Description

Technical Field

[0001] The present invention relates to the technical field of mutual inductors, and in particular to a mutual inductor with an anti-electricity theft function. Background Art

[0002] A mutual inductor is a power transformer used to transfer current or voltage from one circuit to another while changing its value. It is an important component of the power system and can realize the transmission, measurement and protection of electric energy. Mutual inductors are widely used in the power industry and industrial fields and play a key role. Due to the importance of mutual inductors in the power system, they have also become the target of power theft by criminals. Power theft will not only cause economic losses to power companies, but may also pose a threat to the safe operation of the power system. Therefore, the anti-power theft function of the mutual inductor becomes crucial.

[0003] Existing transformers are generally fixed by small screws, and criminals can use tools to dismantle the transformer to steal electricity. At the same time, the protective casing of the transformer is generally fixed directly by screws. During daily inspection and maintenance of the transformer, the protective casing needs to be removed. When removing the protective casing, a screwdriver needs to be used to rotate the fixing screws multiple times, which is a cumbersome operation. At the same time, the protective casing fixed by screws is still difficult to protect the transformer. Therefore, the present application provides a transformer with anti-electricity theft function to meet the needs. Summary of the invention

At the same time, through the connection and cooperation between the fixing hole and the positioning hole, the maintenance personnel can subsequently inspect and replace the lock body shell as a whole, and at the same time, the fixing hole and the positioning hole are hidden inside the protective shell, thereby further preventing criminals from directly disassembling the fixing hole and causing damage to the lock body shell as a whole.

[0018] By setting up an unlocking component, multiple groups of sockets arranged in an array on the top of the unlocking plug disk are used to interfere with criminals, thereby increasing the error rate when criminals insert tools into the correct sockets, and improving the safety redundancy of the unlocking plug disk when facing cracking by criminals. At the same time, by utilizing the elastic cooperation between the elastic telescopic rod and the trigger plate, and utilizing the force applied when criminals insert tools into the wrong sockets, the trigger plate triggers the signal transceiver to send an electrical signal warning. At the same time, through the cooperation between the safety hole at the center of the top of the trigger plate and the insertion column, the locking state of the switching component is switched through the insertion column. The structure is simple and the cost of use is low.

[0019] By setting a switching component, the linkage of the rotation state between the rotating rod and the first lock core is realized. At the same time, the locking and unlocking of the rotation state of the rotating rod is realized through the cooperation between the elastic telescopic rod 2, the chuck and the rotating rod 1, so as to prevent criminals from directly driving the rotating rod to rotate by rotating the first lock core, thereby realizing one-way locking of the top of the rotating rod. At the same time, by utilizing the rotation cooperation of the remaining two groups of rotating rods 1, through the sliding effect of the short sliding rod and the long sliding rod, the locking of the middle and bottom of the rotating rod is realized through the clamping ring and the limit column 3 respectively, thereby realizing triple locking of the rotation state of the rotating rod, preventing criminals from directly destroying the first lock core and then directly opening the protective shell by rotating the rotating rod, further improving the safety redundancy of the switching component, and cooperating with the opening and closing component, the two groups of protective shells are brought close to each other, thereby realizing the protection effect of the mutual inductor. At the same time, the operator can rotate the first lock core by the starting key, and at the same time, cooperate with the switching effect of the switching component, and realize the opening and closing of the two groups of protective shells by driving the rotating rod to rotate by the first lock core. The mechanism is simple, and it is convenient for the later operator to open the two groups of protective shells for the inspection and maintenance of the mutual inductor.

[0043] like Figures 1 to 14As shown, an embodiment of the present invention provides a mutual inductor with an anti-electricity theft function, comprising a mounting base 1, a mutual inductor 2 is mounted on the top of the mounting base 1, a mounting bracket 3 is mounted on one side of the top of the mounting base 1, a support plate 4 is mounted on one side of the mounting bracket 3, the number of the support plates 4 is set to multiple groups, the multiple groups of support plates 4 are arranged at equal angles on one side of the mounting bracket 3, a signal transceiver device 40 is mounted on the bottom of the support plate 4, and a positioning hole 5 is mounted on one side of the top of the mounting bracket 3; a locking component 6, a locking component 6 is mounted on the top of the support plate 4, and the locking component 6 is used to start the operation of the switching component 8; Unlocking component 7, an unlocking component 7 is installed on the top of the support plate 4, and the unlocking component 7 is used to unlock the operating state of the switching component 8; the switching component 8, a switching component 8 is installed on one side of the top of the mounting base 1, and the switching component 8 is used to switch the state of the opening and closing component 9; the opening and closing component 9, an opening and closing component 9 is installed on the top of the mounting base 1, and the opening and closing component 9 is used to realize the outer shell protection of the mutual inductor 2; the unlocking component 7 is located on the side of the locking component 6, the switching component 8 is located at the bottom of the locking component 6, and is located in the same axial direction as the locking component 6, and the opening and closing components 9 are located on both sides of the switching component 8.

