Another end of said upper connecting box section is pivotally connected to a tray plate of the tray member and a lock part and a pair of retarding wheels provided with the lift member. The inclining member is disposed on the lock part and provides a stem handle. The sliding seat is capable of sliding in the fixing plate to move the upper and lower connecting box sections forward and backward. The upper and lower connecting box sections are capable rotating with respect to the sliding seat to perform upward and downward movements with the return spring.
