Fixing device used for assembling rocker components

The invention discloses a fixing device used for assembling rocker components. The fixing device comprises a base plate and a pressing mechanism. The base plate is provided with a plurality of positioning grooves for accommodating a plurality of rocker components to be assembled, the pressing mechanism is arranged on the base plate and used for pressing the rocker components to be assembled on the positioning grooves. By the arrangement, the rocker components to be assembled can be reliably fixed, swinging leftwards and rightwards can be avoided, and fixing efficiency is high; in addition, the rocker components to be assembled can be fixed in one step, so that operation efficiency is greatly improved; besides, the rocker components to be assembled can be tightly pressed through the fixing device, and lifting of products can be avoided.