[0044] By setting the locking component 6, the top of the first lock core 63 achieves a protective effect, avoiding the first lock core 63 from being directly exposed to the outside, and reducing the possibility of the first lock core 63 being directly damaged by criminals. By setting the unlocking component 7, the error rate of criminals inserting tools into the correct socket 72 is increased, and the safety redundancy of the unlocking disk 71 when facing cracking by criminals is improved. By setting the switching component 8, the triple locking of the rotation state of the rotating rod 81 is achieved, avoiding criminals from directly destroying the first lock core 63 and then directly opening the protective shell 97 by rotating the rotating rod 81, further improving the safety redundancy of the switching component 8, and by setting the opening and closing component 9, the protection effect of the mutual inductor 2 is achieved, and it is convenient for later operators to open the two sets of protective shells 97 to inspect and maintain the mutual inductor 2.

[0045] like Figures 4 to 6As shown, the locking assembly 6 includes a lock body shell 61, a fixing hole 62 is installed on one side of the bottom end of the lock body shell 61, and the lock body shell 61 is connected to the positioning hole 5 at the top of the mounting bracket 3 through the fixing hole 62. The inner wall of the lock body shell 61 is sleeved with a first lock core 63, and a starting key 630 is inserted into the inner wall of the first lock core 63. A rotating block 631 is connected to the bottom end of the first lock core 63, and the surface of the rotating block 631 contacts the inner wall of the rotating chuck 86. A second lock core 64 is sleeved on the inner wall of one side of the lock body shell 61, and a cylinder key 65 is inserted into the inner wall of the second lock core 64. The second lock core 64 is sleeved with a second lock core 64. A meshing plate 66 is installed at one end of the lock core 64, and a bevel gear 67 is meshed on one side of the meshing plate 66. The bevel gear 67 is installed on the inner wall of the lock body shell 61, and one end of the bevel gear 67 is connected to a bevel gear set 68. One group of bevel gears in the bevel gear set 68 is connected to the bevel gear 67 through a transmission rod, and another group of bevel gears in the bevel gear set 68 is installed on the top of the inner wall of the lock body shell 61. One end of the other group of bevel gears in the bevel gear set 68 is connected to a screw 69, which is installed on the top of the inner wall of the lock body shell 61, and an anti-insertion baffle 610 is threadedly sleeved on the outer surface of the screw 69.

[0046] After the operator installs the mutual inductor 2 on the top of the mounting base 1, the operator first inserts the cylinder key 65 into the second lock core 64, and then rotates the cylinder key 65. The cylinder key 65 rotates and drives the toothed disc 66 to rotate synchronously. The toothed disc 66 rotates and engages the bevel gear 67 to rotate. The bevel gear 67 rotates and drives the input end of the bevel gear set 1 68 to rotate synchronously through the transmission rod. The input end of the bevel gear set 1 68 rotates and engages the output end of the bevel gear set 1 68 to rotate synchronously. The output end of the bevel gear set 1 68 rotates and drives the screw 69 to rotate synchronously. When the screw 69 rotates, When the operator needs to replace the second lock core 64, the operator can use a tool to disconnect the positioning hole 5 and the fixing hole 62 at the bottom of the lock body shell 61. The operator can remove the lock body shell 61 to disengage the rotating block 631 from the rotating chuck 86. At this time, the operator can replace the lock body shell 61 as a whole and reconnect and fix the replaced lock body shell 61 through the positioning hole 5 and the fixing hole 62.

