Description

Technical Field

[0001] This utility model belongs to the field of stamping machine technology, and in particular to a self-inking stamping machine with a soft connection structure. Background Technology

[0002] A seal is a stationery item used to mark documents for authentication or signature. Generally, seals are first dipped in ink before being applied. There are also seals that are applied directly to a flat surface without ink, creating an embossed mark; these are called steel seals. Other types are wax seals, such as those on wax or sealing wax, or wax stamps on envelopes. Throughout history, seals have been made from materials including jade, metal, wood, and stone.

[0003] With the development of the seal industry, manual stamping has gradually been replaced by automated mechanical stamping. Stamping machines can replace manual stamping and are widely used as office equipment.

[0004] Chinese patent document CN113478991A discloses an ink return mechanism and a stamp device. The ink return mechanism includes a bracket and a sleeve slidably fitted on the bracket. A stamp clamp for holding the stamp is provided inside the bracket, and the stamp clamp is fixedly connected to the sleeve. One end of the bracket forms a stamping area. The orthographic projection of the stamp surface held by the stamp clamp is located within the stamping area. A cover for abutting and covering the stamp surface is also provided inside the bracket. The cover is rotatably connected to the bracket and the sleeve via a support shaft. Pushing the sleeve to slide towards the stamping area causes the cover to rotate with the support shaft, exposing the stamp surface. The stamp moves linearly to the stamping area of ​​the bracket for stamping operation.

[0005] Under the above technical solution, the security of the seal cannot be guaranteed when the user performs unauthorized operations, and instant disconnection cannot be achieved; therefore, it is necessary to develop a new self-inking stamping machine that can prevent unauthorized operations while performing normal locking, stamping, and stamping actions. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a self-inking stamping machine with a soft connection structure, which can prevent unauthorized operation of the stamp while performing normal locking, stamping and collecting actions.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: the self-inking stamping machine with a flexible connection structure includes a stamp locking mechanism, a stamp sleeve, and an ink cartridge mechanism. The stamping machine also includes an outer sleeve, in which a stamp movement channel is provided. The stamp in the stamp sleeve can reciprocate within the stamp movement channel. The stamp locking mechanism, the stamp sleeve, and the ink cartridge mechanism are all located within the outer sleeve, and the stamp locking mechanism is connected to the outer sleeve through a flexible connection structure.

[0008] The stamp movement channel inside the outer casing allows the stamp to move in a fixed direction along the channel, structurally minimizing the size of the self-inking stamping machine and eliminating the need for additional space for stamp flipping. The flexible connection structure prevents the connection between the locking mechanism and the outer casing from being rigid or dead. Instead, upon receiving an instruction, the connection between the locking mechanism and the outer casing can be instantly disconnected (the stamp will retract into the outer casing and return to its initial state), preventing unauthorized use of the stamp and ensuring stamp security.

[0009] Preferably, the flexible connection structure includes a movable cover that can slide up and down on the outside of the outer sleeve, the movable cover being used to drive the locking mechanism to move vertically in the stamp movement channel; the stamp sleeve and the locking mechanism are connected together.

[0010] The movable cover is located on the outside of the outer cover, making it easier for users to operate and providing a better user experience; the stamp sleeve and the locking mechanism are connected together, and structurally, this ensures that the movable cover drives the locking mechanism while also causing the stamp in the stamp sleeve to move vertically in the stamp movement channel.

[0011] Preferably, the flexible connection structure further includes a movable groove disposed vertically on the outer casing, and the movable cover moves vertically along the movable groove; the movable groove guides the vertical movement of the movable cover.

[0012] Preferably, a lock head slide groove is provided on the movable groove; a movable block is provided on the movable cover, and a lock head groove is provided on the movable block; a soft connection lock head is provided on the locking mechanism, and a soft connection lock head groove is provided on the movable groove.

[0013] The soft-connection lock head and the soft-connection lock head groove work together to achieve a soft connection between the seal locking mechanism and the movable cover. This soft connection will be instantly disconnected when the user performs an unauthorized operation (the seal will retract into the mechanism and return to its initial state), ensuring the security of the seal. The lock head groove, lock head slide groove and lock head work together to realize the seal locking function.

