[0041] Similarly, when the connecting line 5 needs to be stored, the unlocking assembly is manually pushed to push the arc-shaped card plate 14 along the length direction of the ejection slide groove 13 to squeeze the ejection spring 15 to produce a contraction deformation, and at the same time, one end of the arc-shaped card plate 14 is disengaged from the inside of the clamping groove 16 to release the clamping fixation of the arc-shaped card plate 14 and the circular card plate 12, and then the storage spring 10 is released from the force and produces a rebound deformation, so that the storage spring 10 pushes the guide slider 8 to drive the guide roller 9 to push the connecting line 5 to move along the length direction of the guide slide groove 4, and at the same time, the two adjacent guide sliders 8 drive the guide rollers 9 to push the connecting line 5 to form a curved S shape inside the storage box 1, so that one end of the connecting line 5 is pulled by the guide roller 9 and bent and stored inside the storage box 1, thereby facilitating the automatic storage of the connecting line 5, effectively improving the storage efficiency and portability of the device.

[0042] Reference Figure 3 - Figure 5 The unlocking assembly includes an unlocking slot 17 symmetrically opened at one end of the storage box 1, one end of the unlocking slot 17 is connected to the ejection slot 13, and a U-shaped unlocking rod 18 is slidably connected inside the two adjacent unlocking slots 17, and an oblique socket adapted to the U-shaped unlocking rod 18 is opened at one end of the arc-shaped clamping plate 14.

[0043] When in use, the U-shaped unlocking rod 18 is manually pushed to move along the length direction of the unlocking slot 17, so that one end of the U-shaped unlocking rod 18 is inserted into the inclined socket, and the arc-shaped clamping plate 14 is pushed along the length direction of the ejection slot 13 to squeeze the ejection spring 15, so that the arc-shaped clamping plate 14 is disengaged from the inside of the clamping slot 16 along the length direction of the ejection slot 13, thereby facilitating the quick release of the clamping fixation between the arc-shaped clamping plate 14 and the circular clamping plate 12, further improving the portability of the device.

[0044] Reference Figure 1 and Figure 2 A plurality of limit slide bars 19 are symmetrically and evenly fixedly connected inside the storage box 1 , the guide slider 8 is slidably connected to the limit slide bar 19 , and the storage spring 10 is sleeved on one end of the limit slide bar 19 .

[0045] When in use, when one end of the traction connecting line 5 passes around the guide roller 9 and pushes the guide roller 9 to drive the guide slider 8 to squeeze the storage spring 10 along the length direction of the guide slide groove 4, the storage spring 10 moves along the guiding direction of the limiting slide bar 19, thereby facilitating the support and guidance of the storage spring 10, reducing the bending of the storage spring 10 and improving the practicability of the device.

[0046] Reference Figure 2 and Figure 6 One end of the guide roller 9 is rotatably sleeved with a roller sleeve 20 , and the roller sleeve 20 rolls against the connecting line 5 .

[0049] Among them, one end of the heat conducting plate 27 is evenly and fixedly connected with a plurality of heat dissipating fins 28;

[0050] Furthermore, a filter screen 29 is fixedly connected to the interior of the air inlet 23 .

[0051] When in use, firstly, the heat conducting plate 27 is set to conduct the working heat of the control main board 2, and when the control main board 2 is working, the heat dissipation motor 26 is started to drive the bevel gear 25 to rotate, and at the same time, the bevel gear 25 is meshed with the bevel gear 1 24, and the bevel gear 1 24 is driven to drive the fan blade 22 to rotate, so that the fan blade 22 rotates to draw air through the air inlet 23 into the exhaust slot 21, and then blows to the surface of the heat conducting plate 27 through the output end of the exhaust slot 21, and when the air contacts the surface of the heat conducting plate 27, contact heat exchange is formed with the surface of the heat conducting plate 27, so as to quickly reduce the surface temperature of the heat conducting plate 27 and the control main board 2, maintain the working state of the control main board 2, and extend the service life of the control main board 2;

[0052] At the same time, when the fan blades 22 draw the air through the air inlet 23 and into the exhaust slot 21, the air is filtered and intercepted by the filter 29 to reduce the dust from entering the exhaust slot 21 and affecting the working efficiency of the fan blades 22. When the fan blades 22 accelerate the air to blow toward the surface of the heat conduction plate 27, the heat dissipation fins 28 are arranged to increase the surface area of ​​the heat conduction plate 27, thereby improving the heat exchange efficiency between the air and the surface of the heat conduction plate 27, thereby improving the heat dissipation efficiency of the device.