[0047] The operator then inserts the starting key 630 into the first lock core 63, and then turns the starting key 630. When the starting key 630 turns, it drives the first lock core 63 to rotate synchronously. When the first lock core 63 rotates, it drives the rotating block 631 at the bottom to rotate synchronously. When the rotating block 631 rotates, it drives the rotating chuck 86 to rotate synchronously. When the rotating chuck 86 rotates, it drives the limiting column 2 85 to rotate synchronously. When the limiting column 2 85 rotates, it drives one of the groups of chucks 84 to rotate synchronously. When this group of chucks 84 rotates, it drives the rotating rod 81 to rotate through the elastic telescopic rod 2 83 at the bottom of this group of chucks 84.

[0048] By setting the linkage cooperation between the cylinder key 65, the toothed plate 66, the bevel gear 67, the bevel gear set 68 and the screw 69, the sliding opening and closing of the anti-insertion plate 610 at the top of the inner wall of the lock body shell 61 is realized, so as to avoid the first lock core 63 being directly exposed to the outside, and to prevent criminals from directly prying open the first lock core 63 with tools and also to prevent criminals from directly damaging the surface of the first lock core 63. At the same time, through the connection cooperation between the fixing hole 62 and the positioning hole 5, the maintenance personnel can subsequently inspect and replace the lock body shell 61 as a whole.

[0049] like Figures 7 to 9 As shown, the unlocking assembly 7 includes an unlocking insert plate 71, the number of the unlocking insert plates 71 is set to multiple groups, and the multiple groups of unlocking insert plates 71 are nested and installed on the top of the support plate 4. The surface of the unlocking insert plate 71 is penetrated by a plug hole 72, and a rubber seal 73 is installed at the top edge of the plug hole 72. The material of the rubber seal 73 is set to nitrile rubber, and the inner wall of the rubber seal 73 contacts an insertion column 74. The top of the insertion column 74 is installed with a direction indicator 75, and the bottom surface of the insertion column 74 is installed with a limit column 76. The bottom surface of the unlocking insert plate 71 A limit ring 77 is installed at the center of the end, and the bottom end of the limit ring 77 contacts the top surface of the limit column 76. An elastic telescopic rod 78 is installed at the bottom edge of the unlocking plug plate 71. The number of the elastic telescopic rods 78 is set to two groups. The two groups of elastic telescopic rods 78 are installed on both sides of the bottom end of the unlocking plug plate 71 in the same axial direction. The bottom end of the elastic telescopic rod 78 is connected to a trigger plate 79. A safety hole 710 is installed through the center of the top of the trigger plate 79. The top side surface of the trigger plate 79 contacts the signal transceiver device 40.

[0050] Then, the operator inserts the insertion column 74 into the correct insertion hole 72 at the top of the unlocking plug disk 71. The insertion column 74 pushes open the rubber seal 73 while inserting the insertion hole 72. The insertion column 74 passes through the safety hole 710 at the center of the trigger plate 79 while inserting, contacts and pushes the surface of the rotating rod 87. When the insertion column 74 is inserted into place, the operator rotates the insertion column 74 according to the indication direction of the direction indicator 75. The rotation of the insertion column 74 drives the limiting column 76 on the bottom surface to rotate, so that the limiting column 76 approaches and contacts the limiting ring 77, so as to achieve the clamping effect between the limiting column 76 and the limiting ring 77, so that the insertion column 74 remains in a pressed state.

[0051] Similarly, when criminals try to insert a tool into the socket 72, when the tool is not inserted into the correct socket 72, the bottom end of the tool inserted by the criminals contacts and pushes the trigger plate 79 to slide downward, and the trigger plate 79 slides while driving the elastic telescopic rod 78 to extend. At the same time, one side of the bottom end of the trigger plate 79 contacts the signal transceiver device 40, causing the signal transceiver device 40 to be triggered and send out an electrical signal alarm, thereby alerting the criminals to the theft of electricity.

[0052] By setting up multiple sets of unlocking disks 71, the security redundancy of the unlocking disks 71 is improved when facing cracking by criminals. The force exerted by criminals when inserting tools into the wrong socket 72 is utilized to trigger the signal transceiver device 40 to send an electrical signal warning through the trigger plate 79. At the same time, through the cooperation between the safety hole 710 at the top center of the trigger plate 79 and the insertion column 74, the locking state of the switching component 8 is switched through the insertion column 74. The structure is simple and the cost of use is low.

