Abstract:
A quick-change connecting mechanism and a quick-change screwdriver of the invention. Firstly, a connecting handle and an accommodating cavity are matched in a shaft-hole mode, during actual production and machining, the machining precision of round shafts and round holes is high, the matching and mounting precision of the round shafts and the round holes is much higher than that of hexagonal shafts and hexagonal holes, and thus the axial precision of the connecting handle or screwable tips is ensured after mounting; secondly, longitudinal locking bodies are arranged and longitudinally inserted into locking grooves in an abutting mode under the effect of a sliding sleeve, so that rotation torque is transmitted in the circumferential direction, and the torque of a connecting rod is transmitted to the connecting handle or the screwable tips. Meanwhile, the connecting handle is fixed in the mounting direction and is prevented from falling.

Claim (Index 1):
A quick-change connecting mechanism, comprising:\n a connecting rod and a connecting handle, wherein the connecting rod is provided with an accommodating cavity which extends along a rotation axis, one side of the accommodating cavity is open, and the connecting handle is placed and accommodated in the accommodating cavity from the open side; the accommodating cavity is provided with mounting through holes penetrating into the accommodating cavity in the radial direction; locking bodies, wherein the locking bodies are arranged in the mounting through holes and can move in the mounting through holes to get close to or away from the connecting handle; a sliding sleeve, wherein the sliding sleeve is movably mounted on the connecting rod and has a locking position and a release position; when located at the locking position, the sliding sleeve abuts against the locking bodies and enables the locking bodies to be inlaid in the accommodating cavity to abut against the connecting handle; when located at the release position, the sliding sleeve releases the locking bodies and enables the locking bodies to be separated from the connecting handle; wherein: the connecting handle is provided with a cylindrical positioning section, correspondingly, the accommodating cavity is provided with a mounting hole matched with the positioning section, and the mounting hole is coaxial with the rotation axis of the connecting rod; the connecting handle is mounted in the accommodating cavity, the positioning section is mounted in the mounting hole so as to be matched with the mounting hole, and thus the connecting handle is accurately positioned in the axial direction; locking grooves are further formed in positions, corresponding to mounting through holes, of the connecting handle; when the sliding sleeve is located at the locking position, the locking bodies can stretch into the accommodating cavity and be inserted into the locking grooves, and thus the connecting handle is fixed in the rotation direction of the connecting rod.
