Second, to reduce premature replacement of components housed within a cartridge for an image forming device, cartridge manufacturers have begun separating components having longer lifetimes from those having shorter lifetimes into separate replaceable units. Relatively long-life components such as the developing roller, the powder feed roller, and the powder discharge blade are placed in one replaceable unit (developing unit). The developer supply of the image forming apparatus, which is consumed relatively quickly compared to the components accommodated in the developing unit, is provided in the powder storage bin of the powder cartridge to be closely fitted to the developing unit, so that the powder cartridge can be independently replaced. In this configuration, the number of components housed in the compact is reduced as compared to conventional compacts.

An image forming apparatus having a separate cartridge and developing unit is susceptible to leakage of developer between a developer output port of the cartridge and a developer input port of the developing unit. When the toner cartridge is detached from the developing unit and removed from the image forming apparatus, leakage of the developer often occurs. When developer leakage occurs, operation, movement, or transportation of the image forming apparatus causes the developer to escape from the developer input port of the developing unit. The leaked developer may contaminate both the inner and outer surfaces of the image forming apparatus, not only being difficult to clean, but also causing reliability problems or print defects in some cases. Therefore, there is a need for a developer unit having a shutter for ensuring that developer does not escape from the developer unit when the cartridge is removed.

Providing such a shutter presents several challenges. First, the developer units must be accurately positioned relative to their corresponding photosensitive drums. Otherwise, a printing defect, such as "white gap" in the case where the developing roller is instantaneously separated from the photosensitive drum and developer is not supplied to the drum, may occur. Therefore, the force balance on the developing unit must be closely controlled. Second, the opening and closing of the shutter on the developer input port of the developer unit must correspond precisely to the insertion or removal of the toner cartridge and the opening and closing of the corresponding shutter on the developer output port of the toner cartridge. Third, both the shutter on the developer output port of the cartridge and the shutter on the developer input port of the developer unit must reliably open and close upon insertion and removal of the cartridge throughout the life of the components and throughout the part tolerances and the extent of the cartridge insertion path.

The present embodiment is directed to solving the technical problems in the prior art, and the details of the compact provided in the present embodiment are described below. The present embodiment may be based on the first embodiment, and further describes the urging device 150 in the first embodiment. Specifically, as shown in fig. 4 and 5, the developer outlet 1101 of the powder cartridge may be provided on the front portion 113, and toward the bottom portion 112. The main body portion 118 is a closed space for storing developer therein; the interior of the extension 119 is adapted to receive a chip component 160 (FIG. 5), and the chip component 160 may be mounted within the extension 119 through a bottom opening 1121 in the bottom 112.

Third embodiment, this embodiment is based on the second embodiment, and this embodiment describes the urging device 150 in detail, as shown in fig. 4 and 5, the urging device 150 may include a slider 151 and a pushing block 152, when the powder cartridge is mounted to the developing unit along the mounting direction (e.g., direction a in fig. 5), the slider 151 is first contacted with the developing unit to move the slider 151 relative to the housing 110, and then the pushing block 152 pushes the shutter of the developing unit to open the developer input port. Specifically, the sliding block 151 can move in a direction opposite to the installation direction a of the compact, and the movement of the sliding block 151 drives the pushing block 152 to extend out of the casing 110 in a direction perpendicular to the installation direction a (i.e., the pushing direction B of the pushing block 152).

In the embodiment, the slider 151 abuts against the developing unit, the slider 111 is stationary relative to the developing unit, and the powder cartridge moves relative to the developing unit in the mounting direction a, that is, the slider 151 moves relative to the housing 110 in the direction opposite to the mounting direction a, and the movement of the slider 151 drives the pushing block 152 to push the shutter of the developing unit in the direction B, so that the shutter on the developing unit can be opened quickly during the mounting of the powder cartridge on the developing unit, and when the powder cartridge is dismounted from the developing unit in the direction opposite to the mounting direction a, the slider 151 can be retracted relative to the housing 110 in the mounting direction a, the pushing block 152 is retracted, and the shutter of the developing unit is simultaneously retracted to be in the state of closing the developer input port.

