[0002] The sealing machine is the last step in sealing the packaging tape during product processing. It can ensure the sealing of the packaging bag, ensure that the product is well preserved in the packaging bag, and is not prone to air leakage that may cause product deterioration or leakage.

[0003] For example, the patent with publication number CN106114992B discloses a sealing machine, in which the driven wheel mechanism of the sealing machine can facilitate the user to quickly slide the adjustment seat in the horizontal direction through the adjustment seat passed through the long screw rod; the patent with publication number CN207998037U discloses a sealing machine for processing plastic packaging bags, including a sealing machine, a control switch, a rolling wheel, a rolling crawler, a conveyor belt and a fixed base, the control switch is arranged above the sealing machine, and the control switch is electrically connected to the sealing machine. The sealing machines described in the above two patents are both provided with a transmission mechanism, which makes the overall structure of the equipment more complicated and occupies a larger space, is not convenient to move, cannot be used in homes or shopping malls, and does not have a portable function. At the same time, the sealing machine disclosed in the patent with publication number CN207998037U has no protective cover, and cannot protect the corresponding structure on the sealing machine and the user when in use, which is prone to accidents. Although the patent with publication number CN106114992B has a protective cover, the protective cover is fixed by a magnetic sheet and a magnet, and cannot be fixed at a certain angle at will. The practicality is not high and still needs to be strengthened. Summary of the invention

[0004] The purpose of this application is to provide a small sealing machine that can solve the above problems.

[0005] The purpose of this application is to provide a small sealing machine, comprising:

[0006] The sealing machine body comprises a machine body and a protective cover arranged on the machine body;

[0007] A traction mechanism, which is arranged on the machine body and is used to traction the plastic packaging bag;

[0008] A forming mechanism, which is arranged on the machine body and is used for heating and cooling the sealing bag;

[0009] An embossing mechanism, which is arranged on the machine body and is used to roll out stripes on the plastic packaging bag, and comprises a first embossing wheel and a second embossing wheel which are arranged at intervals;

[0010] A tensioning mechanism, which is arranged on the machine body and connected to the traction mechanism, and is used to adjust the tension of the traction mechanism;

[0011] Wherein, the cooling structure is located between the embossing mechanism and the heating structure, and a touch control screen is also provided on the machine body.

[0012] The above-mentioned small sealing machine can be used to seal plastic packaging bags. A power interface is provided on one side of the machine body. When the power interface is connected to power, the electric heating element generates heat, causing the first heating block and the second heating block to heat up rapidly. The temperature is adjusted to the required temperature through the plus and minus keys on the touch screen. Then the staff manually sends the sealing part of the plastic packaging bag between the running first sealing belt and the second sealing belt. The sealing part of the plastic bag is sent to the heating structure under the clamping of the first sealing belt and the second sealing belt. The plastic film is softened by heat and pressed and bonded. The plastic sealing part is sent to the cooling structure under the clamping of the first sealing belt and the second sealing belt to cool and shape. After shaping, it is rolled by the first embossing wheel and the second embossing wheel to roll out stripes or reticulations on the sealing part of the plastic bag. The entire equipment is configured with a touch screen, which is more convenient to operate. A protective cover is installed on the machine body to protect the machine body. The structural design of the whole machine is compact, occupies a small area, is relatively light, and has high practicality.

[0013] Furthermore, the shield includes an upper shield body and a lower shield body, and the upper shield body and the lower shield body are both connected to the body through a movable mechanism. When the upper shield body and the lower shield body are closed, they form a complete shield, and the upper shield body and the lower shield body are both provided with a plurality of reinforcing ribs.

[0014] By arranging an upper cover body and a lower cover body on the machine body, both the upper cover body and the lower cover body are connected to the machine body through a movable mechanism and can be folded up and down when in use. After the machine is turned on, the upper cover body and the lower cover body are closed to form a complete protective cover. When the first sealing belt and the second sealing belt need to be replaced, the upper cover body and the lower cover body can be folded, which is quick and convenient. The setting of the reinforcing ribs can improve the structural strength of the upper cover body and the lower cover body. In addition, the upper cover body and the lower cover body in the present application are made of pp plastic, have stable properties, and effectively extend the service life of the upper cover body and the lower cover body.

