Description

Technical Field

[0001] The present application relates to the technical field of electrical equipment, and in particular to an operating handle and a motor protector. Background Art

[0002] A motor protector, also known as a motor circuit breaker or motor protection device, is a specialized protection device installed on the motor control panel. It promptly disconnects the power supply to prevent damage to the motor when faults such as overcurrent, undercurrent, phase failure, stall, overheating, or motor overload occur.

[0003] A motor protector typically consists of an operating handle, a connecting rod, and a motor protector body. The operating handle is connected to the motor protector body via the connecting rod. The motor protector body is also connected to the motor. Rotating the operating handle controls the motor protector body to close or open, thereby powering the motor on or off.

[0004] Motor protectors are usually installed in power distribution cabinets. In the prior art, motor protectors cannot be accurately assembled when installed in power distribution cabinets, resulting in low assembly efficiency and easy damage to the operating handle or the motor protector body. Utility Model Content

[0005] The present application provides an operating handle and a motor protector, which can facilitate the accurate and efficient installation of the motor protector in the power distribution cabinet, reducing the possibility of damage to the operating handle or the motor protector body.

[0006] In the first aspect, the present application provides an operating handle, which is connected to the Mabao body through a connecting rod. The operating handle includes a shell, a positioning core and a locking member. The shell is provided with a limiting structure. The positioning core is installed in the shell, and the positioning core is used to connect with the connecting rod, and can rotate relative to the shell under the drive of the connecting rod. The locking member includes a connecting portion, a locking portion and an abutting portion, the connecting portion is rotatably connected to the positioning core, the locking portion and the abutting portion are located on different sides of the connecting portion, the locking portion is used to cooperate with the limiting structure, and the abutting portion is used to cooperate with the connecting rod.

[0007] During the first period, the locking portion can lock with the limiting structure to restrict the positioning core from rotating relative to the housing. During the second period, the abutment portion, pushed by the connecting rod, drives the locking member to rotate relative to the positioning core, thereby releasing the lock between the locking portion and the limiting structure and allowing the positioning core to rotate relative to the housing. The first period corresponds to the period when the connecting rod is not connected to the positioning core, and the second period corresponds to the period when the connecting rod is connected to the positioning core.

[0008] Through the above solution, in the first period, the locking portion of the locking member is locked with the limiting structure of the shell. Since the position of the shell remains unchanged, the position of the locking member also remains unchanged. That is to say, in the first period, the positioning core is locked in the initial state through the cooperation between the locking member and the shell, and the positioning core cannot rotate relative to the shell. In this way, even if the knob exposed outside the cabinet door is accidentally touched, if the positioning core cannot rotate relative to the shell, the knob will also not be able to rotate relative to the shell, so that the operating handle can be maintained in the initial state, and will not affect the installation of the connecting rod in the distribution cabinet. In this way, the motor protector can be accurately and efficiently installed in the distribution cabinet, which improves the efficiency of installing the motor protector in the distribution cabinet.

[0009] When the motor protector is accurately installed in the distribution cabinet, the operator does not need to repeatedly adjust the position of the connecting rod or turn the knob to debug, thereby reducing the possibility of damage to the operating handle or the motor protector body. The positioning core in the operating handle provided by the present application can also be unlocked from the housing during the second period, facilitating normal operation of the operating handle.

[0010] In one possible design, the locking member includes a first plate and a second plate connected to each other, with a non-zero angle between the first plate and the second plate. The connecting portion is provided at the junction of the first and second plates, the locking portion is provided at an end of the first plate away from the second plate, and the abutting portion is provided at an end of the second plate away from the first plate.

[0011] With this solution, the connecting portion is positioned between the locking portion and the abutting portion. Thus, when the connecting rod pushes against the abutting portion, causing the locking member to rotate relative to the positioning core, the locking member only needs to rotate a small angle to release the locking portion from the retaining structure. This reduces the space required for the locking member to rotate, ensuring that the placement of the locking member does not affect the existing layout of other components in the operating handle.

