The main body 11 and the two buckles 12 define a condensing space 14 with an opening. The main body 11 can be divided into an inner arc side 111 and an outer arc side 113. The inner arc side 111 is formed with a plurality of bumps 112. The central part of the main body 11 is provided with a cutout 15 to reduce the thickness of the structure. Preferably, the cutout 15 continues to the outer arc side 113. The main body 11 is provided with a plurality of mechanical workpiece clamping positions 16. In the illustration, the clamping position 16 is a hole penetrating the structural thickness of the main body 11.

The inner surface 122 of the two buckle feet 12 is flat, but it is not limited to this, and may also be a tooth surface. The open ends 121 of the two buckle feet 12 are configured to be tapered. The outer side surfaces 123 of the two buckle feet 12 are respectively provided with a plurality of buckle teeth 13, a tooth groove 134 is formed between the two adjacent buckle teeth 13, and each buckle tooth 13 includes a helical tooth surface 131 and a flat tooth surface 132. The intersection of the two forms a rounded tooth top 133.

The surface of the second buckle 20 facing the first buckle 10 is defined as the inner side surface 21, and the surface different from the inner side surface 21 is defined as the outer side surface 22. The inner surface 21 is provided with an arc-shaped recess 211. The central part of the second buckle 20 is provided with a cutout 23 to reduce the thickness of the structure. Preferably, the cutout 23 continues to the outer surface 22.

The second buckle 20 is provided with a through opening 24 at both ends, and each through opening 24 includes a first inner side wall 241 and a second inner side wall 242, the first inner side wall 241 and the second inner side wall 242 constitutes a through opening width W1, the through opening width W1 is greater than a maximum width W2 of the buckle 12, the relative distance D1 between the two second inner side walls 242 is equal to the opposite distance D2 between the two tooth tops 133; The second inner wall 242 of the through opening 24 is provided with a limiting tooth 25. The limiting tooth 25 includes an intersecting helical tooth surface 251 and a flat tooth surface 252, and the helical tooth surface 251 faces the first buckle 10 The buckle foot 12. The second buckle 20 has a plurality of mechanical workpiece clamping positions 26. In the example, the clamping position is a hole penetrating the structural thickness of the second buckle 20.

The mechanical workpieces that move linearly toward the reset clamp the mechanical workpiece clamping positions 16, 26 of the first and second tie buckles 10 and 20, and operate the first tie buckle 10 and the second tie buckle 20 to move accordingly. As shown in Fig. 5 to Fig. 8, after the bag opening 30 of a container bag is roughly condensed, it is stuffed into the condensing space 14 of the first buckle 10, and then the two buckles of the first buckle 10 The feet 12 respectively penetrate into the two through openings 24 of the second buckle 20. Based on the width of the through opening 24 being greater than the maximum width of the buckle 12, and the open end 121 of the buckle 12 is tapered, the The buckle 12 can smoothly enter the through opening 24; further, based on the relative distance D1 formed by the second inner side wall 242 is equal to the relative distance D2 of the two tooth crests 133 opposite to each other, the two buckles 12 enter the two When passing through the opening 24, the tooth top 133 can contact or be very close to the second inner side wall 242, so the helical tooth surface 131 of the buckle tooth 13 can push against the helical tooth surface 251 of the limiting tooth 25, so that the first A tether 10 and the second tether 20 move relative to each other, and the second tether 20 reduces the constricting space 14 so that the bag opening 30 is tightly tightened. The tightened bag opening will also block the first tie buckle 10 and the second tie buckle 20 so that they cannot move relative to each other. At this point, the flat tooth surface 132 of the buckle tooth 13 and the flat tooth surface 252 of the limiting tooth 25 block each other, so that the first buckle 10 and the second buckle 20 cannot move away in the opposite direction, and tighten accordingly. The pocket opening 30 is limited between the first buckle 10 and the second buckle 20. The inner arc side 111 of the first buckle 10 and the recess 211 of the second buckle 20 make the pocket opening 30 tighter. It can tend to a cylindrical shape, and the several convex points 112 on the inner arc side 111 increase the opening of the first buckle 10 30's tightening grip.
