1. An outlet structure for an encoder, the structure comprising:
an encoder case with a first cable through-hole disposed therein, the first cable through-hole allowing a first cable to pass therethrough;
a metal ring disposed in the first cable through-hole, the metal ring deformable under an external force to clasp a shielding layer of the first cable;
a fixing member with a second cable through-hole disposed therein, the second cable through-hole allowing the cable to pass therethrough, the fixing member fitting with interference into the first cable through-hole from an outer side of the encoder case for fixation;
a first O-shaped ring fitting around the fixing member, and fitting within the first cable through-hole to seal a slit between the fixing member and the encoder case; and
a second O-shaped ring disposed in the second cable through-hole and fitting around the cable, the second O-shaped ring capable of sealing a slit between the fixing member and the cable, and the second O-shaped ring applying an elastic force to the metal ring after the fixing member is inserted into the first cable through hole, such that the metal ring remains abutting against the encoder case.