[0012] In a possible design, the limiting structure is a mounting hole provided on the shell, and the locking portion is a boss provided at one end of the first plate away from the second plate toward the mounting hole, and the boss is adapted to the mounting hole.

[0013] With the above solution, during the first period, the boss can extend into the mounting hole and lock with the mounting hole, thereby fixing the position of the locking member relative to the housing. This, in turn, fixes the position of the positioning core connected to the locking member relative to the housing, thereby restricting rotation of the positioning core relative to the housing. During the second period, the connecting rod pushes against the abutment portion, causing the boss to disengage from the mounting hole when the locking member rotates relative to the positioning core, thereby releasing the lock between the locking member and the housing and allowing the positioning core connected to the locking member to rotate freely relative to the housing.

[0014] In a possible design, a rib is provided on one side of the boss for cooperating with the hole wall of the mounting hole.

[0015] Through the above solution, a rib can replace the boss to engage with the wall of the mounting hole. Because the area of the rib's side engaging the wall of the mounting hole is smaller than the area of the boss's side engaging the wall of the mounting hole, this arrangement ensures that the locking member and the housing are locked during the first period to limit rotation of the positioning core relative to the housing, while reducing the friction between the locking member and the housing during the second period when they are unlocked. This reduces wear on the location where the locking member and the housing interlock, extending the service life of the locking member and the housing, and improving the reliability of subsequent locking of the locking member and the housing.

[0016] In one possible design, the positioning core has a connecting hole for inserting a connecting rod to connect to the positioning core. A first movable groove is provided in the wall of the connecting hole on the side closest to the retaining structure, communicating with the connecting hole. During a first period, the abutment portion is located within the connecting hole. During a second period, the abutment portion is pushed by the connecting rod and rotates from the connecting hole into the first movable groove.

[0017] With the above solution, when the locking member rotates relative to the positioning core, the second plate provided with the abutting portion can rotate freely in the first movable groove without interfering with the hole wall on one side of the connecting hole close to the limiting structure.

[0018] In one possible design, a second movable groove is provided on a side of the positioning core facing the first plate, the second movable groove being connected to the first movable groove. In the second period, when the locking member rotates relative to the positioning core, a portion of the first plate near the connection rotates in the second movable groove.

[0019] With the above solution, when the locking member rotates relative to the positioning core in the second period, the portion of the first plate near the connection can rotate freely in the second movable groove without interfering with the side of the positioning core facing the first plate.

[0020] In one possible design, a first slot is provided on the slot wall of the first movable slot close to the limiting structure, a rotating shaft is provided on the slot wall of the first slot, and the connecting part is a clamping hoop provided at the connection, which extends into the first slot and is sleeved on the rotating shaft.

[0021] With the above solution, the clamp is inserted into the first slot and sleeved on the rotating shaft, thereby realizing the rotational connection of the locking member on the positioning core. The connection method is simple and reliable.

[0022] In a possible design, there are multiple clamps, and the multiple clamps are arranged at intervals.

[0023] Through the above scheme, multiple clamps can be arranged at intervals at the connection between the first plate and the second plate. In this way, multiple clamps can cooperate with different positions of the rotating shaft, so that the force at the rotating connection between the locking piece and the positioning core is uniform, further increasing the reliability of the rotating connection between the locking piece and the positioning core.

[0024] In a possible design, the first plate, the second plate, the connecting portion, the locking portion and the abutting portion are integrally formed.

[0025] Through the above solution, the assembly process of each part of the locking member can be saved, and the structural strength of the locking member can be easily ensured.

[0026] In a second aspect, the present application provides a motor protector, comprising a motor protector body, a connecting rod and the operating handle of the first aspect, wherein the motor protector body and the operating handle are connected by the connecting rod.

[0027] The beneficial effects of the motor protector provided in the second aspect and each possible design of the second aspect can be referred to the beneficial effects brought about by the first aspect and each possible implementation method of the first aspect, and will not be repeated here.

