[0001] This application claims priority to Chinese patent application number 202410031191.1 and application number January 9, 2024, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present invention relates to the field of low-voltage electrical appliances, and in particular to an operating mechanism and a switching electrical appliance comprising the operating mechanism. Background Art

[0003] Switching electrical appliances are used to close and open circuits. They include an operating mechanism and at least one switching unit. The operating mechanism is transmission-connected to the moving contact mechanism of the switching unit, driving the moving contact mechanism to rotate and close and open the corresponding static contact. The electrical performance of the switching electrical appliance is closely related to the opening distance after the moving contact mechanism and the static contact are disconnected.

[0004] The operating mechanism of the existing switching electrical appliance has an energy storage spring with one end fixed and the other end being a movable end connected to the main shaft to complete energy storage and release. When the energy storage spring releases energy, it drives the main shaft to rotate, and the main shaft drives the moving contact mechanism to rotate through the output shaft. This method results in a limited rotation angle of the output shaft, which results in a smaller opening distance between the moving contact mechanism and the static contact after disconnection, affecting the electrical performance improvement of the switching device.

[0005] In addition, the operating mechanism of the existing switch electrical appliance occupies a large space as a whole.

[0006] In addition, the operating mechanism of the existing switch electrical appliance has a single operating method, which will limit the application scenarios of the switch electrical appliance.

[0077] The following embodiments are combined with the accompanying drawings to further illustrate the specific implementation of the switch device of the present invention. The switch device of the present invention is not limited to the description of the following embodiments.

[0078] As shown in FIG1-19, an embodiment of the switch electrical apparatus of the present invention is shown. The electrical switch of this embodiment is preferably an isolating switch, which includes an operating mechanism o and at least one group of switch units p. The switch unit p includes a unit housing 9 and a contact system disposed within the unit housing 9. The contact system includes a movable contact mechanism m and a static contact that are used in conjunction with each other. The movable contact mechanism m is rotatably disposed. The operating mechanism o is transmission-connected to the movable contact mechanism m of the switch unit p to drive the contact systems of each switch unit p to close and open synchronously, that is, to drive the isolating switch to close and open. The operating mechanism o and the switch unit p are arranged side by side along the rotation axis of the movable contact mechanism m. Furthermore, the isolating switch includes multiple groups of switch units p, each of which is arranged side by side along the rotation axis of the movable contact mechanism m and is synchronously closed and opened under the drive of the operating mechanism o.

[0079] Specifically, the moving contact mechanism m is rotatably arranged around the axis o2-o2, the operating mechanism o and the switch unit p are arranged side by side along the axis o2-o2, and the switch units p are also arranged side by side along the axis o2-o2.

[0080] As shown in FIG1-19, it is an embodiment of the operating mechanism o.

[0081] As shown in Figures 1-3, 5-8, and 16, the operating mechanism o of the first embodiment includes a mechanism housing 1 and an operating shaft 2 and an energy storage transmission assembly a arranged in the mechanism housing 1; the operating shaft 2 is driven by an external force to reciprocate to switch between the open position and the closed position; the energy storage transmission assembly a includes a connecting rod 5 that reciprocates around the axis o2-o2 to switch between the third position and the fourth position and is used to be connected to the moving contact mechanism m of the switching electrical appliance, an energy storage shaft s that reciprocates around the axis o2-o2 to switch between the first position and the second position, and a spring 6 whose two ends are respectively connected to the connecting rod 5 and the energy storage shaft s for rotation, the connecting rod 5 and the energy storage shaft s are coaxially arranged for rotation, and the energy storage shaft s is driven by the operating shaft 2 to rotate; when the energy storage shaft s switches positions, the energy storage shaft s drives the spring 6 to store energy first and then release energy, the connecting rod 5 remains stationary before the spring 6 starts to release energy, and the spring 6 releases energy and drives the energy storage shaft s and the connecting rod 5 to rotate in opposite directions respectively.

[0082] Specifically, the connecting rod 5 and the energy storage shaft s are coaxially rotatable, with both rotating axes being axis o2-o2. The connecting rod 5 has two working positions, namely a third position and a fourth position. The connecting rod 5 rotates about axis o2-o2 and switches between the third and fourth positions by reciprocating rotation. The connecting rod 5 is also used to be transmission-connected to the moving contact mechanism m of the switch electrical appliance to drive the moving contact mechanism m to rotate to close and open with the corresponding static contact. The energy storage shaft s has two working positions, namely a first position and a second position. The energy storage shaft s rotates about axis o2-o2 and switches between the first position and the second position by reciprocating rotation. The operating shaft 2 is driven by an external force to reciprocate, thereby driving the energy storage shaft s to reciprocate, so that the energy storage shaft s switches between its two working positions. The operating mechanism. When performing the opening or closing operation, the operating shaft 2 is driven by an external force (the external force can come from the user's manual operation or from the electric drive mechanism) to move, and at the same time, the operating shaft 2 drives the energy storage shaft s to rotate from one working position to another working position (the energy storage shaft s rotates from the first position to the second position or from the second position to the first position), that is, the operating shaft 2 drives the energy storage shaft s to rotate and switch the working position. During the rotation process, the energy storage shaft s first drives the spring 6 to move to the maximum energy storage position (as shown in part (2) of Figure 16) to complete the energy storage of the spring 6 (as shown in part (1)-(2) of Figure 16, during the process of the energy storage shaft s driving the spring 6 to store energy, the end of the spring 6 connected to the energy storage shaft s makes a circular motion around the axis o2-o2, and the end of the spring 6 connected to the connecting rod 5 remains stationary), and then the energy storage shaft s drives the spring 6 to cross the maximum energy storage position, and then After that, the spring 6 starts to release energy. The energy released by the spring 6 drives the energy storage shaft s to continue rotating in the original rotation direction while driving the connecting rod 5 to rotate in the opposite direction to the energy storage shaft s until the energy storage shaft s and the connecting rod 5 complete the position switching (as shown in parts (2)-(3) of Figure 16, during the energy release process of the spring 6, the end of the spring 6 connected to the energy storage shaft s makes a circular motion around the axis o2-o2 along the rotation direction of the energy storage shaft s, and the end of the spring 6 connected to the connecting rod 5 makes a circular motion around the axis o2-o2 along the rotation direction of the connecting rod 5, that is, during the energy release process, both ends of the spring 6 make a circular motion around the axis o2-o2 and the motion directions are opposite); during the time period between the moment when the operating shaft 2 drives the energy storage shaft s to start rotating and the moment when the operating shaft 2 drives the spring 6 to cross the maximum energy storage position through the energy storage shaft s, the connecting rod 5 remains stationary and will not rotate due to the action of the energy storage shaft s and the spring 6. Furthermore, the opening position, the first position and the third position correspond to each other, and the closing position, the second position and the fourth position correspond to each other, that is: the operating mechanism.In the open state, the operating shaft 2 is in the open position, the energy storage shaft s is in the first position, and the connecting rod 5 is in the third position; when the operating mechanism o is in the closed state, the operating shaft 2 is in the closed position, the energy storage shaft s is in the second position, and the connecting rod 5 is in the fourth position; that is, the operating shaft 2 is driven by an external force to rotate from the open position to the closed position, causing the operating mechanism o to perform the closing operation and switch from the open state to the closed state; the operating shaft 2 is driven by an external force to rotate from the closed position to the open position, causing the operating mechanism o to perform the opening operation and switch from the closed state to the open state.

