[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0033] like Figures 1 to 7 As shown, a mobile communication device according to the present invention comprises:

[0034] Body 1;

[0035] A pressing plate 2, the pressing plate 2 is hingedly mounted on the side wall of the fuselage 1, a hinge shaft 21 is installed at the hinge between the pressing plate 2 and the fuselage 1, a movable groove 22 is opened on the side of the pressing plate 2 close to the fuselage 1, a movable plate 23 is slidably mounted in the movable groove 22, and a first airbag 24 is fixedly mounted on the side of the pressing plate 2 away from the fuselage 1, and the first airbag 24 is located at the upper part of the pressing plate 2;

[0036] A card plate 3, the card plate 3 has an arc-shaped cross section, the card plate 3 is fixedly mounted on the upper end of the movable plate 23, a support plate 210 is mounted on the upper end of the movable plate 23, the support plate 210 has an inverted "L"-shaped cross section, a wedge block 33 is mounted on the support plate 210 close to the upper end of the fuselage 1, and the tip of the wedge block 33 is aligned with the gap between the hinge shaft 21 and the fuselage 1;

[0037] The second airbag 31 is fixedly mounted on the side of the pressing plate 2 close to the fuselage 1. The second airbag 31 is connected to the first airbag 24 via the first tube 32. The first tube 32 is located inside the pressing plate 2. The second airbag 31 contacts the upper surface of the support plate 210 after being inflated. The second airbag 31 does not contact the wedge block 33.

[0038] During operation, when the body 1 needs to be placed in the pocket, a force is applied to the upper part of the pressing plate 2, and the direction of the force is toward the body 1. Since the pressing plate 2 is connected to the body 1 through the hinge shaft 21, the pressing plate 2 rotates clockwise with the hinge shaft 21 as the center, and the opening between the pressing plate 2 and the body 1 becomes larger. At this time, the pocket enters the gap between the pressing plate 2 and the body 1 through the opening, and the body 1 is placed downward along the pocket. The pocket moves upward relative to the pressing plate 2 and the body 1. There is friction between the movable plate 23 and the movable groove 22. The movable plate 23 will slide in the movable groove 22 only when it is acted upon by an external force. When the pocket touches the card plate 3 on the movable plate 23, the top edge of the pocket pushes the card plate 3 to move upward. The card plate 3 is fixedly connected to the movable plate 23, and the movable plate 23 also moves with the card plate 3. The pressing plate 2 moves upward along the movable groove 22. When the wedge block 33 contacts the hinge shaft 21, the force on the upper part of the pressing plate 2 is released. At this time, the pressing plate 2 rotates counterclockwise with the hinge shaft 21 as the center. The hinge shaft 21 brings the wedge block 33 into the gap between the hinge shaft 21 and the fuselage 1 and clamps it. The opening between the pressing plate 2 and the fuselage 1 becomes smaller. The bottom of the pressing plate 2 and the fuselage 1 clamp the pocket. When the worker bends down, the fuselage 1 placed on the pocket turns over. At this time, the fuselage 1 falls under the action of gravity. An inverted "L"-shaped support plate 210 is installed on the upper end of the movable plate 23. A wedge block 33 is fixedly installed on the support plate 210. As the movable plate 23 moves upward driven by the pocket, the wedge block 33 on the support plate 210 also moves upward and is clamped between the hinge shaft 21 and the fuselage 1. When the fuselage 1 is turned over, the movable plate 23 is not affected by external forces other than static friction, and is not easy to slide. The position of the card plate 3 and the support plate 210 on the movable plate 23 relative to the hinge shaft 21 remains unchanged, the position of the wedge block 33 relative to the hinge shaft 21 remains unchanged, the hinge shaft 21 does not rotate, and the pressing plate 2 does not rotate either, so that the opening between the pressing plate 2 and the fuselage 1 will not become larger, so that the fuselage 1 is stably clamped on the pocket, so that when the fuselage 1 is turned over, the fuselage 1 is not easy to fall. When the fuselage 1 needs to be taken out, a force is applied to the upper part of the pressing plate 2, and the direction of the force is toward the fuselage 1. At this time, the No. 1 airbag 24 is squeezed, the volume of the No. 1 airbag 24 becomes smaller, and the internal gas pressure becomes larger. Since the No. 1 airbag 24 is connected to the No. 2 airbag 31 through the No. 1 pipe 32, the No. 1 airbag 24 is connected to the No. 2 airbag 31 through the No. 1 pipe 32. The high-pressure gas in the bag 24 enters the No. 2 airbag 31 through the No. 1 pipe 32. At this time, the gas inside the No. 2 airbag 31 increases, the pressure becomes greater, the No. 2 airbag 31 expands and contacts the support plate 210, and the support plate 210 is squeezed by the No. 2 airbag 31 and moves downward, thereby driving the wedge block 33 to move downward, so that the wedge block 33 is separated from the hinge shaft 21, and the hinge shaft 21 is not restricted by the wedge block 33 and rotates clockwise. The movable plate 23 fixedly connected to the support plate 210 moves downward along the movable groove 22 under the action of the support plate 210, and the card plate 3 fixedly connected to the movable plate 23 moves downward and squeezes the pocket to move downward. Since the upper part of the pressing plate 2 is subjected to the force, the pressing plate 2 rotates clockwise with the hinge shaft 21 as the center, and the opening between the pressing plate 2 and the fuselage 1 becomes larger.At this time, the pressing plate 2 and the body 1 are no longer in contact with the pocket, and the body 1 is taken out of the pocket. Similarly, when the body is just inserted into the pocket, the user presses the pressing plate 2. At this time, the No. 1 airbag 24 and the No. 2 airbag 31 return to their original state, and the support plate 210 is no longer squeezed by the No. 2 airbag 31. After that, the body put into the pocket falls down under the action of gravity, and the movable plate 23 moves upward through the clamping plate 3, and then the support plate 210 drives the wedge block 33 to move upward and contact the hinge shaft 21, thereby restricting the hinge shaft 21.

