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 10):
The quick-change screwdriver according to  claim 9 , wherein screwable tips with different specifications are formed at the front end and the rear end of the connecting handle separately; the positioning section is formed on the middle section of the connecting handle, and the locking grooves are formed in the positioning section.
