[0037] Refer to Figure 2 , Threaded grooves are respectively opened on the upper and lower sides of the left part of the fan handle 2. Two threaded posts 8 are penetrated and fixed on the inner wall of the right part of the fan main body 1. The threaded openings on the upper and lower sides of the threaded posts 8 correspond to the threaded grooves. During installation, the fan handle 2 is inserted along the right part of the fan main body 1 until the threaded posts 8 correspond to the threaded grooves. At this time, a bolt 7 is screwed into the threaded post 8 to fix between the fan main body 1 and the fan handle 2.

[0038] Refer to Figure 2 , A circuit board 9 is fixedly connected to the inner wall of the right part of the fan main body 1. The circuit board 9 is electrically connected to the electric motor inside the fan main body 1. Two positive and negative power supply elastic sheets 10 are fixedly connected to the inner wall of the right side of the fan main body 1 by screws. The left part of the power supply elastic sheet 10 is electrically connected to the circuit board 9. The power supply elastic sheet 10 is a male power supply elastic sheet, and its surface is gold-plated to prevent surface oxidation after long-term use and affect the contact effect.

[0039] Refer to Figure 2 And Figure 4 , The battery accessory 3 includes two batteries 13. A battery connection board 12 is fixedly connected to the inner wall of the left part of the battery accessory 3. The right side wall of the battery connection board 12 is respectively in contact with the positive electrode of a group of batteries 13 and the negative electrode of a group of batteries 13, so as to realize the power supply of the battery accessory 3 to the fan main body 1. A battery elastic sheet female seat 11 is fixedly connected to the left side wall of the battery connection board 12 by SMT patch method. The right part of the power supply elastic sheet 10 is in contact with the battery elastic sheet female seat 11. When they are in contact, the battery 13 supplies power to the fan main body 1, and the rotation of the turbine fan is driven by the electric motor. A chamfer 101 is provided at the bottom end of the power supply elastic sheet 10. The chamfer 101 is in an inverted trapezoid shape, which is convenient for the insertion of the battery elastic sheet female seat 11. A bending part 111 is provided at the top of the battery elastic sheet female seat 11. The bending part 111 is bent inward, and there are gaps at both ends of the opening, not in contact with each other, which is convenient for the access of the power supply elastic sheet 10. A power supply interface 5 is opened on the left side wall of the battery accessory 3. The power supply elastic sheet 10 passes through the power supply interface 5 and is connected to the battery elastic sheet female seat 11. A charging interface 4 is provided on the front side of the battery accessory 3 for charging the battery accessory 3.

[0040] Refer to Figure 3, the limiting mechanism 6 includes a button 61 which penetrates and slides on the inner wall of the right part of the fan main body 1. A through hole is provided in the right part of the fan main body 1 for guiding the button 61. A clamping block 62 is fixedly connected to the right side wall of the button 61. The clamping block 62 penetrates and is slidably connected to the inner wall of the right part of the fan main body 1. The right part of the clamping block 62 protrudes upward, and the right side wall of the clamping block 62 is inclined. By squeezing its inclined surface, it can move vertically downward. The bottom of the clamping block 62 is elastically connected to the inner wall of the fan main body 1 through an elastic member. The elastic member includes a return spring 64. The two ends of the return spring 64 are respectively fixedly connected to the bottom end of the button 61 and the inner wall of the fan main body 1. Through the elasticity of the return spring 64, the button 61 can always maintain a state of being pushed upward without being affected by external forces. A clamping groove 63 is provided on the left part of the battery accessory 3, and they are clamped with each other. By the inner wall of the clamping groove 63 squeezing the inclined surface of the button 61, it moves downward. Correspondingly, a through groove is provided on the top surface of the fan handle 2. When the fan handle 2 is installed, the button 61 needs to be pressed downward first. After the fan handle 2 is completely pushed in, the button 61 will pass through the through groove and reset by the elastic force of the return spring 64.

[0041] Working principle: When the battery accessory 3 needs to be replaced, by pressing the button 61 downward, the button 61 drives the clamping block 62 to move downward, and when its protruding part moves to a position where it can completely pass through the clamping groove 63, the entire battery accessory 3 can be taken out at this time. When replacing with a new battery accessory 3, only by inserting the battery accessory 3 along the right part of the fan handle 2, the clamping groove 63 will squeeze the right inclined surface of the clamping block 62, so that it moves downward. When passing through the clamping groove 63, it will be reset by the elastic force of the return spring 64 to clamp and fix the battery accessory 3.