[0039] As an embodiment of the present invention, an elastic steel wire 35 is vertically installed on the side of the movable plate 23 facing the fuselage 1, and the elastic steel wire 35 is located at the lower end of the movable plate 23. A rubber spring 29 is fixedly installed on the side of the movable plate 23 facing the fuselage 1, and the rubber spring 29 covers the area where the elastic steel wire 35 is located. The surface of the rubber spring 29 is rough and evenly provided with through holes, and the through holes correspond one to one with the elastic steel wire 35.

[0040] During work, when the worker bends over, the fuselage 1 placed on the pocket turns over. At this time, the fuselage 1 slides down along the pocket under the action of gravity. A rubber spring 29 is installed at the lower end of the movable plate 23, and the surface of the rubber spring 29 is rough, which increases the contact area between the pressing plate 2 and the pocket, so that the friction between the pressing plate 2 and the pocket is increased, thereby offsetting part of the gravity effect. An elastic steel wire 35 is vertically installed on the side of the movable plate 23 facing the fuselage 1, and the rubber spring 29 covers the area where the elastic steel wire 35 is located. The surface of the rubber spring 29 is rough and Through holes are evenly provided, and there is a one-to-one correspondence between the through holes and the elastic steel wires 35. At the same time, the through holes can be obtained by directly piercing the rubber spring sheet 29 with the elastic steel wires 35 during the production process. When the bottom of the pressing plate 2 and the body 1 clamp the pocket, the rubber spring sheet 29 is squeezed, and the elastic steel wire 35 is inserted into the pocket fabric in contact with the rubber spring sheet 29 through the through holes on the rubber spring sheet 29, so that the pocket is not separated from the pressing plate 2, so that when the body 1 placed on the pocket is turned over, the body 1 is firmly clamped on the pocket and does not fall off.

[0041] As an embodiment of the present invention, the middle position of the hinge shaft 21 is a spline, and the wedge block 33 has a locking groove on a side close to the hinge shaft 21, and the locking groove is engaged with the spline.

