Description

Multi-functional retainer pliers

The utility model relates to a kind of hardware ﹠ tools, is a kind of axle is used back-up ring with the hole pliers that mounts and dismounts.

This in the prior art instrument is simple function, split manufacturings, and for example external circlip plier just can only be used for the installation and removal of shaft block ring, and internal circlip plier also can only be used for dismounting and the installation of hole with back-up ring, does not have the compound pliers of multi-functional.

The purpose of this utility model provides that axle is unloaded in the installation and dismantling of a kind of Jian, back-up ring two kinds of functions in hole are a kind of novel hardware ﹠ tools of one.

Scheme of the present utility model is: a kind of multi-functional retainer pliers that is combined by multiple interchangeable binding clip and single pincers handle.The structure of pincers handle is removed scissors cutter head remaining part later on just as a scissors, and it includes the pincers leg of two symmetries, and they are connected to hub branch structure by the pivot pin of a band center through hole.Be the boundary with the pivot pin the place ahead of described pivot pin pivot point have a pair of before inserting column, inserting column is disposed in respectively on two opposite sides of vice body with back inserting column before there is being a pair of back inserting column at the rear of described pivot pin pivot point, is described.There is a pair of torsion spring fixing hole at rear portion at described back inserting column.Its binding clip has the structure that is similar to the scissors head, two and half binding clips is arranged each other by the pin formation hub branch structure that is solidly fixed of a band center through hole.That the front end of binding clip has respectively is straight, 45 ° of bendings, 90 ° of difformities such as bending, and it is jaw foremost.Jaw is inserted into and in two earholes of back-up ring it is opened or draw in and take out in use.Binding clip is the boundary with its pivot point, and a pair of preceding through hole is arranged up, and a pair of back through hole is thereunder also arranged, and described through hole is to match with the back inserting column with the aforesaid preceding inserting column that is fixed on the pincers handle two side faces to constitute removable lining the connection.When matching with the preceding inserting column of pincers handle, the preceding through hole of binding clip just constitutes an external circlip plier when being connected.When being connected with the back inserting column that clamps handle, the back through hole of binding clip just constitutes an internal circlip plier.

Binding clip is achieved in that because binding clip constitutes fixedly connected pivot fulcrum pin with 2 half parts with being connected of pincers handle and all has central through hole with the pivot fulcrum pin that clamps handle, binding clip is being clamped handle when interconnecting, need pass binding clip and the through hole that clamps handle pivot moving axis pin with a lock pin, the two is solidly fixed.Described lock pin one end is the cap head, is provided with a stage clip in cap head inboard, in the end opposite of cap head a movable locking plate is arranged.Described movable locking plate is the sheet metal of a band open-work groove, and lock pin one end that cooperates with it longitudinally has an open slot, the wide thickness that is slightly larger than described locking plate of the seam of described open slot, and the width of described locking plate is slightly less than the diameter of described lock pin cylinder.When locking plate is inserted into the open-work groove that passes locking plate in the opening again with a rivet, the two rivet clasp one is just constituted a movable locking plate that can turn over 90 ° of angles easily.In use, earlier described stage clip is inserted in the end of lock pin, again lock pin integral body is passed the through hole of the pivot fulcrum pin of binding clip and pincers handle, at last with described movable locking plate half-twist angle by the cap head, like this, binding clip and pincers handle the two just propped up and linked into an integrated entity by pivot.When needs transposing binding clip, need only movable locking plate is gone back to 90 ° of angles, make the length direction of movable locking plate consistent with the cylinder length direction of lock pin, just lock pin integral body can be extracted out from the through hole of the pivot fulcrum pin of binding clip and pincers handle, like this, the two is just separable for binding clip and pincers handle.

The utility model has the advantages that:, so become and to realize that binding clip is straight, 45 ° of bendings, the dismounting shaft block ring of 90 ° of bendings and the multi-functional combination retainer pliers of hole usefulness back-up ring because multiple multi-form binding clip can be easily change on the pincers handle.

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

Brief Description Of Drawings:

Fig. 2 is the stereogram of reflection tong head.

Fig. 3 is the stereoscopic-state figure that reflection binding clip and pincers handle are combined into one.

Fig. 4 is the three-dimensional exploded view that reflection connects the latch gear of binding clip, pincers handle.

Fig. 5 is the rotary state of movable locking plate in the reflection latch gear.

Fig. 1 to Fig. 4 of the present utility model is a kind of embodiment of multi-functional retaining figure pincers of straight binding clip.Pincers handles (1) are to connect and compose one by the pivot pin (2) that half of two symmetries clamp with the band center through hole.On each half pincers, be the boundary with pivot pin (2), the place ahead of described pivot pin pivot point have a pair of before inserting column (3); A pair of back inserting column (4) is arranged at the rear of described pivot pin pivot point.On two symmetries, half pincers, inwardly outstanding lug is arranged, on lug, have aperture, have a torsion spring (5) to be connected across the inboard of two and half pincers by described aperture.

Described binding clip (6) also is to be attached to one by half binding clip of two symmetries pivot pin (7) by a band center through hole to be constituted.The front end of binding clip (6) is provided with jaw (8).That the front end shape of binding clip has respectively is straight, 45 ° of bendings and 90 ° of these three kinds of patterns of bending.With pivot pin (7) is the boundary, its place ahead have a pair of before through hole (9); A pair of back through hole (10) is arranged at its rear.Described through hole be with pincers handles (1) on forward and backward inserting column (3), (4) match and constitute removable lining the connection.When the preceding inserting column (3) of through hole before the binding clip (9) and vice body just constitutes an external circlip plier when matching.When through hole behind the binding clip (10) just constitutes an internal circlip plier (as shown in Figure 3) with the back inserting column (4) of pincers handle when cooperating.

For binding clip (6) being fixed on the pincers handles (1), a latch gear (13) is arranged.One end of described lock pin (14) is cap head (11), has an open slot (18) on the end opposite, inserts a flat movable locking plate (12) in described open slot (18), and the groove width of described open slot (18) is slightly larger than the thickness of described movable locking plate (12).The nearly cap head (11) of lock pin (14) is in cap head inboard and is provided with a compression spring (15).One open-work groove (17) is arranged on the described movable locking plate (12).After described locking plate (12) inserts in the open slot (18) of described lock pin (14) by with a pin (16) riveting jail.Pin sheet (12) can be done the rotation (as shown in Figure 5) of 90 ° of angles in open slot (18).When needs are done transposing to different types of binding clip (1), as long as pass binding clip of newly changing (8) and the central through hole that clamps handle (1) pivot moving axis pin (2), (7) with described latch gear (13), the two is conspired to create one, then described pin sheet (12) half-twist angle (as shown in Figure 5), latch gear (13) becomes one binding clip (6) and pincers handles (1) pinning under the elastic force effect of compression spring (15), according to the various combination of inserting column and through hole, can constitute the shaft block ring or the hole back-up ring of different purposes.