During the process of moving the slider 151 relative to the housing 110, the elastic element 190 generates elastic deformation, for example, tensile deformation, and when the powder cartridge is removed from the developing unit, the contact between the slider 151 and the developing unit is cancelled, at this time, the elastic element 190 immediately restores the elastic deformation, and drives the slider 151 to slide along the installation direction a relative to the housing 110, so that the slider 151 drives the pushing block 152 to retract, and the shutter on the developing unit also retracts rapidly to a state of closing the developer input port. In the present embodiment, it is preferable that the elastic element 190 is an extension spring, and of course, the elastic element 190 in the present embodiment is not limited to be an extension spring, and those skilled in the art can select other elastic elements that can achieve the same function according to actual needs.

The elastic member 190 is detachably connected to the housing 110, so that the elastic member 190 can be easily disassembled and maintained. Preferably, the fixing frame in this embodiment can be installed at the bottom opening 1121 of the housing. The elastic member 190 in this embodiment serves to maintain the slider 151 at the first position not pushed by the developing unit, and when the slider 151 is at the first position, the elastic member 190 may be in a natural state, and when the slider 151 receives the pushing force from the developing unit, the elastic member 190 is further elongated as the slider 151 moves. In this embodiment, when the powder box is detached from the developing unit, the elastic element 190 recovers deformation to quickly restore the slider 151 to the initial position, the push block 152 retracts into the powder box, and the shutter on the developing unit can recover the closed state.

The installation operation process of the powder box provided by the embodiment is as follows: the second mounting portion 1523 of the push block 152 is mounted on the bottom of the second guide rail 154, then the slider 151 is mounted on the first guide rail 153 from the initial end of the first guide rail 153, at this time, the cylindrical protrusion of the first force application portion 1512 is mounted in the opening of the second force receiving portion 1521, then the fixing frame 1191 is mounted on the housing 110, and finally the elastic element 190 is connected with the connecting portion 1514 at one end and with the upper fixing portion 11911 of the fixing frame 1191 at the other end.

As shown in fig. 8A and 8B, the powder cartridge is in a position where it is not mounted to the developing unit, and at this time, the cylindrical protrusion of the first force application portion 1512 is mounted to the opening of the second force receiving portion 1521, and the push block 152 is located inside the housing 110.

In the process of mounting the powder box on the developing unit, the powder box is mounted on the developing unit along the mounting direction a, the components of the developing unit are in contact with the first force-receiving part 1511 of the slider 151, a force F1 is applied to the slider 151, so that the slider 151 moves along the direction opposite to the mounting direction a, during the movement of the slider 151, the first force-applying part 1512 moves along the track of the opening in the second force-receiving part 1521, the initial end 1521a and the end 1521B of the track of the opening have a height difference in the extending direction B, so that during the movement of the slider 151, the first force-applying part 1512 applies a force F2 to the second force-receiving part 1521, the direction of the force F2 is different along with the position where the cylinder contacts the opening, and the direction of the force F2 is perpendicular to the contact surface of the opening when the cylinder contacts; when the cylinder contacts the smooth curve 1521c of the opening, F2 has a component that moves the push block in the extending direction B, causing the push block 152 to extend in the extending direction B, and the push block 152 to extend from the housing 110. The pushing block 152 is extended to push the shutter of the developing unit, thereby opening the developer input port of the developing unit so that the developer in the cartridge can be fed to the developing unit. The slider 151 increases the amount of elastic deformation of the elastic member 190 during the movement, and F1 applied to the slider 151 by the developing unit overcomes the elastic force of the elastic member 190 to move the slider 151 in the direction opposite to the mounting direction a.

When the powder cartridge is removed from the developing unit, the force F1 applied to the first force receiving portion 1511 is removed, the slider 151 moves in the mounting direction a under the elastic force of the elastic element 190, the first force application portion 1512 applies a force to the second force receiving portion 1521 to retract the push block 152, and the force applied to the shutter of the developing unit by the second force application portion 1522 of the push block 152 is removed, so that the developer input port is closed. When the powder box is mounted or dismounted, the urging device 150 quickly opens or closes the developer input port, so that the risk of the developer escaping from the developer input port is reduced.

