Abstract
Embodiments of the present disclosure provides an anti-loosening device and a plunger pump. The anti-loosening device includes a first bracket, a second bracket and an elastic member. The first bracket includes a first clamping part defining a first accommodating space; a first connecting part extending in a first direction and fixedly connected to the first clamping part; and a limiting part fixedly connected to the first clamping part via the first connecting part, wherein the limiting part protrudes from the first connecting part in a second direction perpendicular to the first direction. The second bracket includes a second clamping part defining a second accommodation space, wherein the second clamping part is opposite to the first clamping part in the first direction; and a second connecting part extending in the first direction and fixedly connected to the second clamping part.
