A device for holding a cutting blade having a cam, including a blade pivot pin for mounting the cutting blade in a pivoting manner on a cutting tool, and a cam pivot pin connected to a driving mechanism of the blade, a first pivot pin chosen from the blade pivot pin and the cam pivot pin being provided with a matching-shape axial lock. The other pivot pin is provided with a manually tightened axial lock. The device includes a catch having a first end with a latch able to be engaged with and held on the first pivot pin by matching shapes, and a second end able to be engaged with and held on the pivot pin provided with the manually tightened axial lock.

Presented here are toollessly releasable, interchangeable handles for hand tools and methods of use thereof. Hand tool users often experience discomfort and injury because hand tool handles are not well suited to each user's hands. In addition, different hand tools have different handles, so users that switch between hand tools often find a different level of comfort with different hand tools. The disclosed platform for interchangeable handles for hand tools allows a user to attach handles custom fitted to their hand to any corresponding hand tool, and likewise allows different users to share a hand tool by detaching the first user's handles and then attaching a second user's handles. Various embodiments for connecting interchangeable handles to hand tools are shown. Additionally, a fluid reservoir disposed within an interchangeable handle and locking mechanisms for keeping the interchangeable handles attached to the hand tool are disclosed.

A gardening shears includes a shank having an elongated groove, a first handle connected to the bottom end of the shank, a first shear blade having a first blade portion and a first shank portion with top end connected to the bottom end of the first blade portion, a second handle connected to the bottom end of the first shank portion, and a second shear blade having a second blade portion and a second shank portion with top end connected to the bottom end of the second blade portion. The first shank portion has an axle assembly located in the elongated groove. The second shank portion is pivotably connected with the first shank portion and the shank by first and second pivot members respectively. When the handles are opened or closed, the axle assembly moves along the elongated groove to change the torque on the handles to save effort.

Problems to be Solved

To provide an unmanned aerial vehicle capable of achieving both of equipping a pruning structure capable of pruning trees and enhancing safety.

Solution

An unmanned aerial vehicle 2 according to the present invention includes a pruning structure 23 capable of pruning a tree; a housing structure 24 capable of housing the pruning structure 23 inside; and a state control section 212 capable of controlling the state of the pruning structure 23 between a housed state in which the pruning structure 23 is housed inside the housing structure 24 and an exposed state in which the pruning structure 23 is exposed to the outside of the housing structure 24, wherein the state control section 212 can control the state of the pruning structure 23 to the housed state on landing. The state control section 212 preferable to control the state of the pruning structure 23 to the exposed state when a distance from the unmanned aerial vehicle 2 to a target tree to be pruned equal to or shorter than the predetermined distance, and to control the state of the pruning structure 23 to the housed state when a distance from the unmanned aerial vehicle 2 to the target tree longer than the predetermined distance.

A hand tool including a shear assembly is provided. The hand tool includes a first handle, a second handle, a cutting blade, and a linkage. The first handle forms a channel extending along a reference axis corresponding to an extension of the first handle. The second handle includes a cutting member. The cutting blade forms a first opening and a second opening. The linkage is attached, via a first fastener, in pivotal arrangement to the first handle at the channel and to the cutting blade at the second opening. The cutting blade is attached, via a second fastener, in pivotal arrangement to the second handle at the first opening.

A multipurpose tool, such as a pruning shear that incorporates a pruning saw into a single handheld tool. The pruning shear includes pruning handles with a folding saw blade that pivotally deploys from a stowed position within one of the pruning handles to an extended operational position.
