A portable cleaning device with interchangeable cleaning tools and an alert system may include an elongate rod having a first end and a second end, a handle attached to the first end of the rod, a cleaning attachment removably engaged with the second end of the rod, a handle grip sensor operatively attached to the handle and a cleaning attachment pressure sensor operatively attached to the cleaning attachment, and an indicator operatively attached to each sensor, the indicator designed to alert a user when the sensor is activated.

The invention provides a dual-purpose handle, comprising a body, wherein mounting holes are provided in the body and are used for connecting to functional members; the mounting holes are provided in the body in both an axial direction and a radial direction; axial and radial mounting holes provided in the body can enable the handle and the functional members to easily and quickly switch between two connection forms, i.e. straight and T-shaped; and torsional torques that are different in magnitude can be output by means of different connection manners under the action of the same operation force. Clamping devices fitted with the functional members are arranged in the mounting holes; and when the functional members are connected to the handle, the clamping devices can fix the functional members and prevent same from rotating in a cavity of the body of the handle. The axial and radial holes of the handle are configured to be through holes, so that the handle can be adapted to guide needles of different sizes passing through same and is suitable for minimally invasive surgery, thereby further expanding the range of use of the handle.

An adjustable tool holder is configured for interchangeable use with a variety of tools provided with different connection elements. The connection elements include at least a first connection element configured for a first manner of connection with the tool holder and a second connection element configured for a second manner of connection with the tool holder. The tool holder includes a distally extending tool support operable to detachably support each of the tools. The tool support includes a first tool connector configured to releasably connect with the first connection element in the first manner of connection. The tool support includes a second tool connector configured to releasably connect with the second connection element in the second manner of connection.

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.

The present disclosure provides a multifunctional tool kit. The multifunctional tool kit knit includes a connecting piece, a cover, a tool, a first shank, and a second shank. The cover is connected to an upper end of the connecting piece. The first shank and the second shank are connected to a lower end of the connecting piece. The tool is inserted into a second hole to reach the bottom of a pin hole. By rotating the cover, the tool is locked on the connecting piece. The first shank and the second shank are movably connected to the connecting piece, and are reversely rotatable by 180 degrees to engage with each other define a handle. The present disclosure achieves effects of saving space and resources, and implementing multiple integrated functions with one tool.

A hand tool assembly includes a handle having a connection portion formed on one end thereof by way of blow molding, and the connection portion includes a recess defined therein which includes a first inner bottom. At least one hole is defined through the first inner bottom of the recess. A head has the top thereof accommodated in the recess and includes at least one rod which is engaged with the at least one hole. At least one function part is connected to the underside of the head and protrudes beyond the recess. A board is connected between the head and the first inner bottom of the recess such that the head is replaceable.

A modular motorcycle tool kit comprising multiple tool drivers and a plurality of attachable tool components said kit being configured to address most motorcycle repair or service needs. Three drivers include apertures and special step-key shank slots to engage and receive a plurality of tool insert bits and fastener tool heads. The fastener tool heads are coupled to unique step-key shanks which are stronger, more robust, and less expensive to manufacture than comparative fastener tool head shanks. The drivers can be used separately or in conjunction with one another depending on the need of the user. The modular motorcycle tool kit is specifically designed and configured to be an invaluable modular motorcycle tool and at the same time occupy very little space on the motorcycle.
