[0020] The following will be combined with the 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.

[0021] See also Figure 1-5 The utility model provides a technical solution: a center pointer movement of a central tourbillon, including a movement body 1 and an adjusting rod 4. Rubber right-angle clamps 2 are sleeved on the upper and lower edges of the movement body 1. A countersunk hole 203 is opened in the rubber right-angle clamp 2. A connecting stud 3 is inserted into the countersunk hole 203. One end of the stem of the movement body 1 is fixedly connected to a first connecting disk 102, and the other side of the first connecting disk 102 is fixedly connected to a first clamping block 103. One end of the adjusting rod 4 is fixedly connected to a second connecting disk 401, and the other side of the second connecting disk 401 is fixedly connected to a second clamping block 402. The second clamping block 402 cooperates with the second connecting disk 401.

[0022] In this embodiment, two rubber right-angle snap rings 2 are respectively put on the upper and lower edges of the movement body 1, and the two rubber right-angle snap rings 2 are connected together by connecting studs 3, thereby fixing the rubber right-angle snap rings 2 to the movement body 1. The rubber right-angle snap rings 2 are made of rubber material as a whole. After the movement body 1 is placed inside the watch case, the rubber right-angle snap rings 2 will replace the movement body 1 to contact the watch case, and the rubber right-angle snap rings 2 are padded between the movement body 1 and the watch case. The characteristics of the rubber material of the rubber right-angle snap rings 2 can provide a certain buffer for the movement body 1 when the watch case is hit. This reduces the impact on the movement body 1 and provides certain protection for the movement body 1. The adjusting rod 4 is rotatably installed on the watch case, and the second clamping block 402 cooperates with the first clamping block 103. When the adjusting rod 4 rotates to drive the second clamping block 402 to rotate, the second clamping block 402 will drive the first clamping block 103 to rotate, and then drive the stem of the movement body 1 to rotate for adjustment. At the same time, the adjusting rod 4 is not directly connected to the stem of the movement body 1. Due to the buffering of the rubber right-angle clamping ring 2 in the movement body 1, it can shake inside the watch case to reduce the impact force. The non-direct connection method can avoid bending and deformation of the adjusting rod 4.

[0023] Among them, in order to achieve the purpose of preventing the angle of the movement body 1 from changing, the present device adopts the following technical solution: a limit groove 101 is provided on the outer wall of the movement body 1, a first limit protrusion 201 is fixedly connected to the inner wall of the rubber right-angle snap ring 2, the first limit protrusion 201 cooperates with the limit groove 101, a second limit protrusion 202 is fixedly connected to the outer wall around the rubber right-angle snap ring 2, and a fixing nut 301 is threadedly installed on the connecting stud 3.

[0024] The limiting groove 101 cooperates with the first limiting protrusion 201 to prevent the movement body 1 from rotating relative to the rubber right-angle retaining ring 2, causing the angle of the movement body 1 to change. The second limiting protrusion 202 cooperates with the groove inside the watch case to clamp the rubber right-angle retaining ring 2 inside the watch case, thereby limiting the position of the movement body 1 to prevent the angle of the movement body 1 inside the watch case from changing. The connecting stud 3 passes through the countersunk hole 203 and screws on the fixing nut 301 to connect the two rubber right-angle retaining rings 2 together.

[0025] In order to achieve the purpose of rotating the adjusting rod 4 on the watch case, the present device adopts the following technical solution: the other end of the adjusting rod 4 is fixedly connected with a connecting thread head 404, and the adjusting rod 4 is fixedly connected with a connecting bearing 403.

[0026] The adjusting rod 4 can be rotatably mounted on the watch case by connecting the bearing 403 , and the connecting thread head 404 is used to connect the knob, which can drive the adjusting rod 4 to rotate.

[0027] The working principle and usage process of the utility model: when using, the device needs to be placed in a suitable position, and the adjusting rod 4 is rotated and installed on the watch case by using the connecting bearing 403, and the connecting stud 3 is passed through the two countersunk holes 203 respectively and the fixing nut 301 is screwed on, and then the two rubber right-angle snap rings 2 are respectively clamped on the upper and lower edges of the movement body 1. At this time, after the movement body 1 is placed into the interior of the watch case, there is a rubber right-angle snap ring 2 between the watch case and the movement body 1 as a cushion. When the watch case is hit, the rubber right-angle snap ring 2 will provide a certain buffer for the movement body 1, thereby reducing the impact on the movement body 1 and providing a certain protection for the movement body 1.

[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
