[Prior Art] According to a conventional hinge structure, as shown in Fig. 12, it includes a rotating device (80) and a fixing device (9), wherein the rotating device (80) includes a mandrel (81), a base (82) and a T-shaped column (83), the mandrel (81) is provided with a positioning surface (811) on the shaft body. The mandrel (81) is further extended to both ends. The pivoting portion (812) is provided with a pivot hole (821) through which the pivot hole (821) is pivoted, and the base (82) is disposed on one side. There is a set of joints (822) > the joints (822) are combined with a base (823), the set of joints (822) are provided through the receiving holes (824), and the receiving holes (824) are hinged The through holes (821) are connected to each other, the T-shaped column (83) is accommodated in the receiving hole (824) of the base (δ2), and the top type column (83) is provided with a top supporting surface (831) on one side, The top support surface (831) is abutting against the positioning surface (811) of the mandrel (81), and the other side is abutted with an elastic member (832), and the other end of the elastic member (832) is abutted against the base ( 823), the fixed skirt (9〇) contains two splints (91) (910), The splint (9) (910) is in the shape of a weir and a rotating space (911) is formed at the opening, wherein a splint (91) protrudes from the opening edge with a coupling rib (9) 2), the engaging rib ( 912) is combined with another-cool plate (91〇) 201245553. The combined rib (912) is recessed on both sides with a groove (913), and the engaging groove (913) is assembled. The pulling portion (812) of the mandrel (41); when the normal state is not actuated, the T-shaped column (83) is abutting against the positioning surface (8H) of the mandrel (81), so that the mandrel (81) is formed. Positioning state; when pushing the door body, the door body is rotated by the spindle (81) of the rotating device (80), so that the τ-shaped column (83) is pressed against the edge of the clamping surface (811) And compressing the elastic member (832), thereby being able to push open the door body; when the door body is rotated, the τ-type column (83) is disengaged from the positioning surface (811) of the mandrel (81), and against the mandrel (81) The circumference of the shaft will cause the mandrel (8)). The wrap-type column (83) will be affected by the top, and the differential rotation will be reversed, and the positioning surface (811) of the mandrel (81) will be rotated to the receiving hole (824). ), will make the T-pillar (83) elastic The member (832) supports the top surface and abuts against the positioning surface (81) of the spindle (81), thereby automatically resetting the spindle (81) and forming a positioning state. It is not difficult to find out the shortcomings of the above-mentioned conventional structure. The main reasons are as follows. (1) The conventional hinge structure, when the rotation angle of the mandrel (81) is at right angles to the τ-type column (), the T-shape will be made. The column (83) directly abuts against the tangent position of the circumference of the shaft of the mandrel (81), so that the mandrel (81) cannot reliably reverse rotation and automatically resets, which is inconvenient to use. (2) The conventional hinge structure, in which the canopy (8〇 is rotated, the end of the contact surface (811) is pressed against the butt-shaped column (83)', and then the τ-shaped column (83) is separated from the positioning surface (811) ), and supported on the shaft of the mandrel (81), and the elastic process causes the τ-type main (83) to collide with the mandrel (81) to generate a buzzer', thereby forming a problem of use, and further, The mandrel (3)) will constantly rub against the Τ-shaped column (83) during the rotation, and it is easy to generate 201245553 wear, and thus increase the volume of the rotation of the mandrel (81). In view of this, the inventor Bento Experience in manufacturing development and design of related products, detailed design and careful evaluation for the above objectives After the evaluation, it is finally the case that the invention is practical. SUMMARY OF THE INVENTION Technical problems to be solved: (1) A conventional hinge structure, when the rotation angle of the mandrel is at a right angle to the T-shaped column, the Τ-shaped column is directly erected against the tangent position of the periphery of the mandrel shaft. Therefore, the tangential component is not used, so that the mandrel cannot be surely reversely rotated and automatically reset, resulting in inconvenience in use. (2) The hinge structure of the conventional structure, when the mandrel is rotated, it first moves to the aging age with the end edge of the positioning surface, which in turn makes the heterozygous surface, and the shaft of the mandrel, and the elastic process will make It is difficult to collide with the mandrel to generate noise, and then form a trouble with the use of 'the more' of the mandrel in the process of rotation, the crane and the τ-type column rub each other's green and raw silk, to improve the heart, turn volume. Technical Solution for Solving the Problem: The present invention provides a pivoting device structure for a door hinge, comprising: a rotating shaft, the cross-sectional shape of the rotating shaft is slightly heart-shaped, and an inner curved surface is formed at the periphery.
