A safety structure of a desk-top Liquid Crystal Display (LCD) is disclosed. The safety structure has a seat body pivotally mounted to a monitor, characterized in that the monitor is provided with two sections of elevation angle, wherein the first section of the elevation angle complies with the angle of application for human body, and the second section of the elevation angle has a maximum elevation angle in parallel to a base seat of the monitor, and the twisting force of the monitor required to rotate within the scope of elevation angle of the second section is larger than that of the elevation angle of the first section, but the twisting force to rotate within the second section is smaller than the weight of the seat body.

1. A safety structure of a desk-top Liquid Crystal Display (LCD) having a seat body pivotally mounted to a monitor and the pivoting device being a securing frame having two sides mounted corresponding with a chain, wherein the securing frame is fixed to the monitor and the two lateral sides of the securing frame are each provided with a protruded lug having provided with pivotal hole, and one side of the pivotal hole is provided with a limiting hole and the peripheral edge of the protruded lug is provided with a positioning notch; the chain includes a rotating shaft, a first section limiting plate, a second section limiting plate, a securing plate, a plurality of elastic pads, a plurality of damping plates, a top pressing pad, and a securing nuts, wherein the rotating shaft includes a combining section for mounting onto the seat body, and the upper section of a pivotal shaft is an engaging flat section and in turn passes through the first section limiting plate, a damping pad, a second section limiting plate, a damping pad, a pivotal hole on the protruded lug, a damping pad and a securing plate, and a threaded shaft is provided at one lateral side of the pivotal shaft, and in sequence, mounted with two elastic pads, a top pressing pad, and a securing nut; the first section limiting plate is mounted the pivotal shaft and is rotatable thereon and at one lateral side of the plate has a first limiting arm, the first limiting arm is extended through the limiting hole of the protruded lug; the second section limiting plate is fixed at the pivotal shaft and is rotatable thereon and one lateral side of the plate has a second limiting arm and the second limiting arm is extended to the positioning notch at the circumferential edge of the protruded lug; the securing plate is mounted onto the pivotal shaft and is rotatable thereon, and one lateral side is provided with an engaging slot for the passing through of the first limiting arm of the limiting hole for mourning; the elastic pad is mounted onto the threaded shaft rod section of the pivotal shaft; a plurality of damping pads are respectively between the first limiting plate and the second limiting plate, the second limiting plate and the protruded lug, the protruded lug and the securing plate; the top pressing pad is located at the external side of the elastic plate; and the securing nut is screwed to the threaded shaft rod.2. The safety structure of claim 1, wherein the limiting hole is an arch-shaped hole and the positioning notch is an arch-shaped notch and the arch length of the positioning notch is larger than the limiting hole.3. The safety structure of claim 1, wherein the monitor is provided with a first section and second section elevation/inclination angle by means of the limiting hole and the first limiting arm in association with the positioning notch and the combination of the second arm position.4. The safety structure of claim 3, wherein the scope of the first section elevation/inclination angle is 5 to 20 degree and the scope of the second section elevation/inclination angle is 20 to 90 degree.5. The safety structure of claim 3, wherein the twisting force needed to rotate within the range of the second section angle is larger than that of the second section angle, but is smaller than the weight of the seat body.6. The safety structure of claim 1, wherein the pivotal device includes two separate fixing frames, each having a chain.7. A safety structure of a desk-top Liquid Crystal Display (LCD) having a seat body pivotally mounted to a monitor, characterized in that the monitor is provided with two sections of elevation angle, wherein the first section of the elevation angle complies with the angle of application for human body, and the second section of the elevation angle has a maximum elevation angle in parallel to a base seat of the monitor, and the twisting force of the monitor required to rotate within the scope of elevation angle of the second section is larger than that of the elevation angle of the first section, but the twisting force to rotate within the second section is smaller than the weight of the seat body, wherein the first section elevation angle is 5 degree of inclination to 20 degree of elevation angle, and the twisting force for rotation is about 11 to 16 kg/cm, and the second section elevation angle is inclination angle of 20 degree and the elevation angle of 90 degree, and the twisting force for rotation is about 45 to 55 kg/cm.
