A ratchet block 17 is installed above the pressure plate 9, and the ratchet block 17 is arranged below the retaining ratchet gear 4. The line-releasing seat 1 and the line-releasing seat 2 are connected by two mutually symmetrical locking components 8.

[0026] As an embodiment of the present invention, the contraction groove 11 is arranged along the length direction of the central shaft tube 6, the push block 14 is slidably arranged in the contraction groove 11, and one end of the contraction groove 11 is fixedly connected to the push block 14 through a restoring spring 15.

[0027] As an embodiment of the present invention, one end of the stretch rod 12 is rotatably connected to the inner wall of the contraction groove 11, and the other end of the stretch rod 12 is rotatably connected to the support plate 13, which is respectively arranged at both ends of the central shaft tube 6.

[0028] As an embodiment of the present invention, a turntable 19 is rotatably mounted on the second line-releasing side plate 7, a through hole is opened in the middle of the turntable 19, and the central shaft tube 6 is movably arranged to pass through the through hole.

[0029] As an implementation mode of the present invention, the retaining ratchet gear 4 is in active contact with the ratchet block 17, and the surface of the retaining ratchet gear 4 is fixedly connected with a handle 5 via an extension rod, and the handle 5 is a ring structure.

[0030] As an embodiment of the present invention, guide rails are respectively provided on both sides of the pressure plate groove 16, and the guide rails are slidably connected to both sides of the pressure plate 9.

[0033] Specific working principle:

[0034] First, rotate the locking component 8, one end of the locking component 8 is away from the wire-paying seat 2, then pull out the middle shaft cylinder 6 from the wire-paying seat 2, put the wire roll on the surface of the middle shaft cylinder 6, and then pass the middle shaft cylinder 6 through the turntable 19, the wire-paying seat 2 is close to the wire-paying seat 1, and then flip the locking component 8, the locking component 8 is close to the wire-paying seat 2, and the distance between the wire-paying seat 2 and the wire-paying seat 1 is adjusted so that the wire-paying side plate 27 pushes the push block 14. When the push block 14 is pushed, the stretching rod 12 rotates, and then the support plate 13 is supported on the inner wall of the wire roll to support the wire roll. When the wire is paid out, the fixed ratchet gear 4 rotates, and the fixed ratchet gear 4 rotates on the ratchet block 17. The ratchet block 17 makes the fixed ratchet gear 4 only rotate in one direction, thereby preventing the wire roll from moving in the opposite direction under the inertia state after the rotation stops suddenly, thereby ensuring that when the wire-paying device is used, the wire shrinks too long due to inertia, causing entanglement;

[0035] When the retaining ratchet gear 4 needs to rotate in the reverse direction, it is only necessary to move the pressing plate 9 downward. When the pressing plate 9 moves, the ratchet block 17 can be away from the retaining ratchet gear 4, so that the retaining ratchet gear 4 can rotate freely.

[0036] When the locking assembly 8 is adjusted, the locking adjustment rod 801 drives the locking plug 803 to be inserted into the plug slot 10, and the locking adjustment rod 801 is rotated, and the locking adjustment rod 801 is retracted in the locking flip rod 802, thereby being able to adjust the distance between the pay-off seat 1 and the pay-off seat 2.
