Abstract
Description
Technical Field
[0001] The present disclosure relates to the electrical field, and in particular to an operating mechanism and an electrical device including the operating mechanism. Background Art
[0002] In some electrical devices with closing and opening functions, for example, in a ring main unit, the energy required for closing and / or opening operations may be large, so some energy storage devices are needed to assist the opening and / or closing operations. The energy storage device can be in the form of an opening spring and a closing spring, for example, the opening spring and / or the closing spring stores elastic potential energy through work such as charging operations, and releases the elastic potential energy when an opening or closing operation is required to complete the corresponding operation.
[0003] However, the existing operating mechanism for realizing energy charging has the problem of unstable operation. For example, after storing energy in the energy storage device, the operating structure cannot be released as expected, for example, it is frozen and stuck by grease at low temperature, which makes the operating mechanism block the energy release of the energy storage device, for example, block the opening of the electrical device, which will cause extremely serious safety hazards.
[0004] Therefore, a kind of operating mechanism with excellent performance and stability is needed to solve these problems. Utility Model Content
[0005] The purpose of the present disclosure is to at least solve the shortcomings existing in the prior art. The present disclosure proposes an operating mechanism, including a housing; a base plate, configured to pivot between a first position and a second position relative to the housing; an actuator, configured to pivot relative to the housing in a first direction and a second direction opposite to the first direction; a hook arm member, which can be pivotally and movably mounted to the base plate relative to the base plate, has a first arm and a second arm, the first arm cooperates with the actuator and has opposite first and second sides; a locking member, which is mounted to the base plate and can abut against or separate from the second arm in equal proportion to the pivotal movement of the base plate. When the base plate is in the first position, when the actuator abuts against the first arm at the first side of the first arm, the locking member abuts against the second arm so that the hook arm member is stationary relative to the base plate, and the pivotal movement of the actuator in the first direction drives the hook arm member, the locking member and the base plate to move together, so that the base plate moves from the first position to the second position. When the base plate moves to the second position, the locking member is separated from the second arm, and the actuating member abuts against the first arm at the first side of the first arm to cause the hook arm member to pivot relative to the base plate until the first arm is separated from the actuating member.
[0006] For example, according to some embodiments of the present disclosure, the operating mechanism also includes a limiting elastic member, one end of which is fixed to the shell. During the movement of the substrate to the second position, the substrate drives the locking member to press against the other end of the limiting elastic member and causes the limiting elastic member to undergo elastic deformation. After the substrate moves to the second position, the limiting elastic member releases its elastic potential energy, causing the locking member to pivot relative to the substrate and separate from the second arm.
[0007] For example, according to some embodiments of the present disclosure, the limiting elastic member is configured to bias the hook arm member so that the second arm abuts against the locking member when the substrate is in the first position; the limiting elastic member is also configured to separate from the hook arm member when the substrate moves to the second position and leaves the first position.
[0008] For example, according to some embodiments of the present disclosure, the actuator has a finger portion extending away from a pivot axis of the actuator, and the actuator abuts against the first side or the second side of the first arm through the finger portion.
[0009] When the substrate is in the first position, when the finger of the actuator abuts against the first arm at the second side of the first arm and moves toward the first side of the first arm, the hook arm member is driven to overcome the movement of the limiting elastic member relative to the substrate and avoid the actuator, so that the finger of the actuator can move in the second direction to the first side of the first arm.
[0010] For example, according to some embodiments of the present disclosure, the hook arm member is provided with a sliding groove, the base plate is provided with a pivot portion extending into the sliding groove, the pivot portion is movable in the sliding groove, and the sliding groove has a pivot fitting edge.
[0011] When the pivot portion moves to abut against the pivoting engagement edge, the hook arm member can pivot relative to the base plate around the pivot portion through the pivoting engagement edge, so that the finger portion of the actuator can abut against the first arm on the first side or the second side. The position-limiting elastic member is further configured to bias the hook arm member so that the pivot portion abuts against the pivoting engagement edge when the base plate is in the first position.
[0012] For example, according to some embodiments of the present disclosure, a biasing member is further included, which biases the locking member so that the second arm can abut against the locking member when the pivot portion abuts against the pivot engagement edge.
