Description

Technical Field

[0001] This invention relates to the field of mechanical watch winding technology, and more particularly to a watch winding mechanism. Background Technology

[0002] In military applications, clockwork fuses are primarily used as a form of time fuse. A time fuse is a device that uses a timing mechanism to control the detonation or ignition of ammunition. It can trigger an explosion at a specific moment according to a predetermined time interval, thereby achieving a precise strike on the target or an explosive effect under specific conditions. According to search results, time fuses can be classified in many ways, including mechanical (clockwork) time fuses, commonly known as "fuse clocks." Mechanical (clockwork) time fuses require winding.

[0003] Search results:

[0004] A winding mechanism for a clock, disclosed in CN108628139B, includes at least one first accumulator and a second accumulator. The first accumulator is arranged to provide power for a first mechanism, and the second accumulator is arranged to provide power for a second mechanism. The winding mechanism includes a winding stem, a winding pinion, and a sliding pinion. The winding pinion and the sliding pinion are carried by the winding stem and have face gear rings facing each other. The face gear rings are arranged to allow the sliding pinion to drive the winding pinion in both rotational directions of the winding stem. The winding stem and the sliding pinion occupy the same axial winding position.

[0005] The watch winding mechanism, with publication number CN108628142A, is a winding mechanism in a watch with at least two accumulators. These two accumulators are independent or autonomous. One accumulator is the mainspring barrel that powers the basic movement of the watch, and the other accumulator is, for example, the mainspring barrel that powers the automatic mechanism in the watch. The winding mechanism typically includes a winding crown, a winding pinion, and a sliding pinion mounted on the winding crown. The winding stem is configured to occupy at least two axial positions. In the first winding position, rotation of the winding stem in one direction (clockwise) winds the first accumulator (i.e., the first mainspring barrel), and rotation of the winding stem in another direction (counterclockwise) winds the second accumulator (i.e., the second mainspring barrel). In the second time setting position, rotation of the winding stem in both clockwise and counterclockwise directions allows the time of the movement to be set, so that the first and second accumulators cannot be wound regardless of the direction of rotation of the winding stem.

[0006] When the above-mentioned prior art is used

[0007] Firstly, by setting up two accumulators to drive different mechanisms, using only one accumulator to power the movement would affect the watch's lifespan. On the other hand, a second accumulator is set up for the timekeeping mechanism. Since the timekeeping mechanism is not used frequently, the kinetic energy stored in the other accumulator would be wasted. Summary of the Invention

[0008] The purpose of this invention is to provide a winding mechanism for a clock to solve the problems raised in the prior art.

[0009] To achieve the above objectives, the present invention adopts the following technical solution: a winding mechanism for a clock, comprising a clock case, a first accumulator, and a second accumulator. Inside the clock case, a first partition, a second partition, and a third partition are respectively installed according to their distance from the timing dial in ascending order.

The two pulleys are driven by a belt. A double-headed bevel gear that meshes with the upper outer transmission gear ring is rotatably connected to the upper surface of the first-layer partition. The lower part of the first-layer partition... The surface is respectively provided with a lower outer transmission gear ring that meshes with and is rotatably mounted to the other end of the double-headed bevel gear, a connecting arm that is fixedly connected to the inner wall of the lower outer transmission gear ring, a turntable fixed to the bottom end of the pulley that passes through a partition, and a gear column located on one side of the bottom end of the turntable and rotatably connected to a partition. The bottom end of the turntable is fixedly connected to an extended gear ring that meshes with the gear column. Several metal plates are installed at three positions: the bottom end of the turntable, the axial surface of the gear column, and the connecting arm at the center of the lower outer transmission gear ring.

[0012] Preferably, the lower surface of the first layer partition is rotatably connected to a lower inner transmission gear located at the center, a first transmission gear located on the side and meshing with the lower inner transmission gear, and a second transmission gear meshing with the first transmission gear.

