Description

TECHNICAL FIELD

[0001] The application relates to the technical field of door lock technology, and particularly relates to a fast-mounting handle. BACKGROUND

[0002] With the progress of social science and technology, armored doors, as upgraded products of security doors, have entered more and more families. The hardware used on the armored doors on the market is endless, and with the diversification of the door handles, a fast-mounting handle with stable performance is needed to meet market demand.

[0003] The door handles on the market are roughly divided into two types in the fixing mode. One type needs to first install a base, then fix a square steel integrated with the handle through a jack screw, and then fix an outermost decorative cover. The principle is to fix the square steel on the lock body through an expansion screw. This fixing mode is not stable, and when there is a gap between the square steel and the lock body, the handle will be loose during use. Once the square steel and the lock body are not firmly fixed, the handle will be pulled out during use or for a long time. The other type needs to first install a base with a square steel, then fix the outer decorative cover on the base through a rotating mode, and finally fix the handle on the square steel through a jack screw. This fixing mode needs to see whether the jack screw can be loosened after long-time use. If the handle is loosened, the handle will also shake or even be pulled out. Therefore, the above problems need to be solved. SUMMARY
