[0022] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.

[0023] like Figure 1-Figure 4 As shown, the sliding lifting platform for a UAV and a fire truck for a forest fire fighting system provided in this embodiment includes a platform body 1, a locking belt 2 is pressed around the top of the platform body 1 by rivets, a handle 3 is bolted to one side of the outer wall of the platform body 1, a button 4 is movably installed at the center of the handle 3, and a guide sleeve 7 is glued to the bottom of the inner wall of the platform body 1;

[0024] A push rod 6 is slidably connected in the inner wall of the guide sleeve 7, and the push rod 6 penetrates the platform body 1 and is threadedly connected to the button 4. A lifting wedge 8 is threadedly screwed on the other end of the push rod 6. When the lifting wedge 8 moves forward, it can compress the ball head column 11 on one side to slide up, thereby changing the direction of the push force of the button 4.

[0025] One side of the lifting wedge block 8 is slidably abutted against a ball stud 11, and the contact surface between the ball stud 11 and the lifting wedge block 8 is smooth.

[0026] The locking belt 2 is made of nylon, and has Velcro on the back. The two sides of the outer bottom of the platform body 1 are symmetrically slidably connected with slide rails 5.

[0027] A plurality of limit holes 17 are provided in the inner wall at the top end of the slide rail 5 , and the limit rods 10 are slidably connected in the limit holes 17 . The limit rods 10 are symmetrically arranged, and the limit holes 17 need to be manually touched when the limit rods 10 are inserted.

[0028] A lifting rod 9 is fixed to the top of the limit rod 10. The lifting rod 9 is made of hard metal. The two sides of the bottom of the lifting rod 9 are symmetrically hooked to connect the limit springs 12. When the lifting rod 9 is pushed up by the ball head column 11 at the center, it tends to rise as a whole and will not deform, causing the two ends to be pulled and deformed by the limit springs 12, which can ensure that the limit rod 10 is pulled out of the socket at the same time.

[0029] The limit spring 12 is installed in the inner wall of the platform body 1 through the support seat 15, and a ball head column 11 is welded at the center of the bottom of the lifting rod 9.
