Coming out of the receptacle (20) one position of the upper structure (12), there is a second opening (42) with a longitudinal groove of the superstructure (12) to make the towing rod lock ( 35) Movable through the second opening (42) for opening and closing functions. The entrance gate (20), one of the pushbars (40) that is connected to the superstructure (12), will be the second pivot point (52) so that the bar (40) is assembled with the locking rod. The towing rod (35) rotates in a circle to set the towing rod lock bar (35) up and down for the Block entrance to the sockets (20) and for opening the sockets (20) at the second pivot point (52), a second set of springs (62) is used to set the press bar (40) in line. It is characterized by that the pressed beam (40) forms the first (31) arc segment and the second (32) arc segment above, with the first (31) arc segment. Contact with the top of the pivot bar (30) when lifting the bar (40) in a needle direction. The towbar lock bar (35) moves upward for opening the sockets (20), and the top part of the pivot bar (30) supports the bar (40) so that it does not turn back. In a counterclockwise direction automatically The traction device that enters the sockets (20) hits the lower pivot pin (30), the lower pivot pin (30) moves in. In anti-clockwise direction with the first pivot point (51) being the center of the upper pivot point of the pin, the pivot bar (30) moves in a counterclockwise direction and detaches from the first (31) arc part of the lever ( 40) which is the support position of the push bar (40) to the second arc section (32) of the bar (32) above and the towbar lock bar (35) moves downward for closing the access door.
