ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a tool suspension device, and more particularly a tool suspension device that holds a tool and provides security and anti-thief features when displaying a tool with a tool head.
2. Description of Related Art
With reference to
FIG. 15
, a conventional tool suspension device in accordance with the prior art is composed of a back-plate (
50
) and a tool bracket (
60
) attached to the back-plate (
50
).
The back-plate (
50
) is rectangular and has a bottom edge, a top edge and two side edges. Two mortises (
51
) are respectively defined near the bottom edge and opposite side edges of the back-plate (
50
). A through hole (
52
) is defined in the back-plate (
50
) between each mortise (
51
) and the corresponding side edge.
The tool bracket (
60
) is substantially U-shaped with a receiving space (
61
) to hold a tool (not shown) and has two sides. An ear (
62
) is formed at each side of the receiving space (
61
). Each ear (
62
) has a face (not numbered) to abut the back-plate (
50
) and a lipped protrusion (
64
) formed on the face to engage the corresponding mortise (
51
) to attach the tool bracket (
60
) to the back-plate (
50
) to suspend a tool between the back-plate (
50
) and the tool bracket (
60
). A through hole (
65
) is defined in each ear (
62
) near the lipped protrusion (
64
) to align with the corresponding through hole (
52
) in the back-plate (
50
). A plug (
63
) with a shaft and two ends has a head (not numbered) on one end and a lip (not numbered) on the other end. The shaft is partially split longitudinally so the lip and the shaft can be pressed through the through hole (
65
) in the ear (
62
) and the through hole in the back-plate (
52
) and provide an anti-thief feature.
However, the conventional tool suspension device still has the following drawbacks:
1. The lipped protrusion (
64
) on the tool bracket (
60
) detachably engages the mortise (
51
) in the back-plate (
50
) to hold the tool on the tool suspension device. However, the lipped protrusion (
64
) is easily broken when the tool bracket (
60
) detaches from the back-plate (
50
) several times or when the tool bracket (
60
) holds a heavy tool. Therefore, the conventional suspension device is not durable.
2. When using the lipped protrusion (
64
) and the mortise (
52
) to mount the tool, the conventional suspension device further needs the plug (
63
) to achieve the anti-thief effect. Therefore, manufacturers need two attachment processes to assemble the conventional tool suspension device, and that makes the assembly of the conventional tool suspension device unnecessarily time-consuming and troublesome. Furthermore, production cost of the conventional tool suspension device is also raised.
To eliminate the foregoing disadvantages of the conventional tool suspension device, the present invention provides a tool suspension device that is conveniently assembled, which stably holds a tool on the tool suspension device.
SUMMARY OF THE INVENTION
A first objective of the invention is to provide a tool suspension device that is convenient to assemble or disassemble.
A second objective of the invention is to provide a tool suspension device that holds a tool stably.
