When the fixed state is switched to the movable state, the key 122 is pressed down, so that the rotating part 123 rotates around the lever 1231, one end of the rotating part 123 close to the key 122 rotates towards the supporting rod 112, and one end of the rotating part 123 close to the accommodating groove 1241 moves towards the key 122. The rotation portion 123 rotates to drive the moving shaft 1233 to move toward the direction close to the key 122, since the moving shaft 1233 is engaged with the shaft hole 1244, the engaging movement of the moving shaft 1233 and the shaft hole 1244 drives the locking element 124 to move toward the direction of the key 122, the resilient member is gradually compressed, the protrusion 1243 is disengaged from the locking slot 1122, and the supporting rod 112 is rotated, and at this time, the protrusion 1243 abuts against the outer wall of the supporting rod 112, until the supporting rod 112 rotates to a position where another locking slot 1122 aligns with the protrusion 1243, the elastic member is in a compressed state, the elastic potential energy drives the locking element 124 to move into the locking slot 1122, so that the protrusion 1243 is engaged with the locking slot 1122, and the fan 1 is in a fixed state. Therefore, when the fixed state is switched to the movable state, the button 122 is pressed down, the supporting rod 112 is slightly rotated, the protrusion 1243 abuts against the outer wall of the supporting rod 112, the locking element 124 is disengaged from the locking groove 1122, the button 122 can be released, the supporting rod 112 is continuously rotated, and the protrusion 1243 can be automatically engaged with the locking groove 1122 by the elastic potential energy of the elastic element when the supporting rod 112 is rotated to a position where the other locking groove 1122 aligns with the protrusion 1243. When the fan 1 is used, the steps are simple, convenient and fast, the fan 1 can be folded, and the fan is convenient to carry and occupies a small space.

Since the locking groove 1122 is disposed on the end surface of the supporting rod 112, when the supporting rod 112 rotates to be parallel to the base 13, the locking element 124 is engaged with the locking groove 1122, and the supporting rod 112 cannot rotate any more. At this time, the fan 1 may be adjusted to be in a storage state, as shown in fig. 16, that is, the fan body 111 is rotated to make the fan body 111 parallel to the supporting rod 112, and at this time, a storage state in which the base 13, the supporting rod 112 and the fan body 111 are parallel to each other is formed, so that the occupied space is further reduced, the carrying is convenient, and the user experience is improved. Meanwhile, when the container is in the storage state, the rotating structure 1121 will be in contact with the base 13, and in order to avoid collision between the rotating structure 1121 and the base 13, a silica gel pad 1124 is disposed on one side of the rotating structure 1121, which is close to the base, as shown in fig. 15 a.
