Clamp inside and outside, and finally loosen or tighten the bolts.

Description

An adjustable snap wrench

technical field

The utility model relates to a hardware tool, in particular to an adjustable buckle wrench.

Background technique

There are two major problems in the existing wrenches: 1) Various models and specifications, the scope of use of ordinary wrenches is limited; 2) Countersunk head bolts installed in special positions (deep or narrow positions) are very inconvenient to use; 3) For some special occasions (susceptible to corrosion, countersunk head bolts are prone to deformation), ordinary wrenches cannot be used at all.

Contents of the invention

The technical problem to be solved by the utility model is to provide an adjustable buckle wrench, which can be applied to countersunk head bolts of different types or special conditions, and is convenient for loosening or tightening bolts installed in deeper or narrower .

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:

An adjustable buckle wrench, comprising an inner sleeve and an outer sleeve, the outer surface of the lower part of the inner sleeve is provided with a threaded section, the bottom of the inner sleeve is uniformly surrounded by a plurality of elastic metal sheets, and the plurality of elastic metal sheets form an outwardly expanding Trumpet-shaped structure; the jacket includes a tube body, the upper part of the tube body is a round tube with internal threads, and the lower part is an expansion tube adapted to the horn-shaped structure composed of multiple elastic metal sheets.

Both the inner sleeve and the upper end of the outer sleeve are provided with handles.

The inner surface of the elastic metal sheet is provided with anti-slip protrusions.

The lower part of the inner sleeve is provided with a cavity, and a plurality of round rods are arranged in the cavity, and the magnetic properties of the round rods are opposite to those at the bottom of the cavity.

The elastic metal sheets are provided with magnetic substances, and the magnetic substances make the elastic metal sheets repel each other.

The utility model is an adjustable buckle wrench. By arranging an inner sleeve and an outer sleeve, an elastic metal sheet is arranged at the lower end of the inner sleeve, and a round rod capable of sliding in a short distance is arranged in the inner sleeve, so as to realize the internal and external clamping of countersunk head bolts. Tighten, and finally loosen or tighten the bolts.

detailed description

As shown in Figure 1-3, an adjustable buckle wrench includes an inner sleeve 1 and an outer sleeve 2, the outer surface of the lower part of the inner sleeve 1 is provided with a threaded section 3, and the bottom of the inner sleeve 1 is evenly distributed with six elastic metal Sheet 4, six elastic metal sheets 4 form a horn-like structure that expands outward; the outer casing 2 includes a tube body 5, the upper part of which is a circular tube with internal threads, and the lower part is formed with six elastic metal sheets 4 The flared structure is compatible with the expansion tube.

The upper ends of the inner sleeve 1 and the outer sleeve 2 are provided with handles 6 . With this structure, the handle on the outer sleeve is convenient for positioning and locking, and the handle on the inner sleeve is convenient for providing torque to the bolts to loosen or tighten the bolts.

The inner surface of the elastic metal sheet 4 is provided with anti-slip protrusions 7 . With this structure, the friction in contact with the bolt is increased to prevent slipping.

The lower part of the inner sleeve 1 is provided with a cavity, and a plurality of round rods 8 are arranged in the cavity, and the magnetic properties of the round rods are opposite to those at the bottom of the cavity. With this structure, during operation, part of the cylindrical rod can be inserted into the groove of the countersunk bolt, and the bolt can be loosened or tightened through internal and external clamping.

The elastic metal sheet 4 is provided with a magnetic substance, and the magnetic substance makes the elastic metal sheet 4 repel each other. Therefore, the elastic metal sheet 4 is always kept in an open state in the non-working state, preventing the elastic metal sheet from losing the elasticity of opening after being squeezed for a long time and causing inconvenience to the operation.

During work, first align the horn-shaped structure formed by the six elastic metal sheets 4 of the device with the countersunk bolt, so that the round rod 8 is inserted into the groove of the countersunk bolt, and the handle 6 on the outer cover 2 is rotated to make the The expansion tube at the lower part of the tube body 5 moves downwards, and the bolts are loosened or tightened through internal and external clamping.
