Abstract: The present invention provides an electric pruner saw, comprising a motor (12), a wobble bearing (13) and a saw (14, 15), and further comprising a balancing component; the balancing component and saw vibrate at the same frequency in parallel directions, but the phases of vibration of the balancing component and saw differ by 180°, such that the opposite-phase vibration of the balancing component partially or completely offsets the vibration of the saw. Furthermore, the wobble bearing in the pruner saw is arranged at an upper side of the motor, such that a rotating rod of the pruner saw is located between the motor and a saw rod; thus, the wobble bearing is closer to the saw rod, so the length of a swing rod of the wobble bearing is shortened, and consequently the various components are arranged more compactly, thus reducing the volume of the pruner saw.

Abstract: The present utility model provides a reciprocating saw clamping device, the clamping device being mounted on a machine body of the reciprocating saw, close to a cutting saw blade located at a front end of the machine body of the reciprocating saw, and being configured to clamp an object to be cut when the reciprocating saw is performing a cutting operation, wherein the clamping device comprises a clamp and a clamp support, the clamp and clamp support being rotatably hinge-connected, and the clamping device is removably mounted on the machine body of the reciprocating saw by means of positioning structures which fit each other and are arranged on the clamp support and a housing of the reciprocating saw. The present utility model also provides a reciprocating saw having the clamping device. The reciprocating saw clamping device of the present utility model is not only structurally simple and convenient to operate, but can also satisfy cutting requirements of different sizes, with a larger range of operations.
