Description

Technical Field

[0001] This invention relates to the field of transformer technology, and more specifically, to a transformer for lighting devices and its processing equipment. Background Technology

[0002] A transformer is an electrical device that uses the principle of electromagnetic induction to change the voltage of alternating current. In various lighting systems, small transformers are used in lighting fixtures for voltage matching and constant current / constant voltage power supply. These transformers can be integrated inside the lighting fixture. For small lamps, the transformers used are relatively small in size and are usually directly integrated into the internal circuit board of the lighting fixture, with pins soldered to the circuit board to form a fixed connection.

[0003] However, for some large lighting installations, the required transformers are also relatively large. Since the core of a transformer is composed of metal coils and an iron core, its overall weight is relatively large. In actual use, the connection strength formed by fixing the pins to the circuit board is relatively poor. Especially for some lighting installations that need to be moved frequently (such as portable lighting fixtures or lighting fixtures on large engineering machinery), swaying will occur during actual use. At this time, the transformer itself will also sway accordingly. Due to the large weight and inertia of the transformer itself, it is easy to cause damage to the connection between the pins and the circuit board. In severe cases, it can lead to pin electrical connection failure, resulting in damage to the transformer and the circuit board. Summary of the Invention

[0004] The present invention provides a transformer for lighting devices and its processing equipment. The problem to be solved is that the transformer in the existing mobile large lighting devices is prone to shaking, which causes damage to the connection between the pins and the circuit board. In severe cases, it can lead to pin electrical connection failure, resulting in damage to the transformer and the circuit board.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a transformer for a lighting device, comprising a transformer body and a transformer base. The transformer body is composed of an insulating frame, a coil structure, an iron core structure, and pins. The pins are integrated at the bottom of the insulating frame. An installation structure is provided on the transformer base. A fixed docking structure is provided between the insulating frame and the transformer base.

[0006] The transformer base has pin sockets at the corresponding pin positions, and the pin sockets contain pin electrical contacts. The transformer base also has wiring sockets at the corresponding pin socket positions, and the wiring sockets contain wiring electrical contacts. The pin electrical contacts and wiring electrical contacts are electrically connected.

[0007] Preferably, the pin electrical contact is a metal cylindrical structure, which includes a spring-loaded contact part and a tight contact part. The inner diameter of the spring-loaded contact part is larger than the diameter of the pin. Multiple sets of elastic contact pieces are provided inside the spring-loaded contact part. The elastic contact pieces are fixedly connected to the pin electrical contact and have an elastic force that deforms toward the center of the pin electrical contact. The tight contact part is recessed.

[0008] A processing device for a transformer for a lighting device includes a gripping component, a first conveyor and a second conveyor. The first conveyor is used to transport the transformer body, and the second conveyor is used to transport the transformer base. The gripping component is set at the assembly station and its movement is controlled by an assembly driver. The gripping component is used to pick up and put down the transformer body.

[0009] Preferably, the gripping assembly includes a gripping frame, with clamping blocks and straightening blocks arranged below the gripping frame. Two sets of clamping blocks and two sets of straightening blocks are provided, and the two sets of clamping blocks and two sets of straightening blocks are symmetrically arranged in the areas on both sides of the gripping frame. Both clamping blocks and straightening blocks have the ability to move towards the center of the gripping frame. The clamping blocks are used to contact the transformer body and clamp the transformer body. V-shaped grooves are provided on the straightening blocks at the positions corresponding to each pin, and straightening components are installed in the V-shaped grooves.

[0010] Preferably, the straightening assembly consists of a wrap-around elastomer and a pushing assembly disposed in the straightening clamp. The wrap-around elastomer includes an arc-shaped fixing part, the curvature of which is adapted to the outer circumference of the pin. Multiple elastic plates are disposed on both sides of the arc-shaped fixing part, and the elastic plates on both sides of the arc-shaped fixing part are staggered. The stiffness coefficient of the elastic plates on both sides of the arc-shaped fixing part gradually increases from top to bottom. The arc-shaped fixing part is fixedly installed inside the V-shaped groove. When the elastic plates on both sides of the arc-shaped fixing part are extended, they fit against the inner walls of both sides of the V-shaped groove. The pushing assembly is used to push the elastic plates and cause the elastic plates to deform and bend in the opposite direction.

