[0023] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Specific examples are given below.

[0025] See also Figure 1 - Figure 5 The utility model provides a processing fixture for watch production, including two connecting rod bases 1, which are hinged at the center of the contact surface of the two connecting rod bases 1. A plurality of through holes 11 are opened at both ends of the connecting rod base 1. The plurality of through holes 11 are opened equidistantly along the side wall direction of the connecting rod base 1. Notches 12 are symmetrically opened inside the through holes 11. An annular groove 13 is opened at one end of the inner wall of the through hole 11. The annular groove 13 and the notch 12 are interconnected. Clamping rods 2 are symmetrically arranged on the upper sides of the two connecting rod bases 1. The outer wall of one end of the clamping rod 2 is symmetrically fixed with a limiting protrusion 21. The limiting protrusion 21 fits with the inner wall of the annular groove 13. One end of the two connecting rod bases 1 is fixed with a linkage bracket. 14. A linkage assembly 3 is provided between the two linkage brackets 14. When the connecting rod base 1 needs to install the clamping rod 2, the limiting protrusion 21 is controlled to move downward along the notch 12, and after the limiting protrusion 21 moves to the inside of the annular groove 13, the clamping rod 2 is controlled to rotate as a whole, so that the connecting rod base 1 fixes the clamping rod 2, and by controlling the relative rotation of the two connecting rod bases 1, the dial is fixed between the outer walls of the clamping rod 2, and the device clamps and fixes the dial. The two connecting rod bases 1 are linked in cooperation with the linkage bracket 14 and the linkage assembly 3, and when the diameter of the dial changes, the relative position of the clamping rod 2 can be changed to adapt to the change, thereby ensuring that the clamping rod 2 clamps and fixes the dial.

[0026] like Figure 1 and Figure 4As shown, the linkage assembly 3 includes a bidirectional screw rod 31, and a threaded sleeve 32 is symmetrically installed on the outer wall of the bidirectional screw rod 31. The two threaded sleeves 32 are respectively screwed to the two sections of the external thread of the bidirectional screw rod 31. The two threaded sleeves 32 are respectively hinged to the inside of the two linkage brackets 14. During the rotation of the bidirectional screw rod 31, the threaded sleeve 32 can be displaced in the synchronous direction to realize the control of the relative rotation between the connecting rod base 1;

[0027] like Figure 1 and Figure 4 As shown, an annular groove 321 is formed near the outer wall of both ends of the bidirectional screw rod 31. A limit bracket 33 is clamped between the inner walls of the two annular grooves 321. A linkage base 34 is installed between one end of the two limit brackets 33. The bidirectional screw rod 31 is fixed by the linkage base 34 under the cooperation of the annular groove 321 and the limit bracket 33.

[0028] like Figure 1 、 Figure 4 and Figure 5 As shown, a rotating assembly 4 is installed at one end of the bidirectional screw rod 31, and the rotating assembly 4 includes a rotating rod 41, one end of the rotating rod 41 is fixedly connected to one end of the bidirectional screw rod 31, and one end of the rotating rod 41 is fixedly connected to a limiting circular plate 42. The outer wall of the rotating rod 41 is sleeved with a rotating handle 43, and the inner wall of the sleeve of the rotating handle 43 is fixedly connected to a handle protrusion 44. The inner wall of the handle protrusion 44 is engaged with the groove on the outer wall of the rotating rod 41. The outer wall of the rotating rod 41 is sleeved with a spring 45, and the spring 45 is located between the rotating handle 43 and the limiting circular plate 42. The sleeve of the rotating handle 43 is fixedly connected to an annular limiting strip 46 near the side wall where the limiting bracket 33 is located. The annular limit strip 46 and the convex strips on the side wall of the limit bracket 33 are engaged with each other, and the rotating component 4 controls the rotation of the bidirectional screw rod 31. The rotating rod 41 is installed at one end of the bidirectional screw rod 31. Since it is linked with the rotating rod 41 through the handle protrusion 44, the bidirectional screw rod 31 rotates synchronously when the rotating handle 43 is rotated, and when the annular limit strip 46 is engaged with the convex strips on the limit bracket 33, the bidirectional screw rod 31 is rotationally limited. When it is necessary to control the relative rotation of the connecting rod base 1, it is necessary to pull the rotating handle 43 outward to overcome the elastic force of the spring 45 between the limiting circular plate 42 and the rotating handle 43, so that the annular limit strip 46 is disengaged from the protrusion;

[0029] Working principle: When the connecting rod base 1 needs to install the clamping rod 2, the control limit protrusion 21 is moved down along the notch 12, and after the limit protrusion 21 moves to the inside of the annular groove 13, the control clamping rod 2 is rotated as a whole, so that the connecting rod base 1 fixes the clamping rod 2, and the dial is fixed between the outer walls of the clamping rod 2 by controlling the relative rotation of the two connecting rod bases 1, so that the device can clamp and fix the dial. The two connecting rod bases 1 are linked with the cooperation of the linkage bracket 14 and the linkage component 3. During the rotation of the two-way screw rod 31, the threaded sleeve 32 can move in the synchronous direction, so that the relative rotation between the connecting rod bases 1 can be controlled, and the two-way screw rod 3 can be fixed with the outer walls of the clamping rod 2. The connecting rod 1 is fixed by the linkage base 34 in cooperation with the annular groove 321 and the limiting bracket 33. The rotating assembly 4 controls the rotation of the bidirectional screw rod 31. The rotating rod 41 is installed at one end of the bidirectional screw rod 31. Since it is linked with the rotating rod 41 through the handle protrusion 44, the bidirectional screw rod 31 rotates synchronously when the rotating handle 43 is rotated. When the annular limiting strip 46 engages with the protrusion on the limiting bracket 33, the bidirectional screw rod 31 is limited in rotation. When it is necessary to control the relative rotation of the connecting rod base 1, it is necessary to pull the rotating handle 43 outward to overcome the elastic force of the spring 45 between the limiting circular plate 42 and the rotating handle 43, so that the annular limiting strip 46 is disengaged from the protrusion.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention as claimed.
