[0017] In one of the embodiments, the assembly groove has an opening arranged downward, the bracket is installed in the assembly groove through the opening, and the lower shell body also includes a lower shell cover, and the lower shell cover is installed at the opening of the assembly groove.

[0018] In this way, the opening of the assembly groove is arranged downward, and the assembly groove cannot be observed from the top and side surfaces of the grilling machine, so the appearance of the grilling machine can be kept beautiful. The lower shell cover can prevent the bracket from falling out of the assembly groove and keep the appearance of the lower shell beautiful.

[0019] In one embodiment, the number of the hinge assembly is at least one, and each hinge assembly corresponds to one reset member.

[0020] With such an arrangement, the reset member and the hinge assembly are arranged one by one to ensure that each hinge assembly is not prone to jamming during the descent process, thereby ensuring the balance and stability of the upper cover assembly and the hinge assembly during the lifting process.

[0021] In one embodiment, the first accommodating groove has a first opening arranged upward and a second opening arranged outward, the first opening is connected to the second opening, the hinge body can move up and down in the first accommodating groove and at least partially extend out of the first opening, and when the hinge body moves upward to break away from the restriction of the first accommodating groove, the hinge body can rotate between the first opening and the second opening.

[0047] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "or / and" used herein includes any and all combinations of one or more related listed items.

[0048] Grilling and baking appliances such as grilling machines usually include a base assembly and an upper cover assembly, wherein the upper cover assembly and the base assembly are rotatably connected by a hinge assembly, so that the upper cover assembly can be opened or closed relative to the base assembly. When the grilling and baking machine is closed for cooking, such as making pancakes, the depth of the cooking space of the grilling and baking machine is fixed, resulting in the pancake being restricted by the upper cover assembly when it expands and unable to expand fully, so that the cooked pancake is firm and has a poor taste. At present, there are grilling and baking machines with hinge assemblies that can move up and down when the food expands to change the distance between the upper cover assembly and the base assembly. Among them, some grilling and baking machines control the lifting and lowering of the upper cover assembly by manually adjusting the hinge assembly, but this method is usually step-by-step adjustment, which may cause a gap between the upper baking tray and the top of the food, affecting the cooking effect; the applicant has proposed a solution for some grilling and baking machines that controls the lifting and lowering of the upper cover assembly by the push of the food and the gravity of the upper cover assembly to adjust the depth of the cooking space, but this method is prone to jamming of the hinge assembly during the descent process, which brings a bad experience to the user.

[0049] In order to solve the above problems, Figures 1 to 19 As shown, the utility model provides a frying and grilling utensil, which can float up and down and is not prone to getting stuck.

[0050] like Figures 1 to 3As shown, specifically, the grilling device includes an upper cover assembly 20, a base assembly 10, a hinge assembly 30 and a reset member 40, wherein: the upper cover assembly 20 includes an upper shell 21 and an upper grill pan 22 arranged on the upper shell 21; the base assembly 10 includes a lower shell 11 and a lower grill pan 12 arranged on the lower shell 11, and the lower shell 11 is provided with a first accommodating groove 111; one end of the hinge assembly 30 is rotatably connected to the lower shell 11, and the other end is rotatably connected to the upper shell 21, the hinge assembly 30 is at least partially located in the first accommodating groove 111 and can be lifted and lowered relative to the lower shell 11; the reset member 40 is installed in the first accommodating groove 111, one end of the reset member 40 is connected to the hinge assembly 30, and the other end is connected to the lower shell 11, and the reset member 40 has a downward force on the hinge assembly 30.

[0051] In the grilling and baking utensil provided by the embodiment of the utility model, the upper cover assembly 20 can be rotated to open or close the cover relative to the base assembly 10 through the hinge assembly 30, which is convenient for users to use; when cooking food that is easy to expand, the food can lift up the upper baking tray 22, that is, lift up the upper cover assembly 20 and the hinge assembly 30, at this time, the depth of the cooking cavity is increased, thereby avoiding compacting the food and ensuring the fluffy taste of the food; because the upper cover assembly 20 and the hinge assembly 30 are lifted up by the upper baking tray 22 pushed by the food during the expansion process, it can Stepless lifting is achieved to ensure that the upper baking tray 22 is always in contact with the top of the food, thereby ensuring the cooking effect; when the upper cover assembly 20 is flipped to the upright state, the hinge assembly 30 can be lowered to rest against the lower shell body 11 under the action of its own gravity and the reset member 40 to keep the upper cover assembly in the upright state; during the descending process, the reset member 40 always has a downward force acting on the hinge assembly 30, which can avoid the hinge assembly 30 from getting stuck, thereby solving the problem of the hinge assembly not being smooth during the descent process and causing a bad feel.

