• both parts of the body 61, 62 of the actuation and blocking group of the joint 27 comprise radial extensions in the form of flanges 73 and 74 which are arranged in abutment below the base 12 or above the top 13 in an operative position.
• At least one of the two radial flanged extensions 73 comprises a pass-through seat 75 for receiving a fixing screw 76 of the actuation and blocking group of the joint 27, once inserted in the hole 22 of the base 12 or top 13.
• a transmission and actuation rod 77 is in fact first included for transmitting rotation on the rear joint G'. It can be noted that said transmission and actuation rod 77, at one of its ends, penetrates the pass-through hole 69 so as to be engaged in the actuation seat 29 of the pinion 28 of the rear j oint G ' .
• a further shorter transmission and actuation rod 77' can also be included, which is inserted into the pass-through hole 69 of the front joint G so as to be engaged in the actuation seat 29 of the pinion 28 of the front joint G itself.
• a bracket 78 can be included, provided with elastic supports 79, C-shaped and open towards the bottom, which house, free to rotate, both of said transmission and actuation rods 77, 77' facilitating their actuation.
• the bracket 78 can be fixed to the base or bottom 12 or to the top 13 by means of screws 80.
• Said pin 17 comprises a pair of half-shells 81, 82 having a hemi-cylindrical form, suitable for being housed in the hole 23, when joined together to form a casing.
• the half shells 81, 82 of the casing are partially hollow and house, free to rotate, a stem 83 terminating on one side in the threaded end 16.
• a toothed crown 84, formed as head of the stem 83, is integral with the other end of the stem 83, which engages with a pinion 85.

• the pin 17 therefore also comprises a kinematic actuation mechanism for rotating the threaded end 16.
• Said shaped end 30b of the stem 30 is in fact inserted in the shaped hole or seat 31 formed in the above-mentioned pinion 85 of this further bevel gear arranged inside the pin 17.
• FIG. 5 shows what has just been described and figures 16 to 25c show this first embodiment of the pin 17 in detail.
• the stem 83 is housed on supporting seats 86 inside the two half-shells 81, 82 and also a pin 87 of the pinion 85 finds is housed rotating in a seat 88 of the half-shell 81.
• the two half-shells 81,82 are joined by centering plugs 89 of a half-shell 82 which are arranged and housed in pass through holes 90 and are riveted in 91 to block the parts together .

• pin 17 can be in a second embodiment illustrated in figures 26 to 35c with a retractable threaded end 16 as can be seen hereunder.
• the pinion 85 is positioned as in the first example, whereas the toothed crown 84 is arranged at one end of a stem 92 internally provided with a cavity 93.
• An end of a rod 94 is free to slide in the cavity 93, which, in an intermediate portion, provides a radial flange 95 projecting outwardly.
• the other end of the rod 94 is threaded in 16 as in the previous example.
• a compression spring 96 is arranged between the radial flange 95 and the end of the stem 92, which, in rest position, keeps the threaded end 16 of the rod 94 protruding from the half-shells 81, 82.
• the flange 95 also acts as a contrast to the extension of the spring 96 as it is abutted against stops 97 formed in the internal cavities of the half-shells 81, 82.
• both the joining pin 17 and the actuation and blocking group 27 of the joint G,G' can be immediately positioned.
• Figures 2 to 5 show these operations as they are effected.
• Both the pin 17 and the actuation and blocking group 27 are in fact prepared.
• the pin 17 is inserted in the relative hole 23 so that the hollow grooves 72 formed externally to the body of the pin 17 are on the sides of the same inside the hole 22, as shown in figures 3 and 3b.
