[0023] One side of the clamping block 4 also has a flange 6, and the flange 6 and the notch 5 together form a locking structure, which is used to allow the flange 6 to extend into the notch 5 to maintain the clamping state between the base 1 and the rotating seat 2, and when the rotating seat 2 is subjected to force, the flange 6 is pushed out of the notch 5 to allow the rotating seat 2 to rotate relative to the base 1.
[0024] Based on the above technical solution, the rotatable and foldable structure includes a base 1 and a rotating seat 2 which are hinged to each other. An arc-shaped groove 3 is formed on the base 1, and a clamping block 4 is provided on the rotating seat 2, and the clamping block 4 is slidably fitted in the arc-shaped groove 3. There is also a notch 5 in the arc-shaped groove 3. The clamping block 4 has a flange 6, and the rotation of the rotating seat 2 is locked by the flange 6 being inserted into the notch 5, and the rotating seat 2 is allowed to rotate relative to the base 1 when the flange 6 is out of the notch 5. The overall structure is simple and stable, and a locking structure can be directly formed by a structure integrally formed on the base 1 and the rotating seat 2, without the need for additional components to achieve the purpose of rotation locking, so that the structure is more reliable and the production cost is lower.
[0025] In a preferred embodiment, the clamping blocks 4 are formed on two opposite outer side walls of the rotating seat 2, and the base 1 is provided with a mounting cavity 9 for inserting at least a portion of the rotating seat 2, and the two arc-shaped grooves 3 are located on the two side walls of the mounting cavity 9. Alternatively, the rotating seat 2 is provided with a cavity for inserting at least a portion of the base 1, and the two clamping blocks 4 are arranged on two opposite inner side walls in the cavity to allow the base 1 to partially extend into the rotating seat 2 and be able to flip relative to the rotating seat 2.
