[0061] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0062] like Figure 1-12 As shown, the present invention provides a technical solution: a quick connection device for a fast power distribution cabinet, comprising a fixing structure 1, a support device 2, an installation device 3, and a positioning device 4.
[0063] Reference Figure 1 and Figure 2 The fixing structure 1 includes a box 11. In this embodiment, the box 11 is preferably a rectangular fixing structure 1, and any side wall of the box 11 is provided with a receiving cavity 12 in the horizontal direction. The box 11 is provided with a plurality of heat dissipation holes 13 at the bottom of the receiving cavity 12 opening direction. The heat dissipation holes 13 are horizontally arranged and are connected to the inner cavity of the receiving cavity 12. Each heat dissipation hole 13 is provided with a fan in its inner cavity. Here, the blowing direction of the fan is from the axial direction of the placement slot from the inside of the box 11 to the outside of the box 11.
[0064] Reference Figure 1 The side wall of the box 11 is provided with multiple wire-laying holes 14 running horizontally through it.
[0065] Reference Figure 1 Each corner of the bottom wall of the housing 11 is provided with a caster 15. In this embodiment, the caster 15 is preferably a universal caster 15 with a locking structure. The outer shell of the caster 15 is fixedly connected to the housing 11 by screws.
[0066] The inclusion cavity 12 allows operators to install the corresponding electrical equipment in a suitable position within the housing 11 and fix its position, thus making better use of the inclusion cavity 12. The casters 15 make it easy for operators to push the housing 11, thereby completing rapid movement and positioning. At the same time, the locking structure ensures that the casters 15 will not rotate arbitrarily during movement, ensuring the safety and convenience of operation.
[0067] Reference Figure 1 The fixed structure 1 also includes a door 16, which is located at the opening end of the receiving cavity 12 and is rotatably connected to the box body 11 by means of a hinge. The rotation axis of the door 16 is vertical. An observation groove 17 is provided through the door 16 in the horizontal direction. The inner cavity of the observation groove 17 is provided with glass, which is fixedly connected to the door 16 by adhesive.
[0068] The enclosure door 16 can seal the receiving cavity 12. The observation slot 17 is equipped with glass, which allows operators to visually inspect and monitor the internal status when installing and maintaining electrical equipment, ensuring the safety and efficiency of the operation.
[0069] Reference Figure 1 , Figure 2 and Figure 3The support device 2 is installed in the inner cavity of the placement slot. The support device 2 includes a track part 21. In this embodiment, there are two track parts 21. The two track parts 21 are arranged in sequence along the opening direction of the placement slot. The track parts 21 are horizontally arranged, and the long side of the track part 21 is perpendicular to the opening direction of the receiving cavity 12. Here, the track part 21 is preferably a T-shaped rod. The track part 21 is fixedly connected to the box body 11 by screw fixing.
[0070] Reference Figure 1 , Figure 2 and Figure 3 The support device 2 also includes a mounting base 22, which includes a support plate 221. The support plate 221 is preferably a rectangular rod. The long side of the support plate 221 is parallel to the long side of the track section 21. The bottom wall of the support plate 221 is provided with two receiving grooves 222. Each receiving groove 222 is used to receive a track section 21, so that the support plate 221 can slide along the long side of the track section 21.
[0071] The track section 21 provides support for the sliding of the support plate 221. At the same time, the support plate 221 can move smoothly along the long side of the track section 21, allowing the support plate 221 to reach any position in the receiving cavity 12. This makes it convenient for operators to adjust the position of the equipment according to actual needs, ensuring the accurate positioning of electrical equipment during installation and adjustment, and improving the overall applicability of the device.
[0072] Reference Figure 1 and Figure 3 The support plate 221 has positioning holes 223 at both ends of its long side. Each positioning hole 223 has a connecting rod 224 and a first cam 225 inside its cavity. The connecting rod 224 passes through the support plate 221 and is rotatably connected to the support plate 221 by means of a bearing. The first cam 225 is located in the positioning hole 223 and is coaxially fixedly connected to the connecting rod 224 by means of a key connection. In this embodiment, when the first cam 225 has its maximum stroke vertically downward, the side wall of the first cam 225 can fit against the bottom wall of the housing 11.