When the powder box is mounted on the developing unit, the power transmission member 155 ″ rotates in the forward direction, and the height of the contact part between the powder outlet opening and closing member 120 ″ and the second power conversion part 1557 ″ is gradually reduced, so that, during the rotation of the power transmission member 155 ″, the elastic potential energy of the elastic element 1204 ″, which is gradually extended, is gradually released, and the powder outlet opening and closing member 120 ″, which is taken along with the elastic element 1204 ″, is gradually moved in the direction B' opposite to the direction B until the elastic element 1204 ″, the developer outlet 1101 is opened by the powder outlet opening and closing member 120 ″. When the toner cartridge is removed from the developing unit, the power transmission member 155 ″ rotates in the reverse direction, and the height of the contact portion between the toner outlet opening/closing member 120 ″ and the second power conversion portion 1557 ″ gradually increases, so that, during the rotation of the power transmission member 155 ″, the elastic member 1204 ″ is gradually compressed, and the elastic member 1204 ″ gradually compresses and carries the toner outlet opening/closing member 210 ″ to move in the direction B until the developer outlet opening 1101 is closed by the toner outlet opening/closing member 120 ″.

Alternatively, as shown in fig. 16A, 16B and 35B, the second power conversion part 1557 "of the power transmission member 155" presses the power receiving part 1205 "in the direction B' opposite to the pushing direction B of the pushing block 152", and when the powder outlet opening/closing member 120 "is in the second position, the elastic member 1204" is in a natural state or a stretched state; when the power transmission member 155 'rotates in the forward direction, the second power conversion portion 1557' of the power transmission member 155 'further presses against the power receiving portion 1205' to further stretch the elastic element 1204 'until the powder outlet opening and closing member 120' moves to be in the first position. In this manner, the power receiving portion 1205 "is in contact with the other side of the second power conversion portion 1557", and the driving force applied to the power receiving portion 1205 "by the second power conversion portion 1557" is a pressing force in the direction B' opposite to the direction B. When the powder outlet opening/closing member 120 "needs to be in the second position for closing the developer outlet 1101 when the powder cartridge is not mounted on the developing unit, the power receiving portion 1205" of the powder outlet opening/closing member 120 "is pressed by the power transmitting member 155", and the elastic member 1204 "may be stretched or in the original length. When the toner cartridge is mounted on the developing unit, the power transmission member 155 ″ rotates in the forward direction, and the height of the contact portion between the toner outlet opening/closing member 120 ″ and the second power conversion portion 1557 ″ is gradually lowered, so that, during the rotation of the power transmission member 155 ″, the elastic member 1204 ″ is gradually stretched, and the elastic member 1204 ″ is gradually further extended and carries the toner outlet opening/closing member 120 ″ to be gradually moved in the direction B' opposite to the direction B until the developer outlet 1101 is opened by the toner outlet opening/closing member 120 ″. When the toner cartridge is removed from the developing unit, the power transmission member 155 "rotates in the reverse direction opposite to the direction C, and the height of the contact portion between the powder outlet opening/closing member 120" and the second power conversion portion 1557 "gradually increases, so that the stretched elastic member 1204" gradually recovers its shape during the rotation of the power transmission member 155 "and carries the powder outlet opening/closing member 120" to gradually move in the direction B until the developer outlet 1101 is closed by the powder outlet opening/closing member 120 ".

In addition, in this embodiment, further, the powder outlet switch 120 "may further have a guide rail along the moving direction of the pushing block 152", and the housing 110 has guide grooves on two sides of the developer outlet 1101, which are matched with the guide rail; alternatively, the powder outlet opening/closing member 120 "is provided with a guide groove 1207" along the moving direction of the pushing block 152 ", and the housing 110 is provided with guide rails on both sides of the developer outlet 1101 to be engaged with the guide groove 1207".

In order to facilitate the other end of the rotary member in the housing 2a to pass through the mounting hole provided in the mounting plate 11a corresponding to the rotary member before the mounting plate 11a is mounted to the housing 2a, the diameter of the mounting hole needs to be set larger than the diameter of the other end of the corresponding rotary member.

Because the diameter of the other end of the rotating member is smaller than the diameter of the corresponding mounting hole, when the rotating member rotates, the other end of the rotating member swings along the radial direction of the rotating member, so that the gears connected with the rotating member are displaced, the gears of the gear set are disengaged, the rotating force cannot be transmitted, and the rotating member in the housing 2a cannot stably rotate.

In order to make the transmission shaft 133, the stirring frame 134 and the screw 11041 capable of interlocking, that is, as one of the rotating members rotates, the other rotating member also rotates, a gear set 132 is further provided on the mounting plate 117. The gear set includes a first gear 1321, a second gear 1322, a third gear 1323, and a fourth gear 1324; the first gear 1321, the second gear 1322 and the third gear 1323 are respectively engaged with the transmission shaft 133, the stirring frame 134 and the other end of the screw 11041 which extends out of the mounting hole of the mounting plate 117; the fourth gear 1324 is an intermediate transmission gear.

