自由に着脱が出来ることを目的としたものである。In order to meet the rapidly changing demands of the market, the height from the dial to the hands is being changed and watches are increasingly being designed in a variety of ways. In this case, it is necessary to roughly replace the second hand pinion with a different pinion length, so the assembled movement must be disassembled and reassembled.
In addition, since each movement for each second hand pinion length is prepared in advance, there are disadvantages such as wasted work and the need to manage stocked movements. The present invention has been made in order to eliminate the drawbacks of the prior art as described above, and is aimed at allowing the second hand pinion to be freely attached and detached even after it has been incorporated into the movement.
以下図面に示す実施例によって本発明を詳述する。The present invention will be explained in detail below with reference to embodiments shown in the drawings.
第３図において１は秒針カナであり、二番受５の軸受６

み替えることが出釆る。The bearing 3 having the overhang hole 3a of the second hand kanahozo la is
It is placed horizontally on the support 2b of the first receiver 2, and is held down by an offset pin 4 provided on the first receiver 2. The second hand pinion la passes through a nip hole 3a of the bearing 3, and its tip is pressed downward by a second hand pinion spring 7. Note that the bore hole 3a of the bearing 3
The diameter of the hole is smaller than the diameter of the true lb of the second hand pinion 1, and the clearance of the second hand pinion 1 is ensured by the bearings 3 and 6. Next, to explain the operation of the above mechanism, when rearranging the second hand pinions with different pinion lengths in the state shown in Fig. 3, when the eccentric pin 4 is rotated to the left or right, the bearing 3 and The engagement is disengaged, and the bearing 3 is released in the vertical direction. Therefore, the bearing 3 can be removed from the first bearing 2, and then the second hand pinion 1 can be taken out, and the second hand pinion 1 with a different pinion length can be installed.If the reverse operation is performed, the state shown in Fig. 3 is obtained. It can be returned to. Of course, at this time, it is necessary to attach and detach the second hand pinion spring 7. As described above, the present invention allows the second hand pinion to be attached and detached even after installing another wheel train.
It is possible to rearrange the second hand pinion of different pinion length without disassembling other gear trains.
