The bidirectional set is connected to the fixing set, is movably mounted in the elongated tube and has a connecting panel formed on and protruding from the bidirectional set and extending out of the opening. The extending set is pivotally connected to the bidirectional set and has a guiding track, an extending arm, a locking board and a connecting panel. The extending arm is movably mounted in the guiding track and has a connecting end extending out of the guiding track. The locking board engages the guiding track and is connected to the extending arm to adjust a total length of the extending set.