When the other end of the transmission shaft 133 protruding from the first mounting hole 1171 of the mounting plate 117 is inserted into the through hole 13211a of the first gear 1321, the first gear 1321 rotates along with the rotation of the transmission shaft 133, and the rotation axis of the first gear 1321 coincides with the rotation axis of the transmission shaft 133.

In addition, the diameter of cylindrical protrusion 1321a is slightly smaller than the inner diameter of annular first locating protrusion 1174. Specifically, the fit tolerance between the diameter of the cylindrical boss 1321a and the inner diameter of the first positioning boss 1174 is 0.05mm to 0.2mm, and preferably 0.05mm to 0.1 mm. When the first gear 1321 is mounted to the mounting plate 117, the cylindrical boss 1321a of the first gear 1321 is inserted into the first positioning boss 1174, the third positioning surface 13211b of the cylindrical boss 1321a is brought into contact with the first positioning surface 1174a of the circular-arc shape of the first positioning boss 1174, and the first gear 1321 is rotatable relative to the first positioning boss 1174.

The first gear 1321 is positioned by the engagement of the first locating surface 1174a and the third locating surface 13211b so that the first gear 1321 is not displaced during rotation.

In addition, as shown in fig. 41, a second cylindrical recess 1178 coaxial with the rotation axis is provided around the through hole 13211a at one end of the first gear 1321 in the rotation axis direction of the first gear 1321. When the other end of the transmission shaft 133 is inserted into the through hole 13211a of the first gear 1321, the rotation axis of the first gear 1321 coincides with the rotation axis of the transmission shaft 133. The circular-arc inner surface of the second cylindrical recess 1178 in the direction away from the rotational axis of the first gear 1321 is a fourth positioning surface 1178 a. The outer diameter of the first positioning protrusion 1174 is slightly smaller than the inner diameter of the second cylindrical recess 1178, specifically, the matching tolerance between the inner diameter of the second cylindrical recess 1178 and the outer diameter of the first positioning protrusion 1174 is 0.05mm to 0.2mm, preferably 0.05mm to 0.1mm, when the first gear 1321 is mounted on the mounting plate 117, the first positioning protrusion 1174 is inserted into the second cylindrical recess 1178 of the first gear 1321, and the fourth positioning surface 1178a of the second cylindrical recess 1178 is in contact with the second positioning surface 1174b of the first positioning protrusion 1174, so that the first gear 1321 can rotate relative to the first positioning protrusion 1174.

To protect the gears and prevent the gears from moving in the direction of the axis of the rotating member, a baffle 180 (shown in FIG. 37) is mounted to the mounting plate 117 and covers the gear set 132 after the gear is installed. The baffle 180 may be fastened to the mounting plate 117 by snapping, gluing, welding, or screws.

Twenty-two embodiments, the present embodiment provides a structure of a baffle plate, which prevents a rotating member from swinging during rotation. As shown in fig. 43 and 44, a blocking plate 180 is mounted on the mounting plate 117 for protecting the gear set 132 and preventing the gears of the gear set 132 from moving in the rotational axis direction. In the present embodiment, the baffle plate 180 is provided with a first positioning hole 181, a second positioning hole 182, and a third positioning hole 183 on one side in the thickness direction. The positioning hole may be a circular hole formed by protruding from the baffle plate 180, or a circular hole formed by forming a groove in the baffle plate 180, and in particular, may be determined according to the thickness of the baffle plate 180 and the space between the baffle plate 180 and the gear set 132. The first positioning hole 181, the second positioning hole 182, and the third positioning hole 183 of the baffle plate 180 overlap with the drive shaft 133, the agitator frame 134, and the screw 11041 in the housing 110, respectively, in the direction of the rotational axis of the drive shaft 133. And the diameters of the first positioning hole 181, the second positioning hole 182, and the third positioning hole 183 are substantially the same as the maximum rotation diameters of the transmission shaft 133, the agitator 134, and the other end of the screw 11041, respectively.