[0052] Furthermore, since the thickness of the lower shell 11 is usually greater than that of the upper shell 21, the lifting and lowering of the hinge assembly 30 relative to the lower shell 11 can fully utilize the thickness space of the lower shell 11, so that the lifting and lowering of the hinge assembly 30 has a larger lifting stroke, and the upper shell 21 has a larger up and down floating stroke, which is suitable for cooking various types of food.

[0053] One end of the hinge assembly 30 is rotatably connected to the lower shell 11, and the other end is rotatably connected to the upper shell 21, and the hinge assembly 30 can be raised and lowered relative to the lower shell 11, so that the upper shell 21 can be in a closed state, a 90° open state, and a 180° unfolded state relative to the lower shell 11, so that the grilling appliance has different cooking modes, which is convenient for users to use in different scenarios. It can be understood that "the upper shell 21 is in a closed state relative to the lower shell 11" means that the upper shell 21 covers the lower shell 11. At this time, the food can lift up the upper shell 21, so that the upper shell 21 is in a suspended state. It can be seen that "the upper shell 21 is in a closed state relative to the lower shell 11" includes both the closed state (such as the closed state) in which the upper shell 21 contacts the lower shell 11 (such as the closed state). Figures 4 to 6 ), and also includes a suspended state where the upper shell 21 and the lower shell 11 are separated by a certain distance (as shown in Figures 7 to 9 As shown). “The upper shell 21 is in a 90° open state relative to the lower shell 11” refers to a state where the upper shell 21 is approximately at an angle of 90° relative to the lower shell 11. Preferably, when the upper shell 21 is in a 90° open state relative to the lower shell 11, the angle between the upper shell 21 and the lower shell 11 is greater than 90°. Further, the angle between the upper shell 21 and the lower shell 11 is θ. In the 90° open state, 90°<θ≤105°, as shown. Figures 10 to 12 It is worth mentioning that the 90° open state can also be understood as the upper cover assembly 20 being in an upright state. "The upper shell 21 is in a 180° unfolded state relative to the lower shell 11" means that the upper shell 21 is flipped to the other side at an angle of approximately 180° relative to the lower shell 11, such as Figures 13 to 15 shown.

[0054] like Figures 4 to 9 As shown, when the upper shell 21 is in a closed state relative to the lower shell 11, the hinge assembly 30 is located on the inner side of the lower shell 11 and the upper shell 21. In the prior art, there is a situation where the hinge assembly 30 protrudes from the side walls of the lower shell 11 and the upper shell 21. The protrusion of the hinge assembly 30 from the side walls of the lower shell 11 and the upper shell 21 will affect the appearance of the grilling utensil, resulting in an increase in the specific volume of the grilling utensil. When designing the packaging structure of the grilling utensil, it is necessary to set a groove on the packaging material for the protruding part, resulting in a complex packaging design. In the present application, since the hinge assembly 30 is located on the inner side of the lower shell 11 and the upper shell 21, the setting of the hinge assembly 30 will not affect the appearance of the grilling utensil, will not cause the specific volume of the grilling utensil to increase, and there is no need to design a packaging structure specifically for the hinge assembly 30.

[0055] like Figures 13 to 15 As shown, in one embodiment, when the upper housing 21 is in a 180° unfolded state relative to the lower housing 11, the upper surface of the upper housing 21, the upper surface of the hinge assembly 30 and the upper surface of the lower housing 11 are substantially located in the same plane. In this way, cleaning the grilling utensil is very convenient and quick.