[0073] Reference Figure 3 A handwheel 226 is provided at the end of the connecting rod 224 away from the first cam 225, and the handwheel 226 is coaxially and fixedly connected to the connecting rod 224 by a key connection.
[0074] Reference Figure 3 The outer wall of the first cam 225 is provided with an anti-slip coating, which can effectively increase the friction between the first cam 225 and the housing 11.
[0075] The support plate 221 has positioning holes 223 at both ends of its long side, in which connecting rods 224 and first cams 225 are installed. The operator can rotate the connecting rods 224, which in turn drives the first cams 225 to rotate, so that the side wall of the first cams 225 is pressed tightly against the bottom wall of the housing 11, thereby achieving a stable positioning of the support plate 221. This design not only improves the stability of the device, but also simplifies the operation process and ensures the accuracy of equipment installation and adjustment.
[0076] Reference Figure 2 and Figure 4 Each support device 2 is equipped with a mounting frame 23. In this embodiment, the mounting frame 23 is preferably a hollow rectangular frame. The mounting frame 23 is vertically arranged, and the opening direction inside the rectangular frame is parallel to the opening direction of the receiving cavity 12. The mounting frame 23 is connected to the support plate 221 by screw fixing. The side wall of the mounting frame 23 is provided with multiple fixing holes 231. Each fixing hole 231 is provided with a support wheel 232 in its inner cavity. The support wheel 232 is rotatably connected to the mounting frame 23 by bearing connection, and the rotation axis of the support wheel 232 is perpendicular to the opening direction of the mounting frame 23. The outer wall of the support wheel 232 can always fit against the top wall of the track part 21.
[0077] The mounting bracket 23 is a hollow rectangular frame. This design is both lightweight and sturdy, facilitating installation and transportation. The fixing holes 231 provide support for the mounting of the support wheels 232, ensuring their stability and durability. Each support wheel 232 can rotate independently, and its outer wall fits against the inner wall of the housing 11, thus providing better positioning for the mounting bracket 23 and reducing friction between the mounting bracket 23 and the housing 11.
[0078] Reference Figure 2 The top of the inner cavity of the mounting bracket 23 is provided with a mounting groove 233 in the vertical direction, and the opening direction of the mounting groove 233 is vertically downward; the top of the mounting bracket 23 is provided with an adjustment groove 234 in the horizontal direction, the long side of the adjustment groove 234 is parallel to the long side of the mounting groove 233, and the inner cavity of the adjustment groove 234 is connected to the inner cavity of the mounting groove 233.
[0079] Reference Figure 2 Each mounting bracket 23 is equipped with multiple mounting devices 3. The mounting device 3 includes an adjusting block 31, a gripping part 32, and a support rod 33. The adjusting block 31 is located in the adjusting groove 234 and can slide along the long side of the adjusting groove 234. The support rod 33 is vertically arranged and passes through the mounting groove 233. The bottom of the adjusting block 31 is provided with a threaded groove in the vertical direction. The top wall of the support rod 33 is provided with a threaded section, which passes through the threaded groove. The adjusting block 31 and the support rod 33 are detachably connected through the threaded connection between the threaded groove and the threaded section. In this embodiment, an installation gap is left between the bottom wall of the support rod 33 and the mounting bracket 23.
[0080] The mounting slot 233 is designed for mounting the support rod 33. Its opening faces vertically downwards, facilitating insertion of the support rod 33 from the top. The adjusting block 31 allows the operator to easily adjust the position of the support rod 33, ensuring its precise placement. The grip 32 is located above the adjusting block 31, facilitating adjustment and fixation by the operator. This structure allows the support rod 33 to be moved freely, making better use of the space within the housing 11.
[0081] Reference Figure 2 and Figure 5 The mounting device 3 also includes a mounting block 34. In this embodiment, the mounting block 34 is preferably a rectangular block. The top wall of the mounting block 34 is provided with a through hole 341 in the vertical direction. The through hole 341 is used to accommodate the support rod 33, so that the mounting block 34 can slide along the axis of the support rod 33. The end face of the mounting block 34 near the opening of the receiving cavity 12 is provided with a mounting hole 342 in the horizontal direction. Here, the mounting hole 342 is preferably a rectangular hole. The inner cavity of the mounting hole 342 is provided with a damping shaft 343 and a second cam 344. The damping shaft 343 is horizontally arranged. The fixed part of the damping shaft 343 is fixedly connected to the mounting block 34. The second cam 344 and the rotating part 46 of the damping shaft 343 are coaxially fixedly connected. In this embodiment, when the rotating part 46 of the damping shaft 343 is in the initial position, the end face of the second cam 344 away from the damping shaft 343 is attached to the side wall of the support rod 33. The side wall of the second cam 344 is provided with an anti-slip layer.
