Abstract

The present disclosure illustrates a fixing device comprising a sleeve which has a through hole inside and has grooves recessed on an outer surface thereof, and is placed inside receiving space of an outer casting tube, and the receiving space being formed with longitudinal protrusion rib disposed on an inside wall thereof and slidable in the grooves, and a head part is disposed inside the receiving space and has a mounting; a resilient component is abutted between the head part and the sleeve; a fastener fixed on the head part and having a riveting part mounted in the mounting hole, and a rod extended from a bottom thereof and inserted through the through hole, and having longitudinal sections and arc surfaces and the rod having a stop part outwardly protruded on a bottom side thereof, and having a guiding incline formed at top thereof.

First claim

What is claimed is:

1. A fixing device comprising a fixing assembly, a first plate and a second plate, wherein:
the fixing assembly comprises a sleeve, an outer casting tube, a head part, a resilient component and a fastener, said sleeve has a through hole inside and cut therethrough, and has a plurality of grooves recessed on an outer surface thereof and arranged with equal interval, and a positioning part disposed on a bottom side thereof, and wherein said outer casting tube is disposed at a top of said sleeve and has a receiving space inside for insertion of said sleeve, and said receiving space is formed with at least one longitudinal protrusion rib disposed on an inside wall thereof and slidable in the plurality of grooves, and wherein said head part is disposed inside the receiving space of said outer casting tube and has a mounting hole formed at a central part thereof and cut therethrough, and said resilient component is abutted between said head part and said sleeve, and said fastener is disposed under said sleeve, inserted into said through hole and fixed on said head part, and said fastener has a riveting part mounted in said mounting hole, and a rod extended from a bottom thereof and inserted through said through hole, and wherein said rod has longitudinal sections formed on two opposite sides of the outer surface thereof and cut therethrough, and said fastener has arc surfaces formed on other two opposite sides of the outer surface thereof, and said rod has a stop part outwardly protruded on a bottom side thereof, and said stop part has a guiding incline formed at a top thereof;
wherein said first plate has a hole for fixation of said positioning part of said sleeve; and
wherein said second plate is placed in parallel to said first plate and has a cut groove cut through and having a tapered shape from outside of a side of said second plate for insertion of said fastener, and said cut groove has a narrow portion formed at an end thereof and configured to be blocked by said arc surfaces for rotation of said outer casting tube, and said narrow portion has a fastening hole extended from a side thereof and configured for insertion of said rod, and said fastening hole has a gradually-extended incline formed on a sidewall thereof remote from said first plate and configured for return of said stop part, and said second plate has a supporting surface formed on ends of two side surfaces of said cut groove and tapered outwardly, and configured to push said guiding incline of said stop part to extend said rod out of said through hole of said sleeve.

2. The fixing device according to claim 1 , wherein said through hole of said sleeve has a receiving groove formed at the top thereof and having an extended hole diameter, and configured to abut with an end of said resilient component.

3. The fixing device according to claim 1 , wherein said positioning part of said sleeve has an annular trench disposed on an outer surface thereof.

4. The fixing device according to claim 1 , wherein the receiving space of said outer casting tube is formed with a mounting hole disposed on an upper part thereof and having a tapered hole diameter, and the receiving space is formed with an annular mounting groove recessed on an inside wall thereof adjacent to said mounting hole, and said outer casting tube has a pulling member outwardly formed on a surface thereof, and said head part has a base portion protruded on a top thereof and configured to be mounted in said mounting hole, said base portion has a locking protrusion ring form on a peripheral edge outwardly and configured to be mounted in said mounting groove, and said locking protrusion ring has an engaging surface formed with tooth-shaped structures, and said base portion has a protrusion formed at a bottom thereof and located at peripheral edge of said mounting hole, and configured to be mounted with said resilient component.

5. The fixing device according to claim 4 , wherein said pulling member has at least one pulling member or pull-tab.

6. The fixing device according to claim 1 , wherein said stop part of said fastener has at least one section formed on an outer surface thereof and being parallel or perpendicular to said longitudinal sections.

7. The fixing device according to claim 1 , wherein a contained angle between said guiding incline of said stop part and the bottom surface of said stop part is ranged between 60 degrees and 120 degrees.

8. The fixing device according to claim 1 , wherein an interval of said narrow portion of said cut groove of said second plate is equal to or greater than an interval of said two longitudinal sections of said rod, and smaller than an interval of said two arc surfaces.

9. The fixing device according to claim 1 , wherein said fastening hole of said second plate has an outer diameter equal to or greater than an outer diameter of said rod, and said gradually-extended incline of said fastening hole has an inclination equal to that of said guiding incline of said stop part.

10. A fixing device, comprising a fixing assembly which comprises a sleeve, an outer casting tube, a head part, a resilient component and a fastener, wherein:
said sleeve has a through hole inside and cut therethrough, and a plurality of grooves recessed on an outer surface thereof and arranged with equal interval, and said sleeve has a positioning part disposed at a bottom side thereof;
wherein said outer casting tube is disposed over said sleeve, and has receiving space inside for insertion of said sleeve, and the receiving space is formed with at least one longitudinal protrusion rib disposed on an inside wall thereof and slidable in said plurality of grooves;
wherein said head part is disposed in the receiving space of said outer casting tube, and has a mounting hole formed at a central part thereof and cut therethrough;
wherein said resilient component is abutted between said head part and said sleeve;
wherein said fastener is disposed under said sleeve and inserted into said through hole, and fixed on said head part, and said fastener has a riveting part configured to be fixed in said mounting hole, and said riveting part has a rod extended from a bottom thereof and configured to be inserted into said through hole, and said rod has longitudinal sections formed on two opposite sides of an outer surface thereof and cut therethrough, and arc surfaces formed on two sides of the outer surface thereof other than said longitudinal sections, and said rod has a stop part outwardly protruded on a bottom side thereof, and said stop part has a guiding incline formed on a top thereof, and a second plate abut against the guiding incline, to drive the rod to move out of the through hole of the sleeve.
