Description

Technical Field

[0001] The utility model relates to the technical field of machining, in particular to a feeding tooling device. Background Art

[0002] In the field of machining, the feeding tooling device is mainly used for quickly positioning, fixing and feeding workpieces, improving production efficiency and ensuring machining accuracy.

[0003] Taking the end face grinding and polishing of workpieces as an example, in the related art, the workpiece conveying system drives the movement and positioning of the workpiece through structures such as a lead screw assembly, etc. The transmission structure is complex, resulting in a large occupied space. Then, a thrust electric cylinder drives the clamping plate to move to clamp the workpiece. After grinding, the thrust electric cylinder drives the clamping plate to move to loosen the workpiece, and the workpiece is then driven by a servo motor to reset. The overall operation process is also relatively cumbersome, resulting in low production efficiency. Summary of the Utility Model

[0004] In view of this, the utility model provides a feeding tooling device to solve the problems of complex structure, large occupied space and cumbersome operation of the grinding device in the related art, resulting in low production efficiency.

[0005] In the first aspect, the utility model provides a feeding tooling device for installing and feeding workpieces. The feeding tooling device includes:

[0006] A base;

[0007] An installation structure movably installed on the base. The installation structure has a first position and a second position, and the first position and the second position are respectively located at both ends of the movement path. The installation structure is used for installing workpieces;

[0008] A driving structure, including a driving component and an elastic member. The driving component is arranged on the base. The driving end of the driving component drives the installation structure to move from the first position to the second position. One end of the elastic member abuts against the base, and the other end abuts against the installation structure. The elastic member is used to drive the installation structure to reset from the second position to the first position.

[0009] Advantageous Effects: The workpiece is installed on the installation structure, realizing the installation of the workpiece. And the installation structure is movably installed on the base. Therefore, after the installation structure drives the workpiece to move to the second position, there is no need to set other clamping devices to clamp the workpiece, saving operation time and reducing the occupied space. In addition, the driving end of the driving component drives the installation structure to move towards the second position. After the driving end of the driving component resets, the elastic member will automatically drive the installation structure to reset from the second position to the first position. It can be seen that the structure of the driving structure in this embodiment is simpler, so the occupied space is further saved. The feeding tooling device in this embodiment has a simple structure, a relatively small overall occupied space and high operation efficiency.

[0010] In an alternative embodiment, the base includes a bottom plate and a bracket. The bracket and the bottom plate enclose an assembly space, the mounting structure is disposed in the assembly space, and the driving assembly is mounted on the bracket.

[0011] Beneficial effects: The mounting structure is assembled on the base, and then in this assembly space, the mounting structure drives the workpiece to move to the second position under the drive of the driving assembly, and the mounting structure can be reset from the second position to the first position under the drive of the elastic member.

[0012] In an alternative embodiment, the driving assembly includes a micrometer differential head. The micrometer differential head is disposed on the bracket. The micrometer differential head has a driving end, and the driving end passes through the bracket and abuts against the mounting structure.

[0013] Beneficial effects: By rotating the differential barrel of the micrometer differential head, the driving end of the micrometer differential head moves closer to or away from the mounting structure, and then the driving end of the micrometer differential head drives the mounting structure to move to the second position. Moreover, the micrometer differential head enables precise control of the moving distance of the mounting structure, so that the mounting structure moves to the accurate second position.

[0014] In an alternative embodiment, the driving assembly further includes:

[0015] A driving member disposed on the bottom plate;

[0016] A driving gear drivingly connected to the output shaft of the driving member;

[0017] A driven gear drivingly connected to the differential barrel of the micrometer differential head. The driven gear meshes with the driving gear to drive the differential barrel of the micrometer differential head to rotate, and then the driving end drives the mounting structure to move towards the second position.

[0018] Beneficial effects: The driving member drives the driving gear to rotate, and then the driving gear drives the driven gear to rotate. Finally, the driven gear drives the differential barrel of the micrometer differential head to rotate, and the driving end of the micrometer differential head drives the mounting structure, greatly saving labor costs.

[0019] In an alternative embodiment, the ratio of the number of teeth of the driving gear to the number of teeth of the driven gear is less than 1.

[0020] Beneficial effects: The driving precision of the driving end of the micrometer differential head on the mounting structure is higher, and it is beneficial to reduce the structural volume and compact the structural design.

