Electric table stand, coupling thereof, and electric table with electric table stand

摘要

An electric table stand, a coupling thereof, and an electric table with the electric table stand; the electric table stand includes a holder (10), two support legs (20, 30), and a transmission apparatus (40). The two support legs (20, 30) are detachably connected to two ends of the holder (10) and parallel to each other. Each of the support legs (20, 30) includes a screw rod (21) and a first transmission shaft (22) driving the screw rod (21) to rotate. The transmission apparatus (40) is assembled in the holder (10), and includes a motor (41), a second transmission shaft (42) driven by the motor (41) and at least one coupling (43). The coupling (43) includes a first joint (431) connected to the first transmission shaft (22), a second joint (436) connected to the second transmission shaft (42), and a flexible body (440) flexibly pushing the second joint (436) to be correspondingly connected to the first joint (431).
