An angle adjustable connecting part for farm equipment and hand tools easily detaches from a working part of farm equipment and a hand tool from a sack. A connecting part is formed on the front end of a working part of farm equipment or hand tool. A connecting part is also formed on the front end of a sack, thereby coupling the working part and the sack. The connecting part has a fixing hole formed in the center thereof, and multiple angle adjusting holes are formed concentrically outward. A fixing hole is formed at the center outward from the connecting part. A fixing plate has a fixing protrusion inserted into the angle adjusting hole. When a fixing screw is fixed to the fixing plate and the fixing hole of the connecting part, the fixing protrusion of the fixing plate is fixed to an angle adjusting hole of the connecting part.

Holder (1) for releasably connecting a handle to a tool (2), in which the holder (1) comprises a space (3) in which a handle end is introducible, in which this space (3) comprises a wall surface with one or more projecting cutting elements (5a, 5b) for cutting complementary screw thread by means of which the one or more cutting elements (5a, 5b) are releasably connectable, in which the holder (1) comprises a coupling portion (6) comprising the one or more cutting elements (5a, 5b) and a retaining portion (7), in which the coupling portion (6) is made of a first material comprising plastic and the retaining portion (7) is made of a second material, in which the hardness of the first material is greater than the hardness of the second material.

A leverage extending tool is provided. The device includes an elongated body having a first end and a second end. The first end includes a working end. The working end can include a box wrench, an open ended wrench, or a ratchet wrench. The second end includes a socket adapter aperture. The socket adapter aperture is linearly aligned with the elongated body. The socket adapter aperture includes a rectangle opening linearly aligned with the elongated body. The socket adapter aperture further includes smooth inner faces. The socket adapter aperture is adapted to receive a socket wrench or a breaker bar. This allows the user to apply additional torque to the wrench.

An offset connector subdivides a long, slender tool or implement handle. The offset connector may be provided with one or more unitary or replaceable grips. The additional grips serve as secondary or tertiary hand holds that enable more adaptable and capable ergonomic manipulation of the tool or implement. The offset connector is inserted intermediate between a primary handle grip and the tool or implement head, thereby subdividing the long slender tool or implement handle into at least two separate handle segments. Each handle segment is inserted into a handle segment receiver socket, and is affixed therein using a bolt, screw, or other fastener that is longitudinally co-axial with the longitudinal axis of the handle segment. Some embodiments establish fixed spacing between the primary handle, secondary handle, and implement. Other embodiments provide variable spacing therebetween.
