Description

Technical Field

[0001] The invention relates to the field of low-voltage electrical appliances, and in particular to an operating mechanism and a switch electrical appliance comprising the operating mechanism. Background Art

[0002] Switching electrical appliances are used to close and open circuits, and include an operating mechanism and at least one switch unit. The operating mechanism is transmission-connected to the moving contact mechanism of the switch unit, driving the moving contact mechanism to rotate and close and disconnect with 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.

[0003] The operating mechanism of the existing switch 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 energy 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 switch device.

[0004] In addition, the operating mechanism of the existing switch electrical appliance occupies a large space as a whole.

[0078] The following is a further description of the specific implementation of the switch device of the present invention in conjunction with the embodiments given in the accompanying drawings. The switch device of the present invention is not limited to the description of the following embodiments.

[0079] like Figure 1-19 As shown, it is an embodiment of the switch electrical appliance of the present invention. 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 shell 9 and a contact system arranged in the unit shell 9. The contact system includes a moving contact mechanism m and a static contact used in conjunction with each other. The moving contact mechanism m is rotatably arranged. The operating mechanism o is transmission-connected with the moving contact mechanism m of the switch unit p to drive the contact system 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 direction of the moving contact mechanism m. Further, the isolating switch includes multiple groups of switch units p, each of which is arranged side by side along the rotation axis direction of the moving contact mechanism m and is closed and opened synchronously under the drive of the operating mechanism o.

[0080] 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.

[0081] like Figure 1-19 The figure shows an embodiment of the operating mechanism o.

[0082] like Figure 1-3, as shown in Figures 5 - 8 and 16, the operating mechanism o of the first embodiment includes a mechanism housing 1, an operating shaft 2 disposed within the mechanism housing 1, and an energy storage transmission assembly a; the operating shaft 2 is driven by an external force to reciprocate and switch between a tripping position and a closing position; the energy storage transmission assembly a includes a connecting rod 5 that reciprocally rotates about an axis o2 - o2 and switches between a third position and a fourth position and is used to be drivingly connected to the moving contact mechanism m of the switching device, a energy storage shaft s that reciprocally rotates about the axis o2 - o2 and switches between a first position and a second position, and a spring 6 with two ends respectively rotatably connected to the connecting rod 5 and the energy storage shaft s. The connecting rod 5 and the energy storage shaft s are coaxially rotatably disposed, and the energy storage shaft s is driven to rotate by the operating shaft 2; 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 to drive the energy storage shaft s and the connecting rod 5 to rotate in two opposite directions respectively.

[0083] Specifically, the connecting rod 5 and the energy storage shaft s are coaxially rotatably disposed, and their rotation axes are both the axis o2 - o2; the connecting rod 5 has two working positions, which are the third position and the fourth position respectively. The connecting rod 5 is rotatably disposed about the axis o2 - o2 and switches between the third position and the fourth position by reciprocating rotation. The connecting rod 5 is also used to be drivingly connected to the moving contact mechanism m of the switching device to drive the moving contact mechanism m to rotate to close and disconnect from the corresponding static contact; the energy storage shaft s has two working positions, which are the first position and the second position respectively. The energy storage shaft s is rotatably disposed about the 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 and drive the energy storage shaft s to reciprocally rotate, so that the energy storage shaft s switches between its two working positions. When the operating mechanism o performs a tripping or closing operation, the operating shaft 2 is driven by an external force (the external force can come from manual operation by the user or from an 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 (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 working positions. During the rotation of the energy storage shaft s, first, the spring 6 is driven to move to the maximum energy storage position (as shown in part (2) of Figure 16 ), so that the spring 6 completes energy storage (as shown in parts (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 about the axis o2 - o2, and the end of the spring 6 connected to the connecting rod 5 remains stationary). Then, the energy storage shaft s drives the spring 6 to cross the maximum energy storage position, and then the spring 6 starts to release energy. The spring 6 releases energy to drive the energy storage shaft s to continue rotating in the original rotation direction and at the same time drives the connecting rod 5 to rotate in a direction opposite to that of the energy storage shaft s until the energy storage shaft s and the connecting rod 5 complete position switching (as shown inFigure 16 As shown in parts (2)-(3), 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 pass the maximum energy storage position through the energy storage shaft s, the connecting rod 5 remains stationary and will not rotate due to the movement 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: when the operating mechanism o is in the opening state, the operating shaft 2 is in the opening 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 closing state, the operating shaft 2 is in the closing position, the energy storage shaft s is in the second position and the connecting rod 5 is in the fourth position; that is to say, the operating shaft 2 is driven by an external force to rotate from the opening position to the closing position, so that the operating mechanism o performs the closing operation and switches from the opening state to the closing state; the operating shaft 2 is driven by an external force to rotate from the closing position to the opening position, so that the operating mechanism o performs the opening operation and switches from the closing state to the opening state.

