Embodiment Construction

[0042] The following description of the preferred embodiments is exemplary only, and does not constitute a limitation on the combination of features necessary to practice the invention.

[0043] refer to Figure 1-Figure 3 , the pruning tool 10 includes a housing 12 , a cutter head 14 , a motor 16 and a transmission 18 driven by the motor 16 . Housing 12 can be split type, from figure 1 and figure 2 It can best be observed in the comparison of , which includes the first half 12a and the second half 12b. exist figure 2 1, the first or upper half 12a of the housing (as shown) has been removed to reveal the internal components of the pruning tool 10.

[0044] Motor 16 may comprise a permanent magnet DC motor, however, any suitable motor known to those skilled in the art could also be used in pruning tool 10 of the present invention.

[0045] The cutter head 14 includes a first trimming member 20 and a second trimming member 22 . The first trimming member 20 is pivotally m...

Abstract

A cutting tool has a cutting head, a motor and a transmission means drivable by the motor. The cutting head comprises first and second cutting members, wherein the first cutting member is pivotably moveable with respect to the second cutting member. At least the first cutting member is drivable by the transmission means between a first angular position with respect to the second cutting member and a second angular position with respect to the second cutting member, in which a space between the respective cutting blades is closed. The transmission means is a bevel gear on the output shaft of a gearbox which conveys drive power from the motor to the drive gear. The bevel gear directly engages a bevel wheel member connected to the first cutting member and which swivels with the first cutting member about the same swivel point. A controller comprises main, first and second switches which control the motor to move the first cutting member (movable blade). The main switch acts as a main power switch whereas the first and second switches act as limit switches detecting movement of said movable blade at the limits of its intended motion. The controller exerts automatic control over movement of the first cutting member in response to inputs from the first and second limit switches.

Description

technical field [0001] The present invention relates to an electric pruning tool of the type such as secateurs and pruning tools, which is particularly, but not exclusively, suitable for pruning vegetation such as shrubs or branches. Background technique [0002] Manually driven pruning tools and secateurs are known. Electric pruning tools and secateurs are also known in which a motor is provided to drive at least one blade of a pair of blades relative to the other blade of the pair. EP2158805 discloses an example of such an electric pruning tool. Problems associated with known motorized pruning tools and secateurs include efficient transmission of drive from the motor to at least one movable blade and automatically controlling said at least one blade in its open position in a safe, user-friendly and efficient manner. position and the closed position. [0003] purpose of invention [0004] It is an object of the present invention to alleviate to some extent or obviate on...
