The invention relates to a bamboo splitter comprising a stand, a panel is arranged on the stand and sequentially provided with a height limiting device, a feeding device, a pressure assisting device, a splitting device and a restraint device, wherein the splitting device is arranged on a transmission box and comprises an upper saw group device and a lower saw group device; the upper saw group device and the lower saw group device both comprise saw group shafts; each saw group shaft is sequentially provided with a positioning baffle plate, a saw blade and a spacer; and the tail ends of the sawgroup shafts are compacted and positioned by double round nuts. The invention has the advantages of being capable of splitting a higher bamboo board (with the height of more than 55 mm), preventing the bamboo board from being clamped in the splitting device through the height limiting device and reducing the vibration of the bamboo board in the splitting process through the pressure assisting device, thereby ensuring the pressure assisting accuracy of the bamboo board; and in addition, the invention restrains the tail end of the bamboo board through the restraint device and prevents the vertical plane of the bamboo board from being dislocated after splitting, thereby ensuring the output rate of bamboo sheets.
