Caused sound, reduce influence of the noise to experimental result.
Operating process：When needing to change poly (methyl methacrylate) plate 2, operator rotates block away from the direction of fixed plate 3
9, then rotate clockwise 9 nine ten degree of moving block so that the limited block 8 in cavity 6 no longer contradicts poly (methyl methacrylate) plate 2, Ran Houxiang
The cavity wall conflict for rotating block 9 close to the direction of fixed plate 3 and causing limited block 8 and cavity 6, poly (methyl methacrylate) plate 2 loses
The position-limiting action of limited block 8, now poly (methyl methacrylate) plate 2 is moved up to being separated with fixed plate 3 away from the direction of baffle plate 5,
The sliding block 41 of new poly (methyl methacrylate) plate 2 is directed at dovetail groove 4 again and moved towards baffle plate 5 so that one end of poly (methyl methacrylate) plate 2 with
Baffle plate 5 contradicts, and now the direction away from fixed plate 3 rotates block 9 and rotates counterclockwise 90 degree, then towards close
The direction of fixed plate 3 rotate block 9 cause limited block 8 compression spring 10 extruding force effect under with new poly (methyl methacrylate) plate
2 contradict, so as to realize positioning to new poly (methyl methacrylate) plate 2.
Embodiment 2：It is with the difference of embodiment 1, such as Fig. 7, in order that projection 6 with the inwall of cavity 6 when contradicting
It is not easy to rotate, the side that projection 6 contradicts with the cavity wall of cavity 6 is provided with rubber blanket 16, so as to increase limited block 8 and the cavity wall of cavity 6
Between friction factor, the possibility that projection 6 rotates when being contradicted with the inwall of cavity 6 is reduced, so as to effectively having limited
Slip of the machine glass plate 2 in dovetail groove 4.
The present embodiment is only that it is not to limitation of the present utility model, this area skill to explanation of the present utility model
Art personnel can make the modification of no creative contribution to the present embodiment as needed after this specification is read, but as long as
All protected in right of the present utility model by Patent Law.