[0056] In another embodiment, when the upper shell 21 is unfolded 180 degrees relative to the lower shell 11, the upper edge end surface of the upper grill 22, the upper surface of the hinge assembly 30 and the upper edge end surface of the lower grill 12 are basically located in the same plane. In this way, it is very convenient and quick to clean the grilling utensil. In this embodiment, the upper edge end surface of the upper grill 22 covers the upper surface of the upper shell 21, or the upper edge end surface of the upper grill 22 is flush with the upper surface of the upper shell 21 (such as Figure 14 to Figure 15 The upper edge of the lower baking pan 12 covers the upper surface of the lower shell 11, or the upper edge of the lower baking pan 12 is flush with the upper surface of the lower shell 11 (as shown). Figure 14 to Figure 15 shown).

[0057] The upper cover assembly 20 further includes a handle 23, which is disposed at one end of the upper shell 21 away from the hinge assembly 30. When the upper shell 21 is in a 180° unfolded state relative to the lower shell 11, the handle 23 is used to support the upper shell 21. Figures 13 to 15 In this embodiment, the handle 23 is in the shape of a U-shaped rod, and both ends are connected to the upper shell 21 near the edge. In this way, the handle 23 has a large supporting surface, can well support the upper shell 21, and is convenient for users to hold.

[0058] like Figures 2 to 3 As shown, the hinge assembly 30 includes a hinge body 31, a lower rotating shaft 32 and an upper rotating shaft 33. One end of the hinge body 31 is rotatably connected to the lower housing 11 through the lower rotating shaft 32, and the other end of the hinge body 31 is rotatably connected to the upper housing 21 through the upper rotating shaft 33. One end of the reset member 40 is connected to the lower rotating shaft 32, and the other end of the reset member 40 is connected to the lower housing 11. In this way, the structure of the hinge assembly 30 is very simple. When the hinge assembly 30 rises, the end of the reset member 40 connected to the lower rotating shaft 32 rises synchronously with the lower rotating shaft 32, and the end of the reset member 40 connected to the lower housing 11 is fixed relative to the base assembly 10, so that the two ends of the reset member 40 are stretched, and a force toward the lower housing 11 is applied to the lower rotating shaft 32 to assist the hinge assembly 30 to descend and avoid jamming.

[0059] In this embodiment, the hinge body 31 is in the shape of a column, and has a simple structure, which is convenient for the hinge body 31 to be raised and lowered, and is convenient for the hinge body 31 to support the upper shell 21 in a 90° open state. In this embodiment, the hinge body 31 is a square column, but is not limited thereto. In other embodiments, the hinge body 31 may also be a circular column, an elliptical column, or other polygonal columns (such as a hexagonal column, an octagonal column), or other shapes.

[0060] like Figure 1 and Fig.17As shown, the upper shell 21 is provided with a second accommodating groove 211, one end of the hinge body 31 extends into the second accommodating groove 211 and is rotatably connected to the upper shell 21. The second accommodating groove 211 has a first notch 2111 and a second notch 2112 that are adjacent and connected. When the upper shell 21 is in a closed state relative to the lower shell 11, the first notch 2111 faces the lower shell 11, and the second notch 2112 faces the outside of the upper shell 21. The hinge body 31 can rotate between the first notch 2111 and the second notch 2112. The top wall of the second notch 2112 is provided with a stop surface 2113. Figure 5 and Figure 8 As shown, when the upper shell 21 is in a closed state relative to the lower shell 11, the hinge body 31 is in an upright state, and the hinge body 31 extends from the first notch 2111 into the second receiving groove 211. At this time, the food expands and can lift up the upper shell 21. Figure 2 and Fig.11 As shown, when the upper shell 21 is in an open position at 90° relative to the lower shell 11 , the hinge body 31 is in an upright position, the hinge body 31 extends from the second notch 2112 into the second accommodating groove 211 , and the stop surface 2113 abuts against one side of the hinge body 31 .

[0061] In this way, when the upper shell 21 is in the 90° open state relative to the lower shell 11, the hinge body 31 is in an upright state, that is, the hinge body 31 will not rotate relative to the lower shell 11, so that the upper shell 21 can be supported by the stop surface 2113 abutting against the hinge body 31, so that the upper shell 21 remains in the 90° open state. It is worth mentioning that "the hinge body 31 is in an upright state" means that the hinge body 31 is roughly upright, including both the situation that the hinge body 31 is perpendicular to the horizontal plane and the situation that the hinge body 31 is inclined at a small angle relative to the vertical plane.