[0011] Preferably, the pushing assembly includes an arc-shaped pushing block. An arc-shaped guide groove is provided inside the straightening clamp block at the position corresponding to each elastic piece. The arc-shaped pushing block is slidably installed in the straightening clamp block and forms a piston structure. A flow channel is also provided inside the straightening clamp block, which is connected to each straightening clamp block. An air supply connector pipe is also connected to the straightening clamp block, which is connected to the flow channel and connected to an air supply device.

[0012] Preferably, an internal part is fixedly connected to the arc-shaped fixing part, the internal part is fixedly disposed inside the straightening clamp block, and a heating structure is installed inside the internal part.

[0013] Preferably, the gas supply equipment includes a heat source gas supply group and a cold source gas supply group, and the gas supply connector pipe is connected to the heat source gas supply group and the cold source gas supply group through a reversing valve. The straightening clamp is also equipped with a gas exchange outlet pipe, which is also connected to the flow channel. A pressure control valve is installed on the gas exchange outlet pipe.

[0014] Preferably, a gap is provided between the arc-shaped push block and the arc-shaped guide groove, and a cold-shrink seal is installed on the arc-shaped push block. The cold-shrink seal is composed of a storage bladder, which is sleeved on the arc-shaped push block and filled with a cold-shrink filler.

[0015] Preferably, the first conveyor is provided with a main body fixture for supporting and fixing the transformer body, and the second conveyor is provided with a base fixture for fixing the transformer base. The assembly drive includes a lifting drive and a lateral drive. The gripper is installed at the output end of the lateral drive, and the lateral drive is installed at the output end of the lifting drive. The lifting drive is used to drive the gripper assembly to move up and down, and the lateral drive is used to drive the gripper assembly to move laterally.

[0016] Preferably, the gripper is provided with two sets of grippers, with clamping blocks and straightening blocks both located inside the grippers. A clamping driver is installed on the gripper to control the movement of the grippers toward or away from each other. The straightening block is fixedly installed at the bottom of the grippers. A guide post is fixedly installed on the clamping block, which passes through the gripper and slides with it. A pre-tightening elastic element is provided between the clamping block and the grippers to provide a spring force to the clamping block away from the grippers.

[0017] The beneficial effects of this invention are as follows:

[0018] This invention allows the transformer to be installed independently in the corresponding equipment, ensuring that the transformer has sufficient stability when the equipment is moving or vibrating, and that it will not interfere with the circuit board, making it less likely to cause failure of the transformer's electrical connection, thus improving the safety of transformer use.

[0019] The transformer body of this invention can be directly modified from existing transformer products, for example, by adding a fixed docking structure to the full-load insulation frame. The overall improvement cost is low. Moreover, if the transformer body is damaged naturally during subsequent use, a new transformer body can be replaced by disassembling and assembling the transformer body and the transformer base, without replacing the entire circuit board. This makes maintenance convenient and reduces maintenance costs.

[0020] In the process of manufacturing a transformer, this invention pushes the elastic sheet and causes it to deform and bend in the opposite direction. This causes the elastic sheets on both sides of the arc-shaped fixing part to deform and move closer together until they cross, ultimately wrapping around the pin. The bent pin is then gradually pushed towards the arc-shaped fixing part, thus forming a straightening operation that wraps around the pin. During this operation, the pin is not stretched or scratched. The entire process is relatively gentle and can effectively protect the pin, especially from damage to the plating on the pin surface. This effectively ensures the assembly quality of the transformer body and the transformer base. Attached Figure Description

Detailed Implementation

[0037] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0038] Refer to the instruction manual appendix Figure 1 and Figure 2 A transformer for a lighting device includes a transformer body 1 and a transformer base 2. The transformer body 1 has the same structure as a conventional small transformer (or electronic transformer), for example, it consists of an insulating frame 11, a coil structure 12, an iron core structure 13 and pins 14. The coil structure 12 is wound around the outside of the insulating frame 11. The iron core structure 13 has a structure that extends into the interior of the insulating frame 11, thus forming the main part of the transformer structure. The pins 14 are integrated at the bottom of the insulating frame 11.