[0084] Compared with the scheme of the existing operating mechanism 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 both ends of the spring 6 that can move, so that the operating mechanism of this embodiment can achieve a significant increase in the rotation angle of the connecting rod 5 under the condition of a space size similar to that of the existing operating mechanism, thereby greatly improving the final gap (that is, the breaking gap between the moving contact and the static contact) at which the moving contact mechanism connected to the connecting rod 5 is disconnected, thereby greatly improving the breaking performance and electrical performance of the switch electrical appliance using the operating mechanism o of this embodiment, especially for the breaking of large current DC circuits; and the operating mechanism o of this embodiment has a simple structure, a compact layout, and requires less space.

[0085] Further, such as Figure 3 , 6, as shown in FIGS. 13 and 15, when the spring 6 acts on the energy storage shaft s to establish a first limit fit with the mechanism housing 1 and hold 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 limit fit with the mechanism housing 1 and hold 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 in the first direction (or the second direction) in the first position (or the second position) and switches 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 hold 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 hold 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) and switches to the fourth position or the third position.

[0086] Specifically, when the energy storage shaft s switches from the first position to the second position, the energy storage shaft s rotates in the first direction, the energy storage shaft s drives the spring 6 to act to the maximum energy storage position and cross the maximum energy storage position, the spring 6 releases energy and drives the energy storage shaft s to continue rotating towards the second position until the energy storage shaft s establishes a second limit fit with the mechanism housing 1 and the energy storage shaft s is limited in the second position; when the energy storage shaft switches from the second position to the first position, the energy storage shaft s rotates in the second direction, the energy storage shaft s drives the spring 6 to act to the maximum energy storage position and cross the maximum energy storage position, the spring 6 releases energy and drives the energy storage shaft s to continue rotating towards the first position until the energy storage shaft s establishes a first limit fit with the mechanism housing 1 and the energy storage shaft s is limited in 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 the connecting rod 5 is limited in 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 the connecting rod 5 is limited in the third position.

[0087] As Figure 6 and 9As shown, the energy storage drive assembly a has at least one assembled state; when the energy storage drive assembly a is in the free state, that is, when the energy storage drive 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 two opposite directions, and enabling the connecting rod 5 and the energy storage shaft s to be limitedly matched to prevent the relative rotation of the connecting rod 5 and the energy storage shaft s, thereby maintaining the energy storage drive assembly a in the assembled state. The assembled state of the energy storage drive assembly a enables the energy storage shaft s, the connecting rod 5, and the spring 6 of the energy storage drive assembly a to be pre-assembled together. When applied to the operating mechanism o, it can be assembled into the operating mechanism o as a whole, which is beneficial to reducing the assembly difficulty of the operating mechanism o, simplifying the operation, and improving the assembly efficiency. Further, the energy storage drive assembly a has two assembled states. In the two assembled states, the spring 6 acts on the connecting rod 5 and the energy storage shaft s respectively, causing the two to have a tendency to rotate in opposite directions; in the two assembled states of the energy storage drive assembly a, the energy storage shaft s has a tendency to rotate in two opposite directions under the action of the spring 6, and the connecting rod 5 has a tendency to rotate in two opposite directions under the action of the spring 6. That is: the two assembled states are the first assembled state and the second assembled state respectively; in the first assembled state of the energy storage drive assembly a, the spring 6 acts on the energy storage shaft s to make it have a tendency to rotate in the first direction and acts on the connecting rod 5 to make it have a tendency to rotate in the second direction; in the second assembled state of the energy storage drive assembly a, the spring 6 acts on the energy storage shaft s to make it have a tendency to rotate in the second direction and acts on the connecting rod 5 to make it have a tendency to rotate in the first direction. Further, when the operating mechanism o is in the closing state and the opening state, the energy storage drive assembly a is respectively in two assembled states. That is: when the operating mechanism o is in the closing state, the energy storage drive assembly a is in one assembled state, and the energy storage shaft s and the connecting rod 5 are limitedly matched (the two are limitedly matched in a relative posture); when the operating mechanism o is in the opening state, the energy storage drive assembly a is in another assembled state, and the energy storage shaft s and the connecting rod 5 are limitedly matched (the two are limitedly matched in another relative posture). When the operating mechanism o is in the closing state and the opening state, the limited matching of the energy storage shaft s and the connecting rod 5 prevents the relative rotation of the two, 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 noted that when the operating mechanism o is in the closing state and the opening state, the energy storage shaft s and the connecting rod 5 may also not have a limited matching. 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 matching.