[0013] Preferably, the upper surface of the second partition plate is rotatably connected to a first transmission gear, and two second transmission gears and embedded gears that mesh with the first transmission gear and are respectively located below the second transmission gear and the lower inner transmission gear. The surface of the second transmission gear is provided with a transmission insert that is embedded in the bottom end of the second transmission gear. The bottom end of the embedded gear protrudes downward through the second partition plate, and a bevel gear ring is inserted at the extension. The lower surface of the second partition plate is rotatably connected to an upper gear and an insert fixed to the end face of the bevel gear ring on the embedded gear.

[0014] Preferably, the upper surface of the second partition plate is equipped with a minute-jumping spring, a minute-jumping spring, and an hour-jumping spring, respectively, corresponding to the positions of the turntable, gear column, and metal plate on the connecting arm. Pressure sensors are installed at the swing ends of the minute-jumping spring, the minute-jumping spring, and the hour-jumping spring. A sound-generating module connected to the pressure sensor signal passes through the threaded side of the watch case.

[0015] Preferably, a hollowed-out disc is rotatably connected through the lower surface of the second partition plate. One end of the hollowed-out disc extends outward and is fixedly connected to an upper bevel gear block that meshes with the upper gear. A knob is provided through the inner side of the watch case at the position of the hollowed-out disc via a spring sleeve and is inserted into the hollowed-out part of the hollowed-out disc. A hollowed-out column is fixedly connected to the cross-section of the knob inside the watch case.

[0016] Preferably, the central axis of the second accumulator mounted on the three-layer partition extends in the direction of the second layer partition and is also inserted with a bevel gear ring. A transmission column is inserted between the opposite face of the central axis of the second accumulator and the extended end of the second transmission gear. A hollow ring is fixedly connected to the side of the bevel gear ring on the second accumulator. The outer wall of the second accumulator is set with hollows of the same number and position as the hollow ring. The insert is inserted into the hollow ring and the hollow part on the second accumulator.

[0017] Preferably, the transmission mechanism includes a lower swing member rotatably connected to one side of the upper surface of the three-layer partition. The swing side of the lower swing member is fixedly connected to a lower abutment block for supporting the second accumulator, and the pivot point is inserted with a tube penetrating through the second and first layers of partitions.

One swing side of the upper swing member is fixedly connected to an upper abutment block for pressing down the first accumulator, and the other swing side extends downward in a columnar shape and is fitted with a strip extending into the first accumulator. The end of the strip away from the first accumulator is fitted onto the back of the clock face, and the back of the clock face is fitted with a blocking spring for abutting the columnar protrusion of the strip. The swing side of the blocking spring is fixedly connected to an extension spring inserted into the end of the strip away from the first accumulator.

[0018] Preferably, the transmission mechanism further includes an upper insert gear, a lower inner transmission gear, a first transmission gear, a second transmission gear, a transmission insert, a first transmission gear, an embedded gear, a transmission column, a bevel gear ring, and an insert.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] This invention, through the setting of a transmission mechanism, allows the extrusion strip in the first accumulator to move during the release of kinetic energy, thereby causing the upper swinging member to swing. This, in turn, causes the upper contact block to swing out of the space between the first accumulator and the timing dial. Under the action of elastic force, the first accumulator rises until it is no longer in contact with the limiting spring. When the upper swinging member rotates, it synchronously drives the insert to rotate, thereby causing the lower swinging member to drive the lower contact block to rotate out of the space between the second accumulator and the three-layer partition. Under the action of elastic force of the limiting spring, the shell part of the second accumulator is forced to descend to the corresponding limiting spring insertion point. At the same time, when the insert is not inserted into the shell part of the second accumulator, the power can be provided by the release of the second accumulator.

[0021] This invention, by setting up a swashplate, a minute swashplate, and a time swashplate, when the metal plates on the turntable, gear column, and connecting arm rotate past their initial positions, will come into contact with the swinging edges of the corresponding swashplate, minute swashplate, and time swashplate. When they come into contact, the pressure sensors installed on the swashplate, minute swashplate, and time swashplate will generate pressure readings, which will allow personnel to determine the actual triggering time of the fuse based on the frequency of the generated readings.