[0042] During operation, in order to make the wedge block 33 and the hinge shaft 21 more tightly connected and prevent the fuselage 1 from falling off when it is flipped, a spline is arranged at the center of the hinge shaft 21, and a locking groove is arranged on a side of the wedge block 33 close to the hinge shaft 21. When the wedge block 33 contacts the hinge shaft 21, the spline engages with the locking groove, so that the wedge block 33 prevents the hinge shaft 21 from rotating clockwise and does not slip. Therefore, when the fuselage 1 is flipped, the wedge block 33 and the hinge shaft 21 are prevented from slipping, and the hinge shaft 21 moves clockwise without being hindered by the wedge block 33, causing the opening between the pressing plate 2 and the fuselage 1 to become larger, thereby causing the pocket to be not pressed by the pressing plate 2 and the fuselage 1, causing the fuselage 1 to fall off when it is flipped.

[0043] As an implementation mode of the present invention, an elastic sheet 34 is installed at one end of the card board 3 close to the fuselage 1 , and the end of the elastic sheet 34 away from the card board 3 is closely attached to the back of the fuselage 1 .

[0044] During operation, since the width of the card plate 3 does not change with the change of the size of the opening between the pressing plate 2 and the fuselage 1, when the opening becomes larger and the pocket enters the gap between the fuselage 1 and the pressing plate 2, since the width of the card plate 3 does not change, the end of the card plate 3 close to the fuselage 1 is away from the fuselage 1, so that a gap is generated between the card plate 3 and the fuselage 1. When the pocket is placed on the fuselage 1, the fabric at the top edge of the pocket directly passes through the gap between the card plate 3 and the fuselage 1 without contacting the card plate 3, so that the movable plate 23 cannot move upward under the action of the card plate 3, and when the pressing plate 2 is not acted upon by force, the fabric at the top edge of the pocket exists between the card plate 3 and the fuselage 1. When the pressing plate 2 is pressed, the fabric at the top edge of the pocket is between the card plate 3 and the fuselage 1. When the force is removed, the pressing plate 2 moves to its original position. Due to the presence of the fabric at the top edge of the pocket between the card plate 3 and the fuselage 1, the extrusion force on the card plate 3 is too large, causing the card plate 3 to be damaged. By installing an elastic sheet 34 on the end of the card plate 3 close to the fuselage 1, and the end of the elastic sheet 34 away from the card plate 3 is always close to the back of the fuselage 1, the fabric at the top edge of the pocket is blocked by the elastic sheet 34 after entering the gap between the pressing plate 2 and the fuselage 1, and does not enter the gap between the card plate 3 and the fuselage 1. The fabric at the top edge of the pocket contacts the concave part of the card plate 3, and the fabric at the top edge of the pocket drives the card plate 3 and the movable plate 23 to move upward along the movable groove 22.

[0045] As an implementation mode of the present invention, evenly distributed elastic steel wires 35 are installed on a side of the cardboard 3 away from the second airbag 31 , and the elastic steel wires 35 are perpendicular to the tangent of the cardboard 3 .

[0046] During operation, when the fuselage 1 is put into the pocket, when the fuselage 1 is not perpendicular to the top edge of the pocket, the card plate 3 is not parallel to the top edge of the pocket, then the top edge of the pocket contacts one end of the card plate 3 and drives the movable plate 23 to move upward along the movable groove 22. When the force on the pressing plate 2 is removed, the fuselage 1 is clamped on the pocket at an angle. At this time, the fuselage 1 is unstable. When the pocket shakes, the fuselage 1 shakes left and right along the top edge of the pocket. The card plate 3 is arranged away from the second airbag 31 and is equipped with evenly distributed elastic steel wires 35. When the pocket contacts the card plate 3, the elastic steel wires 35 on the card plate 3 are inserted into the fabric at the top edge of the pocket, thereby fixing the pocket. When the pocket shakes, the fuselage 1 does not shake left and right, so that the fuselage 1 is stably installed on the pocket.

[0047] As an embodiment of the present invention, a fixed groove 25 is provided in a side of the movable groove 22 away from the fuselage 1, a deformable sheet 26 is installed in the fixed groove 25, the upper end of the deformable sheet 26 is fixedly installed on the upper end of the fixed groove 25, the lower end of the deformable sheet 26 slides freely in the fixed groove 25, and a rectangular hole 231 is provided on the movable plate 23, and the rectangular hole 231 is smaller than the opening size of the fixed groove 25.

