Description

Technical Field

[0001] This invention relates to the field of automatic pin processing technology, specifically to an automatic pin processing device with multiple workstations. Background Technology

[0002] With the rapid development of the electronics industry, the demand for electrical connectors (plugs) and their respective connectors is increasing. Electronic pins are widely used in various electronic components such as electrical connectors, automotive connector terminals, and computer connector terminals, possessing excellent mechanical, electrical, and environmental performance. Currently, there are... Figure 8 The pin 01 shown is manufactured from round copper wire through a cutting process and multiple processing steps. Since recessed holes 02 and round heads 03 need to be formed at both ends of the pin, and a ring-shaped boss 04 needs to be formed on the side wall of the pin, this pin requires grinding the round head in machine tool one (specifically a lathe or grinding machine), drilling the recessed holes in machine tool two, and finally punching the boss in machine tool three. Only after these three processing steps can the finished pin be obtained. Therefore, the production process of this pin requires two lathes and a punch press to complete the corresponding processes. Each process must be operated independently. This not only results in multiple machines occupying a large space and a cumbersome production process, but also requires multiple feeding and unloading operations. The lack of coordination between processes and the long waiting times slow down the production pace, affect the overall production progress, reduce production efficiency, and increase production costs. Summary of the Invention

[0003] Therefore, the technical problem to be solved by the present invention is to overcome the problem that the pin insertion production process in the prior art requires the use of multiple lathes and punch presses to complete, the production process is relatively cumbersome, the connection between each process is not coordinated, which slows down the production pace, reduces production efficiency, and increases production costs.

[0004] To address the aforementioned problems, this invention provides a multi-station automatic processing equipment for pin insertion, comprising a cutting mechanism, a material handling mechanism, and a pin processing system mounted on a frame. The cutting mechanism cuts the fed copper wire into pins to be processed. The material handling mechanism has a movable material handling station located on one side of the cutting mechanism. The pin processing system includes multiple pin processing devices arranged parallel to and spaced apart from the cutting mechanism, and a pushing device arranged opposite to the multiple pin processing devices. Multiple material release stations are located on the moving path of the material handling mechanism between the pushing device and the multiple pin processing devices. The material handling station and multiple feeding stations reciprocate between each other to pick up the copper pin parts from the picking station and feed them sequentially to the multiple feeding stations. Multiple pushing devices move synchronously towards or away from the multiple pin processing devices, thereby pushing the copper pin parts at the multiple feeding stations into the multiple pin processing devices respectively. The pin processing devices push the processed copper pin parts back to the corresponding feeding station, where they can be picked up again by the picking mechanism and sent to the next station. The copper pin parts are formed into finished pins after the multiple pin processing devices complete the rounding, groove punching, and boss punching processes respectively.

[0005] In the aforementioned automatic processing equipment for multi-station pin insertion, a movable gap is formed between the pushing device and the multiple pin insertion processing devices. The picking mechanism includes multiple picking grippers spaced apart for gripping the copper pin parts. The picking mechanism drives the multiple picking grippers to reciprocate within the movable gap along its length.

[0006] In the aforementioned automatic processing equipment for multi-station insertion pins, the pushing device includes a mounting base disposed on one side of the movable gap and a station slider movably disposed on the mounting base, and multiple push rod structures disposed at intervals in multiple guide holes at one end of the station slider. Under the drive of the station slider, the multiple push rod structures push the copper pins in the multiple material handling grippers into the multiple insertion pin processing devices respectively.

[0007] In the aforementioned multi-station automatic processing equipment for insert pins, the multiple insert pin processing devices each include a primary rounding device, a secondary rounding device, and an integrated stamping device arranged sequentially at intervals on the other side of the movable gap. The primary rounding device, the secondary rounding device, and the integrated stamping device are respectively arranged opposite to multiple push rod structures. The copper insert pin is first fed into the primary rounding device to complete the initial pre-rounding processing, then fed into the secondary rounding device to complete the final rounding processing, and finally fed into the integrated stamping device to complete the processing of punching grooves and punching bosses.

[0008] In the aforementioned automatic processing equipment for multi-station needle insertion, four material pickers are provided on the material pickering mechanism, and three material release stations are respectively provided at the opening ends of the primary rounding device, the secondary rounding device, and the integrated stamping device. The material pickering gripper at the first position is opposite to the cutting mechanism at the material pickering station, and the other three material pickers are opposite to the primary rounding device, the secondary rounding device, and the integrated stamping device at the three material release stations, respectively.

