Embodiment
Understand technical solutions of the utility model for ease of those skilled in the art, now in conjunction with Figure of description, technical solutions of the utility model are described further.
As Fig. 1, shown in Fig. 2 and Fig. 3, a kind of scalable branch shear, comprise telescoping handle, described telescoping handle comprises with externally threaded telescoping inner 5 and the female outer telescopic tube 3 of band, described telescoping inner 5 and outer telescopic tube 3 engage each other connection by external screw thread and internal thread, described telescoping inner 5 is connected with stationary knife 7 away from outer telescopic tube 3 end, described outer telescopic tube 3 is connected with away from telescoping inner 5 end determines operating grip 13, described telescoping inner 5 and outer telescopic tube 3 inside are provided with external screw thread and are connected draw-in bar 9 and outside link 10 with engaging each other of internal thread, described draw-in bar 9 is connected with moving knife 6 away from outside link 10 end, described outside link 10 is connected with dynamic operating grip 12 away from draw-in bar 9 end.
Described draw-in bar 9 and outside link 10 lateral surface are provided with axial rectangular channel, described dynamic operating grip 12 is connected with outside link 10 by pulling-on piece 1, moving knife 6 is connected with draw-in bar 9 by pulling-on piece 28, described pulling-on piece 1 and pulling-on piece 28 are provided with the projection adapted with rectangular channel, described projection is stuck in rectangular channel, and described dynamic operating grip 12 is with between pulling-on piece 1, be all connected by bearing pin 2 between moving knife 6 with pulling-on piece 28.
Described telescoping inner 5 outer cover is connected to locking nut 4, and described locking nut 4 is arranged at telescoping inner 5 and outer telescopic tube 3 junction.
Describedly determine to be provided with back-moving spring 1 between operating grip 13 and dynamic operating grip 12, describedly determine to be connected by bearing pin 2 between operating grip 13 and dynamic operating grip 12.
Branch only need be made when the utility model makes the branch shear of technical scheme use to be within the scope of the subtended angle of moving knife 6 and stationary knife 7, manually to mediate dynamic operating grip 12 and determine operating grip 13 and just branch can be cut.When needing the length regulating scissors, as long as the relative position rotating telescoping inner 5 and outer telescopic tube 3 just can regulate the telescoping handle length of branch shear, because outside link 10 and outer telescopic tube pipe 3 link, draw-in bar 9 and telescoping inner 5 link, and therefore need not regulate the length of outer tie rod again and just can directly use.
