Furthermore, the device also comprises a driving piece;
the driving part is connected with the driving part of the driving rod;
the driving piece provides external force for the driving rod so that the driving rod rotates on the lifting frame.
Furthermore, two sides of the lifting frame are respectively provided with an extension limiting nail;
when the extension transmission rod rotates to drive the extension mechanism to be fully opened, the extension limiting nail limits the extension transmission rod to continue rotating.
The utility model has the advantages that:
the utility model provides a double bracing drive frame and electronic sofa support, it is two point supports in present both sides to change the actuating lever into by traditional middle single-point support to shortened both sides fulcrum and this side extension mechanism's distance, in the time of messenger's sofa support unilateral atress, the effort can directly transmit on the fulcrum of this side, guarantees both sides extension device also can be better under the circumstances that receives eccentric force and guarantees the synchronism.
And the extension limiting nail is arranged on the lifting frame, and when the extension transmission rod rotates to drive the extension mechanism to be fully opened, the extension limiting nail limits the extension transmission rod to continue rotating so as to ensure the safety of the sofa support.

Detailed Description
The invention will now be further described with reference to the accompanying drawings. The drawings are simplified schematic diagrams only illustrating the basic structure of the present invention in a schematic manner, and thus show only the components related to the present invention.
Example one
As shown in fig. 2, a double-support driving frame 2 includes a driving rod 21; support pieces 22 are fixedly arranged at two ends of the driving rod 21 respectively, and rotary mounting shafts are arranged on the two support pieces 22 and are suitable for rotatably mounting the driving rod 21; the driving rod 21 has a driving portion 24 in the middle thereof, which is adapted to receive an external force and rotate with the rotation mounting shafts on both sides as a fulcrum.
Specifically, the upper end of each supporting piece 22 is rotatably connected to one end of an extension transmission rod 23, and the other end of the extension transmission rod 23 is connected to the extension mechanism 5. When the stretching mechanism 5 is stressed, the stress can be directly transmitted to the lifting frame 3 through the supporting sheet 22, so that the driving frame can better support the stretching mechanism 5.
The drive frame of this embodiment is supported by traditional middle single-point and is changed present both sides two-point to support to shortened both sides lateral point and this side and extended 5's distance, in the time of making sofa support unilateral atress, the effort can directly transmit on the fulcrum of this side, guarantees that both sides extend the device and also can be better assurance synchronism under the condition that receives eccentric force.
Example two
As shown in fig. 4 to 7, an electric sofa support is provided, which includes a lifting frame 3 and two extending mechanisms 5, wherein the two extending mechanisms 5 are respectively installed at two sides of the lifting frame 3; the double-support driving frame 2 is arranged on the lifting frame 3, the double-support driving frame 2 is rotatably connected with the lifting frame 3 through rotating installation shafts at two ends, and the double-support driving frame 2 is in transmission connection with the extension mechanisms 5 at two sides through two extension transmission rods 23 respectively.
In this embodiment, how the extension mechanism 5 is connected to the lifting frame 3 and the specific structure of the extension mechanism 5 are the same as the extension mechanism 5 on the conventional sofa support, and will not be described herein again.
In particular, the device also comprises a driving piece 4; the driving part 4 is connected with the driving part 24 of the driving rod 21; the driving member 4 provides an external force to the driving rod 21 to rotate the driving rod 21 on the lifting frame 3.
