Abstract: An easy-to-hold off-axis pen has a pen head, a barrel, and at least one forefinger support. The pen head is irregularly shaped and hollow. The barrel is connected with the pen head and is hollow to accommodate a cartridge and to be held. A detachable clip fastener is strip-shaped whose two ends are respectively disposed on the pen head and an off-axis part of the barrel. One end of the detachable clip fastener can be pulled by fingers. The at least one forefinger support is disposed on a sidewall of the off-axis part to support and locate the forefinger during writing. The present invention can further include middle finger abutments disposed on the off-axis part and thumb anti-slip parts disposed on the barrel to make the easy-to-hold off-axis pen easy to grasp and anti-slip, and make users comfortable to grasp.

Abstract: A marker pen has a penholder, a bending assembly and a writing part. The bending assembly is mounted on the penholder and includes a bending angle, a first section and a second section. The first section and the second section are connected with each other. The first section is connected to the penholder. The writing part is made of fibers being able to contain ink, is mounted through the bending assembly and is inserted in the penholder. Therefore, it is convenient for a user to hold the marker pen in the hand to meet different situations and the user's line of sight to the writing area is not obscured.

Abstract: A computer enclosure includes a chassis configured for securing a power supply therein. The chassis includes a bottom plate and a rear plate generally perpendicular to the bottom plate. A positioning structure is formed on the rear plate and configured for blocking the power supply from moving on the rear plate. A resiliently deformable latch piece is located on the bottom plate. A blocking portion is located on the latch piece configured for engaging with the power supply to block the power supply from moving in a direction perpendicular to the rear plate. The latch piece is resiliently deformable for disengaging the blocking portion from the power supply.

Abstract: A pen with adjustable holding structure is essentially for the user to write with his/her specified finger to lean against a stop protuberance. The pen has a penholder with a writing end formed at its front tip for writing. The stop protuberance is provided ahead of the holding position, and an adjustable holding part is formed on the penholder behind the stop protuberance. With this structure, when manipulating the pen, the user may select one of five fingers as a specified one to lean against the stop protuberance to settle thereat. The adjustable holding part is bendable at random according to the user's manipulation habit so as to lead the specified finger to lean against the best position on the stop protuberance to perform writing with the pen.
