Description

Solid wrench with adjustable clamping opening size

Technical Field

The utility model relates to a manual spanner instrument technical field especially relates to a press from both sides mouthful adjustable solid wrench of size.

Background

One or two ends of the solid wrench are provided with openings or trepanning for screwing bolts, screws, nuts and other screw threads to tightly hold the bolts or the nuts. One solid wrench can only screw or unscrew one or two specifications of bolts and nuts. The size of the clamping opening of the existing solid wrench is not adjustable, two different unit systems of metric system and English system exist, and a repairman needs to prepare dozens of solid wrenches to comprehensively deal with screws and nuts with different sizes. Too many repair tools have heavy weight and large volume, are inconvenient to carry, and have high cost for purchasing dozens of solid wrenches.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that the technique that exists is not enough to the aforesaid, provides a press from both sides a mouthful adjustable solid wrench of size, adopts adjustable structural style about the inlay card piece to adjust and press from both sides a mouthful size.

In order to solve the technical problem, the utility model discloses the technical scheme who adopts is: a solid wrench with an adjustable clamping opening comprises a body, an adjusting roller and a clamping and embedding piece; the body comprises a head and a handle; the head of the body is round; the head part is provided with a regular hexagon through hole; the handle part is provided with a through rectangular groove at the position close to the head part; the adjusting roller is a hollow cylinder and is internally provided with internal threads; the clamping and embedding piece comprises a clamping head and a rod part; the chuck is embedded in the body; the rod part is provided with an external thread and is accommodated in an inner containing hole penetrating through the rectangular groove; the adjusting roller is positioned in the rectangular groove and is in threaded fit with the rod part.

Further optimizing the technical scheme, the axis of the regular hexagon through hole passing through the two vertexes is positioned in the long axis direction of the handle part; the shape of the upper end of the clamping head is matched with the shape of the regular hexagon through hole. .

Further optimize this technical scheme, the surface of regulating roller has skid-proof decorative pattern.

Further optimize this technical scheme, the handle portion overcoat is skid-proof plastics or rubber.

Compared with the prior art, the utility model has the advantages of it is following: 1. the adjusting roller is matched with the clamping and embedding piece to adjust the lifting of the clamping and embedding piece, and the structure is favorable for ensuring that the size of the clamping opening is adjustable; 2. the through hole at the head of the body is in a regular hexagon shape, and the structure is favorable for ensuring that the bolt and the nut are well matched with the existing standard bolt and nut; 3. the outer surface of the adjusting roller is provided with anti-slip patterns, and the structure is favorable for ensuring that the clamping opening is convenient, quick and non-slip when the size of the clamping opening is adjusted.

In the figure: 1. a body; 11. a regular hexagonal through hole; 12. a rectangular groove; 13. an internal bore; 2. a card insert; 21. clamping a head; 22. a rod portion; 3. and adjusting the roller.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

The specific implementation mode is as follows: referring to fig. 1-4, the adjustable jaw solid wrench of the present invention comprises a body 1, an adjusting roller 3 and an insert 2; the body 1 comprises a head and a handle; the head of the body 1 is round; the head part is provided with a regular hexagon through hole 11; the handle part is provided with a through rectangular groove 12 at the position close to the head part; the adjusting roller 3 is a hollow cylinder and is internally provided with internal threads; the card insert 2 comprises a card head 21 and a rod part 22; the chuck 21 is embedded in the body 1; the rod part 22 is provided with an external thread and is accommodated in an inner containing hole 13 penetrating through the rectangular groove 12; the adjusting roller 3 is positioned in the rectangular groove 12 and is in threaded fit with the rod part 22.

The axis of the regular hexagonal through hole 11 passing through two vertexes is located in the long axis direction of the shank; the shape of the upper end of the clamping head 21 is matched with that of the regular hexagon through hole 11. The outer surface of the regulating roller 3 is preferably provided with a slip-resistant pattern. The handle is preferably coated with a non-slip plastic or rubber.

When in use, in the first step, a bolt and a nut to be screwed or unscrewed are firstly tried to be sleeved into the regular hexagon through hole 11. And step two, if the size of the bayonet is too small, the adjusting roller 3 is rotated to enlarge the bayonet. And step three, after the bolt or the nut is sleeved into the regular hexagon through hole 11, the adjusting roller 3 is rotated until the bolt or the nut is clamped. And step four, starting to screw or unscrew the bolt and the nut.

It is to be understood that the above-described embodiments of the present invention are merely illustrative of or explaining the principles of the invention and are not to be construed as limiting the invention.
