Abstract

The invention relates to a central contraction type installation tool for a split nested one-sided bolt fastener. The central contraction type installation tool for the split nested one-sided bolt fastener comprises a bolt operating rod, spacer supporting rods, a base and a plurality of rocker arm mechanisms which are evenly distributed on the base and can be elastically bent towards the center. A through hole is formed in the center of the base, and the bolt operating rod penetrates through the through hole. The spacer supporting rods are connected with the rocker arm mechanisms. The number of split spacers, the number of the spacer supporting rods and the number of the rocker arm mechanisms are the same. Compared with installation tools in the prior art, the installation tool, disclosed by the invention, can achieve rapid and efficient installation of the split nested one-sided bolt fastener, and enables batch work to be conducted on construction and industrial sites conveniently.

Description

technical field [0001] The invention relates to the technical fields of civil engineering and mechanical assembly, in particular to a center-shrinking type split nested single-side bolt fastener installation tool. Background technique [0002] At present, in the field of civil engineering and mechanical installation, there is a large demand for the installation of connection and fastening of structural parts. As far as bolts are commonly used at present, when performing connection and fastening operations on components, workers need to work on both sides of the component at the same time, that is, insert a bolt with a nut on one side, and then use a tool to tighten the nut on the other side . This connection and fastening method has simple structure, convenient operation and good load bearing, but it is only suitable for open cross-section components. In some special occasions, such as connecting and fastening closed cross-section components or components that are inconveni...