By setting the lengths of the transmission shaft 133, the stirring frame 134 and the screw 11041, after the transmission shaft 133, the stirring frame 134, the screw 11041, the mounting plate 117, the first sealing element 71a, the second sealing element 72a, the third sealing element 73a and the gear set 132 are mounted, the other ends of the transmission shaft 133, the stirring frame 134 and the screw 11041 penetrate through the through hole of the gear and then continuously extend outwards for a certain distance. Then, the baffle plate 180 is mounted on the mounting plate 117, and the parts of the transmission shaft 133, the stirring frame 134 and the screw 11041, which extend out of the gear set 132, are respectively inserted into the first positioning hole 181, the second positioning hole 182 and the third positioning hole 183, so that the other ends of the transmission shaft 133, the stirring frame 134 and the screw 11041 are positioned.

The positioning function of the positioning hole on the rotating member will be described below by taking the first positioning hole 181 and the transmission shaft 133 as an example. As shown in fig. 45A, the non-circular cross-section of the other end of the driving shaft 133 has a "D" shape, the maximum diameter of revolution of which is substantially the same as the inner diameter of the first positioning hole 181, and when the driving shaft 133 rotates, the circular arc inner surface 1811 of the first positioning hole 181 is always in contact with the circular arc outer surface of the other end of the driving shaft 133, thereby restricting the movement of the other end of the driving shaft 133 in the radial direction and preventing the first gear from being displaced. Alternatively, as shown in fig. 45B, the non-circular cross section of the other end of the transmission shaft 133 is in a regular hexagon structure inscribed in the circular arc inner surface 1811 of the first positioning hole 181, and when the transmission shaft 133 rotates, the six ridges of the other end of the transmission shaft 133 are always in contact with the circular arc inner surface 1811 of the first positioning hole 181, so that the other end of the transmission shaft 133 is prevented from moving in the radial direction during the rotation of the transmission shaft 133, and the first gear is prevented from being displaced. The matching relationship between the stirring frame 134 and the other end of the screw 11041 and the second positioning hole 182 and the third positioning hole 183 can refer to the matching relationship between the other end of the transmission shaft 133 and the first positioning hole 181, and will not be described herein again.

Of course, a person skilled in the art may also arrange the rotating member and the gear as a whole instead of arranging the mounting hole on the gear, for example, arrange the mixing rack and the second gear as a whole, when installing the mixing rack, one end of the mixing rack passes through the mounting hole of the mounting plate, then install the mixing blade on the mixing rack, and the positioned portion of the gear is connected with the positioned portion of the mounting plate, so as to position the gear on the mounting plate.

Through the scheme of the twenty-first embodiment and the twenty-second embodiment, the situation that gears cannot be meshed with each other and a rotating part cannot stably rotate due to the fact that the other ends of the transmission shaft 133, the stirring frame 134 and the screw 135 are displaced along the radial direction in the rotating process of the transmission shaft 133, the stirring frame 134 and the screw 11041 can be effectively prevented, the mounting steps of the bearing plate are reduced, only the positioning part needs to be arranged on the mounting plate or the baffle plate, the positioned part is arranged on the gear, materials are saved, and efficiency is improved.

The process of taking out the compact from the image forming apparatus by the handle portion 140 will be described in detail below. After the powder cartridge is installed in the image forming apparatus in the Y direction, as shown in fig. 49A, during the closing process of the door cover (not shown) of the image forming apparatus, the door cover contacts the elastic portion 140b of the handle portion 140, and applies a force F in the Y direction to the elastic portion 140b, so that the elastic portion 140b rotates along with the handle portion 140 around the connecting shaft 1401 in the direction opposite to the M direction until the handle portion 140 rotates to a position where the substrate 140a contacts the top surface 110b of the casing 110 in the Y direction or is parallel to the top surface, and the door cover continues to be closed, and the elastic portion 140b swings in the Y direction relative to the substrate 140a under the pressure of the door cover and is finally pressed into the groove 140c on the substrate 140a by the door cover.

When the compact is taken out of the image forming apparatus, as shown in fig. 49B, as the door cover is opened, the force applied by the door cover to the elastic plate 140B is gradually smaller and finally disappears, and the elastic plate 140B returns to the original position, so that the user can easily grasp the elastic plate 140B and apply a force in the direction opposite to the direction Y to the elastic plate 140B, so that the elastic plate 140B drives the handle portion 140 to rotate around the connecting shaft 1401 in the direction M relative to the housing 110 until the positioning portion 110a of the housing 110 contacts the positioned portion 140d1 of the connecting plate 140d (as shown in fig. 47). At this time, a gap 1402 (as shown in fig. 47) is formed between the base plate 140a of the handle 140 and the top surface 110b of the casing 110, and the user can easily grasp the base plate 140a through the gap 1402 and apply a force in the Y direction to the base plate 140a, thereby taking out the compact in the Y direction from the image forming apparatus.

