Description

Technical Field

[0001] This invention belongs to the field of metering box technology, specifically relating to an adjustable energy metering box. Background Technology

[0002] An electricity metering box is a core device in a power system used to measure electrical energy. It is a collection of metering instruments and auxiliary equipment necessary for measuring electrical energy. Simply put, it converts electrical energy into electrical signals through its own electricity meter and displays them on external dials such as ammeters and voltmeters, so that users or staff can know various electrical energy indicators.

[0003] Patent publication number CN118174149B discloses an adjustable energy metering box, belonging to the technical field of energy metering boxes. The box has an inlet and an outlet hole running from left to right at the bottom of its casing. A gap fine-tuning mechanism is installed on the bottom inner wall of the casing. This mechanism includes two guide rings installed on the bottom inner wall of the casing, each with multiple guide grooves running through its top. A guide rod is installed on one side of the inner wall of each guide groove. This patent utilizes the gap fine-tuning mechanism to make two guide gears rotate synchronously. When the displacement grooves rotate, the connecting slide pin slides laterally, and the connecting slider slides along the inner wall of the guide grooves within the guide rings. The distance between the multiple opening adjustment blocks increases, automatically and precisely adjusting to the specified opening size according to different cable diameters, fitting the inlet and outlet cables. This eliminates the need to seal large gaps, making the wiring and use of the energy metering box more time-saving and labor-saving.

[0004] However, this device also has shortcomings: it relies on the adjustment block to automatically fit the line, thus saving wiring time. However, this device keeps the limiting end face of the wire in a tightly closed state. The metering box easily generates heat on the wire during operation. At this time, the heat at the limiting point of the wire is difficult to dissipate quickly, which can easily lead to softening and damage of its outer insulation layer, thereby increasing the possibility of exposed wire core. At the same time, it is difficult to test the connection strength of the installed wires. If the connection is not good, it is easy to increase the probability of the wires falling off when pulled. And before the line is connected, it is difficult to automatically complete the straightening work of wires of different diameters, which can easily reduce the regularity of the overall layout of the line when multiple circuits are connected. Summary of the Invention

[0005] The purpose of this invention is to provide an adjustable power metering box to solve the problem mentioned in the background art of difficulty in testing the connection strength of installed wires, which can easily lead to the wires falling off when pulled due to poor connection.

[0006] To achieve the above objectives, the present invention provides an adjustable electricity metering box, comprising: a box body, wherein two metering mechanisms are symmetrically arranged on the back of the inner wall of the box body; a wire to be connected to the bottom of the metering mechanism is passed through a square groove at the bottom of the box body and then connected to the bottom of the metering mechanism after passing through a base; an electric rotating rod is rotatably mounted on the bottom of the inner wall of the box body, and a gear is fixedly mounted through the outer wall of the bottom end of the electric rotating rod; two bases are symmetrically and fixedly mounted on the bottom of the inner wall of the box body, and a transmission gear ring is rotatably mounted on the top of the base; an anti-glare device is provided above the transmission gear ring to refract external light sources to illuminate the interior of the box body; a straightening device is provided around the anti-glare device to prevent the wire connection ends from bending; and a vertical rod is fixedly mounted on the top edge of the base, with the outer wall of the vertical rod being rotatable. A toothed plate is installed, and a sliding block is slidably installed inside the base groove. A closing plate is fixedly installed through the outer wall of the sliding block. Before connection, the electric rotating rod is started. When the electric rotating rod rotates along the bottom of the inner wall of the box, it drives the gear to rotate. When the gear rotates, it drives the meshing transmission gear ring to revolve along the top of the base. The transmission gear ring drives the toothed plate that meshes with itself and is limited by the vertical rod to start revolve. When the toothed plate rotates, it drives the closing plate that meshes with itself to generate a horizontal force. The closing plate causes the sliding block to start sliding horizontally along the top groove of the base. At this time, the circumferentially distributed closing plates move closer to each other, thereby sealing the hollow part of the base. A pressure frame is movably installed through the outer wall of the spiral groove of the electric rotating rod. The bottom of the back end of the pressure frame is hinged to the transmission frame by a torsion spring. A telescopic baffle is fixedly installed on the back of the inner wall of the box.

