The invention discloses a high-precision high-speed ribbon loom with stable operation. The high-precision high-speed ribbon loom comprises a ribbon loom body, fixing plates are fixedly connected to the bottoms of the two sides of the ribbon loom body respectively, a bottom plate is arranged at the bottom of the ribbon loom body, installing holes are formed in the top of the bottom plate, shells are fixedly connected to the four corners of the top of the bottom plate respectively, and springs are arranged at the bottoms of inner cavities of the shells. By using the ribbon loom body, first reinforcing plates, the shells, the installing holes, the bottom plate, fixing tubes, lifting rods, the fixing plates, third reinforcing plates, supporting plates, second threaded rods, connecting plates,positioning rods, knobs, telescopic rods, positioning holes, second threaded holes, the springs, sliding plates, limiting plates, first threaded rods, first threaded holes and threaded blocks in cooperation, the problem is solved that an existing high-precision high-speed ribbon loom is poor in stability during operation, and the high-precision high-speed ribbon loom has the advantage of being stable in operation and is worthy of popularization.