[0088] As Figure 1-3As shown in , 5, the operating shaft 2 rotates around the axis o1-o1 and switches between the opening position and the closing position, that is, the operating shaft 2 has two working positions, which are the opening position and the closing position, respectively. The operating shaft 2 is arranged to rotate around the axis o1-o1 and switches between the opening position and the closing position by reciprocating rotation. The axis o1-o1 and the 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. Further, the axis o1-o1 and the axis o2-o2 are coplanar, and the two intersect vertically.

[0089] As another embodiment, the operating shaft 2 is arranged to move linearly, and the moving direction of the operating shaft 2 is perpendicular to the axis o2-o2; the operating shaft 2 is driven by an external force to move linearly back and forth, thereby driving the energy storage shaft s to reciprocate. Further, the operating shaft 2 and the energy storage shaft s are driven by a rack and a gear; or, the operating shaft 2 is provided with a toggle part, and the energy storage shaft s is provided with two sets of corresponding driven parts, and the reciprocating movement of the operating shaft 2 causes the toggle part to press against the two driven parts respectively, thereby causing the energy storage shaft s to reciprocate.

[0090] like Figure 2-3 As shown in Figures 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 an 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.

[0091] Specifically, the operating shaft driving part 2-1 includes a driving bevel gear rotatably arranged 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 rotatably arranged 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 meshed with the driven bevel gear 4-12.

[0092] As other embodiments, 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 that are relatively spaced apart, and the toggle block is located between the two driven blocks. The operating shaft 2 is rotated by an external force to drive the toggle block to swing, and the toggle block presses against the two driven blocks respectively to rotate the energy storage shaft s.

[0093] As another embodiment, the operating shaft 2 and the energy storage shaft s are matched through a worm gear transmission, and accordingly, the axis o1-o1 and the axis o2-o2 are not coplanar, and the two are perpendicular to each other only in space.

[0094] like Figure 1-3As shown in FIGS. 5 and 10, the operating shaft 2 further includes an operating shaft stem 2-0. The mechanism housing 1 includes a housing operating shaft hole 1-00. The operating shaft stem 2-0 is rotatably inserted into the housing operating shaft hole 1-00 and is driven by an external force to rotate the operating shaft 2, 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 portion 2-1.

[0095] Further, the other end of the operating shaft stem 2-0, that is, the end of the operating shaft stem 2-0 far from the operating shaft driving portion 2-1, protrudes outside the mechanism housing 1 for operation. Of course, the end of the operating shaft stem 2-0 far 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.

[0096] Further, a free end of the operating shaft stem 2-0, that is, the end of the operating shaft stem 2-0 far from the operating shaft driving portion 2-1, is provided with an operating shaft insertion hole 2-00. The operating mechanism o further includes an operating handle which is inserted into the operating shaft hole 2-00 for driving the operating shaft 2 to rotate. The operating shaft stem 2-0 is preferably further provided with a locking hole 2-01 which extends radially along the operating shaft stem 2-0 and intersects with the operating shaft insertion hole 2-00. A locking screw is arranged in the locking hole 2-01 and is threadedly connected thereto to fix the operating handle and the operating shaft stem 2-0 together.

[0097] Further, a mechanism housing clamping groove is provided on the inner side wall of the housing operating shaft hole 1-00. The mechanism housing clamping groove extends along the circumferential direction of the housing operating shaft hole 1-00. The operating shaft stem 2-0 includes a shaft positioning portion 2-02. 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. The shaft positioning portion 2-02 is inserted into the mechanism housing clamping groove to limit the movement of the operating shaft 2 along the axis o1-o1 direction, ensuring the reliable cooperation and transmission between the operating shaft 2 and the energy storage shaft s.

[0098] As Figure 1-2 As shown in FIGS. 6, 13, 17-19, the connecting rod 5 is provided with an output structure which passes through the side wall of the mechanism housing 1 and is used for driving connection with the moving contact mechanism m of the switching electrical appliance. Further, the output structure is served by the connecting rod shaft 5o of the connecting rod 5, which will be described in detail below.

[0099] As Figure 1-3 As shown in FIGS. 5-7, 13-15, the energy storage shaft s and the spring 6 are both arranged in the connecting rod 5. Further, the axial two ends of the energy storage shaft s are respectively rotatably arranged on the connecting rod 5. The above layout and assembly relationship design of the energy storage shaft s, the connecting rod 5 and the spring 6 is beneficial to further improving the structural compactness of the operating mechanism o in this embodiment and reducing the required space.