[0082] The operator can slide the mounting block 34 to a suitable height. At this time, the second cam 344 rotates along the damping shaft 343. At this time, the maximum stroke of the second cam 344 does not contact the support rod 33. When it reaches the preset position, the mounting block 34 is slid in the opposite direction so that the maximum stroke of the second cam 344 contacts the support rod 33, thereby completing the locking of the mounting block 34.
[0083] Reference Figure 6 Each mounting block 34 has a top wall with a plug groove 345, which is vertically arranged. The two side walls of the plug groove 345 are provided with locking holes 346, and the inner cavities of the plug groove 345 and the locking holes 346 are connected.
[0084] Reference Figure 6 and Figure 7The end face of the connecting block 354 away from the support rod 33 is provided with an installation structure 35. The installation structure 35 includes an abutment plate 351, a connecting plate 352, and a snap-fit plate 353. In this embodiment, the abutment plate 351, the connecting plate 352, and the snap-fit plate 353 are all rectangular plates and are arranged sequentially along the opening direction of the receiving cavity 12. The abutment plate 351 is provided with a connecting block 354. Each mounting block 34 is provided with a connecting block 354. The connecting block 354 passes through the insertion groove 345 and can slide along the opening direction of the insertion groove 345. Both sides of the connecting block 354 are provided with a first spring 355 and a locking block 356. The first spring 355 is vertically arranged. The locking block 356 and the connecting block 354 are connected by the first spring 355. The locking hole 346 is used to accommodate the locking block 356. In this embodiment, when the locking block 356 is located in the locking hole 346, the connecting block 354 extends into the through groove and abuts against the support rod 33. The end face of the connecting block 354 near the support rod 33 is provided with a friction pad 357, wherein the friction pad 357 has a certain deformation capability.
[0085] When the abutment plate 351 needs to be installed, the operator only needs to insert the connecting block 354 into the insertion slot 345 and position the locking block 356 in the locking hole 346. The setting of the friction pad 357 can more stably fix the abutment plate 351 to the mounting block 34.
[0086] Reference Figure 7 The middle array of the abutment plate 351 is provided with a first heat dissipation groove 3511, which runs horizontally through the plate. The diameter of the first heat dissipation groove 3511 gradually increases along the opening direction of the receiving cavity 12.
[0087] Reference Figure 7 The connecting plate 352 is detachably connected to the abutment plate 351 by a snap-fit connection. The end face of the connecting plate 352 away from the abutment plate 351 is provided with a second heat dissipation groove 3521. In this embodiment, the second heat dissipation groove 3521 is arranged in a spiral along the surface of the connecting plate 352, and the second heat dissipation groove 3521 is a V-shaped groove. The connecting plate 352 is provided with a third heat dissipation groove 3522 at intervals at the second heat dissipation groove 3521. Multiple third heat dissipation grooves 3522 are arranged at intervals along the second heat dissipation groove 3521.
[0088] Reference Figure 7 The snap-fit plate 353 is used to install corresponding electrical components. The snap-fit plate 353 is detachably connected to the connecting plate 352 by a snap-fit connection. The snap-fit plate 353 has a fourth heat dissipation groove 3531 arranged in an array on the end face of the snap-fit plate 352 near the connecting plate 352. Here, the fourth heat dissipation groove 3531 penetrates the snap-fit plate 353, and the opening direction of the fourth heat dissipation groove 3531 is horizontal. In this embodiment, the diameter of the openings at both ends of the fourth heat dissipation groove 3531 is larger than the diameter of the middle part of the fourth heat dissipation groove 3531.
[0089] Reference Figure 7 Here, the inner cavities of the first heat dissipation slot 3511, the second heat dissipation slot 3521, the third heat dissipation slot 3522 and the fourth heat dissipation slot 3531 are connected.
