Abstract:
1. A hand tool with a swinging structure, comprising: a head section; a handle connected with the head section via at least one swinging joint; and a shift button and a resilient unit disposed at the swinging joint, wherein: the swinging joint is composed of a first pivot end and a second pivot end pivotally connected with each other, the first pivot end being a lug an outer circumference of which is formed with several teeth; the second pivot end being U-shaped and including a first and a second lugs side by side arranged and spaced from each other by a certain distance and a base section connected between the first and second lugs, the first and second lugs defining therebetween a cavity, the first pivot end being inserted in the cavity; a shaft being fitted through the two lugs and the first pivot end, whereby the head section can swing relative to the handle, the first pivot end being spaced from the base section of the second pivot end by a space; a stopper section being fixedly disposed on an inner face of the second pivot end in the space as a step protruding from the base section; the shift button is reverse U-shaped and has a front end face, the front end face of the shift button being formed with at least one tooth, a stopper block being formed on an inner face of the shift button, the shift button being transversely and back and forth movably positioned in the space; the resilient unit is disposed between the base section of the second pivot end and a rear end of the shift button, the resilient unit serving to resiliently push the shift button forwardly toward the first pivot end, whereby the tooth of the shift button keeps engaged with the teeth of the first pivot end; and when the shift button is engaged with the first pivot end, a bottom face of the stopper block is higher than the stopper section, when the shift button is shifted toward the first lug into a disengaged position, the stopper block being positioned on one side of the stopper section, permitting the shift button to be resiliently moved rearward, when the shift button is horizontally shifted toward the second lug into an engaged position, the stopper block being just positioned in front of the stopper section and stopped by the stopper section, whereby the shift button cannot be moved rearward.
