4. The method of making a strap of claim 3, including, after said step of providing a mold having a face provided with projections and before said step of providing a first stock material and forming a first strap blank using said mold, the steps of:
providing a tape head and a clamp, wherein the tape head comprises an insert and a plug which are connected with each other; and fixing the plug to the clamp, wherein the insert is positioned between the middle plate and the lower die, and a gap is formed between the insert and the lower die.
5. The method of making a strap of claim 4 wherein an included angle exists between said insert and said plug.
6. The method for manufacturing a binding band according to claim 4, wherein a working surface of the lower die at an end close to the plug is an arc-shaped working curved surface which is gradually inclined and concave inwards in a direction close to the plug, and the plug is parallel to a tangent line of an end portion of the arc-shaped working curved surface close to the plug.
7. The method of making a strap of claim 4, wherein said step of providing a first stock and forming with said mold to provide a first blank includes hot press forming or injection molding the first stock between said middle plate and said lower mold to provide the first blank, and wherein at least a portion of said insert is wrapped by said first blank.
8. The method of manufacturing a strap according to claim 7, including a step after the step of providing a first raw material and molding the first raw material with the mold to obtain a first tape blank, the step of forming a groove in the first tape blank at a position corresponding to the protrusion and before the step of fixing the electronic component to the groove, the method including:
and removing the clamp, opening the mold and removing the middle plate.
9. The method of manufacturing a strap according to claim 7, wherein the step of placing the first tape blank with the electronic component in the mold includes placing the first tape blank with the electronic component in the lower mold, wherein a side of the first tape blank facing away from the groove is fitted to the lower mold, and closing the upper mold and the lower mold, wherein a gap exists between the first tape blank and the upper mold, and a gap exists between the insert and the upper mold.
10. The method of manufacturing a strap according to claim 9, wherein the first material and the second material are made of the same material; the insert is provided with a through hole, and the through hole is filled with the first raw material or the second raw material.
11. The method for manufacturing a binding band according to any one of claims 1 to 10, wherein the electronic component includes a chip, and the chip is adhesively fixed to the groove.
12. A wearable device, comprising an electronic device body and the strap manufactured by the method for manufacturing a strap according to any one of claims 1 to 11, wherein the electronic device body is provided with a mounting groove, and the strap can be mounted in the mounting groove.
