As a kind of preferred version, be provided with in the described arm groove for the first position structure to upset sliding motion structure location.The first position structure be arranged so that the second transposition arm can slide arbitrarily and location at an arbitrary position in the arm groove so that upturned position is adjustable.
As further preferred version, described the first position structure is flange or rib.
As a kind of preferred version, be equipped with in the described sliding-groove stretching out the second position structure of sliding motion structure location.The flexible of the first transposition arm and the second transposition arm that be arranged so that of the second position structure can arrange arbitrarily, so that telescopic location is adjustable.
As further preferred version, described the second position structure is flange or rib.
As a kind of preferred version, described upset sliding motion structure is slide blocks.
As a kind of preferred version, the described sliding motion structure that stretches out is slide blocks.
Compared with prior art, the beneficial effect of technical solution of the present invention is:
(1) the present invention utilizes simple interleaved structure, can realize simultaneously stretching out and flip-flop movement, greatly facilitates the maintenance of screen.
(2) the present invention with screen before enclosed structure stretch out mechanism and switching mechanism unites two into one, greatly simplified maintenance mechanism before the screen, simple in structure, with low cost.
(3) the present invention arranges respectively the second position structure and the first position structure in sliding-groove and arm groove, so that telescopic location and upturned position are all adjustable arbitrarily, flexibility is large, makes things convenient for the maintenance of screen.

Embodiment
Below in conjunction with drawings and Examples technological scheme of the present invention is described further.
As shown in Figure 1, be structural representation of the present invention.Maintenance mechanism before a kind of screen, comprise the first supporting frame 1, the second supporting frame 2, the first transposition arm 3 and the second transposition arm 4, radially be provided with arm groove 31, the first transposition arms 3 and the second transposition arm 4 middle parts is rotatably connected by upset sliding motion structure 5 intersections that are installed on the arm groove 31 at the middle part of the first transposition arm 3; The first supporting frame 1 is provided with sliding-groove with the second supporting frame 2 relative ends, and an end of the first transposition arm 3 and the second transposition arm 4 is installed on the sliding-groove by stretching out sliding motion structure 6 respectively; For convenience of description, the sliding-groove of being located on the first supporting frame 1 one ends is called the first sliding-groove 7, the sliding-groove of being located on the second supporting frame 2 one ends is called the second sliding-groove 8, the first transposition arm 3 one ends that intersect after being rotatably connected with the second transposition arm 4 are installed in the first sliding-groove 7 by stretching out sliding motion structure 6, and the second transposition arm 4 similarly is installed in the second sliding-groove 8 by stretching out sliding motion structure 6; The other end of the first transposition arm 3 and the second transposition arm 4 is installed on the other end of the second supporting frame 2 and the first supporting frame 1 by rotary connector 9 respectively.
Wherein overturn sliding motion structure 5 and stretch out sliding motion structure 6 and all can adopt slide blocks to realize, but be not limited to slide blocks.
As shown in Figure 1, the length of sliding-groove of the first transposition arm 3 is installed less than the length of the sliding-groove that the second transposition arm 4 is installed, namely the length of the first sliding-groove 7 is less than the length of the second sliding-groove 8.The second sliding-groove 8 except cooperate sliding up and down of the second transposition arm 4 realize flexible, it also needs to cooperate the second transposition arm 4 to slide along arm groove 31 to realize upset, therefore, the length of the second sliding-groove 8 is larger than the length of the first sliding-groove 7.
In a specific embodiment, be provided with the first position structure in the arm groove 31, be provided with the second position structure in the sliding-groove, the first position structure and the second position structure can adopt flange or rib to realize, the sliding motion structure 5 that is respectively applied to overturn is located arbitrarily after sliding motion structure 6 slides arbitrarily in groove with stretching out, and regulates dilatability and the upset degree of whole mechanism.
During work, can the first supporting frame 1 is fixing, sliding motion structure 6 is stretched out in utilization and the first transposition arm 3, the second transposition arm 4 form one and stretch out mechanism, utilize upset sliding motion structure 5 and the first transposition arm 3 to form a switching mechanism, wherein the second transposition arm 4 and the first supporting frame 1, the second supporting frame 2 form revolute pair, and the first transposition arm 3 and the first supporting frame 1, the second supporting frame 2 form revolute pair and sliding pair.When stretching out sliding motion structure 6 and move up, the first transposition arm 3 and the second transposition arm 4 launch mutually, form to stretch out action, as shown in Figure 2; When being stretched over the end, the first transposition arm 3 and the second transposition arm 4 will stretch out the sliding motion structure locking by the second position structure, the sliding motion structure 5 that will overturn again slides along the arm groove 31 in the first transposition arm 3, the second transposition arm 4 forms the action of upwards lifting, with the second upwards upset of supporting frame 2, realize the upwards upset of whole mechanism, as shown in Figure 3.
