Description

Multi-directional wrench

Technical Field

The utility model relates to the field of manual tools, in particular to a multidirectional wrench.

Background

A wrench is a common installation and removal tool. Hand tools for turning bolts, screws, nuts and other threaded fasteners for tightening openings or trepanning of bolts or nuts using the principle of leverage. The wrench is used for fastening or disassembling bolts on machine tools, vehicles, mechanical equipment and the like, and manually applies torque by matching the threaded holes of a bolt nut, thereby fastening or loosening the bolts.

The current spanner to the external angle bolt is of a great variety, including solid wrench, monkey wrench, hook type spanner, box spanner and box spanner, solid wrench, monkey wrench and hook type spanner only need the edgewise clamp down the bolt, but because keep silent the angle problem, can appear rotatable angle undersize and can't find suitable angle even and clamp down the phenomenon of bolt when rotating narrow operating space's bolt, and box spanner's internal orifice is provided with a plurality of angles, but need entangle the bolt from the top, when rotating low operating space's bolt, can appear the phenomenon that the spanner head can't stretch into the bolt top entangle the bolt because of the altitude problem.

SUMMERY OF THE UTILITY MODEL

Aiming at the existing defects, the multi-direction wrench is designed to operate in a narrow and low operation space. The technical scheme of the utility model is as follows:

the utility model provides a multidirectional spanner, includes the spanner head of the different bolt of one or more adaptation or nut external diameter and supplies to hold the wrench handle of holding, spanner head and wrench handle fixed connection, and the semi-circular is seted up to the spanner head, and the inside fixed tooth that is provided with a plurality of outer edges and matches with bolt or nut of keeping silent.

Furthermore, the end parts of the fixed teeth are smooth convex surfaces, and the fixed teeth are connected through the smooth concave surfaces to form the interior of the wavy jaw.

Further, the number of the fixed teeth is 9, and the distance between the fixed teeth is 20 degrees.

Further, the number of the fixed teeth is 6, and the distance between the fixed teeth and the fixed teeth is 30 degrees.

Further, the fixed teeth are 12 in number and the distance is 15 degrees.

Furthermore, the cross section of the wrench handle is a round corner rectangle.

Furthermore, the wrench head and the wrench handle are made of stainless steel.

Furthermore, the surfaces of the wrench head and the wrench handle are plated with chromium.

Compared with the prior art, the utility model has the beneficial effects that:

1. the semicircular jaw can clamp a bolt or a nut from the side surface, does not need to be sleeved from the upper part, and is suitable for operation in a low space.

2. A plurality of fixed teeth are arranged in the semicircular jaw, so that bolts or nuts can be clamped at multiple angles, and the semicircular jaw is suitable for operation in a narrow space.

3. The inboard splint and the outside splint of this patent can be dismantled, and further increase is to the application scope of sole model, increases the stability of centre gripping.

4. The wavy jaws may more quickly and smoothly position and snap the bolt into the jaws.

5. The rectangular spanner handle cross-section of fillet is more fit for hand and holds.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The first embodiment is as follows:

referring to fig. 1, 2, 3 and 4, the present invention provides a multi-way wrench, which includes 2 wrench heads 1 adapted to different bolt 5 outer diameters and a wrench handle 2 for being held by a hand, wherein the wrench head 1 is fixedly connected to the wrench handle 2, the wrench head 1 is provided with a semicircular jaw 3, and 9 fixed teeth 4 are arranged inside the jaw 3 and are matched with the outer edge angle of the bolt 5 and have a distance of 20 degrees. The semicircular jaw provided with 9 fixed teeth can clamp a bolt or a nut from the side at multiple angles, does not need to be sleeved from the upper part, and is suitable for operation in a low and/or narrow space. The end parts of the fixed teeth 4 are smooth convex surfaces, the fixed teeth 4 are connected through smooth concave surfaces to form the interior of the wavy jaw 3, and the position of the bolt 5 can be quickly and smoothly positioned and clamped into the jaw 3. The cross-section of the wrench handle 2 is a round rectangle, the wrench head 1 and the wrench handle 2 are made of stainless steel, and the surfaces of the wrench head 1 and the wrench handle 2 are plated with chromium to prevent corrosion.

Example two:

referring to fig. 5, the difference between the second embodiment and the first embodiment is that the number of the fixed teeth 4(1) is 6, the distance between the fixed teeth is 30 degrees, and the other technical solutions are the same.

Example three:

referring to fig. 6, a difference between the third embodiment and the first embodiment is that the number of the fixed teeth 4(2) is 12, the distance between the fixed teeth is 15 degrees, and other technical solutions are the same.