[0009] In the aforementioned automatic processing equipment for multi-station pin insertion, the frame is provided with a discharge port located after the feeding station on the moving path of the material handling mechanism. When the last material handling gripper moves back and forth, it drives the finished pin to the top of the discharge port. The mold fixing plate is also provided with an ejector mold to push the finished pin into the discharge port.

[0010] In the aforementioned automatic processing equipment for multi-station pin insertion, the pin insertion processing system includes a mold fixing plate disposed on the other side of the movable gap, and the primary rounding device, the secondary rounding device, and the integrated stamping device are respectively mounted on the mold fixing plate.

[0011] In the aforementioned automatic processing equipment for multi-station pin insertion, the material handling mechanism includes a sliding bar that can be reciprocated and moved on the mold fixing plate, and multiple material handling grippers are sequentially and spaced apart on the sliding bar and move with the sliding bar. The mold fixing plate extends along the moving direction of the material handling mechanism and is provided with a material handling groove that allows the sliding bar to move.

[0012] In the aforementioned automatic processing equipment for multi-station pin insertion, a power assembly structure connecting the material handling mechanism and the pin insertion processing system is also installed on the frame. The power assembly structure includes a power shaft and a material handling drive cam linked to the power shaft. One end of the sliding bar is connected to the material handling drive cam through a roller bearing, and a first spring is provided between the other end of the sliding bar and the material handling groove.

[0013] In the aforementioned automated multi-station processing equipment for inserting pins, the cutting mechanism includes:

[0014] The mounting base has guide grooves extending through both ends of it;

[0015] The drive rod is reciprocally mounted in the guide groove;

[0016] The cutting block is linked to the drive rod and has a cutting edge structure that extends out of one end of the guide groove, so that the copper wire passes straight through the cutting edge structure.

[0017] The pressure block is oscillatingly disposed between the guide groove and the cutting block. The pressure block has a pressed state in which it engages with the cutting edge structure to press the copper wire, and an open state in which it separates from the cutting edge structure to release the copper wire. The drive rod drives the cutting block in the pressed state to move and cut the copper wire into a section of pin copper part.

[0018] The push rod assembly is inserted into the guide groove and connected to the pressure block, and is used to drive the pressure block to switch between the pressed state and the open state.

[0019] In the aforementioned automatic processing equipment for multi-station needle insertion, a cutting drive cam is linked to the power shaft, one end of the drive rod is connected to the cutting drive cam, and a second spring is provided between the other end and the guide groove. A stepped groove suitable for installing the cutter block and the pressure block is formed on the side of the drive rod.

[0020] The technical solution of the present invention has the following advantages compared with the prior art:

[0021] 1. In the multi-station automatic processing equipment for pins provided by the present invention, copper wire is first cut into pin copper parts to be processed by a cutting mechanism. Then, the pin copper parts are sequentially fed from the picking station to multiple unloading stations by a material picking mechanism. Each unloading station corresponds to a pin processing device. During the processing steps, the pin copper parts at the multiple unloading stations are pushed into the multiple pin processing devices by a pushing device. These pin processing devices push the processed pin copper parts back to their respective unloading stations, where they are then picked up by the picking mechanism and sent to the next station. This process is repeated until all the processing steps of the pins are completed, thus ensuring that each pin copper part sequentially enters multiple pin processing devices. In the pin processing device, the pins are formed into finished products after completing the rounding, groove punching, and boss punching processes. This automated processing equipment directly processes the cut pin copper parts through multiple pin processing devices to complete the rounding, groove punching, and boss punching processes. The coordination and connection between each process is reliable, realizing the entire production process of pins from raw material cutting, station feeding, and processing. It reduces the waiting time of each process, which helps to speed up the production rhythm and shorten the total production time. It makes the time to complete the production of a pin product shorter, improves production efficiency, and realizes automated processing operation throughout the entire process. This not only ensures product quality but also reduces labor costs and significantly improves the degree of automation in pin production.

