Then, the connecting screw 6 is inserted between the first snap-fit ​​block 4, the through connecting hole 3, and the second snap-fit ​​block 5.

[0038] In the second embodiment, as Figure 1-16 As shown, a self-tightening wire spool includes a wire spool body 1, a central partition 2 is provided in the middle of the wire spool body 1, a through connection hole 3 is provided in the middle of the central partition 2, a first locking block 4 is provided on one side of the central partition 2 and a second locking block 5 is provided on the other side, and a connecting screw 6 passes through the through connection hole 3 to connect the first locking block 4 and the second locking block 5.

[0039] A plurality of positioning slots 7 are provided on the first locking block 4, and a positioning locking plate 8 is provided on the second locking block 5, which passes through the through connection hole 3 and is inserted into the positioning slots 7 to cooperate. The positioning locking plate 8 is an arc-shaped plate, and the outer surface of the positioning locking plate 8 abuts against the inner edge of the through connection hole 3.

[0040] An assembly groove 41 is provided on the outer side of the first snap-fit ​​block 4. A snap-fit ​​plate 9 is provided in the assembly groove 41. A connecting hole 10 is provided on the snap-fit ​​plate 9 to be threadedly connected to the connecting screw 6. Several auxiliary rods 11 are provided on the snap-fit ​​plate 9 that are movably passed through the first snap-fit ​​block 4 or several auxiliary rods 11 are provided on the outward side of the first snap-fit ​​block. The connecting hole 10 is located at the center of the snap-fit ​​plate 9. The first snap-fit ​​plates 4 on both sides of the connecting hole 10 are symmetrically arranged relative to the connecting hole 10, allowing the snap-fit ​​plates 9 to be installed or assembled facing outwards or inwards.

There are at least two auxiliary rods 11, of which at least one auxiliary rod 11 is hollow in the middle and at least one auxiliary rod 11 is provided with a friction outer plate at its top.

[0042] This application adopts this structural form, which allows the first snap-fit ​​plate 4 to be operated inward or outward. When it is inward, it is a normal line-releasing operation. When the auxiliary rod 11 on the first snap-fit ​​plate 4 is outward, it can completely eliminate the friction between the auxiliary rod 11 and the middle partition at the fishing site. The snap-fit ​​plate is then assembled in reverse so that the auxiliary rod 11 on the snap-fit ​​plate is outward, and the line-retrieving operation is performed based on the auxiliary rod 11. This simple operation can broaden the functionality of this application.

[0043] An operating groove 12 is provided in the middle of the outer side of the second snap-fit ​​block 5, and an inner positioning ring 13 is provided in the inner side of the operating groove 12. The connecting screw 6 includes an outer positioning ring 14 that abuts against the inner positioning ring 13. A screw body 15 is provided in the inner side of the outer positioning ring 14, and an operating rod 16 is provided in the outer side of the outer positioning ring 14.

[0044] A snap-fit ​​portion 18 is fixedly provided on the outer side of the first snap-fit ​​block 4 or the second snap-fit ​​block 5. The snap-fit ​​portion 18 includes a vertical auxiliary plate 19, a horizontal fixing plate 20 is provided on the top of the vertical auxiliary plate 19, a fixed snap-fit ​​plate 21 is provided on one side of the horizontal fixing plate 20, a first arc-shaped groove 22 is provided on the inner side of the fixed snap-fit ​​plate 21 to snap-fit ​​the fishing rod, and a movable snap-fit ​​plate 23 is also provided on the horizontal fixing plate 20 to cooperate with the fixed snap-fit ​​plate 21. A second arc-shaped groove 24 is provided on the side of the movable snap-fit ​​plate 23 facing the first arc-shaped groove 22.

[0045] The bottom of the vertical auxiliary plate 19 is provided with a first auxiliary latching part 43, and a second auxiliary latching part 44 is provided at the position of the first latching block 4 or the second latching block 5 that cooperates with the first auxiliary latching part 43. The first auxiliary snap-fit ​​part 43 includes a plurality of transverse snap-fit ​​plates 45 arranged laterally, and an end snap-fit ​​protrusion 46 is provided at the end of the transverse snap-fit ​​plate 45.

A second limiting guide plate 51 that movably abuts against the side of the first limiting guide plate 50 is provided in the assembly groove 47.

[0046] Considering that the initial winding is generally done in a fixed whole, if the snap-fit ​​part 18 is installed on the outside of the first snap-fit ​​block 4 or the second snap-fit ​​block 5, it may easily block the line. Therefore, a snap-fit ​​assembly structure can be adopted. The first limiting guide plate 50 and the second limiting guide plate 51 adopt a side abutment structure to play a guiding role. The positioning snap-fit ​​plate 48 and the transverse snap-fit ​​plate 45 play a snap-fit ​​role to avoid displacement after snap-fit. With this structure, it can be pulled open without damage when pulled open laterally, thereby achieving the purpose of repeated use.

[0047] A top slide groove 25 is provided at the top of the horizontal fixed plate 20.

[0048] Additionally, an operating handwheel can be fixedly connected to the outside of the snap-fit ​​plate 9. That is, the snap-fit ​​plate 9 is used as a connecting component with the operating handwheel configured for use.

[0049] During assembly, the first snap-fit ​​block 4 is first placed on one side of the middle partition 2, and the second snap-fit ​​block 5 is placed on the other side of the middle partition 2. The positioning snap-fit ​​plate 8 and the positioning snap-fit ​​groove 7 are fitted together to position and connect the first snap-fit ​​block 4 and the second snap-fit ​​block 5. Then, the connecting screw 6 is inserted between the first snap-fit ​​block 4, the through connecting hole 3 and the second snap-fit ​​block 5, that is, it is connected to the connecting hole 10 on the other side. For the snap-fit ​​part 18, the first arc groove 22 and the second arc groove 24 are snap-fitted onto the fishing rod. Then, the sliding block is driven by the fastening screw thread to adjust the distance between the movable snap-fit ​​plate 23 and the fixed snap-fit ​​plate, so that it can be snap-fitted onto different fishing rods.
