Description

Technical Field

[0001] The invention relates to the technical field of cigar production and processing, and in particular to a method for rolling a "high-speed rail type" cigar. Background Art

[0002] Traditional cigars are shaped like a round head and a flat tail. In recent years, the global cigar market has continued to grow steadily. As the cigar market expands, consumers have higher requirements for the diversity of cigar products. Special-shaped cigar stick designs have emerged, such as the Solomon type, the torpedo type, the snake type, etc. Special-shaped cigar stick design is one of the ways to enhance consumers' smoking experience.

[0003] Cigars are composed of three parts: the cigar core, the binder, and the wrapper. The cigar core is made by separating the tobacco leaves according to their length and then folding them by hand. It is the center of the cigar. The binder is the tobacco leaves placed on the outer layer of the tobacco core to shape the tobacco core. The wrapper is the outermost layer of the cigar and is an important evaluation indicator of the appearance quality of the cigar. Cigar rolling is to roll the cigar core, binder, and wrapper into a cigar.

[0004] The current cigar rolling process is to first roll the cigar core manually, then wrap it with a cigar wrapper to obtain a tobacco embryo, and then shape the tobacco embryo and wrap it with a cigar wrapper to complete the cigar rolling. The tobacco embryo is shaped by a shaper, and the hand-rolled tobacco embryo is placed in the shaper and pressurized to reach a certain specification and shape to ensure that the appearance of the cigar is flat and uniform. However, the current tobacco embryo shaping requires multiple flipping of the tobacco embryo to ensure that the appearance of the cigar is uniform, but flipping requires additional manual operation, which makes the cigar production efficiency low.

[0005] For example, the patent application publication number CN113679093A discloses a method for rolling cigars, wherein the shaping is performed by placing the cigar embryo in a shaping mold, shaping under the action of external force, and shaping for 2 to 3 days, and opening the mold every 5 hours during the shaping process to turn the embryo over. The patent has the following disadvantages: the cigars rolled by the method provided by the patent need to be turned over every 5 hours during shaping to ensure that the shaping pressure of the embryo is consistent and the appearance of the finished product is uniform, but such frequent turning will increase the labor cost and reduce the production efficiency. Summary of the invention

[0006] The existing cigar rolling method requires frequent flipping. In order to solve the above technical problems, the present invention provides a "high-speed rail type" cigar rolling method.

[0007] The specific technical scheme of the present invention is: The present invention provides a method for rolling a "high-speed rail type" cigar, comprising the following steps: Step S1: providing a cigar embryo, wherein the cigar embryo comprises a connected equal diameter section and a uniformly contracted section, wherein the equal diameter sections have the same diameter, and the diameter of the uniformly contracted section decreases uniformly from one end connected to the equal diameter section to the other end; Step S2: providing a shaping device for shaping the tobacco embryos provided in step S1: The shaping device comprises a mold upper cover and a mold base, and the mold upper cover and the mold base are covered to shape the cigarette embryo; The mold base comprises a cigarette embryo shaping groove, the bottom surface of which is a curved surface; the cigarette embryo shaping groove comprises a connected equal diameter area and a uniform shrinkage area, which are respectively used to accommodate the equal diameter section and the uniform shrinkage section of the cigarette embryo, the groove widths of the equal diameter areas are the same, the groove width of the uniform shrinkage area decreases uniformly from one end connected to the equal diameter area to the other end, and the groove depth of the uniform shrinkage area decreases uniformly from one end connected to the equal diameter area to the other end; The mold upper cover comprises a pressing plate, and the pressing plate is embedded in the cigarette embryo shaping groove to press the cigarette embryo; Step S3: placing the cigarette embryos provided in step S1 into the cigarette embryo shaping grooves provided in step S2, closing the mold upper cover and the mold base, and pressing and shaping.

[0008] The existing cigar rolling method requires frequent flipping to make the tobacco embryos evenly stressed. At the same time, a small number of flipping or improper flipping time control can easily cause indentations. In order to solve the flipping problem in the shaping process of cigar rolling, the present invention designs the cigar into a "high-speed rail shape" through the design of special-shaped cigar sticks, and provides a corresponding shaper to make the pressed cigar tobacco embryos into a "high-speed rail shape". In the pressing process, the pressing forms an indentation on the bottom edge of the "high-speed rail" shape. The formation of the indentation is cleverly utilized, so that the rolling method can avoid promoting uniform stress through multiple flipping.

