Detailed implementation mode

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0027] However, in actual use, since the connection between the watch and the dial is tight, after fixing it with a clamping device and then prying open the back cover with a crowbar, scratches are likely to appear at the position where the side of the crowbar contacts the watch body during disassembly.

[0028] In view of this, the present invention provides a watch repair auxiliary device, which solves the problem that in actual use, since the connection between the watch and the dial is tight, after fixing it with a clamping device and then prying open the back cover with a crowbar, scratches are likely to appear at the position where the side of the crowbar contacts the watch body during disassembly.

[0029] Those skilled in the art connect the components in this case in sequence. For the specific connection and operation sequence, reference should be made to the following working principle. The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process.

[0030] Embodiment 1: Consisting of Figures 1-8It can be seen that a watch repair auxiliary device includes a base 1. On one side of the top of the base 1, a first support frame 11 is fixedly connected. On the other side of the top of the base 1, a second support frame 12 is fixedly connected. Below the first support frame 11, there is an opening and closing device 2. The bottom of the opening and closing device 2 is attached to a fixing strip 13. The bottom of the fixing strip 13 is fixedly connected to the top of the base 1. Below the second support frame 12, there is a pressing structure 3. The pressing structure 3 includes: a limiting block 31, connected to the top of the base 1; wherein the limiting block 31 and the base 1 are rotatably connected, a fixing cylinder 32, arranged above the limiting block 31 and fixedly connected to the inner wall of the second support frame 11; a handle 33, arranged above the fixing cylinder 32; a fixing rod 34, fixedly connected to the bottom of the handle 33, threadedly connected to the inner wall of the fixing cylinder 32 and passing through the fixing cylinder 32; a fixing block 35, fixedly connected to the bottom of the fixing rod 34; wherein, the fixing cylinder 32 fixes the fixing rod 34, and the fixing block 35 is used to install a pry bar. Through the cooperation of the limiting block 31 and the fixing block 35, by driving the fixing rod 34 to rotate with the handle 33, the fixing rod 34 drives the fixing block 35 to lift and lower;

[0031] In the specific implementation process, it is particularly worth noting that with the cooperation of the limiting block 31, the fixing cylinder 32 and the handle 33, place the watch in the slot on the top of the limiting block 31 and rotate the handle 33 to make the fixing rod 34 rotate inside the fixing cylinder 32. Since the inner wall of the fixing cylinder 32 is threadedly connected to the outer wall of the fixing rod 34, when the fixing rod 34 rotates, it will lift and lower inside the fixing cylinder 32 and drive the pry bar at the bottom of the fixing block 35 to lift the watch cover, which can avoid leaving scratches on the surface;

[0032] Furthermore, the opening and closing device 2 includes: a clamping plate 21a, arranged below the first support frame 11; a threaded rod 22a, arranged below the clamping plate 21a; a moving strip 23a, slidably clamped on the top of the fixing strip 13, and the inner wall is threadedly connected to the outer wall of the threaded rod 22a and fixedly connected to the bottom of the clamping plate 21a; a limiting post 24a, slidably clamped inside the moving strip 23a; an opening structure 25a, arranged above the clamping plate 21a; wherein, the moving strip 23a drives the clamping plate 21a to move. Through the cooperation of the threaded rod 22a and the moving strip 23a, the moving strip 23a moves on the outer wall of the limiting post 24a to fix the watch with the clamping plate 21a and use the opening structure 25a to open it;

After aligning them, the pressing plate 21b is pressed downwards. The pressing plate 21b is used to close the back cover of the watch. Moreover, cushion plates are installed on both the placing plate 22b and the pressing plate 21b to prevent the watch from being damaged during the pressing process;

[0036] Specifically, when using this watch repair auxiliary device, the watch is placed in the slot on the top of the limit block 31, and the handle 33 is rotated to make the fixing rod 34 rotate inside the fixing cylinder 32. Since the inner wall of the fixing cylinder 32 is threadedly connected to the outer wall of the fixing rod 34, when the fixing rod 34 rotates, it will lift and lower inside the fixing cylinder 32, and drive the pry bar at the bottom of the fixing block 35 to open the watch cover, which can avoid leaving scratches on the surface. Before opening, the watch dial is placed between the clamping plates 21a, the threaded rod 22a is rotated to make the moving strip 23a move towards the middle, so that the clamping plates 21a fix the watch, and the back cover is separated by the opening structure 25. When installing the back cover, the repaired watch dial is placed on the placing plate 22b, and the back cover is placed on the watch. After aligning them, the pressing plate 21b is pressed downwards. The pressing plate 21b is used to close the back cover of the watch. Moreover, cushion plates are installed on both the placing plate 22b and the pressing plate 21b to prevent the watch from being damaged during the pressing process.
