Description

Technical Field

[0001] This application relates to the field of heating tube processing, and in particular to a tube needle stamping device for heating tubes. Background Technology

[0002] Electric hot pots, electric grills, or electric cookers all use heating elements. The heating element extends from the heating structure of these products, forming a needle. The main function of the needle is to provide power to the heating element and to detect the temperature, that is, to detect the real-time temperature of the heating element by using the surface temperature of the needle.

[0003] When the tube pin is connected to the heating structure, the surface of the tube pin has threads, and the heating structure has a terminal pin. The main function of the terminal pin is to fix the heating tube in the heating structure using the tube pin. The terminal pin also has threads. After the terminal pin is screwed into the tube pin of the heating tube, it is easy to loosen under the influence of external force and can be screwed out again in the opposite direction of the threads, which will affect the use of subsequent products. Summary of the Invention

[0004] To address the aforementioned issues, this application provides a needle stamping device for heating tubes.

[0005] The needle stamping device for heating tubes provided in this application adopts the following technical solution:

[0006] A needle stamping device for a heating tube is used for installing a needle and a terminal pin of a heating tube, wherein the needle penetrates the terminal pin; the device includes a frame, a placement member, a stamping member, and an abutment member; the placement member is mounted on the frame and has a placement groove for placing the heating tube and the needle tube; the abutment member is mounted on the frame, the needle extends through the placement groove into the abutment member, and the terminal pin engages with the abutment member; the stamping member is mounted on the frame and is located above the abutment member; the stamping member drives a stamping end to stamp against the terminal pin, and the terminal pin is pressed against the needle by the stamping end and the abutment member.

[0007] By adopting the above technical solution, the heating tube is placed in the placement groove, and the placement groove is pushed towards the abutment, so that the terminal pin on the tube pin is pushed onto the abutment. When the stamping end of the stamping part presses down on the terminal pin, the stamping end and the abutment respectively clamp the terminal pin and apply a clamping force. The terminal pin is pressed against the tube pin by the clamping force, making it difficult for the terminal pin to loosen, thus ensuring the stability of the connection between the terminal pin and the tube pin.

[0008] Optionally, the abutment member has a first half-opening for placing the terminal pin, and the stamping end has a second half-opening; after the first half-opening and the second half-opening are closed, a complete closed opening is formed, and the inner diameter of the closed opening is smaller than the outer diameter of the terminal pin.

[0009] By adopting the above technical solution, the abutment is located in the first half of the opening. When the stamping end of the stamping part is stamped, the second half of the opening will abut against the upper surface of the terminal pin. During the stamping process, the first half of the opening and the second half of the opening close to form a complete closed opening, thereby fixing the stamping force of the stamping end of the stamping part on the terminal pin. At the same time, the first half of the opening and the second half of the opening can make the force on the terminal pin more even, ensuring that the terminal pin is pressed more stably and the clamping effect is better.

[0010] Optionally, the placement component is further provided with a plurality of adjustment slots; the frame is provided with a plurality of adjustment parts, the adjustment parts matching and corresponding one-to-one with the adjustment slots, so that the placement component slides along the frame through the adjustment slots and the adjustment parts.

[0011] By adopting the above technical solution, the placement component can use several adjustment parts and adjustment grooves to limit its own movement trajectory and fix it, so as to avoid the placement component from moving in a skewed position. At the same time, the placement component can be adapted to other heating tubes of different sizes, so as to ensure that when heating tubes of different sizes are placed on the placement component, the adjustment parts limit the placement component to push it towards the abutting component, so that the terminal pin on the tube pin can be inserted into the first half of the opening.

[0012] Optionally, the adjusting part includes a fixed end and a screwing end; the screwing end is screwed to the fixed end, and the screwing end abuts against the inner wall of the placement part.

[0013] By adopting the above technical solution, after the placement part can be moved to the required position along the moving path, the screw end is screwed to the fixed end, so that the screw end abuts against the inner wall of the placement part, and as it is continuously tightened, the screw part continuously presses the placement part downward, so that after the position of the placement part is adjusted, it is fixed by the pressure of the screw end and cannot slide at will, ensuring that the placement part will not be affected by pressure and shift during stamping.

[0014] Optionally, the placement component is further provided with fasteners; at least two fasteners are provided, and both are connected to the heating tube.