[0021] In an alternative embodiment, the mounting structure includes a mounting seat and a pressing block.

[0022] Beneficial effects: This solution realizes the installation of the workpiece within the installation structure, that is, the workpiece is installed within the installation space formed by the mounting base and the pressing block, and the pressing block presses the workpiece. Then, when the driving structure is driven, the driving end of the driving structure abuts against the pressing block, thereby realizing the driving of the installation structure by the driving end of the driving structure. Moreover, during the driving process, the driving end of the driving structure also provides pressure to the workpiece through the pressing block, further fixing the workpiece and ensuring the stability of the workpiece during subsequent processing.

[0023] In an alternative embodiment, at least two guide posts are provided on the bottom plate. One end of the guide post is connected to the bottom plate, and the other end passes through the mounting base. The mounting base is movably connected to the guide post along the extension direction of the guide post.

[0024] Beneficial effects: The mounting base can slide along the guide post to drive the workpiece to move between the second position and the first position. The guide post plays a guiding and limiting role in the movement of the mounting base. The guide post limits the mounting base in the direction perpendicular to the guide post. Moreover, the driving end of the driving structure limits the pressing block in the direction away from the bottom plate. Thus, after the driving structure drives the workpiece to the second position, the stability of the workpiece during processing is ensured.

[0025] In an alternative embodiment, an elastic member is sleeved outside the guide post. One end of the elastic member abuts against the bottom plate, and the other end abuts against the mounting base.

[0026] Beneficial effects: The guide post plays a limiting role on the elastic member, ensuring that the elastic member drives the installation structure to accurately reset from the second position to the first position, and making the driving of the installation structure by the elastic member more stable.

[0027] In an alternative embodiment, the pressing block is embedded in the installation groove.

[0028] Beneficial effects: There is an interference fit between the pressing block and the mounting base. This installation method of the pressing block and the mounting base is simpler, and can firmly limit the workpiece, improving the structural stability.

[0042] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0043] The following will describe the embodiments of the feeding tooling device of the present utility model in conjunction with Figures 1 to 5 , the embodiments of the feeding tooling device of the present utility model will be described.

[0044] According to an embodiment of the present utility model, on the one hand, a feeding tooling device is provided for mounting and feeding a workpiece 4. As shown in Figure 1 , the feeding tooling device includes a base 1, a mounting structure 2, and a driving structure 3. The mounting structure 2 is movably mounted on the base 1. The mounting structure 2 has a first position and a second position, and the first position and the second position are respectively located at both ends of the moving path. The mounting structure 2 is used for mounting the workpiece 4. The driving structure 3 includes a driving component 31 and an elastic member 32. The driving component 31 is disposed on the base 1. The driving end 3111 of the driving component 31 drives the mounting structure 2 to move from the first position to the second position. One end of the elastic member 32 abuts against the base 1, and the other end abuts against the mounting structure 2. The elastic member 32 is used for driving the mounting structure 2 to reset from the second position to the first position.

[0045] It should be noted that in some embodiments, the first position is the initial position, and the second position is the assembly position. When the mounting structure 2 is in the initial position, the operator can mount the workpiece 4 on the mounting structure 2. When the mounting structure 2 is in the assembly position, the workpiece 4 can be processed, for example, ground or polished by a grinding device.

[0046] In the feeding tooling device of this embodiment, the workpiece 4 is mounted on the mounting structure 2, realizing the mounting of the workpiece 4. Moreover, the mounting structure 2 is movably mounted on the base 1. Therefore, after the mounting structure 2 drives the workpiece 4 to move to the second position, there is no need to set other clamping devices to clamp the workpiece 4, saving operation time and reducing the space occupation. In addition, the driving end 3111 of the driving component 31 drives the mounting structure 2 to move towards the second position. After the driving end 3111 of the driving component 31 resets, the elastic member 32 will automatically drive the mounting structure 2 to reset from the second position to the first position. It can be seen that the structure of the driving structure 3 in this embodiment is simpler, thus further saving the occupied space. The feeding tooling device of this embodiment has a simple structure, a relatively small overall occupied space, and a high operation efficiency.

