The control arm 53 is made of plastic material, and includes a first arm 531 which is elongated and extends from the control member 51 along the first direction D1 and has slight elasticity, a second arm 532 which extends from the first arm 531 to the first adjustment member 41 along the second direction D2, and a protrusion 533 which extends from the second arm 532 to the housing unit 2 and is inserted into the guide groove 25 (see fig. 4).

The reset unit 6 is an extension spring in the first embodiment, and one end of the reset unit is hooked on the first arm 531 of the control arm 53, and the other end is hooked on the back surface of the housing unit 2.

Referring to fig. 5-7, the first embodiment can be changed from a first state as shown in fig. 5, through an intermediate state as shown in fig. 6, to a second state as shown in fig. 7.

The present first embodiment is in the first state as shown in fig. 5 when there is no adjustment date demand. In the first state, when the movement unit 31 is powered, for example, when a battery is installed in the battery slot 21, the first shaft set 321 (see fig. 3) and the second shaft set 322 (see fig. 3) can be driven to rotate to drive the date hand, the hour hand, the minute hand, and the second hand to display different dates and times according to the change of the dates and times. At this time, the second arm portion 532 of the control arm 53 is spaced apart from the first adjuster 41 of the adjuster unit 4, the projection portion 533 of the control arm 53 is positioned on the right side of the guide block 22 and the guide groove 25, and the stopper post 24 of the housing unit 2 is positioned slightly to the left of the middle of the stopper hole 511 of the adjuster 51.

When the user needs to adjust the date during the month change, the user can press or push the pressing block 513 of the control member 51 or pull the operating member 52 with a finger or a rod-shaped object along the first direction D1 to the left to drive the control member 51 and the control arm 53 to move to the left.

In the process that the control arm 53 moves leftward in the drawing along the first direction D1, the protrusion 533 of the control arm 53 moves along the guide slot 25, and drives the first arm 531 and the second arm 532 to move leftward in the drawing, and simultaneously moves upward along the second direction D2 toward the first adjuster 41 of the adjuster unit 4, so that the first embodiment is changed to the intermediate state shown in fig. 6.

In the intermediate state, the protruding portion 533 is located at the upper right of the guide block 22, the second arm portion 532 of the control arm 53 abuts against one of the protruding teeth 413 of the first adjusting member 41, and the reset unit 6 is stretched and deformed.

Further pulling the operating element 52 to the left of the drawing surface, or further pressing the pressing block 513 to further push the control element 51 to the left of the drawing surface, and driving the control arm 53 to move to the left, so that the first embodiment can be further changed to the second state.

During the process that the control arm 53 continues to move leftward, the protrusion 533 will continue to move along the guiding groove 25, and drive the second arm 532 to push one of the protruding teeth 413 of the first adjusting member 41 leftward, so as to drive the first adjusting member 41 to rotate.

When the first adjusting member 41 rotates, the movement unit 31 is driven to rotate the first shaft set 321 (see fig. 3), so that the direction of the date indicator can be changed, and the displayed date can be changed.

In the second state, the protruding portion 533 is located at the left end of the guide slot 25 and approximately above the left of the guide block 22, the reset unit 6 is stretched to the maximum, and the position-limiting post 24 of the housing unit 2 is located at the rightmost side of the position-limiting hole 511 of the control member 51.

When the user releases the control member 51 or the operation member 52, the reset unit 6 releases the elastic force to drive the control member 51 and the control arm 53 to move to the right, so as to return the first embodiment to the first state.

In the process of returning to the first state, since the guide block 22 is obliquely disposed and is bent and protruded upward to the right and is in a state of being high at the left and low at the right in fig. 5, the protrusion 533 will move downward to the right along the guide slot 25 under the pushing of the guide block 22, and drive the second arm 532 to move away from the first adjusting member 41. That is, during the process of returning to the first state, the second arm 532 is spaced from the first adjustment member 41 and does not touch the first adjustment member 41, so that the first adjustment member 41 is not rotated back, i.e., the date is not reversed. When the protrusion 533 crosses the lowest point of the guide 22 and moves to the right of the guide 22 again, the first state is restored.

The user can repeatedly operate the control member 51 to repeatedly move the control member 51 left and right along the first direction D1, i.e. repeatedly switch the first embodiment between the first state and the second state, so that the second arm 532 can push the first adjusting member 41 to rotate a plurality of times. That is, the user can control the angle of the date pointer change by controlling the number of times the control member 51 operates repeatedly, so as to generate the effect of controlling the amount of change (days) in the date section, thereby achieving the purpose of adjusting the amount of dates.

Referring to fig. 8, the second embodiment of the movement device of the present invention is similar to the first embodiment, except that the control arm 53 of the second embodiment further includes a third arm portion 534 protruding toward the first adjustment member 41 along the second direction D2. The third arm portion 534 and the second arm portion 532 are arranged at an interval along the first direction D1, and the third arm portion 534 can push against another protruding tooth 413 of the first adjusting member 41 when the second arm portion 532 pushes against one protruding tooth 413 of the first adjusting member 41. The benefits of this second embodiment are: the control arm 53 can be better ensured to reliably push and drive the first adjusting member 41 to rotate.

In summary, the movement device of the present invention enables a user to operate the control unit 5 along the first direction D1 to drive the control unit 5 to move repeatedly and drive the adjusting unit 4, the movement unit 31 and the crankshaft unit 32 (see fig. 3), so as to generate an effect of adjusting the date, because the user does not need to operate the adjusting unit 4 along the front-back direction D0, the technical problem that the user needs to remove the adjusting unit 4 after being blocked can be solved.