[0100] It should be noted that the energy storage shaft s and the spring 6 do not necessarily have to be arranged inside the connecting rod 5, and the axial two ends of the energy storage shaft s do not necessarily have to be rotatably arranged on the connecting rod 5. It only needs 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 cooperates with the energy storage shaft s and the connecting rod 5 respectively. For example, the axial two 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 arranged 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 is rotatably sleeved on the energy storage shaft. The above only lists some possible layout ways of the energy storage shaft s, the connecting rod 5 and the spring 6. Those skilled in the art can completely make other deformation designs on the basis of ensuring the action modes and cooperation relationships of the energy storage shaft s, the connecting rod 5 and the spring 6, and all should fall within the protection scope of this application.

[0101] As shown in Figure 1-2 Figures 13-15, the connecting rod 5 is rotatably arranged on the mechanism housing 1. Further, the connecting rod 5 can be directly rotatably arranged on the mechanism housing 1. For example, the connecting rod 5 is respectively rotatably arranged on a pair of side walls of the mechanism housing 1 through 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 arranged on the mechanism housing 1. For example, the connecting rod 5 is rotatably arranged on a bracket for supporting the connecting rod 5, and the bracket is fixedly arranged on the mechanism housing 1; or, the connecting rod 5 is indirectly rotatably arranged on the mechanism housing 1 through the energy storage shaft s.

[0103] Among the axial two ends of the energy storage shaft s, at least one end passes through the mechanism housing 1 for being operated by an external force to drive the energy storage shaft s to rotate.

[0104] Specifically, as shown in Figure 1-2As shown in FIGS. 6, 13, and 15, both axial ends of the energy storage shaft s pass through a pair of side walls of the mechanism housing 1 respectively for being driven to rotate by an external force; that is to say, both axial ends of the energy storage shaft s pass through a pair of side walls of the mechanism housing 1 respectively, and the external force can operate both ends of the energy storage shaft s respectively to drive it to rotate. The above design of the energy storage shaft s enables the operating mechanism o of the first embodiment to perform opening and closing operations not only through the operating shaft 2 but also through the energy storage shaft s, allowing users 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 an actual use scenario, although both axial ends of the energy storage shaft s can pass through the side walls of the mechanism housing 1 for 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 blocked by the switch unit p. According to actual needs, only one axial end of the energy storage shaft s passes through one side wall of the mechanism housing 1 for being driven to rotate by an external force. 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 for operating the operating mechanism o can be provided without omitting the operating shaft 2.

[0105] Further, as shown in Figure 3 , 5 , FIGS. 6 - 8, and 14, the energy storage transmission assembly a includes two sets of springs 6, and the two sets of springs 6 are respectively arranged on the radial two sides of the energy storage shaft s, and both ends of each set of springs 6 are respectively rotationally connected to the connecting rod 5 and the energy storage shaft s.

[0106] Specifically, the spring 6 is a linear compression spring, which includes a spring main body 60 and a first connecting portion and a second connecting portion respectively connected to both ends of the spring main 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 at the maximum energy storage position, the geometric axis of the spring 6 and the axis o2 - o2 are coplanar and perpendicular to each other.

[0107] As another embodiment, the spring 6 can also be a torsion spring, and both ends of it are respectively rotationally connected to the energy storage shaft s and the connecting rod 5; when the spring 6 is at the maximum energy storage position, the connecting line of the acting points of the spring 6 with the energy storage shaft s and the connecting rod 5 respectively is coplanar with the axis o2 - o2 and perpendicular to each other.

[0108] As shown in Figure 1-2 , the mechanism housing 1 includes a front half housing 1 - 1 and a rear half housing 1 - 2 that are relatively matched. Further, the front half housing 1 - 1 and the rear half housing 1 - 1 are relatively joined together along the axis o2 - o2 direction.

[0109] The following will give a detailed description of 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.

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

[0111] Specifically, the connecting rod cavity 5c includes a shaft cavity 50c and a spring cavity 51c. The two spring cavities 51c are symmetrically arranged on both sides of the shaft cavity 50c and communicate with it. The energy storage shaft s is rotatably arranged in the shaft cavity 50c, and the two springs 6 are respectively arranged in the two spring cavities 51c. Further, in the direction of the axis o2-o2, the width of the shaft cavity 50c > the width of the spring cavity 51c, and both ends of the shaft cavity 50c protrude on both sides of the spring cavity 51c.

