Four groups of fixed pulleys 3 are rotatably connected in the box body 1.1 in a conventional manner, the four groups of fixed pulleys 3 are uniformly distributed along the periphery of the servo motor 2, each group of fixed pulleys 3 consists of two fixed pulleys 3, one fixed pulley 3 is positioned at a corresponding position close to the servo motor 2, the other fixed pulley 3 is positioned at a corresponding position close to the edge of the box body 1.1 (namely, the center of the servo motor 2 is used as the center of a circle, and two fixed pulleys of each group of fixed pulleys are positioned on the same radius line); a perforation 4 penetrating the bottom of the box body 1.1 up and down is arranged at the bottom of the box body 1.1 and corresponds to the space between each group of fixed pulleys 3 and the servo motor 2, and the perforation 4 is used for the steel wire rope 11 to pass through.

The servo motor 2 passes through the bottom of the fixed seat 1, and then a screw rod 12 is fixedly connected to the output shaft end of the servo motor 2, a limiting piece 13 is fixedly connected to the bottom of the screw rod 12, the outer peripheral diameter of the limiting piece 13 is larger than the inner diameter of an annular sliding seat 14, and the annular sliding seat 14 is sleeved outside the screw rod 12 and is in threaded fit with the screw rod 12; a hook 15 is fixedly connected to the bottom of the limiting piece 13, and the hook 15 is used for hanging the top of tent cloth. The outer periphery of the part of the servo motor 2, which is positioned outside the fixed seat 1, is fixedly connected with an annular wire passing seat 16, and a wire passing hole is formed in the annular wire passing seat 16 and corresponds to each perforation at the bottom of the box body 1.1, and is used for the wire rope 11 to pass through.

Four top support rods 5 are hinged at equal intervals on the periphery of the box body 1.1 of the fixed seat 1, and the hinged position of each top support rod 5 corresponds to the corresponding fixed pulley block. Each top support rod 5 is also hinged with a linkage rod 17, the other end of each linkage rod 17 is hinged on the periphery of the annular sliding seat 14, the four top support rods 5 are driven to retract towards the center along with the rising of the annular sliding seat 14, and the four top support rods 5 are driven to expand outwards along with the falling of the annular sliding seat 14.