[0048] During operation, when the movable plate 23 is located at the bottom of the movable groove 22, the rectangular hole 231 is located below the movable groove 22, and the protruding portion of the deformable sheet 26 cannot extend from the rectangular hole 231. At the same time, since the deformable sheet 26 is a thin steel sheet with elasticity made of spring steel, the deformable sheet 26 in the fixed groove 25 is squeezed by the movable plate 23, and the lower end of the deformable sheet 26 slides downward in the fixed groove 25. When the movable plate 23 moves upward along the movable groove 22, the rectangular hole 231 moves upward. The rectangular hole 231 and the movable slot 22 move, and the rectangular hole 231 contacts the deformable sheet 26. The protruding portion of the deformable sheet 26 gradually extends out of the rectangular hole 231. Therefore, the protruding portion of the deformable sheet 26 moves along the rectangular hole 231 toward the fuselage 1. Since the upper end of the deformable sheet 26 is fixed to the upper end of the fixing slot 25, the lower end of the deformable sheet 26 slides freely in the fixing slot 25. Therefore, when the protruding portion of the deformable sheet 26 moves along the rectangular hole 231 toward the fuselage 1, When the pocket is moved, the lower end of the deformable sheet 26 moves upward, and when the raised portion on the deformable sheet 26 moves toward the fuselage 1, the pocket enters the gap between the pressing plate 2 and the fuselage 1. As the raised portion on the deformable sheet 26 continues to move toward the fuselage 1, the raised portion on the deformable sheet 26 contacts the pocket and squeezes the pocket with the fuselage 1, thereby fixing the pocket. When the fuselage 1 is turned over, the pocket and the pressing plate 2 have two force points, the deformable sheet 26 and the rubber spring sheet 29, so that the fuselage 1 does not fall when it is turned over. When moving downward, the rectangular hole 231 on the movable plate 23 squeezes the raised part on the deformation sheet 26, causing the lower end of the deformation sheet 26 to move downward, thereby increasing the distance between the upper end and the lower end of the deformation sheet 26, causing the raised part on the deformation sheet 26 to move toward the pressing plate 2, and finally causing the raised part on the deformation sheet 26 to be retracted from the rectangular hole 231. The entire deformation sheet 26 is located on the side of the movable plate 23 facing the fixed groove 25, and the raised part on the deformation sheet 26 does not contact the pocket. After that, the fuselage 1 is taken out of the pocket.

[0049] As an embodiment of the present invention, the back side of the body 1 has a groove 11;

[0050] During operation, by providing a groove 11 on the back of the fuselage 1, the raised part on the deformable sheet 26 and the fuselage 1 squeeze the pocket in the groove 11, thereby increasing the contact area between the pocket and the fuselage 1 and increasing the friction between the pocket and the fuselage 1. When the fuselage 1 is turned over, the fuselage 1 will not fall.

[0051] As an embodiment of the present invention, a rubber layer 12 is installed in the groove 11 , the rubber layer 12 is concave, and a short needle is installed in the rubber layer 12 .

[0052] During operation, a rubber layer 12 is installed in the groove 11. When the pocket is squeezed by the raised part on the deformation sheet 26 and the fuselage 1, the rubber layer 12 is acted upon by force, thereby causing the rubber layer 12 to deform. A short needle is installed in the rubber layer 12. After the rubber layer 12 is deformed, the short needle is exposed from the rubber layer 12, and the short needle contacts and inserts into the pocket, thereby fixing the pocket with the short needle. When the fuselage 1 is turned over, the fuselage 1 does not fall off.

[0053] As an embodiment of the present invention, a No. 3 airbag 27 is installed on the upper end of the pressing plate 2 close to the fuselage 1, and the No. 3 airbag 27 is connected to a No. 2 tube 28. The open end of the No. 2 tube 28 is in the fixing groove 25, and the open end of the No. 2 tube 28 does not contact the deformation plate 26.

[0054] During operation, a No. 3 airbag 27 is installed at the upper end of the pressing plate 2 close to the fuselage 1. When the pressing plate 2 is subjected to force, the upper end of the pressing plate 2 close to the fuselage 1 contacts the fuselage 1, the No. 3 airbag 27 is squeezed, and the gas inside the No. 3 airbag 27 is compressed. The gas is discharged through the No. 2 pipe 28 connected to the No. 3 airbag 27. Since the opening end of the No. 2 pipe 28 is in the fixed groove 25 and the opening end of the No. 2 pipe 28 does not contact the deformation sheet 26, the gas through the No. 2 pipe 28 blows air to the surface of the deformation sheet 26, so that the thread ends, dust and other debris attached to the deformation sheet 26 after the contact with the pocket are removed, thereby ensuring the normal movement of the lower end of the deformation sheet 26.