[0009] Specifically, the present invention rolls the tobacco embryo into a shape including an equal diameter section and a uniform shrinkage section, and then the tobacco embryo shaping groove of the shaper is correspondingly set to include an equal diameter area and a uniform shrinkage area, the groove width of the equal diameter area is the same, and the groove width of the uniform shrinkage area is uniformly reduced from one end connected to the equal diameter area to the other end. After pressing, the uniform shrinkage area is pressed to form a "high-speed rail type" head. Since the bottom surface of the tobacco embryo shaping groove is an arc surface, the "high-speed rail type" head with uniformly reduced width (the groove width of the uniform shrinkage area is uniformly reduced from one end connected to the equal diameter area to the other end) can smoothly transition to the equal-width "high-speed rail type" body. After the mold upper cover and the mold base are covered, the pressing plate arranged on the mold upper cover is embedded in the tobacco embryo shaping groove to press the tobacco embryo. The embedding can be understood as the width of the pressing plate being adapted to the groove width, and just being able to be placed in the tobacco embryo shaping groove. After pressing, the periphery of the pressing plate will form traces on the surface of the tobacco embryo, and these traces cleverly become the bottom edge of the "high-speed rail" shape. After the cigarette embryo expands and deforms, the bottom surface of the "high-speed rail" shaped cigarette embryo becomes an arc surface.

[0010] As a preferred embodiment of the above-mentioned rolling method, the lower surface of the pressed plate is a curved surface, and the arc height of the curved surface is 0.8-1.2 mm.

[0011] As a preferred embodiment of the above rolling method, the mold upper cover is provided with a positioning protrusion, and the mold base is provided with a positioning cavity for accommodating the positioning protrusion.

[0012] As a preferred embodiment of the above rolling method, the number of the positioning protrusions is at least 2.

[0013] Further preferably, the number of the positioning protrusions is 3, which are arranged on both sides of the pressing protrusion.

[0014] As a preferred embodiment of the above rolling method, the length of the uniform shrinkage zone is 1 / 4 to 1 / 2 of the length of the uniform diameter zone.

[0015] More preferably, the length of the uniform shrinkage zone is 1 / 3 of the length of the equal diameter zone.

[0016] As a preferred embodiment of the above-mentioned rolling method, the width of the tobacco embryo shaping groove is 0.4-0.6 mm smaller than the maximum diameter of the tobacco embryo.

[0017] As a preferred embodiment of the above rolling method, after the mold upper cover and the mold base are covered, the distance from the lower surface of the pressing plate to the bottom surface of the cigarette embryo shaping groove is 0.4-0.6 mm smaller than the maximum diameter of the cigarette embryo.

[0018] As a preferred embodiment of the above rolling method, the pressing time is not less than 5 hours.

[0019] As a preferred embodiment of the above rolling method, after the mold upper cover and the mold base are closed, both ends of the cigarette embryo shaping groove are connected to the air.

[0020] As a preferred embodiment of the above rolling method, the rolling method further comprises the following steps: After pressing and shaping, the tail of the tobacco embryo is cut under the condition that the mold cover and the mold base are closed.

[0021] Compared with the prior art, the present invention has the following technical effects: 1. The existing cigar rolling method requires frequent flipping to make the tobacco embryos evenly stressed. At the same time, a small number of flipping or improper flipping time control can easily cause indentations. In order to solve the flipping problem in the shaping process of cigar rolling, the present invention designs the cigar into a "high-speed rail shape" through the design of special-shaped cigar sticks, and provides a corresponding shaper to press the cigar tobacco embryo into a "high-speed rail shape". In the pressing process, the pressing forms an indentation on the bottom edge of the "high-speed rail" shape. The formation of the indentation is cleverly utilized, so that the rolling method can avoid promoting uniform stress through multiple flipping.