[0052] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0053] Figure 1 This is a schematic diagram of the combined structure of an operating handle provided in an embodiment of the present application at one viewing angle. The present application provides a motor protector, which includes a motor protector body, a connecting rod and a motor protector. Figure 1 The operating handle 100 shown. The horse protection body and the operating handle 100 are connected by a connecting rod.

[0054] The main body of the Mabao can be a circuit breaker. The connecting rod can be in the shape of a quadrangular prism or other possible shapes.

[0055] Figure 2 This is a partial structural exploded diagram of an operating handle provided in an embodiment of the present application, combined with Figure 1 and Figure 2 , the operating handle 100 includes a positioning core 110 .

[0056] One end of the connecting rod is connected to the positioning core 110, and the other end of the connecting rod is connected to the Ma Bao body, so as to realize the connection between the operating handle 100 and the Ma Bao body through the connecting rod. Among them, the specific structure of the operating handle 100 will be described in detail later and will not be expanded here.

[0057] Motor protectors are typically installed in power distribution cabinets. The operating handle 100 is typically mounted on the cabinet door, partially exposed outside the door, while the motor protector itself resides inside the cabinet. After connecting the operating handle 100 to the motor protector via a connecting rod, the operator can control the motor protector to close or open the circuit breaker by rotating the operating handle 100 from outside the cabinet.

[0058] The motor protector is also connected to the motor, allowing the motor protector to be connected to the motor's circuit. This allows the motor protector to be connected to the motor circuit when the motor protector is closed, allowing the motor to operate normally. Conversely, when the motor protector is open, the motor circuit is disconnected, de-energizing the motor and stopping operation. This allows the motor protector to control and protect the motor circuit.

[0059] The specific structure of the operating handle 100 provided in this application will be described in detail below with reference to the accompanying drawings.

[0060] Figure 3 This is a schematic structural diagram of a housing provided in an embodiment of the present application. Figure 4 This is a schematic diagram of the structure of a locking member provided in an embodiment of the present application, combined with Figures 1 to 4The operating handle 100 provided in the present application includes a shell 120, a positioning core 110 and a locking member 130. Among them, the shell 120 is provided with a limiting structure 121. The positioning core 110 is installed in the shell 120, and the positioning core 110 is used to connect with the connecting rod, and can rotate relative to the shell 120 under the drive of the connecting rod. The locking member 130 includes a connecting portion 131, a locking portion 132 and an abutting portion 133. The connecting portion 131 is rotatably connected to the positioning core 110, and the locking portion 132 and the abutting portion 133 are located on different sides of the connecting portion 131. The locking portion 132 is used to cooperate with the limiting structure 121, and the abutting portion 133 is used to cooperate with the connecting rod.

[0061] The housing 120 is the basic structure of the operating handle 100. It has mounting locations for the knob 140 and the positioning core 110, allowing the knob 140 and the positioning core 110 to be mounted on the housing 120. A retaining structure 121 on the housing 120 can be located near the locking member 130 to facilitate engagement between the locking member 130 and the retaining structure 121.

[0062] like Figure 2 As shown, the positioning core 110 is provided with a connection hole 111 for the connecting rod to extend into. The shape of the connection hole 111 is adapted to the shape of the connecting rod. For example, when the connecting rod is in the shape of a quadrangular prism, the connection hole 111 can be a square hole. Once the connecting rod is inserted into the connection hole 111 and properly installed, the connection between the connecting rod and the positioning core 110 is achieved.

[0063] The positioning core 110 is also connected to the knob 140. After the connecting rod is connected to the positioning core 110, rotating the knob 140 can drive the positioning core 110 and the connecting rod to rotate relative to the housing 120. Then, the connecting rod can drive the Ma Bao body to close or open the switch.

[0064] like Figure 4 As shown, the locking member 130 includes a connecting portion 131, a locking portion 132 and an abutting portion 133. The connecting portion 131 can be rotatably connected to the positioning core 110 by means of hole-axis matching, or hinge connection, and the position of the connecting portion 131 is the position of the rotation axis of the locking member 130. The locking portion 132 can be locked to the limiting structure 121, and the locking portion 132 can also be unlocked from the limiting structure 121. The abutting portion 133 is located on the moving path of the connecting rod, and when the connecting rod is installed to the positioning core 110, it can push the abutting portion 133, so that the abutting portion 133 drives the locking member 130 to rotate as a whole relative to the positioning core 110.

