Description

Technical Field

[0001] This utility model relates to the field of outdoor gas stove technology, specifically to a rotating structure for a folding stove and a folding stove. Background Technology

[0002] To enrich outdoor life and facilitate food cooking and processing, outdoor stoves that are easy to operate and use are needed for outdoor activities. To this end, a portable, foldable gas stove that can be stored in a casing has been developed. This structure includes a casing, a base, and a connecting seat. A burner head bracket and a gas duct are fixed to the connecting seat. The burner head bracket has a corresponding burner head and fixed support legs. The gas duct connects to the burner head. Left and right movable support legs are connected to the left and right sides of the burner head bracket. When the left and right movable support legs are open, they form a cookware support frame with the fixed support legs. When folded, the left and right movable support legs can be folded and stowed. It features a small packaging size, simple assembly and disassembly, and convenient portability.

[0003] However, the existing gas stoves have the following shortcomings during use: they lack a limiting structure to prevent the burner head support from rotating in the folding direction or in the unfolding direction. Generally, after the burner head support is opened and the gas cylinder is installed, the shell is closed, and the shell is used to prevent the burner head support from rotating in the folding direction. This operation is inconvenient, and opening and closing the shell is also inconvenient. If the cover is not closed, it will directly affect the limiting effect on the burner head support.

[0004] Therefore, existing technologies need further development. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide a rotating structure and folding stove for a folding stove, so as to solve the technical problem that the folding stove in the related technology does not have a limiting structure to prevent the burner head support from rotating in the folding direction or to prevent the burner head support from rotating in the unfolding direction.

[0006] To achieve the above technical objectives, the present invention adopts the following technical solution: a folding stove rotating structure is provided, comprising: a stove base, on which a limiting block is provided, the limiting block protruding from the surface of the stove base; a rotating base, rotatably connected to the stove base, the bottom of the rotating base having a recessed limiting groove, the shape of the limiting groove matching the shape of the limiting block; and a burner head bracket, used to fix the burner head, the burner head bracket being mounted on the rotating base and rotatably connected to the stove base via the rotating base, so that the burner head bracket can switch between an unfolded state and a folded state. When the burner head bracket is switched to the unfolded state, the limiting block abuts against the side wall of the rotating base to prevent the burner head bracket from rotating in the folding direction. When the burner head bracket is switched to the folded state, the limiting block is embedded in the limiting groove.

[0007] Furthermore, the limiting groove includes a limiting groove guide surface, which is continuously disposed on the side wall of the limiting groove along the circumference of the limiting groove. The limiting groove guide surface is used to guide the limiting block into or out of the limiting groove.

[0008] Furthermore, the limiting block is provided with a first guide slope that gradually slopes downward in the direction of rotation and unfolding of the furnace head support; the limiting block is provided with a second guide slope that gradually slopes downward in the direction of rotation and folding of the furnace head support.

[0009] Furthermore, the rotating seat includes a partition plate, which is disposed at the bottom of the rotating seat, and a limit groove is formed on the partition plate.

[0010] Furthermore, the rotating structure of the folding stove includes a rotating cavity disposed on a rotating base, a first limiting component disposed in the rotating cavity, the first limiting component protruding from the inner surface of the rotating cavity; a rotating sleeve disposed on the stove base, at least a portion of the rotating base being rotatably disposed within the rotating sleeve, a second limiting component and a third limiting component corresponding to the first limiting component disposed in the rotating sleeve, both the second limiting component and the third limiting component protruding from the inner surface of the rotating sleeve, the second limiting component and the third limiting component being circumferentially distributed around the axis of the rotating sleeve, the second limiting component being located on the side of the third limiting component closer to the rotating unfolding direction of the burner head support, when the burner head support is switched to the unfolded state, the first limiting component abuts against the second limiting component to stop the burner head support from rotating in the folding direction, when the burner head support is switched to the folded state, the first limiting component abuts against the third limiting component to stop the burner head support from rotating in the unfolding direction.

[0011] Furthermore, the second limiting component includes a limiting sidewall, which is located on the side of the second limiting component away from the third limiting component. When the burner head support is switched to the unfolded state, the limiting sidewall abuts against the first limiting component.