[0022] 2. The present invention rolls the tobacco embryo into a shape including an equal diameter section and a uniform shrinkage section, and then the tobacco embryo shaping groove of the shaper is correspondingly set to include an equal diameter area and a uniform shrinkage area, the groove width of the equal diameter area is the same, and the groove width of the uniform shrinkage area decreases uniformly from one end connected to the equal diameter area to the other end. After pressing, the uniform shrinkage area is pressed to form a "high-speed rail type" head. Since the bottom surface of the tobacco embryo shaping groove is an arc surface, the "high-speed rail type" head with uniformly reduced width (the groove width of the uniform shrinkage area is uniformly reduced from one end connected to the equal diameter area to the other end) can smoothly transition to the equal-width "high-speed rail type" body. After the mold upper cover and the mold base are covered, the pressing plate arranged on the mold upper cover is embedded in the tobacco embryo shaping groove to press the tobacco embryo. After pressing, the periphery of the pressing plate will form traces on the surface of the tobacco embryo, and these traces cleverly become the bottom edge of the "high-speed rail" shape. After the tobacco embryo expands and deforms, the bottom surface of the "high-speed rail"-shaped tobacco embryo is a curved surface, which prevents the cigar from being too angular and improves the sensory experience of smoking. The present invention transforms the unfavorable factor of "tobacco embryo expansion" in actual production into a favorable factor of the present invention, which can effectively solve the problem and reduce the extra steps of processing the appearance of the tobacco embryo in the present invention.

[0023] 3. The present invention sets the length of the uniform shrinkage zone to 1 / 4 to 1 / 2 of the length of the equal diameter zone, so that the length of the diameter change section of the finished "high-speed rail type" cigar after shaping and rolling is set to 1 / 4 to 1 / 2 of the length of the diameter constant section. The cigar changes from thick to thin in the middle and rear sections and tightens evenly, which can effectively increase the smoke concentration, highlight the main aroma, give more changes to the sensory experience of the cigarette, and improve the smoking quality.

DETAILED DESCRIPTION

[0026] The present invention will be further described below in conjunction with embodiments. Those of ordinary skill in the art will be able to implement the present invention based on these descriptions. In addition, the embodiments of the present invention involved in the following description are generally only embodiments of a part of the present invention, rather than all embodiments. Therefore, based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative work should belong to the scope of protection of the present invention.

[0027] Overall embodiment A method for rolling a "high-speed rail type" cigar 1 is provided, wherein the "high-speed rail type" cigar is Figure 1 As shown, the rolling method includes the following steps S1 to S3: Step S1: providing a cigar embryo, the embryo being as follows: Figure 2 As shown, it includes a connected equal diameter section A and a uniformly contracted section B, wherein the equal diameter sections have the same diameter, and the diameter of the uniformly contracted section decreases uniformly from one end connected to the equal diameter section to the other end. Figure 3 The tobacco embryo shown.

[0028] Step S2: providing a shaping device for shaping the tobacco embryos provided in step S1, such as Figures 4 to 8 As shown: The shaping device comprises a mold upper cover 2 and a mold base 3, and the mold upper cover 2 and the mold base 3 are covered to shape the cigarette embryo. Figure 4 The figure is a schematic diagram of the structure after the mold cover and the mold base are covered. Figure 7 It is a schematic diagram of the side view structure after the mold cover and the mold base are covered.

[0029] like Figure 5 As shown, the mold base 3 includes a cigarette embryo shaping groove 301, and the bottom surface of the cigarette embryo shaping groove is a curved surface; Figure 6 As shown, the tobacco embryo shaping groove includes a connected equal diameter area C and a uniform shrinkage area D, which are respectively used to accommodate the equal diameter section A and the uniform shrinkage section B of the tobacco embryo, the groove widths of the equal diameter areas are the same, the groove depths of the equal diameter areas are the same, the groove width of the uniform shrinkage area decreases uniformly from one end connected to the equal diameter area to the other end, and the groove depth of the uniform shrinkage area decreases uniformly from one end connected to the equal diameter area to the other end.

[0030] The mold upper cover 2 includes a pressing plate 201, which is embedded in the cigarette embryo shaping groove to press the cigarette embryo. The embedding can be understood as the width of the pressing plate being adapted to the groove width, so that it can just fit into the cigarette embryo shaping groove. Figure 8 As shown, Figure 8 This is a side view of the mold cover.

[0031] Step S3: placing the cigarette embryos provided in step S1 into the cigarette embryo shaping grooves 301 provided in step S2, closing the mold upper cover 2 and the mold base 3, and pressing and shaping.

