    Abstract: An electric table stand for simple assembly and adjustment includes a beam structure (10), support bars (20), and upright structures (30). Each of the support bars (20) includes a base (21) and a plurality of arms (211, 212, 213) extended from the base (21), wherein an accommodating space (A) is defined by the base (21) and the arms (211, 212, 213). One arm (213) of each of the support bars (20) supports one end of the beam structure (10), and the beam structure (10) is operatively moved in or out of the accommodating space (A). The upright structures (30) are connected to the support bars (20). Accordingly, it is easy to adjust and position each support bar (20) and each upright structure (30) on the beam structure (10).

    Abstract: An actuator with switchable releasing speed includes an actuation rod, a screw, and a motor. The motor drives the screw rotating so that the actuation rod axially moves relative to the screw. The motor includes a stator, a rotor, a plurality of commutators, and at least three brushes. The at least three brushes have a positive brush, a negative brush, and at least one auxiliary brush. The positive brush is connected to a positive DC voltage. One of the negative brush and the least one auxiliary brush is adjusted to connect to a negative DC voltage so as to change a rotational speed of the rotor, thereby controlling a movement speed of the actuation rod. Accordingly, the releasing speed of the actuator is switchable.

    Abstract: A liftable table foot frame (1) that is easily assembled includes a horizontal frame body (10), a post (20), a side wing (30) and a linking mechanism (40). The horizontal frame body (10) includes a horizontal rod (11). One end of the post (20) pivotally connects to the horizontal rod (11). The side wing (30) includes a plate body (31) and inserting blocks (32) connected to the plate body (31). The inserting blocks (32) separately couple with an end of the horizontal rod (11). The linking mechanism (40) connects the post (20) and the side wing (30). When the post (20) is turned out relative to the horizontal rod (11), the inserting blocks (32) are driven toward the horizontal rod (11) through the linking mechanism (40) to tense and position. Thus, easiness and convenience of assembling can be increased.