[0013] For example, according to some embodiments of the present disclosure, the locking member has adjacent arc segments and avoidance segments, and when the arc segments abut against the second arm, the arc segments block the movement of the second arm toward the pivot axis of the locking member. When the base plate is located at the second position, the limiting elastic member releases elastic potential energy to cause the locking member to pivot relative to the base plate, so that the second arm breaks away from contact with the arc segment and faces the avoidance segment to separate from the second arm.
[0014] For example, according to some embodiments of the present disclosure, when the hook arm member pivots around the pivot portion relative to the base plate, the finger portion of the actuator is located between the first arm and the second arm to limit the pivoting range of the hook arm member.
[0015] For example, according to some embodiments of the present disclosure, the sliding slot further includes a limiting edge, and when the pivot portion is located at the limiting edge, the first arm does not contact the actuating member. The hook arm member is further configured such that when the first arm and the second arm are separated from the actuating member and the locking member respectively, the hook arm member moves relative to the base plate under the action of gravity until the limiting edge abuts against the pivot portion and the hook arm member comes to rest.
[0016] For example, according to some embodiments of the present disclosure, when the substrate moves from the second position to the first position under the action of an external force, the hook arm member and the limiting elastic member change from separation to abutment so that the hook arm member is blocked by the limiting elastic member and moves relative to the substrate until the second arm abuts against the locking member and the pivot portion moves from the limiting edge to the pivot mating edge so that the hook arm member and the substrate are relatively stationary.
[0017] For example, according to some embodiments of the present disclosure, the base plate pivots coaxially with the actuator.
[0018] The present disclosure also proposes an electrical device, which includes an energy storage device and an operating mechanism according to any one of the embodiments of the present disclosure, wherein movement of the substrate from a first position to a second position causes the energy storage device of the electrical device to store energy, and when the energy storage device releases energy, the substrate moves from the second position to the first position.
[0019] For example, according to some embodiments of the present disclosure, the energy storage device includes a closing spring and an opening spring, and the electrical device is configured to perform a closing operation by using the energy stored in the closing spring and to perform an opening operation by using the energy stored in the opening spring. When the opening spring releases energy to perform an opening operation, the substrate moves from the second position to the first position.
[0020] For example, according to some embodiments of the present disclosure, the actuator is driven by a motor, and the motor is configured to: after the opening operation is performed, drive the finger of the actuator to move from the second side of the first arm along the second direction to the first side of the first arm; when the substrate is located in the first position and the finger of the actuator is located on the first side of the first arm, drive the actuator to move along the first direction to cause the substrate to move from the first position to the second position.
[0021] For example, according to some embodiments of the present disclosure, the electrical device is a ring main unit. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In order to make the purpose, scheme and advantages of the technical solution of the present disclosure clearer, the technical solution of the embodiment of the present disclosure will be clearly and completely described in conjunction with the drawings of the specific embodiments of the present disclosure. Unless otherwise specified, the terms used herein have the usual meanings in the art. The same reference numerals in the drawings represent the same components.
[0034] In the description of the present disclosure, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.
[0035] Figure 1 and Figure 2 A schematic plan view of an operating mechanism according to an embodiment of the present disclosure is shown. Figure 1 The middle substrate is located at the first position. Figure 2 The middle base plate is located at the second position, and the housing is omitted. Figure 1 and Figure 2 As shown, the operating mechanism according to the present disclosure may include a base plate 1 , an actuating member 2 , a hook arm member 3 and a locking member 4 .
[0036] The substrate 1 according to the present disclosure may be pivotally mounted to the housing (not shown) relative to the housing so as to be in a first position (e.g. Figure 1 as shown) and a second position (as Figure 2 The substrate 1 can be pivoted between the second position and the first position, for example, the substrate 1 can be connected to other devices outside the operating mechanism, for example, an energy storage device (not shown), specifically, such as an opening spring and / or a closing spring. The operating mechanism of the present disclosure is intended to realize that the substrate 1 is placed in the first position by the actuator 2, for example, to realize charging of the energy storage device (not shown) outside the operating mechanism; and when the force outside the operating mechanism (such as, from the release of energy from the energy storage device) causes the substrate 1 to move from the second position to the first position, the substrate is not hindered by the actuator 2. Specifically, it is realized by the specific structure of the operating mechanism described below.
