Wherein, the outer surface of this protective sleeve is integrated is provided with a plurality of protuberances.

Wherein, this grip part is a prolate shape, and each protuberance is the cone of rhombus, and closely is arranged in the front side and the rear side of this protective sleeve.

Wherein, this wrench body comprises a driving head and a spanner, this driving head and this spanner are the subtend setting, and be divided into the two ends of this wrench body, this driving head is circular, and central authorities are hollow, is provided with ring-like ratchet in the internal perisporium of this driving head, this spanner is concaved with the jaw of a U-shaped, and this grip part is linked to the central authorities of this driving head and this spanner.

Wherein, this grip part is cylindrical, and each protuberance is semicircle, and is set around the outer surface of this protective sleeve.

Wherein, this wrench body comprises a drive end and a connecting rod, and this drive end is positioned at an end of this wrench body, and this connecting rod is strip and the below that is linked to this drive end, and this grip part is connected in the below of this connecting rod.

Spanner with protective sleeve provided by the utility model, by above-mentioned technological means, advantage that can obtain and effect enhancement comprise at least:

1, protective sleeve of the present utility model be direct forming on wrench body, therefore can closely coat and cooperate fully the shape of any wrench body, even use spanner for a long time, the problem that does not also get loose prolongs life-span of protective sleeve.

2, the protuberance in the protection of the present utility model is formed in one on protective sleeve, so difficult drop-off, also can keep its outward appearance after use is long-time.

Below in conjunction with the drawings and specific embodiments the utility model is described in detail, but not as to qualification of the present utility model.

The specific embodiment

Being can detail knowledge technical characterictic of the present utility model and practical effect, and can implement according to the content of specification, further with as shown in the figure preferred embodiment, is described in detail as follows now:

First preferred embodiment of the present utility model please refer to shown in Figure 1, and the utility model is a kind of spanner with protective sleeve, comprises a wrench body 10A and a protective sleeve 20A, wherein:

In present embodiment, this wrench body 10A comprises a driving head 11A, a spanner 12A and a grip part, this driving head 11A and this spanner 12A are the subtend setting, and be divided into the two ends of this wrench body 10A, this driving head 11A is circular, and central authorities are hollow, internal perisporium in this driving head 11A is provided with ring-like ratchet 111A, this spanner 12A is concaved with the jaw 121A of a U-shaped, and this grip part is a prolate shape, and is linked to the central authorities of this driving head 11A and this spanner 12A;

This protective sleeve 20A is rigid plastic material, and inseparable shaping also is coated on this grip part, the surface of this protective sleeve 20A does not have the connection trace, and include a plurality of protuberance 21A, on the outer surface that is convexly set in this protective sleeve 20A that each protuberance 21A is formed in one, in present embodiment, each protuberance 21A is the cone of rhombus, and each protuberance 21A closely is arranged in front side and the rear side of this protective sleeve 20A, but does not limit shape and the arrangement mode of each protuberance 21A of the present utility model;
