2. Description of the Related Art
A conventional tool for nail pulling and prying material on the surface includes a pry bar formed on an end thereof and a handle formed on another end thereof. However, the tool is usually formed as one piece and the distance between the pry bar and the handle cannot be adjusted so that it causes that the tool is just adapted for pulling nails whose size is limited to a particular range, and if nail whose size is over the range, the tool could not pull out the nail fully. Moreover, when a user operates the tool to pry something on a narrow place, it is difficult to find a fulcrum for supporting.
Therefore, the present invention is intended to obviate or at least alleviate the problems encountered in prior art.
It is therefore an object of the present invention to provide a multi-function tool that includes a pry bar and a foot hold and is adapted to be adjusted the distance between the pry bar and the foot hold for clamping materials with various sizes.
Accordingly, the present invention provides a multi-function tool includes a shank body, a pry bar slidably mounted on the shank body longitudinally, two clutches coupling the pry bar to the shank body and a foot hold rotatably installed to the bottom of the pry bar and adapted for receiving an end of the shank body. The shank body includes a first end, a second end inserted through the pry bar and a plurality of located grooves aligned thereon from the second end to the first end. The pry bar includes a first section for engaging with a selective one of the located grooves, a second section for prying and two second receptacles transversely formed therethrough for receiving two clutches respectively, with each of the clutches adapted for fixing the pry bar to the selective one located groove so that the pry bar can be adjusted to a desired location on the shank body. The foot hold is disposed onto the bottom of the pry bar, and the second end of the shank body is inserted through the first receptacle of pry bar and then is installed to the foot hold, with the foot hold being able to rotate relative to the shank body.
Other objectives, advantages, and features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

While the foot hold 40a is being rotated relative with the shank body 10a, the ball 14a, which is originally engaged with the one of the located portions 434a, is displaced and pushed to press the spring 15a by the inner wall of the compartment 431a. Therefore, the ball 14a is pushed into the aperture 122a of the shank body 10a and the spring 15a is pressed. Subsequently, the ball 14a contacts with the other one of the located portions 434a as the foot hold 40a is rotated to a desired position, and the ball 14a is pressed outwardly by the spring 15a again and slightly projects from the aperture 122a of the shank body 10 so that the foot hold 40a is fixed to the shank body 1Oa in this position via engagement of the ball 14a and the other one of the located portions 434a. In these drawings, the direction of axis of the second section 42a of the foot hold 40a is perpendicular to that of the second section 22a of the pry bar 20a.
Furthermore, the foot hold 40a can be rotated relative to the shank body 10a clockwise or counterclockwise, and the ball 14a of the shank body 10a is selectively engaged with the four located portions 434a so that the foot hold 40a can be rotated to four positions with respect to the shank body 10a. Except for the two positions that are discussed in the above, the foot hold 40a can be rotated to two positions. In one of the two positions, the direction of axis of the second section 42a of the foot hold 40a is parallel to that of the second section 22a of the pry bar 20a; however, the second section 42a is disengaged from the receiving portion 222a. In another one of the two positions, the direction of axis of the second section 42a of the foot hold 40a is perpendicular to that of the second section 22a of the pry bar 20a; however, the direction of axis of the second section 42a is opposite to that is shown in