[0032] The existing cigar rolling method requires frequent flipping to make the tobacco embryos evenly stressed. At the same time, insufficient flipping or improper flipping time control can easily cause indentation. For example, when the researchers of the present invention repeatedly applied for Example 1 of a cigar rolling method disclosed in the patent with the publication number CN113679093A, they found that if the mold is opened and the first cigar is rotated every 8 hours during the shaping process, the shaped cigar will have the following Fig. 9 Indentation shown.

[0033] In order to solve the flipping problem in the shaping process of cigar rolling, the present invention designs the cigar into a "high-speed rail shape" through the design of special-shaped cigar sticks, and provides a corresponding shaper to press the cigar embryo into a "high-speed rail shape". In the pressing process, an indentation is formed on the bottom edge of the "high-speed rail" shape. The formation of the indentation is cleverly utilized, so that the rolling method can avoid promoting uniform force through multiple flipping.

[0034] Specifically, the present invention rolls the tobacco embryo into a shape including an equal diameter section and a uniform shrinkage section, and then the tobacco embryo shaping groove of the shaper is correspondingly set to include an equal diameter area and a uniform shrinkage area, the groove width of the equal diameter area is the same, and the groove width of the uniform shrinkage area is uniformly reduced from one end connected to the equal diameter area to the other end. After pressing, the uniform shrinkage area is pressed to form a "high-speed rail type" head. Since the bottom surface of the tobacco embryo shaping groove is an arc surface, the "high-speed rail type" head with uniformly reduced width (the groove width of the uniform shrinkage area is uniformly reduced from one end connected to the equal diameter area to the other end) can smoothly transition to the equal-width "high-speed rail type" body. After the mold upper cover and the mold base are covered, the pressing plate arranged on the mold upper cover is embedded in the tobacco embryo shaping groove to press the tobacco embryo. After pressing, the periphery of the pressing plate will form traces on the surface of the tobacco embryo, and these traces cleverly become the bottom edge of the "high-speed rail" shape. After the tobacco embryo expands and deforms, the bottom surface of the "high-speed rail" shaped tobacco embryo becomes an arc surface, which prevents the finished cigar from being too angular and improves the sensory experience of smoking.

[0035] The expansion and deformation of tobacco embryos is a common problem in the cigar rolling process. The cigar core is a whole piece of dry tobacco leaves rolled into a bundle, then wrapped with a binder, shaped, and then rolled with a wrapper. The cigar rolling process is generally carried out in an environment of about 24°C and 60% relative humidity. After rolling, it needs to be aged. The aging environment is about 21°C and 65% relative humidity. In the cigar rolling process, the moisture content of the cigar core is about 14.5%, the binder is about 20%, and the wrapper is about 30%. Tobacco leaves have strong hygroscopicity. The rolling process will involve the balance between different types of tobacco leaves, as well as the decrease in overall moisture due to environmental influences, and it is necessary to ensure that the moisture content of the final cigar product is about 14%. During the tobacco embryo shaping process, including after the wrapper is applied, the moisture content of the tobacco leaves will be lower than when rolling, and the cigarette will expand as a whole. During the implementation of the method, it was found that the expansion and deformation of the tobacco embryo has a greater impact on the "high-iron type" cigar with edges of the present invention. After the deformation, the bottom edge of the "high-iron type" will be severely stretched due to expansion, making the deformation problem obvious.

[0036] In order to solve the expansion problem in the cigar rolling process, as a preferred method of the above rolling method, the lower surface of the pressing plate is an arc surface, and the arc height of the arc surface is 0.8-1.2 mm. The arc height should be understood as the distance from the vertex of the arc to the connecting line of the two end points of the arc on the arc shown in the cross section of the arc surface, that is, Figure 7 The arc height h in .

[0037] As a preferred embodiment of the above rolling method, the mold upper cover 2 is provided with a positioning protrusion 202, and the mold base 3 is provided with a positioning cavity 302 for accommodating the positioning protrusion.

[0038] As a preferred embodiment of the above rolling method, the number of the positioning protrusions is at least 2.

[0039] After the mold cover and the mold base are closed, the positioning protrusion 202 is embedded in the positioning cavity 302. Due to the embedding and positioning effect of the positioning protrusion and the positioning cavity, the pressing plate arranged on the mold cover is not easy to move during the process of pressing the tobacco embryo to shape, which is conducive to uniform pressing force.