[0039] The transformer base 2 is provided with pin sockets 21 at the positions corresponding to pins 14. The pin sockets 21 are provided with pin electrical contacts 23 inside. The transformer base 2 is also provided with wiring sockets 22 at the positions corresponding to each pin socket 21. The wiring sockets 22 are used to connect external connection wires. The wiring sockets 22 are provided with wiring electrical contacts 221 inside. The pin electrical contacts 23 are electrically connected to the wiring electrical contacts 221.

[0040] The transformer base 2 is provided with mounting structures for docking with other structures, such as mounting holes for direct connection with the housing of the lighting device or the housing of external equipment. The insulating frame 11 is also provided with a fixing docking structure 15 for fixed connection with the transformer base 2, such as screw connection holes. After the transformer body 1 and the transformer base 2 are assembled, a new complete transformer is formed. In actual use, the transformer base 2 can be directly fixedly installed on the supporting structure such as the housing of the lighting device to form a direct fixed connection to the transformer. Corresponding connecting wires can be provided on the circuit board. By inserting the connecting wires into the wiring socket 22 and contacting the wiring electrical contact 221, an electrical connection with the corresponding pin 14 can be formed.

[0041] By adopting the above solution, the transformer can be installed independently in the corresponding equipment, ensuring that the transformer has sufficient stability when the equipment is moving or vibrating. It will not interfere with the circuit board, making it less likely to cause failure of the transformer's electrical connection and improving the safety of transformer use. At the same time, in the above solution, the transformer body 1 can be directly used with existing transformer products with simple modifications, such as adding a fixed docking structure 15 to the full-load insulation frame 11. The overall modification cost is low. Moreover, if the transformer body 1 is damaged naturally during subsequent use, a new transformer body 1 can be replaced by disassembling and assembling the transformer body 1 and the transformer base 2, without replacing the entire circuit board. This makes maintenance convenient and reduces maintenance costs.

[0042] In addition, please refer to the appendix to the instruction manual. Figure 2 and Figure 3The lead electrical contact 23 is a metal cylindrical structure, including a spring-loaded contact portion 231 and a tight contact portion 232. The inner diameter of the spring-loaded contact portion 231 is larger than the diameter of the lead 14, and multiple sets of elastic contact pieces 2311 are disposed within the spring-loaded contact portion 231. The elastic contact pieces 2311 are fixedly connected to the lead electrical contact 23 and have an elastic force that deforms towards the center of the lead electrical contact 23. The tight contact portion 232 is recessed, meaning its diameter is slightly smaller than the diameter of the lead 14. When the lead 14... When inserted into the pin electrical contact 23, each elastic contact piece 2311 forms sufficient elastic contact with the pin 14 and forms a multi-point connection. After the bottom end of the pin 14 is inserted into the tight contact part 232, an interference fit is formed, thus forming an electrical connection method in which elastic contact and tight contact coexist. Even if the lead wire shakes during subsequent use, it can ensure that the pin electrical contact 23 can form effective contact with the pin 14, avoid accidental phenomena, and further improve the safety of transformer use.

[0043] It should be noted that, in addition to the transformer body 1 adopting the existing conventional transformer structure, the wiring socket 22 used is also a commonly used wiring socket structure in electrical equipment, such as pressure plate type terminal block or spring type terminal block. Both of these wiring structures are commonly used in the field of electrical equipment, which are easy to disassemble and reuse. Therefore, this embodiment will not be explained in detail.

[0044] In the aforementioned transformer, to ensure effective electrical connection between the pin contact 23 and the pin 14, the elastic contact 2311 needs to have sufficient elasticity. Therefore, during the process of inserting the pin 14 into the pin socket 21, when the bottom end of the pin 14 contacts the elastic contact 2311, it will be subjected to a certain reverse resistance force. Since the pin 14 is mostly made of copper or other metals with high conductivity and low hardness, the pin 14 will inevitably be bent during the production and transportation of the transformer body 1. If the pin 14 is bent, during the assembly of the transformer body 1 and the transformer base 2, the bottom end of the bent pin 14 is likely to deviate from the pin socket 21, or after entering the pin socket 21, it is likely to come into contact with the side wall of the elastic contact 231 and form aggression with the connection between the elastic contact 2311 and the elastic contact 231. This results in the elastic contact 2311 being unable to be compressed, and the pin 14 being unable to be smoothly and completely inserted into the pin contact 23, thereby affecting the production efficiency and finished product quality of the aforementioned transformer.

