Title: Wrench having a light device

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a wrench, and more particularly to an adjustable wrench having a light device. 
     2. Description of the Prior Art 
     Typical wrenches comprise one or more batteries received in a handle, and a socket rotatably secured to the handle for receiving a light bulb or the like. U.S. Pat. No. 5,899,554 to Hsu discloses one of the typical wrenches. However, the light device includes a complicated configuration that may not be easily assembled and may not be easily repaired or fixed when the light device is out of order. 
     The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional adjustable wrenches. 
     SUMMARY OF THE INVENTION 
     The primary objective of the present invention is to provide a wrench having an easily attached light device. 
     In accordance with one aspect of the invention, there is provided a wrench comprising a handle including a chamber formed therein, a light device received in the chamber of the handle, and a cover pivotally secured to the handle for securing the light device in the handle. 
     The handle includes a latch opening formed therein, the cover includes a first end pivotally secured to the handle and includes a second end having a latch for engaging with the latch opening of the handle and for engaging with and for securing the light device in the handle. 
     The handle includes a wall having at least one opening formed therein, the light device includes a switch received in the at least one opening of the wall for being actuated by a user. 
     The handle includes a first end having an arm and a fixed jaw extended therefrom, a sliding jaw slidably received in the first end of the handle, and means for moving the sliding jaw toward and away from the fixed jaw. 
     The moving means includes a bolt rotatably received in the first end of the handle and secured to the sliding jaw, and a knob rotatably received in the first end of the handle and threaded on the bolt for moving the sliding jaw toward and away from the fixed jaw when the knob is rotated relative to the bolt. 
     The first end of the handle includes a curved recess formed therein for receiving the bolt, and includes an aperture formed therein for rotatably receiving the knob. 
     A cap is further provided and secured to the first end of the handle, and includes an orifice formed therein for rotatably receiving the knob and for retaining the knob in the aperture of the handle. The first end of the handle includes a depression formed therein for receiving the cap. 
     The sliding jaw includes a bar secured to the bolt and includes a beam slidably secured to the first end of the handle. The first end of the handle includes a rail formed therein, the beam of the sliding jaw includes a slot formed therein for slidably receiving the rail and for slidably securing the sliding jaw to the handle. 
     Further objectives and advantages of the present invention will become apparent from a careful reading of a detailed description provided hereinbelow, with appropriate reference to accompanying drawings.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Referring to the drawings, a wrench in accordance with the present invention is particularly an adjustable wrench and comprises a handle  10  including a fixed jaw  17  provided on one end thereof or extended from an arm  18  of the handle  10  and including an opening  31  formed in the one end thereof and defined by the fixed jaw  17 . An inclined surface  20  is formed in the root portion or in one end of the fixed jaw  17 . The one end of the handle  10  includes a curved recess  21  formed therein and communicating with the opening  31  thereof for rotatably and/or slidably receiving a bolt  12 ; and includes an aperture  22  formed therein and communicating with the curved recess  21  thereof for rotatably receiving a control ferrule or a knob  13  therein. The bolt  12  is threaded through the knob  13  and may be caused to move along the curved recess  21  of the handle  10  when the knob  13  is rotated relative to the handle  10 . The handle  10  includes one or more screw holes  23 ,  24  formed therein and includes a depression  19  formed therein and communicating with the curved recess  21  and the aperture  22  and the screw holes  23 ,  24  of the handle  10 . 
     The handle  10  further includes a longitudinal rail  25 , such as a dovetail, formed in the one end thereof. A sliding jaw  11  includes a bar  26  secured to one end of the bolt  12  and includes a beam  16  having a slot  27  formed therein, such as a dovetail slot  27  formed therein, for slidably receiving the rail  25  and for slidably securing the sliding jaw  11  onto the handle  10  and for allowing the bar  26  of the sliding jaw  11  to be moved toward and away from the fixed jaw  17 . The bar  26  of the sliding jaw  11  may be moved toward and away from the fixed jaw  17 , by moving the bolt  12  with the rotation of the knob  13 , in order to clamp and the drive the workpiece or the fastener between the fixed jaw  17  and the bar  26  of the sliding jaw  11 . A cap  14  is received in the depression  19  of the handle  10  and includes one or more holes  29 ,  30  formed therein for receiving the fasteners  40  which may secure the cap  14  to the handle  10 . The cap  14  includes an orifice  28  formed therein for rotatably receiving the knob  13  which is partially exposed or extended outward of the orifice  28  of the cap  14  such that the knob  13  may be rotated and actuated by the users. The orifice  28  of the cap  14  has a size arranged to rotatably retaining the knob  13  in the aperture  22  of the handle  10 . 
     As best shown in FIG. 1, the bar  26  of the sliding jaw  11  includes one end  33  slidably engaging with the arm  18  of the handle  10 ; and the beam  16  of the sliding jaw  11  has an inner surface  32  slidably engaged with the handle  10  such that the sliding jaw  11  may be stably and solidly secured to the handle  10 . 
     The handle  10  includes a chamber  15  formed therein and defined by a wall  34  for receiving a light device, such as a flashlight  37  therein, which may be easily and quickly engaged into the chamber  15  of the handle  10 . The wall  34  includes one or more openings  35  formed therein for receiving the head of the light device  37  and/or the switch  38  of the light device  37  etc. A cover  36  has one end pivotally secured to the handle  10  and has a latch  39  provided on the other end thereof for engaging with a latch opening  41  of the handle  10  and for openably securing the cover  36  to the handle  10  and for securing the light device  37  in the handle  10 . As shown in FIG. 2, the switch  38  of the light device  37  is exposed through the opening  35  of the wall  34  and may be easily operated by the user. In addition, the light device  37  may be easily and quickly changed or replaced with the other one when it is required to do so. 
     Accordingly, the wrench in accordance with the present invention includes an easily attachable light device that may be easily attached onto and disengaged from the handle of the wrench. 
     Although this invention has been described with a certain degree of particularity, it is to be understood that the present disclosure has been made by way of example only and that numerous changes in the detailed construction and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as hereinafter claimed.