[0007] In one possible implementation, light-transmitting slots are provided at both the left and right ends of the housing, and a square slot is provided at the bottom of the housing. The metering mechanism displays the electrical energy. The electric rotating rod is driven by a servo motor. A non-self-locking spiral groove is provided on the outer wall of the top of the electric rotating rod. Several sliding grooves are provided on the top of the base in a circular pattern, and the bottom of the base is hollowed out. A tooth groove is provided on the outer wall of the transmission gear ring near the gear, and the tooth groove on the outer wall of the transmission gear ring meshes with the gear.

[0008] In one possible implementation, the toothed plate meshes internally with the transmission toothed ring, and the closing plate has a toothed groove at one end near the vertical rod. The toothed groove of the closing plate meshes with the toothed plate. The bottom of the transmission frame is hinged to the top of the telescopic end of the telescopic baffle. When the closing plate contacts the outer wall of the wire, it stops closing. At this time, there is a certain gap between the closing plate and the hollow part of the base. When the electric rotating rod rotates, it guides the internal locking block of the pressure frame through the non-self-locking spiral groove on its outer wall, driving the pressure frame to slide down along the back of the inner wall of the box. The pressure frame drives the transmission frame to move synchronously. The transmission frame is limited by the telescopic end of the telescopic baffle. At this time, the hinge shaft of the transmission frame begins to rotate, and the transmission frame moves in an arc trajectory and pushes the telescopic end of the telescopic baffle to begin to move along the arc. The telescopic baffle blocks the non-wire connection port at the bottom of the metering mechanism.

[0009] In one possible implementation, the anti-glare device includes a contact frame, the sidewall of which is fixedly installed on the outer wall of the transmission gear ring. A T-shaped frame is slidably installed on the inner sidewall of the housing, and an arc panel is fixedly installed at the bottom of the T-shaped frame. When the transmission gear ring revolves, it drives the contact frame to move synchronously, and the contact frame releases its contact with the bottom of the arc panel. At this time, the T-shaped frame and the arc panel slide downward along the inner sidewall of the housing due to their own weight. A limit plate is fixedly installed at the top edge of the T-shaped frame, and a crossbar is fixedly installed inside the light-transmitting groove of the housing. A light-reflecting plate is rotatably installed on the outer wall of the crossbar through a torsion spring.

[0010] In one possible implementation, the bottom of the arc panel contacts the top of the abutment frame, the inclined surface of the refracting plate contacts the top of the limiting plate, the T-shaped frame drives the limiting plate to move synchronously, and when the limiting plate descends, it no longer limits the refracting plate. The top of the refracting plate begins to flip along the outer wall of the crossbar in an arc trajectory towards the inside of the box through the torsion spring. At this time, the refracting plate refracts the external light source to the bottom of the measuring mechanism to form an illumination source.

[0011] In one possible implementation, two elastic telescopic rods are symmetrically and fixedly installed on the outer wall of the T-shaped frame away from the contact frame. The telescopic ends of the elastic telescopic rods extend through the interior of the T-shaped frame. T-shaped plates are fixedly installed on one side of each other, with the tops of the two T-shaped plates being of different heights. The bottom of the T-shaped plates has a mounting groove. When the wire rises, it passes through and contacts the two cleaning rollers. The external contact of the wire causes the cleaning rollers to generate a horizontal force, which in turn causes the T-shaped plates to move towards the edge of the T-shaped frame. The cleaning rollers are rotatably installed inside the mounting grooves of the T-shaped plates. The T-shaped plates cause the elastic telescopic rods, which are limited by the T-shaped frame, to retract. Thus, the cleaning rollers remain in close contact with the surface of the wire under the action of the spring. Then, when the T-shaped frame suddenly drops, the cleaning rollers move synchronously, at which time the cleaning rollers apply a downward force to the wire connected to the bottom of the metering mechanism.

[0012] In one possible implementation, the straightening device includes a through rod that penetrates the outer wall and is fixedly installed inside the top of a T-shaped plate. Fixed plates are fixedly installed at both ends of the through rod. When the wire is threaded, it passes between several symmetrically distributed squeezing rollers at different heights. Simultaneously, the squeezing rollers are limited by the fixed plates, which in turn are limited by the through rod. The through rod is limited by the T-shaped plate. Squeezing rollers are rotatably mounted between the fixed plates, which are close to each other on one side. The squeezing rollers straighten the wire through their vertical position difference. Therefore, when the cleaning rollers are adjusted, the through rod adjusts the spacing of the squeezing rollers via the T-shaped plate. Since the circumferential surfaces of the squeezing rollers and the cleaning rollers are on the same horizontal plane, the external friction of the wire against the squeezing rollers generates friction. At this time, the squeezing rollers with height differences rotate and straighten the twisted parts of the wire. Afterward, when the through rod moves downward, it causes the squeezing rollers to move synchronously, providing more operating space for manual connection by the operator.

