Abstract

A palm type spanner comprises a driving head having a receiving portion for receiving a driving tool; and a handle body being an integral plate-like structure; one end of the handle body being formed with an opening portion; the driving head being pivotally installed to the handle body; thereby the driving head being rotatable along the pivotal shaft; and the handle body having a hollowed groove which has a size capable of receiving the driving head.

Claims

1. A palm type spanner comprising:

a driving head having a receiving portion for receiving a driving tool; and

a handle body being an integral plate-like structure;

one end of the handle body being formed with an opening portion;

the driving head being pivotally installed to the handle body;

thereby the driving head being rotatable along a pivotal shaft installed at the opening portion of the handle body;

the handle body having a hollowed groove which has a size capable of receiving the driving head;

wherein two lateral sides of the driving head aside the receiving portion being formed with retaining holes for retaining positioning elements.

2. The palm type spanner as claimed in claim 1, wherein a driving tool is installed to the driving head by using positioning elements to pass through the retaining holes of the driving head so as to be further inserted insert into the recesses the driving tools.

3. A palm type spanner comprising:

a driving head having a receiving portion for receiving a driving tool; and

the receiving portion is a hole in the driving head;

a handle body being an integral plate-like structure;

one end of the handle body being formed with an opening portion;

the driving head being pivotally installed to the handle body;

thereby the driving head being rotatable along a pivotal shaft;

the handle body having a hollowed groove which has a size capable of receiving the driving head; and

a driving tool installed to the driving head for driving an object to be driven by the palm type spanner; and

wherein the driving tool is assembled into the receiving portion of the driving head;

two sides of the driving tool have respective recesses corresponding to the retaining holes of the receiving portion;

when the driving tool is assembled to the driving head, the positioning element passes through the retaining holes to insert into the recess so as to fix the driving tool.