[0083] Compared to existing operating mechanisms in which one end of the energy storage spring is fixed and the other end performs circular motion to store and release energy, the operating mechanism o of this embodiment has a spring 6 that is movable at both ends. This allows the operating mechanism of this embodiment to achieve a significant increase in the rotation angle of the connecting rod 5 while maintaining a spatial dimension similar to that of existing operating mechanisms. This significantly increases the final gap between the movable contact mechanism, which is connected to the connecting rod 5, and the corresponding static contact (i.e., the disconnection gap between the movable contact and the static contact), thereby significantly improving the disconnection performance and electrical performance of the switching electrical appliance using the operating mechanism o of this embodiment, particularly for interrupting high-current DC circuits. Furthermore, the operating mechanism o of this embodiment has a simple structure and a compact layout, requiring less space.

[0084] Further, as shown in Figures 3, 6, 13, and 15, when the spring 6 acts on the energy storage shaft s to establish a first limiting fit with the mechanism housing 1 and keep the energy storage shaft s in the first position, the energy storage shaft s has a tendency to rotate in the second direction under the action of the spring 6; when the spring 6 acts on the energy storage shaft s to establish a second limiting fit with the mechanism housing 1 and keep the energy storage shaft s in the second position, the energy storage shaft s has a tendency to rotate in the first direction under the action of the spring 6; the energy storage shaft s rotates and switches along the first direction (or the second direction) in the first position (or the second position) To the second position (or the first position); when the spring 6 acts on the connecting rod 5 to establish a third limit fit with the mechanism housing 1 and keep the connecting rod 5 in the third position, the connecting rod 5 has a tendency to rotate in the first direction under the action of the spring 6; when the spring 6 acts on the connecting rod 5 to establish a fourth limit fit with the mechanism housing 1 and keep the connecting rod 5 in the fourth position, the connecting rod 5 has a tendency to rotate in the second direction under the action of the spring 6; the connecting rod 5 rotates in the second direction (or the first direction) in the third position (or the fourth position) to switch to the fourth position (or the third position).

[0085] Specifically, when the energy storage shaft s switches from the first position to the second position, the energy storage shaft s rotates along the first direction, the energy storage shaft s drives the spring 6 to move to the maximum energy storage position and beyond the maximum energy storage position, the spring 6 releases energy and drives the energy storage shaft s to continue rotating toward the second position, until the energy storage shaft s establishes a second limit fit with the mechanism housing 1 and limits the energy storage shaft s to the second position; when the energy storage shaft switches from the second position to the first position, the energy storage shaft s rotates along the second direction, the energy storage shaft s drives the spring 6 to move to the maximum energy storage position and beyond the maximum energy storage position, the spring 6 releases energy and drives the energy storage shaft s to continue rotating toward the first position, until the energy storage shaft s cooperates with the first limit fit with the mechanism housing 1 and limits the energy storage shaft s to the first position. When the connecting rod 5 is driven by the spring 6 to switch from the third position to the fourth position, the connecting rod 5 rotates in the second direction, and the spring 6 releases energy to drive the connecting rod 5 to rotate until it establishes a fourth limit fit with the mechanism housing 1 and limits the connecting rod 5 to the fourth position; when the connecting rod 5 is driven by the spring 6 to switch from the fourth position to the third position, the connecting rod 5 rotates in the first direction, and the spring 6 releases energy to drive the connecting rod 5 to rotate until it establishes a third limit fit with the mechanism housing 1 and limits the connecting rod 5 to the third position.

[0086] As shown in Figures 6 and 9, the energy storage transmission assembly a has at least one assembled state; when the energy storage transmission assembly a is in a free state, that is, when the energy storage transmission assembly a is not assembled to the operating mechanism o, the spring 6 acts on the connecting rod 5 and the energy storage shaft s respectively, causing the connecting rod 5 and the energy storage shaft s to have a tendency to rotate relative to each other in opposite directions, so that the connecting rod 5 and the energy storage shaft s limit the relative rotation of the connecting rod 5 and the energy storage shaft s, thereby maintaining the energy storage transmission assembly a in the assembled state. The assembled state of the energy storage transmission assembly a allows the energy storage shaft s, connecting rod 5, and spring 6 of the energy storage transmission assembly a to be pre-assembled together. When applied to the operating mechanism o, they can be assembled into the operating mechanism o as a whole, which helps to reduce the assembly difficulty of the operating mechanism o, simplify the operation, and improve the assembly efficiency. Furthermore, the energy storage transmission assembly a has two assembly states. In both assembly states, the spring 6 acts on the connecting rod 5 and the energy storage shaft s, respectively, causing them to rotate in opposite directions relative to each other. In both assembly states, the energy storage transmission assembly a has a tendency to rotate in opposite directions under the action of the spring 6, and the connecting rod 5 has a tendency to rotate in opposite directions under the action of the spring 6. That is, the two assembly states are respectively a first assembly state and a second assembly state. In the first assembly state, the spring 6 acts on the energy storage shaft s, causing it to rotate in the first direction, and acts on the connecting rod 5, causing it to rotate in the second direction. In the second assembly state, the spring 6 acts on the energy storage shaft s, causing it to rotate in the second direction, and acts on the connecting rod 5, causing it to rotate in the first direction. Furthermore, the operating mechanism. In the closed state and the open state, the energy storage transmission assembly a is in two assembly states, respectively, that is, the operating mechanism. In the closed state, the energy storage transmission component a is in an assembled state, and the energy storage shaft s and the connecting rod 5 are in a limited fit (the two are in a relative position). When the operating mechanism o is in the open state, the energy storage transmission component a is in another assembled state, and the energy storage shaft s and the connecting rod 5 are in a limited fit (the two are in another relative position). In the closed state and the open state, the energy storage shaft s and the connecting rod 5 are in a limited fit to prevent relative rotation, which is beneficial to reducing the impact force of the energy storage shaft s and the connecting rod 5 on the mechanism housing 1, thereby extending the service life of the operating mechanism o. It should be pointed out that in the closed state and the open state, the energy storage shaft s and the connecting rod 5 may not be in a limited fit. In this case, the energy storage shaft s and the connecting rod 5 need to continue to rotate relative to each other by a certain angle to establish a limited fit.

