The length adjustment structure of the gun stock

Abstract

The invention discloses a gun stock length adjusting structure which comprises a gun stock fixed section and a gun stock telescoping section. The gun stock telescoping section sleeves the gun stock fixed section through an inner hole arranged in the gun stock telescoping section and can axially slide along the gun stock fixed section. The external surface of the gun stock fixed section is cylindrical. The inner hole of the gun stock telescoping section is a cylindrical hole. The gun stock telescoping section and the gun stock fixed section are in clearance fit. The gun stock fixed section is radially provided with several telescoping blocks. Shaft axis of each telescoping block is positioned on a same plane. The gun stock telescoping section is provided with a location hole for allowing any one of the telescoping blocks to be inserted therein. When any one of the telescoping blocks is inserted into the location hole, axial location of the gun stock telescoping section is formed, and heads of the other telescoping blocks are contacted with the wall of the gun stock telescoping section's inner hole. The gun stock length adjusting structure provided by the invention can be used to prevent a gun stock from loosening and raise firing accuracy of firearms.
