[0034] Furthermore, a power supply interface 2 and a status indicator light 3 are embedded on the surface of the device body 7 .

[0035] During use, in order to relieve the pressure of some people who have the habit of rotating objects in their hands, the extension plate 1 adopts an arc design, and a driving rod 9 is embedded inside the extension plate 1. The user can place the device in the hand and play with it, so that the device rotates in the palm of the hand. When rotating, the driving rod 9 contacts the skin and rotates. The rotation of the driving rod 9 drives the rotating shaft 12 to drive the heat dissipation blades 11 to rotate, thereby dissipating the heat of the charging unit 6 to avoid the temperature of the charging unit 6 being too high during charging, and the heat dissipation cavity 10 is connected with the heat dissipation groove 4 to facilitate the circulation and heat dissipation of gas, and the setting of the heat dissipation blades 11 can dissipate heat from the palm of the hand when the user plays with it, avoiding the influence of sweat on the skin surface on the device.

[0036] Embodiment 2

[0037] Based on the first embodiment, Figure 1-6 As shown, a rotating groove 16 is opened inside the device body 7, and a partition grid 13 is provided between the rotating groove 16 and the heat dissipation cavity 10 for separation. A driving ring 15 and a one-way turntable 17 are rotatably connected inside the rotating groove 16, and the one-way turntable 17 rotates coaxially with the rotating shaft 12.

[0038] like Figure 1-6 As shown, a worm groove 14 is provided in the middle of the driving rotating rod 9 , and a helical tooth groove 18 meshing with the worm groove 14 is provided on the side end surface of the driving ring 15 .

[0039] When in use, when the driving rod 9 rotates, the driving ring 15 will be driven to rotate synchronously under the action of the worm groove 14 and the bevel tooth groove 18, and the rotation of the driving ring 15 will drive the one-way turntable 17 to rotate, thereby controlling the rotation of the heat dissipation blades 11 to achieve the heat dissipation effect.

[0040] like Figure 1-6 As shown, the inner wall of the driving ring 15 is fixedly connected with a ramp block 19, the one-way turntable 17 is provided with a snap-fit ​​groove 22, an elastic rotating shaft 23 is provided inside the snap-fit ​​groove 22, the elastic rotating shaft 23 is fixedly connected with a snap-fit ​​claw 20 adapted to the ramp block 19, the snap-fit ​​claw 20 is elastically fitted with the ramp block 19, and the cross-section of the ramp block 19 is triangular.

[0041] When in use, in order to avoid invalid work generated by the reciprocating rotation of the heat dissipation blades 11, a snap-on claw 20 and a ramp block 19 are provided. When the snap-on claw 20 and the ramp block 19 are engaged, the drive ring 15 can drive the one-way turntable 17 to rotate in one direction. If the drive ring 15 rotates in the opposite direction, the inclined surface of the ramp block 19 will fit with the snap-on claw 20, and thus cannot be engaged with the snap-on claw 20. At this time, the one-way turntable 17 will not be driven to rotate. When the ramp block 19 and the snap-on claw 20 are not engaged, the regular spring sound generated by the snap-on claw 20 and the ramp block 19 under the elastic force of the elastic shaft 23 also helps to reduce the pressure on the user.

[0042] like Figure 1-7As shown, one end of the one-way turntable 17 away from the rotating shaft 12 is fixedly connected to the power ring 21, the device body 7 is provided with an energy storage module, and the power ring 21 is electrically connected to the energy storage module.

[0043] like Figure 1-7 As shown, the power ring 21 includes a stator 24, an air gap 25 and an electromagnetic rotor 26. The stator 24 is fixedly connected to the one-way turntable 17. The air gap 25 is opened inside the stator 24. The electromagnetic rotor 26 is rotatably arranged in the middle of the air gap 25, and the rotating shaft 12 passes through the one-way turntable 17 and is connected to the electromagnetic rotor 26.

[0044] When in use, by connecting the rotating shaft 12 with the power ring 21, the rotating shaft 12 can be driven by the driving rod 9, and the electromagnetic rotor 26 can be driven to rotate by the rotation of the rotating shaft 12. Under the action of the stator 24, the device body 7 can be powered by electromagnetic induction, thereby reducing the energy loss of the device body 7. Furthermore, when the outdoor device body 7 is insufficient in power, it can also be powered by the rotation of the driving rod 9, which greatly improves the functionality of the device for outdoor use. The power ring 21 is electrically connected to the energy storage device, and can also be powered by the device body 7 to drive the rotating shaft 12 to rotate for active heat dissipation, thereby ensuring the temperature control of the device and the unit to be charged 6 during charging.

[0045] like Figure 1-6 As shown in 8-10, the driving rod 9 includes a driving rod body 27, a first elastic member 28, a rotating shaft 29 and an anti-slip layer 30. The driving rod body 27 is rotatably embedded in the interior of the extension plate 1 through the rotating shaft 29. The first elastic member 28 is elastically connected to the rotating shaft 29. The anti-slip layer 30 is fixedly connected to both ends of the side end surface of the driving rod 9, and the device body 7 is extended with a guard plate 8 adapted to the worm groove 14.

[0046] like Figure 1-6 As shown in FIGS. 8-10 , a first sliding groove 32 adapted to the rotating shaft 29 is provided inside the extension plate 1 , and a limiting layer 31 fitted to the driving rod body 27 is provided at one end of the first sliding groove 32 .