[0087] As shown in Figures 1-3 and 5, the operating shaft 2 rotates about axis o1-o1 to switch between the open position and the closed position. That is, the operating shaft 2 has two working positions, namely the open position and the closed position. The operating shaft 2 is arranged to rotate about axis o1-o1 and switches between the open position and the closed position by reciprocating rotation. Axis o1-o1 and axis o2-o2 are perpendicular to each other. The operating shaft 2 is driven by an external force to reciprocate, thereby driving the energy storage shaft s to reciprocate. Furthermore, axis o1-o1 and axis o2-o2 are coplanar and perpendicular to each other.

[0088] In other embodiments, the operating shaft 2 is configured for linear movement, with the direction of movement of the operating shaft 2 being perpendicular to the axis o2-o2. The operating shaft 2 is driven by an external force to move back and forth linearly, thereby driving the energy storage shaft s to rotate back and forth. Furthermore, the operating shaft 2 and the energy storage shaft s are coupled via a rack and pinion system for transmission. Alternatively, the operating shaft 2 is provided with a shifting portion, and the energy storage shaft s is provided with two corresponding sets of driven portions. The reciprocating movement of the operating shaft 2 causes the shifting portion to press against the two driven portions, causing the energy storage shaft s to rotate back and forth.

[0089] As shown in Figures 2-3, 5-7, and 10, the operating shaft 2 includes an operating shaft driving part 2-1, and the energy storage shaft s includes an energy storage shaft driven part 4-1. The operating shaft 2 is driven by external force to rotate and drives the operating shaft driving part 2-1 to rotate. The operating shaft driving part 2-1 drives the energy storage shaft s to rotate through the energy storage shaft driven part 4-1.

[0090] Specifically, the operating shaft driving part 2-1 includes a driving bevel gear that is rotated around the axis o1-o1, that is, the axis of the driving bevel gear coincides with the axis o1-o1; the energy storage shaft driven part 4-1 includes a driven bevel gear 4-12 that is rotated around the axis o2-o2, that is, the axis of the driven bevel gear 4-12 coincides with the axis o2-o2; the driving bevel gear is engaged with the driven bevel gear 4-12.

[0091] As another embodiment, the operating shaft driving part 2-1 is a toggle block that performs circular motion around the axis o1-o1, and the energy storage shaft driven part 4-1 includes two driven blocks arranged relatively spaced apart, and the toggle block is located between the two driven blocks. The operating shaft 2 is rotated by external force and drives the toggle block to swing, and the toggle block presses the two driven blocks respectively to rotate the energy storage shaft s.

[0092] As another embodiment, the operating shaft 2 and the energy storage shaft s are coupled through a worm gear transmission method. Accordingly, the axis o1-o1 and the axis o2-o2 are not coplanar, and the two are perpendicular to each other only in space.

[0093] As shown in Figures 1-3, 5, and 10, the operating shaft 2 also includes an operating shaft stem 2-0, and the mechanism shell 1 includes a shell operating shaft hole 1-00. The operating shaft stem 2-0 is rotatably inserted into the shell operating shaft hole 1-00 and is used for external force operation to drive the operating shaft 2 to rotate, that is, the external force drives the operating shaft 2 to rotate through the operating shaft stem 2; one end of the operating shaft stem 2-0 is connected to the operating shaft driving part 2-1.

[0094] Furthermore, the other end of the operating shaft 2-0, that is, the end of the operating shaft 2-0 away from the operating shaft driving portion 2-1, protrudes outside the mechanism housing 1 for operation. Of course, the end of the operating shaft 2-0 away from the operating shaft driving portion 2-1 can also be flush with the outer side surface of the mechanism housing 1 or lower than the outer side surface of the mechanism housing 1.

[0095] Furthermore, the free end of the operating shaft 2-0, that is, the end of the operating shaft 2-0 away from the operating shaft driving part 2-1, is provided with an operating shaft socket 2-00; the operating mechanism o also includes an operating handle, which is inserted into the operating shaft hole 2-00 to drive the operating shaft 2 to rotate; the operating shaft 2-0 is preferably also provided with a fixing hole 2-01, which extends radially along the operating shaft 2-0 and intersects with the operating shaft socket 2-00, and a fixing screw is provided in the fixing hole 2-01 and is threadedly connected to it to fix the operating handle and the operating shaft 2-0 together.

[0096] Furthermore, a mechanism shell slot is provided on the inner side wall of the shell operating shaft hole 1-00, and the mechanism shell slot extends along the circumferential direction of the shell operating shaft hole 1-00; the operating shaft stem 2-0 includes a shaft positioning portion 2-02, and the shaft positioning portion 2-02 makes a circular motion around the axis o1-o1 under the drive of the operating shaft stem 2-0, and the shaft positioning portion 2-02 is inserted into the mechanism shell slot to limit the movement of the operating shaft 2 along the axis o1-o1 direction, thereby ensuring the reliable cooperation and transmission of the operating shaft 2 and the energy storage shaft s.

[0097] Furthermore, as shown in Figures 1, 3, 17, and 19, the operating mechanism o of this embodiment also includes an operating shaft positioning member 7 fixedly connected to the mechanism housing 1. The operating shaft positioning member 7 is a metal member and is provided with a positioning member hole. The positioning member hole is coaxially arranged with the operating shaft hole 1-00 of the housing. The inner diameter of the positioning member hole is adapted to the outer diameter of the operating shaft 2. The operating shaft 2 is rotatably inserted into the positioning member hole. The operating shaft positioning member 7 ensures that the operating shaft 2 rotates in the correct posture, prevents the operating shaft 2 from sliding or tilting, and ensures the reliable and stable operation of the operating mechanism o. Furthermore, the operating shaft positioning member 7 is a U-shaped structure. The mechanism housing 1 includes a positioning member mounting platform provided on its outer surface. The operating shaft positioning member 7 is buckled onto the positioning member mounting platform, that is, the positioning member mounting platform is placed in the U-shaped structure of the operating shaft positioning member 7. The positioning member mounting platform is limitedly engaged with a pair of side walls of the U-shaped structure.