[0037] The actuator 2 is also pivotally mounted to the housing relative to the housing to pivot in a first direction and in a second direction opposite to the first direction, the first direction being in the direction of Figure 1 and 2 The second direction is shown as counterclockwise in Figure 1 and 2 The clockwise direction is shown as an example in the figure, and the orientation can be reversed according to the needs in actual application. The actuator 2 can be pivoted by, for example, a motor. In particular, the actuator 2 can coincide with the pivot axis of the substrate 1, and the pivoting of the actuator 2 in the first direction can, for example, be in the same direction as the pivoting of the substrate 1 from the first position to the second position, more particularly, synchronously pivoting (for example, by the hook arm member 3 and the locking member 4 as described later). Figure 1 and Figure 2As shown, the actuating member 2 may have a finger 21 protruding away from its pivot axis and contacting the hook arm member 2 via the finger 21 .
[0038] Combination Figure 1 and Figure 2 The hook arm member 2 may include a first arm 21 and a second arm 22, wherein the first arm 21 is used to cooperate with the actuator 2, and the second arm 22 is used to cooperate with the locking member 4. The first arm 21 may have a first side and a second side. In the present disclosure, the first side is designated as the side of the first arm 31 on which the finger 21 of the actuator 2 may be blocked when the actuator 2 pivots in the first direction. Figure 1 and Figure 2 The second side is designated as the side opposite to the first side, that is, when the actuator 2 is pivoted in the second direction, the finger 21 of the actuator 2 may be blocked on the side of the first arm 31. Figure 1 and Figure 2 3 is shown as the side of the first arm 31 that is further away from the second arm 32. Figure 1 In FIG. 1 , the finger 21 is shown as being located on the second side of the first arm; Figure 2 , the finger 21 is shown located on a first side of the first arm.
[0039] Furthermore, if Figure 1 and Figure 2 As shown, the hook arm member 3 may be provided with a sliding groove 33, and correspondingly, the base plate 1 may be provided with a pivot portion 11 extending into the sliding groove 33, and the pivot portion 11 may move in the sliding groove 33. For example, the sliding groove 33 may have the following Figure 1 and Figure 2 The hook arm member 3 can be pivoted and moved relative to the base plate 1. In addition, the relative pivoting and movement of the two can be achieved in other ways, for example, the pivot part is provided on the hook arm member, and the sliding groove is provided on the base plate.
[0040] For example, the sliding groove 33 may have a pivoting engagement edge 331 and a limiting edge 332. For example, the pivoting engagement edge 331 and the limiting edge 332 may be at two vertices of a substantially triangular shape. When the pivot portion 11 moves to abut against the pivoting engagement edge 332, as shown in FIG. Figure 1 and Figure 2 As shown, the hook arm member 1 can be pivoted relative to the base plate 1 around the pivot portion 11 by the pivoting engagement edge 331, for example Figure 3b and Figure 3c Different pivot angles of the hook arm 1 relative to the base plate 1 are shown.
[0041] In particular, the relative positions of the hook arm member 3, the actuating member 2 and the pivot portion 11 are arranged such that when the hook arm member 3 pivots relative to the base plate 1 around the pivot portion 11 via the pivoting engagement edge 331, the actuating member 11 is located between the first arm 31 and the second arm 32 to limit the pivoting range of the hook arm member 3. Thus, the hook arm member 3 is prevented from pivoting arbitrarily after being unlocked and being unable to return to its original position.
[0042] And when the pivot portion 11 abuts against the pivot engagement edge 331, the finger portion 21 of the actuator 2 can engage with the first arm 31 on the first side (eg Figure 3a as shown) or the second side (as shown Figure 3e ), thereby ensuring that the pivoting of the actuator 2 can be transmitted via the first arm 31, for example, to the base plate 1.
[0043] The relative positions of the substrate 1, the actuator 2 and the hook arm 3 can be set to be such that when the pivot portion 11 is located at the limiting edge 332, for example Figure 3d and Figure 3f As shown, the first arm 31 does not contact the actuator 2, in particular, does not contact the finger 21. Therefore, when the pivot portion 11 is located at the limit edge 332, the pivoting of the actuator 2 is not blocked or interfered by the first arm.
