Detailed Description

The present invention will be described in further detail with reference to examples and specific embodiments.

As shown in fig. 1, truss and base bracing that can take up and expand fast, its structure includes interconnect's truss 2 and base 1, peg graft in the sleeve 3 at base 1 top 2 bottom of truss, 2 outside covers of truss are equipped with cotter frame 18, four limits centers in base 1 bottom are equipped with truckle 5 respectively, install height-adjustable's pad foot 6 on four angles of base 1 respectively, truss 2 four sides middle part is rotated respectively and is connected a telescopic tube mechanism, 1 four sides middle part of base rotates respectively and connects a exhibition arm 4, exhibition arm 4 top surface is close to outer end department and is equipped with the grafting section of thick bamboo that supplies telescopic tube mechanism to peg graft, height-adjustable's pad foot 6 also is equipped with to exhibition arm 4 outer end.

The foot pad 6 is installed on the screw rod, and the top end of the screw rod is connected with the screw cap 7. The height of the foot pad 6 can be adjusted by adjusting the extension length of the screw and fixing the nut.

The telescopic tube mechanism includes that sleeve pipe 8 and one end sliding connection have slotted pipe 9 in sleeve pipe 8 one end, and the middle part in 2 sides of truss is connected in the rotation of the 9 other ends of slotted pipe, and the cooperation is described to the grafting cylindric on the 8 other ends of sleeve pipe and the exhibition arm 4, and through being connected with fastening knob 17 on the lateral surface that sleeve pipe 8 is close to one end, fastening knob 17 medial extremity is located the inslot of slotted pipe 9. The length of the telescopic mechanism can be adjusted, and the relative position of the sleeve 8 and the slotted round pipe 9 can be fixed through the fastening knob 17, namely the length of the telescopic mechanism is fixed.