[0098] As shown in Figures 1-2, 6, 13, and 17-19, the connecting rod 5 is provided with an output structure that passes through the side wall of the mechanism housing 1 and is used for transmission connection with the movable contact mechanism m of the switch. Furthermore, the output structure is provided by the connecting rod shaft 5o of the connecting rod 5, which will be described in detail below.

[0099] As shown in Figures 1-3, 5-7, and 13-15, the energy storage shaft s and spring 6 are both disposed within the connecting rod 5. Furthermore, the axial ends of the energy storage shaft s are rotatably mounted on the connecting rod 5. The aforementioned layout and assembly relationship design of the energy storage shaft s, connecting rod 5, and spring 6 further enhance the structural compactness of the operating mechanism o of this embodiment and reduce required space.

[0100] It should be pointed out that the energy storage shaft s and the spring 6 do not have to be arranged in the connecting rod 5, and the axial ends of the energy storage shaft s do not have to be rotatably arranged on the connecting rod 5. It is only necessary to satisfy that the energy storage shaft s and the connecting rod 5 are respectively rotatably arranged around the axis o1-o1 and the spring 6 is respectively coordinated with the energy storage shaft s and the connecting rod 5. For example: the axial ends of the energy storage shaft s can be directly rotatably arranged on a pair of side walls of the mechanism housing 1, or the energy storage shaft s is rotatably arranged on a bracket for supporting the energy storage shaft s and the bracket is fixedly arranged on the mechanism housing 1, the spring 6 can be side by side with the connecting rod 5 in the direction of the axis o1-o1, the energy storage shaft s can be arranged side by side with the connecting rod 5 in the direction of the axis o1-o1, or the middle part of the connecting rod 5 can be rotatably sleeved on the energy storage shaft. The above only lists some possible layout methods of the energy storage shaft s, the connecting rod 5, and the spring 6. Those skilled in the art can make other modified designs on the basis of ensuring the action mode and coordination relationship of the energy storage shaft s, the connecting rod 5, and the spring 6, which should all fall within the scope of protection of this application.

[0101] As shown in Figures 1-2 and 13-15, the connecting rod 5 is rotatably mounted on the mechanism housing 1. Furthermore, the connecting rod 5 can be directly rotatably mounted on the mechanism housing 1, for example, the connecting rod 5 is rotatably mounted on a pair of side walls of the mechanism housing 1 via a pair of connecting rod shafts 5o, which will be described in detail below.

[0102] As other embodiments, the connecting rod 5 is indirectly rotatably set on the mechanism housing 1, for example, the connecting rod 5 is rotatably set on a bracket for supporting the connecting rod 5, and the bracket is fixed on the mechanism housing 1; or, the connecting rod 5 is indirectly rotatably set on the mechanism housing 1 through the energy storage shaft s.

[0103] At least one of the two axial ends of the energy storage shaft s passes through the mechanism housing 1 to provide external force operation to drive the energy storage shaft s to rotate.

[0104] Specifically, as shown in Figures 1-2, 6, 13, and 15, the axial ends of the energy storage shaft s respectively pass through a pair of side walls of the mechanism housing 1, allowing external force to operate and drive the energy storage shaft s to rotate. That is, the axial ends of the energy storage shaft s respectively pass through a pair of side walls of the mechanism housing 1, and external force can operate both ends of the energy storage shaft s to drive its rotation. This design of the energy storage shaft s enables the operating mechanism o of the first embodiment to perform opening and closing operations not only via the operating shaft 2 but also via the energy storage shaft s. This allows the user to operate the operating mechanism o of the first embodiment from multiple directions, greatly expanding the application scenarios of the operating mechanism of this embodiment. In actual use scenarios, although both axial ends of the energy storage shaft s can pass through the side walls of the mechanism housing 1 to allow external force operation, after the switch unit p and the operating mechanism o are assembled, one of the axial ends of the energy storage shaft s will inevitably be obstructed by the switch unit p. Depending on actual needs, the energy storage shaft s may only have one axial end pass through a side wall of the mechanism housing 1 to allow external force operation and drive the energy storage shaft s to rotate. When the energy storage shaft s can be driven to rotate in the above manner, the operating shaft 2 can be omitted to further simplify the structure of the operating mechanism o, or more ways and directions of operating the operating mechanism o can be provided without omitting the operating shaft 2.

[0105] Furthermore, as shown in Figures 3, 5, 6-8, and 14, the energy storage transmission assembly a includes two groups of springs 6, which are respectively arranged on both radial sides of the energy storage shaft s, and both ends of each group of springs 6 are respectively connected to the connecting rod 5 and the energy storage shaft s for rotation.

[0106] Specifically, the spring 6 is a linear compression spring, which includes a spring body 60 and a first connecting portion and a second connecting portion respectively connected to the two ends of the spring body 60, the first connecting portion is rotationally connected to the energy storage shaft s, and the second connecting portion is rotationally connected to the connecting rod 5; as shown in part (2) of Figure 16, when the spring 6 is in the maximum energy storage position, the geometric axis of the spring 6 is coplanar with the axis o2-o2, and the two intersect vertically.

[0107] As another embodiment, the spring 6 can also be a torsion spring, whose two ends are respectively connected to the energy storage shaft s and the connecting rod 5 for rotation; when the spring 6 is in the maximum energy storage position, the lines connecting the points of action of the energy storage shaft s and the connecting rod 5 are respectively coplanar with the axis o2-o2, and the two intersect vertically.

[0108] As shown in Figures 1-2, the mechanism housing 1 comprises a front half-shell 1-1 and a rear half-shell 1-2 that are relatively matched. Furthermore, the front half-shell 1-1 and the rear half-shell 1-1 are relatively assembled together along the axis o2-o2.

[0109] The specific assembly structure of the mechanism housing 1, the energy storage shaft s, the connecting rod 5, and the spring 6 as well as their respective specific structures will be described in detail below.