[0055] As an embodiment of the present invention, a rubber skin 4 is provided on the upper end of the pressing plate 2 , and the No. 1 airbag 24 and the No. 3 airbag 27 are wrapped by the rubber skin 4 .

[0056] During operation, when in use, the pressing plate 2 will be often pressed. After being pressed too much, the airbag No. 1 24 and the airbag No. 3 27 are prone to wear. The airbag No. 1 24 and the airbag No. 3 27 at the upper end of the pressing plate 2 are wrapped with a rubber skin 4, so that the airbag No. 1 24 and the airbag No. 3 27 will not directly contact the outside world, thereby protecting the airbag No. 1 24 and the airbag No. 3 27 from friction and wear. At the same time, by wrapping a layer of rubber skin 4 outside the airbag No. 1 24 and the airbag No. 3 27, the aesthetic effect of the pressing plate 2 is improved.

[0057] The specific workflow is as follows:

[0058] When the body 1 needs to be placed in a pocket, force is applied to the upper part of the pressing plate 2.The direction of the force is toward the fuselage 1. Since the pressing plate 2 is connected to the fuselage 1 through the hinge shaft 21, the pressing plate 2 rotates clockwise with the hinge shaft 21 as the center. The opening between the pressing plate 2 and the fuselage 1 becomes larger. At this time, the pocket enters the gap between the pressing plate 2 and the fuselage 1 through the opening, and the fuselage 1 is placed downward along the pocket. The pocket moves upward relative to the pressing plate 2 and the fuselage 1. There is friction between the movable plate 23 and the movable groove 22. The movable plate 23 will slide in the movable groove 22 only when it is subjected to external force. When the pocket touches the card plate 3 on the movable plate 23, the top edge of the pocket pushes the card plate 3 to move upward. The card plate 3 is fixedly connected to the movable plate 23, and the movable plate 23 also moves upward along the movable groove 22 with the card plate 3. When the wedge block 33 contacts the hinge shaft 21, The force on the upper part of the pressing plate 2 is released. At this time, the pressing plate 2 rotates counterclockwise with the hinge shaft 21 as the center. The hinge shaft 21 brings the wedge block 33 into the gap between the hinge shaft 21 and the fuselage 1 and clamps it. The opening between the pressing plate 2 and the fuselage 1 becomes smaller. The bottom of the pressing plate 2 and the fuselage 1 clamp the pocket. When the worker bends down, the fuselage 1 placed on the pocket flips over. At this time, the fuselage 1 falls under the action of gravity. An inverted "L"-shaped support plate 210 is installed on the upper end of the movable plate 23. A wedge block 33 is fixedly installed on the support plate 210. As the movable plate 23 moves upward driven by the pocket, the wedge block 33 on the support plate 210 also moves upward and is clamped between the hinge shaft 21 and the fuselage 1. When the fuselage flips over, the movable plate 23 is not affected by external force and no fall occurs. When the pocket is opened, the pocket 210 is moved back and forth, and the pressing plate ... 1 The gas inside increases, the pressure increases, the second airbag 31 expands and contacts the support plate 210, the support plate 210 is squeezed by the second airbag 31 and moves downward, thereby driving the wedge block 33 to move downward, so that the wedge block 33 is separated from the hinge shaft 21, so that the hinge shaft 21 is not restricted by the wedge block 33 and rotates clockwise, the movable plate 23 fixedly connected to the support plate 210 moves downward along the movable groove 22 under the action of the support plate 210, the card plate 3 fixedly connected to the movable plate 23 moves downward and squeezes the pocket to move downward, due to the force on the upper part of the pressing plate 2, the pressing plate 2 rotates clockwise with the hinge shaft 21 as the center, the opening between the pressing plate 2 and the fuselage 1 becomes larger, at this time the pressing plate 2 and the fuselage 1 are no longer in contact with the pocket, and the fuselage 1 is taken out of the pocket. ,