[0065] The following combination Figures 5 to 9 The working principles of the operating handle 100 at different time periods are introduced in detail.

[0066] Figure 5 This is a schematic diagram of the combined structure of an operating handle provided in an embodiment of the present application from another perspective. Figure 6 yes Figure 5 Cross-sectional view along section AA when the middle locking part is locked with the limiting structure, Figure 7 yes Figure 6 An enlarged view of part B in the figure. Figure 6 and Figure 7 As shown, in the first period, the locking portion 132 can be locked with the limiting structure 121 to limit the rotation of the positioning core 110 relative to the housing 120 .

[0067] Figure 8 yes Figure 5 A cross-sectional view along section AA when the locking of the middle locking portion and the limiting structure is released. Figure 9 yes Figure 8 The enlarged view of part C is as follows: Figure 8 and Figure 9 As shown, in the second period, the abutting portion 133 is pushed by the connecting rod, driving the locking member 130 to rotate relative to the positioning core 110 to release the lock between the locking portion 132 and the limiting structure 121, so that the positioning core 110 can rotate relative to the housing 120.

[0068] The first period corresponds to the period when the connecting rod is not connected to the positioning core 110, during which the positioning core 110 is in an initial state. The second period corresponds to the period when the connecting rod is connected to the positioning core 110, and after the connecting rod is properly installed in the positioning core 110, the positioning core 110 is in an operating state.

[0069] exist Figure 6 and Figure 7 In the first period, the locking portion 132 is locked with the limiting structure 121. Since the limiting structure 121 is provided on the housing 120, and the position of the housing 120 remains unchanged during the use of the operating handle 100, the position of the limiting structure 121 remains unchanged. Based on this, when the locking portion 132 is locked with the limiting structure 121, the position of the locking portion 132 also remains unchanged. As a result, the overall position of the locking member 130 including the locking portion 132 relative to the housing 120 remains unchanged. In other words, in the first period, the positioning core 110 is locked in the initial state by the cooperation between the locking member 130 and the housing 120, and the positioning core 110 cannot rotate relative to the housing 120.

[0070] In the second period, when the connecting rod is installed to the positioning core 110, the connecting rod moves a certain distance along the connecting hole 111 and then abuts against the abutting portion 133, and pushes the abutting portion 133. Under the push of the connecting rod, the abutting portion 133 drives the locking member 130 to rotate a certain angle relative to the positioning core 110, and then the locking portion 132 and the limiting structure 121 are released. Figure 8 and Figure 9After the locking portion 132 and the limiting structure 121 are released, the locking member 130 no longer cooperates with the housing 120 , and the positioning core 110 and the locking member 130 can freely rotate relative to the housing 120 .

[0071] In the embodiment of the present application, during the first period, the locking portion 132 of the locking member 130 is locked with the limiting structure 121 of the housing 120. Since the position of the housing 120 remains unchanged, the position of the locking member 130 also remains unchanged. That is to say, during the first period, the positioning core 110 is locked in the initial state through the cooperation between the locking member 130 and the housing 120, and the positioning core 110 cannot rotate relative to the housing 120. In this way, even if the knob 140 exposed outside the cabinet door is accidentally touched, if the positioning core 110 cannot rotate relative to the housing 120, the knob 140 will also not be able to rotate relative to the housing 120, so that the operating handle 100 can be maintained in the initial state, and will not affect the installation of the connecting rod in the power distribution cabinet. In this way, the motor protector can be accurately and efficiently installed in the power distribution cabinet, which improves the efficiency of installing the motor protector in the power distribution cabinet.

[0072] When the motor protector can be accurately installed in the distribution cabinet, the operator does not need to adjust the position of the connecting rod multiple times or turn the knob 140 multiple times for debugging, thereby reducing the possibility of damage to the operating handle 100 or the motor protector body.

