The invention discloses a height-adjustable crowbar with a support. The front end of the crowbar is a crowbar head, and the back end is a pattern handle; a rotating shaft fulcrum is arranged at the middle front end of the crowbar, and is mounted in rotating shaft holes in a support column with a base; and the support column is provided with four rotating shaft holes with different heights. The height-adjustable crowbar with the support can prevent the trouble of searching another support point in weight prizing, can adjust the height of the support point as required to realize quick and convenient weight prizing operation, and achieves the effects of safety, reliability, labor saving and time saving.