[0062] like Figure 1 and Fig.16 As shown, in this embodiment, the upper rotating shaft 33 is configured as a pin, and the hinge body 31 is provided with an upper shaft hole 312 corresponding to the upper rotating shaft 33 , and the pin and the upper shaft hole 312 are rotationally matched to rotate the hinge body 31 to connect the hinge body 31 to the upper shell 21 .

[0063] like Figure 1 to Figure 2 As shown, the first receiving groove 111 has a first opening 1111 disposed upward and a second opening 1112 disposed outward, where "disposed outward" means toward the outside of the lower housing 11, that is, the outside of the grilling utensil. The first opening 1111 is connected to the second opening 1112, and the hinge body 31 can move up and down in the first receiving groove 111 and at least partially extend out of the first opening 1111. When the hinge body 31 moves upward to be out of the restriction of the first receiving groove 111, the hinge body 31 can rotate between the first opening 1111 and the second opening 1112.

[0064] like Figure 5 and Figure 8 As shown, when the upper shell 21 is in a closed state relative to the lower shell 11, and the food expands and pushes up the upper shell 21, the upper shell 21 pulls the hinge body 31 to move upward along the depth direction of the first accommodating groove 111. Since the first accommodating groove 111 has a first opening 1111 arranged upward, the hinge body 31 can move upward smoothly, so that the food can push up the upper shell 21. Figure 8 and Fig.11 As shown, when the cover needs to be opened, the user can lift up and flip the upper shell 21, and the hinge body 31 moves upward in the first receiving groove 111 for a distance, and the upper shell 21 rotates relative to the hinge body 31. When the upper shell 21 rotates to the 90° open cover state, the hinge body 31 is limited by the first receiving groove 111 and cannot rotate relative to the lower shell 11, so that the hinge body 31 remains in an upright state, so that the upper shell 21 can be supported in the 90° open cover state. Fig.11 and Fig.14 As shown, the upper shell 21 is then continuously lifted upwards, so that the hinge body 31 is freed from the restriction of the first receiving groove 111, and the hinge body 31 can be rotated from the first opening 1111 to the second opening 1112, so that the hinge body 31 is converted from the upright state to the horizontal state, and the upper shell 21 can be rotated relative to the lower shell 11 to a 180° unfolded state. When the cover needs to be closed, the reverse operation can be performed.

[0065] like Fig.14 As shown, the bottom wall of the second opening 1112 forms a support platform 1113, and when the upper shell 21 is in a 180° unfolded state relative to the lower shell 11, the lower surface of the hinge body 31 rests on the support platform 1113. In this way, the hinge body 31 can be prevented from deflecting relative to the upper shell 21 or the lower shell 11, so that the upper surface of the hinge body 31 can be horizontal, and the gaps between the two ends of the hinge body 31 and the upper shell 21 and the lower shell 11 are small, so that the gaps between the hinge body 31 and the upper shell 21 and the gaps between the hinge body 31 and the lower shell 11 are not easy to enter with oil smoke, thereby facilitating the cleaning of the grilling utensil.

[0066] like Fig.11 and Fig.14 As shown, further, an avoidance groove 1114 is provided on the inner wall of the first receiving groove 111 on the side opposite to the second opening 1112, and the avoidance groove 1114 is used to avoid the end of the hinge body 31 when the hinge body 31 rotates relative to the lower shell 11. In this way, it is convenient to rotate the hinge body 31 when opening the cover, so that the upper shell 21 can be smoothly unfolded to 180 degrees.

[0067] like Figure 1 and Figure 6As shown, the lower housing 11 is provided with a lower shaft hole 112, and the lower shaft hole 112 extends along the height direction of the lower housing 11. The lower shaft 32 is fixed to the hinge body 31, and the lower shaft 32 is rotatably penetrated in the lower shaft hole 112, and can move in the lower shaft hole 112 along the height direction of the lower housing 11; the lower shaft hole 112 is communicated with the first receiving groove 111, and the hinge body 31 is at least partially located in the first receiving groove 111. In this way, by moving the lower shaft 32 along the lower shaft hole 112, at least part of the hinge body 31 can be moved in the first receiving groove 111 along the up-down direction, and by rotating the lower shaft 32 relative to the lower shaft hole 112, the hinge body 31 can be rotated relative to the lower housing 11, so that the hinge body 31 can rotate between the first opening 1111 and the second opening 1112, thereby realizing the conversion of the hinge body 31 between the upright state and the horizontal state.

