Abstract

The utility model discloses an adjustable hexagonal wrench, which is characterized in that it comprises an arm bar, a connecting seat and a hexagonal connecting ring. The rod is fixedly connected with the connecting seat, and each side of the hexagonal connecting ring is screwed with a long screw that extends radially. The inner end of the long screw is fixed with a clamping block, and the six clamping blocks form a regular hexagon. The outer end of the long screw rod is fixed with a turntable; the advantage is that when the hexagonal wrench tightens or loosens the nuts and screws, the six sides of the hexagonal nuts and screws are clamped by six clamping blocks to achieve twisting, and the clamping is stable, and because The clamping blocks are fixed on the long screw rod, so that the position of each clamping block can be adjusted, so that the hexagonal wrench can be used for screwing inner and outer hexagonal screws and nuts of different specifications, and has good versatility.

Description

An adjustable hex wrench

technical field

The utility model relates to a wrench for screwing screws and nuts, in particular to an adjustable hexagonal wrench.

Background technique

In the mechanical field, screws and nuts are the most conventional parts used to realize the interconnection of parts. The current screws and nuts are standard parts, and the main specifications are φ10mm, φ12mm, φ16mm, φ20mm, etc. And based on the needs of assembly and disassembly, it is usually necessary to use a wrench to tighten or loosen the screws and nuts. At present, the most widely used wrenches are adjustable tiger's mouth wrench and hexagonal wrench of fixed specifications. The side is twisted, and it can be seen that the clamping stability of the tiger's mouth wrench is far inferior to that of the hexagonal wrench. But because a kind of hexagonal wrench can only screw the screw of a kind of specification, nut, so the inner hexagonal wrench and the outer hexagonal wrench of various specifications are arranged on the market, its cost is higher, and versatility is bad.

Contents of the invention

The technical problem to be solved by the utility model is to provide an adjustable hexagonal wrench with stable clamping and good versatility.

The technical solution adopted by the utility model to solve the above technical problems is: an adjustable hexagonal wrench, including an arm, a connecting seat and a hexagonal connecting ring, the connecting seat is fixedly connected to one end of the arm, The hexagonal connecting ring is located below the connecting seat and is fixedly connected to the connecting seat through a plurality of connecting rods, and each side of the hexagonal connecting ring is screwed with a radially extending long screw rod , the inner end of the long screw is fixedly provided with a clamping block, the six clamping blocks form a regular hexagon, and the outer end of the long screw is fixedly provided with a turntable.

Further, the inner end of the long screw is provided with a polished rod section, the clamping block is sleeved on the polished rod section, the inner end of the long screw is screwed with a lock nut, through the The locking nut fixes the clamping block on the long screw rod; this structure enables the clamping block to be replaced according to the specifications of the screws and nuts that need to be tightened or loosened.

Further, the connecting rod is arc-shaped.

Compared with the prior art, the utility model has the advantage that when the hexagonal wrench tightens or loosens the nuts and screws, the six sides of the hexagonal nuts and screws are clamped by six clamping blocks to realize twisting, and the clamping is stable, and Since the clamping blocks are fixed on the long screw rod, the position of each clamping block can be adjusted, so that the hexagonal wrench can be used for screwing inner and outer hexagonal screws and nuts of different specifications, and has good versatility.
