DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0022] Referring to FIG. 1, a screen support frame comprises:

[0023] a screen support frame 1, wherein the screen support frame 1 comprises a base 11 and a supporting member 12, and, with reference being had to FIGS. 2 and 3, the supporting member 12 comprises a supporting member mounting portion 121 and a supporting member rotating portion 122, the supporting member mounting portion 121 having one end mounted to the base 11, the supporting member mounting portion 121 having an opposite end on which a protrusion 1211 and a rotation stop 1212 are formed, the supporting member rotating portion 122 comprising a receiving hole 1221 and a receptacle 1222 formed therein, wherein the protrusion 1211 of the supporting member mounting portion 121 is received and disposed in the receiving hole 1221 of the supporting member rotating portion 122, and the rotation stop 1212 of the supporting member mounting portion 121 is disposed in the receptacle 1222 of the supporting member rotating portion 122, so that the supporting member 12 may transmit an effect of rotation; with additional reference to FIGS. 4 and 5, the supporting member rotating portion 122 comprises a pair of rails 2, and a longitudinally movable member 3 is arranged between the rails 2, the longitudinally movable member 3 having a side surface from which a frontward projection arm 31 extends outward, the longitudinally movable member 3 having an opposite side that is provided with a friction member 32 and a plurality of elastic member receiving troughs 33, an enclosure 4 being provided to enclose the supporting member rotating portion 122, a plurality of elastic members 41 being arranged in an interior of the enclosure 4, the elastic members 41 being respectively disposed in the elastic member receiving troughs 33 of the longitudinally movable member 3 to each provide a spring force, the enclosure 4 comprising a friction track 42, the friction track 42 being provided for contact engagement with the friction member 32 of the longitudinally movable member 3 to increase a frictional force.

[0024] Preferably, the longitudinally movable member 3 is provided with a friction adjusting member 321. The friction adjusting member 321 is arranged to push against the friction member 32 to make adjustment of the frictional force between the friction member 32 and the friction track 42 for increasing or decreasing the frictional force.

[0025] Further referring to FIGS. 5 and 6, a screen fixing portion 5 is provided, and the screen fixing portion 5 is mounted to the frontward projection arm 31 of the longitudinally movable member 3 of the supporting member rotating portion 122. The screen fixing portion 5 is provided with a group of symmetrically arranged elastic members 51 and a group of symmetrically arranged friction members 52, wherein the symmetric elastic members 51 of the screen fixing portion 5 provide spring forces and the symmetric friction members 52 of the screen fixing portion 5 provide frictional forces, both combined providing the screen fixing portion 5 with an effect of adjusting an elevation angle of a screen attached thereto, as shown in FIG. 9.
