Abstract
The utility model belongs to tools, in particular to a bolt tightening tool, which comprises a left support and a right support, wherein respective one end of the left support and the right support is respectively provided with a through-hole, the inner portions of two through-holes are respectively embedded with a metal sleeve with internal square holes, the external ends of the two through-holes are respectively provided with clamping screws, the other end of the left support is provided with a groove, the two side walls of the groove are respectively provided with an elongated slot, the other end of the right support is provided with a lug boss corresponding to the groove on the left support, the two side walls of the lug boss are provided with two round through-holes, and a straight pin is respectively embedded in each of the two round holes. The bolt tightening tool can sleeve two metal sleeves whose inner shapes are provided with a plurality of square holes on bolt heads of two bolts which are to be tightened, thus the bolts can not rotate when the other ends of the bolts are tightened with nuts, which is convenient for operation. The two supports of the utility model can keep the sliding fit through pins and the elongated slots, the center distance of two metal sleeves can be randomly adjusted, and the internal square metal sleeves can interchange and replace, and have strong universality.
Description
Technical field
The utility model belongs to instrument, relates to a kind of bolt tightening tool.
Background technology
At present, the employed fastenings of engineering machinery field or machine repairing industry has been used outer six sides' (or five sides) bolt and nut in a large number, as you know, tight a bolt or nut in, wherein an end need be fixed, otherwise the nut of the other end or bolt then can't be tightened.Traditional method is to fix the bolt head of an end with another spanner, removes to rotate the nut of the other end again with another spanner, particularly when using fastening bolt in groups, is not easy to operation especially.
Summary of the invention
The purpose of this utility model provides a kind of a kind of bolt tightening tool that an end of bolt is not in groups rotated.Technical solution of the present utility model is, tightening tool is made up of left socle and right support, one end of left socle and right support respectively has a through hole, respectively stud with the metallic sheath of square hole in the band in two through holes, the outer end of two through holes respectively is equipped with trip bolt, the other end of left socle has groove, and the two side of groove respectively has an elongated slot; The other end of right support is provided with and the corresponding boss of left socle upper groove, and the two side of boss has two round tube holes, respectively inserts a straight pin in two circular holes.
The beneficial effects of the utility model, in the utility model has by two interior shapes in many ways the metallic steel cover in hole be enclosed within on the bolt head of two bolts will tightening, bolt just can not rotate in the other end fastening nut of bolt like this, can operate very easily.Two supports of this utility model keep being slidingly matched by pin and elongated slot, and the center distance that can regulate two metallic sheaths arbitrarily is to adapt to the centre-to-centre spacing that will tight a bolt.Interior square metal steel bushing can exchange and replace, and along with the size of the foreign side that will tight a bolt can be selected to change suitable metal steel bushing, versatility is very strong.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
One end of left socle 3 has vertical through hole 9, stud with metallic sheath 2 in the through hole 9, metallic sheath 2 centers have 12 sides' through hole, through hole 9 outer ends on the left socle 3 have thread filament hole 8, trip bolt 1 is installed in the thread filament hole 8, trip bolt 1 compresses metallic sheath 2, and the other end of left socle 3 has an open recess 4, and the two side of groove 4 respectively has an elongated slot 11; One end of right support 5 has vertical through hole 16, stud with metallic sheath 6 in the through hole 16, metallic sheath 6 centers have 12 sides' through hole, through hole 16 outer ends have thread filament hole 17 on the right support 5, trip bolt 7 is installed in the thread filament hole 17, trip bolt 7 compresses metallic sheath 6, the other end of right support 5 has two circular holes 13 and 14, insert round metal pin 8 and 9 in the circular hole 13 and 14 respectively, two circular holes 13 that round metal pin 8 and 9 passes right support 5 with 14 and two place's little elongated slots 11 of left socle 3 sidewalls right support 5 be slidingly connected with left socle 3 be in the same place.
During use, at first change the metal steel bushing that two suitable interior shapes have 12 sides or 10 square holes according to the bolt head size that will tight a bolt, fastening good with trip bolt, regulate the center distance of two metallic sheaths then according to the centre-to-centre spacing of bolt, regulate and two metallic steel covers are enclosed within on the bolt head of two bolts will tightening after suitable, like this when tightening the nut of the other end, owing to two bolt heads all have been fixed, so effectively prevented the rotation of bolt.