[0059] When the worker bends down, the fuselage 1 placed on the pocket flips over. At this time, the fuselage 1 slides down along the pocket under the action of gravity. A rubber spring 29 is installed at the lower end of the movable plate 23, and the surface of the rubber spring 29 is rough, which increases the contact area between the pressing plate 2 and the pocket, increases the friction between the pressing plate 2 and the pocket, and thus offsets part of the gravity. An elastic steel wire 35 is vertically installed on the side of the movable plate 23 facing the fuselage 1, and the rubber spring 29 covers the area where the elastic steel wire 35 is located. The surface of the rubber spring 29 is rough and evenly provided with through holes, and the through holes correspond to the elastic steel wire 35 one by one. When the bottom of the pressing plate 2 and the fuselage 1 clamp the pocket, the rubber spring 29 is squeezed, and the elastic steel wire 35 is inserted into the pocket fabric in contact with the rubber spring 29 through the through hole on the rubber spring 29, so that the pocket and the pressing plate 2 are not separated, so that when the fuselage 1 placed on the pocket is flipped over, the fuselage 1 is firmly clamped on the pocket and does not fall off.

[0060] In order to make the wedge block 33 and the hinge shaft 21 more tightly connected and prevent the fuselage 1 from falling when flipping, a spline is set at the center of the hinge shaft 21, and a locking groove is provided on the side of the wedge block 33 close to the hinge shaft 21. When the wedge block 33 contacts the hinge shaft 21, the spline engages with the locking groove, so that the wedge block 33 prevents the hinge shaft 21 from rotating clockwise without slipping.

[0061] Since the width of the cardboard 3 does not change with the change of the opening size, when the opening becomes larger and the pocket enters the gap between the fuselage 1 and the pressing plate 2, since the width of the cardboard 3 does not change, the end of the cardboard 3 close to the fuselage 1 is away from the fuselage 1, so that a gap is generated between the cardboard 3 and the fuselage 1. When the pocket is placed on the fuselage 1, the fabric at the top edge of the pocket directly passes through the gap between the cardboard 3 and the fuselage 1 and contacts the baffle plate without contacting the cardboard 3, so that the movable plate 23 cannot move upward under the action of the cardboard 3, and when the pressing plate 2 is not acted upon by force, the fabric at the top edge of the pocket exists between the cardboard 3 and the fuselage 1. When the force on the pressing plate 2 is removed, the fabric at the top edge of the pocket exists between the cardboard 3 and the fuselage 1. When the pressing plate 2 moves to its original position, the cloth at the top edge of the pocket exists between the card plate 3 and the fuselage 1, resulting in excessive extrusion force on the card plate 3, causing damage to the card plate 3. By installing an elastic sheet 34 at the end of the card plate 3 close to the fuselage 1, and the end of the elastic sheet 34 away from the card plate 3 is always close to the back of the fuselage 1, the cloth at the top edge of the pocket is blocked by the elastic sheet 34 after entering the gap between the pressing plate 2 and the fuselage 1, and does not enter the gap between the card plate 3 and the fuselage 1. The cloth at the top edge of the pocket contacts the concave part of the card plate 3, and the cloth at the top edge of the pocket drives the card plate 3 and the movable plate 23 to move upward along the movable groove 22.

[0062] When the fuselage 1 is put into the pocket, when the fuselage 1 is not perpendicular to the top edge of the pocket, the card plate 3 is not parallel to the top edge of the pocket, then the top edge of the pocket contacts one end of the card plate 3 and drives the movable plate 23 to move upward along the movable groove 22. When the force on the pressing plate 2 is removed, the fuselage 1 is clamped on the pocket at an angle. At this time, the fuselage 1 is unstable. When the pocket shakes, the fuselage 1 shakes left and right along the top edge of the pocket. The card plate 3 is arranged away from the second airbag 31 and is installed with evenly distributed elastic steel wires 35. When the pocket contacts the card plate 3, the elastic steel wires 35 on the card plate 3 are inserted into the fabric at the top edge of the pocket.