[0013] In one possible implementation, a reciprocating screw is installed through and fixedly mounted on the side wall of the extrusion roller. The outer wall of the reciprocating screw has a non-self-locking reciprocating helical groove. A push plate is installed through and movably mounted on the outer wall of the reciprocating screw. A limit rod is fixedly mounted on the middle side wall of the push plate. The outer wall of the limit rod is installed through and slidably mounted inside the T-shaped plate. An L-shaped slotted plate is installed through and fixedly mounted on the outer wall of the limit rod. When the extrusion roller rotates, it drives the reciprocating screw to rotate. The reciprocating screw guides the built-in locking block of the push plate through its own non-self-locking reciprocating helical groove. The push plate drives the limit rod to reciprocate horizontally along the inside of the T-shaped plate.

[0014] In one possible implementation, the limiting rod limits the horizontal relationship between the extrusion roller and the T-shaped plate. The outer wall of the vertical end of the T-shaped plate is located on the internal movement trajectory of the L-shaped slotted plate. The L-shaped slotted plate detects whether there is lateral separation between the T-shaped plate and the telescopic end of the elastic telescopic rod. At this time, the limiting rod limits the extrusion roller and drives the L-shaped slotted plate to move outward from the T-shaped plate. At this time, the operator can observe whether the interior of the L-shaped slotted plate can smoothly penetrate the outer wall of the T-shaped plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: through the cooperation of an electric rotating rod, gear, base, transmission gear ring, vertical rod, toothed plate, sliding block, closing plate, pressure frame, transmission frame and telescopic baffle, the layout and positioning adjustment of wires of different diameters are automatically and efficiently completed through gear drive, and the opening is sealed. At the same time, a small gap is left to facilitate heat dissipation of the wire end face limited by the closing plate, preventing the insulation sheath at the wire limiting point from softening and breaking due to long-term heat exposure, and preventing the wire core from being exposed and leaking electricity. Through the blocking and limiting of the telescopic baffle, the number of end holes is increased due to the cooperation of multiple meters, which would increase the test time required for wiring. This allows the installer to quickly identify the connection port when wiring, improving the accuracy of wiring.

[0016] By incorporating an anti-glare device, a static lighting source refracted by the light from the transmission gear ring, contact frame, T-frame, arc panel, limit plate, crossbar, refracting plate, elastic telescopic rod, and cleaning roller facilitates the inspection and troubleshooting of connected circuits by staff. This eliminates the need for handheld or head-mounted lighting equipment, preventing eye discomfort caused by reflections from the internal metal surfaces of the enclosure due to frequent movements. The cleaning roller forcefully pulls the wire downwards to test the connection strength between the wire and the measuring mechanism. If a detachment occurs, staff can promptly detect and maintain the connection, preventing interruptions in electrical signal measurement due to external force.

[0017] By employing a straightening device—combining a T-shaped plate, a through-bar, a fixed plate, a pressing roller, a reciprocating screw, a push plate, a limit rod, and an L-shaped slotted plate—the rotation and straightening of the pressing roller eliminates the need for manual adjustment of bent sections of the wire. The internal mechanical structure enhances the straightness of the wire, ensuring the overall neatness of the completed wiring layout. This facilitates quick wiring repairs during subsequent fault detection and prevents bending from complicating the removal of the external insulation layer at the wire connection points. The through-bar ensures the pressing roller remains horizontal to the vertical plane of the T-shaped plate, preventing unidirectional tilting during prolonged use and reducing the straightening effect on the wire. Furthermore, the movement of the L-shaped slotted plate provides a reference standard for determining the horizontal orientation of the pressing roller, improving judgment accuracy.