[0022] 2. In the multi-station automatic processing equipment for insert pins provided by the present invention, the pushing device includes multiple push rod structures spaced apart on one end of the station slider. These push rod structures are opposite to the open ends of multiple insert pin processing devices. When multiple pick-up grippers move to multiple unloading stations, the station slider moves towards the side closer to the insert pin processing device, and drives the multiple push rod structures to push against the ends of multiple insert pin copper parts respectively, thereby pushing the multiple insert pin copper parts into the multiple insert pin processing devices. The multiple insert pin processing devices perform corresponding processing on the insert pin copper parts at their respective positions. After processing is completed, the insert pins are pushed out of the insert pin processing devices by the push rods and can be picked up by the returning pick-up grippers. This structural arrangement allows the insert pin copper parts on the pick-up grippers to be accurately fed into the insert pin processing devices through the push rod structures, realizing the feeding and transfer of insert pin copper parts between the pick-up grippers and the insert pin processing devices. The design is reasonable and the cooperation is accurate and reliable.

[0023] 3. In the multi-station automatic processing equipment for inserts provided by the present invention, the multiple insert processing devices are a primary rounding device, a secondary rounding device, and an integrated stamping device arranged sequentially at intervals. The feeding station is provided with three corresponding openings at the primary rounding device, the secondary rounding device, and the integrated stamping device. Since the round head formed by the initial rounding of the insert is relatively rough, the secondary rounding is required to achieve a smooth finish. The integrated stamping device can complete two processes: punching grooves and punching bosses on the insert. By reasonably optimizing the structural components, the number of insert processing devices can be reduced. With this structural setup, the processing sequence of each insert is to pass through the primary rounding device, the secondary rounding device, and the integrated stamping device in sequence to finally become a finished insert. The finished insert will fall into the discharge port under the gripping of the material handling hand.

[0024] 4. In the multi-station automatic processing equipment for insert pins provided by the present invention, the sliding bar is movably set in the material picking groove of the mold fixing plate. A material picking drive cam is set on the power shaft. One end of the sliding bar is connected to the material picking drive cam through a roller bearing, and a first spring is set between the other end and the material picking groove. With this structure, the first spring applies an elastic force to the sliding bar to keep it in contact with the material picking drive cam. Since the sliding bar slides in contact with the outer periphery of the material picking drive cam through the roller bearing, by reasonably designing the outer periphery motion trajectory of the material picking drive cam, the drive cam rotates once, which drives the sliding bar to move back and forth along the material picking groove once, thereby driving multiple material picking grippers to move back and forth once between the material picking station and multiple material unloading station.

[0025] 5. In the multi-station automatic processing equipment for pins provided by this invention, copper wire is fed into the cutting edge structure of the cutting block. The pressure block, driven by the push rod assembly, aligns with and presses the copper wire against the cutting edge structure, thus limiting and locking the copper wire at the cutting edge structure. The drive rod moves the cutting edge structure and pressure block forward, cutting the copper wire into a section of pin. Then, the pressure block, driven by the push rod assembly, separates from the cutting edge structure, releasing the copper wire from its locked position at the cutting edge structure. This allows the pressure block and cutting edge structure to switch from a pressed state to an open state, facilitating the removal of the pin by the material handling gripper from the cutting edge structure for subsequent processing and shaping. This completes the cutting operation of a section of pin. The pin cutting mechanism using this technical solution can quickly and effectively cut copper wire into several sections of pin, offering convenient and fast operation and high cutting speed. It can better meet the processing needs of large-volume pin production, thus improving production efficiency. Attached Figure Description

[0039] Example 1

[0040] This embodiment provides, as follows: Figure 1-7The diagram illustrates a multi-station automatic processing equipment for insert pins, comprising a cutting mechanism 1, a material handling mechanism 2, and an insert pin processing system mounted on a frame 8. The cutting mechanism 1 cuts incoming copper wire into copper insert pins to be processed. The material handling mechanism 2 has a movable material handling station located on one side of the cutting mechanism 1. The insert pin processing system includes multiple insert pin processing devices 4 arranged parallel to and spaced apart from the cutting mechanism 1, and a pushing device 3 arranged opposite to the multiple insert pin processing devices 4. Multiple material feeding stations are located on the moving path of the material handling mechanism 2 between the pushing device 3 and the multiple insert pin processing devices 4. The material handling mechanism 2 moves back and forth between the material handling station and multiple material handling stations to pick up the copper pin parts from the material handling station and feed them to the multiple material handling stations in sequence. The multiple pushing devices 3 move synchronously towards or away from the multiple pin processing devices 4, thereby pushing the copper pin parts at the multiple material handling stations into the multiple pin processing devices 4 respectively. The pin processing devices 4 push the processed copper pin parts back to the corresponding material handling station, where they can be picked up again by the material handling mechanism 2 and sent to the next station. The copper pin parts are formed into finished pins after the multiple pin processing devices 4 have completed the processing steps of rounding corners, punching grooves and punching bosses respectively.

