The mounting seat 2 is used to install the protective cover 27. The slot 24 is opened on the surface of the fuselage 1. The surface of the mounting seat 2 is fixedly connected with a return spring 21. The return spring 21 is used to push the inserted block 23 that has been pushed away back to its original position, so that the inserted block 23 is inserted into the slot 24, thereby realizing the installation of the protective cover 27. The surface of the return spring 21 is fixedly connected with a connecting piece 22. The connecting piece 22 is used to connect the return spring 21 and the inserted block 23, and is also used to compress the return spring 21. The connecting piece 22 is away from the return spring 21. One side is fixedly connected with an insert block 23, which cooperates with the slot 24 to function. The insert block 23 is inserted into the slot 24 to achieve the installation of the protective cover 27. A pull rod 25 is fixedly connected to the side of the connecting piece 22 away from the insert block 23. A pull ring 26 is fixedly connected to the end of the pull rod 25 away from the connecting piece 22. The pull rod 25 and the pull ring 26 are used to pull the connecting piece 22 and the insert block 23 so that the insert block 23 is separated from the slot 24, thereby achieving the removal of the protective cover 27. A protective cover 27 is fixedly connected to the surface of the mounting base 2. The protective cover 27 is used to protect the fuselage 1 and prevent the fuselage 1 from scalding the user.

[0029] The heat dissipation mechanism includes a motor 3, an air intake grille 34 and heat dissipation holes 35. The motor 3 is arranged on the inner surface of the protective outer cover 27. The air intake grille 34 is opened on the surface of the protective outer cover 27. The air intake grille 34 is used for external cold air to enter the protective outer cover 27, thereby realizing rapid cooling of the fuselage 1. The heat dissipation holes 35 are opened on the surface of the protective outer cover 27. The heat dissipation holes 35 are used for discharging hot air inside the protective outer cover 27, thereby realizing heat dissipation of the fuselage 1. The output end of the motor 3 is movably connected with a roller 31. The motor 3 and the roller 31 are used to drive the mounting block 32 and the fan blades 33 to rotate. The end of the roller 31 away from the motor 3 is fixedly connected to the mounting block 32. The surface of the mounting block 32 is fixedly connected to the fan blades 33. The mounting block 32 and the fan blades 33 are used to draw external cold air into the protective outer cover 27 and blow out the hot air inside the protective cover 27. The motor 3 is an existing product and is not a technical protection point of this application. No further explanation will be made here.

[0030] Furthermore, the mounting seat 2 is block-shaped and is used to install the protective outer cover 27. The two ends of the return spring 21 are fixedly connected to the mounting seat 2 and the connecting piece 22 respectively. The return spring 21 is used to push the pushed-away plug-in block 23 back to its original position, so that the plug-in block 23 is inserted into the slot 24, thereby realizing the installation of the protective outer cover 27.

[0031] Furthermore, the connecting piece 22 is in the shape of a disc and is slidably connected to the mounting seat 2 via the reset spring 21 . The connecting piece 22 is used to connect the reset spring 21 and the insert 23 and is also used to compress the reset spring 21 .

[0032] Furthermore, the insert block 23 is in a state where a portion of the cylinder is cut off at an angle, and the inclined surface of the insert block 23 faces downward. The insert block 23 and the slot 24 cooperate to function, and the insert block 23 is inserted into the slot 24 to achieve the installation of the protective cover 27.

[0033] Furthermore, the insert block 23 is slidably connected to the slot 24 via the connecting piece 22 and the return spring 21 , and the slot 24 is a circular groove.

[0034] Furthermore, the pull rod 25 is cylindrical in shape, and the pull rod 25 is slidably connected to the mounting base 2. The pull rod 25 and the pull ring 26 are used to pull the connecting piece 22 and the plug block 23, so that the plug block 23 is disengaged from the slot 24, thereby realizing the disassembly of the protective cover 27. The protective cover 27 is movably connected to the fuselage 1 through the mounting base 2. The protective cover 27 is used to protect the fuselage 1 and prevent the fuselage 1 from scalding the user.

[0035] Furthermore, the roller 31 and the mounting block 32 are both cylindrical in shape. The motor 3 and the roller 31 are used to drive the mounting block 32 and the fan blades 33 to rotate. The roller 31, the mounting block 32 and the fan blades 33 are rotatably connected to the protective outer cover 27 through the motor 3. The mounting block 32 and the fan blades 33 are used to draw cold air from the outside into the protective outer cover 27, and at the same time blow out the hot air inside the protective outer cover 27. The air intake grille 34 is used to allow cold air from the outside to enter the protective outer cover 27, thereby achieving rapid cooling of the fuselage 1, and the heat dissipation holes 35 are used to discharge hot air from the inside of the protective outer cover 27, thereby achieving heat dissipation of the fuselage 1.

[0036] Working principle: Move the mounting seat 2 and the protective cover 27 down close to the fuselage 1. When the plug-in block 23 contacts the fuselage 1, it will be forced to gradually move to both sides, and finally all enter the cavity. The mounting seat 2 and the protective cover 27 can continue to move down. When the plug-in block 23 and the slot 24 are on the same horizontal line, the return spring 21 will rebound and push the plug-in block 23 into the slot 24, thereby realizing the installation of the protective cover 27. This structure can realize the disassembly of the protective cover 27. Pull the pull ring 26 and the pull rod 25 to drive the plug-in block 23 out of the slot 24 for disassembly.

[0037] The operation of the motor 3 drives the mounting block 32 and the fan blades 33 to rotate, and can draw cold air from the outside into the protective outer cover 27 through the air intake grille 34, and at the same time blow out the hot air inside the protective outer cover 27 through the heat dissipation holes 35, thereby achieving heat dissipation inside the protective outer cover 27 and quickly cooling the dynamometer.
