In this embodiment, the projection 113 is a cylindrical projection 113, and the cylindrical projection is fixed in the width direction of the wing plate 11 along the axial direction 113. More than one pull tab 20 is adopted, and the connecting parts 21 of the pull tabs 20 are respectively and rotatably connected to the corresponding convex blocks 113, that is, at least one pull tab 20 is respectively and rotatably connected to each convex block 113, so that the combination of the pull tabs 20 and the wing plates 11 can achieve the effects of stability and balance, and when the slider 100 is used, the pull tabs 20 connected to the convex blocks drag the main body 10 to move more stably. Preferably, the number of the pull tabs 20 is two, and the connecting portions 21 of the two pull tabs 20 are respectively and correspondingly rotatably connected to the protrusions 113 of the two wing plates 11, so that when the slider 100 is used, the pull tab 20 on one side is directly pulled, the pull tab 20 on the other side can be simultaneously driven, and the whole slider 100 can be moved.

Referring to fig. 3 to 5, in an embodiment, the bump 113 is provided with a connecting channel 114, the rotating shaft 40 is disposed in the connecting channel 114, and two ends of the rotating shaft 40 respectively extend out of the connecting channel 114 and are inserted into the connecting portion 21. When mounting, the rotating shaft 40 is first inserted into the connecting channel 114, and the rotating shaft 40 can freely rotate in the connecting channel 114. The connection part 21 of the pull tab 20 is inserted into the protrusion 113 through the connection groove 211, and then both ends of the rotation shaft 40 are respectively inserted into the connection parts 21. The connecting portion 21 has a connecting hole 212, the rotating shaft 40 is clamped in the connecting hole 212, or the rotating shaft 40 is tightly matched with the connecting hole 212, or the connecting hole 212 is rotatably connected to the rotating shaft 40, only the connecting portion 21 can rotate relative to the protruding block 113, and the specific connecting mode of the connecting portion 21 and the rotating shaft 40 can be determined by the actual situation.

In one embodiment, the protrusion 113 has a column, and the connecting portion 21 has a mounting hole corresponding to the column, and the column is disposed through the corresponding mounting hole. The columns are arranged at the two ends of the protruding block 133, the columns are arranged on the mounting holes in a penetrating mode, the connecting structures are arranged on the mounting holes in a penetrating mode through the columns, and the structure is simple and convenient to assemble. The main body is provided at both ends of the projection 133 in the direction perpendicular to the moving direction of the element row in this embodiment.

Referring to fig. 2 to 5, in one embodiment, the protrusion 113 is disposed on the tail 112 of the wing plate 11. The lug 113 is arranged at the tail part 112 of the wing plate 11, and the connecting part 21 which is rotatably connected with the lug 113 is also arranged at the tail part 112 of the wing plate 11, so that the pulling force acting on the pull tab 20 when the pull tab 20 is dragged is on the same straight line with the moving direction, and the effect of saving labor is achieved.

Specifically, the pull tab 20 further includes a handheld portion 22 connected to the connecting portion 21, the wing plates 11 are provided with limiting portions 115, and the limiting portions 115 are located at two end sides of the protruding block 113 and are used for limiting a rotation angle of the handheld portion 22 towards a position between the two wing plates 11. Specifically, the limiting portion 115 is a block structure, and the limiting portion 115 is connected to the inner side surface of the wing plate 11, that is, when the handheld portion 22 rotates along with the connecting portion 21, the handheld portion 22 can rotate towards the outer side surface of the wing plate 11, and when the handheld portion 22 rotates towards the inner side surface of the wing plate 11, the limiting portion 115 can limit the rotation of the handheld portion 22 and the connecting portion 21. By providing the stopper portions 115 on both end sides of the projection 113, when the connecting portion 21 is rotated on the projection 113 of the wing plate 11, the stopper portions 115 can restrict the hand-held portion 22 from rotating toward between the two wing plates 11, avoiding interference of the hand-held portion 22 with the element rows and the tape when the slider 100 slides on the element rows. The handle 22 may be a sheet structure, and a through hole 221 is formed on the sheet structure to facilitate the user to hold the handle. The connecting portion 21 may be two symmetrical hollow cylinders disposed at one end of the handle portion 22, and the two hollow cylinders of the connecting portion 21 are rotatably connected to two ends of the protrusion 113 to achieve the effect of the pull tab 20.

Referring to fig. 4 or 5, in an embodiment, the inner side surface of the wing plate 11 is provided with a guide groove 116. With the guide groove 116 formed in the wing plates 11, when the element row passes between the two wing plates 11, the element row is guided by the guide groove 116, so that the sliding effect of the slider 100 on the element row is ensured.

Referring to fig. 4 or fig. 5, in one embodiment, the bottom of the guiding groove 116 is formed with a groove 117, and the groove 117 is disposed at one side of the guiding pillar 12. When the slider 100 is attached with the fastener element row, the fastener element row enters between the two wing plates 11 from the head portions of the wing plates 11 through the groove 117 formed in the bottom of the guide groove 116, and the groove 117 can facilitate the attachment of the fastener element row.

Referring to fig. 2, in one embodiment, the outer side of the wing plate 11 is provided with a convex structure 118. The outer side surfaces of the two wing plates 11 are respectively provided with the convex structures 118, when the slider 100 slides on the fastener element rows, the convex structures 118 of the wing plates 11 effectively reduce the contact area of the wing plates 11 and clothes, namely, the friction force received by the wing plates 11 is reduced, so that the slider 100 can move more conveniently.

The utility model provides a pull head 100 is when using for wear to establish on the chain tooth row, in order to supply to pull open the chain tooth row or pull close the chain tooth row. The pull tab 20 is rotatably connected to the protrusion 113 of the wing plate 11 through the connecting portion 21, and the two wing plates 11 are rotatably connected to the corresponding connecting portion 21 through the protrusion 113, so that the pull tab 20 and the wing plates 11 are combined to achieve the effects of stability and balance, and when the slider 100 is used, the body 10 is dragged to move more stably through the two pull tabs 20. Meanwhile, the bump 113 is arranged at the tail part 112 of the wing plate 11, and the connecting part 21 is also arranged at the tail part 112 of the wing plate 11, so that the pulling force acting on the pull tab 20 when the pull tab 20 is dragged is on the same straight line with the moving direction, and the effect of saving labor is achieved.

The head 111 of the wing plate 11 is an end of the slider 100 in a direction in which the element row can be pulled open while moving on the element row, and correspondingly, the tail 112 of the wing plate 11 is an end of the slider 100 in a direction in which the element row can be pulled close while moving on the element row. Therefore, when the fastener element row needs to be pulled open, the connecting part 21 can be rotated around the lug 113 to the side facing the head part 111 of the wing plate 11, and the fastener element row can be pulled open by pulling the hand-holding part 22 to the direction facing the head part 111 of the wing plate 11; when the zipper needs to be closed, the connecting part 21 can be rotated to the side far away from the head part 111 of the wing plate 11 around the convex block 113, and then the zipper tooth row can be closed by pulling the hand-held part 22 towards the direction far away from the side of the head part 111 of the wing plate 11. When the pull tab 20 is pulled to move the whole slider 100, the connecting portion 21 does not interfere with the cloth beside the element row because the width of the connecting portion 21 is smaller than or equal to the width of the wing plate 11, that is, the connecting portion 21 is within the width range of the wing plate 11.
