Bamboo tube V-shaped supporting device of numerical-control bamboo splitting machine

The invention relates to a bamboo tube V-shaped supporting device of a numerical-control bamboo splitting machine. The bamboo tube V-shaped supporting device consists of two V-shaped supports, which are respectively installed on the front end of a stander and a position adjacent to the middle part of the stander, wherein each V-shaped support is formed by combining a left supporting part and a right supporting part; when a bamboo is split, an oscillating rod in a four-rod mechanism is pushed by plane cams at the left side and the right side of a plate pushing assembly to swing, a rack is driven to move forwards, the rack drives a left gear and a right gear to respectively rotate for 90 degrees along the counterclockwise direction and the clockwise direction, the left supporting part and the right supporting part, which are fixedly connected to a gear and connection seat assembly I and a gear and connection seat assembly II, also rotate for 90 degrees, and a passage which is used for the plate pushing assembly to move forwards is formed; when the plate pushing assembly is returned, the plane cams push the oscillating rod to swing in an opposite direction, the rack is driven to move backwards, the rack drives the left gear and the right gear to rotate for 90 degrees respectively along the clockwise direction and the counterclockwise direction, and the left supporting part and the right supporting part, which are fixedly connected to the gear and connection seat assembly I and the gear and connection seat assembly II, also rotate for 90 degrees to form a V-shaped support.
