Claim:
A transmission member with torque-restricting protective structure, comprising: a first transmission section; a second transmission section inserted into the first transmission section; a first chucking section connected with the first transmission section and having a first chucking end facing the second transmission section; a second chucking section slidably connected with the second transmission section and linearly reciprocally movable between a chucking position and a releasing position, the second chucking section having a second chucking end, when the second chucking section is positioned in the chucking position, the second chucking end being engaged with the first chucking end, when the second chucking section is positioned in the releasing position, the second chucking end being disengaged from the first chucking end; a resilient member for resiliently locating the second chucking section in the chucking position; and an anti-rotating section disposed between the second chucking section and the second transmission section for preventing the second chucking section and the second transmission section from rotating relative to each other, wherein the first transmission section has a straight tubular body with a predetermined length, a first transmission end being disposed at a first end of the tubular body, wherein the first transmission end is a polygonal hole coaxial with the tubular body.