[0014] Preferably, the locking mechanism includes a motor, which drives the locking head in the locking mechanism to extend and retract; the locking mechanism also includes a return structure, which is used to return the stamp in the stamp sleeve to its initial state after stamping.

[0015] The extension and retraction of the locking head allows the self-inking stamping machine to be in the locking, stamping, and retracting states; the return structure ensures that the retracting action is completed, and that the stamp is in a protected state when the movable cover is not moving downwards.

[0016] Preferably, the recovery structure includes a spring; one end of the spring is connected to the locking mechanism, and the other end is connected to the outer casing.

[0017] Preferably, a pressure sensor is provided on the locking mechanism, the pressure sensor being used to detect the pressure exerted on the seal in the seal sleeve.

[0018] When a stamp is applied, the user applies a certain amount of pressure, which is detected by a pressure sensor. If the pressure sensor does not detect pressure, it means that the stamp has been removed from the stamping device. In this case, the stamping machine's control terminal (control board) must retract the stamp based on the transmitted pressure change signal; otherwise, there is a risk of stamp theft.

[0019] Preferably, a magnet is provided on the locking mechanism, and a Hall effect detection switch is provided on the top of the outer casing; the Hall effect detection switch is used to detect the magnetic flux of the magnet and feed the detected information back to the control board.

[0020] The magnetic flux of the magnet is detected by a Hall effect switch, and the lock mechanism is determined to be in a zero-state by measuring the change in the strength of the magnetism.

[0021] Preferably, the seal locking mechanism is provided with a seal sleeve lock buckle, which is connected to the seal sleeve in a locking assembly; the seal sleeve lock buckle can be unlocked by the motor, so that the seal sleeve is disengaged from the seal locking mechanism.

[0022] When a stamp needs to be changed, the motor drives the unlocking mechanism, allowing the stamp sleeve to detach from the outer casing of the ink return stamping machine.

[0023] Preferably, the motor can drive the locking head to extend and retract, so that the stamping machine can sequentially perform the actions of locking, stamping and collecting the stamp.

[0024] Preferably, the locking mechanism is further provided with a turntable, on which an arc-shaped groove is arranged, and a drive rod connected to the lock head is located in the arc-shaped groove; the motor drives the turntable to rotate, and the turntable drives the drive rod to drive the lock head to perform a telescopic movement.

[0025] Preferably, the lock head protrudes further outward than the flexible connection lock head, and both the lock head and the flexible connection lock head are disposed on the bolt of the locking mechanism; the bolt is disposed below the turntable, wherein the flexible connection lock head cooperates with the flexible connection lock head groove, and the lock head passes through the lock head slide groove and cooperates with the lock head groove; the flexible connection lock head groove and the lock head slide groove are disposed on the outer sleeve, and the lock head groove is disposed on the movable cover.

[0026] Preferably, the control board is located inside the head of the outer casing; the head of the casing is equipped with a camera and an infrared receiver.

[0027] The camera identifies the stamping area to prevent unauthorized use of the stamp; the infrared receiver receives signal commands; and the control board receives external commands and issues control commands to the various internal components of the self-inking stamping machine.

Detailed Implementation

[0055] As attached Figures 1-4As shown, the self-inking stamping machine 1 with a flexible connection structure in this embodiment includes a locking mechanism 2, a stamp sleeve 3, and an ink cartridge mechanism 4, as well as an outer sleeve 5. An ink cartridge 6 is provided inside the outer sleeve 5, and the stamp 302 in the stamp sleeve 3 can reciprocate within the ink cartridge 6. The locking mechanism 2, the stamp sleeve 3, and the ink cartridge mechanism 4 are all located inside the outer sleeve 5 and are arranged sequentially along the extension direction of the ink cartridge 6. The ink cartridge mechanism 4 is disposed on the transverse section of the ink cartridge 6. Figure 2 As shown; the locking mechanism 2 and the outer casing 5 are connected by a flexible connection structure.

