Description

Technical Field

[0002] Craft trolleys are generally used to transport goods, etc., but most of the work trolleys on the market are fixed trolleys that cannot be extended or modified. They are subject to many space constraints and have poor flexibility. In actual use, they often require multiple transportations due to the small transportable space. Some trolleys also occupy too much space, resulting in poor flexibility in specific spaces, making transportation impossible. These are practical problems caused by the poor flexibility of fixed trolleys that cannot be modified, and a new craft trolley is urgently needed to solve them.

This solves the problem that process trolleys have many different forms and sizes due to different body-in-white models, and cannot be universal, resulting in too many process trolleys, high costs, and chaotic management. However, although an adjustable support assembly is provided in this patent, the frame body of the trolley is fixed and cannot be adjusted, and there are still many restrictions in space, and the flexibility is poor in certain specific spaces.

Each positioning mechanism is installed on the second telescopic rod 204, which is convenient for adjusting the distance between the positioning mechanisms on the same second telescopic connecting rod, and then the raising or lowering of the variable flexible process trolley can be realized by lifting and lowering the positioning mechanism, thereby meeting more on-site requirements, and also solving the practical problem of poor flexibility caused by the fixed trolley being unable to change in the prior art. It should be noted that the variable flexibility mentioned in this embodiment refers to the flexibility change of being able to be extended, shortened, widened, narrowed, raised or lowered.

[0028] In this embodiment, two pulleys 3 are symmetrically connected below the two ends of the second telescopic connecting rod 2, and the pulleys 3 are connected to the second telescopic connecting rod 2 through the connecting rod 4.