[0015] Further: the traction mechanism comprises:

[0016] A first traction structure comprises a first traction wheel, a second traction wheel, a third traction wheel and a fourth traction wheel which are arranged at intervals, and the first traction structure further comprises a first sealing belt;

[0017] The second traction structure comprises a fifth traction wheel, a sixth traction wheel and a seventh traction wheel which are arranged at intervals, and the second traction structure further comprises a second sealing belt;

[0018] The driving mechanism is connected to the first traction structure and the second traction structure and is used to drive the first traction structure and the second traction structure to operate.

[0019] The first traction structure and the second traction structure are respectively located on the upper and lower sides of the machine body. With the cooperation of the first traction wheel, the second traction wheel, the third traction wheel, the fourth traction wheel and the driving mechanism, the first sealing belt can be driven to operate. With the cooperation of the fifth traction wheel, the sixth traction wheel, the seventh traction wheel and the driving structure, the second sealing belt can be driven to operate. The cooperation and synchronous transportation of the first sealing belt and the second sealing belt can achieve the transportation of plastic packaging bags, so that the plastic packaging bags are heated by the heating structure, cooled and shaped by the cooling mechanism, and embossed with different patterns by the embossing mechanism. Among them, the driving part of the sealing machine of the present application is driven by a motor through gears to drive the first sealing belt and the second sealing belt to operate.

[0020] Furthermore, the forming mechanism comprises:

[0021] A heating structure, the heating structure comprising a first heating block and a second heating block arranged at an interval, the second heating block being mounted on the machine body through a fixing member;

[0022] A cooling structure, the cooling structure comprising a first cooling block and a second cooling block arranged at intervals and a fan arranged on the machine body, the first cooling block and the second cooling block are both provided with ventilation holes, and the second cooling block is mounted on the machine body through a fixing member;

[0023] An adjusting mechanism, which is arranged on both the heating structure and the cooling structure, and is used to adjust the positions of the heating structure and the cooling structure;

[0024] The heating structure and the cooling structure are located between the first traction structure and the second traction structure, and the first traction structure and the second traction structure, the heating structure and the cooling structure cooperate to form a transmission gap.

[0025] A heating structure is provided, the heating structure includes a first heating block and a second heating block spaced apart in an upper and lower manner, and the second heating block is fixed to the machine body by a fixing part, which can fix the position of the second heating block, thereby supporting the second sealing belt. When the plastic packaging bag enters the instant heating structure, the first heating block and the second heating block that have generated heat through the electric heating element soften the seal of the plastic packaging bag, which is convenient for subsequent pressing. The position of the first heating block can be adjusted by an adjusting mechanism, which is convenient for heating and sealing, and convenient for the first heating block to support the first sealing belt.

[0026] At the same time, by setting up a cooling mechanism, the plastic packaging bag that has been heated and sealed enters the cooling structure under the action of the traction mechanism. Under the action of the first cooling block and the second cooling block, the first sealing belt and the second sealing belt can be further supported. At the same time, when the fan and the ventilation hole are used in coordination, the heated plastic packaging bag can be quickly cooled, thereby playing a shaping role.

[0027] In addition, the heating structure and the cooling structure are located between the first traction structure and the second traction structure, and the first sealing belt and the second sealing belt, the heating structure and the cooling structure cooperate to form a conveying gap, and the plastic packaging bag passes through the conveying gap.

[0028] Furthermore, the adjustment mechanism includes a first adjustment structure and a second adjustment structure with the same structure, and the first adjustment structure and the second adjustment structure are respectively connected to the first heating block and the first cooling block. The first adjustment structure includes a fixed plate and a through groove symmetrically arranged on the fixed plate. Each through groove is provided with a guide rod connected to the first heating block, and each guide rod is sleeved with a first compression spring. An adjustment rod is also provided between the guide rods, one end of the adjustment rod is connected to the first heating block, and the other end of the adjustment rod is provided with an adjustment handle.

[0029] By providing the first adjustment structure and the second adjustment structure, the first heating block and the second heating block can be supported respectively, which can be more stable during use. When the staff does not apply pressure to the fixed plate, the fixed plate is pushed toward the sealing belt under the action of the first compression spring, thereby tensioning the sealing belt, which can effectively prevent the defect that the original sealing belt structure will loosen after long-term use; by providing an adjustment handle, by rotating the adjustment handle, since the fixed plate is installed on the machine body through a fixing part, the position of the first heating block and the first cooling block can be fine-tuned up and down by rotating the adjustment handle. In the case that the position of the first heating block and the first cooling block is offset after long-term use, the adjustment handle can be used to adjust them, so that the first heating block and the first cooling block remain level, thereby ensuring stable transportation of the equipment and keeping the seal flat during processing.

