[0021] The specific embodiments of the present invention are further described in conjunction with the accompanying drawings.

[0022] As shown in the figure, a magnetic brake structure of a water drop wheel includes a brake seat 5, a brake pad 7, a return spring 6 and a brake cover 8. Two spiral slide rails 51 are provided on both sides of the brake seat 5. The two brake pads 7 are slidably arranged on the outside of the slide rails 51. One end of the return spring 6 is connected to the end face of the slide rail 51, and the other end is connected to the brake pad 7. The brake cover 8 is fixed to the end of the brake seat 5, and the brake pad 7 is provided with a plurality of magnetic sheets 12.

[0023] A retarding cam 4 is arranged on the outer side of the rear part of the brake seat 5 .

[0024] The bottom end surface of the brake seat 5 is provided with a gear.

[0025] The brake cover 8 is fixed on the brake seat 5 by screws 9 .

[0026] The return spring 6 is an arc spring.

[0027] The middle of the brake seat 5 and the brake cover 8 are provided with a circular hole for the axis of the spool assembly 10 to pass through.

[0028] like Figure 2 , 3 As shown, the bottom of the brake seat 5 is connected to the winding wheel cover 1.

[0029] The bearing 3 at the bottom of the spool assembly 10 is arranged in the circular hole of the brake seat 5. A gasket 2 is arranged between the bearing 3 and the reel cover 1. The top of the magnetic brake structure is connected to the spool assembly 10. The spool assembly 10 is provided with a spool bearing 11. The spool shaft passes through the circular hole and the bearings 3 on both sides. The spool assembly 10, the bearing 3, the gasket 2 and the spool bearing 11 are all prior art and are used in conjunction with the magnetic line brake structure.

[0030] The working principle of the magnetic brake structure is as follows:

[0031] The spiral brake pad 7 slides on the slide rail 51 of the brake seat 5, forming a lateral precession, and the return spring 6 keeps the brake pad 7 in an initial low position. When the spool rotates, according to Lenz's law, the spool will generate a resistance force with the magnetic sheet 12 on the brake pad 7. When the brake pad 7 is subjected to force, the brake pad 7 slides on the spiral track from a low position to a high position. The tension on the brake pad 7 is proportional to the rotation speed of the spool, and according to the rotation speed of the spool, the reaction force of the return spring 6 is overcome in proportion, so that the brake pad 7 moves laterally a certain proportional distance. In this way, the inner wall of the spool also has a certain proportion of increased coverage and generates a corresponding braking force, so that during the casting process, the brake pad 7 can have an adaptive and appropriate braking force, making the casting process more stable and the experience more comfortable.