[0056] like Figures 7.0-7.3 As shown, one side 406 of the ink cartridge mechanism 4 is flipped and connected to the outer sleeve 5 (in this embodiment, this is achieved through a flipping shaft 408). That is, a flipping connection structure is provided on one side of the ink cartridge mechanism 4, allowing the ink cartridge mechanism 4 to be flipped to the side of the stamp movement channel 6. The ink cartridge mechanism 4 has at least one other side 407 with a detachable connection structure, which is detachably connected to the outer sleeve 5 (in this embodiment, the detachable connection is achieved through a magnetic attraction connection between magnets). When the stamp 302 in the stamp sleeve 3 moves downward along the stamp movement channel 6 to stamp, it takes ink. After taking ink, the stamp 302 continues to move downward, which can disconnect the detachable connection between the side 407 of the ink cartridge mechanism 4 and the outer sleeve 5, pushing the ink cartridge mechanism 4 to flip to the side of the stamp movement channel 6, making room for the stamp 302 to stamp and move downward.

[0057] The ink cartridge mechanism 4 includes an ink cartridge 401 and a baffle 402, such as Figure 7.0 As shown, the ink cartridge 401 is detachably fitted together with the baffle 402; a flip shaft 408 is provided on the baffle 402, and the ink cartridge mechanism 4 is flipped to the side of the stamp movement channel 6 via the flip shaft 408; the flip shaft 408 is part of the flip connection structure.

[0058] baffle 402 has a base plate 40201, such as Figure 7.1 As shown, a first side plate 40202 and a second side plate 40203 extend upward from both sides of the base plate 40201; a first sliding groove 40204 (located opposite to the second sliding groove 40205) is respectively provided on the first side plate 40202 and the second side plate 40203. Figure 7.1 (Only showing the position) and the second groove 40205, correspondingly, a first protrusion 40101 and a second protrusion 40102 (located on the opposite side of the first protrusion 40101) are respectively provided on both sides of the ink cartridge 401, such as Figure 7.3 As shown.

[0059] It should be noted that the height of the first side plate 40202 and the second side plate 40203 is the same as the height of the ink box 401.

[0060] exist Figure 7.1 Furthermore, it can be seen that the ink cartridge mechanism 4 also includes a self-locking structure 403, which has a latch 40301 and a locking groove 40302. The latch 40301 is disposed on the ink cartridge 401, and the locking groove 40302 is disposed on the baffle 402. The latch 40301 and the locking groove 40302 are fitted together to complete the self-locking.

[0061] The lock groove 40302 includes an upper lock groove piece 40303 and a lower lock groove piece 40304. The lock opening 40305 formed by the upper lock groove piece 40303 and the lower lock groove piece 40304 is narrower than the locking slide plate 40306 of the lock groove 40302.

[0062] A slide elastic member 404 is provided at the end of the first slide groove 40204 or the second slide groove 40205; the slide elastic member 404 is used to be compressed inward by the ink cartridge 401 when the self-locking structure 403 is locked, and to pop the ink cartridge 401 outward when the self-locking structure 403 is unlocked.

[0063] When the baffle 402 needs to be fitted with the ink cartridge 401, the first protrusion 40101 is embedded in the first slide groove 40204, and the second protrusion 40102 is embedded in the second slide groove 40205. Continuous pushing compresses the slide groove elastic element 404. The latch 40301 enters the locking groove 40302 through the locking opening 40305 and is positioned on the latch sliding plate 40306. Removing the pushing force causes the slide groove elastic element 404 to provide elastic restoring force to the ink cartridge 401, pushing the ink cartridge 401 outwards. Since the locking opening 40305 is narrower than the latch sliding plate 40306 of the locking groove 40302, the latch 40102... When 301 is pressed down by the lower locking groove 40304 and embedded in the locking groove 40302, the baffle 402 and the ink cartridge 401 can be assembled. During disassembly and assembly, the compression of the sliding groove elastic element 404 causes the latch 40301 to move downwards from the upper locking groove 40303. The sliding groove elastic element 404 will generate a pushing force that pushes the ink cartridge 401 outwards. At this time, with a little force, the latch 40301 can be lifted out along the upper locking groove 40303 towards the locking opening 40305. The latch 40301 embedded in the locking groove 40302 can then be disassembled from the locking groove 40302, thus realizing the disassembly of the baffle 402 and the ink cartridge 401.

[0064] A hook 405 is provided at the end of the baffle 402, and a support rod 301 is provided on the sleeve 3 (e.g., Figure 9.0 (as shown); the flipping shaft 408 is located below the hook 405, and the flipping shaft 408 is mounted on the outer sleeve 5.

