The drive control component includes an inner tube 11, which is inserted into the fixed block 8. The inner tube 11 is a hollow circular tube structure. Two side holes 14 are opened on both sides of the center of the inner tube 11. Two connecting rods 13 are movably arranged inside the inner tube 11. The connecting rods 13 are connected with a first clamp 1301 and a second clamp 1302. The first clamp 1301 is arranged at the open ends on both sides of the inner tube 11 and is sleeved on the connecting rod 13. One end of the connecting rod 13 close to the opening of the inner tube 11 passes through the side wall of the fixed block 8 and passes through the side wall of the strap 2 and is inserted into the connecting hole 4. This end is smaller than the diameter of the remaining part. The second clamp 1301 is connected to the inner tube 11. 1302 is fixed to the other end of the connecting rod 13, and a steel needle 1304 is inserted on the second clamp 1302, and both ends of the steel needle 1304 extend out from the side hole 14, and a spring 1303 is arranged between the first clamp 1301 and the second clamp 1302, and the spring 1303 applies a pulling force to the second clamp 1302; a square groove is arranged on the fixing block 8, and the middle part of the inner tube 11 is located in the square groove, and a button 9 is movably inserted in the square groove, and openings are arranged on the left and right side walls of the button 9, and the inner tube 11 is located in the opening, and side openings 12 are opened on the front and rear side walls of the button 9, and the steel needle 1304 is located in the side opening 12.

[0029] A 45° guide surface 1201 is provided at both ends of the side opening 12, and a hook portion 1202 is provided below the guide surface 1201. A steel needle 1304 is against the inner wall of the side opening 12, and a spring 1303 pulls the second clamping head 1302 to both sides so that the steel needle 1304 is located in the hook portion 1202. When the button 9 is subjected to pressure reduction, the steel needle 1304 is subjected to pressure and moves along the guide surface 1201, so that the connecting rod 13 can move toward the middle part of the inner tube 11, thereby causing the end of the connecting rod 13 to move out of the connecting hole 4.

[0030] The strap 2 is provided with a mounting groove 7, and the surface of the mounting groove 7 is provided with a coating 5, which is a relatively soft material and is used to cover the mounting groove 7 for better appearance. The mounting groove 7 is communicated with the inner cavity 6, and a movable part 15 is provided in the mounting groove 7. The movable part 15 is used to limit and hide the button 9. A card slot 901 is provided on the side wall of the button 9, and the movable part 15 includes a covering portion 16 and an embedded portion 17. The embedded portion 17 is movably arranged in the mounting groove 7, and a card plate 18 is provided at the connection between the embedded portion 17 and the bottom surface of the covering portion 16, and the card plate 18 corresponds to the card slot 901. When the card plate 18 is inserted into the card slot 901, the button 9 is fixed and cannot move. A telescopic elastic member 20 is provided in the mounting groove 7, and the telescopic elastic member 20 abuts against the end of the embedded portion 17. The telescopic elastic member 20 applies a thrust to the embedded portion 17, thereby ensuring that the card plate 18 can be inserted into the card slot 901 when worn.

[0031] The end of the cover portion 16 is an arc-shaped structure, which is used to fit the bottom of the watch case. A square embedding groove is provided on the bottom surface of the cover portion 16. The square embedding groove is adapted to the shape of the button 9. When the cover portion 16 covers the button 9, the button 9 can be covered to prevent the bulge from affecting the wearing. Limiting bosses 19 are provided on both sides of the embedded portion 17, and a limiting slide groove 701 is provided on the inner side wall of the installation groove 7. The limiting boss 19 is slidably embedded in the limiting slide groove 701, so that the embedded portion 17 can be stably installed in the installation groove 7.

[0032] When assembling the watch strap 2, the fixing block 8 is bonded to the inside of the inner cavity 6 by hot pressing, the inner tube 11 is inserted from the side hole of the watch strap 2, the inner tube 11 is rotated so that the side hole 14 faces upward and the mounting hole on the second clamp 1302 faces upward, and then the two steel needles 1304 are inserted into the second clamp 1302, and then the inner tube 11 is rotated so that the steel needles 1304 become horizontal, and then the exposed parts of the connecting rods 13 at both ends are pressed to make the steel needles 1304 approach each other. When the distance between the two steel needles 1304 is smaller than the notch at the bottom of the side opening 12, the button 9 is inserted into the square groove, and the connecting rods 13 at both ends are loosened. At this time, under the influence of the pulling force of the spring 1303, the connecting rods 13 at both ends move to both sides so that the steel needles 1304 move away from each other and then get stuck in the hook part 1202, and the assembly is completed.

[0033] When connecting the watch case 1 and the watch strap 2, it is only necessary to press the button 9 downward, and the guide surface 1201 will apply pressure to the steel needle 1304, so that the steel needle 1304 can drive the connecting rod 13 to move. When the end of the connecting rod 13 is received in the watch strap 2, the end of the watch strap 2 is placed in the connecting ear 3, and then the spring 1303 rebounds to pull the connecting rod 13 back, so that the end of the connecting rod 13 can be inserted into the connecting hole 4 to complete the connection. When an accessory fails and needs to be disassembled and repaired, it is only necessary to press the button 9 during disassembly. The operation is more convenient and can be applied to different watch straps 2. Pliers or tools are used to press in the end 13 of the connecting rod. At this time, the steel needle 1304 is close to the middle and can be detached from the side opening 12, thereby removing the button 9. Compared with other structures on the market, disassembly and maintenance do not require screws to be removed, which is faster and more efficient.

[0034] In order to prevent the button 9 from being accidentally touched during use and to prevent the strap 2 from accidentally falling off, a movable part 15 is provided, and the telescopic elastic part 20 pushes the movable part 15 forward so that the card plate 18 is inserted into the card slot 901, and the button 9 does not drop. Therefore, the connecting rod 13 can be stably inserted into the connecting hole 4, and the covering part 16 covers the button 9 to prevent the protrusion of the button 9 from affecting the discomfort of wearing.