[0053] like Figures 10 to 13As shown, the switching assembly 8 includes a rotating rod 81, which is mounted on the top of the mounting base 1, a clamping column 82 is mounted on the middle surface of the rotating rod 81, an elastic telescopic rod 83 is mounted on the top of the rotating rod 81, and the number of the elastic telescopic rods 83 is set to two groups. The other group of elastic telescopic rods 83 in the two groups is mounted on the bottom of the rotating rod 81, and a chuck 84 is mounted on the top of one of the two groups of elastic telescopic rods 83. The number of chucks 84 is set to two groups, and the other group of chucks 84 in the two groups is mounted on the top of the mounting base 1. The inner wall of the chuck 84 contacts the limiting column 85, and the limiting column 85 is mounted on the inner wall of the mounting bracket 3. A rotating chuck 86 is mounted on the top of the limiting column 85, and the inner wall of the rotating chuck 86 contacts the surface of the rotating block 631. The switching assembly 8 also includes a rotating rod 87, and the rotating rod 87 is 8 The number of 7 is set to three groups, three groups of rotating rods 87 are installed at the bottom end of the support plate 4, one end surfaces of the three groups of rotating rods 87 are all in contact with the insertion column 74, the other end of one of the three groups of rotating rods 87 is in contact with one of the two groups of chucks 84, the other ends of the remaining two groups of rotating rods 87 in the three groups of rotating rods 87 are connected with connecting rods 88, the bottom ends of the two groups of connecting rods 88 are respectively connected with short sliding rods 89 and long sliding rods 810, a snap ring 811 is installed on one side of the bottom end of the short sliding rod 89, the inner wall of the snap ring 811 is in contact with the surface of the clamping column 82, a mounting plate 812 is installed on one side of the bottom end of the long sliding rod 810, the top of the mounting plate 812 is connected to the bottom end of another group of elastic telescopic rods 2 83, a limiting column three 813 is installed on the bottom end of the mounting plate 812, and the surface of the limiting column three 813 is in contact with the inner wall of another group of chucks 84.

[0054] When the insertion column 74 is pressed down, it contacts and pushes one end of the rotating rod 1 87. Under the insertion action of the insertion column 74, multiple groups of rotating rods 1 87 are rotated. When one group of rotating rods 1 87 rotates, the other end contacts and pushes one group of chucks 84 to slide upward. When this group of chucks 84 slides, it drives one group of elastic telescopic rods 2 83 to extend, so that the inner wall of the chuck 84 contacts the limiting column 2 85, so that a clamping state is formed between the chuck 84 and the limiting column 2 85.

[0055] At the same time, the other two groups of rotating rods 87 rotate while the other ends pull the two groups of connecting rods 88 respectively. Under the connection action of the two groups of connecting rods 88, the short sliding rod 89 and the long sliding rod 810 slide upward synchronously. The sliding of the short sliding rod 89 drives the retaining ring 811 to slide synchronously. The retaining ring 811 slides and loses contact with the surface of the clamping column 82. Similarly, the sliding of the long sliding rod 810 drives the mounting plate 812 at the bottom to slide synchronously. The sliding of the mounting plate 812 drives another group of elastic telescopic rods 2 83 to contract. At the same time, the mounting plate 812 drives the limiting column 3 813 at the bottom to slide synchronously, so that the limiting column 3 813 loses contact with the inner wall of the other group of chucks 84.

[0056] When the tool inserted by the criminals is not inserted into the correct socket 72, the tool inserted by the criminals cannot push one end of the rotating rod 87, so that one group of chucks 84 and the rotating block 631 cannot form a clamping state. Similarly, the clamping column 82 and the clamping ring 811 remain in a clamping state, and the limit column three 813 and the other group of chucks 84 also remain in a clamping state.

[0057] By setting the rotational cooperation between the rotating chuck 86 and the rotating block 631, the rotational state linkage between the rotating rod 81 and the first lock core 63 is realized. At the same time, through the cooperation between the elastic telescopic rod 2 83, the chuck 84 and the rotating rod 1 87, the rotational state of the rotating rod 81 is locked and unlocked. At the same time, the rotational state of the rotating rod 81 is triple locked by the retaining ring 811 and the limiting column 3 813 respectively, so as to prevent criminals from directly opening the protective shell 97 by rotating the rotating rod 81.

