Abstract

The utility model discloses a spring clip, the left and the right handles of which are articulated by a fulcrum. The extension arms of the two ends of the spring which is on the fulcrum acts on the shank of the handle to form a clamping state of the part of the mouths of the left and right handles. And a pair of movable grips which are ready-replaced and which can adjust a gripping surface automatically are arranged at the part of the mouths of the left and right handles. The movable grips have gripping surfaces in different shapes. The upper and lower surfaces are kept in parallel in gripping and the object which is gripped is uniformly stressed. A user can choose the grip in accordance with the shape of the gripped object and can dismount the grip conveniently. The utility model is applicable to different occasions and has a wide scope of application.

Description

Spring clip

Technical field

The utility model relates to the hardware ﹠ tools class, especially a kind of spring clip.

Background technique

In plant produced, repairing, in the family daily life, all be unable to do without the five metals gadgets, as industries such as upholster, carpenter's woodenware, Mold Making, machine-building, the hardware ﹠ tools of bound picture spring clip and so on, for example the carpenter often needs to be fixed as the part in doing bonding operation, especially work as the bond shape not simultaneously, just need a kind of spring clip of specific chuck structure.

Summary of the invention

Technical problem to be solved in the utility model is exactly to need to provide a kind of spring clip that has specific chuck for specific work post.

The utility model solves the problems of the technologies described above the technological scheme that is adopted: spring clip, left and right handle is hinged and connected with fulcrum, suit spring on the fulcrum, the two ends adjutage of spring acts on the shank of handle, form left and right handle oral area clamped condition, the oral area that it is characterized in that described left and right handle be provided with a pair of can regulate automatically clamp face, the active chuck of disassembling, assembling and replacing at any time.

Compared with prior art, the utility model is provided with at the handle oral area can regulate active chuck clamp face, that can change at any time automatically, can keep top and bottom parallel during clamping, make caught object stressed evenly, the user selects chuck according to the shape of held object, disassembling, assembling and replacing is convenient, is suitable for different use occasions, and using scope is big.

Embodiment

Referring to Fig. 1-10, the left and right handle (1) of spring clip is by the plastic material molding and forming of different colours, and the handle cross section is " U " type, opening in opposite directions inwardly, wall thickness is consistent substantially, profile arc transition nature grips comfortablely, meets ergonomics.Be provided with transverse stiffener rib (5) and longitudinal rein forcement (6) in the handle, gain in strength long service life.

Left and right handle (1) is hinged and connected with fulcrum (8), this fulcrum is made up of the screw and nut of head "+" word groove, it is extremely convenient that handle is changed in dismounting, be set with spring (7) on the fulcrum, the two ends adjutage of spring acts on the inboard of handle shank, form left and right handle oral area clamped condition, to realize the purpose of clamping object.

The oral area of left and right handle is provided with a pair ofly can regulate active chuck clamp face, that can change at any time (3) automatically, clamp face is parallel up and down to keep, make caught object stressed evenly, and this active chuck dismounting changes the outfit conveniently, for this reason, the symmetrical position of left and right handle oral area is provided with the little axle (4) of 2 open-work grooves (2) and disjunctor.And active chuck is made up of clamp face (10) and 2 fork pin (9), and the fork pin is provided with " V " type round bottomed vessel (12) that matches with little axle.After active chuck was pitched left and right handle oral area, two fork pin entered the open-work groove, and swung work around little axle and regulate clamp face automatically under the clamping force effect, made held object keep top and bottom parallel and stressed even.

For adaptation is held the difformity needs of face, the clamp face of active chuck (10) is different, and present embodiment provides 3 kinds of clamp face structures, Fig. 4-6 is scheme 1 chuck structure, clamp face (10) is the plane, and the plane is provided with the small boss (11) that matrix is arranged, and is applicable to the plane clamping; Fig. 7-9 is scheme 2 chuck structures, and clamp face (10) is symmetrical inclined-plane, is applicable to the clamping of symmetrical inclined-plane; Figure 10 is scheme 3 chuck structures, and clamp face (10) is a cambered surface, is applicable to the cambered surface clamping.The chuck of

scheme

1,2,3 is looked the shape of clamping object and is distinguished applied in any combination mutually, also can be designed to the chuck of other shape, the user can select as required, makes a spring clip have purposes widely, because the chuck disassembling, assembling and replacing is easy, so liked by the user.