[0047] The base 1 is adapted to be disposed on the processing platform or the operating platform of the processing equipment, and the processing equipment can be a grinding device. The base 1 is used to carry the mounting structure 2 and the driving structure 3 disposed thereon, so that the feeding tooling device of the present embodiment forms an integral structure, which can be integrally moved and disposed on the required processing equipment, and is flexible and convenient to use with a wide range of applications.

[0048] Further, the base 1 includes a bottom plate 11 and a bracket 12. The bracket 12 is disposed on the bottom plate 11, and the bracket 12 and the bottom plate 11 enclose an assembly space, and the mounting structure 2 is disposed in the assembly space. In order to realize the assembly of the mounting structure 2 to the base 1, and further in the assembly space, the mounting structure 2 can drive the workpiece 4 to move to the second position under the drive of the drive assembly 31, and the mounting structure 2 can be reset from the second position to the first position under the drive of the elastic member 32.

[0049] Specifically, the bottom plate 11 is a rectangular plate-like structure, the bracket 12 is disposed on the upper surface of the bottom plate 11, and a plurality of foot pads 14 are disposed on the surface (lower surface) of the bottom plate 11 facing away from the bracket 12. The plurality of foot pads 14 are spaced apart on the bottom plate 11. The foot pads 14 are preferably made of rubber material, and the specific number and position of the foot pads 14 can be selected according to the area of the lower surface of the bottom plate 11 and the weight of the overall feeding tooling device. In this embodiment, the foot pads 14 are disposed at the four corner positions of the bottom plate 11. When the bottom plate 11 is placed on the processing platform of the processing equipment, the foot pads 14 on the bottom plate 11 are in contact with the processing platform, which ensures the stability of the feeding tooling device on the processing platform, can also prevent wear on the lower surface of the bottom plate 11, and moreover, the bottom plate 11 can be lifted above the processing platform through the foot pads 14, and there is a certain space between the bottom plate 11 and the processing platform, so as to facilitate the processing end of the processing equipment to process the workpiece 4.

[0050] Further, the bracket 12 includes a top plate 121 and two first side plates 122. The two first side plates 122 are spaced apart on opposite sides of the top plate 121. One end of each of the two first side plates 122 is connected to the top plate 121, and the other end of each of the two first side plates 122 is connected to the bottom plate 11. The drive assembly 31 is disposed on the top plate 121 of the bracket 12. The bracket 12 is a similar inverted U-shaped structure. Thus, the bracket 12 and the bottom plate 11 can enclose an assembly space to dispose the mounting structure 2, and the stability of this bracket 12 structure is better, which can stably support the drive assembly 31, and further make the overall tooling device more stable during the processing process, ensuring the processing accuracy of the workpiece 4. Specifically, the end portions (lower ends) of the two first side plates 122 away from the top plate 121 have mounting portions 123 extending along the upper surface of the bottom plate 11. The mounting portions 123 are disposed in contact with the upper surface of the bottom plate 11, and connection holes are formed at corresponding positions of the mounting portions 123 and the bottom plate 11. In this embodiment, fasteners such as screws can be used to realize the installation of the first side plates 122 to the bottom plate 11.

[0051] Further, as Figure 2 shown, the driving assembly 31 includes a micrometer differential head 311. The micrometer differential head 311 is arranged on the bracket 12. The micrometer differential head 311 has a driving end 3111 (i.e., the micrometer screw), and the driving end 3111 passes through the bracket 12 and abuts against the mounting structure 2. In this embodiment, by rotating the differential cylinder 3112 of the micrometer differential head 311, the driving end 3111 of the micrometer differential head 311 can move closer to or away from the mounting structure 2, and further, the driving end 3111 of the micrometer differential head 311 can drive the mounting structure 2 to move to the second position. Moreover, the micrometer differential head 311 can accurately control the moving distance of the mounting structure 2, so that the mounting structure 2 moves to the accurate second position.

[0052] Specifically, the micrometer differential head 311 passes through the top plate 121 in a direction perpendicular to the top plate 121, so that the driving end 3111 of the micrometer differential head 311 abuts against the mounting structure 2. One end of the micrometer differential head 311 away from the driving end 3111 is the differential cylinder 3112, and the differential cylinder 3112 is placed on the top plate 121 for convenient operation. Among them, the micrometer differential head 311 is an existing micrometer tool, and the specific structure and principle of the micrometer differential head 311 are not introduced in detail in this embodiment.