[0030] Furthermore, the tensioning mechanism comprises:

[0031] A first tensioning structure, the first tensioning structure comprising a first tensioning rod and a first tensioning disk connected to the first tensioning rod, the first tensioning disk being provided with a first tensioning wheel, and the first tensioning rod being provided with a torsion spring matched with the first tensioning disk;

[0032] A second tensioning structure; the second tensioning structure has the same structure as the first tensioning structure, the second tensioning structure comprises a second tensioning rod and a second tensioning disk connected to the second tensioning rod, the second tensioning disk is provided with a second tensioning wheel, and the second tensioning rod is provided with a torsion spring matched with the second tensioning disk;

[0033] Wherein, the third guide wheel is installed on the first tensioning rod, and the sixth guide wheel is installed on the second tensioning rod.

[0034] By setting the first tensioning structure and the second tensioning structure, the tensioning degree of the first sealing belt and the second sealing belt can be adjusted at any time. When in use, through the cooperation of the first tensioning rod, the first tensioning disk, the first tensioning wheel and the torsion spring, the first tensioning wheel on the first tensioning disk can maintain pressure in the direction of the first tensioning belt. If the tension of the first tensioning belt is insufficient, the first tensioning wheel will press the first sealing belt downward under the influence of the torsion spring, so that the first sealing belt maintains a certain tensioning degree. If the tension of the first sealing belt is too high, the first sealing belt will lift up the first tensioning wheel.

[0035] At the same time, when in use, through the cooperation of the second tensioning rod, the second tensioning disk, the second tensioning wheel and the torsion spring, the second tensioning wheel on the second tensioning disk can maintain pressure in the direction of the second tensioning belt. If the tension of the second tensioning belt is insufficient, the second tensioning wheel will press up the second sealing belt under the influence of the torsion spring, so that the second sealing belt maintains a certain tension. If the tension of the second sealing belt is too high, the second sealing belt will lift up the second tensioning wheel.

[0036] Furthermore, the activity mechanism includes:

[0037] A flip structure, the flip structure comprising a first support plate and a second support plate respectively mounted on the machine body and the upper cover body, the first support plate being provided with a rotating frame, and the second support plate being provided with a rotating shaft rotatably connected to the rotating frame;

[0038] A limiting structure, the limiting structure comprising a limiting plate and a first slide groove and a second slide groove symmetrically arranged on both sides of the limiting plate, an adjusting groove is arranged between the first slide groove and the second slide groove, a first slider and a second slider are symmetrically arranged in the adjusting groove, a first connecting rod and a second connecting rod are hinged on the first slider and the second slider respectively, and a first damper is arranged between the first slider and the second slider;

[0039] A linkage structure, wherein the linkage structure comprises an arc-shaped slide groove arranged on the rotating shaft, and the first connecting rod and the second connecting rod are both provided with a linkage rod matched with the arc-shaped slide groove, and one end of the linkage rod extends into the arc-shaped slide groove;

[0040] Wherein, the first connecting rod and the second connecting rod are both provided with a fine-tuning structure on one end away from the first sliding block and the second sliding block.

[0041] When the upper cover body and the lower cover body are flipped, the flipping process can be made more stable by setting a movable mechanism. When flipping, the angle between the first support plate located on the machine body and the second support plate located on the upper cover body gradually increases from 0° to 90°. During the change of the angle, the second support plate drives the rotating shaft to rotate on the rotating frame. During the rotation process, the first connecting rod and the linkage rod on the second connecting rod shorten the distance between the first connecting rod and the second connecting rod as the rotation angle increases, thereby driving the distance between the first slider and the second slider to decrease, so that the first damper is compressed. When the upper cover body and the lower cover body are closed, When the cover body is opened and closed, the angle between the first support plate and the second support plate gradually decreases. In the process of angle change, the linkage rod on the first connecting rod and the second connecting rod makes the distance between the first connecting rod and the second connecting rod gradually increase as the rotation angle decreases. At this time, the distance between the first slider and the second slider gradually increases, so that the first damper is stretched. Therefore, in the process of opening and closing the upper cover body and the lower cover body, the opening and closing are more stable through the expansion and contraction of the first damper. At the same time, when the angle between the first support plate and the second support plate changes, the fine-tuning mechanism can further improve the damping effect.