[0044] The hook arm member 3 is further configured such that: when the first arm 31 and the second arm 32 of the hook arm member 3 according to the present disclosure are not subjected to force (for example, the first arm 31 and the second arm 32 are separated from the actuator 2 and the locking member 4, respectively), especially when the operating mechanism according to the present disclosure is vertically installed, the hook arm member 3 moves relative to the substrate 1 under the action of gravity until the limiting edge 332 abuts against the pivot portion 11 and the hook arm member 3 comes to rest. Thus, it is ensured that when the hook arm member 3 and the locking member 4 are unlocked (described in detail later), the hook arm member 3 will not contact the actuator 2 at the final stop position, thereby preventing the relative movement of the hook arm member 3 and the actuator 2 from being hindered, that is, preventing the movement of the substrate 1 from the second position to the first position from being blocked by the actuator 2.
[0045] like Figure 1 and Figure 2 As shown, the operating mechanism according to the present disclosure further includes a locking member 4, which is pivotally mounted to the base plate 1. Specifically, the locking member 4 may include adjacent arc segments 41 and avoidance segments 42, and an extension arm 43.
[0046] The center of the arc segment 41 may coincide with the pivot axis of the locking member 4, and the distance between the point on the avoidance segment 42 and the pivot axis is less than or equal to the radius of the arc segment 41. Thus, for example, when the hook arm member 3 has a movement tendency of the second arm 32 toward the pivot axis of the locking member 4, if the arc segment 41 abuts against the second arm 32, the relative position of the second arm 32 and the pivot axis of the locking member 4 remains unchanged, thereby blocking the movement tendency. Figure 3a , Figure 3b , Figure 3e as well as Figure 3f As shown, that is, the second arm 32 is locked with the locking member 4; if the avoidance section 42 is opposite to the second arm 32, the hook arm member 3 pivots through the avoidance section 42, so that the second arm 32 is separated from the locking member 4, as shown Figure 3c As shown, the second arm 32 is unlocked from the locking member 4 .
[0047] In particular, the hook arm member 3 and the locking member 4 can be arranged so that when the second arm 32 abuts against the arc section 41, the force of the second arm 32 provides a pivoting torque to the locking member 4, and the pivoting torque causes the locking member to have a movement tendency of avoiding the section 42 away from the second arm 32, so that the locking of the hook arm member 3 and the locking member 4 is tighter, which is beneficial to the locking stability.
[0048] By locking the second arm 32 and the locking member 4, when the substrate 1 is in the first position, when the finger portion 21 of the actuator 2 abuts against the first arm 31 at the first side of the first arm 31, the hook arm member 3 can be made stationary relative to the substrate 1, thereby, the pivoting movement of the actuator 2 in the first direction can drive the hook arm member 3, the locking member 4 and the substrate 1 to move together, so that the substrate 1 moves from the first position (such as Figure 3a ) moves to the second position (such as Figure 3b ).
[0049] The extension arm 43 is as follows Figure 1 and Figure 2 As shown, it extends toward the limiting elastic member 5 and can contact and abut against the limiting elastic member 5.
[0050] One end of the limiting elastic member 5 is fixed to the housing, and the other end is a free end, for example Figure 4 The form shown may be a torsion spring. By making the free end relatively move relative to the fixed end, the position-limiting elastic member 5 may be elastically deformed, thereby storing elastic potential energy, and the elastic deformation of the position-limiting elastic member 5 may be used to realize the actuation function and the biasing function.
[0051] In addition, if Figure 4 As shown, the free end of the limiting elastic member 5 can be a semi-enclosed hook shape, or can be other suitable shapes, as long as the following conditions are met: the free end can only block the hook arm member 3 in a single direction (for example, the direction in which the hook arm member 3 moves toward the limiting elastic member 5), thereby achieving the biasing of the hook arm member 3, and the free end can only block the extension arm 43 in the opposite direction.
[0052] Specifically, the position of the limiting elastic member 5 relative to the substrate can be set as follows: when the substrate 1 is in the first position, the hook arm member 3 is biased so that the second arm 32 abuts against the locking member 4, and the pivot portion 11 abuts against the pivoting matching edge 331, as shown in FIG. Figure 1As shown. This ensures that the finger 21 of the actuator 2 can be aligned with the first arm 31 on the first side (such as Figure 3a As shown in the figure, the first arm 31 abuts against the substrate 1 so that the pivoting of the actuator 2 can be transmitted through the first arm 31, for example, to the substrate 1.