[0012] Furthermore, the third limiting component includes a stop groove, which is recessed at the top of the third limiting component. When the burner head support is switched to the folded state, the first limiting component is embedded in the stop groove.

[0013] Furthermore, the second limiting component includes: a third guide slope that is gradually inclined downward in the direction of rotation and folding of the burner head support; and a fourth guide slope that is gradually inclined downward in the direction of rotation and unfolding of the burner head support.

[0014] Furthermore, the third limiting component includes: a fifth guide slope that gradually slopes downward in the direction of rotation and folding of the burner head support; and a sixth guide slope that gradually slopes downward in the direction of rotation and unfolding of the burner head support, wherein the fifth guide slope and the sixth guide slope are respectively provided on both sides of the stop groove.

[0015] Furthermore, the rotary base is equipped with an electronic ignition switch for controlling the combustion of the burner head. The electronic ignition switch includes a knob, and the knob has two knob slots, which are respectively located on opposite sides of the knob.

[0016] A folding stove, comprising the aforementioned folding stove rotating structure. Beneficial effects: 1. This embodiment forms a bidirectional limiting mechanism by setting a protruding limiting block on the fixed component stove base and setting a matching limiting groove and side wall on the rotating seat. It can achieve anti-folding limiting through "side wall abutment" in the unfolded state of the stove head support, and achieve anti-unfolding limiting through "block groove embedding" in the folded state. This solves the technical problem in related technologies that folding stoves do not have a limiting structure to prevent the stove head support from rotating in the folding direction or to prevent the stove head support from rotating in the unfolding direction.

[0017] 2. By setting a first limiting component in the rotating cavity of the rotating seat, and setting a second and third limiting component circumferentially spaced in the rotating sleeve of the stove base, a double limiting protection is formed with the aforementioned limiting block. When the stove head support is switched to the unfolded state, the limiting block abuts against the side wall of the rotating seat, and the second limiting component abuts against the first limiting component to achieve double anti-folding locking. When switched to the folded state, the limiting block is embedded in the limiting groove, and the third limiting component abuts against the first limiting component to achieve double anti-unfolding locking. This further effectively solves the positional stability problem of the folding stove in the two states, and significantly improves the safety and reliability of the product.

[0020] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0021] According to an embodiment of this utility model, a rotating structure for a folding stove is provided. Please refer to [link / reference]. Figures 1 to 10 The furnace includes: a furnace base 1, on which a limiting block 11 is provided, the limiting block 11 protruding from the surface of the furnace base 1; a rotating base 2, which is rotatably connected to the furnace base 1, and the bottom of the rotating base 2 is provided with a recessed limiting groove 21, the shape of which matches the shape of the limiting block 11; and a furnace head support 3, which is used to fix the furnace head 4. The furnace head support 3 is installed on the rotating base 2 and is rotatably connected to the furnace base 1 through the rotating base 2, so that the furnace head support 3 can switch between an unfolded state and a folded state. When the furnace head support 3 is switched to the unfolded state, the limiting block 11 abuts against the side wall of the rotating base 2 to prevent the furnace head support 3 from rotating in the folding direction. When the furnace head support 3 is switched to the folded state, the limiting block 11 is embedded in the limiting groove 21.

[0022] By setting the limiting block 11, it can interact with the corresponding structure on the rotating seat 2 when the furnace head support 3 rotates to a specific position, thereby constraining the rotational movement. Setting the limiting block 11 at a certain height can increase the difficulty for the rotating seat 2 to detach, thus increasing the limiting effect on the rotating seat 2.

[0023] Preferably, the height direction of the limiting block 11 is perpendicular to the furnace base 1. The limiting block 11 includes a limiting surface, the extension direction of which is perpendicular to the furnace base 1. The extension direction of the limiting surface is consistent with the side wall of the rotating seat 2 in the unfolded state. When the furnace head support 3 is switched to the unfolded state, the limiting surface abuts against the side wall of the rotating seat 2.

[0024] See Figure 5 The rotating base 2 and the furnace base 1 form a rotating connection pair. A recessed limiting groove 21 is provided at the bottom of the rotating base 2, the shape of which matches the shape of the limiting block 11. The furnace head support 3 is mounted on the rotating base 2 via screws or other detachable structures. The rotating base 2, as a moving part, rotates around the rotation axis together with the furnace head support 3. The contour of the limiting groove 21 precisely corresponds to the cross-sectional shape of the limiting block 11, ensuring that when the two are aligned, the limiting block 11 can be fully embedded in the limiting groove 21, forming a stable fitting connection.