[0090] Reference Figure 7 In this embodiment, the abutment plate 351, connecting plate 352 and snap-fit plate 353 are made of polypropylene, polyethylene and other materials that have certain stress and are insulating.
[0091] The operator first inserts the locking blocks 356 on both sides of the connecting block 354 into the locking holes 346 to complete the installation of the abutment plate 351 on the connecting block 354. The operator then installs the relevant electrical components on the snap-fit plate 353. The heat generated by the electrical components first passes through the fourth heat dissipation groove 3531. The diameters at both ends of the fourth heat dissipation groove 3531 are larger than the diameter in the middle, which can effectively conduct heat. Then it enters the second heat dissipation groove 3521 of the connecting plate 352. The second heat dissipation groove 3521 can effectively collect heat. Then it passes through the third heat dissipation groove 3522 and through the connecting plate 352, so that the heat can enter the external environment through the first heat dissipation groove 3511. At the same time, the first heat dissipation groove 3511, the second heat dissipation groove 3521, the third heat dissipation groove 3522 and the fourth heat dissipation groove 3531 can increase the contact area between the device and the air, thereby enabling better heat dissipation.
[0092] Reference Figure 2 The snap-fit plate 353 is provided with locking components 37 on both sides in the vertical direction.

The end face of the positioning plate 391 away from the rotating shaft is provided with a positioning groove 392. Both ends of the positioning groove 392 are provided with support shafts 393. In this embodiment, the support shaft 393 is preferably a circular shaft. The support shaft 393 is perpendicular to the positioning plate 391, and the support shaft 393 and the snap-fit plate 353 are fixedly connected by means of screws.
[0095] The operator can place the component to be installed on the snap-fit plate 353 and press it down. At this time, the component contacts the first chamfer of the clamping plate 372, and the two clamping plates 372 slide away from each other. The clamping plates 372 provide positioning for the component on both sides. Then the component abuts against the receiving plate 382. The edge of the receiving plate 382 is stepped. The component abuts against the stepped position of the receiving plate 382. Under the action of the second chamfer, the component can fit properly against the corresponding step. Then the receiving plate 382 supports the component from below. When the component reaches the appropriate position, the snap-fit plate 353 is rotated to limit the top of the component, thereby ensuring the stability of the component during installation and use.
[0096] Reference Figure 2 and Figure 8 Multiple positioning devices 4 are installed at the support shaft 393, and the multiple positioning devices 4 are arranged sequentially along the axial direction of the support shaft 393.
[0097] Reference Figure 2 and Figure 8 The positioning device 4 includes a mounting rod 41. In this embodiment, the mounting rod 41 is preferably a rectangular rod. The mounting rod 41 is sleeved on the support shaft 393 and is rotatably connected to the support shaft 393 by means of a bearing connection. The mounting rod 41 is provided with a sliding groove 42, wherein the opening direction of the sliding groove 42 is parallel to the axial direction of the support shaft 393, and the long side direction of the sliding groove 42 is parallel to the long side direction of the mounting rod 41.
[0098] Reference Figure 2 and Figure 8 The inner cavity of the sliding groove 42 is provided with multiple support blocks 43, and the support blocks 43 can slide along the long side of the sliding groove 42. The support blocks 43 are provided with a receiving hole 431 through them. The axial direction of the receiving hole 431 is parallel to the axial direction of the support shaft 393. The support blocks 43 are provided with a fixing groove 432 coaxially with the receiving hole 431. In this embodiment, both the receiving hole 431 and the fixing groove 432 are circular holes.
[0099] When the operator is connecting the relevant components, he only needs to rotate the mounting rod 41 along the support shaft 393, and then let the support block 43 slide along the sliding groove 42, so that the support block 43 reaches the relevant position of the component and the wire passes through the receiving hole 431, thereby completing the positioning of the wire and preventing the wire from shaking, which would affect the connection stability between the wire and the component.
[0100] Reference Figure 8 and Figure 9 The top of the receiving hole 431 is provided with a positioning ring 44. In this embodiment, the positioning ring 44 is preferably a circular ring and is horizontally arranged. The positioning ring 44 and the receiving cylinder are coaxially arranged. The outer wall of the positioning ring 44 is evenly distributed with multiple protrusions. The two ends of the protrusions are fixedly connected to the positioning ring 44 and the support block 43, respectively.
