On the other hand, in order to facilitate the support member 201 to be smoothly separated from the translation member 302b after being fastened (mainly, the first rotation gears 201a-14, the second rotation gears 201a-24, the first linear racks 302b-11 and the second linear racks 302b-21 are separated), the first racks 302b-1 and the second racks 302b-2 are connected into a whole through the concave rack 302b-4, meanwhile, the concave rack 302b-4 is provided with the offset gears 302b-41, the offset gears 302b-41 are perpendicular to the first racks 302b-1 in spatial position, the offset gears 302b-41 and the fourth rotation gears 302a-3 simultaneously have a certain distance d on the same plane, and the length of the distance d is the movement distance of the translation racks 302b-3, namely, after the concave rack 302b-4 performs linear movement with the first racks 302b-1 and the distance d (through connection) The third rotating shaft 302a-1 rotates theta 1), then the dislocated gear 302b-41 is attached to the fourth rotating gear 302a-3, at this time, the third rotating shaft 302a-1 is further rotated to rotate theta 2, at this time, because the first rack 302b-1 and the second rack 302b-2 are in spherical connection with the translational rack 302b-3, under the driving of the dislocated gear 302b-41, the first rack 302b-1 and the second rack 302b-2 and the translational rack 302b-3 will dislocate (move transversely), i.e. the first rotating gear 201a-14, the second rotating gear 201a-24, the first linear rack 302b-11 and the second linear rack 302b-21 are separated, at this time, because the fifth rotating gear 302a-4 is a partial gear, therefore, when the third rotating shaft 302a-1 rotates by θ 2, the translational rack 302b-3 does not move, and only the dislocation motion occurs, as shown in fig. 7 to 9, the fourth rotating gear 302a-3 is also a partial gear, and only the meshing rotation of θ 2 can occur during one rotation.
The adjusting member 302 further includes a limiting member 302d, the limiting member 302d is disposed in the first housing 301 and includes a limiting rod 302d-1, a second switching gear 302d-2 and a sliding groove 302d-3 fixedly connected to the first housing 301, one side of the limiting rod 302d-1 is embedded in the sliding groove 302d-3, the other side is provided with a third linear rack 302d-11, and the second switching gear 302d-2 is respectively engaged with the third rotating gear 302a-2 and the third linear rack 302 d-11; one end of the limiting rod 302d-1 is connected with a third spring 302d-4, the other ends of the two ends of the third spring 302d-4 are connected with the first shell 301, and the other end of the limiting rod 302d-1 extends into a limiting groove 202b-2 on the slide rail 202 b.
After the above steps are implemented, that is, after the third rotating shaft 302a-1 rotates (θ 1+ θ 2), the sliding rail 202b needs to drive the supporting plate 201c to move, for example, a limiting member 302d shown in fig. 9 is disposed in the inner side wall of the first housing 301, and includes a limiting rod 302d-1 disposed on the other side of the third rotating shaft 302a-1, one end of the limiting rod 302d-1 is embedded in a sliding groove 302d-3 fixedly connected to the first housing 301, and the other end is provided with a third linear rack 302d-11 engaged with the second converting gear 302d-2, it should be noted that the other side of the second converting gear 302d-2 is engaged with the third rotating gear 302a-2, and since the third rotating gear 302a-2 is a partial gear, after the third rotating shaft 302a-1 rotates (θ 1+ θ 2), the third converting gear 302d-2 is engaged with the second converting gear 302d-2 to generate the rotation of θ 3 The angle (at this time, the structure rotating at the positions of theta 1 and theta 2 will not rotate, because both are local gears), at this time, the limiting rod 302d-1 will be driven to separate from the limiting groove 202b-2 on the sliding rail 202, at this time, the sliding rail 202b will not be restrained, the second spring 202c moves under the elastic force to drive the supporting plate 201c to move together, so that the limiting rod 302d-1 can return, a third spring 302d-4 is arranged at one end part of the limiting rod 302d-1 far away from the supporting plate 201c, the third spring 302d-4 is a pressure spring, when necessary (i.e. the slide rail 202b needs to be limited), the limiting rod 302d-1 is pushed into the limiting groove 202b-2, when the slide rail 202b needs to be separated, the third rotating shaft 302a-1 is rotated to rotate by theta 3.
Therefore, as shown in fig. 10, for the third rotating shaft 302a-1, three motion transformations mainly occur, when the rotation angle of θ 1 occurs, the connection transformation of the connecting buckle 201a is mainly achieved, then the rotation of θ 2 occurs by continuing the rotation, so that the dislocation motion occurs, that is, the first rotating gears 201a-14, the second rotating gears 201a-24, the first linear racks 302b-11 and the second linear racks 302b-21 are separated, and finally the rotation of θ 3 occurs, the motion of the limiting rod 302d-1 occurs, and the limitation on the sliding rail 202b is removed.
The transmission member 303 is perpendicular to the rotating member 302a, and a first bevel gear 303a is disposed at each end of the transmission member 303, and the bevel gears 303a are engaged with second bevel gears 302a-5 disposed on the rotating member 302 a.
