CONSTITUTION: A movable multi-purposes cross linkage(40) comprises a support block(10) and a fixed shaft(20). The supporting block comprises a plurality of through holes(11), backing planes(12) on both sides, and a shaft grove(14) in the lower part. The backing planes comprise a fitting projection(15) and fitting groove(16) to be inserted by being crossed. A separation prevention member(21) is inserted into the fixed shaft, thereby joining the supporting blocks to be rotated. |
