[0009] The slider is symmetrically and staggered up and down at one end of the base, and the other end of the base is fixed to the inner side of the mounting hole of the door panel through a barb at the edge or a quick-release cover with a barb, or fixed to the bottom of the mounting hole of the door panel through a pressure plate. The above is a structural embodiment in which the slider, ratchet buckle, and ratchet shaft are arranged at one end, and the existing pressure plate, barb or quick-release cover is arranged at the other end.

[0010] Through holes for setting the slider are respectively provided on both sides of the chamber of the slider of the base, so that the slider can be easily placed or set through any side of the through hole of the base.

[0011] The bottom of the base is provided with L-shaped limiting ribs symmetrically raised in pairs, and the limiting ribs of the base are raised to fit the inner diameter of the mounting hole of the door panel.

[0012] A handle assembly is arranged in the handle groove at the top of the base, one end of the handle of the handle assembly is connected to the steel bolt assembly through a handle shaft extending out of the bottom of the base, and a torsion spring is arranged at the connection between the handle shaft and the handle.

[0013] A positioning piece is provided at the connection between the handle rotating shaft and the steel bolt assembly.

[0014] The utility model has reasonable structural design, convenient production and loading and unloading, low production cost, good stability, simple adjustment and wide application range; it is suitable for use as a ratchet-type installation lock and similar cabinet door plane locks, as well as a structural improvement of similar products.
