Each of the tool attachments 25 includes a tool mating end 29 releasably attachable to the head mating end 27. Each of the plurality of tool attachments 25 may include a tool portion including a different type of tool. Therefore, different tool attachments 25 may be connected to the head 14 to form different tools.

The handle 12 of the present invention may be made by a metal, fiberglass, wood, plastic or the like. A rubber sleeve may be secured over the handle 12 to provide additional comfort. The head 14 and tool attachments 25 may be made of a metal or other solid material. The head 14 may interface the tool attachments 25 to form a metal to metal even-forced distribution. The design of the present invention is capable of absorbing shock and to distribute force evenly. The head 14 and the handle 12 may be integral. However, in certain embodiments, the head 14 and the handle 12 may be releasably attachable. For example, looking at FIG. 17 the handle 12 may include a post 84 that fits within a slot 88 formed through the head 14 on both designs.

As illustrated in FIG. 1, the first end and the second end of the head 14 may each include a head mating end 27. In certain embodiments, the head mating end 27 includes a concave outer portion 172. The concave outer portion 172 forms an upper lip and a lower lip. Formed in between the upper lip and the lower lip are outer male slide tabs 210 having a convex shape. A concave mid slot 174 is formed at a center of the concave outer portion 172 in between the outer male slide tabs 210. A t-slot 176 is formed through the lower lip and a pin slot 178 is formed through the upper lip. The t-slot 176 includes an inner slot perpendicular to an outer slot. The outer slot may end at an edge of the lower lip.

The tool mating end 29 of the tool attachments 25 releasably secure to the head mating end 27. The tool mating end 29 may include a convex outer portion 182. The convex outer portion 182 forms an upper curved wall and a lower curved wall. Formed in between the upper curved wall and the lower curved wall are outer female slide slots 212 having a concave shape. A convex mid rail 184 is formed at a center of the convex outer portion 182 in between the outer female slide slots 212. A pin 186 protrudes from the upper curved wall and a threaded slot 185 is formed through the lower curved wall.

To releasably connect the tool attachments 25 to the head 14, the pin 186 is first inserted into the pin slot 178 and the tool mating end 29 is rocked into the head mating end 27. The convex outer portion 182 of the tool mating end 29 corresponds with and fits within the concave outer portion 172 of the head mating end 27. The convex mid rail 184 of the tool mating end 29 corresponds with and fits within the concave mid slot 174 of the head mating end 27. The outer male slide tabs 210 of the head mating end 27 corresponds with and fits within the outer female slide slots 212 of the tool mating end 29. The quick connect/disconnect will already be assemble to the attachments 25. Note to assemble the quick/connect disconnect, first put main spring/conical bushing spring 188 and threaded rod with main spring/conical bushing spring dispose over squared section into conical bushing 194. The squared section 192 will mate with the squared section conical bushing opening therefore making it turn all together when threading it into the threaded slot 185 of attachments 25 or FIG. 25 alternative design in head 220. The conical bushing arms will be grab to bias main spring/conical bushing spring to be pull out the slot. This will allow for the conical bushing 194 to be turn clockwise or counter clockwise while both conical bushing and threaded rod 190 and threaded rod 256 in the alternative wing nut/conical bushing FIG. 27. The tool slot 302 in FIG. 28 will allow for the threaded rod 256 to be tighten and torqued with a flat head screw driver into the thread slot 185. Note the tool slots are optional on both threaded rod 187 in FIGS. 3 and 256 in FIG. 30. The conical bushing 194 in FIG. 3 will then be released back into slot 185 by letting go of the arms 195 and main spring/conical bushing biasing the flange of threaded rod 194. The wing nut 196 will be then screwed loosely onto threads 190 of threaded rod 187. The quick connect/disconnect is now assembled on attachment 25 or FIG. 25 alternative design head 220. Note both designs are to assemble the same way and work with same principles. The quick/connect disconnect conical bushing 194 will meet with the lip of the t-slot 176 opening. The threaded rod 187 will go through opening of t-slot 176 as the conical bushing angle 276 meets the lip of t-slot 176 therefore compressing the conical bushing spring/main spring. The conical bushing spring/main spring will allow for the conical bushing to bias against threaded rod 187 flange and go over lip of t-slot 176 and allow conical bushing to rest in the perpendicular slot of t-slot 176. This will allow for the attachment 25 mating end 29 and the head mating end 27 to align up. The quick connect/disconnect wingnut 196 will be tighten. The wing nut serrated/tooth surface will engage inner radial horizontal surface of conical bushing 194 serrated/tooth surface to lock/secure attachment 25 to head 14. Note the quick connect/disconnect will be attached to the alternative embodiments FIG. 25 head 220 below lower curved wall on each side and work with same principles.