[0073] In addition, during the second period when the connecting rod is connected to the positioning core 110, the pushing portion is pushed by the connecting rod, which can drive the locking member 130 to rotate relative to the positioning core 110, so as to release the lock of the locking portion 132 and the limiting structure 121, so that the positioning core 110 can rotate relative to the shell 120, thereby realizing normal operation of the operating handle 100.

[0074] It can be seen that the positioning core in the operating handle 100 provided in the present application can not only maintain its initial state in the first period and cannot rotate relative to the shell 120 to facilitate the accurate installation of the motor protector to the distribution cabinet, but can also release the lock with the shell 120 in the second period to facilitate the normal operation of the operating handle 100.

[0075] Please continue to refer to Figure 4 In some embodiments, the locking member 130 may include a first plate 134 and a second plate 135 connected to each other, with a non-zero angle between the first plate 134 and the second plate 135. The connecting portion 131 is provided at the connection between the first plate 134 and the second plate 135, the locking portion 132 is provided at an end of the first plate 134 away from the second plate 135, and the abutting portion 133 is provided at an end of the second plate 135 away from the first plate 134.

[0076] The angle between the first plate 134 and the second plate 135 can be an acute angle, a right angle, or an obtuse angle. The angle between the first plate 134 and the second plate 135 can be determined based on actual conditions. As long as the locking portion 132 is locked with the limiting structure 121, the abutting portion 133 can be pushed by the connecting rod to drive the locking member 130 to rotate relative to the positioning core 110, thereby releasing the lock between the locking portion 132 and the limiting structure 121. This embodiment of the present application does not limit the angle between the first plate 134 and the second plate 135.

[0077] Figure 4 In the locking member 130 shown in FIG, the angle between the first plate 134 and the second plate 135 is an obtuse angle, but it does not constitute a limitation to the technical solution of the present application.

[0078] The first plate 134, the second plate 135, the connecting portion 131, the locking portion 132, and the abutting portion 133 can be formed separately and then assembled by plugging, screwing, or the like to form the locking member 130. The first plate 134, the second plate 135, the connecting portion 131, the locking portion 132, and the abutting portion 133 can also be formed integrally to save the assembly steps of the various parts of the locking member 130.

[0079] Through the above arrangement, the connecting portion 131 is located between the locking portion 132 and the abutting portion 133. Thus, when the connecting rod pushes against the abutting portion 133, causing the locking member 130 to rotate relative to the positioning core 110, the locking member 130 only needs to rotate a small angle to release the lock between the locking portion 132 and the limiting structure 121. This saves space when the locking member 130 rotates, ensuring that the arrangement of the locking member 130 does not affect the original layout of other components in the operating handle 100.

[0080] The retaining structure 121 and the locking portion 132 can have various structural forms. For example, in some embodiments, the retaining structure 121 can be a bar disposed on the housing 120 toward the first plate 134, and the locking portion 132 can be a slot disposed at one end of the first plate 134 away from the second plate 135. The bar fits into the slot.

[0081] During the first period, the inserting strip is inserted into the insertion slot and locked therewith. The position of the locking member 130 relative to the housing 120 remains unchanged, and the position of the positioning core 110 relative to the housing 120 also remains unchanged, and the positioning core 110 cannot rotate relative to the housing 120.

[0082] In the second period, the connecting rod pushes the abutment portion 133, so that when the locking member 130 rotates relative to the positioning core 110, the insertion slot disengages from the insertion strip, the locking portion 132 and the limiting structure 121 are unlocked, and the positioning core 110 can rotate relative to the housing 120.

[0083] In other embodiments, combined Figure 3 and Figure 4 The limiting structure 121 can be a mounting hole provided on the housing 120, and the locking portion 132 can be a boss provided toward the mounting hole at one end of the first plate 134 away from the second plate 135. The boss is adapted to the mounting hole.

[0084] The mounting hole can be a hole of any shape, such as a round hole or a square hole. The mounting hole can be a hole specifically provided on the housing 120 to facilitate mating with the boss. Of course, the mounting hole can also be a hole already on the housing 120 that is used to achieve other functions, so that the mounting hole can be reused while still achieving the effect of mating with the boss.

