Abstract

The utility model discloses a key ring. The key ring comprises a spiral body, wherein the head end of the spiral body is bent outwards. Compared with the prior art, the key ring has the advantages that since the head end of the spiral body is bent outwards, when a key is strung, the head end of the outward-bent body only needs to be inserted into a key lug without breaking the body, and then old and weak persons can string the key without spending strength, so that the use and the operation are very convenient and fast.

Description

Key-ring

Technical field

The utility model relates to a kind of key-ring.

Background technology

Existing key-ring; Generally comprised spiral helicine body; The key-ring of comparatively robust generally all is to be formed by the harder bonding jumper bending of the quality of thick root; And the head end of body be the inlet of key precession first all is to lean on very closely with body, and the schoolgirl that strength is little is difficult to break inlet into two with one's hands, and is very inconvenient.

The utility model content

The utility model provides a kind of key-ring, and it can solve the problem that the inlet difficulty of existing key-ring key precession is first broken into two with one's hands.

In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is: it comprises spiral helicine body, and the head end of said helical form body outwards bends.

In the technique scheme, scheme is more specifically: the end of said helical form body bends inwards.

Owing to adopted technique scheme, the utility model compared with prior art has following beneficial effect:

Because the head end of helical form body outwards bends, when wanting in the key precession body like this, only need getting final product in the body head end of the outside bending insertion key ear; No longer need break body into two with one's hands; The old and the weak all can go here and there key, does not take efforts, and uses and operates all very convenient quick.

Description of drawings

Fig. 1 is the structural representation of the utility model

The specific embodiment

Below in conjunction with the accompanying drawing instance, the utility model is done further to detail:

The utility model as shown in Figure 1, it comprises spiral helicine body 1, the head end 1-1 of helical form body 1 outwards bends; When the string key, only need no longer need break body into two with one's hands like this getting final product in the body head end of the outside bending insertion key ear; The old and the weak all can go here and there key, and the terminal 1-2 of helical form body also bends inwards, and head and the tail all can be gone here and there key like this; Do not take efforts, use and operate all very convenient quick.

Certainly; Above-mentioned explanation is not to be the restriction to the utility model; The utility model also be not limited in above-mentioned for example, variation, remodeling, interpolation or replacement that the technical staff in present technique field is made in the essential scope of the utility model also should belong to the protection domain of the utility model.

Claims

1. a key-ring comprises spiral helicine body, it is characterized in that: the head end of said helical form body outwards bends.

2. key-ring according to claim 1 is characterized in that: the end of said helical form body bends inwards.