[0065] like Figure 2 As shown, the flip shaft 408 is fitted onto the outer casing 5; from Figure 3 , Figure 4 It can be clearly seen that when the stamp sleeve 3 returns to its initial position, the support rod 301 on the stamp sleeve 3 supports the hook 405 of the baffle 402 upwards. The specific working principle is as follows: when the stamp 302 moves downwards along the stamp movement channel 6 in the stamp sleeve 3, the stamp 302 completes ink intake in the ink cartridge 401 and simultaneously applies a pushing force to the ink cartridge mechanism 4, completely breaking the disconnectable connection between it and the outer sleeve 5. This causes the ink cartridge mechanism 4 to flip downwards based on the flipping shaft 408 (at this time, the support rod 301 disengages from the hook 405), and the ink cartridge mechanism 4 flips 90 degrees to the rightmost side of the stamp movement channel 6, clearing the path for the stamp 302 to move downwards. The stamping process ends when the stamp 302 moves upward along the stamp movement channel 6 in the stamp sleeve 3. The restoring force of the return structure 203 on the locking mechanism 2 pulls the stamp sleeve 3 back to its initial position. The ink cartridge mechanism 4 rotates upward based on the flipping shaft 408. At this time, the support rod 301 contacts the support hook 405 and pulls the ink cartridge mechanism 4 to rotate upward. The rotation of 90 degrees makes the ink cartridge mechanism 4 return to the transverse section position of the stamp movement channel 6, preventing the stamp 302 from being exposed. The ink return process is completed.

[0066] The ink cartridge 401 is provided with a connecting block 40103, and the outer casing 5 is provided with a connecting block 40104 that cooperates with the connecting block 40103. The connecting block 40103 and the connecting block 40104 form a detachable connection structure. The ink cartridge mechanism 4 is detachably connected to the outer casing 5 through the connecting block 40103 and the connecting block 40104. Both the connecting block 40103 and the connecting block 40104 are magnets. Figure 7.0 In the middle, the connecting block 2 40104 on the right side is fitted onto the outer sleeve 5. The ink cartridge mechanism 4 and the outer sleeve 5 are connected together by the magnetic attraction between the connecting block 1 40103 and the connecting block 2 40104. When the external force (the pushing force of the stamp 302 in the stamp sleeve 3 moving downward along the stamp movement channel 6) exceeds the magnetic attraction, the two can be separated.

[0067] like Figure 7.2 , Figure 7.3 As shown, the base plate 40201 has an oil filling hole 40206, and the bottom of the ink cartridge 401 is provided with an ink inlet 40105; after the ink cartridge 401 and the baffle 402 are assembled, the oil filling hole 40206 and the ink inlet 40105 are stacked together. Figure 7.2In the image, we can also see that the ink cartridge 401 has multiple interconnected oil channels 40106 at the location where the sponge is placed. These oil channels 40106 are all connected to the ink inlet 40105, which makes it easy for the stamp to pick up ink.

[0068] like Figure 2 As shown, the flexible connection structure includes a movable cover 501 that can slide up and down on the outside of the outer sleeve 5. The outer sleeve 5 includes a stamp tube 502 and a movable cover 501. The movable cover 501 is used to drive the stamp locking mechanism 2 to move vertically in the stamp movement channel 6. The stamp sleeve 3 and the stamp locking mechanism 2 are connected together. The flexible connection structure also includes a movable groove 503 arranged vertically on the outer sleeve 5. The movable cover 501 moves vertically along the movable groove 503.

[0069] like Figure 10.0 As shown, a lock head slide groove 504 is provided on the movable groove 503; a movable block 505 is provided on the movable cover 501, and a lock head groove 506 is provided on the movable block 505, as shown. Figures 10.1-10.4 As shown; the locking mechanism 2 is equipped with a soft-connection lock head 2010, as... Figures 8.3-8.5 As shown, the movable slot 503 is provided with a soft connection lock slot 507.

[0070] like Figure 8.0 , Figures 8.1-8.6 As shown, the locking mechanism 2 includes a motor 201, which drives the locking head 202 in the locking mechanism 2 to extend and retract; the locking mechanism 2 also includes a return structure 203, which is used to return the stamp 302 in the stamp sleeve 3 to its initial state after stamping.