[0110] As shown in Figures 2-3, 5-8, and 13, the connecting rod 5 includes a pair of side walls and a pair of end walls arranged opposite to each other, the pair of side walls are respectively the connecting rod front wall 5-1 and the connecting rod rear wall 5-3, the pair of end walls are respectively the first end wall 5-2 and the second end wall 5-4, the connecting rod front wall 5-1, the first end wall 5-2, the connecting rod rear wall 5-3 and the second end wall 5-4 are connected end to end to form a connecting rod cavity 5c; the energy storage shaft s is arranged in the middle of the connecting rod cavity 5c and its two ends are respectively rotatably arranged on the connecting rod front wall 5-1 and the connecting rod rear wall 5-3; the two springs 6 are respectively arranged at both ends of the connecting rod cavity 5c, and one end of the two springs 6 is rotationally connected to the first end wall 5-2 and the second end wall 5-4 respectively, and the other ends are rotationally connected to the radial ends of the energy storage shaft s, that is, of the two springs 6, one end of one spring 6 is rotationally connected to the first end wall 5-2 and the other end is rotationally connected to one radial end of the energy storage shaft s, and the other end of the other spring 6 is rotationally connected to the second end wall 5-4 and the other end is rotationally connected to the other radial end of the energy storage shaft s.

[0111] Specifically, the connecting rod cavity 5c includes an axial cavity 50c and a spring cavity 51c. The two spring cavities 51c are symmetrically arranged on either side of the axial cavity 50c and communicate therewith. The energy storage shaft s is rotatably disposed within the axial cavity 50c, and the two springs 6 are disposed in the two spring cavities 51c, respectively. Furthermore, in the direction of the axis o2-o2, the width of the axial cavity 50c is greater than the width of the spring cavity 51c, and the ends of the axial cavity 50c protrude beyond the spring cavity 51c.

[0112] Furthermore, the connecting rod 5 is an integrated structure with higher structural strength, which is beneficial to improving the structural stability of the operating mechanism o and reducing the number of parts of the operating mechanism o.

[0113] As another embodiment, the connecting rod 5 may also be a split structure, with the first end wall 5-2 detachably connected to the connecting rod front wall 5-1 and the connecting rod rear wall 5-3, and the second end wall 5-4 detachably connected to the connecting rod front wall 5-1 and the connecting rod rear wall 5-3. This helps to reduce the difficulty of manufacturing the connecting rod 5, but it will increase the number of parts and may also affect the structural strength of the connecting rod 5. For example, the first end wall 5-2 and the second end wall 5-4 may be two metal shafts, each metal shaft having two ends connected to the connecting rod front wall 5-1 and the connecting rod rear wall 5-3, respectively, and the second connecting portion of the spring 6 is rotatably sleeved on the corresponding metal shaft.

[0114] Furthermore, the axial ends of the energy storage shaft s are rotatably mounted on a pair of side walls of the connecting rod 5. Furthermore, each side wall of the connecting rod 5 is provided with a connecting rod shaft hole, the axis of which coincides with the axis o2-o2, and the axial ends of the energy storage shaft s are rotatably mounted within the connecting rod shaft holes of the two side walls. Specifically, the connecting rod shaft hole of the connecting rod front wall 5-1 is the connecting rod front shaft hole 5-1s, and the connecting rod shaft hole of the connecting rod rear wall 5-3 is the connecting rod rear shaft hole 5-3s. The axial ends of the energy storage shaft s are rotatably mounted within the connecting rod front shaft hole 5-1s and the connecting rod rear shaft hole 5-3s, respectively. Furthermore, the connecting rod shaft hole is a through hole.

[0115] Furthermore, the connecting rod 5 also includes a connecting rod shaft 5o, the axis of which coincides with the axis o2-o2, and the two connecting rod shafts 5o are respectively arranged on both axial sides of the connecting rod 5; the mechanism housing 1 also includes two housing output shaft holes 1o respectively arranged on a pair of its side walls, and the two connecting rod shafts 5o are respectively rotatably inserted into the two housing output shaft holes 1o. Furthermore, the two housing output shaft holes 1o are through holes, and both connecting rod shafts 5o can be transmission-connected to the moving contact mechanism m of the switching electrical appliance through the housing output shaft holes 1o. That is, in the direction of the axis o2-o2, the switch unit p of the switching electrical appliance can be arranged on both sides of the operating mechanism o, and the two connecting rod shafts 5 are transmission-connected to the moving contact mechanism m on both sides of the operating mechanism o. Of course, according to actual needs, it is also allowed to arrange the switch unit p on only one side of the operating mechanism o in the direction of the axis o2-o2. The housing output shaft hole 1o corresponding to the switch unit p is a through hole, and the other housing output shaft hole 1o can be a through hole or a blind hole.

[0116] Specifically, the two connecting rod shafts 5o are respectively arranged on the outer side surfaces of the connecting rod front wall 5-1 and the connecting rod rear wall 5-3 (that is, the two side surfaces opposite to each other of the connecting rod front wall 5-1 and the connecting rod rear wall 5-3); the two connecting rod shaft holes respectively pass through the middle of the two connecting rod shafts 5o, and the connecting rod shaft holes and the connecting rod shaft 5o are coaxially arranged; the axial ends of the energy storage shaft s are respectively rotatably arranged in the two connecting rod shaft holes and respectively pass through the two output shaft holes 1o, which are used to provide external force operation to drive the operating shaft s to rotate.

[0117] As another embodiment, the connecting rod shaft 5o of the connecting rod 5 is only used as a structure for realizing the rotation setting of the connecting rod 5, and a structure for being connected to the moving contact mechanism m of the switching electrical appliance is additionally provided. For example, the connecting rod 5 is provided with a driving shaft parallel to the axis o1-o1, and the connecting rod 5 rotates to drive the moving contact mechanism m to rotate through the driving shaft; accordingly, an arc-shaped hole matching the moving trajectory of the driving shaft is provided on the side wall of the mechanism housing 1.

[0118] As another embodiment, the connecting rod shaft 5o of the connecting rod 5 is only used as an output structure for realizing transmission connection between the connecting rod 5 and the moving contact mechanism m, and the connecting rod 5 is provided with other structures for realizing the rotation setting of the connecting rod 5.

