A kind of round nut dismounting special spanner, is characterized in: comprise handle and clamp assemblies; Described clamp assemblies comprises panel seat and two claws, panel seat is provided with two installing holes, at least one installing hole is slotted hole, two claws are vertically packed in outside the same end face of panel seat respectively by two installing holes are detachable, the cross section that two claws are positioned at the part outside panel seat end face is square, and the square aperture on itself and round nut matches; One end of handle and the side of panel seat affixed.This special spanner structure, to make with round nut direct acting retained part and hold force part spatially to form certain distance, like this, when dismounting round nut, axially the front end of claw can be deep in bearing block along bearing block, and handle portion is positioned at outside bearing block, like this by driving handle part, just can realize tightening and loosening of round nut easily, there is simple, convenient advantage.

Description

A kind of round nut dismounting special spanner
Technical field
The utility model relates to the aid of machinery equipment assembling, particularly a kind of round nut dismounting special spanner.
Background technology
Round nut is generally used in bearing expansion set and axle head, is used for locking the effect that bearing plays location.At present, usually adopt Hook wrench to twist round nut, realize the locking of round nut and loosen.But in the design of some special constructions, need round nut to be deeply installed to inside bearing block.For such structure, common Hook wrench is adopted to be difficult to tighten round nut when actual installation.
Summary of the invention
The utility model provides a kind of when round nut needs deeply to be installed in bearing block for solving in known technology the technical problem that exists, and can realize round nut tightens, and the round nut dismounting special spanner that the round nut that can meet plurality of specifications uses.
The technical scheme that the utility model is taked for the technical problem existed in solution known technology is:
A kind of round nut dismounting special spanner, is characterized in that: comprise handle and clamp assemblies; Described clamp assemblies comprises panel seat and two claws, panel seat is provided with two installing holes, at least one installing hole is slotted hole, two claws are vertically packed in outside the same end face of panel seat respectively by two installing holes are detachable, the cross section that two claws are positioned at the part outside panel seat end face is square, and the square aperture on itself and round nut matches; One end of handle and the side of panel seat affixed.
The advantage that the utility model has and good effect are:
This special spanner structure, to make with round nut direct acting retained part and hold force part spatially to form certain distance, like this, when dismounting round nut, axially the front end of claw can be deep in bearing block along bearing block, and handle portion is positioned at outside bearing block, like this, by driving handle part, just can realize tightening and loosening of round nut easily, there is simple, convenient advantage.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, handle; 2, clamp assemblies; 210, panel seat; 211, installing hole; 220, claw; 221, the shaft shoulder; 230, locking nut; 240, packing ring.
Detailed description of the invention
For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1, a kind of round nut dismounting special spanner, comprises handle 1 and clamp assemblies 2.Described clamp assemblies comprises panel seat 210 and two claws 220.Panel seat is provided with two installing holes 211, and at least one installing hole is slotted hole.Two claws are vertically packed in outside the same end face of panel seat respectively by two installing holes are detachable.Concrete, the position near one end on claw is provided with the shaft shoulder 221, and this end of claw is shaped with external screw thread.When mounted, the end of thread of claw is inserted in the corresponding installing hole of panel seat by one side end face of follower seat, make the shaft shoulder be pressed on the end face of panel seat, then by the locking nut 230 that is connected with the claw end of thread and packing ring 240, claw is fixedly mounted on panel seat.The cross section that two claws are positioned at the part outside panel seat end face is square, and the square aperture on itself and round nut matches, and namely claw is positioned at the main part outside panel seat is square column structure.One end of above-mentioned handle and the side of panel seat affixed.
The length of the main part that above-mentioned claw is positioned at outside panel seat is arranged according to the actual needs flexibly, in addition, for a set of special wrench, can the claw of supporting many group different sizes, and like this, to meet the dismounting needs of the round nut of different openings size.
Using method of the present utility model:
When using this special spanner, first the distance between two claws is adjusted according to the dimensions of round nut, concrete, first unscrew the locking nut be connected with the claw end of thread, then claw is moved along the slotted hole on panel seat, when distance between two claws is consistent with the distance of two opposed open on the round nut tightened, then tighten locking nut; Then two claws are inserted into respectively in two opposed open on round nut, handle of finally holding with a firm grip, drive panel seat to rotate, just round nut can be tightened in bearing block.