[0101] The positioning ring 44 further limits the position of the circuit, thereby ensuring that the circuit remains perpendicular during the connection with the component, which can better improve the connection stability between the circuit and the component.
[0102] Reference Figure 9 The support block 43 is provided with multiple limiting grooves 433 on the bottom wall of the fixing groove 432. In this embodiment, the number of limiting grooves 433 is preferably four, and the four limiting grooves 433 are evenly distributed circumferentially along the axial direction of the limiting groove 433. The limiting grooves 433 are preferably arc-shaped grooves, and the four limiting grooves 433 together form a ring.
[0103] Reference Figure 10 , Figure 11 and Figure 12Each limiting groove 433 is equipped with an abutment 45, which includes a slider 451, a second spring 452, a fixing tube 453, a guide block 454, an abutment rod 455, a third spring 456, and a fourth spring 457. The slider 451 is located in the limiting groove 433 and slides back and forth along the limiting groove 433 via an elastic element. The extension and retraction direction of the second spring 452 is parallel to the long side of the limiting groove 433. The two ends of the second spring 452 are fixedly connected to the support block 43 and the slider 451, respectively. The axial direction of the fixing tube 453 is radial to the receiving hole 431. The bottom wall of the fixing tube 453 is provided with an directional groove, and the long side of the directional groove is parallel to the fixing tube 451. In the axial direction of 3, the guide block 454 is located on the top wall of the fixed tube 453, and the top wall of the guide block 454 is attached to the top wall of the fixed groove 432. The fixed tube 453 and the guide block 454 are fixedly connected. The abutment rod 455 passes through the inner cavity of the fixed tube 453 and can slide along the axial direction of the fixed tube 453. The third spring 456 is located in the inner cavity of the fixed tube 453, and the two ends of the third spring 456 are fixedly connected to the fixed tube 453 and the abutment rod 455 respectively. The slider 451 extends into the directional groove. The fourth spring 457 is located in the directional groove, and the extension and retraction direction of the fourth spring 457 is parallel to the directional groove. The two ends of the fourth spring 457 are fixedly connected to the slider 451 and the support block 43 respectively.
[0104] After passing through the positioning ring 44, the operator squeezes the abutment rod 455, allowing the abutment rod 455 to slide along the fixed tube 453. This allows the end of the abutment rod 455 to better abut against the line, thereby better limiting the line and preventing displacement of the line during the connection process.
[0105] Reference Figure 10 , Figure 11 and Figure 12 The end of the abutment rod 455 away from the fixed tube 453 is provided with two rotating parts 46. The two rotating parts 46 are symmetrically arranged in the vertical direction. The rotating parts 46 are rotatably connected to the abutment rod 455 by means of torsion spring connection. The rotation axis of the rotating parts 46 is vertical. In this embodiment, the top of the rotating parts 46 is provided with a third chamfer.
[0106] Reference Figure 10 , Figure 11 and Figure 12 Each rotating part 46 has an abutment wheel 47 on its end face near the axis of the rotating receiving hole 431. The axis of rotation of the abutment wheel 47 is horizontal, and the surface of the abutment wheel 47 is provided with an elastic pad with a large number of anti-slip textures.
[0107] The rotating part 46 is designed to rotate along the abutment rod 455, allowing it to better fit against the side wall of the line and further improve the limiting effect of the abutment rod 455 on the line. The abutment wheel 47 can reduce the friction between the line and the abutment rod 455 to a certain extent. The elastic pad allows the abutment wheel 47 to better clamp the line. At the same time, the anti-slip texture prevents the line from sliding along the abutment wheel 47 after it is fixed, thus preventing the connection stability of the line from being affected.
[0108] Reference Figure 10 , Figure 11 and Figure 12 Each guide block 454 is equipped with a reset member 48, which is installed in the fixing groove 432 and located at the top of the fixing tube 453. The guide block 454 is always in contact with the side wall of the reset member 48. In this embodiment, the horizontal cross section of the end face of the guide block 454 in contact with the reset member 48 is preferably a spiral surface. As the fixing tube 453 rotates, the distance between the guide block 454 and the axis of the receiving hole 431 gradually increases. The end of the reset member 48 near the axis of the receiving hole 431 is arc-shaped and has a sawtooth cross section at the arc surface. In this embodiment, the average distance between adjacent peaks and troughs is the same as the distance to the axis of the receiving hole 431.