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

[0113] As another embodiment, the connecting rod 5 can also be a split structure. The first end wall 5-2 is 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 is detachably connected to the connecting rod front wall 5-1 and the connecting rod rear wall 5-3, which is beneficial to reducing the production difficulty of the connecting rod 5, but 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 can be two metal shafts, and both ends of each metal shaft are respectively connected to the connecting rod front wall 5-1 and the connecting rod rear wall 5-3, and the second connecting part of the spring 6 is rotatably sleeved on the corresponding metal shaft.

[0114] Further, the axial ends of the energy storage shaft s are respectively rotatably arranged on a pair of side walls of the connecting rod 5. Further, the side walls of the connecting rod 5 are provided with connecting rod shaft holes, the axis of the connecting rod shaft holes coincides with the axis o2-o2, and the axial ends of the energy storage shaft s are respectively rotatably arranged in 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, and the axial ends of the energy storage shaft s are respectively rotatably arranged in the connecting rod front shaft hole 5-1s and the connecting rod rear shaft hole 5-3s. Further, the connecting rod shaft hole is a through hole.

[0115] Further, the connecting rod 5 also includes a connecting rod shaft 5o, the axis of the connecting rod shaft 5o coincides with the axis o2-o2, and the two connecting rod shafts 5o are respectively arranged on the axial sides of the connecting rod 5; the mechanism housing 1 also includes two housing shaft holes 1o respectively arranged on a pair of side walls thereof, and the two connecting rod shafts 5o are respectively rotatably inserted in the two housing output shaft holes 1o. Further, the two housing output shaft holes 1o are through holes, and the two connecting rod shafts 5o can be connected to the moving contact mechanism m of the switch 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 switch electrical appliance can be arranged on both sides of the operating mechanism o, and the two connecting rod shafts 5 are respectively 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 set the switch unit p on only one side of the operating mechanism o in the direction of the axis o2-o2, and 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, so as to provide external force operation to drive the operating shaft s to rotate.

[0117] As other embodiments, the connecting rod shaft 50 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 50 of the connecting rod 5 is only used as an output structure to realize the transmission connection between the connecting rod 5 and the moving contact mechanism m, and the connecting rod 5 is provided with other structures to realize the rotation setting of the connecting rod 5.

[0119] Further, the connecting rod 5 further includes a connecting rod spring seat 5-6 provided on the end wall. The connecting rod spring seat 5-6 is provided with a connecting rod spring groove; 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 arranged in the connecting rod spring groove 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 the connecting rod spring seat 5-6.

[0120] As Figure 3-8 shown in FIGS. 11 and 14, the energy storage shaft s further includes a connecting arm 3-10. One end of the spring 6 is rotatably connected to the connecting arm 3-0 and the other end is rotatably connected to the connecting rod 5.

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

[0125] like Figure 3 , 15As shown, the mechanism housing 1 includes two energy storage shaft stop surfaces 1-00b and two connecting rod stop surfaces 1-10b. The two energy storage shaft stop surfaces 1-00b are respectively the first stop surface and the second stop surface. The energy storage shaft s is in limit fit with the first stop surface to prevent the energy storage shaft s from rotating in the second direction and limit the energy storage shaft s at the first position. The energy storage shaft s is in limit fit with the second stop surface to prevent the energy storage shaft s from rotating in the first direction and limit the energy storage shaft s at the second position. The two connecting rod stop surfaces 1-10b are respectively the third stop surface and the fourth stop surface. The connecting rod 5 is in limit fit with the third stop surface to prevent the connecting rod 5 from rotating in the second direction and limit the connecting rod 5 at the third position. The connecting rod 5 is in limit fit with the fourth stop surface to prevent the connecting rod 5 from rotating in the first direction and limit the connecting rod 5 at the fourth position.

[0126] Specifically, the two energy storage shaft stop surfaces 1-00b are arranged in a V shape; the two connecting rod stop surfaces 1-10b are arranged in a V shape. The two connecting rod stop surfaces 1-10b are respectively located on the radial two sides of the operating shaft 2; the openings of the V-shaped structures formed by the two energy storage shafts s are opposite to the openings of the V-shaped structures formed by the two connecting rod stop surfaces 1-10b; in the radial direction of the energy storage shaft s, the two energy storage shaft stop surfaces 1-00b are located on one side of the energy storage shaft s and on one side of the energy storage transmission assembly a, and the two connecting rod stop surfaces 1-10b are located on the other side of the energy storage shaft s and on the other side of the energy storage transmission assembly a. Further, the housing 1 includes a housing stop energy storage shaft part 1-0b and a housing stop connecting rod part 1-1b. The housing stop energy storage shaft part 1-0b and the housing stop connecting rod part 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 stop surfaces 1-00b are both provided on the housing stop energy storage shaft 1-0b, and the two connecting rod stop surfaces 1-10b are both provided on the housing stop connecting rod part 1-1b. Further, the housing stop energy storage shaft part 1-0b is provided on the rear half housing 1-2; the housing stop connecting rod part 1-1b includes sub-stop parts respectively provided on the front half housing 1-1 and the rear half housing 1-2. The two sub-stop parts are relatively spliced together along the axis o2-o2 direction and are respectively matched with a pair of side walls of the connecting rod 5.

