Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a tool having an extendable handle.

[0002]

[Prior art]

 As is well known, conventional screwdrivers and spanners have handles of fixed length.

[0003]

[Problems to be solved by the invention]

 However, since the handle cannot be extended, the screw or nut cannot be turned in a small area. Therefore, a main object of the present invention is to provide a tool having an extendable handle.

[0004]

[Means for Solving the Problems]

 The present invention for solving the above-mentioned problems employs the means described in claim 1. According to this means, there is at least one groove and a hole at one end of the handle, including the handle and the operating rod. The extension body has at least one locking body for locking in the groove of the handle, and a lock unit for fitting into the hole of the handle is also provided. Thus, the extension body can be tightened to the handle to extend the handle.

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. First, as shown in FIGS. 1 to 3, a tool having an extendable handle according to an embodiment of the present invention mainly includes an extension body 20. At one end, a protruding body 23 and a plurality of locking bodies 25 and 26 are provided. The projection 23 has a hole 24 for connecting the drive head 70 to form a short handle tool. The extension body 20 has a ratchet wheel mechanism installed inside, and a lock unit 21 as well as a button 22 as shown in FIG. 4 to control the ratchet wheel mechanism outside. You.

A hole 35 is provided inside the handle 30 for fitting the protruding body 23, and has at least one concave groove 32 and a fitting groove 33 at one end. Then, the extension body 20 is locked to the handle 30 by the locking members 25 and 26 of the extension body 20. Since there is a hole 34 at the same end 31 of the handle 30, when the lock unit 21 of the extension body 20 is fitted, the extension body 20 is tightened to the handle 30, that is, the length of the handle 30 is extended. The other end of the handle 30 is provided with a socket 40. One end of the operating rod 60 is fitted into the handle 30, but the length of the operating rod 60 that can be inserted into the handle 30 using the convex ring 61 as a stopper is limited. A hole 63 is provided at one end of the operating rod 60 for connecting the drive head 70. A link rod 50 is connected to the other end. Since the other end of the link rod 50 is inserted into the hole 24 of the protrusion 23, both the extension body 20 and the handle 30 can drive the operating rod 60.

Of course, the link rod 50 is not required, and the operating rod 60 may be directly mounted on the handle 30 and driven. The extension body 20 is attached to the handle 30 in order to extend the length of the handle 30.
