The invention provides a modular spliced slide. The modular spliced slide is formed in a manner that a plurality of modular sub slides are spliced in sequence, each sub slide comprises left and rightarmrest baffle plates and a slide plate, an antiskid device is arranged on the bottom surface of the slide plate, a connecting device and an angle adjusting limiting device are arranged at the front and rear ends of the slide plate, the connecting devices are used for the splicing the sub slides, and the angle adjusting limiting device is used for adjusting the splicing angles of the sub slides. According to the modular spliced slide, the occupancy cost of land is saved due to construction according to the local conditions, and the free combining and splicing are flexible and convenient.
