the second link middle portion is rotatably connected to the base;
the other end of the second connecting rod is rotatably connected with the hydraulic cylinder;
the liquid cylinder is rotatably connected with the base body;
the sliding groove is connected with the locking block in a sliding manner;
the sliding groove is connected with the base body.
The base body further includes:
a first support base;
a second support seat;
the second connecting rod middle part is rotatably connected with the first supporting seat;
the hydraulic cylinder is rotatably connected with the second supporting seat.
Due to the adoption of the technical scheme, the invention has the beneficial effects that:
the locking piece can prevent simultaneously that the carousel from rotating along two anticlockwise directions, avoids the carousel to rotate along not needing the direction, has avoided the safety risk, can carry out automatic control, has reached reduce cost, the purpose of raising the efficiency.
