[0030] In one embodiment, the track 13 may be a slide groove or a track 13 .

[0031] In one embodiment, the fixing mechanism 12 includes: a pin body for being inserted into the vehicle body and a clamp (or a clamping cylinder) fixed on the vehicle body.

[0032] In one embodiment, the position to be rolled extends in a direction parallel to the track 13 , so that when the sliding platform 21 slides along the track 13 , the roller head 22 can move along the position to be rolled.

[0033] In one embodiment, the track 13 extends along a circular arc trajectory.

[0034] For further information, see Figures 1 to 4 As a specific embodiment of the manual hemming mechanism provided by the present invention, it also includes: a telescopic device 23 having a telescopic portion and arranged on a sliding table 21, a rotating shaft 24 arranged on the telescopic portion, a rotating table 25 arranged at one end of the rotating shaft 24, a positioning hole 251 opened on the rotating table 25, and a positioning pin 26 arranged on the sliding table 21 and used to be inserted into the positioning hole 251; the roller head 22 is rotatably arranged on the rotating table 25; when the rotating table 25 is extended with the rotating shaft 24, the positioning pin 26 is pulled out of the positioning hole 251; when the rotating table 25 is retracted with the rotating shaft 24, the positioning pin 26 can be inserted into the positioning hole 251. In this way, a telescope 23 is provided on the sliding table 21, and the telescope 23 has a telescopic part, on which a rotating shaft 24 is rotatably provided, on which a rotating table 25 is provided, and on which a roller head 22 is provided; when the telescopic part is extended, the positioning pin 26 is pulled out of the positioning hole 251 on the rotating table 25, and when the rotating shaft 24 is rotated, the position of the roller head 22 can be adjusted by the rotating table 25; after the above-mentioned rotating table 25 is rotated to align the positioning hole 251 with the positioning pin 26, when the telescopic part is retracted, the positioning pin 26 is inserted into the positioning hole 251 on the rotating table 25 to prevent the rotating table 25 from rotating around the rotating shaft 24.

[0035] In one embodiment, the retractor 23 is controlled by four control buttons 31. In one embodiment, the control buttons 31 are gas-operated buttons.

[0036] In one embodiment, the roller heads 22 are respectively rotatably arranged on the rotating platform 25 by means of shaft bodies. In one embodiment, the shaft bodies of the roller heads 22 have the same angle relative to the rotating shaft 24. Thus, when the rotating shaft 24 is rotated to rotate the rotating platform 25 to switch different roller heads 22, the inclination states of the shaft bodies of different roller heads 22 can be kept consistent.

[0037] In one embodiment, the axial cross-section of each roller head 22 is an isosceles trapezoid.

[0038] In one embodiment, the retractor 23 is a cylinder. In one embodiment, the air circuit control principle of the retractor 23 can refer to Figure 5 In one embodiment, the control button 31 cooperates with the dual air-controlled two-position five-way valve 33 to control the telescopic device 23. In one embodiment, the control process is as follows: S1: the manual hemming mechanism is placed on the fetal membrane to match the fetal membrane; S2: the cylinder is clamped by pressing the button; S3: the hemming tool is manually used for hemming; S4: the cylinder is opened by pressing the button; S5: the hemming tool is manually moved to the starting position of the hemming; S6: the hemming is repeated three times.

[0039] In one embodiment, the rotating platform 25 can be connected to the sliding platform 21 via a quick release mechanism 32 .

[0040] In one embodiment, the cross section of the track 13 is U-shaped. In one embodiment, a first roller and a second roller are provided on the sliding table 21, and the track 13 is clamped between the first roller and the second roller. In one embodiment, the first roller abuts against the inner wall of the U-shaped track 13. In one embodiment, the number of the first rollers is multiple, and the multiple first rollers are arranged in two rows, wherein one row of the first rollers abuts against one side wall of the inner wall of the U-shaped track 13, and the other row of the first rollers abuts against the other side wall of the inner wall of the U-shaped track 13. In this way, the multiple first rollers move more smoothly along the inner wall of the U-shaped track 13, and it is also convenient to distribute the stress to different first rollers, and the two side walls of the U-shaped track 13 are more evenly stressed. In one embodiment, the second roller is coaxially arranged with the sprocket 282, so that the second roller and the sprocket 282 can move synchronously to avoid collision between the two. In one embodiment, the chain 283 is laid on the surface of the track 13.

[0041] In one embodiment, the track 13 is in the shape of a long strip plate, one outer wall of the track 13 contacts the first roller, the other outer wall of the track 13 contacts the second roller, and the track 13 is clamped between the first roller and the second roller.

[0042] For further information, see Figures 1 to 4 As a specific embodiment of the manual hemming mechanism provided by the present invention, the extending direction of the positioning pin 26 is parallel to the extending direction of the positioning hole 251. In this way, the positioning pin 26 is conveniently inserted into the positioning hole 251.

[0048] For further information, see Figures 1 to 4 As a specific embodiment of the manual hemming mechanism provided by the present invention, there are three roller heads 22. In this way, hemming can be performed by different roller heads 22.

[0049] For further information, see Figures 1 to 4 As a specific embodiment of the manual hemming mechanism provided by the present invention, each roller head 22 has a conical surface for flanging. In this way, when the conical surface on the roller head 22 contacts the position where the hemming is required, the hemming can be extruded and rolled.

[0050] For further information, see Figures 1 to 4 As a specific embodiment of the manual hemming mechanism provided by the present invention, the cone angle of the cone surface on one of the roller heads 22 is: 105°~60°; the cone angle of the cone surface on one of the roller heads 22 is: 60°~30°; the cone angle of the cone surface on one of the roller heads 22 is: 30°~0°. In this way, by switching roller heads 22 with different cone angles, edges with different folding degrees can be hemmed.

[0051] For further information, see Figures 1 to 4 As a specific embodiment of the manual hemming mechanism provided by the present invention, the retractor 23 is a cylinder. Thus, it is relatively simple to use the cylinder.

[0052] For further information, see Figures 1 to 4 As a specific embodiment of the manual hemming mechanism provided by the present invention, it also includes: a knob 27 disposed on the rotating shaft 24 and used for the user to drive the rotating shaft 24 to rotate. In this way, the user can conveniently rotate the rotating shaft 24 through the knob 27.

[0053] For further information, see Figures 1 to 4 As a specific embodiment of the manual hemming mechanism provided by the present invention, it also includes: a rocker 281 arranged on the sliding table 21, a sprocket 282 connected to the rocker 281, and a chain 283 parallel to the track 13; the sprocket 282 is meshed with the chain 283. In this way, when the rocker 281 rotates, the sprocket 282 can be driven to rotate, and the sprocket 282 cooperates with the chain 283 to pull the sliding table 21 to slide.

[0054] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention.