[0053] Further, as Figures 3 - 5 shown, an installation hole 1211 is provided on the top plate 121. The sleeve of the micrometer differential head 311 is inserted through the installation hole 1211 and fixedly arranged to ensure the stability of the micrometer differential head 311 on the top plate 121. The driving end 3111 of the micrometer differential head 311 abuts against the mounting structure 2, and one end of the micrometer differential head 311 away from the driving end 3111 is placed on the top plate 121.

[0054] Further, the driving assembly 31 further includes a driving member 312, a driving gear 313 and a driven gear 314. The driving member 312 is arranged on the bottom plate 11. The axis of the driving gear 313 is connected to the output shaft of the driving member 312. The axis of the driven gear 314 is connected to the differential cylinder 3112 of the micrometer differential head 311. The driven gear 314 meshes with the driving gear 313 to drive the differential cylinder 3112 of the micrometer differential head 311 to rotate, and further, the driving end 3111 of the micrometer differential head 311 drives the mounting structure 2 to move towards the second position. In this embodiment, the driving member 312 is used to drive the driving gear 313 to rotate, and then the driving gear 313 drives the driven gear 314 to rotate. Finally, the driven gear 314 drives the differential cylinder 3112 of the micrometer differential head 311 to rotate, realizing the driving of the mounting structure 2 by the driving end 3111 of the micrometer differential head 311, greatly saving labor costs.

[0055] Further, the bottom of the driving member 312 is disposed on the upper surface of the mounting portion 123 of one of the first side plates 122. The mounting portion 123 of this first side plate 122 is larger in size than the mounting portion 123 of the other first side plate 122, so as to provide space for the driving member 312. This arrangement of the driving member 312 makes full use of the space on the upper surface of the bottom plate 11, making the structure more compact and reducing the occupied space.

[0056] Further, the number of teeth of the driving gear 313 is less than the number of teeth of the driven gear 314. Thus, the driving accuracy of the driving end 3111 of the micrometer differential head 311 for the mounting structure 2 is higher, and it is beneficial to reduce the structural volume and compact the structural design.

[0057] In this embodiment, the driving member 312 is a stepper motor. The driving error of the stepper motor is small, thus ensuring that the mounting structure 2 is driven to the accurate second position.

[0058] Specifically, the specification of the stepper motor in this embodiment is that it rotates one full circle after receiving 20 pulse signals. The number of teeth of the driving gear 313 is 20, and the number of teeth of the driven gear 314 is 50. The specification of the micrometer differential head 311 is that when the differential cylinder 3112 rotates one full circle, the feed amount of the driving end 3111 of the micrometer differential head 311 is 0.05 mm. Therefore, in this embodiment, by using the drive of the stepper motor and the transmission of the driving gear 313 and the driven gear 314, the driving accuracy of the driving end 3111 of the micrometer differential head 311 reaches the micrometer level.

[0059] It should be noted that a stepper motor is a motor that converts an electrical pulse signal into a corresponding angular displacement or linear displacement. For each input pulse signal, the rotor rotates by an angle or advances by one step. Its output angular displacement or linear displacement is proportional to the number of input pulses, and the rotational speed is proportional to the pulse frequency.

[0060] The above-mentioned stepper motor has a specification of rotating one full circle after receiving 20 pulse signals, which corresponds to the 20 teeth of the driving gear 313, facilitating the control and measurement of the rotational speed of the driving wheel. It can be understood that the number of pulse signals received by the above-mentioned stepper motor for one full rotation can also be a multiple of 20, such as 40, 60, etc.

[0061] When grinding the end face of the workpiece 4, first drive the workpiece 4 to the accurate second position, and then continue to drive the workpiece 4 to feed, that is, grind the workpiece 4 while feeding, thereby achieving the grinding and polishing of the workpiece 4. The above solution achieves a driving accuracy of the driving end 3111 of the micrometer differential head 311 reaching the micrometer level, and further enables the feed amount of the workpiece 4 during the grinding process to reach the micrometer level. Therefore, the grinding process of the end face of the workpiece 4 is accurately controlled, effectively ensuring the surface finish of the end face of the workpiece 4.

