Synchronous displacement free clutch gear set

The synchronous displacement free clutch gear set comprises the driving gear and the driven gear, a pair of protruding blocks are symmetrically additionally arranged on the two sides of the driving gear, the driving gear is clamped in the middle to form a trapezoid groove for the driven gear to be inserted and meshed, and the beneficial effects that synchronous axial displacement and free clutch synchronous operation can be achieved are achieved. Innovation, creativity and practicability are embodied. 本实用新型一种同步位移自由离合齿轮组，包括主动齿轮和从动齿轮，在主动齿轮的两侧对称增设一对凸块，将主动齿轮卡在中间形成梯形凹槽，供从动齿轮插入啮合，达到既可以同步轴向位移又可以自由离合同步运转的有益效果，体现创新性、创造性和实用性。
