When the pull body 1 is a pull tab body 1b directly connected to the pull head 100, the connecting portion 12 of the pull tab body 1b can be a pull cord, and the pull cord is directly connected to the pull head 100. Of course, the above is only a preferred embodiment of the connection between the connecting portion 12 and the pull head 100 of the present invention, but the present invention is not limited thereto. In specific implementation, the connecting portion 12 of other structures can also be used to connect with the pull head 100.

As the third specific embodiment of the present invention, please focus on Figures 5 to 8, the pull body 1 is a pull tab body 1b connected to the pull tab body 1a, and the pull tab body 1a is connected to the slider 100. When the pull body 1 is a pull tab body 1b connected to the pull tab body 1a, one end of the pull tab body 1a can be provided with a first mounting through hole 121 running from the top to the bottom, so as to utilize the first mounting through hole 121 to realize the assembly of the pull tab body 1a and the slider 100 together; of course, the above is only a preferred embodiment of the connection between the pull tab body 1a and the slider 100 of the present invention, but the present invention is not limited thereto, and in specific implementation, the pull tab body 1a can also adopt other structures to realize the connection with the slider 100. One end of the pull tab body 1a may be provided with a second mounting hole 122 extending from the top to the bottom, and the pull tab body 1b may be a long strip of sheet material with both ends kept open but folded in half and a ring-shaped portion in the middle, the ring-shaped portion being the connecting portion 12 of the pull tab body 1b, and the connecting portion 12 of the pull tab body 1b is assembled on the second mounting hole 122 of the pull tab body 1a; of course, the above is only a preferred embodiment of the connection between the pull tab body 1b and the pull tab body 1a of the present invention, but the present invention is not limited thereto, and in specific implementation, other structures may be used to achieve connection between the pull tab body 1b and the pull tab body 1a, and the pull tab body 1b may also adopt various existing pull tab structures, for example, the connecting portion 12 of the pull tab body 1b may adopt a drawstring, and the drawstring is connected to the pull tab body 1a.

In some embodiments of the present invention, the adhesive coating 2 is stacked and cured layer by layer by the silicone dot array 4 to the desired height, thereby obtaining each of the elastic columns 3. In the embodiment of the present invention, since the elastic columns 3 are obtained by stacking and curing the silicone dot array 4 layer by layer, the elastic columns 3 are cylindrical in structure as a whole. Of course, the above is only a preferred embodiment of the present invention, but the present invention is not limited thereto. In the specific implementation, silicone dot arrays of other shapes, such as silicone elliptical dot arrays, can also be used. In the specific implementation of the present invention, the silicone dot array 4 can be automatically stacked using an automated silicone overprinting device, which can not only achieve more accurate positioning, but also improve production efficiency and reduce costs.

Furthermore, the silicone dot array 4 includes a plurality of neatly arranged columns of liquid silicone dots 41, and the circular diameter of a single liquid silicone dot 41 is 0.3-1 mm. For example, the circular diameter of a single liquid silicone dot 41 can be set to any one of 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, and 1 mm. Of course, the above is only a preferred embodiment of the present invention, but the present invention is not limited thereto. In specific implementation, the circular diameter of a single liquid silicone dot 41 can be adjusted according to actual needs. In the silicone dot array 4 of the present invention, the specific number of columns of the liquid silicone dots 41 can be set according to the size of the coating contour area 111, and the number of the liquid silicone dots 41 in each column can also be set as needed. At the same time, when the circular diameter of a single liquid silicone dot 41 is too small, it will be difficult to accurately perform the stacking operation; and when the circular diameter of a single liquid silicone dot 41 is too large, it will be difficult to set a sufficient number of the elastic columns 3 in the coating contour area 111 of the pulling body 1, which will affect the actual use effect; the present invention designs the circular diameter of a single liquid silicone dot 41 to be 0.3-1mm, which is convenient for accurately stacking the silicone dot array 4 and ensures that a sufficient number of elastic columns 3 can be set in the limited coating contour area 111 to improve the use effect.