[0045] Refer to the instruction manual appendix Figure 4 and Figure 5To address the aforementioned problems, this invention also provides a processing device for a transformer used in lighting devices, comprising a gripping assembly 3, a first conveyor 4, and a second conveyor 5. The first conveyor 4 is used to transport the transformer body 1, and the second conveyor 5 is used to transport the transformer base 2. The first conveyor 4 and the second conveyor 5 can employ conventional product conveying structures, such as chain conveyors or plate conveyors, which will not be discussed in detail in this embodiment. The first conveyor 4 is equipped with a main body fixture 41 for supporting and fixing the transformer body 1, and the second conveyor 5 is also equipped with a base fixture 51 for fixing the transformer base 2. Both the main body fixture 41 and the base fixture 51 are fixture structures designed to accommodate the corresponding support structure shapes, and the design of the fixture structures is also conventional. If necessary, additional fixing can be achieved using structures such as vacuum adsorption. These are all commonly used solutions and structures in industrial production, therefore, they will not be discussed in detail in this embodiment.

[0046] An assembly station is provided on the conveying path of the first conveyor 4 and the second conveyor 5. The gripping component 3 is set at the assembly station. The gripping component 3 is controlled to move by the assembly driver 6. The gripping component 3 is used to pick up and put down the transformer body 1. The assembly driver 6 controls the movement of the gripping component 3 so that the transformer body 1 moves above the transformer base 2 and assembles the transformer body 1 on the transformer base 2.

[0047] Specifically, the assembly driver 6 includes a lifting driver 61 and a lateral driver 62, and the gripping component 3 includes a gripping frame 31. The gripping frame 31 is installed at the output end of the lateral driver 62, and the lateral driver 62 is installed at the output end of the lifting driver 61. The lifting driver 61 is used to drive the gripping component 3 to move up and down, and the lateral driver 62 is used to drive the gripping component 3 to move laterally, that is, to control the gripping component 3 to move between the first conveyor 4 and the second conveyor 5. The lifting driver 61 and the lateral driver 62 can be mobile drive devices commonly used in industrial production, such as cylinders, motor screw structures and other automatic mobile control devices.

[0048] Among them, refer to the appendix of the instruction manual Figure 6Below the gripping frame 31, there are clamping blocks 32 and straightening blocks 33, with two sets of each. The two sets of clamping blocks 32 and two sets of straightening blocks 33 are symmetrically arranged on both sides of the gripping frame 31. Both clamping blocks 32 and straightening blocks 33 have the ability to move towards the center of the gripping frame 31. The clamping blocks 32 are used to contact the transformer body 1 and clamp it. The straightening blocks 33 have V-shaped grooves at positions corresponding to each pin 14. 331. A straightening component is installed in the V-groove 331. When the clamping block 32 contacts and clamps the transformer body 1, the straightening block 33 moves closer to the pin 14, so that the pin 14 gradually enters the V-groove 331. After the straightening component straightens the pin 14, the straightening block 33 can be controlled to leave the pin 14, and the clamping block 32 clamps the transformer body 1, so that it moves with the gripping component 3. After reaching the second conveyor 5, it docks with the corresponding transformer base 2 on the base fixture 51.

[0049] In the above embodiments, the movement drive of the clamping block 32 and the straightening block 33 can be driven by an independent movement drive (e.g., a cylinder) or by a single drive device. For example, the gripper frame 31 is provided with two sets of grippers 311, and the clamping blocks 32 and straightening blocks 33 on both sides of the gripper frame 31 are all located inside the grippers 311. The gripper frame 31 is also equipped with a clamping drive 312, which is used to control the movement of the grippers 311 towards or away from each other. The clamping drive 312 can be a dual-output cylinder or two opposing cylinders. The structure allows for synchronous movement of the two sets of grippers 311. The straightening block 33 can be directly fixedly installed on the inner side of the bottom end of the grippers 311. The clamping block 32 can slide with the grippers 311. For example, a guide post 321 is fixedly installed on the clamping block 32, passing through the grippers 311 and slidingly engaging with them. A pre-tightening elastic element 322 is provided between the clamping block 32 and the grippers 311. The pre-tightening elastic element 322 provides a spring force to the clamping block 32 away from the grippers 311. In actual use, when it is necessary to clamp the transformer body 1, refer to the attached instruction manual. Figure 7 The two grippers 311 are controlled to move closer together, so that the clamping block 32 makes pre-contact with the transformer body 1, thus pre-clamping the transformer body 1. Then, the transformer body 1 is lifted, and the grippers 311 are controlled to continue moving inward, so that the straightening block 33 moves closer to the pin 14 and the pin 14 enters the V-groove 331, where the straightening component performs straightening. After the transformer body 1 reaches above the second conveyor 5, the gripping component 3 is controlled to move the transformer body 1 downward. Refer to the attached instruction manual. Figure 8The transformer body 1 is gradually brought closer to the transformer base 2. At this point, straightening is complete. The gripper 311 can be controlled to move outward a certain distance first, so that the straightening clamp 33 leaves the pin 14 first, avoiding interference with the insertion of the pin 14 into the pin socket 21. At this time, the clamping clamp 32 still clamps the transformer body 1 under the action of elasticity (or a pressure structure that contacts the top of the transformer body 1 can be set at the bottom of the gripper 31). At this time, the transformer body 1 can be controlled to continue to move downward, so that the pin 14 is fully inserted into the pin socket 21, completing the assembly and processing of the transformer body 1 and the transformer base 2.

