Abstract

The utility model discloses a demounted handle of multifunction implement which is used for handwork. When the demounted handle is provided with various working parts of different shapes, types and specification; the utility model can be used as a steel saw, a board saw, an awl, a screwdriver, a nut assembly and disassembly tool, a kitchen knife, a bread knife, a files, a drilling tool, a woodwork scribing glass ruler, a walking stick, a plastics shearing knife, etc. When the demounted handle is provided with various symbol working parts, the utility model can be used as a toy for children to know tool, use tool and create tool.

Description

Demounted handle of multifunction implement

The handle for tool of using when the utility model is handwork.

Existing combination tool handle can only the single shape of clamping workpiece, as the screwdriver of garden column, and require the diameter dimension of garden post more unified.Other needs the instrument of handle still handle will be installed as cutter, saw etc.Make combination tool contain long-pending big, cost is high, inconvenient.

The purpose of this utility model provides the handle of a kind of energy clamping column or flat-shaped workpiece.Be used to do the handle of apparatus such as screwdriver, file, awl, hacksaw, bladed saw, small-sized hole brill, metallic tape, big or small fruit knife, bread knife, walking stick.And the diameter of column and the thickness of flat-shaped there is very big accommodation.A handle has extremely wide purposes, when the workpiece of giving the handle for tool main body with various difformities, type and specification, the utility model just becomes cut a piece of glass chi, walking stick, plastics of hacksaw, panel saw, awl, screwdriver, nut handling instrument, kitchen knife, bread knife, file, boring bar tool, carpenter and cuts instruments such as stroke cutter.When being particularly useful for the operation of resident's homecraft, the situation that the shape of workpiece, size are unified not to the utmost.As some symbolistic workpieces are provided, and then can be as children work instrument and implement of knowledge, tool using, create the handle toy of instrument.

The main part of handle for tool with nonmetal or metal (as ABS, engineering plastics, enhancing nylon or other high molecule plastic; Also can be with hard wood, glued board or metal) to make, shape has two kinds of selections.

First kind of shape: during handgun shape, the cross section of gun barrel is c-shaped, and the major axis of C shape is definite like this: holding gun barrel sometimes is operating type, so conveniently to hold, comfortable is good.Along gun tube axis T-slot is arranged, promptly the rifle head end is shallow, and small of the stock end is dark, becomes the T shape cavity of band gradient.T shape cavity is to determine like this: (connecing the 2nd page down)

With the thickness of the flat-shaped of the diameter of the column of workpiece and workpiece, considering simultaneously to have preferable self-locking performance.The small of the stock is to determine like this: holding the small of the stock sometimes is operating type, so conveniently to hold, comfortable is good.The processing of parallel small of the stock face can be inserted the slot of hacksaw blade in the bottom of the small of the stock, and processing one little screw on the vertical small of the stock parallel surface appropriate location is made the auxiliary fixed mechanism of workpiece such as pinning hacksaw blade.Be embedded in the structure of easy loading and unloading parts at the T-slot of handle for tool main body.In the utility model, adopted T shape cavity and the wedge type block and the bar structure for sleeping in of band gradient, realize the clamping workpiece.For making the effective clamping of workpiece in T-slot.Do crude processing in the T-slot bottom, the frictional force when increasing the clamping workpiece.Wedge type block is to make skewback with T-slot gradient unanimity on the handle for tool main body with rigid material (as medium carbon steel).Two groups of tooth bars are arranged on two parallel faces, the cuboid of the V-shaped groove of one 120 degree in another upper edge, plane axis protrusion proper width arranged on an inclined-plane.In the appropriate location of handle for tool main body C shape gun barrel, the bar that crouches is installed, this bar for sleeping in respectively with a certain tooth bar engagement of wedge type block, to drive moving of wedge type block, play fastening locking action.Two tooth bars of wedge type block mesh with bar for sleeping in respectively, two kinds of different working clearance scopes are just arranged, to adapt to difformity, the workpiece of type and specification.In order to guarantee the tooth bar movement locus of wedge type block, adorn an elastic component (as spring steel plate) in the T-slot bottom, after being driven plain, elastic component do not exceed the T-slot base plane, and elastic component acts on the moving face of wedge type block.

When the handle for tool main body is made second kind of shape: during C-shape column shape body, be same as the C shape gun barrel part of handgun shape, promptly the handle for tool main body of handgun shape deducts small of the stock hand portion.This shape is for to not needing the clamping hacksaw, and bladed saw etc. design in the time of will assisting the workpiece of fixed mechanism, and purpose is to reduce cost.

To with the nonmetal handle for tool main body that is processed into, can consider with hub plate in hard rigid material (as the light sheet) processing one in T-slot.

Compare with some known combination tool detachable handles, the utility model possesses these outstanding advantages at least: the adaptability to the shape of workpiece, kind, specification has very quantum jump; Very big to operation type accommodation; Simple in structure; Comfortable during operation, convenient, laborsaving, work is renderd a service high.

As follows, with reference to an embodiment of the present utility model, accompanying drawing is done an explanation:

Fig. 1: the 1st, wedge type block, the 2nd, elastic component, the 3rd, the bar that crouches, the 4th, the bar axle that crouches, the 5th, the handle for tool main body, the 6th, the nut pin, ratio is 1:1.

Fig. 2: be the upward view of handle for tool main body, Fig. 3: be the right view of handle for tool main body, Fig. 4: be the front view of handle for tool main body, Fig. 5: be the left view of handle for tool main body, Fig. 2-Fig. 5 ratio is 1:2.

Fig. 6: be the right view of wedge type block, Fig. 7: be the front view of wedge type block, Fig. 8: be the vertical view of wedge type block, Fig. 9: be the left view of wedge type block, Fig. 6-Fig. 9 ratio is 1:1.

In the practicality, the utility model should the various workpieces of corresponding outfit.Get needed workpiece during operation, according to the shape of workpiece, (as workpiece is column to the relevant work face of selection wedge type block, adopts wedge type block to have the face of V-shaped groove to make the clamping face, in the column embedding V-shaped groove with workpiece; As workpiece is plates, adopts the convex surface of wedge type block to make the clamping face), insert in the T shape cavity.Insert workpiece, the turn bar that crouches, clamping workpiece.Otherwise draw off workpiece.
