[0005] A second fold is also provided on the protective shell, and a distance d between the first fold and the second fold is not less than a height h of the protective shell.

[0006] A first magnet is provided on the top surface of the cover plate at the position of the through hole, and a second magnet is provided on the bottom of the protective shell, and the first magnet cooperates with the second magnet.

[0007] A protective layer is arranged inside the protective shell, and the protective layer is made of foam material.

[0008] The protective shell and extension shell are both made of silicone.

[0009] The extension shell is filled with foam padding.

[0010] The height of the protective shell is greater than the height of the remote control body.

[0011] The four corners of the top surface of the extension shell are fixedly connected with vertically arranged compression springs.

[0012] The technical solution of the present invention has the following positive effects: the outside of the remote control body of the present invention is sheathed with a protective shell with a groove structure, and a protective layer of foam material is provided between the protective shell and the remote control body, which can play a buffering role when the remote control falls; a locking mechanism is provided between the cover plate and the extension shell. When not in use, the cover plate is closed and the locking rod is rotated so that the cover plate is locked, which is not easy to open and the buttons are not easy to touch when not in use; when the cover plate is opened, it can be folded to the bottom of the protective shell and fixed to the bottom of the protective shell by magnets 1 and 2.

[0017] like Figure 1-4 As shown, a crane remote control with good protection effect includes a remote control body 1, a protective shell 2 is sheathed on the outside of the remote control body 1, the protective shell 2 is a groove-shaped structure, a cover plate 3 is connected to one side of the opening at the top of the protective shell 2, a fold 4 is provided at the connection between the cover plate 3 and the protective shell 2, one end of the protective shell 2 is fixedly connected to an extension shell 5, the extension shell 5 is a hollow box-shaped structure, a locking mechanism is provided between the cover plate 3 and the extension shell 5, the locking mechanism includes a sleeve 6, the sleeve 6 is vertically fixedly connected to the inside of the extension shell 5, a connecting shaft 7 is rotatably connected to the sleeve 6 through a bearing, the connecting shaft 7 is vertically arranged, and the top of the connecting shaft 7 is connected to The locking rod 8 and the cover plate 3 are provided with a through hole 9 for the locking rod 8 to pass through; specifically, the protective shell 2 can be made of silicone, which is soft and easy to disassemble; the protective shell 2 is mounted on the outside of the remote control body 1, and the cover plate 3 is covered when not in use to prevent the buttons from being touched. The through hole 9 of the cover plate 3 is passed through the locking rod 8 and the connecting shaft 7, and the locking rod 8 is rotated after passing through so that the locking rod 8 and the through hole 9 are perpendicular to each other, thereby fixing the cover plate 3; when in use, the locking rod 8 is rotated to open the cover plate 3, and then the cover plate 3 is folded so that one side of the cover plate 3 is located at the bottom of the protective shell 2, reducing the unfolded area of ​​the cover plate 3.

[0018] The protective shell 2 is further provided with a second fold 10 , and the distance d between the first fold 4 and the second fold 10 is equal to the height h of the protective shell 2 .

[0019] A magnet 11 is provided on the top surface of the cover 3 and at the position of the through hole 9, and a magnet 2 12 is provided at the bottom of the protective shell 2. Magnet 11 and magnet 2 12 cooperate with each other; when in use, when the cover is folded to the bottom of the protective shell 2, the cover 3 is fixed by magnet 11 and magnet 2 12.

[0020] A protective layer 13 is provided inside the protective shell 2 and is made of foam material. Placing the protective layer 13 inside the protective shell 2 can provide cushioning protection when the remote control falls.

[0021] The protective shell 2 and the extension shell 5 are both made of silicone.

[0022] The extension shell 5 is filled with foam filler 14 .

[0023] The height of the protective shell 2 is greater than the height of the remote control body 1 ; specifically, the top surface of the buttons of the remote control body 1 does not protrude from the protective shell 2 .

[0024] The four corners of the top surface of the extension shell 5 are fixedly connected with vertically arranged compression springs 15; specifically, when the cover plate 3 passes through the locking rod 8, the cover plate 3 will compress the compression spring 15. After the locking rod 8 is rotated and locked, the compression spring 15 restores its deformation, thereby pressing the cover plate 3 against the locking rod 8.