[0041] In the above embodiment, the copper wire is first cut into pin copper parts to be processed by the cutting mechanism 1. Then, the pin copper parts are sequentially fed from the picking station to multiple unloading stations by the material picking mechanism 2. Each unloading station corresponds to a pin processing device 4. During the processing steps, the pin copper parts at the multiple unloading stations are pushed into the multiple pin processing devices 4 by the pushing device 3. The pin processing devices 4 will push the processed pin copper parts back to their respective unloading stations, and then be picked up by the picking mechanism 2 and sent to the next station. This process is repeated until all the processing steps of the pin are completed, so that each pin copper part will sequentially enter multiple pin processing stations. In device 4, the pins are formed after completing the rounding, groove punching, and boss punching processes. This automated processing equipment directly processes the cut pin copper parts through multiple pin processing devices to complete the rounding, groove punching, and boss punching. The coordination and connection between each process is reliable, realizing the entire production process of pins from raw material cutting, station feeding, and processing. It reduces the waiting time of each process, which helps to speed up the production rhythm and shorten the total production time. It makes the time to complete the production of a pin product shorter, improves production efficiency, and realizes automated processing operation throughout the entire process. This not only ensures product quality but also reduces labor costs and significantly improves the degree of automation in pin production.

[0042] In a preferred embodiment, a movable gap is formed between the pushing device 3 and the multiple pin processing devices 4. The picking mechanism 2 includes multiple picking grippers 21 spaced apart for gripping the copper pins. Multiple unloading stations are spaced apart in the movable gap according to the moving distance of the multiple picking grippers. The picking mechanism 2 drives the multiple picking grippers 21 to reciprocate along the length of the movable gap. The pushing device 3 includes a mounting base 31 disposed on one side of the movable gap and a station slider 32 movably disposed on the mounting base 31, and multiple push rod structures 33 spaced apart in multiple guide holes at one end of the station slider 32. These push rod structures 33 are opposite to the open ends of the multiple pin processing devices 4. Driven by the station slider 32, the push rod structure 33 pushes the copper pins in the multiple pick-up grippers 21 into the multiple pin processing devices 4. Each of the multiple pin processing devices has a push rod for pushing the copper pins out of their open ends. When the multiple pick-up grippers 21 move to the multiple unloading stations, the station slider 32 moves towards the side closer to the pin processing device and drives the multiple push rod structures 33 to push against the ends of the multiple copper pins, thereby pushing the multiple copper pins into the multiple pin processing devices. The multiple pin processing devices then process the copper pins in their respective positions. After processing, the copper pins are pushed out of the pin processing device 4 by the push rods and can be picked up by the returning pick-up grippers 21 and sent to the next station for processing. This structural design allows the push rod structure to accurately feed the copper pins from the pick-up gripper into the pin processing device, realizing the feeding and transfer of the copper pins between the pick-up gripper and the pin processing device. The design is reasonable and the cooperation is accurate and reliable.

[0043] The following is combined Figure 1-5 The specific configuration of the pin insertion processing device system is described in detail below:

[0044] The pin processing system includes a mold fixing plate 6 disposed on the other side of the movable gap. The plurality of pin processing devices 4 each include a primary rounding device 41, a secondary rounding device 42, and an integrated stamping device 43 arranged sequentially and at intervals on the mold fixing plate 6. The primary rounding device 41, the secondary rounding device 42, and the integrated stamping device 43 are respectively arranged opposite to the plurality of push rod structures 33. The primary rounding device and the secondary rounding device can use an R-type cutter or a file to perform rounding operations on the pin copper parts. The integrated stamping device uses a die to perform punching and punching operations on the pin copper parts. Since the rounded head of the copper pin is relatively rough after the initial rounding, a second rounding is required to achieve a smooth finish. The copper pin can undergo two processes, punching grooves and punching bosses, in the integrated stamping device 43. By optimizing the structural layout, the number of pin processing devices 4 can be reduced. In this structure, the copper pin is first fed into the primary rounding device 41 for initial pre-rounding, then into the secondary rounding device 42 for final rounding, and finally into the integrated stamping device 43 for punching grooves and punching bosses. Thus, the processing sequence of each pin is to go through the primary rounding device 41, the secondary rounding device 42, and the integrated stamping device 43 in sequence to finally become a finished pin. The finished pin will fall into the discharge port 81 under the gripping of the material handling chuck 21.

