On, to be installed on the drive end actively put on case 42 under original state due to actively replying the stretching action of spring 43 in the present invention
Fixture 5 is inclined, and when lifting, side frame 6 first supports its other end by the drive end fixture 5 under heeling condition in the present invention
Bottom continues to lift, then the upper part under the gravity of side frame 6 of drive end fixture 5 is put to close to the direction of driven end pendulum case 2
6 other end top of side frame is moved and clamped, 6 other end of side frame is gripped to realize；When the assembling of side frame 6 finishes and by side
When frame 6 is hung out, 5 top of drive end fixture is swung under the action of actively replying spring 43 to the direction far from driven end pendulum case 2, from
And be detached from and side frame other end top is gripped, continue to lift, side frame 6 can be detached from and actively put case 42, borrow in the present invention
It helps the swing type design of drive end pendulum case 2 to realize the dropping place clamping of 6 other end of side frame using gravity and hang and rises de- folder.This hair
Drive end cushion block 46 can also be installed in bright on active pedestal 41, made with actively putting the abutting of case 42 by 46 pairs of drive end cushion block
Actively put case 42 with limitation and reset oscillating stroke, while can also reduce when actively putting the reset swing of case 42 to actively replying spring 43
Percussion.
It specifically, driven end fixture 3 is identical with 5 structure of drive end fixture in the present invention, and include backboard 51, upper vertical plate
52, lower vertical plate 53, left risers 54 and right risers 55, upper vertical plate 52, lower vertical plate 53 are opposite to be installed on upper and lower the two of 51 side of backboard
End, the opposite left and right both ends for being installed on 51 side of backboard of left risers 54, right risers 55, driven end fixture 3 and drive end fixture 5
It is installed on slave pendulum case 22 by the way that backboard 51 is corresponding respectively and actively puts on case 42, when the lifting of side frame 6 and one end in the present invention
Bottom, which is sat, is set on lower vertical plate 53 driven end fixture 3 afterwards and drive end fixture 5 under 6 gravity of side frame to side close to each other
To swing and be resisted against 6 one end end of side frame on backboard 51,6 one end top of side frame is connected on upper vertical plate 52, to realize
The abrasion to fixture 5 is reduced to gripping for side frame 6, in the present invention, installation that can also be detachable on upper vertical plate 52
Two spaced first wearing plates 521, and in the second wearing plate of installation 511 detachable on backboard 51, then at lower vertical
It is detachable on plate 53 that third wearing plate 531 is installed, in this way when side frame 6 lifts and one end bottom is sat and is set to third and wears away
Driven end fixture 3 and drive end fixture 5 swing to direction close to each other and are resisted against 6 one end end of side frame after on plate 531
On second wearing plate 511,6 one end top of side frame be connected between two the first wearing plates 521, the present invention in by setting abrasion
Plate can be needed with preventing the direct abrasion to fixture by the clamping that the replacement to wearing plate adapts to different model side frame.
The above is only preferred embodiments, not limit the implementation manners and the protection scope of the present invention, should can realize
To be all with equivalent replacement made by description of the invention and diagramatic content and obviously to change obtained side
Case should all be included within the scope of the present invention.
