Linkage mechanical arm structure

The utility model discloses a linkage mechanical arm structure, it includes motor combined mechanism, fixed master substrate, two are removed master substrate, two arm mainboards and belt driving mechanism, motor combined mechanism is fixed in on the intermediate position at fixed master substrate's the back, two are removed master substrate symmetry swing joint on fixed master substrate's both ends, the arm mainboard is installed perpendicularly on the removal master substrate's who corresponds front, belt driving mechanism sets up in fixed master substrate's front, belt driving mechanism andtwo removal master substrate are connected, master substrate outside or internal motion of while on fixed master substrate was moved in two drives after motor combined mechanism output power acted onbelt driving mechanism, the advantage is that motor combined mechanism is located between two arm mainboards, and consequently usable belt driving mechanism realizes the linkage of two arm mainboards, has reduced the power co