[0068] In this embodiment, the lower rotating shaft 32 is fixedly connected to the hinge body 31, and the structure is relatively simple and easy to install. Specifically, the lower rotating shaft 32 and the hinge body 31 are an integrated structure, but not limited thereto. In its embodiment, the lower rotating shaft 32 can also be rotatably connected to the hinge body 31. In addition, in other embodiments, the lower shaft hole 112 can also be provided in the hinge body 31, and the lower rotating shaft 32 is connected to the lower shell 11, that is, the hinge body 31 is provided with the lower shaft hole 112, and accordingly, the lower shaft hole 112 extends along the length direction of the hinge body 31, and the lower rotating shaft 32 moves and rotates in the lower shaft hole 112, so that the hinge body 31 can also move and rotate relative to the lower shell 11.

[0069] like Figure 1 to Figure 2 As shown, the lower shell 11 includes a lower shell body 113 and a bracket 114. The lower shell body 113 is provided with an assembly groove. The bracket 114 is installed in the assembly groove and cooperates with the lower shell body 113 to form a first accommodating groove 111; one end of the reset member 40 is fixed to the lower rotating shaft 32, and the other end of the reset member 40 is arranged on the bracket 114. Since the bracket 114 is fixed to the lower shell body 113, when the hinge assembly 30 is raised or lowered, the bracket 114 is always fixed relative to the base assembly 10. When the hinge assembly 30 rises, the end of the reset member 40 connected to the lower rotating shaft 32 rises synchronously with the lower rotating shaft 32, and the end of the reset member 40 connected to the bracket 114 is fixed relative to the base assembly 10, so that the two ends of the reset member 40 are stretched. Since the upper shell 21 and the lower shell 11 are usually processed and formed by injection molding, the lower shell 11 is arranged into multiple parts instead of a whole, which is conducive to demoulding after molding, and is conducive to installing the hinge assembly 30 in the first accommodating groove 111 during installation. In this embodiment, the bracket 114 and the lower shell body 113 cooperate to form not only the first receiving groove 111, but also cooperate to form the lower shaft hole 112. For details, see Figure 1 and Figure 2The upper part of the first receiving groove 111 is formed in the lower shell body 113, and the lower part of the first receiving groove 111 is formed in the bracket 114. The lower shaft hole 112 is a long strip hole, the upper part of the lower shaft hole 112 is formed in the lower shell body 113, and the lower part of the lower shaft hole 112 is formed in the bracket 114. In this embodiment, the bracket 114 and the lower shell body 113 can be connected and fixed by fasteners (such as screws).

[0070] The assembly groove has an opening facing downward, and the bracket 114 is installed in the assembly groove through the opening. The lower shell 11 also includes a lower shell cover 115, and the lower shell cover 115 is installed at the opening of the assembly groove. In this way, the opening of the assembly groove is facing downward, and the assembly groove cannot be observed from the top and side surfaces of the grilling utensil, so the appearance of the grilling utensil can be kept beautiful. The lower shell cover 115 can prevent the bracket 114 from falling out of the assembly groove, and the appearance of the lower shell 11 can be kept beautiful. In this embodiment, the lower shell cover 115 and the bracket 114 can be connected and fixed by fasteners (such as screws).

[0071] like Figure 6 and Fig.18 As shown, the bracket 114 includes a bracket body 1141 and a fixing portion 1142. The fixing portion 1142 is arranged on a side of the bracket body 1141 away from the first receiving groove 111, and a avoidance hole 11411 corresponding to the fixing portion 1142 is arranged on the bracket body 1141. One end of the reset member 40 is fixed to the lower rotating shaft 32, and the other end can pass through the avoidance hole 11411 and be fixed to the fixing portion 1142. The fixing portion 1142 is used to fix one end of the reset member 40 connected to the lower housing 11. The fixing portion 1142 is integrally arranged on the bracket body 1141 to facilitate processing and forming. The fixing portion 1142 is arranged on a side of the bracket body 1141 away from the first receiving groove 111 to prevent the fixing portion 1142 from interfering with the sliding of the lower rotating shaft 32 in the lower shaft hole 112. In other embodiments, the fixing portion 1142 may also be disposed on the inner wall of the first receiving groove 111 , as long as it is ensured that the end of the restoring member 40 connected to the fixing portion 1142 will not rise or fall synchronously with the hinge assembly 30 .

