[0019] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0020] Example

[0021] See also Figures 1 to 3As shown, it should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the utility model, so they have no substantial technical significance. Any modification of the structure, change of the proportional relationship or adjustment of the size, without affecting the effects and purposes that can be achieved by the utility model, should still fall within the scope of the technical content disclosed by the utility model. At the same time, if there are references to terms such as "upper", "lower", "left", "right", "middle" and "one" in this specification, they are only for the convenience of description, and are not used to limit the scope of the implementation of the utility model. The change or adjustment of their relative relationship, without substantially changing the technical content, should also be regarded as the scope of the implementation of the utility model.

[0022] The pin shaft placement rack suitable for aerial work vehicles of various specifications in this embodiment includes a frame 1, a crossbeam 2, a column 3, a base 4, a slide 5, a screw assembly 6 and a clamping assembly 7. The crossbeam 2 is arranged in the middle of the frame 1, and a column 3 is arranged at each of the four corners of the frame 1. The column 3 is fixed to the base 4, the slide 5 is arranged on the crossbeam 2, the screw assembly 6 is arranged in the slide 5, and the clamping assembly 7 is controlled by the screw assembly 6.

[0023] The screw assembly 6 in this embodiment includes a screw body 61, a handwheel 63 and a bolt 64. The screw body 61 is arranged in the slide groove 5, the handwheel 63 is fixed to one end of the screw body 61, the bolt 64 is installed on the handwheel 63, and the bolt 64 is in contact with the frame 1. The clamping assembly 7 includes a sliding sleeve 71 and a clamping block 72. The number of the sliding sleeves 71 is two, and the two sliding sleeves 71 are both mounted on the outside of the screw body 61, and the two sliding sleeves 71 are both located in the slide groove 5. A clamping block 72 is respectively arranged on the two sliding sleeves 71, and the two sliding sleeves 71 are connected to the screw body 61 through positive and negative threads respectively.