[0025] The burner head support 3 is mounted on the rotating base 2 to fix the burner head 4. It is rotatably connected to the burner base 1 via the rotating base 2, allowing it to switch between an unfolded and folded state. When the burner head support 3 is rotated to the unfolded state, i.e., the working state, the limiting block 11 abuts against the side wall of the rotating base 2, forming a mechanical stop that prevents the burner head support 3 from rotating in the folding direction. This keeps the burner head support 3 stably in the unfolded position, ensuring that the burner head 4 will not be accidentally folded due to external force or vibration during use, thus guaranteeing the stability and safety of the cooking process.

[0026] See Figure 9 When the burner head support 3 is rotated to the folded state, the limiting groove 21 on the rotating base 2 rotates precisely to align with the limiting block 11 on the burner base 1, and the limiting block 11 is embedded in the limiting groove 21. This embedded state locks the rotating base 2 and the burner base 1 in the circumferential direction, forming a stable connection and effectively preventing the burner head support 3 from rotating in the unfolded direction. This structure ensures the compactness and stability of the stove in the folded state and prevents the burner head support 3 from accidentally popping open during carrying or storage.

[0027] In some embodiments, by providing a protruding limiting block 11 on the fixed component stove base 1 and providing a matching limiting groove 21 and sidewall on the rotating base 2, the burner head support 3 is prevented from being raised in the folded or unfolded state. In the folded or unfolded state, the burner head support 3 can maintain contact with the rotating base 2, thereby improving the structural stability of the folding stove.

[0028] This embodiment forms a bidirectional limiting mechanism by setting a protruding limiting block 11 on the fixed component stove base 1 and a matching limiting groove 21 and side wall on the rotating base 2. It can achieve anti-folding limiting through "side wall abutment" in the unfolded state of the stove head support 3, and anti-unfolding limiting through "block groove embedding" in the folded state. This solves the technical problem in related technologies that folding stoves do not have a limiting structure to prevent the stove head support from rotating in the folding direction or in the unfolding direction.

[0029] In the rotating structure of the folding stove in this embodiment, see... Figure 5 The limiting groove 21 includes a limiting groove guide surface 211, which is continuously arranged along the circumference of the limiting groove 21 on the side wall of the limiting groove 21. The limiting groove guide surface 211 is used to guide the limiting block 11 into or out of the limiting groove 21. By providing a continuous limiting groove guide surface 211 on the side wall of the limiting groove 21, a reliable guiding path is provided for the entry and exit of the limiting block 11, reducing the operating resistance of the burner head support 3 during the switching between unfolded and folded states, and ensuring that the burner head support 3 moves smoothly and steadily.

[0030] Specifically, the guide surface 211 of the limiting groove, as a guide slope or arc transition surface provided on the side wall of the limiting groove 21, mainly serves to provide a smooth guide path for the entry and exit of the limiting block 11. When the furnace head support 3 rotates from the unfolded state to the folded state, the rotating seat 2 rotates accordingly, and the limiting groove 21 on it gradually turns to align with the protruding limiting block 11 on the furnace seat 1. During this process, the end of the limiting block 11 first contacts the guide surface 211 of the limiting groove. The inclined or arc-shaped surface of the guide surface 211 of the limiting groove will generate a component force along the rotation direction, guiding the limiting block 11 to smoothly slide into the groove of the limiting groove 21, and finally fully embed, completing the locking of the folded state.

[0031] Specifically, when the burner head support 3 rotates from the folded state to the unfolded state, the rotation of the rotating seat 2 will also cause the limiting groove guide surface 211 to interact with the limiting block 11. As the rotation continues, the limiting groove guide surface 211 will push the limiting block 11 to slide along its surface, guiding the limiting block 11 to gradually break away from the constraint of the limiting groove 21. This guiding effect reduces the resistance of the limiting block 11 to break out of the limiting groove 21, ensuring the smoothness of the state switching process.

[0032] It is understandable that the guide surface 211 of the limiting groove can be an inclined surface or an arc surface, both of which can achieve the guiding function of the limiting block 11.