[0040] Further preferably, the number of the positioning protrusions is 3, which are arranged on both sides of the pressing protrusion.

[0041] The number of positioning protrusions should not be too many. If there are too many, the efficiency of inserting when closing the cover and taking out when opening the cover after shaping will be reduced; if the number of positioning protrusions is too small, the pressing stability is insufficient and the pressing force is prone to unevenness.

[0042] As a preferred embodiment of the above rolling method, the length of the uniform shrinkage zone is 1 / 4 to 1 / 2 of the length of the uniform diameter zone.

[0043] By setting the length of the uniform shrinkage zone to 1 / 4~1 / 2 of the length of the equal diameter zone, that is, the length of the diameter change section of the finished "high-speed rail type" cigar after shaping and rolling is set to 1 / 4~1 / 2 of the length of the diameter unchanged section, the cigar changes from thick to thin in the middle and rear sections and tightens evenly, which can effectively increase the smoke concentration, highlight the main aroma, give the cigarette sensory more changes, and improve the smoking quality.

[0044] More preferably, the length of the uniform shrinkage zone is 1 / 3 of the length of the equal diameter zone.

[0045] As a preferred embodiment of the above rolling method, the width of the cigarette embryo shaping groove is 0.4-0.6 mm smaller than the maximum diameter of the cigarette embryo. This size can ensure that the density and inhalation resistance of the cigarette embryo after pressing are appropriate. At the same time, the expansion deformation is small.

[0046] As a preferred embodiment of the above rolling method, after the mold upper cover and the mold base are closed, the distance from the lower surface of the pressing plate to the bottom surface of the cigarette embryo shaping groove is 0.4-0.6 mm smaller than the maximum diameter of the cigarette embryo. This size can make the density and inhalation resistance of the cigarette embryo appropriate after pressing. At the same time, the expansion deformation is small.

[0047] As a preferred embodiment of the above rolling method, the pressing time is not less than 5 hours.

[0048] As a preferred embodiment of the above rolling method, after the mold upper cover and the mold base are closed, both ends of the cigarette embryo shaping groove are connected to the air.

[0049] As a preferred embodiment of the above rolling method, the rolling method further comprises the following steps: After pressing and shaping, the tail of the tobacco embryo is cut under the condition that the mold cover and the mold base are closed.

[0050] The cutting of the tail of the tobacco embryo is adjusted to the shaping process, which ensures that the tail is full and filled, and avoids deformation of the tail caused by the cutting process.

[0051] Adding wrapper is the last step in rolling cigarettes. After the tobacco embryo is shaped, the starting rolling position of the wrapper tobacco leaves can be set to the flat position at the bottom of the cigarette in this embodiment.

[0052] The shape of a conventional cigar with a regular symmetrical structure has no effect on the position of the wrapper. The shape of the cigar in this embodiment is an irregular stacking structure, and the position of the wrapper is fixed to the bottom plane of the cigarette because the contact plane between the cigarette and the wrapper is the largest at this position, which is beneficial to better stress and stretching of the wrapper tobacco leaves during the wrapper application process.

[0053] Compared with the prior art, this embodiment has the following technical effects: (1) The existing cigar rolling method requires frequent flipping to make the tobacco embryos evenly stressed. At the same time, a small number of flipping or improper flipping time control can easily cause indentations. In order to solve the flipping problem in the shaping process of cigar rolling, the present invention designs the cigar into a "high-speed rail shape" through the design of special-shaped cigar sticks, and provides a corresponding shaper to press the cigar embryos into a "high-speed rail shape". In the pressing process, the pressing forms an indentation on the bottom edge of the "high-speed rail" shape. The formation of the indentation is cleverly utilized, so that the rolling method can avoid promoting uniform stress through multiple flipping.

