The invention relates to a multi-section universal tool. The multi-section universal tool comprises an assembling piece, a connecting piece, a working piece and two elastic pieces, wherein the assembling piece is provided with an assembling part and a first accommodating groove, and a first concave part is formed on an inner wall of the first accommodating groove; the connecting piece comprises asecond ball head and a second accommodating groove, the second ball head is provided with a second elastic propping piece which is normally propped outwards in a radial direction, a second concave part is arranged on an inner wall of the second accommodating groove, and the second ball head is inserted into the first accommodating groove and can slide in a first position and a second position relative to the first accommodating groove; the working piece comprises a third ball head and a working part, the third ball head is provided with a third elastic propping piece which is normally proppedoutwards in the radial direction, and the third ball head is inserted into the second accommodating groove and can slide in a first position and a second position relative to the second accommodatinggroove; and one of the two elastic pieces is elastically propped between the first accommodating groove and the second ball head, and the other elastic piece is elastically propped between the secondaccommodating groove and the third ball head.
Description
technical field [0001] The invention relates to a multi-joint universal tool. Background technique [0002] The universal joint is a hand tool that can be used for multi-angle rotation. It is generally used for rotating between assembled rotating tools (such as wrenches, pneumatic or electric tools, etc.) and locking elements (sleeves or screw locks, etc.). Connecting tools, the existing universal joint includes a ball seat and a drive rod, one end of the drive rod is provided with a ball head, the ball head is slid on the ball head seat in a non-rotatable manner, and the drive rod can be opposite to the ball head The seat is slidably set at a fixed position and a swing position. When the drive rod is at the fixed position, the radial convex part of the drive rod is locked against the ball seat and cannot swing relative to each other. When the drive rod is opposite to the When the ball seat is pulled outward to the swing position, the radial convex part of the drive rod can...