[0072] like Figure 6 and Fig.19As shown, in this embodiment, the reset member 40 includes a tension spring 41 and a fixing ring 42 provided at both ends of the tension spring 41, and the fixing ring 42 is respectively sleeved on the lower rotating shaft 32 and the fixing portion 1142. When the hinge assembly 30 rises, the fixing ring 42 connected to the lower rotating shaft 32 rises synchronously with the lower rotating shaft 32, and the fixing ring 42 connected to the fixing portion 1142 is fixed relative to the base assembly 10, so that the tension spring 41 is stretched and an elastic force toward the lower housing 11 is applied to the lower rotating shaft 32 to assist the hinge assembly 30 to descend and avoid jamming. In this way, the reset member 40 has a simple structure, and the tension spring 41 is stable and reliable when deformed, and has a strong load capacity, so that the stability and reliability of the hinge assembly 30 during the lifting process can be improved, and the service life of the reset member 40 can be extended. Since the lower rotating shaft 32 is a columnar structure, the fixing portion 1142 can also be set as a columnar structure, and fixedly connected to the lower rotating shaft 32 and the fixing portion 1142 through the fixing ring 42, so as to facilitate assembly. In other embodiments, the reset member 40 may also include other elastic elements such as rubber members, compressed gas springs, etc. In addition, both ends of the reset member 40 may also be connected and fixed to the lower shaft 32 and the fixing portion 1142 by fasteners (such as screws), snap connections, interference fits, etc. In this case, the fixing portion 1142 is not limited to a columnar structure, but may also be other structures such as buckles and slots.

[0073] like Figure 1 As shown, the number of hinge assemblies 30 is at least one, and each hinge assembly 30 corresponds to a reset member 40. The reset member 40 is arranged one-to-one with the hinge assembly 30 to ensure that each hinge assembly 30 is not prone to jamming during the descent process, thereby ensuring the balance and stability of the upper cover assembly 20 and the hinge assembly 30 during the lifting process, and avoiding the upper cover assembly 20 from tilting relative to the base assembly 10. In this embodiment, the number of hinge assemblies 30 is two, which can better support the upper cover assembly 20, and also avoid occupying too much space of the upper cover assembly 20 and the base assembly 10. However, it is not limited to this. In other embodiments, the number of hinge assemblies 30 can also be one or three or more.

[0074] When the number of hinge components 30 is two, at least one hinge component 30 is provided with a wire passage 34 for passing a wire. Figure 2 As shown. In this way, the wire will not be exposed outside the grilling utensil, which improves the safety performance of the grilling utensil and helps to maintain the beautiful appearance of the grilling utensil. In this embodiment, one of the hinge components 30 is provided with a wire passage 34. Specifically, as shown Fig.16As shown, a cavity 311 is provided in the hinge body 31, a first through hole 321 is provided in the lower rotating shaft 32, and a second through hole 331 is provided in the upper rotating shaft 33, so that the cavity 311, the first through hole 321 and the second through hole 331 in the hinge body 31 constitute a wire passage 34, through which the wire passes, thereby connecting the electronic components in the upper shell 21 and the lower shell 11. Further, the hinge body 31 includes a main body part 313 and a cover part 314, the main body part 313 is provided with a cavity 311, and the cover part 314 is covered at the opening of the cavity 311, so that it is convenient to load the wire into the hinge body 31.

[0075] In the present application, the base assembly 10 is provided with a lower grilling pan 12, and the upper cover assembly 20 is provided with an upper grilling pan 22, that is, the grilling utensil is a grilling machine with double-sided grilling functions. However, it is not limited thereto, in other embodiments, the upper cover assembly 20 may not be provided with an upper grilling pan 22, but only with a cover body, that is, a grilling machine with single-sided grilling functions.

[0076] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0077] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
