[0009] Preferably, the limiting portion is columnar and coaxially aligned with the telescopic shaft, the limiting portion is provided with a spiral outer groove, the spring hoop is provided in the outer groove, and the part of the spring hoop provided on the limiting portion is relatively fixed, so that the springs on both sides of the limiting portion have the function of working independently, but only one spring needs to be installed. When making a large-sized acrylic plate, the limiting portion can be provided to reduce the requirements for the preparation of the spring.

[0010] Preferably, a clamping plate is hinged on the first slider, and by sliding the first slider and flipping the clamping plate, the clamping plate can form a locking fit with a limiting groove provided on the first hinge plate, and the limiting groove is located on a protrusion provided on the first hinge plate. In the locking fit state, the position of the telescopic shaft is locked so that the telescopic shaft will not retract when it is inserted into the socket of another acrylic plate.

[0011] Preferably, the first slider is rotatably connected to an L-shaped rod, the L-shaped rod is connected to a telescopic rod, and a cleaning brush is provided at the outer end of the telescopic rod. The cleaning brush on the L-shaped rod can be used to swing and clean the outer surface of the first hinge plate.

[0013] Preferably, the maximum turning angle between the first hinge plate and the second hinge plate is 180°, and the angle is limited to ensure stability.

[0014] Preferably, the locking mechanism includes a screw, and a first fixed block and a second fixed block respectively fixed to the first hinge plate and the second hinge plate, the second fixed block and the second fixed block are fixed by the screw, the bolt passes through the first hinge plate and the second hinge plate, and the closed state is fastened by the screw, and the first hinge plate or the second hinge plate will not be damaged during operation.

[0015] The utility model has the following beneficial effects: the exhibits can be placed in the interlayer area and then closed, and then connected with screws and bolts for hanging display. Since the two ends of the spring are respectively fixed to the first plug block and the second slider, when not closed, it can present a semi-open natural folding state, and when closed, a certain torsional force of the spring must be overcome; two acrylic plates of the present invention can also be taken, both unfolded, and the inner sides thereof are fitted together, connected by screws, and similarly connected with bolts, so that the amount of hanging display can be increased; the axial movement of the telescopic shaft can also be operated, and the position of the telescopic shaft can be stabilized by flipping the clamping piece to the limit groove, so that it can be inserted into the jack of another acrylic plate of the present invention, and the position of the jack is as follows: Figure 2 As shown by the dotted line in the middle, after rotating the socket upward, there is no need to hang the acrylic plate above, and only plugging is required; in addition, the cleaning brush can be used for cleaning by rotating the L-shaped rod, and the telescopic rod or slider can be used for cleaning as needed. It can be spliced ​​and used, and it is convenient to install exhibits, and it has various functions. The change of operation form can realize function conversion and meet more user needs.