Detailed Implementation

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Please see Figure 1-14 This invention provides a technical solution: a winding mechanism for a clock, comprising a clock case 1, a first accumulator 40, and a second accumulator 7. Further explanation: both the first accumulator 40 and the second accumulator 7 are mainspring barrels found in existing mechanical watches. Inside the clock case 1, in order of distance from the chronograph dial, there are three layers of partitions: a first layer of partition 4, a second layer of partition 5, and a third layer of partition 6. The other end of the central axis of the first accumulator 40 extends outward and connects to the second hand of the clock. The second, hour, and minute hands of the clock are adjusted according to a known structure.

[0040] A partition 4 has an upper insert gear 30 rotatably connected to the center of the first accumulator 40, which is inserted into the central shaft. An upper inner transmission gear ring 31, meshing with the upper insert gear 30, and an upper outer transmission gear ring 15, meshing with the upper inner transmission gear ring 31, are rotatably connected. Two pulleys 33, respectively fixed to the center of the upper inner transmission gear ring 31 and rotatably connected to the partition 4 via bearings, are also present. The two pulleys 33 are driven by a belt. Additional notes: The upper insert gear 30, upper inner transmission gear ring 31, and upper outer transmission gear ring 15 are provided. The circumference exists in a certain proportion: for every one revolution of the upper insert gear 30, the upper inner transmission gear ring 31 rotates one-sixtieth of a revolution; and for every one revolution of the upper inner transmission gear ring 31, the upper outer transmission gear ring 15 rotates one-twenty-fourth of a revolution. That is, when the first accumulator 40 drives the watch's second hand and the upper insert gear 30 to rotate one revolution for sixty seconds, the upper inner transmission gear ring 31 rotates one-sixtieth of a revolution, which is one minute. One revolution of the upper inner transmission gear ring 31 represents sixty minutes, and one-twenty-fourth of a revolution of the upper outer transmission gear ring 15 represents one hour. To further supplement, such as... Figure 4 As shown, the belt drive ensures that the pulley 33 rotating on the first-layer partition 4 maintains the same rotational speed as the upper inner transmission gear ring 31. A double-headed bevel gear 41, meshing with the upper outer transmission gear ring 15, is rotatably connected through the upper surface of the first-layer partition 4. A lower outer transmission gear ring 34, meshing with the other end of the double-headed bevel gear 41 and rotatably mounted, and a connecting arm 36, fixedly connected to the inner wall of the lower outer transmission gear ring 34, are respectively provided on the lower surface of the first-layer partition 4. (Supplementary explanation: ...) Figure 12 As shown, by changing the shape of the opposite end faces of the upper outer transmission gear ring 15 and the lower outer transmission gear ring 34 to a bevel gear ring shape, and the double-headed bevel gear 41 is installed on both the upper and lower surfaces of the partition plate 4, which are bevel gears meshing with the bevel gear ring, when the upper outer transmission gear ring 15 rotates, the meshing double-headed bevel gear 41 can rotate, and then the lower outer transmission gear ring 34 can rotate through the rotation of the double-headed bevel gear 41. In addition, the upper outer transmission gear ring 15 and the lower outer transmission gear ring 34 have the same dimensions, so it can be ensured that the upper outer transmission gear ring 15 and the lower outer transmission gear ring 34 maintain the same speed, thereby ensuring that the connecting arm 36 maintains the same speed as the upper outer transmission gear ring 15.

