Abstract

The utility model relates to a multipurpose spanner, which mainly comprises a handle and a spanner. The utility model is characterized in that the spanner is provided with two spanners, namely, a socket spanner and an open-jawed spanner which are respectively arranged at both sides of the handle, the socket spanner is a closed ring, a spanner hole is arranged in the closed ring, and is composed of an upper bayonet and a V-shaped lower bayonet, the upper bayonet is at the outermost end, and is a hexagonal bayonet with a lower open-ended angle, a plurality of pairs of symmetrical slots A are arranged at both sides of the V-shaped lower bayonet, from the top to the bottom, the distance between each pair of slot is reduced gradually, and is respectively equal to the two width-across corners of hexagonal nuts with different side length; the open-jawed spanner is a reversed V-shaped opening, a plurality of pairs symmetrical slots B are arranged at both inner sides of the opening, from the top to the bottom, the distance between each pair of slot is increased gradually, and is respectively equal to the two width-across corners of the hexagonal nuts with different side length. The utility model is suitable to assemble and disassemble the hexagonal nut, and has the advantages of reasonable and simple structure, convenient operation and a tool for multipurpose.

Description

Combination wrench

Technical field

The utility model belongs to a kind of machine tool, and concrete is a kind of spanner that is used to load and unload hexagonal (hexagon)nut, particularly can be used for the back-up wrench of multiple different size hexagonal (hexagon)nut.

Background technology

Mechanical wrench is a kind of instrument commonly used, and now the spanner that uses is a kind of is movable, can before use the bore of spanner be regulated, and makes it to be suitable for the nut that will load and unload, and then uses; Another kind is a back-up wrench, and a spanner can only be applicable to the nut of two kinds of different sizes; Also having a kind of back-up wrench to go for the nut of several different sizes, is on the head of spanner the hole of the nut shape of several fixedly bores to be set, but has only seldom several, can only be enclosed within on the nut and use.In a word, existing manual wrench, still fixing no matter be movable, use not easily, can not be applicable to multiple different nut quickly and easily.Therefore, need to propose hand-held spanner a kind of simple in structure, easy to use, during use, need not regulate temporarily, just can be directly used in the nut of multiple different size, no matter and be enclosed within on the nut or clamp nut from the side and can both use.

The utility model content

The purpose of this utility model is in order to address the above problem, to propose a kind of combination wrench, and the many usefulness of this spanner one tool can be applicable to the nut of multiple different size, and convenient to use, simple in structure.

The purpose of this utility model solves by the following technical programs: combination wrench, mainly comprise handle, spanner, it is characterized in that: described spanner is two: cover spanner and open-end wrench, be separately positioned on the two ends of handle, the cover spanner is a closed-loop shaped, the inside is provided with pulls the hole, this is pulled the hole and is made of bayonet socket under upper latch notch and the V font, upper latch notch is in outermost end, can block hexagonal (hexagon)nut, be the hexagon bayonet socket that a following angle is an opening, the both sides of bayonet socket are provided with several draw-in groove A to symmetry under the described V font, the distance of every pair of draw-in groove is dwindled gradually from top to bottom, and two diagonal distance of different with the length of side respectively hexagon nuts equate; Described open-end wrench is an inverted v-shaped opening, and the inboard both sides of opening are provided with several draw-in groove B to symmetry, and the distance of every pair of draw-in groove increases gradually from top to bottom, and two diagonal distance of different with the length of side respectively hexagon nuts equate.

The utility model is owing to be provided with cover spanner and open-end wrench, and in spanner, be provided with many to draw-in groove apart from what do not wait, can make things convenient for the hexagonal (hexagon)nut that blocks different size securely, not only can above nut, put use, can also clamp nut from the side uses, very convenient, and be applicable to the nut of multiple different size.The utlity model has simple and reasonablely, make easily, with low cost, convenient to use, particularly can be applicable to the advantage of multiple nut.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation of hexagonal (hexagon)nut.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further described: embodiment: referring to accompanying drawing, combination wrench, mainly comprise handle, spanner, described spanner is two: overlap spanner 2 and open-end wrench 3, be separately positioned on the two ends of handle 1, the cover spanner is a closed-loop shaped, the inside is provided with and pulls the hole, and this is pulled the hole and is made of bayonet socket 2.2 under upper latch notch 2.1 and the V font, and upper latch notch is in outermost end, can block hexagonal (hexagon)nut, be the following angle hexagon bayonet socket that is opening 2.3; The both sides of bayonet socket are provided with several draw-in groove A 2.4 to symmetry under the described V font, and the distance of every pair of draw-in groove is dwindled gradually from top to bottom, and two diagonal angles, 4 distances of different with the length of side respectively hexagon nuts equate; Described open-end wrench is an inverted v-shaped opening, and the inboard both sides of opening are provided with several draw-in groove B 3.1 to symmetry, and the distance of every pair of draw-in groove increases gradually from top to bottom, and two diagonal angles, 4 distances of different with the length of side respectively hexagon nuts equate.The utility model tool using steel is done, and can make the series of products of different size.