[0015] By adopting the above technical solution, the heating tube is fixed in the placement groove using fasteners, which avoids positional displacement caused by force during the connection between the tube pin and the terminal pin. The fasteners provide a stable fixation for the position of the heating tube.

[0016] Optionally, the fastener includes a hinge portion, an elastic portion, and a fastening portion; the fastening portion is movably connected to the placement component through the hinge portion; the fastening portion includes a fastening rod and a fastening frame; the fastening frame is provided with a telescopic groove, and the fastening rod is inserted into the telescopic groove and connected to the fastening frame; one end of the elastic portion is connected to the inner wall of the telescopic groove, and the other end is connected to the fastening rod.

[0017] By adopting the above technical solution, the heating tube is located behind the placement slot. Pulling the fastening bracket causes the elastic part of the fastening bracket to extend. Then, the fastening bracket and fastening rod are rotated above the placement part through the hinge part, and the fastening bracket is released. The fastening bracket is pulled down by the elastic force of the elastic part, so that the fastening bracket blocks the slot opening of the placement slot, thereby limiting the upward path of the heating tube.

[0018] Optionally, the frame is also provided with a sliding member at an angle; the placement member is slidably connected to the sliding member.

[0019] By adopting the above technical solution, the sliding member is used to move the placement member along the inclined path of the sliding member. During the movement along the surface of the inclined sliding member, the pins and terminal pins on the placement member move from high to low, so as not to hit the abutting member.

[0020] Optionally, the sliding member includes a guide portion, a mounting portion, and a reset portion; the guide portion is inclinedly disposed on the frame; the placement member is slidably connected to the guide portion; the mounting portion is mounted on one end of the guide portion near the abutment member; the reset portion has elasticity, and one end is connected to the mounting portion and the other end is connected to the placement member; the pressure of the placement member on the reset portion is less than the elasticity of the reset portion, and when the heating tube is placed in the placement groove, the pressure on the reset portion is greater than its own elasticity.

[0021] By adopting the above technical solution, when the heating tube is not placed in the placement slot, the reset part provides a spring force so that the placement part is located on the side of the guide part away from the abutment. When the heating tube is placed in the placement slot, the pressure exerted by the placement part and the heating tube on the reset part is greater than the spring force of the reset part, so that the placement part drives the heating tube to move along the guide part until the tube pin and terminal pin move to the abutment, thus eliminating the need to push the placement part to move along the guide part, improving the ease of use.

[0022] Optionally, the abutting member has a through-hole; the placing member has a through-part, and the through-part matches the through-hole.

[0023] By adopting the above technical solution, when the placement part moves along the sliding part or guide part to the abutting part, the through part on the placement part passes through the through opening of the abutting part, and the through part matches the through opening, thereby ensuring that the placement part moves along the sliding part or guide part without being misaligned.

[0024] Optionally, the stamping end is provided with a limiting part, which engages with the through part.

[0025] By adopting the above technical solution, when the stamping part drives the stamping end to move toward the terminal pin and the abutment, the through part passes through the through opening of the abutment, and the limiting part is stuck in the limiting groove by the limiting opening. After the through part is stuck, it cannot get out of the through opening, and the placement part cannot move freely along the sliding part, thereby fixing the position of the placement part and ensuring the stability of the stamping process.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. Place the heating tube in the placement slot and push the placement slot toward the abutment, so that the terminal pin on the tube pin is pushed onto the abutment. When the stamping end of the stamping part presses down on the terminal pin, the stamping end and the abutment respectively clamp the terminal pin and apply a clamping force. The terminal pin is clamped to the tube pin by the clamping force, making it difficult for the terminal pin to loosen and ensuring the stability of the connection between the terminal pin and the tube pin.

[0028] 2. The abutment is located inside the first half of the opening. When the stamping end of the stamping part is stamped, the second half of the opening will abut against the upper surface of the terminal pin. During the stamping process, the first half of the opening and the second half of the opening close to form a complete closed opening, thereby fixing the stamping force of the stamping end of the stamping part on the terminal pin. At the same time, the first half of the opening and the second half of the opening can make the force on the terminal pin more even, ensuring that the terminal pin is pressed more stably and the clamping effect is better.

[0029] 3. The placement component can be fixed by limiting its own movement trajectory using several adjustment parts and adjustment grooves to prevent the placement component from moving in a skewed position. At the same time, the placement component can be adapted to heating tubes of different sizes to ensure that when heating tubes of different sizes are placed on the placement component, the adjustment parts limit the placement component to push it towards the abutting part, so that the terminal pin on the tube pin can be inserted into the first half of the opening.

