[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] The rotational connection described in this device refers to the process of baking the bearing on the shaft, providing a spring retaining ring groove on the shaft or the shaft hole, and clamping the elastic retaining ring in the retaining ring groove to achieve axial fixation of the bearing and realize rotation; the articulation refers to a connection method that is active on connecting parts such as hinges, pins and short shafts.

[0024] The present invention will be described in detail below with reference to the accompanying drawings.

[0025] Embodiment 1:

[0026] The following is combined with Figure 1-2 The independent selection synchronous linkage system includes: a main shaft 1, a sleeve shaft 2, the sleeve shaft 2 is rotatably connected to a bearing seat 3, the bearing seat 3 is fixedly arranged, the sleeve shaft 2 is connected to an output transmission member 4, the main shaft 1 and the sleeve shaft 2 are concentrically arranged, the sleeve shaft 2 is provided with a plurality of sleeve shafts, and the main shaft 1 and the sleeve shaft 2 are connected and disconnected through a clutch mechanism 5;

[0027] The clutch mechanism 5 includes teeth 51 and tooth grooves 52. The teeth 51 are connected to the outside of the sleeve shaft 2, and the tooth grooves 52 are arranged inside the sleeve shaft 2. The teeth 51 and the tooth grooves 52 can be slidably engaged, and the spindle 1 is loosely fitted in the spindle frame 53.

[0028] When synchronous adjustment of the three phases is required, the main shaft 1 is controlled to slide inward along the main shaft frame 53, and the teeth 51 slide into the tooth grooves 52 in the sleeve shaft 2 and fit with the tooth grooves 52. At this time, the main shaft 1 is rotated, and the main shaft 1 drives all the sleeve shafts 2 to rotate simultaneously to transmit power to the output transmission member 4, thereby realizing simultaneous adjustment of the three phases. When individual adjustment is required, the main shaft 1 can be pulled out to separate it from the sleeve shaft 2, and the linkage and disconnection are rapid.

[0029] Embodiment 2:

[0030] The following is combined with Figure 2-4 The independent selection synchronous linkage system includes: a main shaft 1, a sleeve shaft 2, the sleeve shaft 2 is rotatably connected to a bearing seat 3, the bearing seat 3 is fixedly arranged, the sleeve shaft 2 is connected to an output transmission member 4, the main shaft 1 and the sleeve shaft 2 are concentrically arranged, the sleeve shaft 2 is provided with a plurality of sleeve shafts, and the main shaft 1 and the sleeve shaft 2 are connected and disconnected through a clutch mechanism 5;

[0031] The clutch mechanism 5 comprises a tooth groove 1 51, a tooth groove 2 52, an annular groove 53, a sleeve 1 54, a sleeve 2 55, and teeth 56. The tooth groove 1 51 is arranged outside the sleeve shaft 2, and the tooth groove 2 52 is arranged outside the main shaft 1. The main shaft 1 and the sleeve shaft 2 are connected through a bearing. An annular groove 53 is arranged on the main shaft 1 between the tooth groove 1 51 and the tooth groove 2 52. The sleeve 1 54 and the sleeve 2 55 are both provided with teeth 56. The teeth 56 of the sleeve 1 54 are kept in sliding engagement with the tooth groove 1 51, and the teeth 56 of the sleeve 2 55 can be slidably engaged with the tooth groove 2 52. When the teeth 56 of the sleeve 1 54 are completely engaged with the tooth groove 1 51, the sleeve 2 55 is located in the annular groove 53.

[0032] When it is necessary to control the adjustment of any phase separately, the teeth 56 of the control sleeve 1 54 slide on the tooth groove 1 51, and the sleeve 1 54 drives the teeth 56 of the sleeve 2 55 to slide and fit with the tooth groove 2 52. At this time, the main shaft 1 is connected with the sleeve shaft 2 through the sleeve 1 54 and the sleeve 2 55. The adjustment of the corresponding phase can be completed by controlling the rotation of the main shaft 1. The sliding sleeve 1 54 allows the teeth 56 of the sleeve 2 55 to be separated from the tooth groove 2 52, that is, the disconnection is completed, so that any phase can be adjusted independently and any phase combination can be adjusted synchronously.