[0042] Furthermore, the fine-tuning structure includes:

[0043] A linkage block, wherein the linkage block is disposed in the first slide groove and can slide in the first slide groove, and the top of the linkage block is hinged to the first connecting rod;

[0044] A second damper, wherein the second damper is disposed in the first slide groove and a telescopic end of the second damper is connected to the linkage block;

[0045] A second compression spring is arranged in the first slide slot, one end of the second compression spring is connected to the first slide slot, and the other end is connected to the linkage block;

[0046] Wherein, the linkage block is provided with a hook, and the second compression spring is connected to the hook.

[0047] When the angle between the first support plate and the second support plate gradually increases, the linkage block drives the second damper to stretch, thereby playing a damping and buffering role. During the movement of the linkage block, the second compression spring is stretched, further improving the damping and buffering effect. When the angle between the first support plate and the second support plate gradually decreases, the linkage block drives the second damper to compress, thereby playing a damping and buffering effect. During the movement of the linkage block, the second compression spring is compressed, further improving the damping and buffering effect. At the same time, the first sliding block and the second sliding block are both connected with a fine-tuning structure. With the cooperation of the fine-tuning structure and the movable mechanism, the stability of the mountain cover body and the lower cover body when opening and closing can be effectively guaranteed, and the upper cover body and the lower cover body can be stopped at a certain angle at will, thereby preventing the upper cover body and the lower cover body from automatically closing when they are not fixed after opening, protecting the user's safety and having higher practicality.

[0048] The beneficial effects of this application are:

[0049] 1. The above-mentioned small sealing machine can be used to seal plastic packaging bags. When the power interface is connected to the power supply, the first heating block and the second heating block are heated rapidly, and the required temperature is adjusted by the plus and minus keys on the touch screen. Then, the sealing part of the plastic packaging bag is sent between the first sealing belt and the second sealing belt. Under the influence of the heating structure, the plastic film is softened by heat and pressed and bonded. Then, it is cooled and shaped under the influence of the cooling structure. After shaping, it is rolled by the first embossing wheel and the second embossing wheel to roll out stripes or reticulations on the sealing part of the plastic bag. The whole device adopts a touch screen configuration, which is more convenient to operate. A protective cover is installed on the machine body to protect the machine body. The structure design of the whole machine is compact, small in area, relatively light, and highly practical.

[0050] 2. When the upper cover and the lower cover are flipped, the angle between the first support plate and the second support plate gradually increases, and the second support plate drives the rotating shaft to rotate on the rotating frame. As the rotation angle increases, the distance between the first connecting rod and the second connecting rod becomes shorter, thereby driving the distance between the first slider and the second slider to become smaller, so that the first damper is compressed. When the upper cover and the lower cover are closed, the angle between the first support plate and the second support plate gradually decreases, and the distance between the first connecting rod and the second connecting rod gradually increases as the rotation angle decreases. At this time, the distance between the first slider and the second slider gradually increases, so that the first damper is stretched. Therefore, in the process of opening and closing the upper cover and the lower cover, the expansion and contraction of the first damper make the opening and closing more stable. At the same time, when the angle between the first support plate and the second support plate changes, the fine-tuning mechanism can further improve the damping effect.

[0051] 3. When the angle between the first support plate and the second support plate gradually increases, the linkage block drives the second damper to stretch, thereby playing a damping and buffering role. During the movement of the linkage block, the second compression spring is stretched, further improving the damping and buffering effect. When the angle between the first support plate and the second support plate gradually decreases, the linkage block drives the second damper to compress, thereby playing a damping and buffering effect. During the movement of the linkage block, the second compression spring is compressed, further improving the damping and buffering effect. At the same time, the first sliding block and the second sliding block are both connected with a fine-tuning structure. With the practical cooperation of the fine-tuning structure and the movable mechanism, the stability of the mountain cover body and the lower cover body when opening and closing can be effectively guaranteed, and the upper cover body and the lower cover body can be stopped at a certain angle at will, thereby preventing the upper cover body and the lower cover body from automatically closing when they are not fixed after opening, protecting the user's safety and having higher practicality.

