Description
Technical field
The present invention mainly discloses a kind of instrument with pivotable location, and especially a kind of working head and lever can be adjusted the instrument of angle relatively.
Background technology
Figure 23 discloses a kind of known angle modulation sled handle, comprise pry head and handle, handle can be adjusted angle with respect to pry head, the side of pry head one end is provided with several locating slots at the position of neighboring edge, positioning pressuring plate of a side pivot joint of handle, positioning pressuring plate snaps in pry head locating slot, makes pry head and handle reach the object of adjusting angle.
The handle of prior art forms two walls because of locating slot, on wall, must be provided with perforation, make latch can pass the perforation pivot joint positioning pressuring plate of wall, like this, the volume of the necessary swelled handle head of design of locating slot, make handle there is the shortcoming that volume is large and heavy, and then increased the cost of material.Even and strengthened the volume of handle head, still there is the defect of easily bursting apart in the wall that is provided with perforation.And handle needs pivot joint to be combined with positioning pressuring plate, more increased the human cost of assembling.Secondly, the locating slot of pry head is located at the side of pry head, and its locating slot has certain width, and positioning pressuring plate is stuck in locating slot, and it only can provide the location compared with wide-angle, and low-angle location cannot be provided.
In realizing process of the present invention, inventor finds that prior art at least exists following problem: the sled handle of this hue angle, the position of its pry head and handle pivot joint must form larger area, has the problem that material cost is high and weight is heavier, and needs pivot joint combination.
Summary of the invention
Embodiment of the present invention technical problem to be solved is to provide a kind of instrument with pivotable location, gets rid of or at least reduces the problem that prior art runs into.
The technical scheme that the present invention takes is to achieve these goals:
The instrument with pivotable location, comprising:
A lever, described lever comprises a pivot end and a holding end, described pivot end outward flange is provided with several positioning tooths; First working head, described the first working head comprises Yu Yige working end, Yi Ge hub switch side, the pivot end of lever described in the pivot joint of described hub switch side, described working end can be accepted to be driven, is provided with a holding part between described hub switch side and described working end;
A locator, described locator comprises a spacer and an elastic component, described elastic component is located at described holding part, described spacer one end hooks and is located at described the first working head, the described spacer other end compresses described elastic component, and described spacer is provided with Yi Ge location division between two ends, and described locator can change in primary importance and the second place, described locator is positioned at primary importance, the positioning tooth of lever described in the clip of described location division; Described locator is positioned at the second place, and described location division departs from described positioning tooth, and described the first working head and described lever can be pivoted relative to each other.
The beneficial effect that the technical scheme that the embodiment of the present invention provides is brought is: by pivotable align member is set, make the working head of instrument and the lever adjustment angle that can be pivoted relative to each other, preferably tool operation angle is provided; Align member is simple in structure, meets the requirement of light weight, and without extra member fixed locator, allows the locator can rapid-assembling, thereby can really reduce production costs and produce the time; Can utilize locator to carry out slide, be easy to control, meet the requirement of easy operating simultaneously.
