Abstract
A fixing device for a pen clip which contains a fixing cap, an upper casing, a fixing clip, an adjusting assembly and a lower casing. The upper casing is a hollow tube and has a trumpet-shaped mouthpiece (top wide while bottom narrow) for receiving the fixing cap in place. The fixing cap has an indentation to receive the fixing clip. A screw is tightened from the inner side of the adjusting assembly to the fixing cap. The trumpet-shaped mouthpiece of the upper casing will be expanded by the screw for a tight connection with the fixing clip so that the fixing clip is situated between the casing and the fixing cap and won't be easily disconnected. Accordingly, an additional fixing effect and a convenient application is achieved.
Claims7
A fixing device for a pen clip comprising:
- a fixing cap having an inclined guiding surface and a flange at the top thereof, an indentation vertically extending along the side of said fixing cap and being disposed at a rim of said inclined guiding surface;
- an upper casing being a hollow tube one end of which is wide at the top and narrow at the bottom thereof;
- a fixing clip being bent and made by a metal piece and having a connecting part at one end thereof and another end;
- an adjusting assembly having a female-threaded hole at one end thereof and a flange at the other end thereof;
- and
- a lower casing having a conic hollow end while the other end thereof is secured with a fixing seat in such a way that an ink cartridge is only movable in a preset position;
- wherein respective ends of said fixing cap and said adjusting assembly are threadedly tightly fastened to one another by a screw at an end of said upper casing, and
- wherein, due to a curved design of said fixing clip, the clearance between both ends of said fixing clip is smaller than the diameter of said upper casing so that, when said flange of said fixing cap is engaged against a trumpet-shaped mouthpiece of said upper casing, said connecting part of said fixing clip is tightly received in said indentation while the another end of said fixing clip leans tightly against an outer side of said upper casing to create an opposite clamping force so said fixing clip will not be easily disconnected, and
- said upper casing is expanded by the screw for a tight connection with the fixing clip and therefore cannot be easily disconnected after a long period of use.
