## Background
BACKGROUND OF THE INVENTION
1. Technical Field
The present invention relates to a positioning device that is configured to work with a fixer for handheld, portable, mobile devices to hold and suspend a mobile electronic device, such as a mobile phone, a portable game player, an electronic book, a GPS device or a tablet computer.
2. Description of Related Art
Recently, handheld, mobile devices such as mobile phones and tablet computers have been popular, and nowadays almost everyone has one. While these mobile devices are relatively compact and light-weight, holding them in hand for a sustained time period is still a significant, accumulative burden to muscle, and this is particularly true for people lacking exercise.
There are some fixers designed for small-size mobile devices, but these fixers commonly fail to provide the advantages desired by users, such as being easy to mount and dismount, being compact and light, and being retractable, thereby being more portable.
The existing fixing tools for mobile devices are mainly using a flexible hose ended with a clamp that is configured to hold the whole tool on a table plate. While such an existing fixing tool is effective in suspending a mobile device over a table, it is structurally weak and tends to deform and come down after a long term of suspension. Also due to its weakness, for operating the mobile device, a user has to first use one hand support the mobile device from its back and then use the other hand to touch the touch screen. Thus causes the existing fixing tools to be unfavorable to mobile device operation.
Moreover, in the existing fixing tool, the clamp can only work well with a planar support. However, when leaving a house and used in a public transportation vehicle, such as a MRT train, a subway or a bus, where there are only vertical mopstick handrails, the fixing tool fails because its clamp cannot engage with the handrails effectively. The above-mentioned problems are for us to solve.
BRIEF SUMMARY OF THE INVENTION
The present invention provides a portable positioning device that is configured to work with a fixer to hold and suspend a mobile electronic device, such as a mobile phone, a portable game player, an electronic book, a GPS device or a tablet computer. The primary objective of the present invention is to suspend a mobile device with proper overall rigidity, so that a user can operate the suspended mobile device by touching or sliding on its touch screen without displacing the mobile device from where it is positioned. Also, the disclosed fixer is configured to firmly grasp a smooth, vertical rod, so that a user riding a public transportation vehicle can conveniently suspend and use his/her mobile device in the vehicle, wherein the positioning device and the fixer supports the mobile device with proper overall rigidity, so that a user can operate the suspended mobile device by touching or sliding on its touch screen. Thereby, the present invention is helpful to prevent users' muscle fatigue and ache caused by overuse of neck and shoulder muscles.
To this end, the present invention provides a positioning device working with a fixer for handheld, portable, mobile devices, the positioning device comprising a securing member that is coupled to an external fixer, the fixer having a positioning frame for holding an external mobile device in position, and the positioning device being characterized in:
