A male plug connection member is disposed within the blade mount aperture and preferably has bowed spring arms which are resiliently inwardly deformable, which are urged inwardly upon insertion into the female blade receptacle. The spring arms flex outwardly upon passage through the female receptacle. A multitool retention device is disclosed having a mount aperture end adapted to receive the receptacle and a tool retention end comprising at least one tool retention arm defining an elongated retention slot configured to slidingly receive and retain at least one tool member having a flange at one end of the tool member.

Abstract: A cutting blade for use with a rotary trimmer head assembly configured with one or more swiveling blade receptacles is disclosed. The blade has a trimmer head connecting end portion defining a blade mount aperture adapted to receive the swiveling blade receptacle, and the blade has a cutting end portion. The connecting end portion comprises a spring collar assembly sized and configured to firmly and removably receive and secure a portion of an outer cylindrical surface of the swiveling blade receptacle. The spring collar assembly has a pair of opposing levers having two ends. Each lever has a handle and a curved jaw. The curved jaws define a collar aperture in coaxial alignment with the blade mount aperture. Preferably, the levers are fixedly connected to respective pivot arms radially extending from a pivotal abutment disposed intermediate the two ends of each lever, wherein squeezing together said handles of the levers increases a diameter of the collar aperture.

Abstract: An apparatus including a rotary head assembly, which is configured to allow replacement of at least one cutting member. The rotary head assembly includes at least one spring biased cutting member receptacle sized and configured to receive at least one cutting member.

Abstract: A protective glider assembly for a handheld trimmer apparatus includes a glider plate operatively connected to a glider shaft. A bearing acts between the glider plate and glider shaft. The protective glider is configured to rotate or remain stationary independent of and relative to rotation of a rotary head of the handheld trimmer. The glider plate is positionable relative to the rotating head to adjust cutting height of trimmer members. A first series of trimmer members are connected to the head in a first plane which is generally parallel to a second series of trimmer members connected to the head in a second plane. The rotary head forms a trimmer member passage therethrough and includes a fastening mechanism having a pivotally moveable engaging member configured to clear the passage and to extend through a mount aperture of a trimmer member when positioned in the passage.