As illustrated in FIG. 25, an alternate head 220 may include a head mating end 29 having the convex outer portion 182, the outer female slide slots 212, the convex mid rail 184, the pin 186 and the threaded slot 185 to attach the quick connect/disconnect. In such embodiments in FIG. 25, alternate tool attachments 218, 222, such as a nail puller 218 and a hammer 222, may include a tool mating end 27 having a concave outer portion 172 forming the upper lip and the lower lip, outer male slide tabs, a concave mid slot 174, a t-slot 176 and a pin slot 178. In such embodiments, the head mating end 29 and the tool mating end 27 fit together as described above in a reverse configuration.

In certain embodiments, the quick connect/disconnect may include a conical bushing 194, a spring 188, a rod 187 with optional tool slot at end and a female threaded wingnut 196. The rod 187 may include a threaded body 190, a squared portion 192 and a threaded pin 193. The spring 188 may be disposed over the squared portion 192 and rest against a flange separating the squared portion 192 and the threaded body 190. The squared portion 192 and spring 188 fit within the conical bushing 194 so that an end of the squared portion 192 fits within a squared opening of the conical bushing 194 with the threaded pin 193 extending beyond the conical busing 194 to be threaded in the attachment head 25 threaded slot 185 or alternative embodiment FIG. 25 head 220 slot 185. The squared portion 192 disposed within the squared opening prevents rotation of the rod 187 relative to the conical bushing 194. The conical bushing 194 fits through the inner slot of the T-slot 176 and the threaded pin 193 mechanically fastens to the threaded slot 185 with the spring 188 disposed within an inner end of the conical bushing 194 and the flange.

In certain embodiments, the threaded wingnut 196 includes a narrow end and a serrated flange extending laterally from the narrow end. The threaded wingnut 196 may be torqued along the threaded body 190 until the narrow portion fits within the conical bushing 194 and abuts close to or against the flange. The serrated flange abuts against an inner wall of the conical bushing 194 radial circular horizontal serrated/teeth surface, preventing the threaded wingnut 196 from loosening. The conical bushing 194 tapers to a diameter larger than the inner slot of the T-slot 176. Therefore, the connector retains the tool attachment 25 to the head 14. The conical bushing 194 may further include outer arms 195 extending vertically from a bottom portion. The outer arms 195 may include a gripping portion, such as ridges, formed on an outer surface. When removing the connector from the tool attachment 25 and the head 14, the user may partially unscrew the wingnut 196 from the rod 187, pull the conical bushing 194 by the outer arms 195 against the bias of the spring until a narrow end of the conical busing 194 is able to slide out of the outer slot of the T-slot 176. The tool attachment 25 and the connector thereby quickly detach from the head 14. As illustrated in FIG. 25, the tool attachment 25 may slide off from the head 14 while the quick connect/disconnect is still connected to the head 14. Note the outer arms 195 can also be used to connect tool attachments in reverse also.

FIGS. 26 through 30 illustrate an alternate quick connect/disconnect. The connector includes a conical bushing 228, a main spring/conical bushing spring 266, a rod 226 and a threaded wingnut 224.
