[0034] Specifically, the above-mentioned combination disc includes adjusting mechanism 3 connected between fixed disc 1 and adjusting disc 2, adjusting mechanism 3 includes screw rod 31 rotatably connected in fixed disc 1, adjusting mechanism 3 further includes limiting ring 32 fixedly connected on the outer circle of screw rod 31, limiting ring 32 is rotatably connected in the inside of fixed disc 1, by the setting of limiting ring 32, screw rod 31 keeps in situ rotation relative to fixed disc 1. One end of screw rod 31 penetrates adjusting disc 2 and is screwedly connected with threaded sleeve 34, screw rod 31 drives threaded sleeve 34 to move along the length direction of screw rod 31 when rotating. Positioning plate 35 is installed on the outer circle of threaded sleeve 34, positioning frame 36 is slidably arranged on the outside of positioning plate 35, and positioning plate 35 is non-circular. When adjusting disc 2 cannot rotate relative to fixed disc 1 by the setting of second elastic component 5, due to the setting of positioning frame 36, positioning plate 35 is prevented from rotating with screw rod 31, so that threaded sleeve 34 can only move without rotating, thereby facilitating the spacing adjustment of fixed disc 1 and adjusting disc 2. Positioning frame 36 is installed on the side, away from fixed disc 1, of adjusting disc 2, one end of screw rod 31 is provided with knob 33, and the setting of knob 33 facilitates the rotation of screw rod 31 by tools.

[0035] Further, the above-mentioned combination disc further comprises four sets of first elastic components 4 and four sets of second elastic components 5 arranged between the fixed disc 1 and the adjusting disc 2, the first elastic components 4 and the second elastic components 5 are used to provide elastic force. The four sets of first elastic components 4 are arranged in a ring array, the first elastic components 4 comprise two sets of first positioning seats 41 fixedly connected to opposite surfaces of the fixed disc 1 and the adjusting disc 2, and a first spring 42 is sleeved and arranged on the two sets of first positioning seats 41. The first positioning seat 41 is arranged to prevent the two ends of the first spring 42 from sliding, so as to ensure the accurate position of the first spring 42, and the first spring 42 is arranged to provide elastic force.

[0036] Further, the four sets of second elastic components 5 are also arranged in a ring array, the second elastic components 5 comprise an intermediate plate 51 arranged between the fixed disc 1 and the adjusting disc 2. The two sides of the intermediate plate 51 are provided with second positioning seats 52, and the opposite surfaces of the fixed disc 1 and the adjusting disc 2 are fixedly connected with third positioning seats 53 corresponding to the second positioning seats 52. A second spring 54 is sleeved and arranged on the second positioning seat 52 and the third positioning seat 53, the second positioning seat 52 and the third positioning seat 53 ensure the accurate position of the two ends of the second spring 54, and the second spring 54 provides elastic force. The second elastic components 5 further comprise four sets of fixed blocks 55 fixedly connected to the outside of the intermediate plate 51, a positioning rod 56 is slidably connected in the fixed block 55, one end of each of the four sets of positioning rods 56 is fixedly connected to the fixed disc 1 or the adjusting disc 2, the fixed disc 1 and the adjusting disc 2 are kept synchronous rotation through the arrangement of the fixed block 55 and the positioning rod 56, so that the adjusting disc 2 does not rotate relative to the fixed disc 1. The other end of the positioning rod 56 away from the fixed disc 1 or the adjusting disc 2 is fixedly connected with a limiting disc 57 to prevent the fixed block 55 from being separated from the positioning rod 56.

[0037] In the embodiment, when the elastic force needs to be adjusted, the knob 33 at one end of the threaded rod 31 is rotated by a tool. Due to the effect of the limiting ring 32, the threaded rod 31 can rotate in place in the fixed disc 1, and the threaded rod 31 drives the threaded sleeve 34 to move along the length direction. Because the positioning plate 35 is non-circular and is slidably arranged outside the positioning frame 36, the positioning plate 35 does not rotate with the threaded rod 31 under the condition that the adjusting disc 2 is kept from rotating relative to the fixed disc 1 by the second elastic components 5, so as to ensure that the threaded sleeve 34 can only move linearly, so as to adjust the distance between the fixed disc 1 and the adjusting disc 2.

[0038] In the elastic force providing aspect, the first elastic force assembly 4 and the second elastic force assembly 5 play a key role. In the first elastic force assembly 4, the two groups of first positioning seats 41 on the opposite side of the fixed disc 1 and the adjusting disc 2 are collectively sleeved with the first spring 42, which can provide the basic elastic force for the combined disc. In the second elastic force assembly 5, the second positioning seats 52 on the two sides of the intermediate plate 51 are collectively sleeved with the second spring 54 and the corresponding third positioning seats 53 on the fixed disc 1 and the adjusting disc 2, which further provides elastic force support. At the same time, the fixed block 55 on the outer side of the intermediate plate 51 cooperates with the positioning rod 56, so that the fixed disc 1 and the adjusting disc 2 can keep synchronous rotation, ensuring that the adjusting disc 2 does not rotate relative to the fixed disc 1, and ensuring the stability of the elastic force adjusting process. In the equipment operation process, the elastic force of the spring combined disc can be flexibly adjusted according to the actual demand through the adjusting threaded rod 31, so as to meet the use requirements under different working conditions.