[0058] like Fig.14 As shown, the opening and closing component 9 includes a bevel gear set 91, one of the bevel gears in the bevel gear set 91 is sleeved on the surface of the rotating rod 81, and the other bevel gear in the bevel gear set 91 is installed on one side of the inner wall of the mounting bracket 3. The number of bevel gear sets 91 is set to multiple groups, and the multiple bevel gear sets 91 are equidistantly arranged on the surface of the rotating rod 81. The extended part of the other bevel gear in the bevel gear set 91 is sleeved on the surface of a rotating rod 92, and both ends of the rotating rod 92 are connected to a connecting rod 93, and the other end of the connecting rod 93 is connected to a sliding rod 94, and a hook claw 95 is installed at one end of the sliding rod 94, and one side of the inner wall of the hook claw 95 is in contact with a slot 96, and a protective shell 97 is installed at one end of the slot 96, and the bottom end of the protective shell 97 is in contact with the mounting base 1.

[0059] When the rotating rod 81 rotates, the input end of the bevel gear set 91 is driven to rotate synchronously. When the input end of the bevel gear set 91 rotates, the output end of the meshing bevel gear set 91 is driven to rotate synchronously. When the output end of the bevel gear set 91 rotates, the rotating rod 92 is driven to rotate synchronously. When the rotating rod 92 rotates, the connecting rod 93 is pulled, so that the two groups of connecting rods 93 are close to each other. When the connecting rod 93 slides, the sliding rod 94 is pulled, and the hook 95 is pulled by the sliding rod 94. Under the sliding action of the hook 95, the two groups of protective shells 97 are brought close to each other and closed, thereby achieving the protection effect of the mutual inductor 2.

[0060] When criminals try to directly reversely rotate the first lock core 63, since the rotating block 631 remains disengaged from one of the groups of chucks 84, the first lock core 63 cannot directly drive the rotating rod 81 to rotate, and the criminals cannot move the two groups of protective shells 97 away from each other and open. At the same time, with the clamping column 82 and the clamping ring 811 remaining in a clamping state, and the limiting column three 813 remaining in a clamping state with the other group of chucks 84, when criminals try to directly rotate the rotating rod 81, they still cannot move the two groups of protective shells 97 away from each other and open, thereby achieving the anti-theft effect on the mutual inductor 2.

[0061] By setting the linkage between bevel gear set 2 91, rotating rod 2 92, connecting rod 2 93 and sliding rod 94, the two sets of protective shells 97 can be brought close to each other, thereby realizing the protection effect of the mutual inductor 2. At the same time, the operator can rotate the first lock core 63 by starting the key 630, and at the same time cooperate with the switching effect of the switching component 8 to drive the rotating rod 81 to rotate through the first lock core 63 to realize the opening and closing of the two sets of protective shells 97. The mechanism is simple and it is convenient for the later operator to open the two sets of protective shells 97 for the inspection and maintenance of the mutual inductor 2.

[0062] The working principle of the technical solution provided by the present invention is as follows:

[0063] After the operator installs the mutual inductor 2 on the top of the mounting base 1, the operator first inserts the cylinder key 65 into the second lock core 64, and then rotates the cylinder key 65. The cylinder key 65 rotates and drives the toothed disc 66 to rotate synchronously. The toothed disc 66 rotates and engages the bevel gear 67 to rotate. The bevel gear 67 rotates and drives the input end of the bevel gear set 1 68 to rotate synchronously through the transmission rod. The input end of the bevel gear set 1 68 rotates and engages the output end of the bevel gear set 1 68 to rotate synchronously. The output end of the bevel gear set 1 68 rotates and drives the screw 69 to rotate synchronously. When the screw 69 rotates, When the second lock core 63 is replaced, the operator can use a tool to disconnect the positioning hole 5 and the fixing hole 62 at the bottom of the lock body shell 61. The operator can remove the lock body shell 61 to disengage the rotating block 631 from the rotating chuck 86. At this time, the operator can replace the lock body shell 61 as a whole and reconnect and fix the replaced lock body shell 61 through the positioning hole 5 and the fixing hole 62.

[0064] Then, the operator inserts the insertion column 74 into the correct socket 72 at the top of the unlocking plug disk 71. The insertion column 74 pushes open the rubber seal 73 while being inserted into the socket 72. The insertion column 74 passes through the safety hole 710 at the center of the trigger plate 79 while being inserted, contacts and pushes the surface of the rotating rod 87. When the insertion column 74 is inserted into place, the operator rotates the insertion column 74 according to the indication direction of the direction indicator 75. The rotation of the insertion column 74 drives the limit column 76 on the bottom surface to rotate, so that the limit column 76 approaches and contacts the limit ring 77, thereby realizing the clamping effect between the limit column 76 and the limit ring 77, so that the insertion column 74 remains in a pressed down state.