[0030] 4. Once the placement part can be moved to the desired position along the moving path, it is screwed together with the fixed end by the screwing end, so that the screwing end abuts against the inner wall of the placement part. As the screwing is continuously tightened, the screwing part continuously presses the placement part downward, so that the position of the placement part is fixed by the pressure of the screwing end after the adjustment is completed, and it cannot slide at will, ensuring that the placement part will not be displaced by the pressure during stamping.

[0047] The following is in conjunction with the appendix Figure 1 -Appendix Figure 10 This application will be described in further detail below.

[0048] This application discloses a needle stamping device for heating tubes.

[0049] A needle stamping device for heating tubes, reference Figure 1As shown, this device is used for installing the pin 2 and terminal pin 3 of the heating tube 1. The pin 2 passes through the terminal pin 3, allowing the terminal pin 3 to move to the end near the heating tube 1. Generally, the heating tube 1 is installed in a heating structure such as a heating rack, making it easy to install in electric ovens, electric ovens, electric cookers, etc. The main function of the terminal pin 3 is to fix the heating tube 1 in the heating structure using the pin 2. The terminal pin 3 can be made of high-temperature resistant rubber or plastic. The inner wall of the terminal pin 3 is also provided with internal threads, and the pin 2 is provided with external threads, so that the terminal pin 3 can be screwed into the pin 2 of the heating tube through the internal and external threads. However, after being screwed into the pin 2, the terminal pin 3 is still easily loosened by external forces and can be screwed out again in the opposite direction of the threads, affecting subsequent use. Therefore, this stamping device is needed to fix the terminal pin 3 to the pin 2.

[0050] refer to Figure 2 As shown, it includes a frame 4, a placement component 5, a stamping component 6, and a connecting component 7. The placement component 5 is installed on the frame 4, and the placement component 5 is provided with a placement groove for placing the heating tube 1 and the needle tube. The placement component 5 can be a placement frame. The placement groove in the placement frame is consistent with the style of the heating tube 1 or the heating frame, so that the heating tube 1 can be just embedded in the placement groove. At the same time, the placement groove is provided with a slot for the needle tube 2 to extend out. When the heating tube 1 is accurately embedded along the inner wall of the placement groove, the needle tube 2 extends out of the slot.

[0051] The abutment 7 is installed on the frame 4 and is on the same horizontal plane as the placement part 5. The tube pin 2 extends through the placement groove to the abutment 7. The terminal pin 3 is engaged with the abutment 7. The abutment 7 can be a metal abutment post or abutment frame. The metal material has pressure resistance, which can facilitate the stable pressure of the terminal pin 3 during stamping. When the heating tube 1 is placed in the placement groove, the tube pin 2 extends out of the groove and into the abutment 7, while the terminal pin 3 is located on the top of the abutment 7.

[0052] The stamping part 6 is installed on the frame 4 and located above the abutment part 7. The stamping part 6 can be a hydraulic cylinder. A stamping block can be set at the stamping end 61 of the hydraulic cylinder. The shape of the stamping block matches the size of the abutment part 7, so that when the stamping block is driven by the hydraulic cylinder, it can move towards the abutment part 7 and fit against the top of the abutment part 7. The stamping block is connected to a guide rod, which is fixedly installed on the frame 4. The stamping block is provided with a through hole that passes through the guide rod, so that the stamping block moves up and down along the guide rod during stamping. The guide rod is used to improve the accuracy of the stamping position of the stamping block.

[0053] Since the pin 2 passes through the abutment 7 and the terminal pin 3 is located on the top of the abutment 7, when the stamping end 61 is driven by the stamping end 61 to press against the terminal pin 3, the terminal pin 3 is clamped by the stamping end 61 and the abutment 7, so that the terminal pin 3 is pressed against the pin 2, ensuring that the connection between the terminal pin 3 and the pin 2 is stable and difficult to separate at will.