[0062] Further, the mounting structure 2 includes a mounting base 21 and a pressing block 22. The mounting base 21 is provided with a mounting groove, and the pressing block 22 is detachably mounted on the top of the mounting groove. The workpiece 4 is accommodated in the mounting space 23 formed by the mounting base 21 and the pressing block 22. The driving end 3111 of the driving structure 3 abuts against the side of the pressing block 22 away from the workpiece 4. This solution realizes the mounting of the workpiece 4 in the mounting structure 2, that is, the workpiece 4 is mounted in the mounting space 23 formed by the mounting base 21 and the pressing block 22, and the pressing block 22 presses the workpiece 4. Then, when the driving structure 3 drives, the driving end 3111 of the driving structure 3 abuts against the pressing block 22, thereby realizing the driving of the mounting structure 2 by the driving end 3111 of the driving structure 3. Moreover, during the driving process, the driving end 3111 of the driving structure 3 also provides pressure to the workpiece 4 through the pressing block 22, so that the workpiece 4 is further fixed, ensuring the stability of the workpiece 4 during subsequent processing.

[0063] Further, the mounting base 21 includes a base 211, two second side plates 212, and two mounting plates 213. The two second side plates 212 are spaced apart from each other on opposite sides of the base 211. One end of each of the two second side plates 212 is connected to the base 211, and the other end is respectively connected to a mounting plate 213. The two mounting plates 213 extend away from each other. Optionally, the extending direction is parallel to the lower surface of the top plate 121 for cooperation with the top plate 121.

[0064] A channel 2111 is provided on the base 211, and the channel 2111 communicates the first position and the second position of the workpiece 4. When the workpiece 4 is mounted in the mounting space 23, the part 41 to be processed of the workpiece 4 extends out of the channel 2111 and reaches the second position. Thus, the structure of this mounting base 21 realizes the formation of the above-mentioned mounting groove at the top of the mounting base 21. The side walls of the mounting groove are the two second side plates 212, and the mounting groove in the mounting base 21 forms the above-mentioned mounting space 23, that is, the mounting space 23 is located between the two second side plates 212. That is to say, the structure of this mounting base 21 forms a connected mounting groove and mounting space 23, and the mounting groove is located above the mounting space 23. Moreover, both sides of the mounting space 23 in the horizontal direction communicate with the outside of the mounting base 21. Thus, after the workpiece 4 is placed in the mounting base 21, the position of the workpiece 4 can be adjusted by using the two positions on both sides where the mounting space 23 communicates with the outside of the mounting base 21, realizing the precise positioning of the workpiece 4 in the mounting base 21.

[0065] In this embodiment, the mounting groove is a through groove that is open at the top of the mounting base 21 and penetrates in the horizontal direction.

[0066] In addition, taking a partial structure of the workpiece 4 as an endoscope as an example, the workpiece 4 includes an insertion tube of the endoscope and a swivel joint provided at the end of the insertion tube. An optical fiber is disposed along the length direction inside the insertion tube, and the optical fiber is bent at the position of the swivel joint and extends out of the swivel joint. It is necessary to grind the part of the optical fiber extending out of the swivel joint. In some embodiments, the bending angle is 90°. It can be understood that in addition to 90°, it can also be other angles close to 90°, for example, any other angle within the range of 80° to 100°. In the above structural solution of the mounting seat 21, the swivel joint can be placed in the mounting space 23 of the mounting seat 21, and the part of the optical fiber extending out of the swivel joint extends out of the channel 2111 of the base 211, and then the insertion tube connected to the swivel joint passes through between the two second side plates 212, that is, the connected insertion tube and swivel joint are arranged in the mounting groove along the through direction of the mounting groove. Thus, there is no need to disassemble the insertion tube and the swivel joint and then place the swivel joint in the mounting space 23 of the mounting seat 21 to grind the optical fiber, thereby simplifying the overall processing process of the workpiece 4 and improving the production efficiency.

