ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of The Invention
The present invention relates to a handle tool used for a ZIF socket and an assembly comprising the handle tool and the ZIF socket, and especially to a handle tool which is suitable to manipulate a ZIF socket between a tightened status or a released status.
2. The Prior Art
Conventional ZIF sockets are usually installed with an actuation mechanism including a cam and a handle connected to the cam for controlling the cam to rotate clockwise or counterclockwise so as to manipulate the ZIF socket between a loosened status and a tightened status for assisting in the mounting of a CPU chip thereon. However, the actuation mechanism occupies too much space on the ZIF socket. Therefore, it is requisite to provide a new tool which can manipulate the status of the ZIF socket and conserve space thereon.
SUMMARY OF THE INVENTION
The primary purpose of the present invention is to provide a handle tool which decreases the thickness of a ZIF socket.
A second purpose of the present invention is to provide a handle tool for conveniently operating a ZIF socket between a loosened status and a tightened status.
In accordance with one aspect of the present invention, a handle tool is used with a ZIF socket which has a square cover matingly fixed on a bottom. The cover has a first diagonal line coplanar with a second diagonal line of the bottom. Both the first diagonal line and the second diagonal line are defined in respective surfaces of the cover and the bottom parallel to each other. The coplane of the first diagonal line and the second diagonal line is a virtual plane perpendicular to both surfaces of the cover and the bottom. The cover has a longer diagonal length than the diagonal length of the bottom, and is slidable with respect to the bottom along the second diagonal line. The handle tool comprises a scissors mechanism including a first lever arm pivotably connected to a second lever arm. The first lever arm defines a hole near a free end thereof for extension of a corner of the cover when an opposite corner of the cover is driven by a corresponding free end of the second lever arm upon a pivotable movement of the scissors mechanism.
In accordance with a second aspect of the present invention, a handle tool used for a ZIF socket having a cover slidably fixed on a bottom wherein the cover has two protrusions projecting from two opposite sides thereof. The cover is slidable over the bottom along a line defined between the two protrusions. The handle tool comprises a scissors mechanism including a first lever arm pivotably connected to a second lever arm. The first lever arm defines a hole near a free end thereof for extension of one of the protrusions of the cover therethrough when the opposite protrusion is driven by a corresponding free end of the second lever arm upon a pivotable movement of the scissors mechanism.
In accordance with a third aspect of the present invention, a handle tool comprises a scissors mechanism including a first lever arm pivotably connected to a second lever arm. The first lever arm defines a hole near a lower free end thereof for extension of a portion of a cover of a ZIF socket therethrough which is slidably mounted on a corresponding bottom of the ZIF socket when the scissors mechanism is operated to cause the lower end of the first lever arm and a confronting lower free end of the second lever arm to move toward each other thereby moving the cover along the bottom of the ZIF socket.
In accordance with a fourth aspect of the present invention, a handle tool comprises a scissors mechanism including a first lever arm pivotably connected to a second lever arm. The second lever arm forms a protrusion near a lower free end thereof for encountering a portion of a bottom of a ZIF socket on which a cover sized to be greater than the bottom is slidably mounted. The scissors mechanism is operated to cause the lower end of the first lever arm and the corresponding protrusion of the lower free end of the second lever arm to move toward each other thereby moving the cover along the bottom of the ZIF socket.
In accordance with a fifth aspect of the present invention, a handle tool comprises a scissors mechanism including a first lever arm pivotably connected to a second lever arm. The first and second lever arms respectively form first and second protrusions near a lower end thereof for respectively encountering a cover and a bottom of a ZIF socket which are slidably engaged. The scissors mechanism is operated to cause the first and second protrusions to move toward each other thereby moving the cover along the bottom of the ZIF socket.