[0089] In the embodiment of the present application, a heating structure 310 is provided, and the heating structure 310 includes a first heating block 311 and a second heating block 312 which are spaced apart from each other in an upper and lower direction. The second heating block 312 is fixed to the body 100 by a fixing member, which can fix the position of the second heating block 312, thereby supporting the second sealing belt 224.

[0094] like Figure 4 As shown, the adjustment mechanism 350 includes a first adjustment structure and a second adjustment structure with the same structure. The first adjustment structure and the second adjustment structure are respectively connected to the first heating block 311 and the first cooling block 321. The first adjustment structure includes a fixed plate 351 and a through groove symmetrically arranged on the fixed plate 351. Each through groove is provided with a guide rod 353 connected to the first heating block 311. Each guide rod 353 is sleeved with a first compression spring 354. An adjustment rod 355 is also provided between the guide rods 353. One end of the adjustment rod 355 is connected to the first heating block 311, and the other end of the adjustment rod 355 is provided with an adjustment handle 356.

[0095] In the embodiment of the present application, by providing the first adjustment structure and the second adjustment structure, the first heating block 311 and the second heating block 312 can be supported respectively, which can be more stable during use. When the staff does not apply pressure to the fixing plate 351, the fixing plate 351 is pushed toward the sealing belt under the action of the first compression spring 354, so that the sealing belt is tensioned, which can effectively prevent the defect that the original sealing belt structure will loosen after long-term use; by providing the adjustment handle 356, by rotating the adjustment handle 356, since the fixing plate 351 is installed on the body 100 through the fixing member, the position of the first heating block 311 and the first cooling block 321 can be fine-tuned up and down by rotating the adjustment handle 356.

[0096] Embodiment 6:

[0097] An embodiment of the present application provides a small sealing machine. In addition to the above-mentioned technical features, the small sealing machine of the embodiment of the present application also includes the following technical features.

[0098] like Figure 3 As shown, the tensioning mechanism 500 comprises;

[0099] A first tensioning structure 510, the first tensioning structure 510 comprises a first tensioning rod 511 and a first tensioning disc 512 connected to the first tensioning rod 511, a first tensioning wheel 513 is provided on the first tensioning disc 512, and a torsion spring 514 matched with the first tensioning disc 512 is provided on the first tensioning rod 511;

[0100] The second tensioning structure 520; the second tensioning structure 520 has the same structure as the first tensioning structure 510, and includes a second tensioning rod 521 and a second tensioning disc 522 connected to the second tensioning rod 521, a second tensioning wheel 523 is provided on the second tensioning disc 522, and a torsion spring 514 matched with the second tensioning disc 522 is provided on the second tensioning rod 521;

[0101] The third guide wheel is installed on the first tensioning rod 511 , and the sixth guide wheel is installed on the second tensioning rod 521 .

When in use, through the cooperation of the first tensioning rod 511, the first tensioning disk 512, the first tensioning wheel 513, and the torsion spring 514, the first tensioning wheel 513 on the first tensioning disk 512 can maintain pressure in the direction of the first tensioning belt. If the tension of the first tensioning belt is insufficient, the first tensioning wheel 513 presses down the first sealing belt 215 under the influence of the torsion spring 514, so that the first sealing belt 215 maintains a certain tensioning degree. If the tension of the first sealing belt 215 is too high, the first sealing belt 215 will lift up the first tensioning wheel 513.

[0103] At the same time, when in use, through the cooperation of the second tensioning rod 521, the second tensioning disk 522, the second tensioning wheel 523, and the torsion spring 514, the second tensioning wheel 523 on the second tensioning disk 522 can maintain pressure in the direction of the second tensioning belt. If the tension of the second tensioning belt is insufficient, the second tensioning wheel 523 will press up the second sealing belt 224 under the influence of the torsion spring 514, so that the second sealing belt 224 maintains a certain tension. If the tension of the second sealing belt 224 is too high, the second sealing belt 224 will lift up the second tensioning wheel 523.

[0104] Embodiment 7:

[0105] An embodiment of the present application provides a small sealing machine. In addition to the above-mentioned technical features, the small sealing machine of the embodiment of the present application also includes the following technical features.