[0041] A turntable 32 is fixed to the bottom end of a pulley 33 that passes through a partition 4, and a gear column 17 is located on one side of the bottom end of the turntable 32 and rotatably connected to the partition 4. An extended gear ring 39 that meshes with the gear column 17 is fixedly connected to the bottom end of the turntable 32. Several annularly arranged metal plates 37 are installed at three positions: the bottom end of the turntable 32, the axial surface of the gear column 17, and the center of the lower outer transmission gear ring 34 on the connecting arm 36. Note that the turntable 32 maintains the same rotational speed as the pulley 33, meaning the turntable 32 maintains the same rotational speed as the upper inner transmission gear ring 31. Additionally, as... Figure 10 As shown, six metal plates 37 are provided on the turntable 32. These six metal plates 37 divide the bearing of the extended gear ring 39 into six equal parts, and the arc length of each part of the extended gear ring 39 is equal to the circumference of the gear column 17. Ten metal plates 37 are provided on the gear column 17. In actual use, when the upper inner drive gear ring 31 rotates 36 / 60, it represents the time position indicated by the minute hand at 36 minutes. The upper inner drive gear ring 31 rotates 216 degrees, meaning the turntable 32 also rotates 216 degrees. Because the six metal plates 37 on the turntable 32 are spaced 60 degrees apart, when the turntable 32 rotates 216 degrees, three of the metal plates 37 on the turntable 32 pass through the initial position. After passing through the initial position, the three metal plates 37 on the turntable 32 will rotate another 36 degrees before contacting the fourth metal plate 37, because the extended gear ring 39 on the turntable 32 meshes with the gear column 17. The gear column 17 is connected, and since its circumference is equal to one-sixth of the bearing of the turntable 32, when it rotates 36 degrees, the gear column 17 rotates 216 degrees. Since there are 10 metal plates 37 on the gear column 17, with a spacing of 36 units between adjacent plates, six metal plates 37 on the gear column 17 will pass through the initial position. This means the number of metal plates 37 passing through the turntable 32 represents the tens digit of minutes, and the metal plates 37 on the gear column 17 represent the units digit of minutes. Combining this with the previous supplementary explanation, when the upper inner drive gear ring 31 rotates one revolution representing sixty minutes, the upper outer drive gear ring 15 rotates one twenty-fourth revolution. Correspondingly, there are 24 metal plates 37 on the connecting arm 36. Therefore, when the upper outer drive gear ring 15 rotates one twenty-fourth revolution, one metal plate 37 on the connecting arm 36 will move through the initial position, representing the hours in time.

[0042] The lower surface of the partition plate 4 is rotatably connected to a lower inner drive gear 35 located at the center, a first drive gear 16 located on the side and meshing with the lower inner drive gear 35, and a second drive gear 29 meshing with the first drive gear 16. To further explain, the top of the lower inner drive gear 35 extends upward and is fixed to the bottom of the upper insert gear 30. Therefore, rotation of the upper insert gear 30 will drive the lower inner drive gear 35 to rotate, thereby causing the first drive gear 16 to rotate, and subsequently the second drive gear 29 to rotate.

[0043] The upper surface of the second-layer partition 5 is rotatably connected to a first transmission gear 10, and two second transmission gears 11 and embedded gears 14, which mesh with the first transmission gear 10 and are located below the second transmission gear 29 and the lower inner transmission gear 35, respectively. A transmission pin 12 is inserted through the surface of the second transmission gear 11 and is embedded in the bottom end of the second transmission gear 29. To further explain, the transmission pin 12 enables the second transmission gear 29 to drive the second transmission gear 11 to rotate, which in turn drives the first transmission gear 10 to rotate, thereby rotating the embedded gear 14. Furthermore, the first transmission gear 10 and the first transmission gear 16, the second transmission gear 29 and the second transmission gear 11, and the lower inner transmission gear 35 and the embedded gear 14 have the same number of teeth, diameter, and other dimensions, thus ensuring that the embedded gear 14 and the lower inner transmission gear 35 maintain the same rotational speed.

