A socket 4 is provided in the middle of the outer surface of one end of the crown 3, and a clamping hole 5 is provided in the middle of the outer surface of one side of the crown 3, and one end of the clamping hole 5 is connected to the socket 4.

[0027] The second mounting groove 12 is provided at the middle part of the outer surface of one end of the transmission shaft 2 away from the movement body 1, and the second compression spring 13 is located in the second mounting groove 12, and the outer surface of one end of the second compression spring 13 is fixedly connected to one end of the second mounting groove 12, and the outer surface of the other end of the second compression spring 13 is fixedly connected to the outer surface of one end of the extrusion column 14, and one end of the extrusion column 14 extends into the second mounting groove 12; the outer wall of the extrusion column 14 is slidably connected to the second mounting groove 12, and the outer surface of one end of the extrusion column 14 is elastically connected to one end of the second mounting groove 12 through the second compression spring 13; the first mounting groove 8 is provided on the outer surface of the upper end of the transmission shaft 2 near the quick At one end of the disassembly component 7, the first compression spring 9 is located in the first mounting groove 8, the lower end outer surface of the first compression spring 9 is fixedly connected to the lower end of the first mounting groove 8, the upper end outer surface of the first compression spring 9 is fixedly connected to the lower end outer surface of the clamping column 10, and the disassembly limit anti-slip hole 11 is opened on the side of the upper end outer surface of the clamping column 10 close to the quick-release component 7; the outer wall of the clamping column 10 and the first mounting groove 8 are slidably connected, and the lower end outer surface of the clamping column 10 is elastically connected to the bottom of the first mounting groove 8 through the first compression spring 9; the outer wall of one end of the transmission shaft 2 and the socket 4 are plug-in, and the outer wall of the upper part of the clamping column 10 and the clamping hole 5 are clamped.

[0028] It should be noted that the utility model is a watch mechanical movement that is easy to repair. The movement body 1, transmission shaft 2 and crown 3 recorded in the text belong to the prior art, which can be effectively known to the technicians in the relevant technical field, and the details are not repeated here; when the crown 3 is damaged, it needs to be replaced. When installing the crown 3, the crown 3 is inserted into one end of the transmission shaft 2. At this time, the end of the transmission shaft 2 with the quick-release component 7 is inserted into the socket 4, and one end of the crown 3 reaches one side of the clamping column 10 in the connection reinforcement component 6, and then the clamping column 10 is pressed so that the clamping column 10 squeezes the first compression spring 9 along the first installation groove 8, so that the clamping column 10 enters the first installation groove 8, and the crown 3 is continued to be inserted. The extrusion column 14 in the quick-release component 7 contacts and squeezes one end of the socket 4, and the extrusion column 14 squeezes the second compression spring 13 inside the second installation groove 12. When the clamping hole 5 reaches the upper part of the clamping column 10, Due to the reset effect of the first compression spring 9, the upper part of the clamping column 10 is clamped with the clamping hole 5, thereby completing the installation of the crown 3. At this time, the second compression spring 13 is in a compressed state, which can improve the stability of the clamping between the clamping column 10 and the clamping hole 5; during disassembly, the external needle rod is inserted into the disassembly limit anti-slip hole 11 to squeeze the clamping column 10 so that the clamping column 10 is separated from the clamping hole 5, and then the crown 3 is pulled, and one side of the upper part of the clamping column 10 moves into the insertion hole 4. At this time, the needle rod can be pulled out, and then the crown 3 can be pulled out. A disassembly limit anti-slip hole 11 is opened on the side of the outer surface of the upper end of the clamping column 10 close to the quick-release component 7. First, it is to limit the needle rod to avoid relative displacement between the needle rod and the clamping column 10 during disassembly. Secondly, after pressing down the clamping column 10, a part of the crown 3 can be pulled out first, and the upper part of the clamping column 10 can be limited by the insertion hole 4, which is convenient for disassembly.
