The beneficial effects of the utility model are: the axle sleeve structure of the utility model dry friction clutch improves, and has increased the end face location, for the installation increase location of subsequent workpiece, guarantees the radial location of pressurization disk and multiple spot floor clip; The rotation in the using process has been avoided in the improvement of pressurization disk structure, pressurization disk can not rotated follow-up after mechanical overload takes place, the sheet wheel that goes beyond the limit of torque is in time thrown off with dry friction clutch, the protection power output system, it is sensitiveer that the back feedback is taken place overload, the Security that can improve system; Multiple spot retaining pad structure is improved, realize after the round nut locking not because in the difference of system's installation direction, and cause getting loose, continue to keep locking effect, make axially, radially all do not relatively move by two places are spacing, thereby realize the requirement of two-way installation.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, described multiple spot floor clip has a plurality of counterbores.
Further, have a plurality of bolts hole on the described nut, be equipped with socket head screw in the described bolt hole, the threaded end of described socket head screw is fixed in the counterbore.
Further, has at least one positioning hole on the described nut.
