Snap spring dismounting and mounting tool

A snap spring dismounting and mounting tool, comprising:

• an outer housing, which is a hollow cavity;
• a dismounting and mounting assembly, two ends of which can be detachably clamped in the outer housing, respectively;
• a pressing rod, which is movably disposed on the outer housing and can be in contact connection with or disengaged from, the dismounting and mounting assembly;
• and
• an elastic member, which is disposed in the outer housing, is in contact connection with the pressing rod, and provides a biasing force and a restoring force to the pressing rod, respectively, wherein
• the dismounting and mounting assembly comprises a connecting mechanism, and a first clamping plier body and a second clamping plier body that are movably disposed on the connecting mechanism relative to each other;
• the first clamping plier body and the second clamping plier body have a gap disposed therebetween, and can be in contact connection with or disengaged from the pressing rod, respectively;
• and when the pressing rod is in contact connection with the first clamping plier body or the second clamping plier body, the pressing rod provides a biasing force to the first clamping plier body or the second clamping plier body, allowing the first clamping plier body and the second clamping plier body to perform biased movement relative to each other.
