Abstract

The utility model discloses a hand tool of a pair of multi-purpose steel wire pliers, is particularly suitable for mechanics to use for maintenance, the multi-purpose steel wire pliers has the functions of a hand vice, a screw driver, a spanner and an awl when the inner sides of the two handles are respectively provided with a connection member, when the clamping workpiece of the handle is grasped and the position of the two connecting members fixed by screws is screwed tightly, and then the handle is fixed and the pliers can be used as a clamp when the pliers is held in clamping state. The terminal ends of the handle can be respectively made into screw driver edges which like the Chinese character 'yi' and 'shi', the upper lip and the lower lip of the pliers mouth are correspondingly opened a V-shaped groove with an intersection angle of 20 DEG, a taper point and a taper hole are arranged in the inner side of the handle and the inner side of the handle is near to the centre shaft, and the handle can puncture hole when being opened and closed.

Description

Multi-purpose steel wire pliers

The utility model belongs to the hardware ﹠ tools field, especially is suitable for mechanic and keeps in repair use.

In the prior art, cutting pliers are made of pincers handle, jaw and axis, can only press from both sides flat board, workpiece, cut-out steel wire, and its middle part is that purposes is narrow, and when handling the work of using the cutting pliers clamping, hand is the grasping forceps handle all the time, and it is laborsaving to be not so good as hand vice.

The purpose of this utility model provides a kind of purposes broad, and can replace the cutting pliers of using of hand vice more.

The purpose of this utility model is achieved in that how to constitute with the axis of cutting pliers by lower plier handle in last lower plier handle, jaw, the connection, be characterized in a connector respectively being arranged in inboard, last lower plier handle handle position, connector is affixed by screw, behind clamping work pieces, tighten the screws can not move connector, thereby makes the pincers handle can not opening and closing, what keep holds clamped condition, plays the hand vice effect.Two pincers handle handle ends make in-line respectively and cross screw is criticized sword, and all are screwed with the sword cap, make cutting pliers increase the screwdriver function.In the inboard of handle, an awl point and the taper hole corresponding with it are arranged near axis.The jaw upperlip becomes 1 ° of-2 ° of angle with labial surface, promptly 2 °-4 ° of jaw angles and on upperlip each correspondence to have an angle be 120 ° V-type groove, be used for nutting, have the spanner function.

The utility model has the advantages that: realized the many usefulness of pincers, can serve as hand vice, screwdriver, spanner and awl and use, easy to use, be suitable for.

Below in conjunction with accompanying drawing the utility model is described in detail.

Fig. 1 is that of the present utility model first implemented structure diagram.

Fig. 2 is second of the present utility model and implements structure diagram.

Fig. 3 is the 3rd of the present utility model and implements structure diagram.

Fig. 4 is that Fig. 3 is along the tooth bar cross section view.

Referring to Fig. 1, the pucellas of using by last lower plier handle (1 more, 2), the axis of lower plier handle (3) constitutes in the connection, in inboard, last lower plier handle handle position a slide plate (5 is arranged respectively, 6) connector of making, wherein slide plate (5) both sides are rolled up long trough, so that slide plate (6) slides within it, slide plate (5, elongated hole is all arranged 6), with pincers handle (1,2) opening and closing, slide plate (5,6) slide mutually, screw (7) is used for fixing slide plate (5,6) position is by slide plate (5,6) connector that serves as its role is to when serving as the hand vice use, the pincers handle (1 of holding with a firm grip, 2) screw screw (7) simultaneously, the position of fixing jaw (4), keep the clamped state of workpiece, rather than held with a firm grip all the time with hand and to keep clamped condition, played the hand vice effect.Pincers handle (1,2) end is made " in-line " and " cross " screwdriver sword (9,8) and is screwed with sword cap (10) on it, back out the sword cap during use, if pincers handle (1,2) external insulation sleeve is made by the material of good springiness, also can not back out sword cap (10) but be screwed into sword cap (10) always, compress insulation sleeve and expose screwdriver sword (9,8), twist back sword cap (10) again with finishing, elastic insulated cover return, so promptly convenient, can prevent that again sword cap (10) from losing, pincers handle end also can be made interior hexagonal, awl, drill bit etc.Awl point (11) is used for dazzling, and taper hole (12) is used for holding sodium awl point (11), and angle is 120 ° of V-type grooves, be used for twisting bolt, nut is convenient, has had the effect of spanner.Jaw (4) upperlip and labial surface angle are 1.5 °, and promptly the jaw angle is 3 °, press from both sides flat part like this and can increase contact area, folder steadily firmly.

Referring to Fig. 2, the connector between the last lower plier handle (1,2) is made of screw rod (15) framework (16) and nut (14), and screw rod (15) passes the free end of framework (16), when needing the fixed position, and fastening nut (14).

Referring to Fig. 3, connector between the last lower plier handle (1,2) is made of tooth bar (17) and framework (18), tooth bar (17) penetrates framework (18) free end and is set on the framework (18) referring to Fig. 4 monodentate (19), and root has spring (20), make monodentate (19) scalable, the direction of monodentate (19) tooth is opposite with tooth bar (17), and when monodentate (19) meshed with tooth bar (17), tooth bar (17) only advanced not move back.In tooth bar (17) root and pincers handle (1) contact position, having a little spring to withstand tooth bar (17) end face holds on the upper side, make tooth bar (17) be subjected to a downward-sloping power,, be not subjected to connect restriction and influence so that normally use cutting pliers hour rack (17) and monodentate (19) to break away from engagement.When using as hand vice jaw (4) is magnified, the turn of the screw (21) is as the criterion the engagement of monodentate (19) and tooth bar (17), clamping work pieces, because of the direction of their teeth is opposite, tooth bar (17) only advances not move back, hold with a firm grip and clamp handle (1,2), then realize auto lock.
