The invention relates to an anti-loosening door handle square strip which comprises a long square strip body, a first tooth row area is arranged on one side of the long square strip body, a middle square strip body and a short square strip body are spliced on one side of the long square strip body, and a second tooth row area is arranged on the side face of the short square strip body. The second tooth-row area with the short square strip is adjustably attached to the first tooth-row area with the long square strip, a fixing hole is further formed in the short square strip, and the axis of the fixing hole is normal to the second tooth-row area; the device further comprises a set screw, and the head of the set screw is plugged into the fixing hole in the short square strip. The square strip has the beneficial effects that 1, the square strip and the handle are fixed by tightening the set screw through the fixing hole in one side surface, and the unthreaded hole is formed in the square strip, so that the phenomenon that the set screw cannot be screwed in due to unsmooth tooth grains when the set screw is screwed in is overcome, the whole square strip and the handle are not loosened due to splayed opening, and the service life of the square strip and the handle is prolonged; and the service life is prolonged.
本发明涉及一种防松动门把手方条，包括一个方条长，所述方条长一侧设有第一排齿区，所述方条长一侧拼合有一段方条中和一段方条短，所述方条短侧面是第二排齿区；所述方条短的第二排齿区可调的贴合在方条长的第一排齿区上，所述方条短上还设有一个固定孔，所述固定孔的轴线法向于第二排齿区；还包括一个紧定螺钉，所述紧定螺钉的头部塞入方条短上的固定孔中。本发明的有益效果在于：1、方条与把手的固定是由一个侧面上的固定孔加紧定螺钉实现的，并且由于方条上的是光孔，从而克服了紧定螺钉在旋入时由于牙纹不顺产生的无法拧入的现象，整个方条与把手不在产生八字开产生的松动，提高了使用寿命。