[0067] Further, at least two guide posts 13 are provided on the bottom plate 11. One end of the guide post 13 is connected to the bottom plate 11, and the other end of the guide post 13 passes through the mounting seat 21. The mounting seat 21 is in sliding fit with the guide post 13. That is, the mounting seat 21 can slide along the guide post 13 to drive the workpiece 4 to move between the second position and the first position. The guide post 13 plays a role of guiding and limiting the movement of the mounting seat 21. The guide post 13 limits the mounting seat 21 in the direction perpendicular to the guide post 13. And the driving end 3111 of the driving structure 3 limits the pressing block 22 in the direction away from the bottom plate 11. Thus, after the driving structure 3 drives the workpiece 4 to move to the second position, the stability of the workpiece 4 during processing is ensured.

[0068] Specifically, the number of the guide posts 13 in this embodiment is four, and the four guide posts 13 are arranged in a rectangular array. Positioning through holes 2131 corresponding to the guide posts 13 are provided on the mounting plate 213 of the mounting seat 21, and the guide posts 13 are inserted into the positioning through holes 2131, ensuring the stability of the movement of the mounting structure 2.

[0069] Further, an elastic member 32 is sleeved outside the guide post 13. One end of the elastic member 32 abuts against the bottom plate 11, and the other end abuts against the mounting seat 21. Thus, the guide post 13 plays a role of limiting the elastic member 32, ensuring that the elastic member 32 drives the mounting structure 2 to accurately reset from the second position to the first position, and making the driving of the elastic member 32 on the mounting structure 2 more stable.

[0070] Specifically, the elastic member 32 is a spring. When the driving assembly 31 drives the mounting structure 2 to move downward to the second position, the elastic member 32 is compressed. After the machining is completed, when the driving force of the driving assembly 31 on the mounting structure 2 is withdrawn, the mounting structure 2 returns to the first position under the action of the restoring force of the elastic member 32.

[0071] Further, the pressing block 22 is embedded in the mounting groove. That is, an interference fit is formed between the pressing block 22 and the mounting base 21. This mounting method of the pressing block 22 and the mounting base 21 is simpler and can firmly limit the workpiece 4, improving the structural stability.

[0072] Further, a through hole 111 is provided at the position of the base plate 11 corresponding to the workpiece 4, and the through hole 111 corresponds to the position of the channel 2111. When the workpiece 4 is in the second position, the to-be-machined part 41 of the workpiece 4 extends out of the channel 2111 and the through hole 111 in sequence. It can be understood that the entire mounting structure 2 can also extend out of the through hole 111. The base plate 11 of this embodiment can ensure the stability of the entire tooling device. On this basis, the setting of the through hole 111 on the base plate 11 enables the to-be-machined part 41 of the workpiece 4 to extend out of the through hole 111, so that the output end of the processing equipment can machine the to-be-machined part 41 of the workpiece 4.

[0073] Taking the grinding process of the workpiece 4 as an example, the operation process of the feeding tooling device of this embodiment is described below:

[0074] The base plate 11 of the feeding tooling device is installed on the processing platform of the grinding equipment;

[0075] Take out the pressing block 22 from the mounting groove of the mounting base 21 to open the mounting structure 2, then place the workpiece 4 in the mounting space 23 of the mounting structure 2, and place the to-be-machined part 41 of the workpiece 4 at the channel 2111. Then embed the pressing block 22 into the mounting groove, and the positioning and assembly of the workpiece 4 is completed. At this time, the workpiece 4 is in the first position;

[0076] The driving structure 3 drives the differential cylinder 3112 of the micrometer differential head 311 to rotate, so that the driving end 3111 of the micrometer differential head 311 abuts against the upper surface of the pressing block 22, and then pushes the mounting structure 2 to move to the second position. At this time, the entire mounting structure 2 extends out of the through hole 111 of the base plate 11;

[0077] The operating end of the grinding equipment grinds the to-be-machined part 41 of the workpiece 4. In some embodiments, the operating end of the grinding equipment is a grinding disc. It can be understood that it can also be a grinding belt.

[0078] After the machining is completed, the driving structure 3 drives the differential cylinder 3112 of the micrometer differential head 311 to rotate in the reverse direction, so that the driving end 3111 of the micrometer differential head 311 is reset, and the mounting structure 2 is reset from the second position to the first position under the action of the elastic member 32;

[0079] Open the installation structure 2 and take out the workpiece 4 after grinding.

[0080] Although embodiments of the present utility model have been described with reference to the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present utility model, and such modifications and variations fall within the scope defined by the appended claims.