[0071] like Figure 8.3 As shown, the return structure 203 includes a spring 20301, one end of which is connected to the locking mechanism 2, and the other end is connected to the outer casing 5, as shown. Figure 2 As shown, the outer sleeve is fixedly connected to the head 9. In this embodiment, the other end of the spring 20301 is actually connected to the outer sleeve 5 by being fixed to the head 9.

[0072] A pressure sensor 7 is provided on the locking mechanism 2, such as Figure 8.4 As shown, the pressure sensor 7 is used to detect the pressure on the stamp 302 in the stamp sleeve 3.

[0073] The locking mechanism 2 is equipped with a magnet 204, such as Figure 8.1As shown, a Hall effect switch 205 is installed on the top of the outer casing 5 (at the head 9 position); the Hall effect switch 205 is used to detect the magnetic flux of the magnet 204 and feeds back the detected information to the control board 8, such as... Figure 8.2 As shown.

[0074] The locking mechanism 2 is equipped with a seal sleeve lock 206, such as Figure 8.3 , Figure 8.4 As shown, the seal sleeve latch 206 is locked and connected to the seal sleeve 3; the seal sleeve latch 206 can be unlocked by the motor 201, causing the seal sleeve 3 to disengage from the locking mechanism 2, as shown. Figure 9.1 , Figure 9.2 As shown.

[0075] The motor 201 can drive the lock head 202 to extend or retract, such as Figure 8.5 , Figure 8.6 As shown, the ink return stamping machine 1 with a soft connection structure can sequentially perform the actions of locking, stamping, and collecting the stamp.

[0076] The locking mechanism 1 is also provided with a turntable 207, on which an arc-shaped groove 208 is arranged, and a drive rod 209 connected to the lock head 202 is located in the arc-shaped groove 208; the motor 201 drives the turntable 207 to rotate, and the turntable 207 drives the drive rod 209 to drive the lock head 202 to perform extension and retraction.

[0077] It is important to note that, from Figures 8.3-8.5 It is clearly visible that the lock cylinder 202 (two are shown in the figure) protrudes further outward than the soft-connection lock cylinder 2010. Both lock cylinder 202 and soft-connection lock cylinder 2010 are mounted on the bolt 2011, which has two bolts, as shown in the figure. Figure 8.6 As shown; the two locking tongues are located below the turntable 207, as... Figure 8.5 As shown; wherein, the flexible connection lock head 2010 cooperates with the flexible connection lock head groove 507, while the lock head 202 passes through the lock head slide groove 504 and cooperates with the lock head groove 506; the flexible connection lock head groove 507 and the lock head slide groove 504 are provided on the stamp tube 502 of the outer sleeve 5 (in this embodiment, the movable groove 503 is also provided on the stamp tube 502), and the lock head groove 506 is provided on the movable cover 501.

[0078] The specific working principle is as follows:

[0079] In the initial state, the motor 201 on the locking mechanism 2 of the self-inking stamping machine with a flexible connection structure has driven the turntable 207 to rotate, and the turntable 207 has rotated counterclockwise to the end. Figure 8.5As shown, at this time, the drive rod 209 drives the latch 2011 to extend to the maximum, that is, the drive rod 209 is furthest from the center of the turntable 207. The lock head 202 on the latch 2011 passes through the lock head slide 504 and engages with the lock head groove 506. The flexible connection lock head 2010 on the latch 2011 engages with the flexible connection lock head groove 507. At this time, the movable cover 501 cannot move up and down to drive the stamp sleeve 3 (the stamp sleeve 3 and the stamp locking mechanism 2 are assembled together) to stamp. The flexible connection lock head 2010 engages with the flexible connection lock head groove 507 to lock the stamp locking mechanism 2 in the initial position (stamp locking).

[0080] Upon receiving the stamping instruction, the motor 201 on the locking mechanism 2 drives the turntable 207 to rotate clockwise until the soft connection lock head 2010 and the soft connection lock head groove 507 are disengaged and no longer in contact. At this time, the lock head 202 on the lock tongue 2011 is still in the state of passing through the lock head slide groove 504 and engaging with the lock head groove 506. Pulling down the movable cover 501 can drive the stamp sleeve 3 (the stamp sleeve 3 and the locking mechanism 2 are assembled together) to stamp.