[0085] If the mounting hole is a square hole, the boss can be a square boss, an arcuate boss, a circular boss, etc. If the mounting hole is a circular hole, the boss can be an arcuate boss, a circular boss, etc. As long as the boss can be locked with the mounting hole during the first period and can be released from the mounting hole during the second period, the embodiments of the present application do not limit the shapes of the boss and the mounting hole.

[0086] In this embodiment, the limiting structure 121 is a mounting hole provided in the housing 120, and the locking portion 132 is a boss provided on the first plate 134, which is adapted to fit within the mounting hole. With this arrangement, during a first period, the boss can extend into the mounting hole and lock with it, thereby fixing the position of the locking member 130 relative to the housing 120. This, in turn, fixes the position of the positioning core 110 connected to the locking member 130 relative to the housing 120, thereby limiting rotation of the positioning core 110 relative to the housing 120. During a second period, the connecting rod pushes against the abutment portion 133, causing the boss to disengage from the mounting hole when the locking member 130 rotates relative to the positioning core 110, thereby releasing the lock between the locking member 130 and the housing 120 and allowing the positioning core 110 connected to the locking member 130 to rotate freely relative to the housing 120.

[0087] On the basis of the above embodiments, further, in some embodiments, such as Figure 3 and Figure 4 As shown, a rib 1321 may be provided on one side of the boss for cooperating with the hole wall of the mounting hole.

[0088] The number of ribs 1321 may be one or more. When there is only one rib 1321, this rib 1321 may be located anywhere on the side of the boss that mates with the wall of the mounting hole. When there are multiple ribs 1321, multiple ribs 1321 may be spaced apart on the side of the boss that mates with the wall of the mounting hole. This application does not limit the number of ribs 1321 or the locations of the ribs 1321.

[0089] A rib 1321 is provided on the side of the boss that mates with the wall of the mounting hole, allowing rib 1321 to replace the boss in mating with the wall of the mounting hole. Because the area of the side of rib 1321 that mates with the wall of the mounting hole is smaller than the area of the side of the boss that mates with the wall of the mounting hole, this arrangement ensures that locking member 130 is locked to housing 120 during the first period, thereby limiting rotation of positioning core 110 relative to housing 120, while reducing the friction between locking member 130 and housing 120 during the second period when the locking member 130 and housing 120 are unlocked. This reduces wear at the point where locking member 130 and housing 120 are locked together, extending the service life of locking member 130 and housing 120, and improving the reliability of subsequent locking of locking member 130 and housing 120.

[0090] Figure 10 This is a schematic diagram of the structure of a positioning core provided in an embodiment of the present application. In some embodiments, such as Figure 6 、 Figure 7 and Figure 10 As shown, a first movable groove 112 can be provided on the wall of the connecting hole 111 near the limiting structure 121. The first movable groove 112 is connected to the connecting hole 111. During a first period, the abutment portion 133 is located within the connecting hole 111. During a second period, the abutment portion 133 is pushed by the connecting rod and rotates from the connecting hole 111 into the first movable groove 112.

[0091] The structure of the connection hole 111 has been introduced above and will not be repeated here.

[0092] The size of the first movable groove 112 can be set according to the size of the second plate 135 on which the abutting portion 133 is provided and the rotation angle of the locking member 130 relative to the positioning core 110 .

[0093] A first movable groove 112 is provided on the wall of the connecting hole 111 on the side close to the limiting structure 121, and the first movable groove 112 is in communication with the connecting hole 111. Thus, when the locking member 130 rotates relative to the positioning core 110, the second plate 135 provided with the abutting portion 133 can rotate freely within the first movable groove 112 without interfering with the wall of the connecting hole 111 on the side close to the limiting structure 121.

[0094] Please continue to refer to Figure 4 and Figure 10 In some embodiments, a second movable groove 113 may be provided on the side of the positioning core 110 facing the first plate 134. The second movable groove 113 is connected to the first movable groove 112. During the second period, when the locking member 130 rotates relative to the positioning core 110, the portion of the first plate 134 near the connection rotates within the second movable groove 113.