[0045] As a specific structural setting, such as Figure 5As shown, four material-picking grippers 21 are provided on the material-picking mechanism 2. Three material-discharging stations are respectively provided at the opening ends of the primary rounding device 41, the secondary rounding device 42, and the integrated stamping device 43. When the first material-picking gripper 21 is at the material-picking station, it is opposite to the cutting mechanism 1. When the other three material-picking grippers 21 are at the three material-discharging stations, they are respectively opposite to the primary rounding device 41, the secondary rounding device 42, and the integrated stamping device 43. The frame 8 is provided with a discharge port 81 located after the material-discharging station on the moving path of the material-picking mechanism 2. When the last material-picking gripper 21 moves back and forth, it drives the finished pin to reach above the discharge port 81. An ejector mold 5 is provided on the mold fixing plate 6 to push the finished pin into the discharge port 81. In this structural setup, the material picking station and three material dispensing stations are arranged alternately from left to right. The discharge port 81 is located after the multiple material dispensing stations. The four material picking grippers 21 move back and forth between the material picking station and the three material dispensing stations. The synchronous translation of the four material picking grippers 21 is equivalent to moving forward or backward by one station distance. That is, the first material picking gripper 21 moves from the material picking station to the first material dispensing station, and so on, moving forward one station at a time. After the pushing device 3 completes the pushing action, the four material picking grippers 21 will move backward one station at a time to reset. Thus, each cut pin copper part is transferred to the three material dispensing stations in sequence by the four material picking grippers 21 and completes the corresponding processing steps one after another. Finally, the last material picking gripper 21 moves the finished pin to the discharge port to realize the finished product discharge.

[0046] The following is combined Figure 3-5 The specific structure of the material handling mechanism is described in detail below:

[0047] The material handling mechanism 2 includes a sliding bar 22 that can be reciprocated on the mold fixing plate 6, and a plurality of material handling grippers 21 are arranged at intervals on the sliding bar and move with the sliding bar. The mold fixing plate 6 extends along the moving direction of the material handling mechanism 2 and is provided with a material handling groove 23 that allows the sliding bar 22 to move. To enable the sliding bar 22 to reciprocate in the material picking chute 23, a power assembly structure connecting the material picking mechanism 2, the cutting mechanism 1, and the pin insertion processing system is also installed on the frame 8. The power assembly structure provides driving force, and the material picking mechanism, the cutting mechanism, and the pin insertion processing system on the frame are all driven by the power assembly structure to perform their respective operations. The power assembly structure includes a power shaft 7 and a material picking drive cam 71 linked to the power shaft 7. One end of the sliding bar 22 is connected to the material picking drive cam 71 through a roller bearing, and a first spring 24 is provided between the other end of the sliding bar 22 and the material picking chute 23. Specifically, a limiting block is provided in the material picking chute 23 opposite to one end of the sliding bar 22, so that the two ends of the first spring 24 abut against the sliding bar 22 and the limiting block, respectively. This structural design utilizes the first spring 24 to apply an elastic force to the sliding bar to maintain contact with the material-picking drive cam 71. Since the sliding bar slides in contact with the outer periphery of the material-picking drive cam through a roller bearing, by reasonably designing the motion trajectory of the material-picking drive cam, one rotation of the drive cam drives the sliding bar to reciprocate once along the material-picking chute, thereby enabling multiple material-picking grippers to reciprocate once between the material-picking station and multiple material-discharging station.

