Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0027] like Figure 2 to Figure 5 As shown, a reel finger snap has a structure including a working spring 1, a plug-in ring 2 fixedly arranged on the top of the working spring 1, and a plug-in notch 24 arranged on the plug-in ring 2. The locking structure in this embodiment is arranged at both ends of the plug-in ring 2 close to the plug-in notch 24, so as to control the size of the plug-in notch 24. The positioning member 3 is arranged on the side of the working spring 1 close to the plug-in ring 2, and a plurality of splicing grooves and a plurality of splicing pins are arranged on the positioning member 3. A sliding structure is arranged between each splicing pin and the positioning member 3, so as to make the splicing pin slide relative to the positioning member 3. A synchronization structure is arranged between each splicing pin, so as to synchronize the movement of the splicing pin. A control structure is arranged on the positioning member 3, so as to control the synchronization structure.

[0028] The locking structure in this embodiment includes a first locking plate 21 and a second locking plate 22, which are arranged at both ends of the plug-in ring 2 near the plug-in notch 24. The second threaded hole 221 is arranged on the second locking plate 22, the first sliding hole 211 is arranged on the first locking plate 21, and the adjusting bolt 23 is arranged on the second locking plate 22. The adjusting bolt 23 is slidably connected with the first sliding hole 211, and the adjusting bolt 23 is threadedly connected with the second threaded hole 221. The adjusting bolt 23 makes it possible for the plug-in ring 2 to be more tightly connected to the reel when it is inserted into the reel, and is not easy to fall off or detach.

[0029] The outer surface of the positioning member 3 in this embodiment is a rectangular parallelepiped structure, the control cavity 33 is arranged in the positioning member 3, the first positioning side surface 34 and the second positioning side surface 35 are arranged on both sides of the positioning member 3, the number of splicing grooves is two, including the first splicing groove 31 and the second splicing groove 32, the number of splicing pins is two, including the first splicing pin 41 and the second splicing pin 42, the first positioning side surface 34 is provided with the first splicing groove 31 and the first splicing pin 41. The second positioning side surface 35 is provided with the second splicing groove 32 and the second splicing pin 42, the central axis of the first splicing groove 31 coincides with the central axis of the second splicing pin 42, and the central axis of the second splicing groove 32 coincides with the central axis of the first splicing pin 41. In this embodiment, the first splicing pin 41 and the second splicing pin 42 are used to plug and connect adjacent reel fingers, which not only ensures that the spacing between adjacent reel fingers is consistent, but also makes the connection between adjacent reel fingers more stable. When the reel fingers rotate on the reel, the strength of the reel fingers is improved because the plurality of reels are connected into a whole.

[0030] The sliding structure in this embodiment includes a first sliding rail 81 and a second sliding rail 82, which are fixedly connected to the positioning member 3. The first sliding groove 811 is arranged on the first sliding rail 81, the first sliding member 61 is fixedly arranged at the end of the first splicing pin 41 close to the positioning member 3, the first sliding member 61 is slidingly connected to the first sliding groove 811, the second sliding groove 821 is arranged on the second sliding rail 82, the second sliding member 62 is arranged at the end of the second splicing pin 42 close to the positioning member 3, and the second sliding member 62 is slidingly connected to the second sliding groove 821. This embodiment uses sliding rails and sliding grooves to slide and limit the first splicing pin 41 and the second splicing pin 42, which can effectively prevent the first splicing pin 41 and the second splicing pin 42 from sliding and deviating, and ensure that the splicing pins on the adjacent reel fingers can be smoothly inserted into the splicing grooves.

[0031] The synchronization structure in this embodiment includes a first rotating gear 71, a first sliding rail 81 and a second sliding rail 82 respectively located at the upper end and the lower end of the first rotating gear 71, a first rack 611 fixedly arranged at the end of the first sliding member 61 away from the first sliding rail 81, a second rack 621 fixedly arranged at the end of the second sliding member 62 away from the second sliding rail 82, and the first rack 611 and the second rack 621 are both meshed with the first rotating gear 71. Such a design ensures that the first splicing pin 41 and the second splicing pin 42 have the same movement stroke, so that the adjacent spacings on both sides of the reel fingers are the same.

[0032] The control structure in this embodiment includes a control bolt 5, and a first threaded hole 36 is provided on the positioning member 3, which is threadedly connected to the control bolt 5. The third sliding rail 83 is fixedly provided in the control cavity 33, and a third sliding member 63 is slidably connected to the third sliding rail 83, and the third sliding member 63 is rotationally connected to the control bolt 5. The third rack 631 is fixedly provided at the end of the third sliding member 63 away from the third sliding rail 83, and the second rotating gear 72 is fixedly connected to the central axis of the first rotating gear 71, and the third rack 631 is meshed with the second rotating gear 72. The design of adjusting the control bolt 5 to control the rotation of the first rotating gear 71 is that the control bolt 5 is threadedly connected to the first threaded hole 36, so that after the adjustment of the control bolt 5 is completed, the adjustment result is guaranteed to be in a self-locking state, and the extension length of the first splicing pin 41 and the second splicing pin 42 will not change.

[0033] The limiting hole 632 in this embodiment is provided at the end of the third sliding member 63 close to the control bolt 5, and the second sliding hole 6321 is provided on the side wall of the limiting hole 632 close to the end of the control bolt 5, and the control bolt 5 is slidingly connected to the second sliding hole 6321. The limiting bolt 51 is provided in the limiting hole 632, and is fixedly connected to the control bolt 5. Such a design ensures that when the control bolt 5 rotates close to or away from the third sliding member 63, it can drive the third sliding member 63 to move on the third sliding rail 83.

[0034] This embodiment can also realize the disassembly of a single reel without disassembling other reels. It only needs to rotate the control bolt 5 to make the first splicing pin 41 and the second splicing pin 42 disengage from the adjacent first splicing groove 31 and the second splicing groove 32, and then rotate the adjusting bolt 23 to realize this function, so as to facilitate the disassembly and maintenance of the reel.

[0035] The installation process of this embodiment is as follows: first, the plug-in notches 24 on the plurality of plug-in rings 2 are opened and placed at the position where the reel needs to be installed, and then the fingers are moved so that the first splicing pin 41 on the fingers is inserted into the second splicing groove 32 on the adjacent fingers, and the second splicing pin 42 is inserted into the adjacent first splicing groove 31, and then the rotation control bolt 5 is adjusted to drive the third sliding member 63 to move, and the third sliding member 63 drives the second rotating gear 72 and the first rotating gear 71 to rotate, so that the first splicing pin 41 on the first sliding member 61 and the second splicing pin 42 on the second sliding member 62 move, until the distance between the adjacent fingers reaches a suitable position, the rotation adjustment bolt 23 is adjusted to make the first locking plate 21 close to the second locking plate 22, and the plug-in ring 2 is locked and fixed on the reel.
