The present embodiment is a kind of twin shaft Universal-head, sees shown in Fig. 1 to Fig. 6, comprises base 1, Connection Block 2, backing roll 3 and driving mechanism 4.

As shown in Figure 6, be provided with circular orbit 11 in base, the cross sectional shape of this circular orbit is " convex shape ", and the center of this circular orbit is provided with the round boss 13 that projects upwards formation.

See shown in Fig. 1, Fig. 3 and Fig. 4, the roof of backing roll is provided with three straight line mounting rails 31, the shape of backing roll diapire is semicircle arcuation, backing roll diapire is provided with and is combined to form multiple teeth groove 33 of half gear 32, two indent arc-shaped guide rails 34 that are positioned at teeth groove both sides and the auxiliary rail 35 of two evaginations, auxiliary rail is positioned at the both sides of teeth groove, and within being positioned at two arc-shaped guide rails.The cross sectional shape of this arc-shaped guide rail 34 is " convex shapes ".

The diapire of Connection Block is provided with two guiding slide units 21 that give prominence to and circular orbit adaptation base downwards, in the centre of two guiding slide units, is also provided with the circle of round boss 13 adaptations and slips groove 20, and round boss 13 is arranged in circle and slips groove 20.Connection Block can circle along the circular orbit of base under the guide effect of guiding slide unit, is also that Connection Block line centered by the central axis of round boss 13 moves in a circle.

The top of Connection Block is provided with the circular arc support plate 22 with backing roll diapire adaptation, the middle part of Connection Block is provided with rotating shaft installing hole 23, the roof of support plate be provided with the driving mouth 24 that is communicated with rotating shaft installing hole, indent two respectively with the auxiliary stopper slot 26 of a corresponding auxiliary rail adaptation, be positioned at drive mouthful both sides respectively with the guide pad 25 of a corresponding arc-shaped guide rail adaptation; Assist stopper slot between guide pad, and be positioned at driving mouthful both sides; The quantity of guide pad comes to four, and every two guide pads are arranged on same circular arc line, and with corresponding same arc-shaped rail 34 adaptations, be also in same arc-shaped rail, be provided with two guide pads.The cross sectional shape of auxiliary rail and auxiliary stopper slot is all rectangles.

Driving mechanism comprises rocking handle 5, rotating shaft 6 and keeper 7; Keeper is provided with axis hole 71, and is fixedly installed on rotating shaft installing hole opening part by four attachment bolts 72; The medial extremity of rotating shaft is arranged in rotating shaft installing hole, rotating shaft be provided with annular with the external screw thread drive division 61 of above-mentioned half gear adaptation, the part body of this external screw thread drive division exposes the driving mouth of support plate and is meshed with half gear of backing roll, the outboard end of rotating shaft stretches out the axis hole of keeper, and rocking handle is fixedly installed on the outboard end of rotating shaft; When rocking handle drives rotating shaft to rotate, the external screw thread drive division of rotating shaft drives half gear, and the setting party along arc-shaped guide rail 34 moves to driving backing roll to do circular arc line under the guide and limit effect of guide pad 25 and auxiliary stopper slot 26.