[0054] The stamping of the stamping part 6 can be either cold pressing or hot pressing. During cold pressing, the terminal pin 3 is directly pressed against the tube needle 2 by pressure. During hot pressing, an annular groove can be opened on the tube needle 2, and the terminal pin 3 is located on the annular groove. The stamping end 61 of the stamping part 6 is provided with a heating element, so that when the stamping end 61 of the stamping part 6 presses against the tube needle 2, the part of the terminal pin 3 located in the annular groove is softened by hot pressing. Then, the softened terminal pin 3 is pressed against the annular groove by the stamping effect. After the stamping end 61 separates from the abutment 7, the terminal pin 3 cools down, causing the part located in the annular groove to harden, so that it cannot be separated from the annular groove, thereby further achieving the effect of being stable and difficult to separate from the tube needle 2.

[0055] Further reference Figure 2 and Figure 3 As shown, the abutment 7 has a first half-opening 71 for placing the terminal pin 3, and the stamping end 61 of the stamping part 6 has a second half-opening 62. After the first half-opening 71 and the second half-opening 62 are closed, a complete closed opening is formed, and the inner diameter of the closed opening is smaller than the outer diameter of the terminal pin 3, so that when the heating tube 1 is placed in the placement groove, the heating tube 1 is pushed towards the abutment 7, so that the terminal pin 3 abuts in the first half-opening 71.

[0056] When the stamping end 61 of the stamping part 6 is stamped, the second half-opening 62 will abut against the upper surface of the terminal pin 3. During the stamping process, the first half-opening 71 and the second half-opening 62 close to form a complete closed opening, thereby fixing the stamping force of the stamping end 61 of the stamping part 6 on the terminal pin 3. At the same time, the first half-opening and the second half-opening 62 can make the force on the terminal pin 3 more even, ensuring that the terminal pin 3 is pressed more stably and the clamping effect is better.

[0057] Furthermore, refer to Figure 3 and Figure 4 As shown, the placement component 5 is also provided with several adjustment slots 51; the frame 4 is provided with several adjustment parts 41, which match and correspond one-to-one with the adjustment slots 51. The adjustment parts 41 can be adjustment columns or adjustment frames, and the size of the adjustment parts 41 is exactly the same as the opening of the adjustment slots 51, so that the placement component 5 slides along the frame 4 through the adjustment slots 51 and the adjustment parts 41. The adjustment parts 41 are used to limit the movement of the placement component 5 by passing through the adjustment slots 51, so that the placement component 5 can only move along the adjustment slots 51. The number of adjustment slots 51 is set to ensure the accuracy of the movement of the placement component 5. This embodiment takes two as an example.

[0058] Specifically, after the placement member 5 is inserted into the adjustment part 41 through the adjustment groove 51, the placement member 5 is pushed to slide towards the abutment member 7. At the same time, the movement trajectory of the placement member 5 is fixed by several adjustment parts 41 and adjustment groove 51 to prevent the movement position of the placement member 5 from being skewed, so that the tube pin 2 of the heating tube 1 placed in the placement groove cannot be inserted into the first half-joint 71. Meanwhile, the placement member 5 can be adapted to other heating tubes 1 of different sizes, so that when heating tubes 1 of different sizes are placed in the placement member 5, the adjustment part 41 limits the placement member 5 to push it towards the abutment member 7, so that the terminal pin 3 on the tube pin 2 can be inserted into the first half-joint 71.

[0059] Further, refer to Figure 4 As shown, the adjusting part 41 includes a fixed end 411 and a screw end 412; the screw end 412 is screwed to the fixed end 411 and abuts against the inner wall of the placement part 5. The screw end 412 can be a bolt, and the outer diameter of the end of the bolt away from the frame 4 is larger than the transverse diameter of the adjusting groove 51. The fixed end 411 can be a fixing post, and a threaded groove is provided on the top of the fixing post. The bolt can be screwed into the threaded groove. The outer diameter of the fixing post is exactly the same as the opening of the adjusting groove 51, or slightly smaller than the opening of the adjusting groove 51, so that the fixing post can move within the adjusting groove 51.

[0060] Specifically, when the position of the placement part 5 needs to be adjusted, the placement part 5 forms a fixed moving path with the adjustment groove 51 and the adjustment part 41. After the placement part 5 can move to the required position along the moving path, it is screwed to the fixed end 411 by the screw end 412, so that the screw end 412 abuts against the inner wall of the placement part 5. As it is continuously tightened, the screw part continuously presses the placement part 5 downward. Thus, after the position of the placement part 5 is adjusted, it is fixed by the pressure of the screw end 412 and cannot slide at will, ensuring that the placement part 5 will not be displaced by the pressure during stamping.

