The invention relates to a semitrailer traction base. The semitrailer traction base comprises a spilt-type base plate, supports and a disconnecting-connecting mechanism. The split-type base plate is mainly composed of a base plate substrate, a central cover plate and an anti-attrition ring. The central cover plate is connected to the base plate substrate. The anti-attrition ring is connected to the central cover plate. The supports are arranged on the two sides of the spilt-type base plate. The disconnecting-connecting mechanism is mainly composed of a joystick, a lever, a wedge block, a latch hook, a joystick double tension spring, a latch hook tension spring and the like. The end of the joystick is hinged to one end of the lever. The wedge block is hinged to the middle of the lever. The latch hook is hinged to the center of the base plate of the traction base. According to the semitrailer traction base, the base plate of the traction base is designed to be in a spilt type, and a mode that bolts are welded from bottom to top and nuts are screwed from top to bottom is adopted; when the latch hook is replaced, only the central cover plate needs to be detached; a generally adopted tedious mode that the latch hook can not be replaced unless the whole traction base is detached from a tractor at present can be replaced, so that the replacement of parts and components is quick and convenient, and the maintenance efficiency is greatly improved.