[0127] Further, as Figure 2-9 shown in Figures 11 and 12, the energy storage shaft s includes an energy storage shaft mating part 4-11, and the energy storage shaft mating part 4-11 is in limit fit with the first stop surface and the second stop surface respectively.

[0128] Specifically, the energy storage shaft s includes two energy storage shaft mating portions 4-11. The two energy storage shaft mating portions 4-11 are arranged at intervals along the axial direction of the energy storage shaft s and are respectively a first energy storage shaft mating portion and a second energy storage shaft mating portion. The first energy storage shaft mating portion is used for limiting and mating with the first stop surface, and the second energy storage shaft mating portion is used for limiting and mating with the second stop surface. Further, each of the energy storage shaft mating portions 4-11 is provided with a first mating surface for respectively limiting and mating with the two first stop surfaces. Both ends of the connecting rod 5 are respectively limited and mated with the two connecting rod stop surfaces 1-10b, and the connecting rod 5 is respectively limited at the third position and the fourth position. Further, both ends of the side edge of the side wall of the connecting rod 5 are respectively limited and mated with the two connecting rod stop surfaces 1-10b.

[0129] As Figure 2-3 shown in FIGS. 6 and 9, the connecting rod 5 further includes an assembly blocking portion 5-7; in the free state of the energy storage transmission assembly a, the spring 6 acts on the connecting rod 5 and the energy storage shaft s respectively, causing the two to have a tendency of relative rotation in opposite directions, so that the energy storage shaft s is limited and mated with the assembly blocking portion 5-7, and the energy storage transmission assembly a is maintained in the assembled state.

[0130] Specifically, in the first assembled state of the energy storage transmission assembly a, one energy storage shaft mating portion 4-11 of the energy storage shaft s is limited and mated with the assembly blocking portion 5-7; in the second assembled state of the energy storage transmission assembly a, the other energy storage shaft mating portion 4-11 of the energy storage shaft s is limited and mated with the assembly blocking portion 5-7; in the two assembled states of the energy storage transmission assembly a, the energy storage shaft s has a tendency to rotate in two opposite directions under the action of the spring 6, and the connecting rod 5 has a tendency to rotate in two opposite directions under the action of the spring 6.

The two assembly stop surfaces are used for respectively limiting and mating with the two second mating surfaces 4-111, and the energy storage transmission assembly a is respectively maintained in the two assembled states. Further, in the energy storage mating portion 4-11, the first mating surface 4-110 and the second mating surface 4-111 are opposite and are respectively arranged on both sides of the energy storage mating portion 4-11. Further, the two assembly stop surfaces are respectively arranged at both ends of the assembly blocking portion 5-7.

[0131] Further, the assembly stop portion 5-7 is provided on the rear wall 5-3 of the connecting rod and extends between the rear wall 5-3 and the front wall 5-1 of the connecting rod. Further, the assembly stop portion 5-7 is provided on the side edge of the rear wall 5-3 of the connecting rod and is bent and connected to the rear wall 5-3 of the connecting rod.

[0132] As Figure 6-8 As shown in FIGS. 11-12, the energy storage shaft s includes a connecting shaft 3 and a driving shaft 4 that are coaxially and fixedly connected. The spring 6 cooperates with the connecting shaft 3 and the connecting rod 5 respectively, and the operating shaft 2 is in transmission cooperation with the driving shaft 4; the energy storage shaft s is composed of a connecting shaft 3 and a driving shaft 4 that are separately designed and fixedly connected, which is beneficial to reducing the production difficulty of the energy storage shaft s.

[0133] Specifically, the connecting portion 3-1 includes two connecting arms 3-10, and the two ends of the connecting portion 3-1 in the radial direction of the energy storage shaft s are respectively two connecting arms 3-10.

