Abstract
The invention relates to a self-locking open ratchet spanner which comprises a spanner body (3), a clamping foot (4) and a spanner clamp (1), wherein the clamping foot (4) and the spanner clamp (1) are movably connected with the spanner body (3). The clamping foot (4) can slide in a clamping groove (3d) of the spanner body, one end of the spanner clamp (1) is movably connected with a handle (2) and movably connected between the spanner body (3) and the handle (2), the handle (2) drives the spanner clamp (1), and the spanner clamp (1) rotates by taking an outside cambered surface (1a) as a supporting point, so that a nut can be clamped and locked by shortening the distance between the spanner clamp (1) and the clamping foot (4) of the spanner body (3). When the handle (2) reversely rotates, the handle (2) drives the spanner clamp (1) to reversely rotate, the relative distance between the spanner clamp (1) and the clamping foot (4) is increased, and the spanner clamp (1), the clamping foot (4) and the nut can relatively rotate. Compared with the prior art, the self-locking open ratchet spanner can rapidly clamp and unidirectionally lock workpieces with different sizes.
Description
Technical field
The present invention relates to open ratchet wrench used in everyday, relates in particular to adapt to fast the workpiece of different size and the spanner of one-way locking.
Background technology
The open ratchet wrench of available technology adopting, such as No. 03809775.3 patent of Singapore, the disclosed technical scheme of this patent is that the addendum cone of handle drives the matrix cone of upper jaw, forms the ratchet motion with this addendum cone mechanism.Because addendum cone mechanism is opening, therefore inevitable easily laying dust makes mechanism blockage; Because lower jaw adopts screw and U-shaped guide rail to regulate, so the inevitable efficient of this spanner governor motion is lower, and processing difficulties, difficult maintenance.
Summary of the invention
The technical problem to be solved in the present invention provide a kind of simple and reliable for structure, do not need the open ratchet wrench of throwing off from nut;
A further object of the invention provides a kind of spanner, the fastener that has adjustable card base and drive with handle;
A further object of the invention provides a kind of opening lug wrench of the different nuts of quick adaptation of durable and reliable structure;
A further object of the invention provides a kind of convenient for production, safe spanner easy to use.
The present invention solves the technical scheme that the prior art problem adopts:
Design a kind of ratchet spanner, comprising: wrench body, but reaching and the fastener of its flexible connection and the card base of quick adjustment, they consist of the clamping part of nut.Described clamping part binding nut under the handle with its flexible connection drives also can drive the nut rotation, to realize locking.
Compared with prior art, spanner of the present invention can quick adjustment, to adapt to the different size nut; Spanner does not need to come off from nut simultaneously, realizes continuous operation.
Another technical scheme of the present invention is: the spanner fastener can rotate around the wrench body rotating shaft.
Another technical scheme of the present invention is: the spanner fastener can relative motion and self-locking in wrench body.
Another technical scheme of the present invention is: connecting rod makes spanner fastener and card base relative motion under the drive of handle.
Another technical scheme of the present invention is: regulating handle, the relative position of any part and wrench body can change the space of card base and fastener in spanner fastener and the card base, adapts to the different size nut.

The specific embodiment
The invention will be further described below in conjunction with accompanying drawing and embodiment shown in the drawings.
As depicted in figs. 1 and 2, ratchet spanner of the present invention comprises: wrench body 3, and with card base 4 and spanner fastener 1 that wrench body 3 is flexibly connected, this card base 4 can move to adapt to different nuts in wrench body draw-in groove 3d; The end of this spanner fastener 1 and handle 2 are flexibly connected, and are flexibly connected between described wrench body 3 and handle 2; Handle 2 drives described spanner fastener 1, spanner fastener 1 rotates take outside cambered surface 1a as fulcrum, conversion by spanner fastener 1 angle, so that the position between the card base 4 of spanner fastener 1 and wrench body changes, thereby can binding nut etc. workpiece, the nut reaction force acts makes card base 4 and wrench body 3 self-lockings on card base end face 4a, under the continuation rotation of handle 2, drive the nut rotation.When handle 2 reverse rotation, 1 reverse rotation of handle 2 band wrench fasteners, spanner fastener 1 and card base 4 relative positions change, and can relatively rotate with nut.Compared with prior art, the workpiece of the different sizes of spanner of the present invention can be realized fast clamp and can realize one-way locking.
As shown in figure 11, ratchet spanner of the present invention comprises: wrench body 3, and with spanner fastener 1 and the handle 2 of wrench body 3 active buckles, with the connecting rod 6 of spanner fastener 1 and handle 2 flexible connections.This handle 2 drives connecting rod 6 counter motions, described connecting rod 6 band wrench fasteners 1, and spanner fastener 1 and card base 4 relative positions change, and can relatively rotate with nut, needn't throw off from nut
Except above-mentioned preferred embodiment, the present invention still has multiple concrete embodiment.All employings are equal to replacement or equivalent transformation and all technical schemes of forming, all drop within the scope of protection of present invention.
