At the same time, they cannot play a cushioning role when the object to be jacked is vibrating or fragile. The existing strip lifting airbags such as the application number CN200820171911.0 are composed of an airbag body, an airbag head and an airbag mouth. The cross-sections of the airbag body and the airbag head are flat, and the height H of the airbag is between 10 and 150 mm, which can be conveniently placed under the component to be lifted. The existing strip lifting airbags have the following problems: 1. They are not easy to install on frames and equipment for use; 2. The object to be jacked directly contacts the airbag, which is easy to scratch or break the airbag, causing damage to the airbag, and the entire airbag cannot be used after damage; 3. The jacking surface cannot ensure uniform jacking force at each position, and is greatly affected by the pressure and shape of the object to be jacked at each position. Utility Model Content

The inverted U-shaped top plate 6 can completely wrap the inflatable belt 2 to prevent the inflatable bag from scratching or breaking it, and at the same time distribute the gravity of the object 11 to be lifted evenly to the horizontal plate 601, and evenly distribute it to the inflatable belt 2 on the lower side, so that the overall lifting force is more uniform.

[0023] like Figure 3 The sliding connection structure between the vertical plate 602 and the support plate 1 is specifically as follows: a long hole 6021 is opened on the vertical plate 602, and the long hole 6021 is arranged longitudinally; it also includes a limit pin 9, the rod body of the limit pin 9 passes through the long holes 6021 of the two vertical plates 602 and the support plate 1, and a cotter pin is inserted into the socket of the limit pin 9; when the inflatable bag is inflated or deflated, the inverted U-shaped top plate 6 moves up and down through the limit pin 9 and the long hole 6021.