[0050] Furthermore, since a fixed docking structure 15 is provided between the transformer body 1 and the transformer base 2, and the fixed docking structure 15 can be a screw connection structure, after the transformer body 1 and the transformer base 2 are assembled, the second conveyor 5 continues to transport them. Moreover, other processing devices such as automatic screw-attaching equipment can be set at the subsequent position of the second conveyor 5 to fully assemble the transformer body 1 and the second conveyor 5. The above-mentioned equipment are all conventional devices in industrial production, and will not be explained in detail in this embodiment.

[0051] Refer to the instruction manual appendix Figure 9 and Figure 10 The aforementioned straightening assembly consists of a wrap-around elastic body 7 (mainly an elastic metal structure) and a pushing assembly 8 disposed in the straightening clamp 33, wherein, refer to the appendix of the instruction manual. Figure 11 The encapsulated elastomer 7 includes an arc-shaped fixing part 71, the curvature of which is adapted to the outer circumference of the pin 14. Multiple elastic pieces 72 are provided on both sides of the arc-shaped fixing part 71, and these pieces are staggered. The arc-shaped fixing part 71 is fixedly installed inside the V-groove 331. When extended, the elastic pieces 72 on both sides of the arc-shaped fixing part 71 conform to the inner walls of the V-groove 331. The pushing assembly 8 is used to push the elastic pieces 72 and cause them to deform and bend in the opposite direction. For details, please refer to the appendix of the instruction manual. Figure 10 When pin 14 enters the V-groove 331 and fits against the arc-shaped fixing part 71, the elastic sheet 72 can be pushed by the pushing component 8, so that the elastic sheets 72 on both sides of the arc-shaped fixing part 71 move closer to each other and deform until they cross, ultimately forming a wrap around pin 14. During the deformation of the elastic sheet 72, the bent pin 14 can be gradually pushed towards the arc-shaped fixing part 71, thereby forming a wrap-around straightening operation for pin 14. During this operation, pin 14 will not be stretched or scratched. The whole process is relatively gentle and can effectively protect pin 14, especially avoiding damage to the plating on the surface of pin 14, effectively ensuring the assembly quality of transformer body 1 and transformer base 2.

[0052] The jacking assembly 8 can be an existing small jacking structure, or it can be customized according to requirements, for example, as shown in the attached instruction manual. Figure 9 and Figure 10 The pushing assembly 8 includes an arc-shaped pushing block 81. Arc-shaped guide grooves 333 are provided inside the straightening clamp 33 at the positions corresponding to the elastic plates 72. The arc-shaped pushing block 81 is slidably installed in the straightening clamp 33, thus forming a piston structure. A flow channel 334 is also provided inside the straightening clamp 33, communicating with each straightening clamp 33. An air supply connector pipe 332 is also connected to the straightening clamp 33, communicating with the flow channel 334. The air supply connector pipe 332 is connected to an air supply device, such as an air pump. When air is supplied to the flow channel 334, the arc-shaped pushing block 81 is automatically pushed outward. Since the elastic plates 72 on both sides of the arc-shaped fixing part 71 are staggered, the corresponding arc-shaped guide grooves 333 can also be staggered. (Refer to the attached instruction manual.) Figure 12 This ensures that each arc-shaped push block 81 is independent and will not affect each other.