[0119] Furthermore, the connecting rod 5 includes a connecting rod spring seat 5-6 disposed on the end wall, the connecting rod spring seat 5-6 having a connecting rod spring slot. The second arm 6-2 of the spring 6 is parallel to the axis o2-o2. The second arm 6-2 of each spring 6 is rotatably disposed within the connecting rod spring slot of the corresponding connecting rod spring seat (5-6). Specifically, the first end wall 5-2 and the second end wall 5-4 of the connecting rod 5 are both provided with a connecting rod spring seat 5-6.

[0120] As shown in Figures 3-8, 11, and 14, the energy storage shaft s also includes a connecting arm 3-10, one end of the spring 6 is rotationally connected to the connecting arm 3-0 and the other end is rotationally connected to the connecting rod 5.

[0121] Specifically, the energy storage shaft s includes two groups of connecting arms 3-0, which are respectively arranged on the radial sides of the energy storage shaft s and are respectively rotatably connected to one end of the two groups of springs 6, and the other ends of the two groups of springs 6 are respectively rotatably connected to the connecting rod 5.

[0122] Furthermore, the connecting arm 3-10 is provided with a connecting hole 3-11, and the connecting hole 3-11 includes a connecting limit hole 3a extending along the axis o2-o2 direction, and a connecting hole inlet 3i arranged on a radial side of the connecting limit hole 3a and connected thereto, and the inner diameter φ1 of the connecting hole limit hole 3a is greater than the width d1 of the connecting hole inlet 3i; the first connecting portion includes a first arm 6-1, the first arm 6-1 is parallel to the axis o2-o2, and includes at least one avoidance surface 6-10, the width d1 of the connecting hole inlet 3i is less than the outer diameter φ2 of the first arm 6-1 ≤ the inner diameter φ1 of the connecting limit hole 3a, and in the direction perpendicular to the avoidance surface 6-10, the cross-sectional width d2 of the first arm 6-1 ≤ the width d1 of the connecting hole inlet 3i; when the spring 6 is assembled with the energy storage shaft s, the first The avoidance surface 6-10 of the arm 6-1 is opposite to the side of the connecting hole interface 3i, so that the first arm 6-1 can enter the connecting hole limit hole 3a through the connecting hole entrance 3i. After the other end of the spring 6 (that is, the second arm 6-2 of the spring 6) is assembled, the first arm 6-1 will rotate relative to the connecting limit hole 3a, so that the avoidance surface 6-10 is staggered with the connecting hole entrance 3i, and during the rotation of the energy storage shaft s, the avoidance surface 6-10 will never be opposite to the side of the connecting hole entrance 3i. Since the outer diameter φ2 of the first arm 6-1 is greater than the width d1 of the connecting hole entrance 3i, it is ensured that the first arm 6-1 will not fall out of the connecting limit hole 3a, thereby ensuring the reliable and stable operation of the operating mechanism o and simplifying the assembly operation of the connecting arm 3-10 and the first arm 6-1. Furthermore, the first connecting portion is a U-shaped structure, which includes a first blocking arm, a first arm 6-1 and a second blocking arm connected in sequence, the first blocking arm and the second blocking arm are opposite to each other, and after the first arm 6-1 and the connecting arm 3-10 are assembled, the first blocking arm and the second blocking arm are respectively located on both sides of the connecting arm 3-10 in the direction of the axis o2-o2.

[0123] Specifically, the first arm 6 - 1 is provided with two avoidance surfaces 6 - 10 , and the two avoidance surfaces 6 - 10 are arranged oppositely at the radial ends of the first arm.

[0124] As another embodiment, the connecting hole 3-11 of the connecting arm 3-10 is a complete through hole, and the first connecting portion of the spring 6 is a U-shaped structure. One end of the first connecting portion is connected to the spring body 6-0 of the spring 6, and the other end is inserted into the connecting hole 3-11, so that the bottom edge of the U-shaped structure of the first connecting portion is placed in the connecting hole 3-11, thereby completing the assembly of the connecting arm 3-10 and the spring 6.

Furthermore, the structural shell 1 includes a shell-blocking energy storage shaft portion 1-0b and a shell-blocking connecting rod portion 1-1b. The shell-blocking energy storage shaft portion 1-0b and the shell-blocking connecting rod portion 1-1b are located on both sides of the energy storage transmission assembly a and on both sides of the energy storage shaft s in the radial direction of the energy storage shaft s. The two energy storage shaft blocking surfaces 1-00b are both provided on the shell-blocking energy storage shaft portion 1-0b, and the two connecting rod blocking surfaces 1-10b are both provided on the shell-blocking connecting rod portion 1-1b.

The two sub-blocking portions are relatively assembled together along the axis o2-o2 and respectively cooperate with a pair of side walls of the connecting rod 5.

[0127] Furthermore, as shown in Figures 2-9 and 12, the energy storage shaft s includes an energy storage shaft matching portion 4-11, and the energy storage shaft matching portion 4-11 is respectively matched with the first stop surface and the second stop surface.

[0128] Specifically, the energy storage shaft s includes two energy storage shaft matching parts 4-11, which are arranged at intervals along the axial direction of the energy storage shaft s and are respectively the first energy storage shaft matching part and the second energy storage shaft matching part. The first energy storage shaft matching part is used to match with the first stop surface, and the second energy storage shaft matching part is used to match with the second stop surface. Further, each of the energy storage shaft matching parts 4-11 is provided with a first matching surface, which is used to match with the two first stop surfaces. The two ends of the connecting rod 5 are respectively matched with the two connecting rod stop surfaces 1-10b, and the connecting rod 5 is respectively limited in the third position and the fourth position. Further, the two ends of the side edge of the side wall of the connecting rod 5 are respectively matched with the two connecting rod stop surfaces 1-10b.

[0129] As shown in Figures 2-3, 6, and 9, the connecting rod 5 also includes an assembly stop 5-7; when the energy storage transmission component a is in a free state, the spring 6 acts on the connecting rod 5 and the energy storage shaft s respectively to make the two have a tendency to rotate relative to each other in opposite directions, so that the energy storage shaft s is limitedly engaged with the assembly stop 5-7, and the energy storage transmission component a is kept in an assembled state.

