2. A tool as claimed in claim 1 wherein the positioning device consists of a controller, a resilient member and a retaining member, with the plurality of detents and the first body section located at the controller, with the resilient and retaining members disposed in the cavity, with the controller inserted through the resilient member and coupled to the retaining member.

3. A tool adapted for prying comprising:

a handle including a pivotal end and a grip end, with the pivotal end having a through-hole;

a working device having first and second ends, with the first end of the working device pivotally connected to the pivotal end of the handle and including a positioned hole formed transversely and a cavity formed longitudinally and communicating with the positioned hole, with the positioned hole corresponding to the through-hole;

a positioning device disposed at the through-hole, the positioned hole and the cavity and moveable between a fixing position and an adjusting position;

wherein while the positioning device is in the fixing position, the handle is fixed in position with respect to the working device; wherein while the positioning device is in the adjusting position, the handle is able to pivot with respect to the working device; and

a coupled portion defined at the pivotal end and inserted into a slot defined at the working device, with the slot sandwiched between the positioned hole and the cavity and extending from the first end to the second end of the working device.

4. A tool as claimed in claim 3 further comprising a hammering portion extending from a distal portion of the pivotal end and treated as a hammer.

5. A tool as claimed in claim 4 further comprising two limited portions formed on two sides of the coupled portion and proximal to the hammering portion.

6. A tool adapted for prying comprising:

a handle including a pivotal end and a grip end, with the pivotal end having a through-hole;

a working device having first and second ends, with the first end of the working device pivotally connected to the pivotal end of the handle and including a positioned hole formed transversely and a cavity formed longitudinally and communicating with the positioned hole, with the positioned hole corresponding to the through-hole;

a positioning device disposed at the through-hole, the positioned hole and the cavity and moveable between a fixing position and an adjusting position;

wherein while the positioning device is in the fixing position, the handle is fixed in position with respect to the working device; wherein while the positioning device is in the adjusting position, the handle is able to pivot with respect to the working device; and

a prying device attached to the second end of the working device for extracting an element to be pried.

7. A tool as claimed in claim 6 further comprising a pressed portion formed on the outer periphery of the working device between the first and second ends.

8. A tool as claimed in claim 6 wherein the prying device comprises a shaft, two pry elements moveably disposed at two ends of the shaft and two positioning units, with each positioning unit adapted to removably fix the related pry element to the related end of the shaft.

9. A tool as claimed in claim 8 further comprising a plurality of positioning sections respectively provided on the outer periphery of two ends of the shaft in a transverse line arrangement and first and second connected holes formed on each pry element and communicating with each other, with the shaft inserted into the first connected hole, with the plurality of positioning units disposed in the second connected holes and selectively engaged with the selected one positioning section.

10. A tool as claimed in claim 9 wherein each positioning units consists of a control member, a resilient member and a detent, with the control member inserted into the second connected hole, with the detent moveable between the selected one positioning section and a recess formed on the control member and selectively engaged with the selected one positioning section or the recess.

11. A tool as claimed in claim 10 wherein the control member has a head and a body, with the recess and an abutting section formed on the body; and wherein the detent is restricted between the recess and the abutting section and positioned at the second connected hole.

12. A tool as claimed in claim 11 wherein the second hole of each pry element has first and second sections, and wherein a diameter of the first section is larger than that of the second section.

13. A tool as claimed in claim 12 wherein the resilient member is mounted on the body and restricted at the first section of the second connected hole.

14. A tool as claimed in claim 2 , with the through-hole being hexagonal, and with the first body section having a hexagonal cross-section to correspond to and engage with the trough-hole.

15. A tool as claimed in claim 2 wherein the controller further includes a cap, a second body section and a joint, with the cap exposed from the positioned hole and being opposite to the joint, with the first body section adjacent to the cap, with the second body section adjacent to the joint and inserted through the resilient member in the cavity, and with the joint attached to the retaining member.

16. A tool as claimed in claim 8 further comprising a coupled hole transversely formed at the second end and communicating with the slot; wherein the coupled hole is spaced from the positioned hole and inserted by the shaft of the prying device.