[0065] When the insertion column 74 is pressed down, it contacts and pushes one end of the rotating rod 1 87. Under the insertion action of the insertion column 74, multiple groups of rotating rods 1 87 are rotated. When one group of rotating rods 1 87 rotates, the other end contacts and pushes one group of chucks 84 to slide upward. When this group of chucks 84 slides, it drives one group of elastic telescopic rods 2 83 to extend, so that the inner wall of the chuck 84 contacts the limiting column 2 85, so that a clamping state is formed between the chuck 84 and the limiting column 2 85.

[0066] At the same time, the other two groups of rotating rods 87 rotate while the other ends pull the two groups of connecting rods 88 respectively. Under the connection action of the two groups of connecting rods 88, the short sliding rod 89 and the long sliding rod 810 slide upward synchronously. The sliding of the short sliding rod 89 drives the retaining ring 811 to slide synchronously. The retaining ring 811 slides and loses contact with the surface of the clamping column 82. Similarly, the sliding of the long sliding rod 810 drives the mounting plate 812 at the bottom to slide synchronously. The sliding of the mounting plate 812 drives another group of elastic telescopic rods 2 83 to contract. At the same time, the mounting plate 812 drives the limiting column 3 813 at the bottom to slide synchronously, so that the limiting column 3 813 loses contact with the inner wall of the other group of chucks 84.

[0067] The operator then inserts the starting key 630 into the first lock core 63, and then turns the starting key 630. When the starting key 630 turns, it drives the first lock core 63 to rotate synchronously. When the first lock core 63 rotates, it drives the rotating block 631 at the bottom to rotate synchronously. When the rotating block 631 rotates, it drives the rotating chuck 86 to rotate synchronously. When the rotating chuck 86 rotates, it drives the limiting column 2 85 to rotate synchronously. When the limiting column 2 85 rotates, it drives one of the groups of chucks 84 to rotate synchronously. When this group of chucks 84 rotates, it drives the rotating rod 81 to rotate through the elastic telescopic rod 2 83 at the bottom of this group of chucks 84.

[0068] When the rotating rod 81 rotates, the input end of the bevel gear set 91 is driven to rotate synchronously. When the input end of the bevel gear set 91 rotates, the output end of the meshing bevel gear set 91 is driven to rotate synchronously. When the output end of the bevel gear set 91 rotates, the rotating rod 92 is driven to rotate synchronously. When the rotating rod 92 rotates, the connecting rod 93 is pulled, so that the two groups of connecting rods 93 are close to each other. When the connecting rod 93 slides, the sliding rod 94 is pulled, and the hook 95 is pulled by the sliding rod 94. Under the sliding action of the hook 95, the two groups of protective shells 97 are brought close to each other and closed, thereby achieving the protection effect of the mutual inductor 2.

[0069] Similarly, when criminals try to insert a tool into the socket 72, when the tool is not inserted into the correct socket 72, the bottom end of the tool inserted by the criminals contacts and pushes the trigger plate 79 to slide downward, and the trigger plate 79 slides while driving the elastic telescopic rod 78 to extend. At the same time, one side of the bottom end of the trigger plate 79 contacts the signal transceiver device 40, causing the signal transceiver device 40 to be triggered and send out an electrical signal alarm, thereby alerting the criminals to the theft of electricity.

[0070] When the tool inserted by the criminals is not inserted into the correct socket 72, the tool inserted by the criminals cannot push one end of the rotating rod 1 87, so that one group of chucks 84 and the limiting column 2 85 cannot form a clamping state. Similarly, the clamping column 82 and the retaining ring 811 remain in a clamping state, and the limiting column 3 813 and the other group of chucks 84 also remain in a clamping state.

[0071] When criminals try to directly reversely rotate the first lock core 63, since the rotating block 631 remains disengaged from one of the groups of chucks 84, the first lock core 63 cannot directly drive the rotating rod 81 to rotate, and the criminals cannot move the two groups of protective shells 97 away from each other and open. At the same time, with the clamping column 82 and the clamping ring 811 remaining in a clamping state, and the limiting column three 813 remaining in a clamping state with the other group of chucks 84, when criminals try to directly rotate the rotating rod 81, they still cannot move the two groups of protective shells 97 away from each other and open, thereby achieving the anti-theft effect on the mutual inductor 2.
