Description of the invention (1) The present invention relates to a clockwork device element, and more particularly to a mechanism capable of measuring and displaying the working energy stored in a meter. (Please read the precautions on the back before filling this page.) A mechanical watch with a manual winding function must include a winding system, commonly known as a winding device. This device manually transfers energy to the drum tower, which is the watch's Energy accumulator. The winder also has other functions, such as setting or changing the date. By turning the adjusting knob cap head, the adjusting wheel rotates because the driven pinion meshes with the winder pinion, which rotates the ratchet wheel fixed to the drum tower wheel. This is the traditional tower energy storage method. The number of turns of the mainspring / loosespring control is flawless. In order to improve the automaticity of the watch, it is known to use a double drum tower to achieve it. As shown in Swiss Patent C Η 6 1 0 4 6 5, especially shown in Figure 2, the above-mentioned winding principle can be applied to this type of watch. The indication of the automaticity of such a watch has proven to be useful, whether it is a simple watch or a person with a double drum tower, the indication is called ~ Working Degree〃. Such a device has been disclosed in European Patent No. EP 0 5 8 8 499. This device is complex and requires many printed components from the Consumer Cooperatives of the Intellectual Property Office of the Ministry of Economic Affairs and is only suitable for watches with a single simple drum tower. The purpose of the present invention is to provide an operation degree indicating device for a watch with a double drum tower, both of which have manual and automatic winding functions. This purpose is achieved by using an operating degree device with two reeds, one of which is used to wind the mainspring, the other is used to wind the mainspring, a star wheel is integrated with a display device, which is characterized by: The spring barrel includes an upper spring pin that activates an upper spring lever. The upper spring lever rotates the star wheel in the forward direction. This paper size applies the Chinese National Standard (CNS) Α4 specification (210X 297 mm). 527531 A7 B7_ 5. Description of the invention (2) At the same time, the spring barrel includes a loose spring pin that actuates a loose spring lever. The loose spring lever places the star wheel in a reverse rotation, which is positioned by a catch. (#Read the precautions on the back before filling this page) 'First of all, the present invention is applicable to all watches with two reeds. The mechanism with double reeds is characterized in that only one reed rotates when the mainspring is wound, and the other remains stationary. . Conversely, when the mainspring is loosened, the other spring is turned and the first one remains stationary. The highly automatic nature of the oboe system makes it possible to provide a working level indicator. To this end, the existing oboe mechanism has been added with two levers, and the additional operating degree indicating device will affect the reed and the display. Winding is performed by turning the top of the winder to adjust the knob head, and the driven pinion gear engages the winder pinion, which engages the adjustment wheel that drives the ratchet (fixed on the spring barrel shaft). In this way, the spring tube is wound up and performs its primary function, which is to store the energy necessary to operate the watch. A top spring pin is fixed to the top spring barrel. Due to the rotation of the spring barrel, the pin is in contact with a lever. When the lever is tilted to the opposite end, it will actuate the star wheel with the display. The process of printing the mainspring of the bureau's consumer cooperative uses an oscillating block. The rotation of the oscillating block is ensured by the movement of the arm and the combination of pawl and wheels, and the spring is tightened. The reel is wound up and performs its primary function, which is to store the necessary energy while the watch is working. An upper spring pin is fixed on the upper spring barrel. Due to the rotating action of the spring tube, the pin is in contact with a lever, and when the lever is tilted to its opposite end, the star wheel for setting the display will be activated. The mainspring lever and loose mainspring lever use the return spring to disengage the star wheel, allowing the star wheel to move freely when the lever is tilted. A stopper docked on the star wheel ensures that the star wheel is kept under leverage. The paper size applies to the Chinese National Standard (CNS) A4 (210X 297 mm) '"-527531 A7 ---__ _B7 _ V. SUMMARY OF THE INVENTION (3). (Please read the precautions on the back before filling out this page) Each lever is mounted on a rotating shaft, one side of which is fixed on the star gear tooth surface, and the other is opposite to the star gear pin. The invention will be better understood by reading the following detailed description with reference to the attached drawings, where: Figure 1 is an energy storage level indicator and its winding mechanism. Figure 2 shows the energy storage level indicator and its mainspring release mechanism. Figure 3 is a top view of the upper and lower spring mechanisms. Fig. 4 is a sectional view of a two-reel tube in which an energy storage level indicator and its reverse / forward rotation mechanism are stacked. Figure 5 shows the energy storage level indicator, its counterclockwise rotation mechanism and two reeds arranged side by side.

A first lever (referred to as a mainspring lever 4) is installed on a rotating shaft 11 integrated with a bridge (not shown). One end of the lever 4 has a pin 1 4 and the other end is driven with a driving function. One protrusion 1 3. The upper spring rod 6 is held in its rest position by a return spring 6 resting on the pin 12, and the spring function is to guide the upper spring lever 4 back to its rest position, i.e. outside the circumference of the star wheel 3. The impulse of pin 1 4 allows one tooth of the star gear to rotate in the forward direction (winding). The upper spring barrel 1 includes an upper spring pin 9 provided around the spring barrel 1. Each time the spring barrel 1 rotates, the upper spring pin 9 pulls the protrusion 1 of the upper spring lever 4. Pins 1 4 turn into the teeth of star wheel 3. In FIG. 2, the components for winding the mainspring have been removed, and one end of the loose spring lever 5 has a protrusion 15 (shown by a dotted line in the figure), which is loosened by a loose body with the spring barrel 2. Clockwork pin χ 〇 driven. Each time the reed barrel 2 is rotated, the paper size of Songfa is applicable to China National Standard (CNS) A4 (210X 297mm) (Please read the precautions on the back before filling in this page). Printed by the Consumer Cooperative of the Property Bureau A7 B7 V. Description of the invention (5) The pin 5 is tilted around its rotation axis 1 1 and the star wheel 3-teeth is pulled in the reverse direction (loose mainspring). The loose spring lever 5 is held in its rest position by a return spring 7 resting on a pin 16. The spring function is to guide the loose spring lever 5 back to its rest position, that is, outside the circumference of the star wheel 3. The detent 8 functions to hold the star wheel 3 on its indicating device on the one hand, and to participate in tilting on the other hand. In fact, each force of the end of the mainspring pin 14 or the mainspring pin 5 causes the detent 8 to terminate the stroke of one tooth. Fig. 3 is a top view of the one product rod of the entire mechanism and the dagger. The two product rods are installed on the same axis 11 and one of them can observe the dual functions of the mainspring and the mainspring. Fig. 4 is a sectional view of the assembly along a plane determined by the spring tube and the star wheel axis. Fig. 1 The axis of the star wheel 3 is integrated with the operation degree display device (in this example, a scale drum 17). The latter is used as a fixed scale. A counter indicates the degree of operation of the meter. I can observe the two spring barrels which are coaxially arranged and each has a drive pin. The upper spring lever 4 moves on the pin 9 which is integrated with the upper spring barrel 1. On the other hand, the loose spring lever 5 is in contact with the lower spring barrel 2. -The body pin 10 moves. The position of the pin on the spring barrel itself is not important, it can be on the spring barrel, for example exposed on the spring barrel 2 or on the drum, for example on the upper spring barrel 1. FIG. 5 is a variation of the present invention, in which the two reeds are disposed on the same plane. The system of the present invention is also applicable in this example. The main difference is that each lever has its own paper size and applies the Chinese National Standard (CNS) A4 specification (210X 297 mm).
