[0031] Reference Figure 2 and Figure 3 , both sides of the charging head 101 are fixedly connected with mounting blocks 409, the inner cavity of the mounting block 409 is provided with a second dovetail groove 411, the inner cavity of the second dovetail groove 411 is movably connected with a second dovetail block 412, the inner side of the second dovetail block 412 is fixedly connected to the inner side of the shell 401, and the second dovetail groove 411 and the second dovetail block 412 are arranged so that the shell 401 plays a guiding role when it is sleeved on the surface of the charging head 101, and will not cause positional deviation, so that the positions of the two are convenient to fix;

[0032] Reference Figure 3 and Figure 4 The surface of the fixed column 408 is provided with a spring 402, and the number of the springs 402 is four. One end of the spring 402 is fixedly connected to one side of the rotating column 407, and the other end of the spring 402 is fixedly connected to the inner wall of the mounting groove 403. By setting the spring 402, the rotating column 407 can always generate an inward force on the clamping rod 405 without being subjected to external force, so that the clamping rod 405 is always clamped to the clamping groove 404;

[0033] Reference Figure 3 and Figure 4 , a snap-in groove 404 is provided on the surface of the inclined surface block 406, and the shape of the snap-in groove 404 is consistent with the shape of the top of the snap-in rod 405.

Through the setting of the snap-in groove 404, the snap-in rod 405 can be snapped into the inside of the snap-in groove 404. Since the inclined surface block 406 is fixedly connected to the charging head 101, the position of the charging head 101 and the shell 401 can also be fixed. Since the inner cavity of the snap-in groove 404 is arc-shaped, when the shell 401 moves upward, the snap-in rod 405 can be detached from the inner cavity of the snap-in groove 404 through the arc surface of the snap-in groove 404, thereby detaching the charging head 101 from the shell 401;

[0034] Reference Figure 3 A guide groove 410 is provided on one side of the shell 401. The diameter of the guide groove 410 is consistent with the diameter of the connecting wire 102. The inner cavity of the guide groove 410 is movably connected to the surface of the connecting wire 102. Through the setting of the guide groove 410, since the diameter of the guide groove 410 is consistent with the connecting wire 102, when the shell 401 is inserted around the charging head 101, the connecting wire 102 can slide on the surface of the guide groove 410 without affecting the downward movement of the shell 401 until the shell 401 completely wraps the surface of the charging head 101;

[0035] Reference Figure 5 and Figure 6 , the bottom of the mounting chamber 201 is fixedly connected with an air guide plate 205, which is arranged in an inclined surface.

The support bar 202 is arranged to support the position of the motor 203;

[0036] Reference Figure 1 and Figure 7When the cam 310 is in the closed position, the cam 310 will be in the closed position, so the cam 310 will be in the open position when the cam 310 is in the closed position.

[0037] Reference Figure 7 The top of the limit block 306 is fixedly connected to the first dovetail block 303, and the bottom of the fixing bar 301 is provided with a first dovetail groove 302. The inner cavity of the first dovetail groove 302 is movably connected to the surface of the first dovetail block 303. The first dovetail groove 302 and the first dovetail block 303 are arranged to guide and limit the limit block 306, so that the limit block 306 will not separate from the fixing bar 301 when sliding in the inner cavity of the fixing bar 301, thereby improving the stability of the limit block 306 when sliding.

[0038] Working principle: When the charging head 101 needs to be cooled, the shell 401 is placed on the surface of the charging head 101, and the second dovetail block 412 slides downward along the inner cavity of the second dovetail groove 411. At the same time, the top of the clamping rod 405 slides to the inner cavity of the clamping groove 404 through the inclined surface of the inclined block 406, so that the clamping rod 405 and the inclined block 406 are clamped, thereby fixing the position of the charging head 101 and the shell 401. Then the motor 203 starts to work, and the output end of the motor 203 drives the bracket 206 to rotate. The wind generated by the rotation of the bracket 206 is driven by the wind deflector 2 05 is guided into the gap between the shell 401 and the charging head 101, thereby cooling the charging head 101. At this time, the twisting block 304 is twisted, and the limit block 306 is moved inward through the threaded connection between the twisting block 304 and the limit block 306, so that the inner cavity of the limit block 306 contacts the surface of the connecting line 102. When it is necessary to separate the shell 401, the twisting block 304 is twisted to disengage the limit block 306 from the close contact with the connecting line 102, and then the shell 401 is moved upward to disengage the clamping rod 405 from the clamping of the inner cavity of the inclined block 406, thereby separating the shell 401 from the charging head 101.
