Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Embodiment 1:

[0026] like Figure 1 As shown, a disassembly and assembly structure of a yarn guide includes a base 8, and the base 8 is provided with a plug hole 81, the plug hole 81 is a countersunk hole, and the plug hole 81 extends downward from the upper end of the base 8. Figure 1 , Figure 3 As shown, a first groove portion 811 is provided in the middle of the insertion hole 81 . The first groove portion 811 is a circular groove. The first groove portion 811 is recessed and extends radially outwardly along the insertion hole 81 .

[0027] like Figure 1 , Figure 2 As shown, the inner wall of the plug hole 81 is provided with second grooves 812 on both sides, and the second grooves 812 are recessed and extend radially outwardly along the plug hole 81, and the second grooves 812 are symmetrically arranged. Figure 1 As shown, the first groove portion 811 is located on one side of the second groove portion 812 along the direction in which the guide block 1 is inserted into the insertion hole 81, that is, Figure 1 In the shown orientation, the first groove portion 811 is located below the second groove portion 812 , and the upper end of the first groove portion 811 is connected to the lower end of the second groove portion 812 .

[0028] like Figure 1 As shown, the guide block 1 is installed in the socket 81. The first spring 6 is also installed in the socket 81, the bottom of the first spring 6 abuts against the bottom surface of the socket 81, and the top of the first spring 6 can abut against the bottom surface of the guide block 1.

[0029] like Figure 1 As shown, the main body of the guide block 1 is a cylindrical structure, and the main body of the guide block 1 can be inserted into the insertion hole 81, and the inner diameter of the insertion hole 81 matches the outer diameter of the main body of the guide block 1. The upper end of the main body of the guide block 1 extends outward to form a ring-shaped first extension plate 11, and the outer diameter of the first extension plate 11 is larger than the insertion hole 81. After the main body of the guide block 1 is inserted into the insertion hole 81, the upper end surface of the base 8 can be in contact with the lower end surface of the first extension plate 11.

[0030] like Figure 1 , Figure 3As shown, the guide block 1 includes a second extension plate 13, which protrudes radially outward along the outer periphery of the bottom of the main body of the guide block 1. The size of the second extension plate 13 matches the size of the second groove portion 812. Two second extension plates 13 are also symmetrically arranged. When the guide block 1 is inserted into the socket 81, the second extension plate 13 is inserted along the inner wall of the second groove portion 812, passes through and finally inserted into the first groove portion 811.

[0031] like Figure 1 As shown, when the guide block 1 is inserted into the insertion hole 81, the first spring 6 remains in a compressed state. Figure 1 , Figure 3 As shown, after the second extension plate 13 is inserted into the first groove 811, it can rotate along the inner wall of the first groove 811, so that the second extension plate 13 and the second groove 812 are staggered in the circumferential direction. Figure 4 , Figure 5 As shown, after the second extension plate 13 rotates 90 degrees, the second extension plate 13 and the second groove portion 812 are completely offset in the circumferential direction, and after the offset, under the action of the first spring 6, the upper end surface of the second extension plate 13 abuts against the upper wall of the first groove portion 811, and the upper wall of the first groove portion 811 forms a rotation resistance against the second extension plate 13, so as to prevent the second extension plate 13 from rotating back to the second groove portion 812 and being pushed upward.

[0032] like Figure 1 , Figure 3 As shown, a plug plate assembly 7 is installed on the left side of the base 8, and the plug plate assembly 7 includes an outer cylinder 71, and the outer cylinder 71 is fixedly connected to the outer wall of the base 8. A plug rod 72 is installed in a sliding connection inside the outer cylinder 71, and the left and right sides of the plug rod 72 extend out of the outer cylinder 71 respectively. The outer cylinder 71 is provided with protrusions on both radial sides, and the protrusions are located inside the outer cylinder 71. A second spring 74 is also installed in the outer cylinder 71, and the second spring 74 is inserted into the plug rod 72.

The left end of the plug rod 72 extending out of the outer cylinder 71 is connected to a handle 73, as shown in FIG. Figure 3 As shown, the first groove portion 811 is provided with a third groove portion 813 along the radially outward side of the insertion hole 81, and the third groove portion 813 is recessed and extends radially outward along the outer wall of the first groove portion 811. The right end of the insertion rod 72 extends into the base 8 and is connected to an insertion plate 75. The insertion plate 75 is an arc plate-shaped structure, and the insertion plate 75 can move between the first groove portion 811 and the third groove portion 813.

[0033] Specifically, if Figure 1 , Figure 3 As shown, when the second extension plate 13 is inserted into the first groove portion 811 along the second groove portion 812, the insertion rod 72 is pulled outward by holding the handle portion 73. At this time, the insertion plate 75 is located in the third groove portion 813. When the handle portion 73 is released without rotating the second extension plate 13, the insertion plate 75 is close to the side of the second extension plate 13 and abuts against the outer wall of the second extension plate 13.

[0034] like Figure 3 As shown, the side of the insert plate 75 close to the second extension plate 13 is an inner arc surface, and the outer wall of the second extension plate 13 is an outer arc surface matching the inner arc surface of the insert plate 75, and the two can fit each other inside and outside. When the insert plate 75 is in contact with the second extension plate 13, the guide block 1 is rotated to make the second extension plate 13 rotate along the inner wall of the first groove 811, as shown in FIG. Figure 4 As shown, when the second extension plate 13 is rotated 90 degrees, the insert plate 75 is radially inserted into the first groove 811 along the insertion hole 81 and is inserted between the second extension plates 13 on both sides. The insert plate 75 is just located between the second extension plates 13 on both sides on the circumferential sides, so that the rotation of the second extension plate 13 is restricted, thereby making the guide block 1 stably installed.

[0035] During disassembly, the insert plate 75 is pulled out of the first groove 811, and the insert plate 75 is extended into the third groove 813. At this time, after rotating the second extension plate 13, when the second extension plate 13 is aligned with the second groove 812, the second extension plate 13 is pulled out along the inner wall of the second groove 812 to remove the entire guide block 1.
