Abstract:
1. A holding apparatus, comprising: a main body having a geometric center; a first clamping member movably and partially disposed in the main body, the first clamping member having a first transmission end and a first clamping end extending out of the main body; a second clamping member movably and partially disposed in the main body, the second clamping member having a second transmission end and a second clamping end extending out of the main body; a third clamping member movably and partially disposed in the main body, the third clamping member having a third transmission end and a third clamping end extending out of the main body; and a pair of transmission assembly disposed in the main body, one of the pair of the transmission assembly connected between the first transmission end of the first clamping member and the second transmission end of the second clamping member, the other of the transmission assembly connected between the first transmission end of the first clamping member and the third transmission end of the third clamping member; wherein each of the pair of transmission assembly includes at least one transmission member and at least one sliding-track, the at least one sliding-track is slantedly formed on the first transmission end of the first clamping member with respect to the first direction, the second and the third transmission end each has the transmission member slidably coupled to the sliding-track, wherein when one of the first, second and third clamping members sides, the pair of transmission assembly are driven so as to drive the remaining of the first, second and third clamping members side; wherein when the distance between the first clamping end and the geometric center is minimum, the distance between the second clamping end and the geometric center is maximum and the distance between the third clamping end and the geometric center is maximum; wherein when the distance between the first clamping end and the geometric center is maximum, the distance between the second clamping end and the geometric center is minimum and the distance between the third clamping end and the geometric center is minimum.
