A tool for applying a circular indicia onto a surface, such as a ceiling, wall or other flat surface, with a marking implement has a base that includes a first side with a center punch projecting away therefrom. At least one marker holder is fixed with a second side of the base and configured to hold the marking implement therein, such that a marking point of the marking implement projects through a marking aperture traversing the base. A handle is selectively removable from the base and is adapted for selective engagement with the center punch to assume a collapsed configuration.

A device for positioning photographs and the like with respect to each other so that they may be moved as a group as they are repositioned over (or removed entirely from) a workpiece such as a scrapbooking page. In alternative embodiments, the device also serves as a platform for other scrapbooking tools (cutting blades, pens, etc.) that can be applied to one or more of the photographs.

An adjustable rotary structure comprises a first restricting assembly, a second restricting assembly, a rotary member and a positioning seat. The rotary member is formed with a restricting hole and a shift hole. The positioning seat is formed with a positioning groove, a restricting circular groove and a restricting elliptic groove. The first restricting assembly is positioned on the positioning groove by the restricting hole in such a manner that the restricting hole of the rotary member abuts against the positioning groove and is restricted on the positioning seat. The second restricting assembly is selectively positioned in the restricting circular groove or the restricting elliptic groove via the shift hole, so that the rotary member is forced to rotate along a circular path or an elliptic path.

A drawing instrument includes a turning assembly including a handle, a post having an end center, a bevel gear rotatable about the post, and a lower extending socket; a gear assembly meshed with the bevel gear and including a wheel; a link assembly including a first link having an upper end pivotably secured to the wheel, and a second link pivotably secured to a lower end of the first link and having a lower portion received in the socket; and a drawing assembly including an arm including a scale and a groove, a wheeled support secured to the arm, a third link pivotably secured to the second link and the groove, a slider pivotably secured to the third link and adapted to slide in the groove, and a pen mounting bed adjustably fastened at the groove. Rotating the handle will cause the pen mounting bed to draw an ellipse.

A multi-purpose hand tool has a first member having a first portion and a second portion. A second portion member is slidably and pivotally coupled to the second portion of the first member. A coupling assembly pivotally couples the second member to the second portion of the first member and allows the second portion between a first position proximate a first end of the second portion in which the multi-purpose hand tool can be used to obtain a measurement for a first marking or scribing operation, and a second position proximate a second end of the second portion opposite the first end thereof in which the multi-purpose hand tool can be used to obtain a measurement for a second marking or scribing operation different from the first marking or scribing operation, thereby providing a multi-purpose hand tool reconfigurable for a plurality of purposes.

The Thread Ruler and Multi-Function Drafting Instrument is a single instrument designed to draw circles, ellipses and parallel lines, and which includes features that allow the instrument to function as protractor, a ruler and a drawing compass. The instrument has a slide ruler that holds a marking device and that has a stem with a thread attached. The thread is further attached to the main ruler body at an outer end of the protractor so that ellipses can be drawn. The instrument may be used on any flat marking surface including: paper, drafting table, chalkboard and dry erased board. The instrument may be adapted to be used in portable manner so that it can be placed in shirt pocket.

A manipulator of a compass for drawing a circle or a compass-cutter for cutting an object in circular configuration is provided with a mechanism for transmitting the force from the user's hand only in one direction. With such the construction, a user can smoothly draw a complete circle at 360 degree, or can cut a paper, a cloth and so on in circular configuration, without re-pinching the manipulator during operation, in a manner for a ratchet which is a commercially available tool.

A compass cutter comprises a main body fastened with an extension rod which is connected with a slidable seat slidable along the extension rod. The main body is further provided with a locating block, a protective cover, a blade, a fixation block, and an insertion pin. The slidable seat is provided with a locating block, a connection rod, a locating pin, and a shield. The compass cutter can be expanded, thanks to the extension rod. The locating pin and the blade are shield by the shield to protect the user of the compass cutter.
