Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a 3-piece intermediate shaft locking device configured to be capable of selectively fixing shafts by selectively inserting a lock ball mounted on a middle shaft in one of ball fixing recesses formed in a driveshaft and an inner shaft, so that the structure is simple, yet each shaft moves precisely in a lengthwise direction in a set order, and the length can be adjusted according to a predetermined order. In particular, another purpose of the present invention is to provide a 3-piece intermediate shaft locking device configured to be capable of fixing the middle shaft to the driveshaft or the inner shaft according to the length of the shafts adjusted by the lock ball, and capable of sequentially adjusting the length of the intermediate shaft according to a set order, via only a length adjustment of the intermediate shaft. In addition, a further purpose of the present invention is to provide a 3-piece intermediate shaft locking device that operates such that the inner shaft and the middle shaft are made to move together or the middle shaft is fixed to the driveshaft and the inner shaft is made to move by using the lock ball, so that the addition of structural components is minimized and each shaft can be quickly and precisely adjusted in sequence according to a set order.