[0095] The size of the second movable groove 113 can be set according to the size of the first plate 134 and the rotation angle of the locking member 130 relative to the positioning core 110 .

[0096] A second movable groove 113 is provided on the side of the positioning core 110 facing the first plate 134, and the second movable groove 113 is connected to the first movable groove 112. Thus, when the locking member 130 rotates relative to the positioning core 110 during the second period, the portion of the first plate 134 near the connection can rotate freely within the second movable groove 113 without interfering with the side of the positioning core 110 facing the first plate 134.

[0097] In summary, whether the present application sets the first movable groove 112 on the hole wall of the connecting hole 111 on the side close to the limiting structure 121, or sets the second movable groove 113 on the side of the positioning core 110 facing the first plate 134, it can provide space for the locking member 130 to rotate relative to the positioning core 110. On the one hand, it can reduce the possibility of interference between the locking member 130 and the hole wall on the side of the connecting hole 111 close to the limiting structure 121, and reduce the possibility of interference between the locking member 130 and the side of the positioning core 110 facing the first plate 134. On the other hand, it facilitates the reasonable setting of the size of the locking member 130, so as to reduce the possibility that the setting of the locking member 130 will affect the original layout of other structural components in the operating handle 100.

[0098] Combine Figure 4 、 Figures 6 to 10 In some embodiments, the first movable slot 112 may have a first slot 1121 disposed on the side of the slot wall near the limiting structure 121, and the first slot 1121 may have a rotating shaft 114 disposed on the slot wall. The connecting portion 131 may be a clamp provided at the connection, extending into the first slot 1121 and sleeved on the rotating shaft 114.

[0099] The number of the first slots 1121 can be one or more. Figure 10 In the embodiment, the number of the first slots 1121 is two.

[0100] The first slot 1121 may be formed by hollowing out a small area of the slot wall of the first movable slot 112 on the side close to the limiting structure 121. In this case, the rotating shaft 114 may be formed by the remaining structure around the first slot 1121 after the first slot 1121 is provided on the slot wall of the first movable slot 112 on the side close to the limiting structure 121.

[0101] The first slot 1121 can also be formed by hollowing out a large area of the slot wall of the first movable slot 112 on the side near the limiting structure 121. In this case, the rotating shaft 114 can be an axis structure that is subsequently connected to the slot wall of the first slot 1121 by plugging or snapping. This application does not limit the formation method of the rotating shaft 114.

[0102] The clamp has an opening, and the connecting portion 131 can be sleeved on the rotating shaft 114 through the opening.

[0103] The number of clamps can be one or more. If there are multiple clamps, each of which extends into the first slot 1121 and is mounted on the rotating shaft 114, the reliability of the rotational connection between the locking member 130 and the positioning core 110 can be increased. When there are multiple clamps, the multiple clamps can be spaced apart at the connection between the first plate 134 and the second plate 135. In this way, the multiple clamps can be matched with different positions on the rotating shaft 114, ensuring uniform force at the rotational connection between the locking member 130 and the positioning core 110, further increasing the reliability of the rotational connection between the locking member 130 and the positioning core 110.

[0104] A first slot 1121 is provided in the wall of the first movable slot 112 on the side near the retaining structure 121, and a rotating shaft 114 is provided in the wall of the first slot 1121. When the connecting portion 131 is a clamp provided at the connection, the clamp extends into the first slot 1121 and fits over the rotating shaft 114, thereby achieving a rotational connection between the locking member 130 and the positioning core 110. This connection method is simple and reliable.

[0105] Further, if Figure 10 As shown, the wall of the second movable groove 113 may also be provided with a second slot 1131. The rotating shaft 114 is disposed between the first slot 1121 and the second slot 1131. After a portion of the clamp extends into the first slot 1121 and another portion of the clamp extends into the second slot 1131, both portions can be sleeved onto the rotating shaft 114, thereby increasing the reliability of the rotational connection between the locking member 130 and the positioning core 110.