[0061] In some embodiments, reference Figure 5 As shown, the placement component 5 is also provided with fasteners 8; there are at least two fasteners 8, and both are connected to the heating tube 1. The fasteners 8 can be fastening clamps. The two fasteners 8 are located on both sides of the placement component 5. The fastening clamps are used to fix the heating tube 1 in the placement groove to prevent the heating tube 1 from tilting up due to uneven force when subjected to force.

[0062] When the fastener 8 uses a fastening clamp, a sliding groove is opened on the outer wall of the placement part 5. The sliding groove can be a T-shaped groove or an I-shaped groove or other irregular groove. The fastening clamp is provided with a sliding protrusion. The style of the sliding protrusion is consistent with the style of the sliding groove. If the sliding groove is a T-shaped groove, then the sliding protrusion is a T-shaped block. The fastening clamp is limited by the sliding groove and the sliding protrusion.

[0063] When the heating tube 1 is placed in the placement groove, the fastening clamp is moved along the sliding groove by the sliding protrusion, so that the fastening clamp moves above the placement groove, thereby blocking the lifting path of the heating tube 1 and preventing the tube pin 2 of the heating tube 1 from lifting when under pressure.

[0064] In another embodiment, reference Figure 6 As shown, in addition to using a fastening clamp, the fastener 8 may also include a hinge portion 81, an elastic portion 82, and a fastening portion 83. The fastening portion 83 is movably connected to the placement member 5 through the hinge portion 81. The fastening portion 83 may include a fastening rod 832 and a fastening frame 831. The fastening frame 831 is provided with a telescopic groove 833. The fastening rod 832 is inserted into the telescopic groove 833 and connected to the fastening frame 831. One end of the elastic portion 82 is connected to the inner wall of the telescopic groove 833, and the other end is connected to the fastening rod 832. The hinge portion 81 may be a hinge frame, which is installed on the outer wall of the placement member 5. The elastic portion 82 may be a spring, which is located in the telescopic groove 833 and has its two ends connected to the fastening rod 832 and the inner wall of the telescopic groove 833, respectively.

[0065] Specifically, after the heating tube 1 is placed in the slot, the fastening bracket 831 is pulled, causing the fastening bracket 831 to stretch the elastic part 82. Then, the fastening bracket 831 and the fastening rod 832 are rotated above the placement member 5 through the hinge part 81, and the fastening bracket 831 is released. The fastening bracket 831 is pulled down by the elastic force of the elastic part 82, so that the fastening bracket 831 blocks the slot opening of the placement slot, thereby limiting the upward path of the heating tube 1.

[0066] The fastening part 83 may also be provided with a pressing protrusion, which can press the heating tube 1, further providing the function of stabilizing the position of the heating tube 1.

[0067] In some embodiments, reference Figure 7 As shown, after the position of the placement component 5 is fixed, when the heating tube 1 is placed in the placement groove, it is pushed directly along the placement groove towards the abutment component 7. The tube pin 2 has a terminal pin 3 through it, so the terminal pin 3 will hit the side wall of the abutment component 7 and cannot be placed on the abutment component 7. It is necessary to manually lift it and place the terminal pin 3 on the top of the abutment component 7, which makes the use of the equipment inconvenient. Therefore, the frame 4 is also provided with a sliding component 9 at an angle.

[0068] The placement member 5 is slidably connected to the sliding member 9. The sliding member 9 is used to move the placement member 5 along the inclined path of the sliding member 9. During the movement along the surface of the inclined sliding member 9, the tube pin 2 and terminal pin 3 on the placement member 5 move from high to low, so that they do not hit the abutting member 7.

[0069] Furthermore, the sliding member 9 may include a guide part 91, a mounting part 92, and a reset part 93; the guide part 91 is inclinedly disposed on the frame 4, and the guide part 91 may be a guide rail. The guide rail is inclined in such a way that the end closer to the abutment 7 is lower than the end farther away from the abutment 7, and the tilt angle is determined according to the requirements, and needs to be greater than 30 degrees and less than 70 degrees.

[0070] The placement component 5 is slidably connected to the guide part 91. A placement slider 52 can be provided at the bottom of the placement component 5, and the placement slider 52 can slide along the guide rail.

