The specific embodiment

Below in conjunction with accompanying drawing embodiments of the invention are further detailed.

Fig. 1 is a front view of the present invention, and worktable panel A-A's analyses and observe among demonstration Fig. 3; Fig. 2 is the left view of Fig. 1; Fig. 3 is the vertical view of Fig. 1.

As shown in the figure, the present invention provides a kind of reductor of ability moment reinforcement, and the reductor of said ability moment reinforcement comprises: the reductor 9 that is connected with motor 11; Turning arm 2.

The present invention is fixed with work top 1 on said reductor 9 shells, protrusion is fixed with central shaft 3 and the endless groove 14 that is positioned at central shaft 3 eccentric parts above the said work top 1, the output axle center of the corresponding reductor 9 in the center of said central shaft 3; The speed reducer output shaft 4 of said reductor 9 connects turning arm 2 one ends, and the eccentric part of turning arm 2 other ends is fixed with bending axis 5, and said bending axis 5 protrusions are arranged in the endless groove 14 and rotate moment reinforcement 13 around central shaft 3.

Between said reductor 9 shells and the work top 1 link 12 is arranged, the bottom of said link 12 is fixed on reductor 9 casings, link 12 top steady job deck plates 1.
