The present invention relates to a pry tool with dual heads and, more particularly, the head is rotatable to various angular orientations.
Taiwan Pat. No. M310787 discloses a structure-improved pry tool. The pry tool includes an elongated shaft and two claws. The shaft is hollow and has a slightly flat cross section. The two claws are solid. A first claw is coupled to a first of two ends of the shaft. The first claw includes a fix end inserted in the hollow of the shaft and welded to the first end of the shaft. A second claw is coupled to a second of the two ends of the shaft. The second claw includes a fix end inserted in the hollow of the shaft and welded to the second end of the shaft.
When using such pry tool, users often use one hand to grip on the claw not used in order to apply force efficiently. The users, however, are easily scratched by the flat and sharp corners of the claw.
The present invention is, therefore, intended to obviate or at least alleviate the problems encountered in the prior art.
A dual-headed pry tool with rotatable head includes a first tool component provided with a first tool head useful for prying objects at a first end thereof and a first pivot connection at a second end thereof respectively, and a second tool component provided with a second tool head useful for prying objects at a first end thereof and a second pivot connection at a second end thereof respectively. The second pivot connection is pivotally connected to the first pivot connection to allow the first and the second tool components to pivotally connect with each other. The second tool component is rotatable relative to the first tool component about a pivot axis which extends along a longitudinal direction between the first and the second ends of the first tool component. Each of the first and the second tool heads has an orientation with respect to the pivot axis, and a relative angle between the orientations of the first and the second tool heads changes as the second tool component rotates relative to the first tool component.

Other objectives, advantages, and new features of the present invention will become apparent from the following detailed description of the invention when considered in conjunction with the accompanied drawings.
The first tool component 20 is provided with a first tool head 21 useful for prying objects at a first end thereof and a first pivot connection 22 at a second end thereof respectively. The first tool component 20 forms a shaft useful as a lever interconnecting the first tool head 21 and the first pivot connection 22. In the embodiment, the shaft is solid but can be hollow. The first tool head 21 is provided with an edge 211 at a distal end thereof which extends along a straight line, a pulling surface 212 at a first surface thereof configured to bear an object to be pried, and a supporting surface 213 at a second surface thereof, which is opposite the first surface, configured to abut against a surface to be pulled apart from the object to be pried. The edge 211 of the first tool head 21 is notched that is adapted for engaging with a nail to be pried. The pulling and the supporting surfaces 212 and 213 extend oppositely from the edge 211. The pulling surface 212 is concave. The supporting surface 213 is convex.
The second tool component 30 is provided with a second tool head 31 useful for prying objects at a first end thereof and a second pivot connection 32 at a second end thereof respectively. The second tool head 31 forms a claw. The second tool head 31 is notched that is adapted for engaging with a nail to be pried. The second pivot connection 32 is pivotally connected to the first pivot connection 22 to allow the first and the second tool components 20 and 30 to pivotally connect with each other. The second pivot connection 32 is provided with a hole. An inner periphery of the second pivot connection 32 defines the hole. The first pivot connection 22 is inserted and rotatable in the hole.
Further, the dual-headed pry tool 10 further includes mechanisms to prevent detachment between the first and the second pivot connections 22 and 32. The first pivot connection 22 is provided with a limiting section 221 and the second pivot connection 32 is provided with an anti-disengagement section 321 respectively. The limiting section 221 and the anti-disengagement section 321 abut against one another to prevent disengagement between the first and the second pivot connections 22 and 32. The limiting section 221 has a shape which has a small diameter end adjacent to the first tool head 21 and a large diameter end distal to the first tool head 21. The large diameter end of the limiting section 221 is of a diameter D. The shape of the limiting section 221 is conical. The limiting section 221 in cross section includes two lines, which extends along outer peripheral edges thereof and from the large diameter end toward the small diameter end, converging toward one another and intersecting at a vertex point P. The vertex point P is positioned at a distance from the large diameter end and the distance defines a height H. The ratio of the diameter D to the height H is more than 0.2 and less than 0.4. The anti-disengagement section 321 forms a conical hole corresponding to the shape of the limiting section 221. The anti-disengagement section 321 is shaped by applying an external force to an outer periphery of the second tool component 30 and deforms into a shape matching the limiting section 221. The anti-disengagement section 321 is on the inner periphery of the second pivot connection 32. The inner periphery of the second pivot connection 32, which defines the anti-disengagement section 321, is in surface contact with an outer periphery of the limiting section 221. Further, the second tool component 30 is provided with a resilient member 33 arranged in the hole defined by the second pivot connection 32 and opposite ends of the resilient member 33 respectively abut against the bottom of the hole of the second pivot connection 32 and the first pivot connection 22 to urge the limiting section 221 and the anti-disengagement section 321 to abut against one another. Further,
In addition to the anti-disengagement section 321, the first pivot connection 22 is provided with a rod section 222 adjacent to the limiting section 221 and the rod section 222 is received by the second pivot connection 32. The hole of the second pivot connection 32 is provided with a tube section 322 in which the rod section 222 is disposed. The resilient member 33 abuts against the rod section 222 and disposed opposite the limiting section 221. The rod section 222 is cylindrical and the tube section 322 is circular.
The second tool component 30 is rotatable relative to the first tool component 20 about a pivot axis L which extends along a longitudinal direction between the first and the second ends of the first tool component 20. Each of the first and the second tool heads 21 and 31 has an orientation with respect to the pivot axis L, and a relative angle between the orientations of the first and the second tool heads 21 and 31 changes as the second tool component 30 rotates relative to the first tool component 20.
In view of the foregoing, a user can grip on the first tool component 20 to exert force, especially on the position close to the first tool head 21 in order to apply force more efficiently, and when using the second tool head 31 to pry an object, the second tool component 30 can be rotated to an orientation in which the second tool head 31 faces opposite a downward facing direction of the pulling surface 212 of the first tool head 21 (as shown in
Although specific embodiments have been illustrated and described, numerous modifications and variations are still possible without departing from the scope of the invention. The scope of the invention is limited by the accompanying claims.