[0033] In the rotating structure of the folding stove in this embodiment, see... Figure 4The limiting block 11 is provided with a first guide slope 111 that gradually slopes downward in the direction of rotation and unfolding of the furnace head support 3; the limiting block 11 is also provided with a second guide slope 112 that gradually slopes downward in the direction of rotation and folding of the furnace head support 3. By providing the first guide slope 111 and the second guide slope 112 that slope downward in the unfolding and folding directions respectively on the limiting block 11, a bidirectional guiding path is provided for the interaction between the rotating seat 2 and the limiting block 11 during the state switching process, which significantly reduces the motion resistance, avoids rigid impact, and ensures the smoothness and reliability of the furnace head support 3 in switching between the unfolded and folded states.

[0034] Specifically, when the burner head support 3 rotates from the folded state to the unfolded state, the rotating seat 2 rotates accordingly, and its side wall or the edge of the limiting groove 21 first contacts the second guide slope 112. Since the slope is inclined downward in the unfolding direction, the rotating seat 2 will gradually rise along the guide of the slope during the rotation, thereby overcoming the obstruction of the limiting block 11 and realizing the smooth disengagement of the limiting block 11 from the limiting groove 21. By setting the second guide slope 112, the disengagement resistance is significantly reduced, ensuring that the unfolding action is easy and smooth.

[0035] When the burner head support 3 rotates from the unfolded state to the folded state, the side wall of the rotating seat 2 or the edge of the limiting groove 21 first contacts the first guide slope 111. During rotation, the rotating seat 2 gradually rises along the guide slope, and then gradually slides down along the guide slope 112, causing the limiting block 11 to slide smoothly into the groove of the limiting groove 21. This guiding action ensures that the limiting block 11 can accurately and smoothly enter the limiting groove 21 during the folding process, avoiding misalignment or hard impact.

[0036] In the rotating structure of the folding stove in this embodiment, see... Figure 5 The rotating seat 2 includes a partition 22, which is disposed at the bottom of the rotating seat 2, and a limiting groove 21 is formed on the partition 22. Specifically, the bottom of the rotating seat 2 is provided with a cavity, and the partition 22 is embedded in the cavity at the bottom of the rotating seat 2.

[0037] In the rotating structure of the folding stove in this embodiment, see... Figure 4-6 And Figure 9The rotating structure of the folding stove includes a rotating cavity 23 disposed on a rotating base 2, a first limiting component 24 disposed in the rotating cavity 23, the first limiting component 24 protruding from the inner surface of the rotating cavity 23; a rotating sleeve 12 is provided on the stove base 1, at least a portion of the rotating base 2 is rotatably disposed within the rotating sleeve 12, the rotating sleeve 12 is provided with a second limiting component 13 and a third limiting component 14 corresponding to the first limiting component 24, both the second limiting component 13 and the third limiting component 14 protruding from the inner surface of the rotating sleeve 12. The second limiting component 13 and the third limiting component 14 are circumferentially distributed around the axis of the rotating sleeve 12. The second limiting component 13 is located on the side of the third limiting component 14 closer to the rotation and unfolding direction of the burner head support 3. When the burner head support 3 is switched to the unfolded state, the first limiting component 24 abuts against the second limiting component 13 to stop the burner head support 3 from rotating in the folding direction. When the burner head support 3 is switched to the folded state, the first limiting component 24 abuts against the third limiting component 14 to stop the burner head support 3 from rotating in the unfolding direction.

[0038] It should be noted that the folding stove rotation structure of this embodiment also includes a positioning component during the state switching process, which is used to limit the movement stroke of the burner head support 3 and to position the burner head support 3. For example, in some embodiments, the rotating base 2 includes a first positioning part and a second positioning part arranged at a certain central angle interval, and the rotating sleeve 12 is provided with a first stop surface and a second stop surface arranged at a certain central angle interval. When the burner head support 3 is in the folded state, the first positioning part abuts against the first stop surface for limitation, and when the burner head support 3 is in the unfolded state, the second positioning part abuts against the second stop surface for limitation.

