A trough connecting element, which can be disconnected and connected quickly and repeatedly, includes a bow-shaped trough and a handclasp-shaped trough. The cross section of the bow trough is as a bowed person, and it is consisted of an F shape trough and an integrated block strip. The cross section of the handclasp trough is as a handclasp-shaped hand, and it is consisted of a C shape trough and an integrated block strip. After the trough connecting element is fitted, it can't be disconnected in any direction parallel to the cross section. Said trough can prevent sliding.
