Abstract

PURPOSE: To extend and shorten a rack chain and a holding body by driving a gear by a method wherein the telescopic holding body is provided on a supporting body and a gear provided in the supporting body is made to engage with the teeth form of the rack chain connected with the tip piece of the holding body.
CONSTITUTION: When a driving gear 15 provided in a supporting body 1 is driven clockwise, transmitting gears 13 and 14 and gears 9 and 10 coaxial thereto rotate together clockwise, since transmitting gears 11 and 12, as well as gears 7 and 8 coaxial thereto, are engaged with the transmitting gears 13 and 14. Accordingly, a rack chain 6 held by the gears 7W10 is pushed out forward from the supporting body 1, while the bent parts of the rack chain 6, contacting with the wall surfaces of holding pieces 2W4 of the holding body alternately, are pushed out forward and extend the holding pieces 2W5 of the holding body. When the driving gear 15 is rotated counterclockwise, the holding pieces 2W5 of the holding body are shortened in the same way.
