Description

Combined wrench

A kind of combination wrench belongs to the hardware ﹠ tools class.

In plant produced, repairing, in the family daily life, all be unable to do without the five metals small tool, spanner also is one of them, though the instrument of past simple function is easy to use, but in the time need using the instrument of the multiple function of plurality of specifications simultaneously, when particularly going out, it is pretty troublesome really to carry numerous instruments, therefore there were several combination tools to appear on the market in recent years, it has brought convenience for people's working and learning, but a kind of combination tool that is specifically designed to the inside and outside die nut of spinning plurality of specifications also still belongs to shortcoming.

The purpose of this utility model just is to increase a kind of new varieties, i.e. combination wrench for the combination tool series products again.

Accompanying drawing 1 has proposed structural representation of the present utility model.

Can find out that from accompanying drawing 1 spanner of combination wrench (7) front end has a hexagon ring, interchangeable turret head (3) is inserted in the hexagon ring. Because turret head (3) has the preprocessing hole of two position symmetries, trip bolt (8) can be sold into this hole it is located. Spanner (7) is spirally connected with trigger piece (4), trigger piece is cannulated sleeve, built-in a plurality of turret head (3), can be interior hexagonal or outer-hexagonal, its two ends sizableness is in two specifications, comprise S=3,4,5,6,8,10,12,14 etc., trigger piece (4) tail end is the bonnet (2) that is threaded. The combinations thereof spanner can be used as the dismounting of soket head cap screw or outer-hexagonal nut.

As on spanner (7), adorning mobile the pulling (6) of a feather joint square with it, the medial surface of it and turret head (3) is parallel to each other, can be used as adjustable wrench uses, move to pull on (6) and have annular groove, the dog screw (1) that is spirally connected with nut sleeve (5) is housed in the groove, and nut sleeve (5) is spirally connected with trigger piece (4), unclamp dog screw (1), by turn to nut sleeve (5), can promote movable plate (6) displacement, regulate the distance with turret head (3) on request, screwed in place screw (1) promptly can be used to when adjustable wrench dismounting screw then.

The utlity model has plurality of specifications, can realize spinning by the transposing turret head to interior (or outer) hexagonal of different specification size, also can be used as adjustable wrench uses, this tool construction is simple, it is convenient to assemble, easy to use, to be convenient to go out to carry, it has increased new varieties for the combination tool product.

Claims (3)
