[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] like Figures 1 to 8 As shown, the present invention provides a forklift with a function of preventing cargo from falling, comprising a main body mechanism 4, and further comprising: A pressing mechanism 1, which is arranged on the front side of the main body mechanism 4; A fork mechanism 2, which is arranged below the pressing mechanism 1; The top pressing mechanism 1 includes a top plate 101, a rack 103, a transmission assembly 105 and a pressure plate 108. The bottom of the top plate 101 is fixedly connected to two racks 103. The side of the rack 103 is driven by a transmission assembly 105 for driving the top plate 101 to rise and fall. A plurality of first cavities 106 are provided inside the top plate 101. The inner wall of the first cavity 106 is fixedly connected to a first spring 107. The bottom of the top plate 101 is slidably connected to a pressure plate 108. The piston rod arranged on the top of the pressure plate 108 is elastically connected to the inner wall of the first cavity 106 through the first spring 107. The fork mechanism 2 comprises a fork plate 201 , and a limiting groove for enabling the rack 103 to slide in a vertical direction is formed on the top of the fork plate 201 .

At the same time, the pressure can be automatically adjusted by the first spring 107 and the gas according to the texture, shape and bearing capacity of the goods to achieve self-adaptive pressure regulation. If the goods are fragile, the first spring 107 and the gas will gradually increase the reaction force during the compression process to prevent the pressure plate from exerting excessive pressure on the goods and causing damage. If the goods are relatively strong, the first spring 107 and the gas can be further compressed to ensure that the goods are firmly fixed.