[0054] (2) In this embodiment, the tobacco embryo is rolled into a shape including an equal diameter section and a uniform shrinkage section, and then the tobacco embryo shaping groove of the shaper is correspondingly set to include an equal diameter area and a uniform shrinkage area, the groove width of the equal diameter area is the same, and the groove width of the uniform shrinkage area decreases uniformly from one end connected to the equal diameter area to the other end. After pressing, the uniform shrinkage area is pressed to form a "high-speed rail type" head. Since the bottom surface of the tobacco embryo shaping groove is an arc surface, the "high-speed rail type" head with uniformly reduced width (the groove width of the uniform shrinkage area is uniformly reduced from one end connected to the equal diameter area to the other end) can smoothly transition to the equal-width "high-speed rail type" body. After the mold upper cover and the mold base are covered, the pressing plate set on the mold upper cover is embedded in the tobacco embryo shaping groove to press the tobacco embryo. After pressing, the periphery of the pressing plate will form traces on the surface of the tobacco embryo, and these traces cleverly become the bottom edge of the "high-speed rail" shape. After the tobacco embryo expands and deforms, the bottom surface of the "high-speed rail"-shaped tobacco embryo is a curved surface, which prevents the cigar from being too angular and improves the sensory experience of smoking. The present invention transforms the unfavorable factor of "tobacco embryo expansion" in actual production into a favorable factor of the present invention, which can effectively solve the problem and reduce the extra steps of processing the appearance of the tobacco embryo in the present invention.

[0055] (3) In this embodiment, by setting the length of the uniform shrinkage zone to 1 / 4 to 1 / 2 of the length of the uniform diameter zone, the length of the diameter change section of the finished "high-speed rail" cigar after shaping and rolling is set to 1 / 4 to 1 / 2 of the length of the diameter constant section. In the middle and rear sections of the cigar, the thickness of the cigar changes from thick to thin and is tightened evenly, which can effectively increase the smoke concentration, highlight the main aroma, give the cigarette more changes in sensory perception, and improve the smoking quality.

[0056] Example 1 A method for rolling a "high-speed rail type" cigar is provided, comprising the following steps S1 to S5: Step S1: providing a cigar embryo, the embryo being as follows: Figure 2 As shown, it includes a connected equal diameter section A and a uniformly contracted section B, the equal diameter sections have the same diameter, and the diameter of the uniformly contracted section decreases uniformly from one end connected to the equal diameter section to the other end.

[0057] Step S2: providing a shaping device for shaping the tobacco embryos provided in step S1, such as Figures 4 to 8 As shown: The shaping device comprises a mold upper cover 2 and a mold base 3, and the mold upper cover 2 and the mold base 3 are covered to shape the cigarette embryo. Figure 4 The figure is a schematic diagram of the structure after the mold cover and the mold base are covered. Figure 7 It is a schematic diagram of the side view structure after the mold cover and the mold base are covered.

[0058] like Figure 5 As shown, the mold base 3 includes a cigarette embryo shaping groove 301, and the bottom surface of the cigarette embryo shaping groove is a curved surface; Figure 6 As shown, the tobacco embryo shaping groove includes a connected equal diameter area C and a uniform shrinkage area D, which are used to accommodate the equal diameter section A and the uniform shrinkage section B of the tobacco embryo respectively. The groove widths of the equal diameter areas are the same, and the groove width of the tobacco embryo shaping groove is 0.4-0.6 mm smaller than the maximum diameter of the tobacco embryo. The groove depths of the equal diameter areas are the same, and the groove width of the uniform shrinkage area decreases uniformly from one end connected to the equal diameter area to the other end, and the groove depth of the uniform shrinkage area decreases uniformly from one end connected to the equal diameter area to the other end. The length of the uniform shrinkage area is 1 / 3 of the length of the equal diameter area, that is, the length of the uniform shrinkage section is 1 / 3 of the length of the equal diameter section.

[0059] The mold upper cover 2 includes a pressing plate 201, and the lower surface of the pressing plate is set to a curved surface, and the arc height of the curved surface is 0.8-1.2 mm, that is, Figure 7 The arc height h is 0.8-1.2 mm. The pressing plate is embedded in the tobacco embryo shaping groove to press the tobacco embryo. The embedding is understood as the width of the pressing plate being adapted to the groove width and just being able to fit into the tobacco embryo shaping groove. After the mold cover and the mold base are closed, the distance from the lower surface of the pressing plate to the bottom surface of the tobacco embryo shaping groove is 0.4-0.6 mm smaller than the maximum diameter of the tobacco embryo. At the same time, after the mold cover and the mold base are closed, the two ends of the tobacco embryo shaping groove are connected to the air.

[0060] The mold upper cover 2 is provided with a positioning protrusion 202, and the mold base 3 is provided with a positioning cavity 302 for accommodating the positioning protrusion. The number of the positioning protrusions is 3, which are arranged on both sides of the pressing protrusion.