[0047] During use, in order to avoid the electric ring 21 driving the rotating shaft 12 to rotate and drive the driving rod 9 to rotate, causing certain safety hazards, the driving rod body 27 is elastically arranged inside the first sliding groove 32 through the first elastic member 28. When the driving rod 9 is squeezed by external force, the worm groove 14 engages with the helical tooth groove 18. When there is no force, the driving rod body 27 is in contact with the limiting layer 31 under the action of the first elastic member 28. The limiting layer 31 can be made of rubber material to limit the driving rod body 27 under the action of friction.

[0048] like Figure 1-6As shown in 10-11, the clamping mechanism 5 includes a clamping plate 33, a buffer sheet 34, a limiting protrusion 35, a second sliding groove 36 and a second elastic member 37. The second sliding groove 36 is embedded in the interior of the device body 7, and the second elastic member 37 is installed in the interior of the second sliding groove 36. The clamping plate 33 is elastically connected to the second sliding groove 36 through the second elastic member 37. The buffer sheet 34 is fixedly adhered to one end of the clamping plate 33, and the limiting protrusion 35 is embedded in the end of the buffer sheet 34 away from the clamping plate 33.

[0049] Furthermore, two groups of clamping plates 33 are provided, one group of clamping plates 33 is elastically connected to the second sliding groove 36 , and the other group of clamping plates 33 is fixedly connected to the front end surface of the device body 7 .

[0050] When in use, the clamping plate 33 is elastically arranged inside the second sliding groove 36 through the second elastic member 37. The charging unit 6 can be effectively clamped and fixed by the clamping plate 33, and the clamping plate 33 is fitted with a buffer plate 34 and a limiting protrusion 35, which improves the fixing effect while further reducing the damage to the charging unit 6.

[0051] Working principle: In order to relieve the pressure, some people have the habit of rotating objects in their hands. The extension plate 1 adopts an arc design, and a driving rod 9 is embedded inside the extension plate 1. The user can put the device in the hand to play with it, so that the device rotates in the palm of the hand. When rotating, the driving rod 9 contacts the skin and rotates. The rotation shaft 12 drives the heat dissipation blades 11 to rotate through the rotation of the driving rod 9, so as to dissipate the heat of the to-be-charged unit 6 to avoid the over-high temperature of the to-be-charged unit 6 when charging. The heat dissipation cavity 10 is connected with the heat dissipation groove 4 to facilitate the circulation and heat dissipation of the gas. The setting of the heat dissipation blades 11 can dissipate the heat from the palm of the hand when the user is playing with it, so as to avoid the influence of sweat on the skin surface on the device. When the driving rod 9 rotates, the belt is driven under the action of the worm groove 14 and the bevel tooth groove 18. The one-way turntable 17 is driven to rotate by the rotation of the drive ring 15, thereby controlling the rotation of the heat dissipation blades 11 to achieve the effect of heat dissipation. In order to avoid the reciprocating rotation of the heat dissipation blades 11 to generate invalid work, a buckle claw 20 and a ramp block 19 are provided. When the buckle claw 20 and the ramp block 19 are engaged, the drive ring 15 can drive the one-way turntable 17 to rotate in one direction. If the drive ring 15 rotates in the opposite direction, the inclined surface of the ramp block 19 fits with the buckle claw 20, so that it cannot be engaged with the buckle claw 20. At this time, the one-way turntable 17 will not be driven to rotate. When the ramp block 19 and the buckle claw 20 are not engaged, the regular shrapnel sound generated by the buckle claw 20 and the ramp block 19 under the elastic force of the elastic shaft 23 also helps the user to The electric ring 21 is connected to the rotating shaft 12 to reduce pressure. The rotating shaft 12 can be driven by the driving rod 9, and the electromagnetic rotor 26 can be driven to rotate by the rotation of the rotating shaft 12. Under the action of the stator 24, the device body 7 can be supplemented with electricity by electromagnetic induction, thereby reducing the energy loss of the device body 7. Furthermore, when the power of the outdoor device body 7 is insufficient, the power can also be supplemented by the rotation of the driving rod 9, which greatly improves the functionality of the device for outdoor use. The electric ring 21 is electrically connected to the energy storage device, and the electric ring 21 can also be powered by the device body 7 to drive the rotating shaft 12 to rotate for active heat dissipation, thereby ensuring the temperature control of the device and the unit to be charged 6 during charging. In order to avoid the electric ring 21 driving the rotating shaft 12 to rotate and drive the driving unit 6 to rotate, the electric ring 21 can be connected to the rotating shaft 12 to rotate and drive the driving unit 6 to rotate. The rotation of the rotating rod 9 causes certain safety hazards, so the driving rod body 27 is elastically arranged inside the first sliding groove 32 through the first elastic member 28. When the driving rotating rod 9 is squeezed by external force, the worm groove 14 engages with the helical tooth groove 18. When there is no force, the driving rod body 27 is fitted with the limiting layer 31 under the action of the first elastic member 28. The limiting layer 31 can be made of rubber material, and the driving rod body 27 is limited under the action of friction. The clamping plate 33 is elastically arranged inside the second sliding groove 36 through the second elastic member 37. The charging unit 6 can be effectively clamped and fixed by the clamping plate 33, and the clamping plate 33 is fitted with a buffer sheet 34 and a limiting protrusion 35, which improves the fixing effect while further reducing the damage to the charging unit 6.
