The lock catch structure comprises a first lock catch main body and a second lock catch main body. The first lock catch main body comprises a first base and a first main body rotationally connected to the first base; The second lock catch structure comprises a second base, a second main body rotationally connected to the second base, a handle hinged at the base and a draw-off locking member pivoted with the handle through a pivot shaft; one end of the draw-off locking member is limited in the groove, and the handle rotates around the pivot shaft as the support point, so that the draw-off locking member drives the first lock catch main body to move towards the second lock catch main body until the first inclined surface is pressed against the second inclined main surface.

A latch having a support bracket having a guide slot formed in a bottom surface. A linkage at least partially received within the guide slot and a handle coupled to the linkage transitionable between an open position and a closed position. A pin releasably coupled to the linkage such that when the handle is in the closed position the pin is coupled to the linkage and in the open position the pin is removable from the linkage. As the handle transitions from the open position to the closed position, the linkage moves within the guide slot.
