Therefore, when the clamping piece 63 is used for a long time and is worn, it is only necessary to replace the elastic rubber layer 64 clamped with the clamping piece 63. On the other hand, due to the action of the spring 62, the contact between the clamping piece 63 and the watchband is closer when clamping the watchband, thereby avoiding the watchband from falling off due to the wear of the clamp 2, thereby improving the efficiency of polishing the watchband.

[0028] As a possible implementation manner of the present scheme, preferably, the clamping member 63 includes a guide block 631 fixedly connected to the end of the spring 62, a guide plate 632 fixedly connected to the guide block 631, and a splint 633 fixedly connected to the guide plate 632; the elastic rubber layer 64 is clamped on one side of the splint 633; ​​through the cooperation of the guide block 631, the guide plate 632 and the splint 633, the device can be made more stable during operation.

[0030] As a possible implementation of the present scheme, preferably, the elastic block 641 includes a connecting column 642 fixed to the elastic rubber layer 64 and an elastic hemispherical block 643 fixed to the end of the connecting column 642, and the radius of the elastic hemispherical block 643 is greater than the radius of the connecting column 642; through the cooperation between the connecting column 642 and the elastic hemispherical block 643, on the one hand, the connecting column 642 can provide supporting force for the elastic block 641 to prevent the elastic block 641 from being too soft and easily detached from the splint 633; ​​on the other hand, the setting of the elastic hemispherical block 643 can make the connection between the elastic block 641 and the slot 634 more firmly.

[0032] As a possible implementation mode of the present scheme, preferably, the polishing assembly 3 includes a mounting frame 31 slidably connected to the top of the workbench 1, rotating rollers 32 symmetrically arranged at both ends of the mounting frame 31, a polishing wheel 33 fixedly connected to the rotating rollers 32, and a transmission belt 34 installed inside the mounting frame 31; the two ends of the transmission belt 34 are respectively fixedly connected to the two rotating rollers 32; the rotating rollers 32 are driven to rotate by the transmission belt 34 to achieve grinding and polishing of both sides of the watch strap, thereby improving the polishing efficiency of the device.

[0033] The working principle of this device is:

[0034] When the watch strap needs to be clamped and polished, the two ends of the watch strap are respectively placed on the top of the clamping plates 633 located at the bottom of the two sets of clamps 2 and passed between the two polishing wheels 33 in the mounting frame 31, and then the driving motors 51 on both sides are driven respectively to make the lower clamping plate 633 and the upper clamping plate 633 approach each other, so as to clamp the end of the watch strap, and by driving the mounting frame 31, the polishing assembly 3 is moved along the watch strap, so as to achieve all-round polishing and grinding of the watch strap, and while the mounting frame 31 drives the polishing assembly 3 to move, the rotating motor fixed on the mounting frame 31 is started, so that the transmission belt 34 drives the two sets of rotating rollers 32 to rotate, so as to achieve polishing and grinding of both sides of the watch strap; when the use time is long, the polishing assembly 3 is driven to move, and the rotating motor fixed on the mounting frame 31 is started, so that the transmission belt 34 drives the two sets of rotating rollers 32 to rotate, so as to achieve polishing and grinding of both sides of the watch strap; when the watch strap is used for a long time, the polishing assembly 3 is driven to move, and the rotating motor fixed on the mounting frame 31 is started, so that the transmission belt 34 drives the two sets of rotating rollers 32 to rotate, so as to achieve polishing and grinding of both sides of the watch strap. When the elastic rubber layer 64 engaged with the splint 633 is worn, the elastic rubber layer 64 is stretched to both sides so that the two groups of elastic blocks 641 are respectively disengaged from the two slots 634, and then the new elastic rubber layer 64 is stretched to both sides so that the two groups of elastic blocks 641 are respectively aligned with the two slots 634, and then the hand is released so that the connecting column 642 drives the elastic hemispherical block 643 to engage with the slot 634, and the replacement is completed at this time; in the present device, a rotating motor is fixed to the side of the mounting frame 31 away from the rotating roller 32, and the rotating motor is fixedly connected to one group of gears of the transmission belt 34; in the present device, the mounting frame 31 can be driven to move by a linear drive, a screw assembly, a conveyor belt, etc.