[0053] Furthermore, when the substrate 1 moves to the second position and leaves the first position, the hook arm member 3 driven by the substrate 1 can be separated from the limiting elastic member 5, and is no longer constrained or blocked by the limiting elastic member 5, which enables the hook arm member 3 to smoothly disengage from the locking member 4 when the substrate 1 moves to the second position.
[0054] When the substrate 1 moves from the first position to the second position, the extension arm 43 of the locking member 4 driven by the substrate 1 abuts against the free end of the limiting elastic member 5 and causes the limiting elastic member 5 to undergo elastic deformation. After the substrate 1 moves to the second position, the limiting elastic member 5 is deformed to the maximum extent, thereby releasing elastic potential energy, thereby causing the extension arm 43 to move, so that the locking member 4 pivots relative to the substrate 1 (from Figure 3b The state of the pivot to Figure 3c State), and then the avoidance section 42 of the locking member 4 is opposite to the second arm 32, causing the locking member 4 to separate from the second arm 32, that is, unlocking, such as Figure 2 As shown. It is ensured that the hook arm member 3 and the locking member 4 are unlocked only after the base plate 1 is placed in the second position by the locked hook arm member 3 and the locking member 4.
[0055] Further, when the locking member 4 is separated from the second arm 32, if the finger portion 21 of the actuator 2 abuts against the first arm 1 at the first side of the first arm 31, especially when the hook arm member 3 is separated from the limiting elastic member 5, the abutment may cause the hook arm member 3 to pivot relative to the base plate 1 until the first arm 31 is separated from the actuator 2, such as Figure 3c As shown. For example, when the substrate 1 moves from the second position to the first position, the first arm 31 abuts against the finger 21 of the actuator 2 at its first side, providing the hook arm member 3 with a torque around the pivot portion 11. At this time, since the hook arm member 3 is not constrained by the position-limiting elastic member 5, the torque causes the first arm 31 to move toward its second side away from the finger 21 of the actuator 2. Thus, it is ensured that when unlocking, even if the finger 21 of the actuator 2 is adhered to the first arm 1 at the first side of the first arm 31 due to factors such as low temperature, as long as the substrate 1 moves from the second position to the first position, the actuator 2 will inevitably be separated from the first arm 31, so that the movement is not blocked by the actuator 2.
[0056] In addition, the operating mechanism according to the present disclosure further includes a biasing member 6, which is in the form of a tension spring, one end of which is fixed to the base plate 1, and the other end of which is fixed to the locking member 4, such as Figure 4The biasing member can bias the locking member so that when the pivot portion 11 abuts against the pivoting mating edge 331, the second arm 32 can abut against the arc segment 41 of the locking member 4, so that the hook arm member 3 and the locking member 4 are locked. When the above-mentioned limiting elastic member 5 releases the elastic potential energy so that the locking member 4 pivots relative to the substrate 1 (from Figure 3b Status Pivot to Figure 3c state), thereby causing the locking member 4 to be unlocked from the second arm 32, the biasing member 6 can pull and reset the locking member 4, thereby Figure 3d Status reset to Figure 3e state.
[0057] Next, combine Figure 3a-3f The operation process of the operating mechanism according to the present disclosure is described in detail, wherein the limiting elastic member 5 is omitted and the locking member 4 is shown with a simplified symbol.
[0058] like Figure 3a As shown, in this state, the substrate 1 is located in the first position, the finger portion 21 of the actuator 2 abuts against the first arm 31 at the first side of the first arm 31, the pivot portion 11 is located at the pivoting matching edge 331, and the second arm 32 abuts against the arc section of the locking member 4. As a result, the hook arm member 3 is locked with the locking member 4, the hook arm member 3 can be relatively still relative to the substrate 1, and the pivoting movement of the actuator 2 in the first direction can drive the hook arm member 3, the locking member 4 and the substrate 1 to move together, so that the substrate 1 can be moved from the first position (as shown in FIG. Figure 3a ) to the second position (such as Figure 3b )sports.
