Abstract
A gardening trimmer may include: a first blade connected to a first cam member and configured to reciprocate in response to rotation of the first cam member; and a second com connected to a second cam member and configured to reciprocate in opposite phase to the first blade in response to rotation of the second cam member. The first cam member includes a first eccentric cam configured to revolve around a first rotation axis and is connected to the first blade at the first eccentric cam. The second cam member includes a second eccentric cam configured to revolve around a second rotation axis and is connected to the second blade at the second eccentric cam. Each of the first and second blades is configured to reciprocate along a plane including the first and second rotation axis.

A gardening trimmer, comprising:
- a prime mover;
- a first cam member configured to be driven by the prime mover to rotate in one direction about a first rotation axis;
- a second cam member configured to be driven by the prime mover to rotate in another direction about a second rotation axis parallel to the first rotation axis at a same cycle as the first cam member;
- a first blade connected to the first cam member and configured to reciprocate in response to rotation of the first cam member;
- and
- a second blade connected to the second cam member and configured to reciprocate in an opposite phase to the first blade in response to rotation of the second cam member,
- wherein the first cam member comprises a first eccentric cam configured to revolve around the first rotation axis and is connected to the first blade at the first eccentric cam,
- the second cam member comprises a second eccentric cam configured to revolve around the second rotation axis and is connected to the second blade at the second eccentric cam, and
- each of the first blade and the second blade is configured to reciprocate along a plane including the first rotation axis and the second rotation axis.
