Abstract

The utility model provides a lantern ring spanner, which comprises a spanner and a plurality of lantern rings, wherein the spanner is in a rod-shaped structure, one end of the spanner is provided with an opening, the opening is in a shape of a half of a regular hexagon, the integral shape of the spanner is similar to a fixed spanner, the inner sides and the outer sides of the lantern rings are respectively in a regular hexagon shape, the outer diameter of the largest lantern ring is the same as the diameter of the opening of the spanner, the outer diameter of the second largest lantern ring is fit with the inner diameter of the largest lantern ring, the inner ring is fit with the outer diameter of a next stage of lantern ring, the rest can be done in the same manner until the smallest lantern ring, the inner diameter of the smallest lantern ring is fit with the dimension of a common small-dimension screw cap, and through holes are arranged in corresponding positions of each lantern ring. Through the implementation of the lantern ring spanner, one lantern ring spanner can adapt to the mounting and the dismounting of screw caps in various dimensions and specifications, meanwhile, several lantern rings can be sheathed together, and the carrying is convenient.

Description

A kind of collar spanner

Technical field

The utility model relates to a kind of spanner, particularly a kind of collar spanner that goes for the dismounting of multiple dimensions nut.

Background technology

Present spanner generally includes back-up wrench, monkey wrench and box spanner, and back-up wrench is every to have fixing opening to spanner, the corresponding fixedly nut dismounting of specification, and the nut of different size need use the back-up wrench dismounting of plurality of specifications; Monkey wrench can be regulated opening size, but the adjusting nut of monkey wrench and the gap between the tooth bar, and the opening that has determined monkey wrench all the time can not binding nut, in the time need carrying out the dismounting than great to nut, damages nut easily; Box spanner has overcome the defective of monkey wrench, but volume and weight is all bigger, is not easy to carry.

The utility model content

The purpose of the utility model provides a kind of being easy to carry, and can be applicable to the collar spanner of multiple dimensions nut dismounting, to solve the deficiency of prior art.

The purpose of the utility model is achieved in that a kind of collar spanner, comprises a spanner and a plurality of collar, and spanner is a rod-like structure; One end has opening, and opening shape is orthohexagonal half the, and opening size and common BIG SIZE NUTS coincide; The global shape and the back-up wrench of spanner are similar, are regular hexagon inside and outside the collar, and maximum collar external diameter is identical with wrench opening; Usually less than 2 millimeters of external diameters (matching with the size of the common different size nut size of successively decreasing), inferior big collar external diameter and maximum collar internal diameter coincide internal diameter, and internal diameter matches with next stage collar external diameter again; By that analogy; Up to the collar of minimum, the internal diameter of the minimum collar and common small size nut coincide, and have the hole of a perforation in the corresponding position of each collar.

During use, select the suitable collar to be enclosed within on the nut that needs dismounting, the bigger collar of suit on this collar up to putting the maximum collar, blocks maximum collar outer with wrench opening again, pulls spanner, just can realize the dismounting to nut; Not the time spent, the limit that each collar is had the hole is corresponding, overlaps successively with the mode that big cover is little, and the hole of passing perforation with cord is fixed as one a plurality of collars, is easy to carry.

Through implementing the utility model, can make one can be applicable to the dismounting of multiple dimensions nut, nut is stressed evenly, and is not fragile, and simultaneously, but a plurality of collar suit is easy to carry also together.

The utility model is further described through embodiment below in conjunction with accompanying drawing.

The specific embodiment

Embodiment 1

A kind of collar spanner is characterized in that: comprise a spanner 1 and a plurality of collars, spanner 1 is a rod-like structure; One end has opening, and opening shape is orthohexagonal half the, and opening size and common BIG SIZE NUTS coincide; The global shape and the back-up wrench of spanner are similar, are regular hexagon inside and outside the collar, and the maximum collar 2 external diameters are identical with wrench opening; The inferior big collar 3 external diameters and the maximum collar 2 internal diameters coincide; Internal diameter and the little collar 4 external diameters match, and the internal diameter of the little collar 4 and common small size nut coincide, and the hole 5 of perforation is arranged in the corresponding position of each collar.

Need to prove that present embodiment is a kind of embodiment of the utility model, the quantity of the collar does not receive the restriction of embodiment in the utility model actual production.

Claims

1. a collar spanner comprises a spanner and a plurality of collar, and spanner is a rod-like structure; One end has opening, and opening shape is orthohexagonal half the, and the global shape and the back-up wrench of spanner are similar; It is characterized in that: also comprise a plurality of collars, be regular hexagon inside and outside the collar, maximum collar external diameter is identical with wrench opening; Inferior big collar external diameter and maximum collar internal diameter coincide, and internal diameter matches with next stage collar external diameter again, by that analogy; Up to the collar of minimum, the hole of perforation is arranged in the corresponding position of each collar.
