Further improve, the extension rod tip slides and is provided with the sliding block, be connected with the answer spring on the sliding block, the sliding block inwards slides and gets into the montant module, the sliding block outwards slides and is fixed in on the montant module.

Compared with the prior art, the invention has the advantages that: when horizontal pole module and montant module are not spliced, and when all being in minimum module, convenient shipment.

When not assembling, the horizontal pole module is in minimum mode, when needs expand into certain rectangle shape, can rotate first scissors pole and second scissors pole earlier, makes it reach required angle size, wherein because two fixture blocks in the knob subassembly before not assembling are the card in two slots of stepping down on first scissors pole upper surface earlier to the capstan lower extreme concreties with first connecting rod, consequently when rotatory first scissors pole and second scissors pole, the structure that the inside assembly is good can be along with moving together. Then, the four extension rods are simultaneously pulled out to reach the required extension length, after the angle and the length are adjusted, two clamping blocks on the knob assembly are simultaneously pressed to be separated from the abdicating hole, at the moment, the consolidation sliding block downwards slides under the action of the sliding rod until being matched and connected with a consolidation concave hole on the second connecting rod, and then the consolidation sliding block clockwise rotates for a certain angle. Then loosen two fixture blocks, the fixture block slides into two other spacing grooves under the reset spring effect, and consolidation slider does not reset this moment, still is connected with the second connecting rod, and consequently first connecting rod and the unable relative rotation of second connecting rod in this time, and because knob subassembly also is connected with first scissors fork pole, so first scissors fork pole and second scissors fork pole also can't relative rotation. Therefore, the effect of clamping the extension rod and fixing the first scissor rod and the second scissor is achieved by rotating the knob assembly once, so that a plurality of operation steps are omitted, and the purpose of simple assembly is achieved. The reverse operation is sufficient to recover the minimum mode.

When not assembling, the montant module is in minimum mode, when needs expand into certain length, need tensile loop bar can (can only draw the loop bar group of one side also can two draw simultaneously), because the wedge fixture block among the chucking mechanism in the loop bar can slide with corresponding tooth-shaped groove in the joint pole relatively in the loop bar is tensile to in sliding to in the tooth-shaped groove after the real-time chucking of effect under the spring beam. And because the clamping part of the wedge-shaped clamping block is consistent with the shape of the tooth-shaped groove, the loop bars can rotate and be fixed relative to the clamping bar, and the function of the fixing plate is to enable the two loop bars to rotate simultaneously so as to achieve the angle required by the integral assembly. When the loop bar needs to be contracted, the spring bars on the two sides can be directly pressed down, the wedge-shaped fixture blocks are separated through the connecting rod mechanism, and the loop bar slides.

After the transverse rod module and the vertical rod module are adjusted to the required sizes, the sliding block on the extension rod is pressed down to be matched with the hole in the connecting piece of the vertical rod module, the sliding block is loosened, the sliding block is fastened under the action of the return spring, and therefore the four vertical rod modules are assembled. In addition, the two sides of the connecting piece are provided with the grooves, so that the assembled display cabinet units can be mutually combined and overlapped.
