[summary of the invention]
In order to overcome the deficiency in the background technique, the utility model discloses a kind of used with tractor fastening screw trip bolt, the utility model fixed plate makes screw be fixed on workpiece top, so that screw is difficult for losing, when workpiece is installed, only need workpiece is fastened on the fuselage, hand-held torsion circle is screwed screw, workpiece can be fixed on the fuselage, needn't use special tool can carry out dismounting.
For achieving the above object, the utility model adopts following technological scheme:
A kind of used with tractor fastening screw trip bolt, comprise screw, torsion circle and fixed plate, the screw head two ends of described screw are arranged with draw-in groove, described draw-in groove and torsion circle clamping, the screw head upper side of described screw is provided with groove, be provided with screw thread on the screw rod of described screw, the fixed plate endoporus of described fixed plate is fastened on the periphery of screw rod of threaded upper end.
Described used with tractor fastening screw trip bolt, the screw rod of described screw are thin ends and thick middle ladder rod shaped structure, and thick part is provided with screw thread in the centre of screw rod.
Described used with tractor fastening screw trip bolt, described torsion circle are " U " shape structure, are provided with inside card handle at the two ends of " U " shape structure, and described card handle is connected in the draw-in groove.
Described used with tractor fastening screw trip bolt, the groove that arranges on the described screw head upper side is " one " font or " ten " character form structure.
Described used with tractor fastening screw trip bolt, described fixed plate are cirque structure, and the middle part of fixed plate is provided with the fixed plate endoporus, and described fixed plate endoporus is that upper end open is large, the taper circular hole that lower ending opening is little.
Described used with tractor fastening screw trip bolt, the lower end of described screw rod is set to the taper chamfering.
Owing to adopt aforesaid technological scheme, the utlity model has following beneficial effect:
Used with tractor fastening screw trip bolt described in the utility model, during the dismounting workpiece, only with hand is screwed torsion circle makes screw break away from fuselage, fixed plate makes screw be fixed on workpiece top, so that screw is difficult for losing, when workpiece is installed, only need workpiece is fastened on the fuselage, hand-held torsion circle is screwed screw, workpiece can be fixed on the fuselage, needn't use special tool can carry out dismounting.
