ABSTRACT:
FIELD OF THE INVENTION
The present invention relates generally to a cooling piece, and more particularly to a device for retaining the cooling piece.
BACKGROUND OF THE INVENTION
As shown in
FIG. 1
, the prior art device
80
mainly embraces a central portion acting as a pressing portion
82
, on both ends of the pressing portion, two tilt extensions constitute two elastic portions
83
. The end of the elastic portion
83
drops downward to become a buckle leg
84
. Each buckle leg
84
has a perforated hole
85
. A central part of one buckle leg
84
stretches outward and upward to form a hook blade
86
. As shown in
FIG. 2
, the device
80
holds the cooling piece
90
with the perforated hole
85
of one buckle leg
84
grasp the end jaw
97
of CPU socket
95
. Then holding a cabinet tip of a screwdriver
99
at the mid-way between the perforated hole
85
and the buckle leg
84
, forcing the buckle leg
84
to move inward in such way as to push the perforated hole
85
entering into the jaw
97
of the CPU socket
95
so the cooling piece
90
will intimately attached to the CPU
94
.
However, in the normal assembly operation, if the screwdriver
99
, being too small in size, can be easily clamped between the hook blade
86
and the buckle leg
84
, very hard for the operator to pull off. If the screwdriver
99
is too large, when the force is improperly applied, it might easily skid out of the hook blade
86
. If the force applied is too powerful, it might produce severe damage to the parts on the main board
100
. In case the operator's hand hits the cooling piece
90
, it results in a critical injury, cut or incident.
SUMMARY OF THE INVENTION
It is therefore the primary objective of the present invention to provide a device for retaining a cooling piece. The retaining device can be easily mounted and dismounted.
It is another objective of the present invention to provide a device for retaining a cooling piece. The retaining device prevents the screwdriver from being clamped in the process of operation.
It is still another objective of the present invention to provide a device for retaining a cooling piece. The retaining device prevents the screwdriver from skidding off and averts the incident injury and cut to the operator.
In keeping with the principle of the present invention, the foregoing objective of the present invention is attained by a retaining device comprising a main body provided with a press portion having elastic portions on both sides of the press portion, leg portion with a retaining portion extending down from the ends of the elastic portions; one leg portion stretches inward and upward to form a hook, and the leg portion has an operation hole located on the upside of the hook.
The foregoing objectives, features, functions and advantages of the present invention will be more readily understood upon a thoughtful deliberation of the following detailed description of a preferred embodiment of the present invention with reference to the accompanying drawings.