[0020] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0021] like Figures 1-8 As shown, one embodiment of the present invention is: an adjustable energy metering box, comprising: a box body 1, two metering mechanisms 2 symmetrically arranged on the back of the inner wall of the box body 1, an electric rotating rod 3 rotatably installed on the bottom of the inner wall of the box body 1, a gear 4 through and fixedly installed on the outer wall of the bottom end of the electric rotating rod 3, two bases 5 symmetrically and fixedly installed on the bottom of the inner wall of the box body 1, a transmission gear ring 6 rotatably installed on the top of the base 5, an anti-glare device 14 for refracting external light sources to illuminate the inside of the box body 1 is provided above the transmission gear ring 6, a straightening device 15 for preventing the bending of the wiring connection end is provided around the anti-glare device 14, a vertical rod 7 is fixedly installed at the top edge of the base 5, a toothed plate 8 through and rotatably installed on the outer wall of the vertical rod 7, a sliding block 9 is slidably installed inside the sliding groove of the base 5, a closing plate 10 through and fixedly installed on the outer wall of the sliding block 9, a pressure frame 11 through and movably installed on the outer wall of the spiral groove of the electric rotating rod 3, a transmission frame 12 is hinged to the bottom of the back end of the pressure frame 11 by a torsion spring, and a telescopic baffle 13 is fixedly installed on the back of the inner wall of the box body 1.

[0022] Both ends of the housing 1 have light-transmitting slots, and the bottom of the housing 1 has a square slot. The metering mechanism 2 displays the electrical energy. The electric rotating rod 3 is driven by a servo motor. The top outer wall of the electric rotating rod 3 has a non-self-locking spiral groove. The top of the base 5 has several sliding grooves in a circular pattern, and the bottom of the base 5 has a hollow design. The outer wall of the transmission gear ring 6 near the gear 4 has a tooth groove, and the tooth groove on the outer wall of the transmission gear ring 6 meshes with the gear 4.

[0023] The toothed plate 8 meshes internally with the transmission toothed ring 6. The closing plate 10 has a toothed groove at one end near the vertical rod 7. The toothed groove of the closing plate 10 meshes with the toothed plate 8. The bottom of the transmission frame 12 is hinged to the top of the telescopic end of the telescopic baffle 13.

[0024] Driven by gear 4, the layout and positioning of wires of different diameters are automatically and efficiently adjusted, and the openings are sealed. At the same time, a small gap is left to allow heat dissipation for the wire end face limited by the closing plate 10, preventing the insulation at the wire limiting point from softening and breaking due to prolonged heat, and preventing the wire core from being exposed and leaking electricity. Through the blocking and limiting of the telescopic baffle 13, the number of end holes is increased due to the cooperation of multiple meters, which would increase the test time required for wiring. This allows the installer to quickly identify the connection port when wiring, improving the accuracy of wiring.

[0025] In use, the wire that needs to be connected to the bottom of the measuring mechanism 2 is passed through the square slot at the bottom of the housing 1 and then into the bottom of the measuring mechanism 2 after passing through the base 5. Before connection, the electric rotating rod 3 is started. When the electric rotating rod 3 rotates along the bottom of the inner wall of the housing 1, it drives the gear 4 to rotate. When the gear 4 rotates, it drives the meshing transmission gear ring 6 to revolve along the top of the base 5. The transmission gear ring 6 drives the toothed plate 8, which meshes with itself and is limited by the vertical rod 7, to start revolve. When the toothed plate 8 rotates, it drives the closing plate 10, which meshes with itself, to generate a horizontal force. The closing plate 10 causes the sliding block 9 to start sliding horizontally along the sliding groove at the top of the base 5. At this time, the closing plates 10, which are distributed in a circle, are in phase. The two sides move closer together to seal the hollow part of the base 5. When the closing plate 10 contacts the outer wall of the wire, it stops closing. At this time, there is a certain gap between the closing plate 10 and the hollow part of the base 5. When the electric rotating rod 3 rotates, it guides the built-in block of the pressure frame 11 through the non-self-locking spiral groove on its outer wall, driving the pressure frame 11 to slide down along the back of the inner wall of the box 1. The pressure frame 11 drives the transmission frame 12 to move synchronously. The transmission frame 12 is limited by the telescopic end of the telescopic baffle 13. At this time, the hinge shaft of the transmission frame 12 begins to rotate. The transmission frame 12 moves in an arc trajectory and pushes the telescopic end of the telescopic baffle 13 to start along the arc. The telescopic baffle 13 blocks the non-wire connection port at the bottom of the measuring mechanism 2.