[0081] It should be noted that after stamping an authorized document, if the self-inking stamping machine with a flexible connection structure receives a signal that the user will begin stamping an unauthorized document, it will issue a stamp retraction command. The motor 201 on the locking mechanism 2 will drive the turntable 207 to continue rotating clockwise until the locking head 202 on the locking tongue 2011 disengages from the locking head groove 506. The return mechanism on the locking mechanism 2 will then pull the locking mechanism 2 (along with the stamp sleeve 2) back to its initial position, meaning the stamp 302 has been moved upwards. Once the seal has moved to its initial position (seal closed), the motor 201 on the seal locking mechanism 2 drives the turntable 207 to rotate counterclockwise until the soft connection lock head 2010 on the latch 2011 engages with the soft connection lock head groove 507. However, the lock head 202 on the latch 2011 has not reached the state of engaging with the lock head groove 506 through the lock head slide 504. Even though the movable cover 501 can move freely up and down, it cannot perform unauthorized stamping actions. This is the so-called soft connection method between the seal locking mechanism 2 and the outer cover 5, which is achieved through a soft connection structure.

[0082] Once a normal stamping action is completed, the user can release the force that drives the movable cover 501 downwards. The return structure on the locking mechanism 2 will then pull the locking mechanism 2 (along with the stamp sleeve 2) back to its initial position. That is, the stamp 302 has moved upwards to its initial position, and the movable cover 501 is also moved upwards to its initial position (seal retraction). At this time, the motor 201 on the locking mechanism 2 drives the turntable 207 to rotate counterclockwise until the soft connection lock head 2010 on the latch 2011 engages with the soft connection lock head groove 507. The lock head 202 on the latch 2011 passes through the lock head slide groove 504 and engages with the lock head groove 506, thus completing one authorized stamping action.

[0083] The self-inking stamping machine 1 with a soft connection structure of this utility model can also perform stamp changing operations after the stamp is locked and collected. The motor 201 on the stamp locking mechanism 2 drives the turntable 207 to rotate counterclockwise until the stamp sleeve lock 206 unlocks (e.g., Figure 8.5 As shown, the turntable 207 is provided with an unlocking slot 2012. The stamp sleeve 3 is disengaged from the locking mechanism 2, and the outer sleeve 5 is exposed along the stamp movement channel 6, so that the stamp replacement action can be performed. After the stamp 302 is replaced, the stamp sleeve 3 is moved upward along the stamp movement channel 6 until it is connected and fitted with the locking mechanism 2 through the stamp sleeve lock 206, and the stamp replacement action is completed.

[0084] The control panel 8 is located inside the head unit 9 at the upper end of the outer casing 5; the head unit 9 is equipped with a camera 901 and an infrared receiver 902, such as... Figure 5 , Figure 6 As shown.

[0085] The self-inking stamping machine with a flexible connection structure in this embodiment uses the following steps for stamping:

[0086] S1: Set the stamping operation time to within S seconds;

[0087] S2: After receiving the stamping instruction, drive the stamp 302 to move downward along the stamp movement channel 6;

[0088] S3: After the stamp 302 takes ink, continue to drive the stamp 302 to move downward along the stamp movement channel 6 to the stamping piece;

[0089] S4: Complete a stamping within S seconds;

[0090] S5: Drive the stamp 302 to move upward along the stamp movement channel 6 to the initial position, and drive the ink cartridge mechanism 4 to return to the initial position, completing the ink return action.

[0091] In step S2, the seal 302 is in a locked state before receiving the stamping instruction.

[0092] Between step S4 and step S5, a closing instruction will be received.

[0093] It also includes step S6, in which, after receiving a stamp removal instruction, the stamp sleeve 3 disengages from the stamp locking mechanism 2 and moves downward along the stamp movement channel 6, pushing one side of the ink cartridge mechanism 4 to disconnect from the outer sleeve 5, and exiting the outer sleeve 5 to complete one stamp removal.

[0094] In step S6, after the stamp 302 in the stamp sleeve 3 is replaced, the stamp sleeve 3 moves upward along the stamp movement channel 6 and connects with the locking mechanism 2, thereby driving the ink box mechanism 4 to connect with the outer sleeve 5 (the connection can be disconnected, that is, the connecting block 1 40103 and the connecting block 2 40104 are magnetically connected together).

[0095] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
