Abstract
The utility model relates to a sleeve wrench for the arrangement and disassembly of head stud, comprising a sleeve and a sleeve-shaped holding frame, wherein a handle via hole is arranged at the upper end of the sleeve, and the sleeve-shaped holding frame is assembled in the sleeve by a clasp; three trapezoid section grooves with the open mouth outward are distributed evenly and open-provided on the holding frame; a plurality of rolling needles are respectively assembled in each groove; a plurality of arc grooves are respectively arranged on the inner wall of the sleeve corresponding to each rolling needle. The gap between the inner diameter of the rolling needle can be changed by the slide way curve of the sleeve inner wall utilizing three rolling needles, and the head stud can be locked or loosed, which realizes the aim of arranging and disassembling the head stud. The utility model has the advantages of simple and convenient operation for the arrangement and disassembly of head stud, greatly reduced labor intensity and increased productivity.
Description
Technical field
The utility model relates to hand tools, is specifically related to a kind of studding installation, pulling off sleeves spanner.
Background technology
Many equipment on bodies such as diesel engine, gas turbine, booster, large-size machine, are provided with the bolt studding of all size.The installation and removal of many studdings, owing to there is not suitable specific purpose tool, operation is trouble very, it uses two nuts to be tightened in mutually on the same studding mostly, utilizes common spanner to rotate one of them nut, carries out the installation and removal of studding.Owing to studding set on the body is numerous, with the installation and removal of this kind method, inefficiency, labour intensity is big.
Summary of the invention
The purpose of this utility model is at the problems referred to above, and a kind of simple, convenient studding, pulling off sleeves spanner of installation and removal that makes studding is provided.
The technical scheme that realizes above-mentioned purpose is: a kind of studding is installed, the pulling off sleeves spanner, it has a upper end sleeve of handle connecting hole and the cover shape bracing frame in snap ring is assemblied in sleeve is set, uniformly on bracing frame offer three uncovered outside trapezoid cross section grooves, in each groove, be respectively fitted with needle roller, on sleeve lining, be respectively arranged with arc groove corresponding to each needle roller.
The utility model utilizes three needle rollers, change gap between needle roller internal diameter and the studding by being arranged at slideway curve on the sleeve lining, pin or unclamp studding, reach the purpose of installation, dismounting studding, the installation of its studding, disassembling section are simply, conveniently, can reduce labor intensity greatly, increase work efficiency.
