[0027] Through the downward movement of the first turning leather column 5, the second turning leather column 8 is moved downward, so as to drive the mounting plate 15 to move downward, because the spring 14 has a certain length, and when the second turning leather column 8 is completely located below the first pressing ring 18, the spring 14 can still be normally used, so as to provide reasonable extrusion turning for the leather, so that the turning effect is good.
[0028] The pressing structure comprises a fixed plate 17 fixedly connected to the inner side of the support 2, a first pressing ring 18 fixedly connected to the upper surface of the fixed plate 17, a fixed block 19 fixedly connected to the rear surface of the fixed plate 17, a second air cylinder 20 mounted on the lower surface of the fixed block 19, a driving C-shaped plate 21 fixedly connected to the output shaft of the second air cylinder 20, and a second pressing ring 22 fixedly connected to the lower surface of the driving C-shaped plate 21.

[0036] The working principle and use process of the utility model are as follows:
[0037] The worker puts the leather cover into the surface of the second turning column 8, at this time, the lower part of the leather cover will slightly enter the upper surface of the first pressing ring 18 from the surface of the ring 24, because the ring 24 is fixedly connected inside the first pressing ring 18, at this time, the second cylinder 20 is started, because the output shaft of the second cylinder 20 is contracted, so as to drive the C-shaped plate 21 to descend, so as to realize the extrusion and fixation of the second pressing ring 22 to the leather cover, after the fixation is completed, the first cylinder 4 is started, because the output shaft of the first cylinder 4 is extended, so as to make the leather cover turn, finally, the leather cover is located on the surface of the first turning column 5, at this time, the second cylinder 20 is started in reverse, so as to make the leather cover located on the surface of the first turning column 5, at this time, the first cylinder 4 is started in reverse, so as to make the leather cover be completely turned successfully.
[0038] Before turning the leather cover, the rotating disc 13 is rotated, because the rotating disc 13 penetrates the right support 2 and rotates inside the left support 2, so as to drive the rotation of the bidirectional threaded rod 9, at the same time, the surface of the bidirectional threaded rod 9 is screw-connected with the sliding hinge block 10, because of the design of the spiral line direction, the sliding hinge block 10 can relatively approach and move away, the hinge rod 11 is hingedly connected in the middle of the sliding hinge block 10, and the hinge rod 11 and the fixed hinge block 12 are also hingedly connected in the middle, so as to drive the support plate 6 fixedly connected to the upper surface of the fixed hinge block 12 to realize lifting.
[0039] Through the downward movement of the first turning column 5, the second turning column 8 is moved downward, so as to drive the mounting plate 15 to move downward, because the spring 14 has a certain length, and when the second turning column 8 is completely located below the first pressing ring 18, the spring 14 can still be normally used, so as to provide reasonable extrusion turning to the leather, so as to make the turning effect good.
[0040] The fixed plate 17 provides support force to the first pressing ring 18, at the same time, the second cylinder 20 is started, because the output shaft of the second cylinder 20 is contracted, so as to make the driving C-shaped plate 21 move downward, so as to realize the extrusion and fixation of the second pressing ring 22 and the first pressing ring 18 to the opening of the leather cover.
[0041] The limiting column 23 provides stability for the upward and downward movement of the driving C-shaped plate 21, so as to improve the stability of the extrusion between the second pressing ring 22 and the first pressing ring 18.
[0042] By putting the leather cover into the surface of the second turning column 8, and extruding the leather cover downward with very small force, the lower opening of the leather cover will first contact the upper surface of the ring 24, with the increase of the force, the leather cover will turn outward and enter the upper surface of the first pressing ring 18, so as to be beneficial to the extrusion of the lower part of the leather cover, if the ring 24 does not exist, the leather cover cannot be extruded smoothly.
[0043] The support plate 6 can be smoothly moved up and down in the support 2 by the action of the chute 25, which is conducive to preventing the support plate 6 from turning, thereby causing the internal thread of the sliding hinge block 10 to slip or causing the hinge rod 11 to be damaged.
