An auxiliary handle accessory attaches to a shovel's handle-shaft via a folding “clamshell” type clamp, with an intermediate stem member attached to the clamp, and a grip handle screwed into this intermediate stem member, completing the assembly. The intermediate stem member has a ball-knob at the bottom that becomes entirely enclosed by half-sphere “cups” in each of the clamshell clamp halves. When these clamshell-halves close together, they form a simple yet robust socket around the ball, and comprise a ball-and-socket joint. Advantageously, the clamshell-clamp halves are bolted together, insuring a strong and robust connection. This design accommodates the “to-and-fro” motion in the vertical axis during shoveling.

A tool and method of securing a clamp is provided. The tool includes a first handle having a first jaw portion on one end. An arm is pivotally coupled to the first handle, the having a second jaw portion on one end. A second handle is adjacent the first handle. A force adjustment mechanism is rotatably coupled between the arm and the second handle. The force adjustment mechanism has a biasing member operably coupled between the arm and an adjustment member, the force adjustment mechanism further having at least one bearing member disposed between the arm and the adjustment member. The second handle is arranged to rotate relative to the arm based at least in part on a force applied on the second handle by the biasing member via the at least one bearing member.

A hot stick accessory with an attachment interface engageable with multiple types of attachment interfaces, including an shotgun-type attachment interface and a universal-type attachment interface. The accessory includes any of several operative components, such as a knife. The interface includes an attachment member with a first aperture and a plurality of second apertures arranged in an arc shape about the first aperture.

A hair brush with double-sided comb teeth includes two comb teeth portions with different types of comb teeth arranged and implanted on both upper and lower surfaces of an elastic clip cushion of the hair brush respectively, and a multiple of through holes formed at the periphery of the elastic clip cushion and provided for positioning. With the effects of a brush handle and a cover frame, the elastic clip cushion is clamped at a receiving slot of the brush handle, and the total area of the elastic clip cushion is slightly greater than the area of the receiving slot of the brush handle, and one of the end surfaces of the elastic clip cushion may be arched into an arc shape and the other end surface is naturally formed into a corresponding arc recession. The comb teeth portion with the arched surface is used as a hair brush, and the comb teeth portion with the recession is situated in a concealed status. When a user wants to switch the comb teeth portions, the user simply applies an appropriate pushing force to change the originally ached end surface into the recession, so as to complete the switch of the comb teeth portions.

An obturator assembly with a rotatable and cannulated obturator shaft for inserting a cannula into a human joint space. The obturator assemblies includes an elongated body having a proximal end and a distal end with a channel extending along an inner surface of the elongated body. The obturator assembly also includes a locking mechanism connected within the elongated body. The locking mechanism is rotatable between a first configuration and a second configuration. A cannulated obturator shaft is attached to the locking mechanism and is rotatable between the first configuration and the second configuration via the locking mechanism. The obturator assembly has a latch assembly connected to the cannulated obturator shaft which is rotatable between the first configuration and second configuration via the locking mechanism. The latch assembly securely and removably attaches to a cannula.

A fan clutch wrench is provided, including a rod and a driving member. The driving member includes a longitudinal direction and a thickness direction, two opposite ends of the driving member on the longitudinal direction are respectively defined as a first end and a second end, the second end is rotatably connected to the rod, an engagement hole penetrates through the first end in the thickness direction, the engagement hole penetrates through the first end to form a first lateral opening along a direction which is lateral to the thickness direction and lateral to the longitudinal direction, and the first lateral opening is for a fastener of a fan clutch to pass therethrough to be engaged with the engagement hole.

A bucket separating tool for removing a first bucket that has been nestled within a second bucket is provided. The bucket separating tool is a T-shaped tool having a horizontal member that is hingedly attached to a vertical member. The horizontal member includes an end having a curved edge configured to engage the lower edge of the lip of a first bucket, which is nestled in a second bucket. The vertical member includes an end having a curved edge configured to securely engage the upper edge of the lip of the second bucket. In operation, a user engages the lips of two stacked buckets with the curved edges and applies a rotational force on the vertical member to separate one bucket from the other.

An adjustable knockdown tool includes a coupling member, a blade support, and an actuator. The coupling member includes a housing defining a channel. The housing includes an actuator receptacle and a locking element that is located between the actuator receptacle and the channel. The locking element is movable between locking and releasing positions. The blade support extends through the channel and is coupled to a blade member. The blade support is rotatable relative to the channel when the locking element is at the releasing position so as to change an angle of the blade member, and the blade support is fixed relative to the channel when the locking element is at the locking position so as to fix the angle of the blade member. The actuator is configured to be coupled to the actuator receptacle to cause the locking element to move from the releasing to the locking position.

A driver with two operating positions has a handle with a first shell and a second shell connected that can open with respect to each other. Attached to one of the handle portions is a working end that is configured to rotate substantially, generally ninety degrees between a first position with a working end extending along an axis that is longitudinal with the handle and a second position with the working end extending along an axis that is transverse to the handle.
