CN2106045U - Multifunctional spanner - Google Patents

Abstract

The utility model discloses a multifunctional retainer ring spanner, which is used for mounting and dismounting an opened spring ring and comprises a normal spanner body and a spanner jaw. The multifunctional retainer ring spanner is characterized in that a spanner needle pair which can conveniently separated from the spanner jaw is arranged on the spanner jaw; the end part diameter of the spanner needle is corresponding to the hole diameter of the two ends of the opened spring ring. The retainer ring spanner gathers the functions of inner and outer retainer ring spanners into one body and can also be used as a normal wire cutting spanner. The specification of the retainer ring spanner can be reduced much, which is helpful to reduce cost.

Description

Multifunctional spanner

The utility model relates to a kind of hand tools that is used to assemble, dismantle circlip.

In mechanical device often with circlip as back-up ring, be used for each class bearing the location or to have displacement in addition, parts are spacing, but adorn, then need when tearing circlip open according to being the monoblock type retainer pliers that the outer back-up ring or the function of inner shield ring and inside and outside back-up ring specification adopt different specific jaws, so just need to make the retainer pliers of a lot of specifications, be unfavorable for reducing cost.

The utility model purpose provides a kind of multi-functional retainer pliers that integrates inside and outside retainer pliers function.

The utility model purpose is to realize like this, the hand welding that includes caliper 1, jaw 2 of routine is improved, improvement place is the pincers that can separate with jaw easily to be housed at 3 on jaw 2, and the aperture at its end diameter and circlip two ends adapts.

Manual retainer pliers after the improvement has the function of conventional pincers, and no matter adorns, tears open the inside and outside back-up ring of circlip type, only needs to change different pincers at using same on pincers, and the retainer pliers specification can reduce manyly like this, helps reducing production costs.

Described in detail below in conjunction with accompanying drawing.

Fig. 1 is a kind of example structure schematic diagram of retainer pliers.

Fig. 2 is that Figure 1A is to view.

Fig. 3 constructs view for Figure 1A to another kind.

Fig. 4 is that clamp at schematic diagram for the garden cylindricality garden handle, end.

Fig. 5 is that square handle, end are that the crotch clamp is at schematic diagram.

Fig. 6 is that garden handle, end are to have the pincers of gradient transition region at schematic diagram.

Fig. 7 is that garden handle, end are to have the pincers of conical transition zone at schematic diagram.

Fig. 8 is equipped with the retainer pliers structural representation of compression spring for the caliper lower inside.

Fig. 9 is shaped on the groove schematic diagram for jaw, for the B of Fig. 8 to view.

Embodiment one:

The jaw top that includes the hand welding of conventional caliper 1, jaw 2 is processed square hole or hole, garden; in the hole, load onto the pincers that can separate with pincers worker easily at 3; single pincers pin can be made into integral body or is made up of shank and end; shank shape garden shape or square and jaw top-portion apertures match; the pincers needle end part is garden cylindricality or crotch shape (seeing Fig. 4, Fig. 5); the aperture at the split ring ring two ends of its diameter and different size adapts, and caliper closes up inwards or outwards opens and promptly can be used as inside and outside retainer pliers and use.Hole on the jaw can process as required in jaw 2 left and right or upper and lower both sides, and pincers are fixed at available screw.

Embodiment two:

With embodiment one difference is to be equipped with compression spring 6 in the caliper lower inside, makes dress, the use of the amount of tearing open is many, diameter is big inner shield ring more convenient.Can adorn on the jaw pincers that have gradient or conical transition zone between end and the shank at 4,5(sees Fig. 6, Fig. 7), in order to improve pincers needle end part stress state.Be shaped on groove in the jaw side, promptly can be used as conventional combination pliers and use.

Claims (3)

1, a kind of multi-functional retainer pliers that can be used to assemble, dismantle the conventional caliper 1 of including of circlip, jaw 2, it is characterized in that being equipped with the pincers that can separate with jaw easily at 3 on jaw, the aperture at pincers needle end part diameter and circlip two ends adapts.

2,, it is characterized in that being equipped with compression spring 6 in the caliper lower inside by the described retainer pliers of claim 1.

3, by claim 1 or 2 described retainer pliers, it is characterized in that clamping needle end part is crotch shape.