[0044] The bottom end of the embedded gear 14 protrudes downwards, penetrating the second partition 5, and a bevel gear ring 28 is inserted at the extension. An upper gear 43 is rotatably connected to one side of the lower surface of the second partition 5. Further explanation: the side of the bevel gear ring 28 mounted on the embedded gear 14 is machined to have a straight tooth surface. This straight tooth surface meshes with the upper gear 43, allowing the upper gear 43 to rotate and drive the upper bevel gear ring 28 to rotate.

[0045] Furthermore, the clock case 1 also includes a striking mechanism. On the upper surface of the second-layer partition 5, corresponding to the positions of the metal plate 37 on the turntable 32, gear column 17, and connecting arm 36, respectively, are installed minute-jumping springs 19, minute-jumping springs 18, and hour-jumping springs 13. Pressure sensors 42 are installed on the swinging ends of the minute-jumping springs 19, 18, and 13. A sound-generating module 2, connected to the pressure sensors 42, is threaded through the side of the clock case 1. Additional information: When the turntable 32, gear column 17, and connecting arm 36 rotate past their initial positions, they will contact the swinging edges of the corresponding minute-jumping springs 19, 18, and 13. When activated, the pressure sensors 42 mounted on the minute-operated spring 19, minute-operated spring 18, and hour-operated spring 13 will generate pressure readings. The pressure sensors 42 can be selected from the SGWF series thin-film miniature pressure gauges. The sound module 2 can be the commercially available Netsol Parallel STT-MRAM chip S3R1016, used to collect the usage frequency of the pressure sensors 42 at different locations. The pressure sensors 42 on the minute-operated spring 19, minute-operated spring 18, and hour-operated spring 13 cycle with periods of 6, 10, and 24, respectively. Alternatively, the sound module 2 can be a button or an ultra-thin internal magnetic speaker voice module (Φ36*6.8H mm). During use, the button is used to activate the voice module to announce the usage frequency of the pressure sensors 42 at different locations collected by the chip, facilitating timekeeping.

[0046] The insert 38 is fixed to the end face of the bevel gear ring 28 on the embedded gear 14. A skeletonized disc 45 is rotatably connected through the lower surface of the second-layer partition 5. One end of the skeletonized disc 45 extends outward and is fixedly connected to an upper bevel gear block 44 that meshes with the upper gear 43. A knob 3 is spring-loaded and inserted into the skeletonized part of the skeletonized disc 45 at the position of the skeletonized disc 45 on the inner side of the watch case 1. A skeletonized column 46 is fixedly connected to the cross section of the knob 3 inside the watch case 1. It should be noted that the number of skeletonized parts of the skeletonized disc 45 and the number of columns on the skeletonized column 46 are both multiples of 10. Therefore, when the skeletonized column 46 is not in contact with the skeletonized disc 45, the upper gear 43 rotates with the rotation of the bevel gear ring 28 on the embedded gear 14. In addition, the edge of the end face of the upper gear 43 is also set in the shape of a bevel gear ring, so that when the upper gear 43 rotates, the upper bevel gear block 44 can drive the skeletonized disc 45. 5. Independent rotation, and because the rotation gap is fixed, it ensures that the hollow column 46 can always be aligned with the hollow disk 45. Therefore, during winding, pressing the knob 3 inserts the hollow column 46 into the hollow disk 45, and then rotating the knob 3 causes the hollow column 46 to drive the hollow disk 45 to rotate, which in turn rotates the winding gear 43, thereby achieving the reverse rotation of the bevel gear ring 28 to achieve winding: The central axis of the second accumulator 7, which is mounted on the three-layer partition 6, extends in the direction of the second-layer partition 5 and is also connected to the bevel gear ring 28. A transmission column 48 is inserted between the central axis of the second accumulator 7 and the opposite face of the extended end of the second transmission gear 11, and a hollow ring 47 is fixedly connected to the side of the bevel gear ring 28 on the second accumulator 7. The outer wall of the second accumulator 7 is set with the same number and position of hollows as the hollow ring 47, and the insert 38 is inserted into the hollow ring 47 and the hollow part on the second accumulator 7. Supplementary explanation: Figure 11 and Figure 14As shown, because the insert 38 passes through the hollow ring 47 and the surface of the second accumulator 7, the central shaft inside the casing of the second accumulator 7 cannot rotate freely. Furthermore, as shown in the figure, the relative position of the first accumulator 40 and the back of the watch case 1 is fixed, while the relative position of the first accumulator 40 and the three-layer partition 6 is movable. That is, when the first accumulator 40 is released, it can drive the upper insert gear 30 to rotate. Combined with the above supplementary explanation, power is transmitted from top to bottom, thus achieving synchronous rotation of the second accumulator 7. When the first accumulator 40 is fully released, the first accumulator 40 and the back of the watch case 1... The relative positions of the surfaces move, while the relative positions of the first accumulator 40 and the three-layer partition 6 are fixed. When the plug-in 38 is not plugged into the outer shell of the second accumulator 7, the second accumulator 7 can be used to release power. Under the connection of the transmission column 48, the power can be transmitted from bottom to top, so that the first accumulator 40 can drive the second hand to rotate. The first accumulator 40 and the second accumulator 7 can alternately act on the rotation of the second hand of the watch, extending the service life of the watch. When the first accumulator 40 and the second accumulator 7 are fixed at the same position, the first accumulator 40 and the second accumulator 7 can be wound up by rotating simultaneously through the transmission column 48.