[0053] In addition, to reduce the springback of pin 14 and the stress concentration of pin 14 after straightening, this embodiment also provides the following improvement scheme for the straightening assembly, as shown in the appendix to the specification. Figure 14 and Figure 15 An internal part 73 is fixedly connected to the arc-shaped fixing part 71. The internal part 73 is fixedly installed inside the straightening clamp block 33. A heating structure 74, such as a heating resistor, is installed inside the internal part 73. In actual use, the encapsulated elastomer 7 can be heated, thereby heating the pin 14, so that the pin 14 can produce straightening deformation at a higher temperature, making the pin 14 easier to straighten. After straightening, stress concentration can be effectively reduced.

[0054] Furthermore, the gas supply equipment connected to the gas supply connector pipe 332 includes a heat source gas supply group and a cold source gas supply group. The gas supply connector pipe 332 is connected to the heat source gas supply group and the cold source gas supply group through a reversing valve. The heat source gas supply group consists of an air pump and hot gas, which can be air heated by a heating device. The cold source gas supply group consists of an air pump and cold gas, which can be low-temperature air after refrigeration processing or liquid nitrogen can be used directly. The straightening clamp block 33 is also equipped with a gas exchange outlet pipe 335, which is also connected to the guide channel 334. A pressure control valve is installed on the gas exchange outlet pipe 335.

[0055] Specifically, initially, high-temperature gas can be introduced into the flow channel 334 to assist in heating the pin 14. After the pin 14 is completely straightened, the heating structure 74 can be turned off, and low-temperature gas can be continuously introduced into the flow channel 334 through the cold source gas supply group. The original high-temperature gas is discharged through the gas outlet pipe 335, thereby reducing the overall temperature of the straightening clamp 33 and also reducing the temperature of the pin 14. If necessary, the pin 14 can be controlled to be lowered to below room temperature, causing the pin 14 to shrink and deform. This allows the pin 14 to expand when it is inserted into the pin electrical contact 23 and returns to room temperature, thereby improving its electrical contact effect with the pin electrical contact 23.

[0056] In addition, a gap is provided between the arc-shaped push block 81 and the arc-shaped guide groove 333. A cold-shrink seal 82 is installed on the arc-shaped push block 81. The cold-shrink seal 82 contacts the arc-shaped guide groove 333 at room temperature and forms a seal, thereby making the arc-shaped push block 81 form a complete piston structure. When the flow channel 334 is filled with low-temperature gas, the overall temperature of the straightening clamp block 33 decreases. The cold-shrink seal 82 has the ability to shrink when cooled. After cooling, the cold-shrink seal 82 also shrinks, and air leakage occurs at the arc-shaped guide groove 333. This allows the low-temperature gas to leak into the area of ​​the V-shaped groove 331, thereby improving the cooling effect on the pin 14.

[0057] Among them, refer to the appendix of the instruction manual Figure 15 The cold-shrink seal 82 is composed of a storage bladder 821, which is fitted onto the arc-shaped push block 81. The storage bladder 821 is filled with a cold-shrink filler 822, such as ethanol or mercury. When the temperature decreases, the liquid shrinks, and the storage bladder 821 shrinks accordingly. When the temperature returns to normal or even rises, the cold-shrink filler 822 expands, causing the storage bladder 821 to expand as well. This allows the storage bladder 821 to come into close contact with the inner wall of the arc-shaped guide groove 333, forming an effective seal.

[0058] It should be noted that the aforementioned arc-shaped fixing part 71 can also be improved accordingly. For example, the elastic sheets 72 on both sides of the arc-shaped fixing part 71 can be configured with a gradually increasing stiffness coefficient from top to bottom. That is, from top to bottom, the deformation difficulty of each elastic sheet 72 gradually increases. Consequently, under the same pressure, the upper elastic sheet 72 is more likely to bend and deform, thus forming a gradually wrapping shape from top to bottom, making the straightening work of the pin 14 more gentle. The thickness of the elastic sheets 72 on both sides of the arc-shaped fixing part 71 can be gradually increased from top to bottom. For details, please refer to the appendix of the instruction manual. Figure 13 With the same material, the thickness gradually increases, making it less prone to deformation.

[0059] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
