It should be noted that the arc grooves 203a-1 are uniformly distributed on the disk 203a in an array and connected with the brackets 202 uniformly distributed around the support plate 201.

The arc groove 203a-1 has a distance from the proximal end a to the center of the disc 203a that is less than the distance from the distal end B to the center of the disc 203 a.

The radial rod 203B can move along the length direction of the radial groove 201g, that is, the radial rod 203B can move linearly along the radial direction of the disc 203a, when the radial rod 203B works on the center of the disc 203a, the insertion shaft 203c approaches from the proximal end a to the distal end B, and simultaneously drives the disc 203a to rotate, so that the insertion shafts 203c of the other arc grooves 203a-1 generate synchronous motion, and the supports 202 are opened or closed synchronously.

Example 2

Referring to fig. 1 to 7, the difference between the present embodiment and the previous embodiment is that a first hook 202a is disposed at an end of the support 202, and the first hook 202a is hooked on the first hanging rod 201 d; a second hook 203d is arranged at the end part of the radial rod 203b, a second hanging rod 202b is arranged on the side surface of the bracket 202, and two ends of the second hanging rod 202b are connected with the bracket 202 through side plates 202 c; the bracket 202 is further provided with a yielding groove 202d, and the second hook 203d is hooked on the second hanging rod 202 b.

The end of the disc 203a is provided with a ratchet shaft 203a-2, the bottom of the circular groove 201f is provided with a central groove 201f-1, and the ratchet shaft 203a-2 is arranged in the central groove 201 f-1.

The side surface of the central groove 201f-1 is provided with a side groove 201f-2, a baffle 201f-3 is arranged in the side groove 201f-2, and the baffle 201f-3 is connected with the bottom of the side groove 201f-2 through a second spring 201 f-4;

the bottom of the side groove 201f-2 is also provided with an electromagnet 201f-5, and the end part of the baffle 201f-3 is made of magnetic materials.

In this embodiment, a specific detachable scheme of the bracket 202 is provided, and in an initial state, the first spring 201e has a pulling force on the first hanging rod 201d, and pulls the first hanging rod 201d into the recessed groove 201b, specifically, in a using process, the first hanging rod 201d is pulled out from the recessed groove 201b first, the first hook of the bracket 202 is hooked on the first hanging rod 201d, at this time, the bracket 202 is primarily fixed, after the second hanging rods 202b of all the brackets 202 are hooked on the second hook 203d, a pulled-out state of the first hanging rod 201d is maintained, at this time, the bracket 202 is rotated by using the first hanging rod as a rotation axis, and the second hanging rod 202b is hooked in the second hook 203d, it should be noted that an opening of the second hook 203d faces an opening of the insertion groove 201a, that is, a direction shown in fig. 3, and in an actual use, the direction is a downward direction.

When the second hanging rod 202b is hooked on the second hook 203d, the second hook 203d has a downward force on the second hanging rod 202b, and the first hanging rod 201d has an upward force on the first hook 202a, so that the support 202 is fixed and a balanced state is achieved.

On this basis, the brackets 202 are pulled in a direction away from the center of the supporting plate 201 (i.e., pulled rightward in fig. 3), so that the opening angle thereof is increased, and then the second hooks 203d are pulled into the insertion grooves 201a, that is, the insertion shafts 203c approach from the proximal end a to the distal end B, and drive the brackets 202 to open outward synchronously.

The matching structure of the ratchet shaft 203a-2 and the baffle 201f-3 ensures that the bracket 202 can be only broken outwards to enlarge the opening angle and can be subjected to the resistance of the ratchet inwards when the bracket 202 is controlled from the outside, and when the bracket is required to be retracted, the electromagnet 201f-5 is opened to suck the baffle 201f-3 back into the side groove 201f-2, and the bracket 202 is retracted towards the middle.