[0047] The transmission mechanism for converting the power of the first accumulator 40 and the second accumulator 7 includes a lower swing member 24 rotatably connected to one side of the upper surface of the three-layer partition 6. The swing side of the lower swing member 24 is fixedly connected to a lower abutment block 25 for supporting the second accumulator 7, and the pivot point is inserted with a plug 20 that penetrates the second layer partition 5 and the first layer partition 4. The top of the plug 20 is inserted with an upper swing member 23 that is rotatably connected to the back of the timing dial of the clock case 1. One swing side of the upper swing member 23 is fixedly connected to... There is an upper contact block 21 for pressing down the first accumulator 40, and another swinging edge extends downward in a columnar shape and is fitted with an insert 26 extending into the first accumulator 40. The end of the insert 26 away from the first accumulator 40 is fitted onto the back of the chronograph dial of the watch case 1, and a blocking spring 22 for abutting the columnar protrusion of the insert 26 is installed on the back of the chronograph dial of the watch case 1. The swinging edge of the blocking spring 22 is fixedly connected to an extension spring 27 inserted into the end of the insert 26 away from the first accumulator 40. Further explanation is provided below. Figure 3 and Figure 9As shown, when the first accumulator 40 is wound, the internal turbine spring is in a contracted state. As the stored energy is released, the spiral spring in the first accumulator 40 will continuously release until it returns to its initial state and adheres to the inner wall of the first accumulator 40. When the first accumulator 40 is released, the spiral spring inside it will squeeze the insert 26, causing the insert 26 to move against the elastic force of the blocking spring 22. By using the other swinging edge of the upper swinging member 23 to fit with the insert 26, the upper swinging member 23 swings, thereby causing the upper abutment block 21 to swing out of the first accumulator 40. Between the device 40 and the timing dial, under the action of elasticity, the first accumulator 40 rises to a point where it is not in contact with the limiting spring 9, that is, the housing part of the first accumulator 40 can rotate. When the upper swing member 23 rotates, it will synchronously drive the insert 20 to rotate, thereby causing the lower swing member 24 to drive the lower abutment block 25 to rotate to disengage from the second accumulator 7 and the three-layer partition 6. Under the action of elasticity of the limiting spring 9, the housing part of the second accumulator 7 is forced to descend to the corresponding limiting spring 9 for insertion. At the same time, when the plug 38 is not inserted into the housing part of the second accumulator 7, the second accumulator 7 can be released.