[0063] When the movable plate 23 is located at the bottom of the movable groove 22, the rectangular hole 231 is located below the movable groove 22, and the raised portion on the deformation piece 26 cannot extend from the rectangular hole 231. Therefore, the deformation piece 26 in the fixed groove 25 is squeezed by the movable plate 23, and the lower end of the deformation piece 26 slides downward in the fixed groove 25. When the movable plate 23 moves upward along the movable groove 22, the rectangular hole 231 moves upward, and the positions of the rectangular hole 231 and the movable groove 22 are offset. At this time, the rectangular hole 231 contacts the deformation piece 26, and the raised portion on the deformation piece 26 gradually extends out of the rectangular hole 231. Therefore, the raised portion on the deformation piece 26 moves along the rectangular hole 231 toward the fuselage 1. Since the upper end of the deformation piece 26 is fixed at the upper end of the fixed groove 25, the lower end of the deformation piece 26 slides freely in the fixed groove 25. Therefore, when the raised portion on the deformation piece 26 moves along the rectangular hole 231 toward the fuselage 1, the lower end of the deformation piece 26 moves upward. When the raised portion on the deformable sheet 26 moves toward the fuselage 1, the pocket enters the gap between the pressing plate 2 and the fuselage 1. As the raised portion on the deformable sheet 26 continues to move toward the fuselage 1, the raised portion on the deformable sheet 26 contacts the pocket and squeezes the pocket with the fuselage 1, thereby fixing the pocket. When the fuselage 1 is flipped over, the pocket and the pressing plate 2 have two force points, the deformable sheet 26 and the rubber spring sheet 29, so that the fuselage 1 does not fall when it is flipped over. When the movable plate 23 moves downward, the rectangular hole 231 on the movable plate 23 squeezes the raised portion on the deformable sheet 26, so that the lower end of the deformable sheet 26 moves downward, so that the distance between the upper end and the lower end of the deformable sheet 26 becomes farther, so that the raised portion on the deformable sheet 26 moves toward the pressing plate 2, and finally the raised portion on the deformable sheet 26 is retracted from the rectangular hole 231. The entire deformable sheet 26 is located on the side of the movable plate 23 facing the fixing groove 25, and the raised portion on the deformable sheet 26 does not contact the pocket. Then, the fuselage 1 is taken out of the pocket.

[0064] By providing a groove 11 on the back of the fuselage 1, the raised portion on the deformable sheet 26 and the fuselage 1 squeeze the pocket in the groove 11, thereby increasing the contact area between the pocket and the fuselage 1 and increasing the friction between the pocket and the fuselage 1.

[0065] A rubber layer 12 is installed in the groove 11. When the pocket is squeezed by the raised part on the deformation sheet 26 and the fuselage 1, the rubber layer 12 is acted upon by force, thereby causing the rubber layer 12 to deform. A short needle is installed in the rubber layer 12. After the rubber layer 12 is deformed, the short needle is exposed from the rubber layer 12, contacts the pocket and is inserted into the pocket, thereby fixing the pocket.

[0066] A No. 3 airbag 27 is installed on the upper end of the pressing plate 2 close to the fuselage 1. When the pressing plate 2 is acted upon by a force, the upper end of the pressing plate 2 close to the fuselage 1 contacts the fuselage 1, the No. 3 airbag 27 is squeezed, and the gas inside the No. 3 airbag 27 is compressed. The gas is discharged through the No. 2 pipe 28 connected to the No. 3 airbag 27. Since the opening end of the No. 2 pipe 28 is in the fixed groove 25 and the opening end of the No. 2 pipe 28 does not contact the deformation sheet 26, the gas from the No. 2 pipe 28 blows air to the surface of the deformation sheet 26, so that the thread ends, dust and other debris attached to the deformation sheet 26 after the contact with the pocket are removed.

[0067] When in use, the pressing plate 2 will be often pressed. After being pressed too much, the airbag No. 1 24 and the airbag No. 3 27 are prone to wear. The airbag No. 1 24 and the airbag No. 3 27 at the upper end of the pressing plate 2 are wrapped with a rubber skin 4, so that the airbag No. 1 24 and the airbag No. 3 27 will not directly contact the outside world, thereby protecting the airbag No. 1 24 and the airbag No. 3 27 from friction and wear. At the same time, by wrapping a layer of rubber skin 4 outside the airbag No. 1 24 and the airbag No. 3 27, the aesthetic effect of the pressing plate 2 is improved.
