In this embodiment, the damping disc 3 is a cylindrical hollow aluminum member, the damping disc 3 is sleeved on the bobbin 201, the opening of the damping disc 3 faces the cylinder 2 with the magnetic block 22, a plurality of pairs (four pairs in the figure) of left-right symmetrical grooves 31 with successively deepened depths are formed on one end surface of the damping disc 3, and in fig. 4, the grooves 31 are formed on the end surface of a hollow convex ring 32 extending rightwards from the inner bottom surface of the damping disc 3; the left end and the right end of a pin shaft 51 fixed on the reel shaft 201 can be embedded into any one pair of grooves 31, a first spring 52 is sleeved on the reel shaft 201, two ends of the first spring 52 respectively abut against the outer bottom surface of the damping disc 3 and the bulge of the reel shaft 201, namely abut against the other end surface of the damping disc 3, so that the damping disc 3 can abut against the pin shaft 51 after moving rightwards (see figure 2) along the reel shaft 210, and the damping disc 3 can rotate along with the reel shaft 201. Thus, if the axial position of the damping disc 3 needs to be adjusted, the damping disc 3 is pressed leftwards in the axial direction, the hand is loosened after the damping disc 3 is rotated for an angle, then the pin shaft 51 falls into the corresponding deeper or shallower groove 31 after the damping disc 3 moves rightwards under the action of the first spring 52, so as to change the distance between the damping disc 3 and the magnetic block 22, namely, at this time, the depth difference of each groove 31 is reasonably selected, and the purpose of roughly adjusting the damping force can be achieved.

For the convenience of assembly, the damping seat 1 is composed of a first damping seat 11 and a second damping seat 12 which are distributed along the axial direction and detachably connected with each other by a plurality of screws (three screws in the figure), wherein the second damping seat 12 is disposed adjacent to the damping disk 3, the second damping seat 12 further includes an annular body 121 and a mounting portion 122 located at the middle of the annular body, the mounting portion 122 is connected with the annular body 121 by at least two radial arms 123 (two radial arms in the figure), and the fixture block 124 is located on the outer side wall of the annular body 122 of the second damping seat 12. When the damping seat 1 needs to be disassembled and assembled, the damping seat 1 can be detached from or installed on the main body 10 only by rotating the damping seat 1 to enable the fixture block 124 to leave the fixture groove 101 of the main body or to be positioned in the fixture groove 101. The assembly of the parts of the damper base 1 is hereinafter referred to as a damper base assembly a. In order to prevent the latch 124 from being accidentally disengaged from the latch slot 101, a locking assembly 9 capable of controlling the damping seat 1 to rotate is further disposed between the second damping seat 12 and the main body 10. Of course, the detachable structure can be omitted, and the use of the damping structure is not influenced.

The opening part of the cylinder body 2 faces the damping disc 3 so that the damping disc 3 can partially extend into the opening part, eight through holes 21 are formed in the side wall of the cylinder body 2 and are distributed at intervals along the circumferential direction, and magnetic blocks 22 are embedded in the through holes 21; the bottom of the cylinder 2 is located between the first damping seat 11 and the second damping seat 12, and two ends of the second spring 6 are respectively abutted between the second damping seat 12 and the bottom of the cylinder 2, so that the cylinder 2 always has a tendency to move towards the first damping seat 11, the cylinder 2 is prevented from moving freely in the axial direction, and the annular ring 421 and the annular groove 23 can be well meshed. The side wall of the cylinder 2 is also provided with an axial hole 24 for the radial arm 123 of the second damping seat 12 to pass through, so as not to affect the axial movement of the cylinder 2 in the damping seat, but also to provide a guide for the axial movement of the cylinder 2.

The driving member in this embodiment includes a first gear 41 and a second gear 42 engaged with the first gear 41, which rotate coaxially with the adjusting knob 4, in this embodiment, the adjusting knob 4, the first gear 41, and the second gear 42 are all mounted on the first damping seat 11, in order to avoid interference, the first damping seat 11 further has a notch, an elastic arm 111 extends from an edge of the notch, a support ring 112 is formed at an end of the elastic arm 111, the adjusting knob 4 and the first gear 41 are mounted on the support ring 112, the first damping seat 11 further axially extends a short shaft 113 on an end surface facing the second damping seat 12, the second gear 42 is rotatably sleeved on the short shaft 113, and an annular ring 421 whose end surface is spirally raised and an annular groove 23 whose bottom is spirally lowered are provided between the end surface of the second gear 42 and the bottom surface of the cylinder 2. When the damping force needs to be finely adjusted, only the adjusting knob 4 needs to be rotated to drive the first gear 41 and the second gear 42 to rotate, and at this time, the second gear 42 can push the cylinder 2 to move axially towards the damping disk 3 side or away from the damping disk 3 side through the matching of the annular ring 421 and the annular groove 23 between the second gear and the cylinder 2, so that the distance between each magnetic block 22 and the damping disk 3 can be finely changed.

