A tool is devised for skateboards. Thee tool includes a grip, an Allen key/screwdriver, a driver and three sockets. The grip includes a non-circular cavity in an end and a groove in a side. The first and second sockets are connected to the grip, opposite to each other. The Allen key/screwdriver is selectively inserted in the groove. The driver is selectively inserted in the cavity. The third socket is foamed at an end of the driver. The third socket includes an axial bore, a radial bore, and a cutout opposite to the radial bore.

A pin fixing type hand tool structure includes a tool head body, a grip body and an abutting fixing block, and cut corners are formed between the tool head body, the grip body and the abutting fixing block and provided for alignment and positioning, so that the three can be stably engaged with one another by the cut corners. The structure is simple and the assembling is convenient, and the production and assembling costs are reduced to achieve high structural stability and assembly convenience.

A multi-tool includes a cylindrical body and a head extended from an end of the cylindrical body, the head to be pivoted between a first position with the head aligned with the cylindrical body and a second position with the head oriented at an angle to the cylindrical body, the head including a cradle to support a segment of a roller chain.

A kitchen instrument with a replaceable head is described having a handle, an ejection shaft, and an ejection knob. The handle is mostly hollow with an opening on a first side and an opening on the second side opposite the first side. The opening on the first side includes an indent shaped to secure a replaceable head by preventing exiting from the indent and also from rotating. The replaceable head has a connector with a first connecting portion and a second connecting portion shaped to be secured in the indent. An ejection shaft is sized and arranged to be inserted in the second side and pass through the handle. The ejection shaft is sized to press on the replaceable head to eject the replaceable head. Multiple replaceable kitchen utensils in the form of replaceable heads are attachable to the same handle of the kitchen instrument.

A tool includes a first body, a rotary member, a positioning unit and an engaging unit. By the positioning unit and the engaging unit, the rotary member is positioned relative to the first body with dual-positioning feature. When the first body is rotated, the rotary member is positioned by the positioning unit and the engaging unit. The rotary member is not likely to freely rotate because both of the positioning unit and the engaging unit fail when using the tool.
