This application does not specifically limit the number of ring buckles 30 , as long as the inner ring structure 1 and the outer ring structure 2 can be assembled with the collimator 5 through the mounting structure 3 .

In one embodiment, as shown in FIGS. 2 to 4 , the legged collimator 5 includes at least one connecting portion 50 , and the inner ring structure 1 includes at least one limiting block 10 and at least one connecting portion 50 adapted to the at least one connecting portion 50 . There is a reserved groove 9, the connecting part 50 is used to insert into the reserved groove 9, and the limiting block 10 is used to limit the movement between the outer ring structure 2 and the inner ring structure 1.

For example, the limit block 10 may be a limit switch, or may be a screw installed on the inner ring structure 1 or a protrusion welded on the inner ring structure 1 . The limiting block 10 is used to limit the maximum movement position of the outer ring structure 2 relative to the inner ring structure 1 .

The movement occurs relative to the inner ring structure 1 so that the reserved groove 9 can be opened to the outside to form a space sufficient to accommodate the connecting portion 50. Then, the connecting portion 50 of the legged collimator 5 can be inserted into the reserved groove 9, thereby The footed collimator 5 can be placed in the inner ring structure 2, and then the outer ring structure 2 or the ring buckle 30 can be rotated or moved in a direction opposite to the predetermined direction. At this time, the ring buckle 30 can drive the footed collimator. The connecting part 50 of the collimator 5 moves until the connecting part 50 of the legged collimator 5 abuts one side of the groove wall of the reserved groove 9 . Preferably, in order to allow the reserved groove 9 to be opened to the outside to form a space sufficient to accommodate the connecting portion 50, and to keep the movement of the outer ring structure 2 relative to the inner ring structure 1 in a better controllable state, at this time, a fixed position is provided on the inner ring. The limit block 10 on the structure 1 can contact the outer ring structure 1 or the ring buckle 30, so that the maximum movement amplitude of the outer ring structure 1 and the space volume of the reserved slot 9 can be set to facilitate the operation of the operator.

In one embodiment, as shown in FIGS. 3 and 4 , the connection assembly 6 further includes at least one positioning post 8 , which cooperates with the inner ring structure 1 to limit the movement of the outer ring structure 2 relative to the inner ring structure 1 .

For example, the number of positioning posts 8 can be set to one or more. The shape of the positioning post 8 may be circular, elliptical or polygonal. This application does not specifically limit the shape and number of the positioning posts 8 , as long as the positioning posts 8 can cooperate with the inner ring structure 1 to limit the movement of the outer ring structure 2 relative to the inner ring structure 1 .

Specifically, the outer ring structure 2 and the inner ring structure 1 cooperate with each other, close and press the three connecting parts 50 of the footed collimator 5, thereby connecting the footed collimator 5 with the inner ring structure 1 and the outer ring. Structure 2 is fixedly installed. By pressing the positioning post 8 on the inner ring structure 1, the movement of the outer ring structure 2 relative to the inner ring structure 1 can be limited, thereby further locking and fixing the legged collimator 5. When it is necessary to rotate the outer ring structure 2, only the positioning post 8 needs to be pulled up to release the movement limit. In other words, before the footed collimator 5 is installed or removed, the positioning post 8 can be pulled up so that the outer ring structure 2 and the inner ring structure 1 are in a state of relative movement. When the footed collimator 5 is installed, the positioning post 8 can be inserted so that the outer ring structure 2 and the inner ring structure 1 are in a locked state.

The connection assembly 6 provided in the embodiment of the present application uses the positioning post 8 to cooperate with the inner ring structure 1 to limit the movement of the outer ring structure 2 relative to the inner ring structure 1, thereby fixing the relative positions of the outer ring structure 2 and the inner ring structure 1. This avoids instability of the connection component 6 due to relative position deviation.
