13 upper end is fixedly connected with rotation flange 7, and rotation flange 7 is rotatably connected with mounting rack, and the setting of steering, locking mechanism is turning
Between dynamic flange 7 and mounting rack；
As shown in Figure 4 and Figure 5, steering, locking mechanism includes mounting plate 1, positioning pin 4, mounting flange 6, steel ball 11, compresses
Spring 12 and locking driving device, mounting plate 1 are fixedly connected with mounting rack, and mounting flange 6 is provided with multiple through-holes, positioning pin 4
Upper end be fixedly connected with mounting plate 1 by stop screw 8, positioning pin 4 is arranged in through-hole and can slide up and down along through-hole, turn
The upper surface of dynamic flange 7 is provided with blind hole corresponding with through-hole, and steel ball 11 is arranged in blind hole and slidably in through-hole, compresses
Spring 12 is arranged between steel ball 11 and the bottom surface of blind hole, and rotation flange 7 is rotatably connected by shaft with mounting flange 6, locks
Only driving device is fixedly connected with mounting plate 1, and positioning pin 4 is driven to move down, diameter, diameter of blind hole and the steel ball of through-hole
11 diameter is equal, and positioning pin 4 moves down the radius that stroke is steel ball 11；
When in lockup state (Fig. 4), the episphere of steel ball 11 is located in through-hole, and the lower semisphere of steel ball 11 is located at blind hole
It is interior；
When being in active state (Fig. 5), the lower end surface of positioning pin 4 is overlapped with the lower end surface of through-hole, and steel ball 11 is located at blind hole
It is interior.