[0106] like Figure 5 As shown, the movable mechanism 600 includes:

[0107] The flip structure 610 includes a first support plate 611 and a second support plate 612 respectively mounted on the machine body 100 and the upper cover 110. The first support plate 611 is provided with a rotating frame 613, and the second support plate 612 is provided with a rotating shaft 614 rotatably connected to the rotating frame 613;

[0108] The limiting structure 620 includes a limiting plate 621 and a first slide groove 622 and a second slide groove 623 symmetrically arranged on both sides of the limiting plate 621. An adjusting groove 624 is arranged between the first slide groove 622 and the second slide groove 623. A first slider 625 and a second slider 626 are symmetrically arranged in the adjusting groove 624. A first connecting rod 627 and a second connecting rod 628 are hinged to the first slider 625 and the second slider 626, respectively. A first damper 629 is arranged between the first slider 625 and the second slider 626.

[0109] The linkage structure 630 includes an arc-shaped slide groove 631 disposed on the rotating shaft 614. The first link 627 and the second link 628 are both provided with a linkage rod 632 that cooperates with the arc-shaped slide groove 631. One end of the linkage rod 632 extends into the arc-shaped slide groove 631.

[0110] Wherein, a fine-tuning structure 700 is disposed on one end of the first connecting rod 627 and the second connecting rod 628 away from the first sliding block 625 and the second sliding block 626 .

[0111] In the embodiment of the present application, when the upper cover body 110 and the lower cover body 120 are flipped, the movable mechanism 600 is provided to make the flipping process more stable. When flipping, the angle between the first support plate 611 located on the body 100 and the second support plate 612 located on the upper cover body 110 gradually increases from 0° to 90°. During the change of the angle, the second support plate 612 drives the rotating shaft 614 to rotate on the rotating frame 613. During the rotation process, the first connecting rod 627 and the linkage rod 632 on the second connecting rod 628 shorten the distance between the first connecting rod 627 and the second connecting rod 628 as the rotation angle increases, thereby driving the distance between the first slider 625 and the second slider 626 to decrease, so that the first damper 629 is compressed. When the upper cover body 110 and the lower cover body 120 are closed, the angle between the first support plate 611 and the second support plate 612 gradually decreases. During the angle change, the linkage rod 632 on the first link 627 and the second link 628 gradually increases as the rotation angle decreases. At this time, the distance between the first slider 625 and the second slider 626 gradually increases, so that the first damper 629 is stretched. Therefore, in the process of opening and closing the upper cover body 110 and the lower cover body 120, the opening and closing are more stable through the expansion and contraction of the first damper 629. At the same time, when the angle between the first support plate 611 and the second support plate 612 changes, the fine-tuning mechanism setting can further improve the damping effect.

[0112] Embodiment 8:

[0113] An embodiment of the present application provides a small sealing machine. In addition to the above-mentioned technical features, the small sealing machine of the embodiment of the present application also includes the following technical features.

[0115] A linkage block 710, which is disposed in the first slide groove 622 and can slide in the first slide groove 622, and the top of the linkage block 710 is hinged to the first connecting rod 627;

[0116] A second damper 720, the second damper 720 is disposed in the first slide groove 622 and a telescopic end of the second damper 720 is connected to the linkage block 710;

[0117] A second compression spring 740 is disposed in the first slide groove 622, one end of the second compression spring 740 is connected to the first slide groove 622, and the other end is connected to the linkage block 710;

[0118] The linkage block 710 is provided with a hook 750 , and the second compression spring 740 is connected to the hook 750 .

[0119] In the embodiment of the present application, when the angle between the first support plate 611 and the second support plate 612 gradually increases, the linkage block 710 drives the second damper 720 to stretch, thereby playing a damping and buffering role. During the movement of the linkage block 710, the second compression spring 740 is stretched to further improve the damping and buffering effect. When the angle between the first support plate 611 and the second support plate 612 gradually decreases, the linkage block 710 drives the second damper 720 to compress, thereby playing a damping and buffering effect. During the movement of the linkage block 710, the second compression spring 740 is stretched to further improve the damping and buffering effect. The two compression springs 740 are compressed internally, which further improves the damping effect. At the same time, the first sliding block and the second sliding block are connected with a fine-tuning structure 700. With the cooperation of the fine-tuning structure 700 and the movable mechanism 600, the stability of the upper cover body 110 and the lower cover body 120 when opening and closing can be effectively guaranteed, and the upper cover body 110 and the lower cover body 120 can be stopped at a certain angle at will, thereby preventing the upper cover body 110 and the lower cover body 120 from automatically closing after being not fixed when opened, thereby protecting the user's safety and being more practical.