[0048] The following combination Figure 1 , Figure 5-7 The specific structure of the cutting mechanism is described in detail below:

[0049] The copper wire is conveyed to the cutting mechanism 1 via the wire feeding mechanism 9. Figure 1(A represents copper wire). The cutting mechanism 1 includes a fixed base 11, a drive rod 12, a cutting block 13, a pressing block 14, and a top rod assembly 16. The fixed base 11 has guide grooves extending through both ends, and the drive rod 12 is reciprocally disposed in the guide grooves. The cutting block 13 is linked to the drive rod 12 and has a cutting edge structure 131 extending out of one end of the guide groove, allowing the copper wire to pass through the cutting edge structure 131 in a straight line. The pressing block 14... The pressure block 14 is pivotally positioned between the guide groove and the cutting block 13. It has a pressed state where it engages with the cutting edge structure 131 to press the copper wire, and an open state where it separates from the cutting edge structure 131 to release the copper wire. The drive rod 12 moves the cutting block 13 in the pressed state to cut the copper wire into a section of pin copper part. The push rod assembly 16 passes through the guide groove and connects to the pressure block 14, and is used to drive the pressure block to switch between the pressed state and the open state.

[0050] During the cutting operation of the copper wire by the cutting mechanism, the copper wire is fed into the cutting edge structure of the cutting block 13. Driven by the push rod assembly 16, the pressure block 14 aligns with and presses the copper wire against the cutting edge structure 13, thus limiting and locking the copper wire at the cutting edge structure. The drive rod 12 moves the cutting edge structure and pressure block forward, cutting the copper wire into a section of pin copper component. Then, driven by the push rod assembly 16, the pressure block 14 separates from the cutting edge structure, releasing the copper wire from the cutting edge structure. Position locking at 131 switches the pressure block 14 and the cutting edge structure 131 from the pressed state to the open state, so that the material handling gripper 21 can take the copper pin part from the cutting edge structure and send it to the pin processing device for subsequent processing and shaping. This completes the cutting operation of a pin section. The cutting mechanism using this technical solution can quickly and effectively cut copper wire into several sections of pin copper parts. It is convenient and fast to operate, and the cutting speed is fast. It can better meet the processing needs of processing equipment for a large number of pin products and is conducive to improving production efficiency.

[0051] As a specific structural setting, such as Figure 7As shown, the pressing block 14 includes a V-shaped pressing port that is vertically opposite to the blade structure 131. The V-shaped pressing port can better lock the copper wire onto the blade structure 131. A cutting drive cam 72 is linked to the power shaft 7. One end of the drive rod 12 is connected to the cutting drive cam 72, and a second spring (not shown in the figure) is provided between the other end and the guide groove. A stepped groove suitable for installing the cutting block 13 and the pressing block 14 is formed on the side of the drive rod 12. The pressing block 14 is movably disposed in the stepped groove via the shaft and connected to the top of the cutting block 13. The top of the cutting block 13 is formed with a beveled structure. With this structure, when the pressing block 14 is in the open state, it fits against the beveled structure and swings upward to separate from the blade structure. In addition, when the pressing block 14 is in the closed state, it separates from the beveled structure and swings downward to engage with the blade structure.

[0052] The following combination Figure 6 The specific configuration of the push rod assembly is described in detail as follows: The top of the fixed base 11 has two insertion holes 15 that connect to the guide groove. The push rod assembly 16 includes a first push rod 161 and a second push rod 162 that are respectively inserted into the two insertion holes 15 and contact the pressure block 14, and two sets of clamping lever structures 163 that drive the two push rods to press against the pressure block 14 in a staggered manner. Two clamping cams 73 are provided on the power shaft 7 to connect the two sets of clamping lever structures 163. By reasonably designing the movement trajectory of the two clamping cams 73, when the two clamping cams 73 rotate, they will drive the two sets of clamping lever structures 163 to rotate, thereby driving the first push rod 161 and the second push rod 162 to alternately press against the pressure block 14, thereby realizing that the pressure block 14 swings up and down relative to the cutting block 13, completing the operation process of pressing and releasing the copper wire at the cutting edge structure 131.

[0053] As can be seen from the above structure, when the first push rod 161 presses against the pressure block 14 under the drive of one of the sets of opening lever structures 163, the second lever does not apply pressure to the pressure block, so that the pressure block 14 and the blade structure 131 are engaged to achieve the function of pressing the copper wire; and when the second push rod 162 presses against the pressure block 14 under the drive of another set of opening lever structures 163, the first push rod 161 does not apply pressure to the pressure block, so that the pressure block 14 and the blade structure 131 are separated to achieve the function of releasing the copper wire, thereby realizing the switching of the pressure block between the pressed state and the open state, which helps to complete the cutting action of the copper wire.

[0054] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
