Abstract

A wrench or spanner includes two jaws 11 extending from an end of a handle 10 with a hole 20 defined in at least one of the jaws. The hole 20 communicates with a clamping surface 122 of the jaw and a magnet 30 is received in the hole 20. The magnet 30 attracts the object that is clamped by the wrench while in use. A spring (32, fig. 6) may be provided to bias the magnet 30, and a flange 21 may extend inwardly from the opening defined by the hole 20 in order to retain the magnet 30 in the hole 20.

Description

FIELD OF TlIE INVENTION
The present invention relates to a wrench that has at least one magnet embedded in one of the two jaws so as to attract an object during use.
GROUND OF TIDE INVIDIYTI()N A conventional wrench generally includes two jaws and a handle.
An object can be clamped between the two jaws and is rotated to be loosened or tightened. The opening of the two jaws is slightly larger than the object to be loosened or tightened so that it is easily to mount the jaws to the object. In order to clamp the object, the user has to carefully operate the wrench to make sure that the object is located in the opening. This is difficult to maintain the object in the opening especially when the object is loosened. Besides, the object to be loosened could be hot in temperature or contaminated by toxic material so that the user cannot touch. In this situation, the conventional wrench is more difficult to maintain the object in the opening.
The present invention intends to provide a wrench that has a magnet embedded in one of the two jaws so as to keep the object in the opening between the two jaws.
SUMMARY OF THE INVENTION
In accordance with one aspect of the present invention, there is provided a wrench which comprises two jaws on one end of a handle of the wrench and a hole is defined in one of the jaws. The hole communicates with a clamping surface of the jaw having the hole and a magnet is received in the hole.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.
BRIE1F DESCRIPTION OF TlIE DRAWINGS
Fig. 1 is an exploded view to show a magnet and the wrench of the present invention; Fig. 2 is a cross sectional view to show the wrench of the present invention; Fig. 3 shows that an object is clamped by the two jaws of the present invention; Fig. 4 is a perspective view to show the wrench of the present invention; Fig. 5 is a cross sectional view to show that both of the two jaws have a magnet, and Fig. 6 shows a spring biased between the magnet and an end piece.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to Figs. 1 to 4, the wrench of the present invention comprises two jaws 11 extending from an end of a handle 10 of the wrench and a hole 20 is defined in one of the jaws 11. The hole 20 communicates with a clamping surface 122 of the jaw 11 having the hole 20 and the hole defines an opening which communicates with the clamping surface 122.
A flange 21 extends inward from the opening.
A magnet 30 is received in the hole 20 and stopped by the flange 21 so that the magnet 30 is retained in the hole 20. An end piece 31 is received in the hole 20 and located in opposite to the clamping surface of the jaw 11. The end piece 31 is in flush with an outer surface of the jaw l l and is polished such that the outer surface of the jaw 11 is smooth. An object such as a nut 13 is received in the space 12 between the two jaws 11 and can be attracted by the magnet 13.
Because the nut 13 generally applies a force at point "A" on the clamping surface 122 and the clamping surface 121 on the other jaw 11 so that the hole 20 is drilled away from the point "A" may reduce the possibility of weakening the structural strength of the jaw 11.
Fig. 5 shows that both of the two jaws 11 have a magnet 30 received therein so as to position the nut 13 firmly. Fig. 6 shows a spring 32 is biased between the magnet 30 and the end piece 31. The magnet 30 is allowed to be slightly protruded into the space 12 between the two jaws 11 so that the object to be clamped contacts the magnet 30 for sure.
While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
