[0038] And the fixed mechanism for limiting the movement of the convex ring 7 when the pin shaft rod 8 and the pin hole are inserted.

[0039] The fixed mechanism comprises a permanent magnet ring 9 fixedly installed on one side of the rotating plate 5, and a permanent magnet block 10 fixedly installed on one side of the movable convex ring 7 and magnetically connected with the permanent magnet ring 9.

[0040] The other side of the movable convex ring 7 is fixedly installed with a pulling rod 11, and a plurality of pin holes are uniformly distributed on the rotating plate 5 in a circumferential array.

[0041] The technical scheme provided by the embodiment is as follows: when in use, the electrical box can be placed by supporting through the fixed support plate 2 and the movable support plate 3, and the electrical box after being eliminated or replaced can be conveniently stored; when the distance between the fixed support plate 2 and the movable support plate 3 needs to be adjusted, the movable convex ring 7 is moved on the limiting shaft 4 by moving the pulling rod 11 on both sides, so that the pin shaft rod 8 and the pin hole are separated, and the permanent magnet ring 9 and the permanent magnet block 10 are separated; then the rotating plate 5 is rotated to a certain angle, and the rotating plate 5 is rotated synchronously to drive the connecting rod 6 to rotate, so that the connecting rod 6 drives the two movable support plates 3 to slide synchronously along the surface of the support frame 1, so as to change the interval space between the fixed support plate 2 and the movable support plate 3; after adjustment, the movable convex ring 7 is moved to reset through the pulling rod 11 again, so that the pin shaft rod 8 is inserted into the corresponding pin hole to fix the rotating plate 5, and the permanent magnet ring 9 and the permanent magnet block 10 are magnetically adsorbed to each other, so as to fix the movable convex ring 7, so that the pin shaft rod 8 and the pin hole are not easy to separate; therefore, the interval height between the plurality of support plates is synchronously and quickly adjusted, the situation of adjusting each support plate one by one is avoided, the operation steps of adjusting the interval of the support plates are reduced, and the efficiency and use effect of the placing frame adjustment are effectively improved.

[0042] Further, a plurality of connecting screw holes 12 are arranged on the surface of the support frame 1 at intervals along the axial direction, and a fixed bolt 13 screw-connected with the connecting screw hole 12 is threadedly connected to the fixed support plate 2.

[0049] The technical solution provided in this embodiment is as follows: When it is necessary to move the position of the placement rack, the hand screw 16 is turned to drive the connecting block 17 to move downward, thereby causing the swivel caster 18 to move downward and contact the ground, and lifting the support frame 1 off the ground. At this time, under the action of the swivel caster 18, the support frame 1 can be pushed to move, thereby adjusting the position of the placement rack. This makes it convenient to move the placement rack according to the needs and facilitates personnel operation. After moving to the appropriate position, the hand screw 16 is turned back again to make the swivel caster 18 move upward and separate from the ground.

[0050] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
