When the distance between the two fixture blocks is required to be reduced, the tooth cap is outwards pulled out to separate the tooth cap from the fixed gear ring, then the tooth cap is rotated to enable the rotating shaft block to drive the two linkage shafts 3313 and further draw close the two fixture blocks 3312, and then the tooth cap is inserted into the fixed tooth cap to be fixed. When the distance between the two clamping blocks 3312 is required to be increased, the tooth cap is pulled out outwards to separate the tooth cap from the fixed gear ring, then the tooth cap is rotated in the opposite direction to enable the rotating shaft block to drive the two linkage shafts 3313, so that the two clamping blocks 3312 are supported, and then the tooth cap is inserted into the fixed tooth cap to be fixed.