[0048] The first accumulator 40 is fixed to the back of the chronograph dial of the watch case 1 via an elastic structural component. The second accumulator 7 is also fixed to the upper surface of the three-layer partition 6 via an elastic structural component. The transmission mechanism specifically includes an upper insert gear 30, a lower inner transmission gear 35, a first transmission gear 16, a second transmission gear 11, a transmission insert 12, a first transmission gear 10, an embedded gear 14, a transmission column 48, a bevel gear ring 28, and an insert 38. The elastic structural component is specifically a limiting spring 9 arranged in a ring array on the back of the chronograph dial and the upper surface of the three-layer partition 6. One side of the inner wall of the limiting spring 9 is convex. The bottom edge of the outer wall of the first accumulator 40 is hollowed out, and the outer wall of the second accumulator 7 is fixedly connected to a limiting toothed ring 8. The number of hollowed-out areas and the number of teeth of the limiting toothed ring 8 are both multiples of 12. (Further explanation follows.) Figure 3 and Figure 8 As shown, the initial state of the limiting spring 9 is slightly tilted, and the limiting spring 9 has protrusions near the timing dial and the three-layer partition 6. These protrusions engage with the teeth of the limiting ring 8 on the surface of the first accumulator 40 and the second accumulator 7, thus locking either the first accumulator 40 or the second accumulator 7. In actual use, after the first accumulator 40 has released its kinetic energy, it rises to the active state, while the second accumulator 7 descends from the active state to the fixed state. The watch continues to operate by releasing energy from the second accumulator 7. After the kinetic energy inside the second accumulator 7 has been released, as... Figure 3As shown, the rotation point of the lower swing member 24 extends to the bottom edge of the three-layer partition 6. Therefore, after the second accumulator 7 has finished rotating and winding, the lower swing member 24 can be rotated and reset by rotating the extended end of the lower swing member 24. Under the driving action of the insert 20, the upper swing member 23 can be rotated and reset, thereby allowing the upper contact block 21 to be reinserted between the timing disc and the first accumulator 40. That is, the first accumulator 40 is restored to the fixed state, and the second accumulator 7 is restored to the active state. Therefore, by rotating the knob 3, the first accumulator 40 can be wound under the transmission action of the transmission mechanism.

[0049] The device's operation and working principle are as follows: When the mainsprings in the first accumulator 40 and the second accumulator 7 are wound tightly, and the upper contact block 21 is located between the first accumulator 40 and the timing dial, and the lower contact block 25 is located between the three-layer partition 6 and the second accumulator 7, the housing of the first accumulator 40 is in a fixed state, while the housing of the second accumulator 7 is in a movable state. The openwork on the surface of the second accumulator 7 is inserted into the insert 38. Therefore, the rotation of the mainspring in the first accumulator 40 releases energy, driving the second hand of the clock. Under the transmission mechanism, the second accumulator 7 rotates simultaneously. During the release of kinetic energy from the first accumulator 40, the spiral spring in the first accumulator 40 continuously releases until it returns to its initial state, adhering to the inner wall of the first accumulator 40. Furthermore, during the release, the spiral spring inside the first accumulator 40 compresses the insert 26. This causes the insert 26 to move against the elastic force of the blocking spring 22. By using the other swinging edge of the upper swinging member 23 to fit with the insert 26, the upper swinging member 23 swings, thereby causing the upper abutment block 21 to swing out of the space between the first accumulator 40 and the timing dial. Under the action of the elastic force, the first accumulator 40 rises until it is no longer in contact with the limiting spring 9, that is, the shell part of the first accumulator 40 can rotate. When the upper swinging member 23 rotates, it will drive the insert 20 to rotate synchronously, thereby causing the lower swinging member 24 to drive the lower abutment block 25 to rotate out of the space between the second accumulator 7 and the three-layer partition 6. Under the action of the elastic force of the limiting spring 9, the shell part of the second accumulator 7 is forced to descend to the corresponding limiting spring 9 for insertion. At the same time, when the insert 38 is not inserted into the shell part of the second accumulator 7, the second accumulator 7 can be used to release power.
