On portions of the first and second positioning members 143, 153, close to the screw nuts, are disposed non-circular first and second engaging parts (unnumbered) corresponding to the engaging holes respectively. Another ends of the positioning members 143, 153 pierce out of the positioning holes to mount adjusting nuts 16, such that the fastening strength of two adjacent adjusting members is adjustable by screw the adjusting nut 16. Between the adjacent adjusting members is disposed a spring 17, thereby when the adjacent tooth plates are disengaged from each other, the spring 17 urges the adjusting members apart so as to facilitate the users to rotate the joint assembly.
Furthermore, the mounting unit 20 includes a socket 21, an arc-shaped urging body 22, a ball member 23, a sleeve 24, a jostle member 25 and a positioning bolt (not shown). The socket 21 axially extends from the top end of the first inner tube 111. Between two ends of the socket 21 is a positioning groove 211, and on a top surface thereof is a concave groove 212. In addition, the urging body 22 is disposed in the positioning groove 211 and has an outer arc surface 221. On the outer arc surface 221 is disposed a tapered groove 222 and a positioning notch 223 penetrating the urging body 22. The ball member 23 is disposed on the concave groove 212. A depth and a bore diameter of the concave groove 212 are smaller than a diameter of the ball member 23. On a top of the ball member 23 is extended a mounting pillar 231 to combine with a securing mount 5. Moreover, the sleeve 24 covers the ball member 23 and the socket 21. The sleeve 24 defines a receiving hole 241 axially penetrating the sleeve 24. A bore diameter of a top end of the receiving hole 241 is bigger than a diameter of the mounting pillar 231 and smaller than a diameter of the ball member 23. An inner surface of a top portion of the sleeve 24 is formed in an arc shape corresponding to a periphery of the ball member 23. On the bottom portion of the sleeve 24 is disposed a first threaded hole 242 corresponding to the tapered groove 222 and a second threaded hole corresponding to the positioning notch 223. The mounting pillar 231 pierces upward out of the receiving hole 241. A jostle member 25 includes a second screw 251 and a handle 252 disposed on one end of the second screw 251. On another end of the second screw 251 is a tapered jostle end 253 (as shown in FIG. 5). The positioning bolt is screwed through the second threaded hole and into the positioning notch 223.
Please refer to FIG. 5. The second screw 251 is screwed through the first threaded hole 242, and the tapered jostle end 253 is installed in the tapered groove 222. A center of the first threaded hole 242 is higher than that of the tapered groove 222, and an upper surface of the tapered groove 222 is located between the center and a top end of the first threaded hole 242. Therefore, the jostle member 25 moves downward along the tapered surface of the tapered groove 222 when it is screwed into the first threaded hole 242, thereby the sleeve 24 is guided downward as well, fastening the ball member 23 between the sleeve 24 and the concave groove 212 of the socket 21. In addition, the positioning notch 223 is extended upward from a bottom surface of the urging body 22, and the positioning bolt protrudes through the positioning notch 223 as well as the second threaded hole. Therefore, the urging body 22 will not rotate with respect to the sleeve 24, nor will the sleeve 24 escape upward from the engagement with the socket 21, yet the urging body 22 still has the ability to relatively move upward with respect to the positioning bolt to urge the socket 21 to position the ball member 23. Moreover, when the jostle member 25 is loosened, the ball member 23 can rotate within the space defined by the sleeve 24 and the top portion of the socket 21, and therefore the securing mount 5 can be adjusted universally. On the top portion of the sleeve 24 close to the receiving hole 241 is disposed a pair of vertical notches 243 in particular, while a breadth of each vertical notch 243 is slightly bigger than the diameter of the mounting pillar 231 so as to securely receive the mounting pillar 231 therein.
Now please refer to FIG. 6. The universal support of the present invention is provided with two joint assemblies 14, 15, so that it can be adjusted to the most desired and comfortable angle for the users to utilize. In addition, the universal support of the present invention is further provided with a mounting unit 20, while the ball member 23 can rotate between the sleeve 24 and the socket 21 by simply loosening the jostle member 25, such that the securing mount 5 along with the laptop computer 6 attached thereon can be positioned at any desired angle. Whats more, the universal support is also provided with a connecting unit 30, thereby it is fastened securely to a stationary object such as a base of a vehicle seat. Or, the connecting unit 30 can also be fastened to a wall as shown in FIG. 7A. Still, the shape of the connecting plate 32 is very possible to be varied into any shape as long as it can be installed onto a stationary object with a different installation angle as shown in FIG. 7B.
