The utility model is characterized in that a set of connecting sleeves and connecting rods are designed, and the connecting sleeves and the connecting rods are matched with the specification of the socket wrench and has different sizes. The outside of the connecting sleeves is an outside hexagon which is matched with the socket wrench, and the two ends are respectively an inner hexagonal hole and an inner square hole to fix and disassemble screws with different specifications, reaming holes and various connecting components, and the size of the wrench opening is between 2.5 mm and 32 mm. The utility model has the advantages of simple structure, convenient operation, complete function and high work efficiency.

Description

Accessory of box spanner

The utility model relates to a kind of hand tools.

The ordinary cartridge spanner is only applicable to the fastening connection piece of fastening or dismounting band outer-hexagonal and tapping, the fraising function of the outer square head of band, and the wrench opening size in its outer six sides and outer four directions is only between 8-32mm.Then inapplicable for the wrench opening size less than the outer-hexagonal of 8mm and outer four directions, more be not suitable for hexagonal, flat recess, cross recessed fastening connection piece in the band, make and assemble and maintenance personal's inconvenience of working, also influence its operating efficiency.

The purpose of this utility model is, a kind of simple in structure, suitable, hand tools annex that can enlarge the box spanner function is provided.Make box spanner give full play to its effect,, improve its operating efficiency with workman convenient for assembly and maintenance personal.

Technical solution of the present utility model is, designs one group and is complementary with the box spanner specification, and the different function expansion of size connects cover and extension bar.The outside that connects cover is and interior six sides of the sleeve of spanner outer hexahedron mutually, hexagonal hole and internal square hole in two ends are respectively; Extension bar is outer hexahedron, and it is complementary with the interior hexagonal hole that connects cover; Needs with functions such as the tapping of the fastening of the fastening connection piece that adapts to inside and outside hexagonal, manifold, crosshead and dismounting and band square head, fraisings.

Now the present invention is described in further detail in conjunction with the accompanying drawings and embodiments.

Fig. 1 is the constitutional diagram of tapping embodiment of the present invention.

Fig. 2 is the constitutional diagram of fraising embodiment of the present invention.

Fig. 3 is the constitutional diagram of embodiment of the fastening or dismounting of crosshead of the present invention.

Fig. 4 is the constitutional diagram of the embodiment of the fastening of manifold connector of the present invention or dismounting.

Fig. 5 is the constitutional diagram of the embodiment of the fastening of hexagon socket head connector of the present invention or dismounting.

Fig. 6 is the A-A profile of Fig. 1.

Fig. 7 is the B-B profile of Fig. 1.

In Fig. 1 embodiment, an end that connects hexagonal hole in cover 2 bands inserts in the interior hexagonal hole of sleeve 1 of box spanner, and the screw tap 4 of the outer square head of band inserts to connect and overlaps in 2 the internal square hole, can realize tapping.

In Fig. 2 embodiment,, can realize fraising with being with the reamer 5 of outer square head to insert in the internal square hole that connects cover 2.

In Fig. 3 embodiment, will the outer four directions of band or cross (plum blossom) screwdrivers 6 of outer six square toes insert in the interior four directions or interior hexagonal hole that connects cover 2, can realize connector function fastening or dismounting band cross (plum blossom) head.

In Fig. 4 embodiment, the outer manifold screwdrivers 7 cubic or outer six square toes of band are inserted in the interior four directions or interior hexagonal hole that connects cover 2, can realize connector function fastening or the dismounting manifold.

In Fig. 5 embodiment, an end that connects the band internal square hole of cover 2 is inserted in the interior hexagonal hole of sleeve 1, extension bar 3 inserts in the interior hexagonal hole that connects cover 2, can realize the connector function of six sides in fastening or the dismounting band.

In Fig. 6, meet cover 2 outer six square chi cun A in 8～32mm scope, and be complementary with sleeve 1.The size C that connects the interior hexagonal hole of cover 2 is in 2.5～6.3mm scope, to realize the fastening and disassembling function of the interior six sides fastening connector of wrench opening size in 2.5～32mm scope.

In Fig. 7, meeting cover 2 internal square hole size B is in 2.5～6.3mm scope, with the 8-32mm function of box spanner itself constitute the tapping of the different size of wrench opening size in 2.5～32mm scope and fraising and a word, crosshead fastening connector fastening with dismantle.Enlarged the function of former box spanner.

Sleeve 1 itself has the fastening or outer hexagon opening of dismounting of 8～32mm, mixes the allen wrench opening of the 2.5～6.3mm that connects cover 2, promptly realizes the fastening and disassembling function of the outer-hexagonal connector in 2.5～32mm scope.

The utility model has been expanded wrench opening and has been of a size of inside and outside six sides of 2.5～6.3mm scope and fastening and dismounting and the tapping and the fraising function of the various connectors in outer four directions, bring into play the effect of box spanner effectively, improve assembler and maintenance personal's operating efficiency.
