The present invention relates to tools employed by truck operators, and, more particularly, to such tools used to release a fifth wheel pin of a tractor/trailer assembly. Specifically, the tool is a collapsible, telescopic pin puller. The tool has a grip end having a hammer and chisel, and a pin pull end having a hook and a protruded portion. The grip end and the pin pull end are connected by a telescopic elongate central portion which retracts into a handle which can be used as the handle of the hammer.

1. A tool comprising: a. a collapsible, elongate central portion comprising a plurality of elongate members, said plurality of elongate members capable of telescoping into one another; wherein the elongate central portion has at least two positions; a closed position wherein the elongate members are telescoped into one another such that a first elongate member is external to the remaining elongate members and forms a handle portion; and an open position wherein the elongate members are extended out from one another;b. a grip portion projecting from the first elongate member at a first end of the elongate central portion;c. an arm portion projecting from a second end of the elongate central portion, said arm portion comprising a hook portion and a protruded portion;d. a hammer head extending from a hammer end of the grip portion; ande. a locking mechanism whereby the tool can be locked in the closed position. 2. The tool of claim 1, wherein the grip portion is affixed to the handle portion. 3. The tool of claim 1, wherein the locking mechanism comprises a screw on a grip end of the elongate member most proximal to the arm portion, and a bolt in the handle portion whereby, in or when approaching the closed position, the screw is able to engage the bolt, locking the tool in the closed position. 4. The tool of claim of claim 3, further comprising a screw guide proximal to the bolt, and capable of guiding the screw into the bolt. 5. The tool of claim 4, wherein the screw guide is metal. 6. The tool of claim 3, further comprising a bolt guide proximal to the screw, and capable of guiding the bolt into the screw. 7. The tool of claim 6, wherein the bolt guide is metal. 8. The tool of claim 1, wherein the locking mechanism comprises a bolt on a grip end of the elongate member most proximal to the arm portion, and a screw in the handle portion or in the grip portion inside the handle portion, whereby, in or when approaching the closed position, the screw end is able to engage the bolt, locking the tool in the closed position. 9. The tool of claim 1, wherein the locking mechanism comprises a friction fit. 10. The tool of claim 1, wherein the locking mechanism comprises a pin on the arm portion, or on the elongate member most proximal to the arm portion, and a notch on the first elongate member, whereby the pin can be positioned within the notch or can engage the notch. 11. The tool of claim 10, whereby the pin is biased in a locking position by means of a spring located in the first elongate member and compressing when the tool approaches the closed position. 12. The tool of claim 1, further comprising a second locking mechanism whereby the tool can be locked in the open position. 13. The tool of claim 12, wherein the second locking mechanism comprises a friction fit. 14. The tool of claim 12, wherein the second locking mechanism comprises a tongue and groove assembly within each of the elongate members. 15. The tool of claim 1, further comprising a chisel extending from a chisel end of the grip portion, said chisel end being opposite the hammer end. 16. The tool of claim 1, further comprising a grip on said grip portion. 17. The tool of claim 16, wherein the grip is imbedded into said grip portion. 18. The tool of claim 16, wherein the grip is applied onto said grip portion. 19. The tool of claim 16, wherein the grip is a series of indentations in said grip portion. 20. The tool of claim 1, wherein the protruded portion has a magnetic end. 21. The tool of claim 20, wherein the magnetic end is proximal to, embedded into, or abutting from said protruded portion. 22. The tool of claim 1, further comprising a light on said arm portion. 23. The tool of claim 22, further comprising a light switch on said grip portion, said light switch capable of operating said light in either the open position or the closed position. 24. The tool of claim 22, further comprising a power supply within the grip portion, for powering said light. 25. The tool of claim 22, further comprising a power supply within the handle portion for powering said light. 26. The tool of claim 22, wherein the light is an LED. 27. The tool of claim 1, further comprising a shield projecting radially from the arm portion or the elongate member most proximal to the arm portion, such shield forming a seal or engaging with the first elongate member when the tool is in the closed position. 28. The tool of claim 1, further comprising a magnet inside the grip portion for exerting a magnetic force on at least one of the elongate members to bias the elongate central portion in the closed position.
