Description

A kind of new multi-purpose is screwed pincers

Technical field

The utility model relates to the instrument instrument field, more particularly relates to a kind of novel multipurpose and screws pincers.

Background technology

At present, tonger is of a great variety on the market, be used for screw nut and be screwed into the tonger of back-outing or rotating use, generally constitute, the recessed stripe shape decorative pattern of the row's of setting shape on the jaw of handle upper end by two hinged handles, with fixedly gripping, this in actual use because the special size of some screw nut, not enough firm stable when gripping, the jaw working face is the line style butt joint, and is often smooth easily; Just like application number is 97233072, the applying date is on 05 10th, 1997, denomination of invention is screwed the patent application of pincers for the bone surgery screw gets stuck, it is linked together by joint shaft by two of mutual correspondence, every respectively by binding clip, close knothole, bend, handle and form, binding clip mouth inside has the semilune of mutual correspondence damaged, its inner face has horizontal shape ditch ridge shape striped, this handle of screwing pincers is higher than clamp head part, and side-looking is the table fork shape, and the binding clip arm of force accounts for the 1/7-1/5 of apparatus length overall.This patent has that it is simple in structure, easy to use, but it is often used for larger-size screw nut etc., is adding when holding slidingly easily, only is used for vertical clamping, has used limitation, and its purposes is more single in addition.

The utility model content

The purpose of this utility model is exactly in order to solve the deficiency of prior art, and a kind of clamp screws nut, the new multi-purpose simple in structure, that result of use is good of making things convenient for that provides screwed pincers.

The utility model is to adopt following technical solution to realize above-mentioned purpose:

This new multi-purpose is screwed pincers, by two mutually corresponding tong arms, connect and compose by the reel on the tong arm between the two, the reel upper end of tong arm is a binding clip, it is characterized in that: the equal correspondence of this binding clip joint face jaw is provided with camber list groove or the dual-cavity that is used for socket screw or nut, binding clip outside working face is set to the inclined-plane, and this camber dual-cavity is positioned at jaw tip central authorities and both sides and vertical with working face; The junction of this tong arm is set to arc edge docking structure.

As further specifying of such scheme, be provided with a through hole on the opposite of described tong arm lower end, be outside equipped with screw rod, be enclosed within the hold-doun nut on the screw rod with through hole between this through hole.

The level angle of described binding clip skew back face is 60 °-70 °.

Described tong arm below is the arm of force, and the arm of force is the Wave-shaped structural of opposition, and the length of the arm of force is 6～7 times of binding clip.

Described tong arm outward also can sheathed grip, and health when being used to use and needs such as comfortable also are communicated with and have the hole being enclosed within the through hole.

The beneficial effect that the utility model adopts above-mentioned technical solution to reach is:

1, the utility model is screwed into to back-out to use and designs for being specifically designed to slipped screw, bolt etc., special camber dual-cavity in the binding clip, meet mechanics principle, greatly strengthen steadiness when clamp is held and the stability in when rotation, thereby can take out slipped screw, bolt etc. easily in use; When toppling over caliper, when the skew back face structure clamp screws of use binding clip is operated, clamp core and horizontal plane are angled, there is certain distance between pincers handle and the horizontal plane, moment in the time of promptly can significantly promoting rotation, also more convenient operation is applicable to the situations such as the stage of tightening at last that the operating space is limited, need huge twisting resistance and screw to be screwed into; Also have the arc design of binding clip, stable when also helping the clamping rotation, sideslip, crooked phenomenon when not being prone to the traditional tonger clamp screws rotation of picture in conjunction with working face; The set bolt that is provided with on the arm of force in addition more can provide good stable chucking power, is being screwed into, is back-outing particularly suitable when needing simultaneously vertically pressurization or traction; Pincers handle undaform design convenience grasping increases the comfortableness when using.

2, because only needing clamp screw (bolt) nut edge to surpass the 0.5mm degree of depth, these pincers can realize the stable operation of back-outing that is screwed into, and most of orthopaedic screw (bolt) nut edge all has and is higher than steel plate or surface of bone and surpasses most of screw in 0.5mm height, the daily life and also all expose the nut edge and surpass 0.5mm, this highly can clamp for this reason the operating space is provided, so these pincers for screw, bolt be screwed into back-out the operation actual effect very obvious, be applicable to the situation that screw (bolt) nut skids or the no supporting screw of screw (bolt) is split; In addition, because these pincers can stablized vertically pressurization or traction of realization on the basis of clamp, therefore, even screw nail road skids, these pincers also can be easily with its taking-up, and no matter in daily life is still performed the operation, skid the situation that can't continue to be screwed into when running into screw nut, use these pincers need not change screw, directly its pressurization is screwed into, saves time and resource, this is these pincers outstanding feature.

3, the utility model is made, and to screw wrench structure simple, and production cost is low, and is practical, and the scope of application is wide, can good use value be arranged as aspect tongers such as medicine equipment and hardware ﹠ tools.