[0134] Further, the connecting shaft 3 further includes a connecting shaft stem 3-0 and a connecting shaft joint portion 3-2, and the connecting shaft stem 3-0, the connecting portion 3-1 and the connecting shaft joint portion 3-2 are coaxially connected in sequence; the driving shaft 4 further includes a driving shaft stem 4-0 and a driving shaft joint portion 4-2, and the driving shaft stem 4-0, the energy storage shaft driven portion 4-1 and the driving shaft joint portion 4-2 are coaxially connected in sequence; the connecting shaft joint portion 3-2 and the driving shaft joint portion 4-2 cooperate to realize the fixed connection of the connecting shaft 3 and the energy storage shaft 4.

[0135] Further, the connecting shaft 3 and the driving shaft 4 are fixedly connected through a coupling structure. The coupling structure includes a connecting shaft joint portion 3-2 provided on the connecting shaft 3 and a driving shaft joint portion 4-2 provided on the driving shaft 4. The connecting shaft joint portion 3-2 is provided with a connecting shaft anti-fooling structure 3-20, and the driving shaft joint portion 4-2 is provided with a driving shaft anti-fooling structure 4-200. After the connecting shaft anti-fooling structure 3-20 and the driving shaft anti-fooling 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 joint portion 3-2 is a plug post with a regular polygon shape. The plug post has n side edges, and chamfer structures (i.e., the connecting shaft chamfer structure 3-21) are provided at n-1 side edges; the driving shaft joint portion 4-2 is provided with a driving shaft joint hole 4-20 coaxial with it.

[0138] As Figure 6-8 shown in FIGS. 13, the energy storage shaft s is movably arranged relative to the connecting rod 5 along the axis o2-o2, that is, the energy storage shaft s can move relative to the connecting rod 5 in the direction of the axis o2-o2. Thus, when installing the energy storage shaft s into the connecting rod 5, one end of the energy storage shaft s can be first inserted into one side wall of the connecting rod 5, and then the energy storage shaft s is moved along the axis o2-o2 so that the other end of the energy storage shaft s is inserted 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 beneficial to simplifying the assembly operation of the energy storage shaft s and the connecting rod 5.

[0139] Specifically, the connecting shaft stem 3-0 of the connecting shaft 3 and the driving shaft stem 4-0 of the driving shaft 4 are respectively located at the two axial ends of the energy storage shaft s. The free ends of the connecting shaft stem 3-0 of the connecting shaft 3 and the driving shaft stem 4-0 of the driving shaft 4 are respectively rotatably inserted into the front connecting rod wall 5-1 and the rear connecting rod wall 5-3 of the connecting rod 5. During assembly, the connecting shaft stem 3-0 is first inserted into the front connecting rod 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 stem 4-0 into the rear connecting rod wall 5-3. Further, the free end of the connecting shaft stem 3-0 is rotatably inserted into the front connecting rod shaft hole 5-1s of the front connecting rod wall 5-1, and the free end of the driving shaft stem 4-0 is rotatably inserted into the rear connecting rod shaft hole 5-3s of the rear connecting rod wall 5-3.

[0140] The following will combine Figure 8 and 12 to further illustrate the structure of the energy storage shaft s: In the driving shaft 4, the driven bevel gear 4-12 and the energy storage shaft mating part 4-11 are both arranged on the energy storage shaft driven part 4-1. The driven bevel gear 4-12 is a sector gear. The teeth of the driven bevel gear 4-12 and the two energy storage shaft mating parts 4-11 are arranged at intervals along the circumferential direction of the energy storage shaft driven part 4-1. The two energy storage shaft mating 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 joint part 3-2 of the connecting shaft 3 is completely inserted into the driving shaft joint hole 4-20 of the driving shaft joint part 4-2 of the driving shaft 4. In the direction of the axis o2-o2 (that is, the axial direction of the energy storage shaft s), the connecting shaft stem 3-0, the connecting part 3-1, the driving shaft joint part 4-2, the driving shaft driven part 4-1, and the driving shaft stem 4-2 are arranged in sequence.

[0141] As Figure 17-18 shown, the operating mechanism o further includes at least one auxiliary switch. When the connecting rod 5 switches positions by rotating, the auxiliary switch is triggered or released. The "release" means that the connecting rod 5 is disengaged from the auxiliary switch, so that the auxiliary switch is released from the triggered state. The auxiliary switch 8 can give corresponding signals according to the actions of the operating mechanism o, so as to indicate the completion status of the operation of the operating mechanism o and the current state of the operating mechanism o, which is beneficial to realizing the remote monitoring of the operating mechanism and can prevent users from misoperating, thus avoiding situations such as electric shock.

