The outer rod is inserted within the sleeve while the inner rod is inserted within the outer rod. The sleeve comprises a connecting wall bossing out from one side of the sleeve and holes on the same side exposing from the connecting wall. The cram handle has a cram at one end pivotally connected to the connecting wall by a pin. The block is located between the cram of the cram handle and the holes of the sleeve. Springs are located between the block and the outer rod. The block is urged by the springs towards the cam of the cam handle.
