Abstract
The utility model relates to mechanical processing plate forceps general tools, in particular to a vertical tap wrench, comprising an upper movable splint, a lower movable splint, a fixed splint, fastening screws, a handle, fixing screws, an upright pole and tap jacks. The upper movable splint and the lower movable splint are connected by three fixing screws in a triangle arrangement, and the upper movable splint, the lower movable splint and the fixed splint are fixed by fastening screws. The lower surface of the fixed splint and the upper surface of the lower movable splint are provided with a rectangular groove, and the fixed splint and the lower movable splint are fixed to form a square tap jack. Owing to the calibration function of the upright pole, the utility model can improve processing precision and is appropriate for rotating operation with one hand. The co-action of three splints and fastening screws can guarantee the tap with strong stationary property, so the tap is not easy to fall off or loosen in the process of use. The special design of the splints size can make the vertical tap wrench applicable to various work needs, and the utility model can work in various special positions or small space.
Description
Technical field
The utility model relates to machining wrench general utility tool, particularly a kind of vertical screw tap hinge hand.
Background technology
At present commercially available screw tap hinge hand is in long-term use, owing to self intrinsic defective, can not guarantee that workpiece and screw tap are on the same axis, make machining accuracy can not reach requirement, also cause the screw thread of being processed random tooth, crooked, problem such as the pitch diameter of thread is little to occur easily, cause workpiece to scrap.
Summary of the invention
The purpose of this utility model provides a kind of vertical screw tap hinge hand, because the demarcation effect of vertical rod can improve machining accuracy, and be suitable for singlehanded rotating operation, in use screw tap is stressed evenly, is unlikely to cause the screw tap fracture because of the bimanualness unbalance stress.The acting in conjunction of the utility model triple laminate and holding screw can guarantee that screw tap has extremely strong stationarity, in use is not easy to come off or loosening.To the unique design of clamping plate size, make it to be applicable to the several work needs, can carry out operation at multiple specific position or small space.
The utility model is made up of last ambulatory splint (1), following ambulatory splint (2), fixed head (3), holding screw (4), handle (5), fixed screw (6), vertical rod (7), screw tap jack (8) etc., it is characterized in that ambulatory splint and following ambulatory splint are fixed screws (6) connection that triangular shape is arranged by three; Last ambulatory splint, following ambulatory splint and fixed head are fixing by holding screw (4); The upper surface of the lower surface of fixed head and following ambulatory splint has right angle groove, forms foursquare screw tap jack (8) after fixed head and following ambulatory splint are fixed.The holding screw (4) of band nut can replace with the holding screw (9) of band rotary handle
At first holding screw is loosened during work, make screw tap can insert the screw tap jack; Then holding screw is tightened and to be used.
Description of drawings:
Fig. 1 is vertical screw tap hinge hand front view.
Fig. 2 is vertical screw tap hinge hand left view.
Fig. 3 is vertical screw tap hinge hand vertical view.
The holding screw of Fig. 4 band rotary handle.
The specific embodiment:
Shown in Fig. 1,3, the utility model mainly comprises ambulatory splint on 1., 2. descends ambulatory splint, 3. fixed head, 4. holding screw, 5. handle, 6. fixed screw, 7. vertical rod, 8. screw tap jack, the 9. holding screw of band rotary handle.It is characterized in that ambulatory splint and following ambulatory splint are fixed screw (6) connection that triangular shape is arranged by three; Last ambulatory splint, following ambulatory splint and fixed head are fixing by holding screw (4); The upper surface of the lower surface of fixed head and following ambulatory splint has right angle groove, forms foursquare screw tap jack (8) after fixed head and following ambulatory splint are fixed.
The holding screw (4) of band nut can replace with the holding screw (9) of band rotary handle.
Claims (2)
1. a vertical screw tap cuts with scissors hand, form by last ambulatory splint (1), following ambulatory splint (2), strap (3), holding screw (4), handle (5), fixed screw (6), vertical rod (7), screw tap jack (8) etc., it is characterized in that ambulatory splint and following ambulatory splint are fixed screws (6) connection that triangular shape is arranged by three; Last ambulatory splint, following ambulatory splint and strap are fixing by holding screw (4); The upper surface of the lower surface of strap and following ambulatory splint has right angle groove, forms foursquare screw tap jack (8) after strap and following ambulatory splint are fixed.
2. vertical screw tap hinge hand according to claim 1, it is characterized in that: the holding screw (4) of band nut can replace with the holding screw (9) of band rotary handle.
