Description

Clamp with elements of auxiliary tools

The pliers of being furnished with the aid element is a kind of screwdriver that is fitted with, and also can be fitted with the combined hand tool of electroscope, and screwdriver, electroscope are removable tool elements.

Pliers is all formed caliper by handle, chela, and two caliper cross-articulation form, and its structure only has the function of pliers.Use many craft to have pliers, screwdriver, for the normal electroscope in addition that uses of electrician.These tool constructions independently are difficult for equipped the use separately.

The purpose of this utility model is to make the part hand-held tool with the pliers use same period can be fitted to pliers, and a kind of pliers of being furnished with the aid element is provided.

The pliers of being furnished with the aid element is linked to be caliper by handle, chela, two caliper cross-articulation, and its design feature is: the relative face of two chelas of two calipers has side by side, notch relative, open the closing in shape groove to the chela front end face, but the cross sectional form bilateral symmetry of groove, preferably the groove of two chelas is also symmetrical, groove vertically perpendicular to or approximately perpendicular to jointed shaft.Pliers is furnished with screwdriver, and the screwdriver back segment is the plug that the groove when merging with two chelas is pegged graft and cooperated.Groove shape was identical or roughly the same when the shape of general plug merged with two chelas.So just the screwdriver that can be used the same period is fitted to pliers, when the screwdriver plug is inserted pliers and merges in the groove of two chelas, because pegging graft with the groove of merging, plug cooperates, can not move or rotate mutually between the groove of plug and merging is horizontal, pliers is as the handle of screwdriver, and after the plug of screwdriver transferred in the groove, pliers recovered the function of its pliers again.In order to make plug not free longitudinal sliding motion in merging groove, can be equipped with at the groove inwall and bump pearl, the face corresponding with bumping pearl at the plug of screwdriver also can have the hole.The leading portion contact of electroscope is an inserted sheet, and the contact inserted sheet of electroscope can insert between handle and the handle insulation sleeve, makes electroscope can be fitted to pliers, forms the pliers or the screwdriver of band electroscope.

The intersection of two calipers is generally intersected at handle, chela intersection, and is hinged with jointed shaft at infall, and the face that jointed shaft is general relative with two chelas is parallel.A jointed shaft and a caliper can be made one, and another caliper is placed in jointed shaft movingly, forms pliers, as diagonal cutting pliers, flat-nose pliers etc.Chela at pliers has groove, groove is opened at the relative face of two chelas, notch is positioned at the relative face of chela, notch is relative, groove is the system of vertically opening along chela, and the groove of two chelas and example are when two chelas merge, the groove of two chelas is parallel or approximate parallel, vertical or near normal vertical with jointed shaft of groove.One end of groove is to the chela front end face, and to angle, the inclined-plane forms the angle of concane gap as diagonal cutting pliers, and two chela front end faces of flat-nose pliers have relative concave indentation.And the other end of groove can be opened to vertical certain position of chela, as the root or the middle and lower part of chela.The shape of groove will form close trench bottom partial width greater than close slot-open-section width, and just the cross-sectional perimeter of groove will have the part greater than half cycle, forms the groove of closing in or part closing in, and is scarce greater than the circle of half cycle as dovetail groove, oval groove.

The screwdriver of preparation, mainly be cutter head and knife bar part, there is not hilt, the screwdriver back segment is a plug, groove when the shape of plug and two chelas merge matches, and plug inserts the groove that merges, and plug is pegged graft with the groove of merging and cooperated, plug slot is mutually movingly or the size of interference fits to the groove lateral dimension of size and merging, makes the mutual horizontal bidimensional fixed constraint of formation between plug and the chela.But plug laterally cooperatively interacts with the horizontal portion size of groove, preferably all cooperates or most of the cooperation, and the flute profile when promptly the shape of plug merges with two chelas is identical or roughly the same.When two chelas merged, the notch of two chelas connected, and formed the hole of butt joint, as formed the hole of 8 fonts.Plug is meant that with the cooperation of groove lateral part size plug is different with groove shape, but plug has the size at several places identical with groove inwall lateral dimension, and these several places contact with the groove inwall, forms plug and cooperates with the grafting of groove.As groove is when lacking the shape groove greater than the circle of half cycle, the plug cross section can be for merging 8 identical fonts of groove shape with two, also can be the shape of two dovetails butt joint, two jiaos of ends of dovetail cooperate with groove closing in madial wall, perhaps dovetail butt joint recess cooperates with the notch place, forms laterally two-dimentional fixed constraint mutually between plug and the chela.

Groove is the groove of symmetric figure preferably, groove cross section bilateral symmetry, and also the groove of two chelas is preferably symmetrical.The symmetry of groove is the bilateral symmetry of groove, and two chelas is to be the plane of symmetry with the face between two chelas symmetrically, and it is more convenient to make screwdriver peg graft.

The contact of the leading portion of electroscope is made the inserted sheet shape, and inserted sheet can be the folding shape, and the cross section of inserted sheet can be curved, is convenient to insert between pliers handle and the handle insulation sleeve.

Like this, screwdriver, electroscope can be fitted to pliers, and the volume of screwdriver is reduced, be easy to carry and place, and use also more convenient, when using screwdriver or pliers, simultaneously can electrical verification.

Fig. 1 has represented that screwdriver, electroscope are with the equipped schematic diagram together of diagonal cutting pliers.Fig. 2 has represented the structural representation of screwdriver back segment plug, and Fig. 3 has represented that chela has the jaw partial view of dovetail groove, and Fig. 4 has represented the structural representation of the electroscope of outfit.

The angle chela 1 and the handle 2 of this angle pliers are made one, and two calipers, 3 cross-articulation are formed the angle pliers.Respectively have the dovetail groove 4 of a symmetry at the relative face of two angle chelas, two grooves and the example, flute profile is identical, notch is relative, groove is positioned at the horizontal middle part of two chela opposite faces, groove longitudinally an end as for the angle 5 of chela, the other end is as for the root of chela, and groove vertically is approximately perpendicular to jointed shaft 6.The screwdriver 7 back segment plugs 8 that are equipped with are the multiaspect column, and the cross section of plug is identical with the slot cross-section that chela merges, and are the shape of two dovetails butt joint, and plug is identical with two flute profiles that merge, and pegging graft simultaneously with two grooves cooperates.When two chelas merged, screwdriver inserted the two chela grooves that merge by plug, was the screwdriver of screwdriver handle and form with angle pliers handle.Bump pearl 9 at a chela bottom land wall, and have hole 10, after the groove that the plug insertion is merged is interior, do not allow to skid off in corresponding screwdriver plug bottom surface.The contact of the front end of electroscope 11 is the arc inserted sheet 12 of bending, inserts between angle pliers handle and the handle insulation sleeve 13 by inserted sheet, forms the angle pliers that has electroscope.