[0039] Specifically, when the burner head support 3 switches from the folded state to the unfolded state, the first limiting component 24 rotates together with the rotating seat 2. As it rotates, the first limiting component 24 gradually passes the second limiting component 13. When the first limiting component 24 stops rotating with the rotating seat 2 under the action of the positioning component, the first limiting component 24 abuts against the second limiting component 13. This abutment forms a mechanical stop, preventing the burner head support 3 from rotating in the folding direction. Meanwhile, the positioning component prevents the burner head support 3 from continuing to rotate in the unfolded direction, thereby stably locking the burner head support 3 in the unfolded working position and preventing accidental folding during use.

[0040] Specifically, when the burner support 3 rotates from the unfolded state to the folded state, the first limiting component 24 passes over the second limiting component 13 as it rotates, and stops rotating with the rotating seat 2 under the action of the positioning component, and finally comes into contact with the third limiting component 14. By setting the third limiting component 14, when the burner support 3 switches to the folded state, it stops the burner support 3 from continuing to rotate in the unfolded direction, ensuring that it remains stable in the folded state and preventing the folded stove from accidentally popping open during carrying or storage.

[0041] By setting a first limiting component 24 in the rotating cavity 23 of the rotating seat 2, and setting a second limiting component 13 and a third limiting component 14 circumferentially spaced in the rotating sleeve 12 of the stove base 1, a double limiting protection is formed with the aforementioned limiting block 11. When the stove head support 3 is switched to the unfolded state, the limiting block 11 abuts against the side wall of the rotating seat 2, and the second limiting component 13 abuts against the first limiting component 24 to achieve double anti-folding locking. When switched to the folded state, the limiting block 11 is embedded in the limiting groove 21, and the third limiting component 14 abuts against the first limiting component 24 to achieve double anti-unfolding locking. This further effectively solves the positional stability problem of the folding stove in the two states, and significantly improves the safety and reliability of the product.

[0042] It should be noted that the first limiting component 24, the second limiting component 13, and the third limiting component 14 are closer to the rotation center of the burner head support 3, while the limiting block 11 is further away from the rotation center of the burner head support 3 compared to the first limiting component 24, the second limiting component 13, and the third limiting component 14. The two sets of limiting structures are set at different positions, which further improves the limiting effect and positional stability of the folding stove in both states.

[0043] In the rotating structure of the folding stove in this embodiment, see... Figure 4 The second limiting component 13 includes a limiting sidewall 131, which is located on the side of the second limiting component 13 away from the third limiting component 14. When the burner head support 3 is switched to the unfolded state, the limiting sidewall 131 abuts against the first limiting component 24.

[0044] Specifically, when the burner head support 3 switches from the folded state to the unfolded state, the first limiting component 24 rotates together with the rotating seat 2. As it rotates, the first limiting component 24 gradually passes over the second limiting component 13, so that the first limiting component 24 comes to the side where the limiting side wall 131 is located. When the first limiting component 24 stops rotating with the rotating seat 2 under the action of the positioning component, the first limiting component 24 abuts against the limiting side wall 131. This abutment forms a mechanical stop, preventing the burner head support 3 from rotating in the folding direction. Meanwhile, the positioning component prevents the burner head support 3 from continuing to rotate in the unfolded direction, thereby stably locking the burner head support 3 in the unfolded working position and preventing accidental folding during use.

[0045] In the rotating structure of the folding stove in this embodiment, see... Figure 4 The third limiting component 14 includes a stop groove 141, which is recessed at the top of the third limiting component 14. When the burner head support 3 is switched to the folded state, the first limiting component 24 is embedded in the stop groove 141.

[0046] Specifically, when the burner head support 3 rotates from the unfolded state to the folded state, the rotating seat 2 stops rotating under the action of the positioning component, and finally the first limiting component 24 is embedded in the stop groove 141. By setting the third limiting component 14, when the burner head support 3 switches to the folded state, the stop of the burner head support 3 from continuing to rotate in the unfolded direction, while the positioning component prevents the burner head support 3 from continuing to rotate in the folded direction, thereby stably locking the burner head support 3 in the folded working position, ensuring that it remains stable in the folded state, and preventing it from accidentally popping open during carrying or storage.

[0047] In the rotating structure of the folding stove in this embodiment, see... Figure 4 The second limiting component 13 includes a third guide slope 132, which is gradually inclined downward in the direction of rotation and folding of the burner head support 3, and a fourth guide slope 133, which is gradually inclined downward in the direction of rotation and unfolding of the burner head support 3, respectively disposed on opposite sides of the second limiting component 13.

