There is an urgent need for a mechanism that can quickly achieve equipment positioning, especially large equipment.

[0003] The main purpose of the utility model is to provide a device rapid positioning mechanism, which can conveniently, quickly and accurately position the device and shorten the positioning time. [Utility Model Content]

The lower frame (101) is slidably connected to the longitudinal "convex" guide rails (103) of the base frame through the "concave" annular grooves of the four rollers (108).

[0006] In one embodiment of the utility model, the driving component includes a first reduction motor (200), which is fixed to the outer side of the lower frame (105) through a mounting plate, and its output shaft is connected to the roller output shaft (202) through a coupling (201). The first reduction motor outputs motion to the roller (202), and the roller moves horizontally along the slide rail, driving the lower frame (105) and the upper frame (107) to move horizontally as a whole.
