The first support plate 11 is used for arranging the pin shaft 13 and the limiting part 15 thereon. The second support plate 12 is disposed opposite to the first support plate 11 for the positioning portion 14 to be disposed thereon. The pin shafts 13 and the limiting parts 15 are arranged between the first support plate 11 and the second support plate 12, and the number of the pin shafts 13 corresponds to the number of the brackets 20, so that the brackets 20 can be arranged on the pin shafts and can rotate or/and move along the pin shafts, so that the brackets 20 can be unfolded or folded together. The positioning portion 14 may be provided on the second support plate 12 to correspond to the bracket (20) to a preset position for fixing the bracket 20 at the preset position.

In some embodiments, the first support plate 11 and the second support plate 12 are both substantially square and have substantially the same shape and size. The first support plate 11 and the second support plate 12 are disposed opposite to each other, but are not completely attached to each other, but define a receiving space in which the bracket 20 is installed and can move and/or rotate. The pin 13, a portion of the bracket 20, and the stopper 15 are disposed in the accommodating space, so that the bracket 20 moves or rotates along the pin 13.

In some embodiments, the pin 13 may include a first fixing pin passing through the first support plate 11, a second fixing pin passing through the second support plate 12, and a roller covering the first fixing pin and the second fixing pin. The first fixing pin and the second fixing pin are oppositely arranged and are not connected in a low mode, and the roller is sleeved on the first fixing pin and the second fixing pin between the first supporting plate 11 and the second supporting plate 12.

The bearing part 22 is substantially perpendicular to the support part 21 and moves with the movement of the support part 21. The fixing part 23 is used for controlling the tightness of the bearing part 22, namely when the fixing part 23 is loosened, the antenna can be installed on or taken down from the bearing part 22; after the antenna is mounted on the bearing portion 22, the fixing portion 23 is locked to fix the antenna, so as to prevent the antenna from falling off from the supporting portion 21.

In some embodiments, the supporting portion 21 is in the shape of a long strip plate, and one end of the supporting portion located in the accommodating space is provided with a sliding groove 210, which is used for sliding back and forth along the pin 13 and can rotate around the pin 13; one end of the supporting portion 21 located in the accommodating space is connected to the bearing portion 22. As shown in fig. 1 and 4, the sliding groove 210 is disposed in a long hole shape along the longitudinal direction of the supporting portion 21, two ends of the hole are concave arcs, and the width of the long hole is equivalent to the diameter of the arc. The width of the elongated hole is larger than the outer diameter of the roller of the pin shaft 13 so that the roller can be inserted into the sliding groove 210 and can smoothly slide and rotate.

In some embodiments, the supporting portion 21 further defines a plurality of positioning slots 212 spaced apart from each other along the longitudinal direction of the supporting portion 21, so that the positioning slots 212 are disposed corresponding to the positioning portions 14 without being loosened to position the bracket 20 at the predetermined position. In some embodiments, the supporting portion 21 defines two positioning slots 212 spaced apart from each other, the spacing distance between the two positioning slots 212 is equal to the length of the sliding slot, the positioning slot 212 far away from the sliding slot 210 is used for positioning the bracket 20 when the bracket 20 is folded, and the positioning slot 212 near the sliding slot 210 is used for positioning the bracket 20 when the bracket 20 is unfolded. Specifically, when shelves supporting part 21 rotates to first preset position, spacing portion 15's pine does not take off and corresponds the constant head tank, and the fastening pine does not take off, fixes a position support 20 at first preset position, when support 20 need move to second preset position from first preset position, and not hard up pine does not take off, when support 20 moves to second preset position, and the fastening pine does not take off, fixes a position support 20 at second preset position. Of course, the positioning groove may not be provided, and the tightness of the positioning portion 14 may be adjusted to correspond to the tightness of the supporting portion 21, so that the support may be loosened or fastened, or the corresponding supporting portion 21 may be frosted, so that only the support may be loosened or fastened.