[0048] Specifically, when the burner head support 3 switches from the folded state to the unfolded state, the first limiting component 24 rotates together with the rotating seat 2. The end of the first limiting component 24 first contacts the fourth guide slope 133. As the burner head support 3 continues to rotate, the first limiting component 24 will gradually "climb" along the guide slope during the rotation process, thereby overcoming the obstruction of the second limiting component 13 and gradually passing over the second limiting component 13, so that the first limiting component 24 comes to the side where the limiting side wall 131 is located. During the rotation process, the first limiting component 24 will gradually "descend" along the guide slope 132. When the first limiting component 24 stops rotating with the rotating seat 2 under the action of the positioning component, the first limiting component 24 abuts against the limiting side wall 131, thereby avoiding the impact and jamming caused by direct collision when the first limiting component 24 approaches the locking position, improving the stability of the unfolding process, and ensuring the limiting effect of the second limiting component 13.

[0049] In the rotating structure of the folding stove in this embodiment, see... Figure 4 The third limiting component 14 includes: a fifth guide slope 142 that gradually slopes downward in the direction of rotation and folding of the burner head support 3; and a sixth guide slope 143 that gradually slopes downward in the direction of rotation and unfolding of the burner head support 3. The fifth guide slope 142 and the sixth guide slope 143 are respectively provided on both sides of the stop groove 141.

[0050] Specifically, when the burner head support 3 rotates from the unfolded state to the folded state, the end of the first limiting component 24 first contacts the sixth guide slope 143. As the burner head support 3 continues to rotate, the first limiting component 24 will gradually "climb" along the guidance of the sixth guide slope 143 during the rotation process. As the rotating seat 2 stops rotating under the action of the positioning component, the first limiting component 24 is finally embedded in the stop groove 141. When the burner head support 3 rotates from the folded state to the unfolded state, the first limiting component 24 will gradually "descend" along the guidance of the sixth guide slope 143 during the rotation process, thereby avoiding the impact and jamming caused by direct collision when the first limiting component 24 approaches the locking position, improving the stability of the unfolding process, and ensuring the limiting effect of the second limiting component 13.

[0051] In some embodiments, the first limiting member 24 includes a seventh guide slope 241, which is gradually inclined upward in the direction of rotational folding of the burner head support 3, and an eighth guide slope 242, which is gradually inclined upward in the direction of rotational unfolding of the burner head support 3, respectively disposed on opposite sides of the first limiting member 24. By providing the seventh guide slope 241 and the eighth guide slope 242, which are inclined upward in different rotational directions, on opposite sides of the first limiting member 24, bidirectional disengagement guidance is provided for the interaction between the first limiting member 24 and the second and third limiting members during state switching. The seventh guide slope 241 and the eighth guide slope 242 significantly reduce the operating resistance when the limiting lock state is released, avoid hard impact, and ensure the smoothness and reliability of the burner head support 3 switching between unfolded and folded states.

[0052] Specifically, the rotating base 2 and the furnace head support 3 are fastened together by screws.

[0053] In the rotating structure of the folding stove in this embodiment, see... Figure 8 The rotating base 2 is equipped with an electronic ignition switch 7 for controlling the combustion of the burner head 4. The electronic ignition switch 7 includes a knob 71, and the knob 71 has two knob slots 72, which are respectively located on opposite sides of the knob 71. In this way, when rotating the control knob 71, the two knob slots 72 can just accommodate the thumb and forefinger of a person's hand, effectively improving the comfort of holding and the convenience of operation, and solving the problems of poor feel and difficulty in applying force of traditional "single-shaped" or round knobs.

[0054] Preferably, the knob 71 is S-shaped.

[0055] In the folding stove of this embodiment, see Figure 10The furnace head support 3 is provided with a support shaft, the rotating seat 2 is provided with a first support shaft mounting hole, and the furnace base 1 is provided with a support shaft mounting column. The support shaft mounting column is provided with a second limiting component 13 and a third limiting component 14 on its periphery. The support shaft mounting column is provided with a second support shaft mounting hole. The support shaft passes through the first support shaft mounting hole and the second support shaft mounting hole respectively and is fastened to the screw located on the furnace base 1.