[0135] Furthermore, the connecting shaft 3 and the driving shaft 4 are fixedly connected by a coupling structure, and the coupling structure includes a connecting shaft coupling portion 3-2 provided on the connecting shaft 3 and a driving shaft coupling portion 4-2 provided on the driving shaft 4. The connecting shaft coupling portion 3-2 is provided with a connecting shaft anti-foolproofing structure 3-20, and the driving shaft coupling portion 4-2 is provided with a driving shaft anti-foolproofing structure 4-200. When the connecting shaft anti-foolproofing structure 3-20 and the driving shaft anti-foolproofing structure 4-200 cooperate, the connecting shaft 3 and the driving shaft 4 are connected together in a preset relative posture, ensuring that the connecting shaft 3 and the driving shaft 4 are correctly assembled together.

[0136] Specifically, the connecting shaft coupling portion 3-2 is a regular polygonal plug-in column having n side edges, and chamfered structures are provided at n-1 side edges (i.e., the connecting shaft chamfered structure 3-21); the drive shaft coupling portion 4-2 is provided with a drive shaft coupling hole 4-20 coaxial therewith, and the drive shaft coupling hole 4-20 has n inner angles, and chamfered structures are provided at n-1 inner top angles (i.e., the drive shaft chamfered structure 4-201); the plug-in column is plugged into the drive shaft coupling hole 4-20, and the side edges of the plug-in column without chamfered structures serve as the connecting shaft fool-proofing structure 3-20, and the inner top angles of the drive shaft coupling hole 4-20 without chamfered structures serve as the drive shaft fool-proofing structure 4-200; n is preferably ≥ 3.

[0137] It should be pointed out that the connecting shaft anti-foolproofing structure 3-20 and the driving shaft anti-foolproofing structure 4-200 are not limited to the above-mentioned implementation methods. For example, the connecting shaft anti-foolproofing structure 3-20 can be a convex rib provided on one side of the plug-in column, and the driving shaft anti-foolproofing structure 4-200 can be a groove provided on one side of the driving shaft coupling hole 4-20, and the convex rib and the groove cooperate with each other; or, the connecting shaft coupling portion 3-2 is a plug-in column with an irregular cross-section and a non-centrally symmetrical structure, and the driving shaft coupling hole 4-200 is an irregular hole that cooperates with the plug-in column; those skilled in the art can also make a variety of other modified designs, as long as it can ensure that the connecting shaft 3 and the driving shaft 4 are connected together in a preset relative posture, which will not be listed one by one here, and all should fall within the scope of protection of this application.

[0138] As shown in Figures 6-8 and 13, the energy storage shaft s is arranged to be movable relative to the connecting rod 5 along the axis o2-o2, that is, the energy storage shaft s can be moved relative to the connecting rod 5 in the direction of the axis o2-o2. Therefore, when the energy storage shaft s is installed in the connecting rod 5, one end of the energy storage shaft s can be inserted into one side wall of the connecting rod 5 first, and then the energy storage shaft s can be moved along the direction of the axis o2-o2 to insert the other end of the energy storage shaft s into the other side wall of the connecting rod 5, thereby completing the assembly of the energy storage shaft s and the connecting rod 5, which is conducive to simplifying the assembly operation of the energy storage shaft s and the connecting rod 5.

[0139] Specifically, the connecting shaft 3-0 of the connecting shaft 3 and the driving shaft 4-0 of the driving shaft 4 are respectively located at the axial ends of the energy storage shaft s. The free ends of the connecting shaft 3-0 of the connecting shaft 3 and the free ends of the driving shaft 4-0 of the driving shaft 4 are respectively rotatably inserted into the connecting rod front wall 5-1 and the connecting rod rear wall 5-3 of the connecting rod 5. During assembly, the connecting shaft 3-0 is first inserted into the connecting rod front wall 5-1, and then the energy storage shaft s is moved along the axis o2-o2 direction to insert the free end of the driving shaft 4-0 into the connecting rod rear wall 5-3. Furthermore, the free end of the connecting shaft 3-0 is rotatably inserted into the connecting rod front shaft hole 5-1s of the connecting rod front wall 5-1, and the free end of the driving shaft 4-0 is rotatably inserted into the connecting rod rear shaft hole 5-3s of the connecting rod rear wall 5-3.

[0140] The structure of the energy storage shaft s will be further described below in conjunction with Figures 8 and 12: In the driving shaft 4, the driven bevel gear 4-12 and the energy storage shaft matching part 4-11 are both arranged on the energy storage shaft driven part 4-1, and the driven bevel gear 4-12 is a fan-shaped gear. The gear teeth of the driven bevel gear 4-12 and the two energy storage shaft matching parts 4-11 are arranged at intervals along the circumference of the energy storage shaft driven part 4-1, and the two energy storage shaft matching parts 4-11 are located on both sides of the driven bevel gear 4-12 in the circumferential direction of the energy storage shaft driven part 4-1 (that is, the circumferential direction of the energy storage shaft s). After the connecting shaft 3 and the driving shaft 4 are assembled, the connecting shaft coupling portion 3-2 of the connecting shaft 3 is completely inserted into the driving shaft coupling hole 4-20 of the driving shaft coupling portion 4-2 of the driving shaft 4. In the direction of the axis o2-o2 (that is, in the axial direction of the energy storage shaft s), the connecting shaft trunk 3-0, the connecting portion 3-1, the driving shaft coupling portion 4-2, the driving shaft driven portion 4-1 and the driving shaft trunk 4-2 are arranged in sequence.

[0141] As shown in Figures 17-18, the operating mechanism o also includes at least one auxiliary switch. The auxiliary switch is activated or released when the connecting rod 5 rotates and switches positions. "Release" refers to the disconnection between the connecting rod 5 and the auxiliary switch, thereby deactivating the auxiliary switch. The auxiliary switch 8 generates signals based on the actions of the operating mechanism o, indicating the completion status and current state of the operating mechanism o. This facilitates remote monitoring of the operating mechanism and prevents user misoperation, thereby preventing situations such as electric shock.

[0142] Specifically, the auxiliary switch includes a switch trigger portion. When the connecting rod 5 rotates to switch positions, it presses or releases the switch trigger portion of the auxiliary switch. That is, when the connecting rod 5 presses the switch trigger portion, the auxiliary switch is triggered. When the connecting rod 5 releases the switch trigger portion, the auxiliary switch is deactivated. After the connecting rod 5 releases the switch trigger portion, the switch trigger portion can automatically reset to prepare for the next triggering of the auxiliary switch. Furthermore, the switch trigger portion is a trigger rod or a trigger button.

