DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to FIGS. 1, 2 and 5, a pivotal shaft assembly according to the present invention includes a bottom plate 1, a fixing member 2, a rotational member 3, a spherical nest device 4 and a connecting plate 5. Wherein, the bottom plate 1 is flat with a plurality of plate holes or plate grooves 11 for being passed through with screws and fastened to a stationary article such as a wall. The bottom plate 1 at the center thereof is provided with at least a through hole 12 for being passed with a screw 13 so as to be fastened to a preset threaded hole 22 at the bottom of the fixing member 2. In addition, a plurality of locating holes 14 are provided near the through hole 12 for being inserted with locating tenons 23 at the bottom of the fixing member 2. The fixing member 2 at the bottom thereof has a support base 21 with the threaded hole 22 and the locating tenons 23 corresponding to the through hole 12 and the locating holes 14 so that the fixing member 2 can be joined to the bottom plate 1 firmly by way of the screw 13 passing through the holes 12, 22 and the locating tenons 23 fitting with the locating holes 14. Because these are conventional art, no details will be described further. Besides, the support base 21 at the front side thereof integrally connects a joint seat 24 and it is preferable that the joint seat 24 is cylindrical with a central shaft groove 241. The rotational member 3 is a U-shaped frame with two lateral sides thereof extending outward a wing plate 31 corresponding to the size of the joint seat 24 and the inner sides thereof next to a packing ring 32 respectively so that the joint seat 24 can be just received in a space between the packing rings 32 with the shaft groove 241 being opposite to a central engaging hole 311 of the respective wing plate 31. Once, an axial bolt 33 is inserted into one of the wing plate 31 via the engaging hole 311 thereof and passes over the shaft groove 241, the axial bolt 33 at the free end 331 thereof is received in the engaging hole 311 of another wing plate 31 with a bolt head 332 at the lower end thereof being held by a holding part 312 (not shown in FIG. 2) at the second wing plate 31. For instance, the bolt head 332 has at least a flat edge 333 engaging with a stopper extending from the wing plate 31 to form a state of firm joint. Afterward, a threaded fastener 34 such as a screw engages with the free end 311 to allow the two wing plates 31 and a threaded hole 334 of the packing ring 311 gradually clamping two lateral sides of the joint seat 24 commonly so as to constitute frictional torque. Further, the rotational member 3 at the front side thereof is provided with a connecting hole 35 for the spherical nest device 4 being able to be held at said front side. Further, in order to let the two packing disks 32 being located between the wing plates 31, there are a plurality of projections 321 disposed at the outer side of the respective packing disk 32 and it is preferable that three projections 321 are provided to insert into fitting holes 312 near the rim of the respective wing plate 31. Besides, each wing plate 31 at the outer side thereof is attached with a decoration cover 36 and a plurality of cover projections 361 are disposed at the inner side of the decoration cover 36. It is preferable that three pieces of cover projections 361 are provided for being inserted into further fitting holes 312 other than those fitting with the projections 321 so as to hide the threaded fastener 34 and the bolt head 332. In addition, the present invention further includes a wire arranging device 37, which is composed of a pair of opposite engaging part 371 extending outward from the circumference of one of the packing disks 32 and an engaging ring 372 at two ends thereof engaging with the engaging parts 371 to form an enclosing space, and the lead wires can passed through the enclosing space without being out of order. The spherical nest device 4 has a connecting stem 41 and an extension rod 411 extends from an end of the connecting stem 41 to pass through both of a spherical durable ring 42 and a blocking lid 43 and to fit with the connecting hole 35 with a joining piece 44 such as a screw for engaging with a rod hole 412 so as to form a state of being located. A positioning ball 412 is disposed at the front end of the extension rod 411 and at the front side of the positioning ball 412 is enclosed by another spherical durable ring 42 and presses against a circular recess part 441 at the center of a front cover 44. In the meantime, screws 431 pass through at least three through holes 432 preset at the lid 43 and are fastened to joining holes 442 at the rim of the circular recess part 441. In this way, the positioning ball 413 can generate frictional torque by way of the two durable rings 42 approaching each other gradually to provide a function of directional adjustment. Besides, the front cover 44 at the upper rim thereof extends outward an engaging plate 443 and at the bottom thereof has a piercing hole 444 at two opposite sides respectively. The connecting plate 5 at the periphery thereof has plate holes 51 for being passed through with screws and fastened to a plane display and at the rear side thereof is provided with an upper lap part 52 for engaging with the engaging plate 443. Two engaging holes 53 are aligned with the piercing holes 444 and each engaging hole 53 is fastened with a hand knob bolt 445 via the corresponding piercing hole 444 respectively. Hence, the plane display can be mounted to the front side of the pivotal shaft assembly. Referring to FIGS. 3 and 4, another embodiment of the spherical nest device 4 is illustrated. The difference of the present embodiment from the preceding embodiment is in that the blocking lid 43 at the circumferential edge thereof is provided with outer threads 433 and at the rear side thereof is provided with a plurality of operational holes 434, which are spaced apart from each other with an equal circular distance. The front cover 44 is provided with inner threads 446 corresponding to the outer threads 433. A fixture can be inserted into any two opposite ones of the operational holes 434 to turn the blocking lid 43 in a way of the outer threads 433 engaging with the inner threads 446 such that the positioning ball 413 can be covered completely by the two packing disks 42 to prevent from eccentric movement resulting from uneven frictional torque. It is appreciated that while the pivotal shaft assembly for a plane display according to the present invention is in use, it is only necessary to turn the threaded fastener so as to allow the axial bolt generating a relative motion such that the two oppositely disposed wing plates and packing disks can be pressed or released respectively for adjusting the torque value to avoid torque offset resulting from bi-directional adjustments. Besides, the spherical nest device can provide a better frictional torque and adjust the torque value by way of two different lids and the front cover so that the phenomenon of offset is resisted during multi-directional adjustments being executed. In addition, a retaining ring type of wire arrangement device is mounted in the pivotal shaft assembly of the present invention for the lead wires and signal wires not tangling to each other. Furthermore, it is possible for the user to join the front cover and the connecting plate quickly with the elongated hand knob bolt instead of hand tool, which is hard to perform the joining job due to being blocked by the lid. While the invention has been described with reference to the preferred embodiments thereof, it is to be understood that modifications or variations may be easily made without departing from the spirit of this invention, which is defined by the appended claims.