[0071] The mounting part 92 is installed at one end of the guide part 91 near the abutment 7. The mounting part 92 can be a mounting post or a mounting plate. When the mounting part 92 is installed on the inclined guide part 91, the mounting part 92 is also inclined.

[0072] The reset part 93 can be a reset spring. The reset spring has a certain rebound force and one end is connected to the mounting part 92, and the other end is connected to the placement member 5. Since the mounting part 92 is fixed in position, the reset part 93 applies a certain elastic force to the placement member 5, and at the same time, the placement member 5 also applies a certain pressure to the reset part 93.

[0073] The pressure of the placement member 5 on the reset part 93 is less than the elastic force of the reset part 93, so that the reset part 93 can push the placement member 5 towards the guide part 91 away from the abutment member 7. When the heating tube 1 is placed in the placement groove, the combined weight of the heating tube 1 and the placement member 5 will exert greater pressure on the reset member. At this time, the pressure on the reset part 93 will be greater than its own elastic force. Therefore, the reset part 93 will be squeezed and will not be able to push the placement member 5. The placement member 5 will move along the guide part 91 towards the abutment member 7.

[0074] Specifically, when the heating tube 1 is not placed in the placement slot, the reset part 93 provides a spring force so that the placement member 5 is located on the side of the guide part 91 away from the abutment member 7. When the heating tube 1 is placed in the placement slot, the pressure exerted by the placement member 5 and the heating tube 1 on the reset part 93 is greater than the spring force of the reset part 93, so that the placement member 5 drives the heating tube 1 to move along the guide part 91 by itself until the tube pin 2 and the terminal pin 3 move onto the abutment member 7 (or the terminal pin 3 moves into the first half-joint 71), so that the placement member 5 no longer needs to be pushed to move along the guide part 91, thus improving the ease of use.

[0075] In some embodiments, reference Figure 8 and Figure 9 As shown, the abutting member 7 has a through-hole 72; the placing member 5 has a through-hole 53, and the through-hole 53 matches the through-hole 72. The through-hole 53 can be a through-hole plate or a through-hole block. The through-hole 72 is opened along the middle of the abutting member 7 and is opened vertically downward.

[0076] When the placement member 5 moves along the sliding member 9 or the guide 91 to the abutting member 7, the through part 53 on the placement member 5 passes through the through opening 72 of the abutting member 7. The through part 53 matches the through opening 72, that is, the size of the through part 53 is consistent with the inner diameter of the through opening 72, thereby ensuring that the placement member 5 moves along the sliding member 9 or the guide 91 without being tilted. Since the through opening 72 is opened vertically downward, the through part 53 is not interfered with by the vertical direction during the movement.

[0077] Among them, the stamping end 61 of the stamping part 6 is provided with a limiting part 63, which is engaged with the through part 53. The limiting part 63 can be a limiting frame, with a limiting opening in the middle of the limiting frame, and limiting grooves 531 on both sides of the through part 53. The thickness between the two limiting grooves 531 is the opening width of the limiting opening.

[0078] When the stamping part 6 drives the stamping end 61 to move toward the terminal pin 3 and the abutment 7, the through part 53 passes through the through opening 72 of the abutment 7, so that the position of the two limiting grooves 531 is located at the end away from the placement part 5. When the stamping end 61 stamps the terminal pin 3, the limiting part 63 is stuck in the limiting groove 531 by the limiting opening. After the through part 53 is stuck, it cannot get out of the through opening 72, and the placement part 5 cannot move freely along the sliding part 9, thereby fixing the position of the placement part 5 and ensuring the stability of the stamping process.

[0079] In another embodiment, reference Figure 10 As shown, the limiting part 63 can be a limiting post, and the shape of the limiting post is not limited. In this embodiment, a rectangular post is used as an example. A fixing opening 532 is opened on the through part 53. The fixing opening 532 is consistent with the shape of the limiting part 63. When the limiting part 63 descends together with the stamping end 61, the through part 53 passes through the fixing opening 532, and the same effect can be achieved.

[0080] Further reference Figure 8 As shown, the connection between the through part 53 and the placement member 5 can be a screw connection, that is, the through part 53 is provided with a screw, and the placement member 5 is provided with a screw hole. The depth of the screw screw into the screw hole is used to adjust the extension length of the through part 53, so that the through part 53 can be adjusted when adapting to heating tubes 1 of different sizes, and the limiting groove 531 can be accurately located on the other side of the through opening 72.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