[0143] Furthermore, as shown in Figures 17-18, the operating mechanism o includes four auxiliary switches 8. Two auxiliary switches 8 engage with one end of the connecting rod 5 and are located on either side of the connecting rod 5 in the direction of axis o2-o2. The other two auxiliary switches 8 engage with the other end of the connecting rod 5 and are located on either side of the connecting rod 5 in the direction of axis o2-o2. Furthermore, the two auxiliary switches 8 engage with the same end of the connecting rod 5 and are symmetrically arranged on either side of the connecting rod 5. The four auxiliary switches 8 are triggered or released synchronously by the connecting rod 5.

[0144] Specifically, the two ends of the connecting rod 5 are respectively the first trigger end and the second trigger end. The two auxiliary switches 8 cooperating with the first trigger end are first switches, and the two first switches are symmetrically arranged on both sides of the connecting rod 5. The two auxiliary switches 8 cooperating with the second trigger end are second switches, and the two second switches are symmetrically arranged on both sides of the connecting rod 5; when the connecting rod 5 is in the third position, the first trigger end releases the first switch and the second trigger end releases the second switch; when the connecting rod 5 is in the fourth position, the first trigger end triggers the first switch and the second trigger end triggers the second switch.

[0145] As another embodiment, when the first trigger end triggers the first switch, the second trigger end releases the second switch; and when the first trigger end releases the first switch, the second trigger end triggers the second switch. Specifically, when the connecting rod 5 is in the third position, the first trigger end triggers the first switch, and the second trigger end releases the second switch; when the connecting rod 5 is in the fourth position, the first trigger end releases the first switch, and the second trigger end triggers the second switch.

[0146] As shown in Figure 17, the mechanism housing 1 is a square box-shaped structure comprising four dihedral angles circumferentially surrounding the energy storage axis s. A pair of dihedral angles is defined as a first dihedral angle and a second dihedral angle, respectively. Two first switches are positioned at the first dihedral angle, and two second switches are positioned at the second dihedral angle. Furthermore, the two first switches and the two second switches are centrally symmetrical with respect to each other, with the center of symmetry being axis o2-o2. Furthermore, the mechanism housing 1 is provided with switch mounting slots, each of which is configured to accommodate four sets of auxiliary switches 8.

[0147] As shown in FIG18 , the connecting rod 5 includes an indented notch 5-8, two of which are formed on either side of one end of the connecting rod 5 (i.e., two indented notches 5-8 are formed on either side of one end of the connecting rod front wall 5-1 and the connecting rod rear wall 5-3) and are arranged side by side along the axis o2-o2. Another two indented notches 5-8 are formed on either side of the other end of the connecting rod 5 (i.e., another two indented notches 5-8 are formed on either side of the other end of the connecting rod front wall 5-1 and the connecting rod rear wall 5-3) and are arranged side by side along the axis o2-o2. The four indented notches 5-8 correspond to the four auxiliary switches 8, respectively. When the connecting rod 5 triggers the auxiliary switches 8, each auxiliary switch 8 enters the corresponding indented notch 5-8. The indented notches 5-8 are conducive to improving the compactness of the layout of the auxiliary switches 8 and the connecting rod 5, thereby improving the compactness of the layout of the operating mechanism o and reducing the space required for the operating mechanism o. Furthermore, the two indentations at the same end of the connecting rod 5 are respectively located on both sides of the corresponding spring cavity 51 c , that is, on both sides of the corresponding spring 6 .

[0148] As shown in Figures 13 and 18, the connecting rod 5 also includes a trigger portion 5-5 for triggering the auxiliary switch 8. Furthermore, the connecting rod 5 is provided with four trigger portions 5-5, each for triggering the four auxiliary switches 8, two of which are located on both sides of one end of the connecting rod 5 (i.e., the two trigger portions 5-5 are located on both sides of one end of the connecting rod front wall 5-1 and the connecting rod rear wall 5-3), and the other two trigger portions 5-5 are located on both sides of the other end of the connecting rod 5 (i.e., the other two trigger portions 5-5 are located on both sides of the other end of the connecting rod front wall 5-1 and the connecting rod rear wall 5-3). Furthermore, two of the trigger portions 5-5 are disposed in two indentations 5-8 at one end of the connecting rod 5, and the other two trigger portions 5-5 are disposed in two indentations 5-8 at the other end of the connecting rod 5.

The first end section 5-12 of the side wall and the second end section 5-14 of the side wall are arranged relative to the side wall output section 5-10 toward the connecting rod front wall 5-1 and The connecting rod rear wall 5-13 is offset, the first end section 5-12 of the side wall and the first connecting section 5-11 of the side wall form a right-angled concave notch 5-8, and the second end section 5-14 of the side wall and the second connecting section 5-13 of the side wall form a right-angled concave notch 5-8; a spring cavity 51c is formed between the first end section 5-12 of the side wall of the connecting rod front wall 5-1 and the connecting rod rear wall 5-3, an axis cavity 50c is formed between the side wall output section 5-10 of the connecting rod front wall 5-1 and the connecting rod rear wall 5-3, a spring cavity 51c is formed between the second end section 5-14 of the side wall of the connecting rod front wall 5-1 and the connecting rod rear wall 5-3, and a connecting rod shaft 5o is provided on the outer surface of the side wall output section 5-10 of the connecting rod front wall 5-1 and the connecting rod rear wall 5-3. Furthermore, the first connecting section 5-11 of the side wall and the second connecting section 5-13 of the side wall are parallel to each other and parallel to the axis o2-o2. Furthermore, each of the trigger parts 5-5 is a trigger plate, which is arranged in the corresponding concave notch 5-8, and the two side edges of the trigger plate are connected to the two adjacent side walls of the concave notch 5-8, that is: a trigger plate arranged in the concave notch 5-8 surrounded by the first end section 5-12 of the side wall and the first connecting section 5-11 of the side wall, the two side edges of the trigger plate are respectively connected to the first end section 5-12 of the side wall and the first connecting section 5-11 of the side wall; a trigger plate arranged in the concave notch 5-8 surrounded by the second end section 5-14 of the side wall and the second connecting section 5-13 of the side wall, the two side edges of the trigger plate are respectively connected to the second end section 5-14 of the side wall and the second connecting section 5-13 of the side wall; the trigger part 5-5 and the corresponding side wall of the connecting rod 5 are an integral structure.

The output structure and the mechanism housing assembly structure are centrally symmetrical, allowing the operating mechanism to be adjusted according to the requirements of the installation environment and operational convenience.