[0109] When the wiring needs to be adjusted or removed, the abutment wheel 47 and the rotating part 46 provide a limit to the wiring. At this time, the operator only needs to rotate the wiring, which will drive the abutment rod 455 and the fixing tube 453 to rotate along the limiting groove 433. The guide block 454 is limited by the reset part 48 until the guide block 454 reaches the serrated part of the reset part 48. At this time, the fixing tube 453 will generate a certain vibration, causing the fixing tube 453 to slide radially along the receiving hole 431, driving the rotating part 46 and the abutment wheel 47 away from the wiring, releasing the limitation on the wiring. At this time, the operator can remove the wiring as soon as possible. At the same time, the third spring 456 drives the slider 451 to return to its original position, that is, the fixing tube 453 and the abutment rod 455 slowly return to their initial positions, which makes it easier for the operator to carry out subsequent related operations.
[0110] The implementation principle of a quick connection device for a fast power distribution cabinet is as follows: The operator first moves the cabinet 11 to a suitable position, then slides the support plate 221 along the long side of the track 21 to a suitable position, and then rotates the connecting rod 224 so that the first cam 225 can abut against the cabinet 11, thereby fixing the position of the support plate 221 and fixing the position of the mounting bracket 23. At the same time, the setting of the support wheel 232 can ensure that the mounting bracket 23 is in a vertical state and reduce the friction between the mounting bracket 23 and the cabinet 11.
[0111] Then, by using the grip 32, the position of the sliding adjustment block 31 is adjusted. According to the number and position of the components to be installed, an appropriate number of mounting blocks 34 are then installed. The mounting blocks 34 are then slid to the appropriate position. During the sliding process, the maximum stroke of the second cam 344 does not contact the support rod 33. When the appropriate position is reached, or the mounting blocks 34 are slid in the opposite direction, the maximum stroke of the second cam 344 contacts the support rod 33, thus completing the fixation of the position of the mounting blocks 34.
[0112] Once the desired position is reached, press the connecting block 354 so that it abuts against the insertion slot 345, and simultaneously position the locking block 356 in the locking hole 346, thus fixing the positions of the mounting block 34 and the abutment plate 351.
[0113] The operator then installs the component to be installed, using the clamping plates 372 on both sides to position the two sides of the component, and using the receiving plate 382 to support the bottom of the component. The positioning plate 391 is then rotated to complete the positioning of the component.
[0114] The heat generated by the relevant electrical appliances will first pass through the fourth heat dissipation slot 3531 and the snap-fit plate 353, and then the heat will enter the second heat dissipation slot 3521. As the heat flows through the second heat dissipation slot 3521, it will enter the fourth heat dissipation slot 3531 through the third heat dissipation slot 3522, and then leave the abutment plate 351. At the same time, the first heat dissipation slot 3511, the second heat dissipation slot 3521, the third heat dissipation slot 3522 and the fourth heat dissipation slot 3531 can increase the heat dissipation area and improve the heat dissipation speed.
[0115] When installing the relevant wiring, the operator only needs to rotate the mounting rod 41 along the support shaft 393, and then slide the support block 43 so that the receiving hole 431 of the support block 43 connects with the wire insertion hole of the component. The wiring is slid along the receiving hole 431, first passing through the positioning ring 44, and then abutting against the rotating part 46 and the abutting wheel 47. During this process, the abutting wheel 47 can reduce the friction between the rotating part 46 and the wiring to a certain extent, ensuring the smooth passage of the wiring. After the wiring is installed in place, the wiring and components are positioned.
[0116] When it is necessary to loosen the wire, the operator simply rotates the wire. The wire is then limited by the rotating part 46, which in turn rotates the abutment rod 455 and the fixing tube 453. At this point, the guide block 454 and the reset member 48 are released until the abutment block contacts the serrated part of the reset member 48. The fixing tube 453 then reaches its position furthest from the axis of the receiving hole 431. At this point, the rotating part 46 no longer contacts the wire, releasing its limiting effect. The operator can then easily remove the wire from the receiving hole 431. After removal, the fixing tube 453 and the abutment rod 455 return to their initial positions under the action of the third spring 456 and the fourth spring 457, providing support for subsequent operations.
