When the scaffolder sets up scaffold, in the process of using fastener, nut 6 is usually come off because twist excessive, and (scaffolder is when setting up scaffold, majority are being with gloves, possible feel is bad), after nut 6 came off, bolt 5 also can pass bolt hole and circular hole and come off, and whole like this fastener just loses function of use.Because nut 6 and bolt 5 come off, also need corresponding workman and go to pick up on the ground, to have wasted cost of labor, and when using next time, also needed to go for producer and remove to buy corresponding bolts 5 and nut 6, cost is just than higher, and cost of production also can improve accordingly.And generally, the scaffolder can will not have this class fastener of screw bolt and nut to lose on the ground, the fastener that is easy to lose is fallen into earth or other places that is difficult for finding, and also needs to buy whole fastener like this when using next time, and the cost of production that needs is just higher.
Summary of the invention
The utility model provides a kind of steel tube scaffold clasp, and its nut difficult drop-off can be saved cost of production.
The technical solution of the utility model is: a kind of steel tube scaffold clasp, and it comprises body, buckling piece, screw bolt and nut; Described body is provided with the sleeve that vertical steel pipe is inserted in vertical being used to, and is connected with first end of described buckling piece by rotating shaft in the bottom of described body, and this buckling piece is circular-arc, is provided with the circular hole that is used for inserting bolt in described upper part of body; Second end of described buckling piece is provided with bolt hole, and the head of described bolt passes described circular hole and bolt hole successively, and the end is stuck on the circular hole; Described nut is screwed in the head of described bolt;
Head at described bolt also is milled with button hole, and described button hole is removably connected with the block piece that stops that described nut comes off.
Steel tube scaffold clasp of the present utility model, head at described bolt is milled with button hole, this button hole is removably connected with the block piece that stops that nut comes off, so when using steel tube scaffold clasp of the present utility model, nut is after being screwed to bolt, head at nut is removably connected with block piece, can stop that nut comes off from bolt, prevent that nuts and bolt from losing, saved cost of production, also made things convenient for the scaffolder to set up scaffold, and steel tube scaffold clasp of the present utility model is simple in structure, installs easily.
