Specific embodiment

Specific embodiment 1: illustrating present embodiment, this reality in conjunction with Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 9 and Figure 14 Applying mode, it includes lower fulcrum bar 1, telescopic rod 2, music score blade assemblies 3 and four supporting legs 4；

The top of lower fulcrum bar 1 is divided into hollow sleeve, and the bottom of lower fulcrum bar 1 sets that there are four respectively match with four supporting legs 4 Slot 1-1, four supporting legs 4 are hinged with the bottom of lower fulcrum bar 1 respectively and can only be flipped up the slot for fastening to and respectively matching In 1-1, the position that lower fulcrum bar 1 closes on supporting leg 4 is equipped with screw thread 1-2, and screw thread 1-2, which is equipped with, to be bonded tightly with four expansion of supporting leg 4 Solid nut 5, telescopic rod 2 is arranged in the sleeve of lower fulcrum bar 1, and the end of telescopic rod 2 and music score blade assemblies 3 are hinged.

Specific embodiment 2: illustrating present embodiment, this implementation in conjunction with Fig. 4, Fig. 5, Fig. 6, Figure 12, Figure 13 and Figure 15 The position that lower fulcrum bar 1 described in mode closes on top is equipped with the screw thread I1-3 of multiple notches, and the top of the lower fulcrum bar 1 is equipped with chamfering 1-4, screw thread I1-3 are equipped with the nut I6 cooperated with chamfering 1-4 and screw thread I1-3.

Present embodiment passes through to be cooperated using the screw thread I1-3 and nut I6 of multiple notches, and setting chamfering 1-4 passes through nut The rotation of I6 makes multiple screw thread I1-3 with notch generate micro-strain, and so that the diameter of 1 top ports of lower fulcrum bar is become smaller will be flexible Bar 2 blocks, in order to fixed telescopic rod 2.

Other compositions and connection relationship are same as the specific embodiment one.

Specific embodiment 3: illustrate present embodiment in conjunction with Fig. 1, Fig. 3, Fig. 7, Fig. 8, Fig. 9, Figure 10 and Figure 11, this Embodiment music score blade assemblies 3 include connecting plate 3-1, two fixed link 3-2 and multiple supporting plate 3-3；

It is hinged between each supporting plate 3-3 and each supporting plate 3-3, each fixed link 3-2 is equipped with through slot 3-2-1, often A fixed link 3-2 is equipped with multiple threaded holes communicated with through slot 3-2-1, is equipped with holding screw, each support in each threaded hole The both ends of plate 3-3 are separately positioned in the through slot 3-2-1 of each fixed link 3-2, connecting plate 3-1 setting it is described one of those On supporting plate 3-3.

It is hinged between each supporting plate 3-3 and each supporting plate 3-3 and can be unfolded and roll up together；

Present embodiment be in order to realize the quick detachable and portable of music score blade assemblies 3, first by two fixed link 3-2 from It is disassembled on the supporting plate 3-3 being hinged, then connecting plate 3-1 is separated with telescopic rod 2, by multiple supporting plate 3- being hinged Volume 3 on lower fulcrum bar 1, and are reinstated rope with two fixed link 3-2 mono- and are tied up on lower fulcrum bar 1, then telescopic rod 2 is shunk, finally Four supporting legs 4 collapse.

Other compositions and connection relationship are identical with embodiment two.

Specific embodiment 4: illustrating present embodiment in conjunction with Fig. 7 and Fig. 8, on connecting plate 3-1 described in present embodiment It is provided with single-pass notch 3-1-1, being provided in single-pass notch 3-1-1 can be along the hinged of single-pass notch 3-1-1 one direction slide-in Part 7, articulation piece 7 and the top of telescopic rod 2 are hinged.
