The adapter still includes adjustment mechanism, and adjustment mechanism sets up between fixing base 2 and joint 3 to respectively with fixing base 2 and joint 3 swing joint. The joint 3 can be driven to move in parallel towards the outer side direction or the inner side direction of the cart frame 1 relative to the fixed seat 2 through the adjusting mechanism, so that the transverse distance between the joints 3 on the left side and the right side can be adjusted.
Specifically, the adjusting mechanism includes a first connecting member 41 and a second connecting member 42, the first connecting member 41 and the second connecting member 42 are disposed at an interval in the left-right direction, one end of the first connecting member 41 is rotatably connected to the joint 3 through a first shaft 51, the other end of the first connecting member 41 is rotatably connected to the fixed seat 2 through a second shaft 52, one end of the second connecting member 42 is rotatably connected to the joint 3 through a third shaft 53, the other end of the second connecting member 42 is rotatably connected to the fixed seat 2 through a fourth shaft 54, and the first shaft 51, the second shaft 52, the third shaft 53, and the fourth shaft 54 all extend in the front-rear direction. Thus, a four-bar linkage is formed between the fixed base 2, the first connecting member 41, the joint 2 and the second connecting member 42, and when the first connecting member 41 swings left and right relative to the fixed base 2 around the second shaft 52 and the second connecting member 42 swings left and right around the fourth shaft 54, the joint 3 is driven to move left and right relative to the fixed base 2, so that the transverse distance between the joints 3 on the left and right sides is changed. The height of the joint 3 on the cart frame 1 changes to some extent while moving in the left-right direction.
In the same plane, the axial center of the first shaft 51, the axial center of the third shaft 53, the axial center of the fourth shaft 54 and the axial center of the second shaft 52 are sequentially connected to form a parallelogram structure, and a connecting line of the axial center of the first shaft 51 and the axial center of the third shaft 53, and a connecting line of the axial center of the second shaft 52 and the axial center of the fourth shaft 54 all extend along the horizontal direction.