[0059] like Figure 3b As shown, in this state, the substrate 1 moves to the second position, the finger portion 21 of the actuating member 2 abuts against the first arm 31 at the first side of the first arm 31, the pivot portion 11 is located at the pivoting matching edge 331, the second arm 32 abuts against the arc section of the locking member 4, and the hook arm member 3 is separated from the limiting elastic member 5. Therefore, the locking of the hook arm member 3 and the locking member 4 has not been released, but in this state, the extension arm 43 of the locking member 4 driven by the substrate 1 abuts against the free end of the limiting elastic member 5 and causes the limiting elastic member 5 to undergo elastic deformation to the maximum extent, thereby releasing the elastic potential energy, thereby causing the extension arm 43 to move, causing the locking member 4 to pivot relative to the substrate 1, that is, from Figure 3b The status of Figure 3c The state of the pivot.
[0060] exist Figure 3b The status of Figure 3cDuring the state change process, the locking member 4 pivots relative to the base plate 1, so that the avoidance section 42 of the locking member 4 is opposite to the second arm 32, causing the locking member 4 to separate from the second arm 32, that is, unlocking. When unlocking, even if the finger portion 21 of the actuator 2 is adhered to the first arm 1 on the first side of the first arm 31 due to factors such as low temperature, as long as the finger portion 21 of the actuator 2 abuts against the first arm 1 on the first side of the first arm 31, for example, the base plate 1 moves from the second position to the first position, which provides a torque around the pivot portion 11 for the hook arm member 3 (in Figure 3b In the figure, the hook arm member 3 is in the counterclockwise direction. At this time, since the hook arm member 3 is not constrained by the limiting elastic member 5, the torque causes the first arm 31 to move toward its second side away from the finger portion 21 of the actuating member 2, that is, the hook arm member 3 pivots to Figure 3c In the state shown, the separation of the first arm 31 and the actuator 2 is ensured.
[0061] like Figure 3c As shown, in this state, the base plate 1 is located at the second position, the first arm 31 is separated from the actuating member 2, the second arm 32 is separated from the locking member 4, and the pivoting of the hook arm member 3 is blocked and limited by the actuating member 2 (the second arm 32 is blocked and limited by the actuating member 2). The limiting elastic member 5 abuts against the extension arm 41 of the locking member 4, so that the biasing member 6 is stretched and deformed.
[0062] Under the action of gravity, since the hook arm member 3 is not constrained by the actuating member 2, the limiting elastic member 3 and the locking member 4, the hook arm member 3 will move relative to the base plate 1, and finally stop by the limiting edge 332 abutting against the pivot portion 11. Figure 3d In this state, the hook arm member 3 does not contact the actuating member 2 in the stop position (the limiting edge 332 abuts against the pivot portion 11 ), thereby not causing any hindrance to the relative movement between the hook arm member 3 and the actuating member 2 .
[0063] When the substrate 1 is moved from the second position (such as Figure 3d ) pivots to a first position (eg Figure 3e ), the locking member 4 and the limiting elastic member 5 (not shown) change from abutting to separating, and the biasing member 6 resets and pulls the locking member 4 to reset until Figure 3e The hook arm member 3 and the limiting elastic member 5 (not shown) change from being separated to being in contact with each other, so that the hook arm member 3 is blocked by the limiting elastic member 5 and moves relative to the base plate 1 until the hook arm member 3 is blocked by the limiting elastic member 5 and moves relative to the base plate 1. Figure 3e As shown, the second arm 32 abuts against the arc section 41 of the locking member 4 and the pivot portion 11 moves from the limiting edge 332 to the pivoting engagement edge 331, so that the hook arm member 3 and the base plate 1 are relatively stationary. Figure 3e In the illustrated state, the finger 21 of the actuator 2 is located on the second side of the first arm 31 .
[0064] In order to make the finger 21 of the actuator 2 abut against the first arm 31 at the first side (ie, return to the position as shown in FIG. Figure 3a In the state shown in the figure, the actuator 2 can be pivoted in the second direction. In the pivoting process, the finger 21 of the actuator 2 abuts against the first arm 31 at the second side of the first arm 31 and moves toward the first side of the first arm 31. Since the second arm 32 abuts against the locking member 4 and the hook arm member 3 is constrained by the limiting elastic member, the actuator 2 drives the hook arm member 3 to overcome the limiting elastic member 5 and move relative to the substrate 1, that is, the hook arm member 3 moves from Figure 3e The state changes to Figure 3f Thus, the actuator 2 is avoided, so that the finger 21 of the actuator 2 can move in the second direction to the first side of the first arm 1, that is, back to the state. Figure 3a state, thus forming a complete closed loop of operating status.