Of course, as shown in fig. 50, it is easily contemplated by those skilled in the art that the elastic plate 140b of the handle part 140 is disposed on the other side of the substrate 140a, i.e., the elastic plate 140b is located between the substrate 140a and the top surface 110b of the housing 110, and the door cover applies a force to the substrate 140a and then presses the elastic plate 140b through the substrate 140a, which also satisfies the above requirements.

Further, since the door cover of the image forming apparatus is closed, the door cover applies a force to the elastic plate 140b to bend the elastic plate 140b in the Y direction, that is, the elastic plate 140b applies an opposite elastic force to the door cover. When the door cover is opened, the door cover is more easily opened by the elastic force applied to the door cover by the elastic plate 140 b. Through the technical scheme of this embodiment, simplified handle portion's simple structure, the dependable performance.

Twenty-four in the embodiment, as shown in fig. 51 and 52, the present embodiment is further improved on the basis of twenty-three in the embodiment, specifically, an elastic grabbing portion 1402b is further connected to the elastic plate 140b, and the elastic grabbing portion 1402b is bent toward the base plate 140 a. The type of the elastic grabbing portion 1402b may be the same as the type of the elastic plate 140b, for example, all of which may be made of spring steel sheet, but the embodiment is not limited thereto, and those skilled in the art may also use other materials meeting the requirements according to actual situations. The elastic grabbing portion 1402b may be integrally formed with the elastic plate 140b, or may be separately formed and then connected together by a connecting member, or connected together by other methods such as bonding, welding, etc., and the embodiment is not limited thereto.

The present embodiment may further facilitate the operator to grasp the handle by providing the elastic grasping portion 1402b on the elastic plate 140b, and since the elastic grasping portion 1402b is bent toward the base plate 140a, the elastic grasping portion 1402b may further improve the elastic force of the handle in combination with the elastic plate 140b, so that the door cover is more easily opened.

Specifically, the elastic grip portion 1402b may include a connecting portion 14021b and two resilient portions 14022b disposed at both ends of the connecting portion 14021b, the connecting portion 14021b being connected to the elastic plate 140b, the resilient portions 14022b being bent toward the base plate 140 a. Preferably, the connection portion 14021b may extend in a direction parallel to the base plate 140a in a state where the elastic plate 140b is sprung. The two springback portions 14022b may be symmetrically disposed on two sides of the connecting portion 14021b, and the two sides of the connecting portion 14021b may have the same bending degree, so that the elastic plate 140b and the elastic grabbing portion 1402b can provide a stable elastic force to the door when springing back, and the stress on the door is balanced. Of course, it is understood that the number of the resilient portions 14022b is not limited to two, and may be three or more, and when there are a plurality of resilient portions 14022b, the resilient portions 14022b may be uniformly arranged.

Further, the connecting portion 14021b and the resilient portion 14022b are connected by an arc transition. The connecting portion 14021b and the springback portion 14022b are in arc transition, so that stress concentration at the connecting portion can be reduced as much as possible, and the whole elastic grabbing portion 1402b is not easy to deform.

The ends of the resilient portions 14022b can be parallel to the substrate 140 a. This ensures that the end of the resilient portion 14022b can also be attached to the base plate 140a or the top surface 110b when the door is closed.

In the compact provided in the present embodiment, when the door cover applies the force F in the direction a to the elastic grip portion 1402b, the two resilient portions 14022b press against the substrate 140a or the top surface 110b, so that the elastic grip portion 1402b expands and deforms toward the two sides of the compact until the elastic grip portion 1402b is attached to the substrate 140a or the top surface 110 b. Specifically, the pressing position of the elastic grabbing portion 1402b is related to the size of the elastic grabbing portion 1402b, and is used for being attached to and contacted with the top surface 110b if the elastic grabbing portion 1402b extends out of the substrate 140a, and is used for being attached to and contacted with the substrate 140a if the elastic grabbing portion 1402b does not extend out of the substrate 140a, which is not limited in this embodiment.

Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