Furthermore, the thickness of the single-layer silicone dot array 4 is 0.15-0.3mm. For example, the thickness of the single-layer silicone dot array 4 can be set to any one of 0.15mm, 0.18mm, 0.21mm, 0.25mm, 0.28mm, and 0.3mm; the overall height of the elastic column 3 is 1-8mm. For example, the overall height of the elastic column 3 can be set to any one of 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, and 8mm; of course, the above is only a preferred embodiment of the present invention, but the present invention is not limited to this. In specific implementation, the thickness of the single-layer silicone dot array 4 and the overall height of the elastic column 3 can be adjusted according to actual needs. In the specific implementation, if the thickness of the single-layer silicone dot array 4 is too thin or too thick, the stacking of the silicone dot array 4 will be affected; at the same time, if the overall height of the elastic column 3 is too low, it will not be possible to intuitively form a brush-like structure, the sensory experience will be poor, and the tactile feel cannot be guaranteed; and if the overall height of the elastic column 3 is too high, it will be inconvenient for the user to grasp, and the tactile feel will also be poor; the present invention designs the thickness of the single-layer silicone dot array 4 to be 0.15-0.3mm, and the overall height of the elastic column 3 to be 1-8mm, which can facilitate the stacking and curing of the silicone dot array 4, and can also ensure the tactile feel and enhance the sensory experience.

In some embodiments of the present invention, the holding body 1 is a sheet-like body to facilitate the user to grasp. Of course, the above is only a preferred embodiment of the present invention, but the present invention is not limited thereto. In the specific implementation, other forms of the holding body 1 can also be used. In the specific implementation of the present invention, a coating contour area 111 can be formed on the upper surface and/or lower surface of the gripping portion 11 of the holding body 1, and an adhesive coating 2 and an elastic column 3 can be provided on the upper surface and/or lower surface of the gripping portion 11; at the same time, the coating contour area 111 can be a concave area, a convex area, or an area that is flush with the upper surface and/or lower surface of the gripping portion 11 formed on the upper surface and/or lower surface of the gripping portion 11.

The holding body 1 is made of a webbing material, a textile-like belt-shaped material, a metal material or an injection-molded material. When the present invention is implemented, the material of the holding body 1 can be set according to actual use needs. For example, when the holding body 1 is a pull-tab body 1a directly connected to the slider 100, the pull-tab body 1a can be made of a metal material (such as zinc alloy, copper, iron, etc.) or an injection-molded material; for another example, when the holding body 1 is a pull tab body 1b connected to the pull tab body 1a, the pull tab body 1a can be made of a metal material or an injection-molded material, and the pull tab body 1b can be made of a webbing material or a textile-like belt-shaped material, and so on.

In some embodiments of the present invention, the adhesive coating 2 is a resin glue adhesive coating, and the thickness of the adhesive coating 2 is 0.2-0.5 mm. For example, the thickness of the adhesive coating 2 can be set to any one of 0.2 mm, 0.3 mm, 0.4 mm, and 0.5 mm. Of course, the above is only a preferred embodiment of the present invention, but the present invention is not limited to this. In specific implementation, the type of glue used in the adhesive coating 2 and the thickness of the adhesive coating 2 can be adjusted according to actual needs. In a specific implementation, the surface adhesion of the gripping portion 11 of the holding body 1 is very poor. If the elastic column 3 is directly set on the surface of the gripping portion 11, the elastic column 3 will easily detach from the surface of the gripping portion 11. The present invention sets a coating contour area 111 on the surface of the gripping portion 11, and first sprays a certain thickness of resin glue in the coating contour area 111 to form an adhesive coating 2, and then sets the elastic column 3 on the surface of the adhesive coating 2. In this way, each elastic column 3 can be bonded to the adhesive coating 2 as a whole, and the contact area between the adhesive coating 2 and the surface of the gripping portion 11 is large. Therefore, the elastic column 3 can be reliably bonded to the gripping portion 11 of the holding body 1, thereby ensuring that the elastic column 3 will not detach during use.