In the process of fine adjustment of the damping force, in order to avoid excessive rotation, the first damping seat 11 is provided with two limiting raised heads 114 distributed at intervals along the circumferential direction, and the end surface of the second gear 42 is provided with a resisting part 422 respectively matched with the two raised heads 114. When the stopping part 422 is against the two raised heads 114 in turn, the second gear 42 can be prevented from rotating in the forward or reverse direction, and the maximum rotation angle of the adjusting knob 4 can be controlled.

The side cover 30 is provided with a mounting hole 301 for the adjusting button 4 to partially pass through at a position corresponding to the support ring 112. In order to conveniently realize the coarse adjustment and fine adjustment functions of the damping force, the side cover 30 and the damping base 1 are detachably connected, and can be unlocked through the button assembly 8, so that the side cover assembly described below can be quickly detached from the damping base assembly. Specifically, as shown in fig. 8, 9 and 10, a cover 81 is fixed on the inner wall of the side cover 30, and a tube 83 is further fixed by a screw, the tube 83 is formed by a thick tube 831 and a thin tube 832 with different diameters, wherein the thin tube 832 is adjacent to the inner wall of the side cover 30, and an outer step 833 is formed between the thick tube 831 and the thin tube 832, although the outer step 833 can also be directly formed by a flange arranged on the outer wall of the tube 83. For the convenience of manufacturing, the side wall of the thick tube 831 is integrally formed with an elastic clip 82, the thin tube 832 is sleeved with a limit piece 84 capable of sliding along the thin tube 832 and abutting against the outer step 833, the limit piece 84 is further fixed to the first damping seat 11 through a screw, a third spring 85 is arranged between the thick tube 831 and the bottom of the clip seat to enable the tube 83 to always move outwards, the thin tube 832 is sleeved with a fourth spring 86, the fourth spring 86 is a torsion spring, two ends of the fourth spring 86 are respectively positioned on the limit piece 84 and the side cover 30 to enable the side cover 30 to have a tendency of automatically rotating to open an angle after moving outwards, and the side cover 30 is an assembly after the elastic clip 82 and other parts are installed, which is called a side cover assembly. Thus, when the elastic clamping leg 82 is separated from the bayonet 126 by pressing the button assembly 8, under the action of the third spring 85, the tube body 83 and the side cover 30 have a tendency of moving axially outward, when the tube body 83 moves to an outer step to abut against the limiting piece 84, the tube body 83 and the side cover 30 are hung on the first damping seat 11 through the limiting piece 84, and simultaneously, the torsion of the fourth spring 86 is utilized to enable the side cover 30 to automatically rotate eccentrically by an angle in the process of moving axially outward, that is, at this time, the side cover assembly is connected with the damping seat assembly, and at this time, due to the abutting of the limiting piece, the third spring is still located in the clamping seat, and the fourth spring is still sleeved on the thin tube body; however, since the side cover 30 is rotated by a certain angle to open the inner cavity, the user can insert the inner cavity to operate the locking assembly 9 and perform the above-mentioned rotation operation on the damping seat assembly a.

In order to make the elastic locking leg 82 and the locking opening 126 fit and loosen properly in the process of assembling and disassembling the side cover 30, a plurality of lugs 115 radially extend from the outer side wall of the first damping seat 11, and each lug 115 is sleeved with an elastic ring 116 for contacting with the side cover 30. The elastic clamping feet 82 can be smoothly hooked on the bayonet 126 by utilizing the extrusion between each elastic ring 116 and the side cover 30, so that the phenomenon that the side cover 30 is loosened due to the fact that the elastic clamping feet 82 are too short to clamp the bayonet 126 and too long is avoided, and the defects can be effectively eliminated, and the outer surface of the side cover 30 can be stably connected with the main body 10 after the side cover 30 is smoothly clamped on the damping seat 1.

Therefore, when the throwing damping force is adjusted, the damping force is roughly adjusted, the damping seat assembly A can rotate only by pressing the button assembly 8, opening the side cover and pressing the locking assembly 9, the damping seat assembly A is separated from the clamping groove 101 on the main body, the damping seat assembly is detached from the main body, at the moment, the damping disc 3 is exposed outside, at the moment, the damping disc 3 is pressed rightwards by hand, and the damping disc 3 is far away from the pin shaft 51 due to the stress and compression of the first spring 53; then the damping disc 3 is rotated to select a proper gear (namely, grooves with different depths) and then the hand is released; at this time, after the external force is removed, the first spring 53 again presses the damping disk 3 against the pin 53 due to the elastic action. Due to the fact that the grooves 31 with different concavity degrees are selected, the depth of the damping disc 3 entering the cylinder 2 is different, and damping force generated by cutting magnetic induction lines is also different greatly. Then, the damping force is finely adjusted, and the required damping force is accurately selected only by rotating the adjusting button 4; when the adjusting knob 4 is rotated to a certain angle, the adjusting knob 4 cannot rotate any more because the raised head 114 of the first damping seat 11 will collide with the abutting part 422, which indicates that the adjusting knob 4 has been adjusted to the maximum position or the minimum position.
