[0028] The wheel nut 2 rotates clockwise, driving the connecting cylinder 3 to move in the positive direction of the X-axis. At the same time, the spring 4 is compressed, and the connecting handle 301 drives the long connecting rod 12 to rotate counterclockwise around the first hinge point 1101. The long connecting rod 12 drives the middle connecting rod 14 to make the baffle connecting rod 16 rotate clockwise around the second hinge point 1102. The baffle connecting rod 16 rotates clockwise to drive the top support rod 13 and the arc baffle 17 to rotate clockwise around the second hinge point 1102.

[0029] This device drives the threaded rod 1 to rotate by a stepping motor 8, thereby driving the wheel nut 2 to move along the threaded rod 1. When the wheel nut 2 rotates clockwise, since one end of the spring 4 is connected to the connecting cylinder 3 and the other end of the spring 4 is connected to the top of the fixed sleeve 5, the spring 4 will be pressed against the fixed sleeve 5. At the same time, the spring 4 will be pressed, and the wheel nut 2 will push the connecting cylinder 3 toward the base disc 6. The rotation of the wheel nut 2 will simultaneously drive the connecting handle 301 to rotate clockwise, thereby driving the long connecting rod 12 to rotate around the first The hinge point 1101 rotates clockwise, and finally makes the baffle connecting rod baffle 1603 parallel to the base disc 6 to realize the closure of the device; after the line is wound up, the stepper motor 8 drives the wheel nut 2 to rotate counterclockwise, and at the same time pushes the connecting cylinder 3 to rotate counterclockwise, and the connecting handle 301 drives the long connecting rod 12 to rotate clockwise around the first hinge point 1101, and finally makes the baffle connecting rod baffle 1603 parallel to the threaded rod 1, and the inner diameter of the arc baffle 17 becomes smaller, so that the arc baffle 17 is separated from the coil.

[0030] There are multiple groups of double rocker mechanisms, which are evenly distributed on the base disc 6 along the circumferential direction; by setting up multiple groups of double rocker mechanisms and controlling the rotation of the wheel nut 2 by the stepping motor 8, the force is evenly distributed when the wire is reeled in and out, avoiding the wire being too tight or too loose due to uneven force, and through the cooperation between the wheel nut 2 and the double rocker mechanism, the reel is made more convenient and it is easy to remove the wound coil from the mechanism, reducing manpower consumption.

[0032] like Figure 6 As shown, the expansion and contraction of the device is achieved by controlling the rotation of the wheel nut 2 on the threaded rod 1. The number of rotations N can be determined by the following method:

[0033]

[0034]

[0035] Where θ1 is the angle of rotation of the baffle link 16 around the second hinge point 1102, θ3 is the angle of rotation of the long link 12 around the first hinge point 1101, and a is the distance from the connection between the baffle link 16 and the middle link 14 to the second hinge point 1102, which is m1 is the length of the baffle link vertical rod 1601, m2 is the length of the baffle link horizontal rod 1602, b is the length of the middle link 14, c is the distance from the connection between the long link 12 and the middle link 14 to the first hinge point 1101, d is the distance from the first hinge point 1101 to the second hinge point 1102, α0 is the measurement starting angle of θ1, is the measurement starting angle of θ3, d2 is the distance between the lower end point of the long connecting rod 12 and the first hinge point 1101, and P is the pitch of the threaded rod 1.