[0026] According to the above embodiments, driven by gear 4, the layout and positioning adjustment of wires of different diameters are automatically and efficiently completed, and the openings are sealed. At the same time, a small gap is left to facilitate heat dissipation of the wire end face limited by the closing plate 10, preventing the insulation sheath at the wire limiting point from softening and breaking due to long-term heat exposure, and preventing the wire core from being exposed and leaking electricity. Through the blocking and limiting of the telescopic baffle 13, the number of end holes is increased due to the cooperation of multiple meters, which would increase the test time required for wiring. This allows the installer to quickly determine the connection port when wiring, improving the accuracy of wiring.

[0027] like Figures 1-8 As shown, based on the above embodiments, another embodiment of the present invention further includes an anti-glare device 14; In one possible implementation, the anti-glare device 14 includes a contact frame 141, the sidewall of which is fixedly installed on the outer wall of the transmission gear ring 6. A T-shaped frame 142 is slidably installed on the inner sidewall of the housing 1. An arc panel 143 is fixedly installed at the bottom of the T-shaped frame 142. A limit plate 144 is fixedly installed at the top edge of the T-shaped frame 142. A crossbar 145 is fixedly installed inside the light-transmitting groove of the housing 1. A light-reflecting plate 146 is rotatably installed on the outer wall of the crossbar 145 through a torsion spring.

[0028] The bottom of the curved panel 143 contacts the top of the abutment frame 141, and the inclined surface of the refracting plate 146 contacts the top of the limiting plate 144.

[0029] Two elastic telescopic rods 147 are symmetrically and fixedly installed on the outer wall of the T-shaped frame 142 away from the contact frame 141. The telescopic ends of the elastic telescopic rods 147 extend through the interior of the T-shaped frame 142. T-shaped plates 148 are fixedly installed on one side of the telescopic ends of the two elastic telescopic rods 147, which are close to each other. The top heights of the two T-shaped plates 148 are different, and the bottom of the T-shaped plates 148 is provided with an installation groove. A cleaning roller 149 is rotatably installed inside the installation groove of the T-shaped plate 148.

[0030] The static lighting source refracted by the light-refracting plate 146 facilitates the inspection and troubleshooting of the connected circuits by the staff. The staff does not need to use handheld or head-mounted lighting equipment for observation, avoiding eye discomfort caused by the light emitted by the lighting equipment being reflected by the metal surface inside the housing 1 due to the staff's frequent movements. The connection strength between the wire and the measuring mechanism 2 is tested by pulling the wire downward sharply by the cleaning roller 149. If a detachment occurs, the staff can be notified in time for maintenance, avoiding the interruption of the electrical signal measuring work due to detachment caused by external force in subsequent use.

[0031] In use, when the transmission gear ring 6 revolves, it drives the contact frame 141 to move synchronously. The contact frame 141 releases its contact with the bottom of the arc panel 143. At this time, the T-shaped frame 142 and the arc panel 143 slide downward along the inner side wall of the housing 1 due to their own weight. The T-shaped frame 142 drives the limiting plate 144 to move synchronously. When the limiting plate 144 descends, it no longer limits the refracting plate 146. The top of the refracting plate 146 begins to flip inward along the outer wall of the crossbar 145 in an arc trajectory through the torsion spring. At this time, the refracting plate 146 refracts the external light source to the bottom of the measuring mechanism 2 to form illumination light. Source; When the wire rises, it passes through and contacts the two cleaning rollers 149. The external force of the wire, through contact, causes the cleaning rollers 149 to generate a horizontal force. The cleaning rollers 149 cause the T-shaped plate 148 to move towards the edge of the T-shaped frame 142. The T-shaped plate 148 causes the elastic telescopic rod 147, which is limited by the T-shaped frame 142, to begin to retract. Thus, the cleaning rollers 149 are always in close contact with the surface of the wire under the action of the spring. Then, the cleaning rollers 149 move synchronously when the T-shaped frame 142 suddenly drops. At this time, the cleaning rollers 149 apply a downward force to the wire connected to the bottom of the metering mechanism 2.

[0032] According to the above embodiment, the static lighting source refracted by the light-refracting plate 146 facilitates the inspection and troubleshooting of the connected circuits by the staff. Moreover, the staff does not need to use handheld or head-mounted lighting equipment for observation, avoiding eye discomfort caused by the light source emitted by the lighting equipment being reflected by the metal surface inside the housing 1 due to the staff's frequent movements. The connection strength test between the wire and the measuring mechanism 2 is completed by pulling the wire downward sharply by the cleaning roller 149. If a detachment occurs, the staff can be notified in time for maintenance, avoiding the interruption of the electrical signal measuring work due to detachment caused by external force in subsequent use.

