipe 9001 is fixedly connected with a ring block 9009, and the circumferential outer wall of the ring block 9009 abuts against the bottom outer wall of the horizontal plate 9008. In the process of inserting the fixed pipe 9001, the ring block 9009 can exert an upward extrusion force on the horizontal plate 9008, further improve the locking effect of the locking assembly 4, and make the clamping assembly 9 realize the effect of locking and strengthening the shell 4001 while ensuring the stable installation of the hook 4003.

[0046] In summary, by means of the technical scheme of the present application, when in use, the staff passes the yarn cylinder 5 from one end of the hook 4003, and at the same time, the yarn wound outside the yarn cylinder 5 is connected with the weft knitting machine, the raw material conveying of the weft knitting machine is completed, and at the same time when the yarn cylinder 5 conveys the yarn, the guide wheel 6002 can play a good guiding role on the yarn, avoiding problems such as mutual entanglement of the yarn during transmission and yarn guiding disorder, and in the process of transmission of the yarn by the guide wheel 6002, the shaft 6005 is driven to rotate, and when the shaft 6005 rotates, the sleeve 6006 sleeved on the outer wall of the shaft 6005 is driven to rotate, and at the same time when the sleeve 6006 rotates, the prompt plate 6008 also rotates, when the yarn is broken, the guide wheel 6002 cannot continue to drive the yarn, so that the shaft 6005 also stops rotating, and when the shaft 6005 stops rotating, the prompt plate 6008 is in a vertical downward state due to gravity and remains different, so that the staff can quickly find the broken yarn, thereby achieving a good prompting effect while guiding the yarn, when the staff needs to adjust the position of the yarn transmission to meet the knitting demand of the weft knitting machine, the staff first presses the pressing rod 4007 to apply downward pressure to the U-shaped rod 4008, when the U-shaped rod 4008 is subjected to the downward pressure, the pressing plate 4005 as a whole descends, at the same time, the pressing column 4012 below the U-shaped rod 4008 also applies downward pressure to the abutment 4013, so that the other end of the connecting rod 4011 is raised, when the other end of the connecting rod 4011 is raised, the movable rod 4002 is driven to rise, so that the pressing plate 4005 below the housing 4001 also moves towards the side close to the housing 4001, thereby effectively releasing the clamping and limiting of the two sets of pressing plates 4005, so that the housing 4001 can move in the fixed frame 3, meeting the adjustment demand of the position of the housing 4001, when the position adjustment of the housing 4001 is completed, the staff releases the pressing plate 4005, and at this time, the second spring 4006 in the compressed state drives the pressing plate 4005 to abut against the inner wall of the fixed frame 3, thereby completing the locking and fixing of the housing 4001, ensuring the stability of the housing 4001 in the fixed frame 3, when the staff replaces the hook 4003 with different inclination angles or thicknesses to meet the feeding demand of the weft knitting machine, the staff can press the fixed tube 9001 to move towards the inside of the housing 4001, when the stop block 9011 contacts the second trapezoidal block 9013 and the third trapezoidal block 9014, the stop block 9011 is stretched (moves towards the inner wall of the fixed tube 9001) and the fourth spring 9012 is compressed, at this time, the stop block 9011 is clamped on the circumferential outer wall of the third trapezoidal block 9014 due to the action of the fourth spring 9012, and then the staff pulls out the fixed tube 9001, in the process of pulling out the fixed tube 9001,The stop block 9011 can drive the second trapezoidal block 9013 and the third trapezoidal block 9014 to move together until the second trapezoidal block 9013 is clamped in the matching groove 9004. At this time, one end of the first trapezoidal block 9003 and one end of the third trapezoidal block 9014 are attached, and the third trapezoidal block 9014 cannot continue to move. The stop block 9011 will slide along the outer wall of the first trapezoidal block 9003. At this time, continuing to pull the fixed tube 9001 can quickly pull it out of the shell 4001, complete the quick disassembly of the hook 4003, and facilitate people to better different inclination or specification of the hook 4003. When replacing a new hook 4003, only the fixed tube 9001 needs to be inserted into the shell 4001 again. The stop block 9011 is driven to move together until the stop block 9011 moves to one end of the first trapezoidal block 9003 which is provided with the matching groove 9004. At this time, the first trapezoidal block 9003 can play a good limiting effect on the stop block 9011, avoiding the fixed tube 9001 from falling off from the shell 4001, facilitating the installation of the hook 4003, and at the same time, the ring block 9009 can exert an upward extrusion force on the horizontal plate 9008 during the insertion of the fixed tube 9001, further improving the locking effect of the locking assembly 4, so that the clamping assembly 9 can realize the effect of locking and strengthening the shell 4001 while ensuring the stable installation of the hook 4003.

[0047] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