[0142] Specifically, the auxiliary switch includes a switch trigger part. When the connecting rod 5 switches positions by rotation, it presses against or releases the switch trigger part of the auxiliary switch. That is, when the connecting rod 5 presses against the switch trigger part, the auxiliary switch is triggered. After the connecting rod 5 releases the switch trigger part, the auxiliary switch is de-triggered. After the connecting rod 5 releases the switch trigger part, the switch trigger part can reset itself to prepare for the next trigger of the auxiliary switch. Further, the switch trigger part is a trigger rod or a trigger button.

[0143] Further, as Figure 17-18 shown, the operating mechanism o includes four auxiliary switches 8. Two auxiliary switches 8 cooperate with one end of the connecting rod 5 and are located on both sides of the connecting rod 5 in the direction of the axis o2-o2. The other two auxiliary switches 8 cooperate with the other end of the connecting rod 5 and are located on both sides of the connecting rod 5 in the direction of the axis o2-o2. Further, the two auxiliary switches 8 that cooperate with the same end of the connecting rod 5 are symmetrically arranged on both sides of the connecting rod 5, and 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 a first trigger end and a second trigger end respectively. The two auxiliary switches 8 that cooperate 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 that cooperate 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. 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 Figure 17 shown, the mechanism housing 1 is a square box-shaped structure, which includes four dihedral angles that surround the energy storage shaft s in the circumferential direction of the energy storage shaft s. One pair of dihedral angles are the first dihedral angle and the second dihedral angle respectively. The two first switches are arranged at the first dihedral angle, and the two second switches are arranged at the second dihedral angle. Further, the two first switches and the two second switches are centrosymmetric structures with each other, and the center of symmetry is the axis o2-o2. Further, the mechanism housing 1 is provided with switch mounting grooves, and the four switch mounting grooves are respectively used to accommodate four groups of auxiliary switches 8.

[0147] As Figure 18As shown, the connecting rod 5 includes concave notches 5-8. Two concave notches 5-8 are formed on both sides of one end of the connecting rod 5 (that is, two concave notches 5-8 are formed on both sides of one end of the front wall 5-1 and the rear wall 5-3 of the connecting rod) and are arranged side by side along the axis o2-o2. Another two concave notches 5-8 are formed on both sides of the other end of the connecting rod 5 (that is, another two concave notches 5-8 are formed on both sides of the other end of the front wall 5-1 and the rear wall 5-3 of the connecting rod) and are arranged side by side along the axis o2-o2. The four concave notches 5-8 respectively cooperate with the four auxiliary switches 8 correspondingly. When the connecting rod 5 triggers the auxiliary switches 8, each auxiliary switch 8 enters the corresponding concave notch 5-8. The concave notches 5-8 are beneficial 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 by the operating mechanism o. Further, the two concave notches at the same end of the connecting rod 5 are respectively located on both sides of the corresponding spring cavity 51c, that is, on both sides of the corresponding spring 6.

[0148] As Figure 13 and 18 shown, the connecting rod 5 further includes a triggering portion 5-5 for triggering the auxiliary switch 8. Further, the connecting rod 5 is provided with four triggering portions 5-5, which are respectively used to trigger the four auxiliary switches 8. Two triggering portions 5-5 are located on both sides of one end of the connecting rod 5 (that is, two triggering portions 5-5 are located on both sides of one end of the front wall 5-1 and the rear wall 5-3 of the connecting rod), and the other two triggering portions 5-5 are located on both sides of the other end of the connecting rod 5 (that is, the other two triggering portions 5-5 are located on both sides of the other end of the front wall 5-1 and the rear wall 5-3 of the connecting rod). Further, the two triggering portions 5-5 are arranged in the two concave notches 5-8 at one end of the connecting rod 5, and the other two triggering portions 5-5 are arranged in the two concave notches 5-8 at the other end of the connecting rod 5.

Further, the first sidewall connection segment 5-11 and the second sidewall connection segment 5-13 are parallel to each other and parallel to the axis o2-o2. Further, each trigger portion 5-5 is a trigger plate disposed in the corresponding concave notch 5-8, and the two side edges of the trigger plate are connected to the adjacent two sidewalls of the concave notch 5-8. That is, the trigger plate disposed in the concave notch 5-8 formed by the first sidewall end segment 5-12 and the first sidewall connection segment 5-11, and the two side edges of this trigger plate are respectively connected to the first sidewall end segment 5-12 and the first sidewall connection segment 5-11; the trigger plate disposed in the concave notch 5-8 formed by the second sidewall end segment 5-14 and the second sidewall connection segment 5-13, and the two side edges of this trigger plate are respectively connected to the second sidewall end segment 5-14 and the second sidewall connection segment 5-13; the trigger portion 5-5 and the corresponding sidewall of the link 5 are of an integral structure.
