[0032] A base rod 141 extending into the storage groove 102 is provided on the left and right sides of the support plate 140, an arc piece 142 is fixed to the curved outer wall of the base rod 141, a positioning hole 103 is opened at the contact position between the inner wall of the storage groove 102 and the base rod 141 and the arc piece 142, and a damping shaft 104 is fixed in the positioning hole 103 at a position corresponding to the base rod 141.

[0033] Before use, manually rotate the connection disk 125 at the front end of the outer cover assembly 120 and the rear end of the fixed outer cover assembly 130 respectively, so that it drives the multiple groups of movable fan strips 124 on the outer wall to rotate synchronously, until each group of movable fan strips 124 enters the hidden groove 127 on one side and merges with the fixed fan strips 122, so that the gap between each two groups of fixed fan strips 122 is exposed, allowing air to enter the field of vision to achieve the effect of blowing and cooling, and then the fan can be used for cooling;

[0034] When it is needed to stand upright on the desktop, hold the bottom end of the jacket 110 and apply an upward external force to make the middle part of the jacket 110 wrinkle, and finally expose the surrounding support plates 140, then turn the support plates 140 one by one to rotate and make them perpendicular to the handle 100, and then pull the bottom end of the jacket 110 to restore it, thereby increasing the contact area of ​​the bottom end of the handle 100, so that it can be stably placed on the desktop, and conveniently folded and stored, making the handheld fan more convenient and beautiful when used;

[0035] When the support plate 140 rotates, the base rod 141 is driven to rotate in the positioning hole 103. When the rotation and the handle 100 are in a vertical state, the arc piece 142 just contacts the damping shaft 104, so that the support plate 140 cannot continue to rotate. In combination with the restored cover 110, the support plate 140 is stably fixed in a horizontal state, so that the fan can be stably placed on the desktop.

[0036] Please refer to Figure 1 , Figure 2 and Figure 6The upper and lower ends of the outer sleeve 110 are made of hard rubber material, and the middle part is made of soft non-slip rubber.

[0037] A switch button is provided on the outer wall of the handle 100 at the position of the soft non-slip rubber.

[0038] The large surface roughness coefficient of rubber itself is utilized to facilitate the user to hold it, and the restraining block 111 and the travel groove are used to restrain the movement of the hard rubber material, and the four groups of support plates 140 that are unfolded can be supported.

[0039] Please refer to Figure 1 A charging slot is provided at the bottom end of the handle 100 , and a sealing rubber pad is provided at the charging slot near the bottom end of the handle 100 .

[0040] The battery in the handle 100 can be charged by utilizing the charging slot, and the rubber pad blocks the intrusion of moisture and dust from the outside, thereby protecting the charging slot.

[0041] Please refer to Figure 3 and Figure 5 A circular groove 126 matching the connecting plate 125 is formed in the base plate 123 , and a rough rubber ring is inlaid on the curved inner wall of the circular groove 126 .

[0042] The outer wall of the base plate 123 is provided with a fan-shaped channel connected to the circular groove 126 , and the fan-shaped channel matches the size of the movable fan strip 124 .

[0043] The circular groove 126 is used to achieve the effect of fixed-point rotation of the base plate 123. At the same time, with the cooperation of the rough rubber ring, the base plate 123 will not rotate arbitrarily, ensuring that the movable fan strips 124 will not rotate to block the gap between the two sets of fixed fan strips 122 when the fan is used.

[0044] Please refer to Figure 2 The inner end surface of the fixed outer cover assembly 130 is a refrigeration base, and a motor is installed on the end surface of the refrigeration base. The output end of the motor is fixed with a fan blade through a connecting shaft.

[0046] When in use, before use, manually rotate the connection disk 125 at the front end of the outer cover assembly 120 and the rear end of the fixed outer cover assembly 130 respectively, so that it drives the multiple groups of movable fan strips 124 on the outer wall to rotate synchronously, until each group of movable fan strips 124 enters the hidden groove 127 on one side and merges with the fixed fan strips 122, so that the gap between each two groups of fixed fan strips 122 is exposed, allowing air to enter the field of vision to achieve the effect of blowing and cooling, and then the fan can be used for cooling;

[0047] When it is needed to stand upright on the desktop, hold the bottom end of the jacket 110 and apply an upward external force to make the middle part of the jacket 110 wrinkle, and finally expose the surrounding support plates 140, then turn the support plates 140 one by one to rotate and make them perpendicular to the handle 100, and then pull the bottom end of the jacket 110 to restore it, thereby increasing the contact area of ​​the bottom end of the handle 100, so that it can be stably placed on the desktop, and conveniently folded and stored, making the handheld fan more convenient and beautiful when used;

[0048] When the support plate 140 rotates, the base rod 141 is driven to rotate in the positioning hole 103. When the rotation and the handle 100 are in a vertical state, the arc piece 142 is in contact with the damping shaft 104, so that the support plate 140 cannot continue to rotate. In conjunction with the restored outer cover 110, the support plate 140 is stably fixed in a horizontal state, so that the fan can be stably placed on the desktop. The parts not involved in the device are the same as the prior art or can be implemented using the prior art.
