The invention discloses a universal arm platform, which comprises a pallet and a universal arm, wherein the universal arm is connected with the pallet and comprises a plurality of same universal joint units; each universal joint unit comprises a universal joint head, a universal joint tail and a through hole; the through hole penetrates through the universal joint head and the universal joint tail; the universal joint head is spherical; the universal joint tail is provided with a cavity matched with the universal joint head; and the universal joint head of one universal joint unit and the universal joint tail of another universal joint unit adjacent to the universal joint unit are assembled together. By the universal arm platform, the universal arm can be bent and rotated nearly at any angle in a space; the pallet can be continuously or discontinuously rotated, so that all-dimensional observation and accurate operation are facilitated; a plurality of universal arms can be quickly, easily and conveniently mounted, so that complicated objects can be positioned in various spaces; a fixture can be conveniently and quickly replaced, so that objects with different sizes and shapes are suitable to be fixed, and the fixture and other parts are difficult to loose; and a printed circuit board (PCB) of a wide size can be fixed through a simple structure, and the universal arm platform can be flexibly, easily and conveniently operated. |