[0033] like Figures 1-8 As shown, based on the above embodiments, another embodiment of the present invention further includes a straightening device 15; The straightening device 15 includes a through rod 151, which is inserted through the outer wall of the through rod 151 and fixedly installed inside the top of the T-shaped plate 148. Fixed plates 152 are fixedly installed at both ends of the through rod 151. A number of fixed plates 152 are rotatably installed between each other and close to one side. The number of pressure rollers 153 straighten the line by means of the upper and lower position difference.

[0034] A reciprocating screw 154 is fixedly installed through the side wall of the extrusion roller 153. The outer wall of the reciprocating screw 154 is a non-self-locking reciprocating spiral groove. A push plate 155 is movably installed through the outer wall of the reciprocating screw 154. A limit rod 156 is fixedly installed on the middle side wall of the push plate 155. The limit rod 156 is slidably installed inside the T-shaped plate 148 through the outer wall of the limit rod 156. An L-shaped slotted plate 157 is fixedly installed through the outer wall of the limit rod 156.

[0035] The limiting rod 156 limits the horizontal relationship between the extrusion roller 153 and the T-shaped plate 148. The outer wall of the vertical end of the T-shaped plate 148 is located on the internal movement trajectory of the L-shaped slotted plate 157. The L-shaped slotted plate 157 detects whether there is lateral separation between the T-shaped plate 148 and the telescopic end of the elastic telescopic rod 147.

[0036] The rotation and straightening of the extrusion roller 153 eliminates the need for workers to manually adjust the bent parts of the wires. The built-in mechanical structure improves the straightness of the wires, ensuring the neatness of the overall wiring layout. This facilitates quick wiring repairs in case of subsequent faults and prevents the removal of the external insulation layer at the wire connection points from becoming more difficult due to bending. The through rod 151 ensures that the extrusion roller 153 remains horizontal to the vertical plane of the T-shaped plate 148, preventing unidirectional tilting during long-term use and thus reducing the straightening effect on the wires. Furthermore, the movement of the L-shaped slotted plate 157 is monitored for obstruction, providing a reference standard for determining whether the extrusion roller 153 is horizontal and improving the accuracy of the judgment.

[0037] In use, the wire passes between several symmetrically distributed compression rollers 153 at different heights during threading. Simultaneously, the compression rollers 153 are limited by a fixed plate 152, which in turn is limited by a through rod 151, which is limited by a T-shaped plate 148. Therefore, when the cleaning roller 149 adjusts its spacing, the through rod 151 adjusts the spacing of the compression rollers 153 via the T-shaped plate 148. Since the circumferential surfaces of the compression rollers 153 and the cleaning roller 149 are on the same horizontal plane, friction is generated between the external surfaces of the wire and the compression rollers 153. At this time, the compression rollers 153, with their varying heights, rotate and straighten any twisted portions of the wire. When the rear through rod 151 moves down, it causes the extrusion roller 153 to move synchronously, freeing up more operating space for manual connection by the operator. When the extrusion roller 153 rotates, it drives the reciprocating screw 154 to rotate. The reciprocating screw 154 guides the built-in locking block of the push plate 155 through the non-self-locking reciprocating spiral groove on its outer wall. The push plate 155 drives the limiting rod 156 to slide horizontally back and forth along the inside of the T-shaped plate 148. At this time, the limiting rod 156 limits the extrusion roller 153, and the limiting rod 156 drives the L-shaped slotted plate 157 to move outward of the T-shaped plate 148. At this time, the operator can observe whether the inside of the L-shaped slotted plate 157 can smoothly penetrate into the outer wall of the T-shaped plate 148.

[0038] According to the above embodiments, the rotation and straightening of the extrusion roller 153 eliminates the need for workers to manually adjust the bent parts of the wires. The built-in mechanical structure improves the straightness of the wires, ensuring the neatness of the overall wiring layout. This facilitates quick wiring repairs in case of subsequent faults and prevents the removal of the external insulation layer at the wire connection end from becoming more difficult due to bending. The through rod 151 ensures that the extrusion roller 153 remains horizontal to the vertical plane of the T-shaped plate 148, preventing unidirectional tilting during long-term use and thus reducing the straightening effect on the wires. At the same time, the movement of the L-shaped slotted plate 157 is checked for obstruction, providing a reference standard for whether the extrusion roller 153 is horizontal and improving the accuracy of the judgment.

[0039] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
