Description

Technical Field

[0001] The invention belongs to the technical field of turning and grooving, and in particular relates to a parts cutting device for metal processing. Background Art

[0002] For some parts that have been adapted in terms of size, especially samples or non-standard shaft parts that are not mass-produced, if these parts need to be reduced in weight, they are often processed by turning and cutting annular grooves on the surface of the parts; when grooving existing parts to reduce weight, the following aspects need to be noted:

[0003] First, the depth of the groove should be strictly controlled and conservatively selected to avoid excessive impact on the strength of the part due to stress concentration;

[0004] Second, the spacing between the grooves should be appropriate. Generally speaking, when the depth of the grooves is determined, the distribution of the grooves should be relatively dense at the thicker positions of the shaft parts to achieve better weight reduction effects; the distribution of the grooves should be relatively sparse at the thinner positions of the shaft parts to reduce the impact on the strength of the parts.

[0005] Based on the above requirements, there is still a problem faced during mechanized production. Since the central axis of shaft parts is fixed, how to maintain the same groove depth when the diameter changes is also a problem that the present invention urgently needs to solve. Summary of the invention

[0006] In view of the above situation, in order to overcome the defects of the prior art, the present invention proposes a part cutting device for metal processing that can adaptively change the grooving density according to the diameter of the part; on the one hand, through the rotational drive of the one-way transmission component, the reciprocating extension and contraction of the push rod that controls the opening and closing of the tool feed can be utilized to realize intermittent driving of the beam body, which not only simplifies the structure, but also realizes the mutual action coordination between the tool advance and retreat and the intermittent sliding of the beam body; on the other hand, through the adaptive spacing type transverse movement mechanism to sense the diameter of the stepped shaft parts, when the diameter of the stepped shaft parts at the grooving position changes, the sliding amplitude of the beam body can be adaptively changed, thereby realizing the technical effect of automatically adjusting the grooving density.

[0007] The technical solution adopted by the present invention is as follows: The present invention proposes a part cutting device for metal processing, including an adaptive spacing type transverse movement mechanism, a variable depth type grooving mechanism and an installation clamping mechanism, the adaptive spacing type transverse movement mechanism is arranged on a fixed side plate, and the variable depth type grooving mechanism is arranged on the adaptive spacing type transverse movement mechanism.

[0008] Furthermore, the adaptive spacing type transverse movement mechanism includes a beam assembly, a one-way transmission assembly and an opening and closing control assembly, the beam assembly is arranged on the fixed side plate, the one-way transmission assembly is arranged on the beam assembly, and the opening and closing control assembly is arranged on the beam assembly.

[0009] Through the reciprocating transmission of the adaptive spacing transverse movement mechanism, it can automatically control its intermittent sliding in the process of reciprocating lifting and lowering of the opening and closing control push rod according to the connection and interruption of power transmission, and can automatically change the amplitude of each sliding according to the diameter of the part at the slotting position, thereby realizing adaptive dynamic control of the slotting density.

[0010] Preferably, the crossbeam assembly includes a crossbeam body, a crossbeam slider and a crossbeam slide rail, the crossbeam slide rail is fixedly connected to the fixed side plate, the crossbeam slider is snap-fitted and slidably arranged on the crossbeam slide rail, there is sliding resistance between the crossbeam slider and the crossbeam slide rail, the crossbeam body is arranged on the crossbeam slider, a sliding groove is arranged on the crossbeam body, an intermediate partition beam is arranged in the middle position of the crossbeam body, and a rotating circular sleeve is arranged at one end of the crossbeam body.

[0011] As a further preferred embodiment of the present invention, the one-way transmission assembly includes a transmission shaft and a transmission sleeve, the transmission shaft is provided with a round shaft portion, the transmission shaft is rotatably arranged in a rotating round sleeve through the round shaft portion, the transmission shaft is also provided with an optical axis portion, the end of the optical axis portion is provided with an external ratchet portion, the transmission sleeve is provided with a smooth hole portion, the transmission sleeve is rotatably arranged on the optical axis portion through the smooth hole portion, one end of the transmission sleeve is also provided with an inner ratchet portion cooperating with the outer ratchet portion, and the outer surface of the transmission sleeve is provided with an external thread groove.

[0012] The transmission sleeve can drive the transmission shaft unidirectionally, and the sliding resistance between the crossbeam slider and the crossbeam slide rail is greater than the relative rotational resistance between the transmission sleeve and the transmission shaft when the opening and closing control push rod rises. Therefore, when the opening and closing control push rod rises, the transmission sleeve cannot drive the transmission shaft to rotate through the cooperation between the outer ratchet part and the inner ratchet part; when the opening and closing control push rod descends, the transmission sleeve can drive the transmission shaft to rotate through the cooperation between the outer ratchet part and the inner ratchet part; in conjunction with the gear rack transmission of the drive assembly, the technical effect of intermittently driving the crossbeam body to slide is achieved.

[0013] Preferably, the opening and closing control assembly includes an opening and closing control push rod, a lifting control console, a sensing slider, a control connecting rod, a vertical guide rod and a dislocation spring, the opening and closing control push rod is arranged on the middle partition beam, the vertical guide rod is arranged on the telescopic part of the opening and closing control push rod, the lifting control console is snap-fitted and slidably arranged on the vertical guide rod, the dislocation spring is arranged between the telescopic part of the opening and closing control push rod and the lifting control console, the two ends of the lifting control console are symmetrically provided with console hinge shafts, the sensing slider is snap-fitted and slidably arranged in a sliding groove on one side of the beam body, the sensing slider is provided with a ball nut part, the external threaded groove and the ball nut part are threadedly connected, the outside of the ball nut part is symmetrically provided with slider hinge shafts, wherein the two ends of the two control connecting rods are respectively hinged to the slider hinge shaft and the console hinge shaft.

[0014] The threaded cooperation between the ball nut and the external thread groove can drive the transmission sleeve to rotate when the sensing slider slides in the sliding groove. Moreover, due to the different diameters of the stepped shaft parts, even if the opening and closing control push rod reciprocates and telescopes with the same amplitude, the actual lifting amplitude of the lifting control console will change with the change in the diameter of the stepped shaft parts, thereby achieving the technical effect of adaptively adjusting the slot density.

[0015] Furthermore, the variable depth grooving mechanism comprises a diameter sensing component and a rotary grooving component, wherein the diameter sensing component is arranged on the opening and closing control component, and the rotary grooving component is slidably arranged on the crossbeam component.

[0016] When the diameter sensing component and the rotary slotting component reciprocate and open and contract, on the one hand, they can sense the current diameter of the stepped shaft parts through the sensing bracket, and on the other hand, they can cut and slot the stepped shaft parts through the high-speed rotating grinding wheel. Since the sliding of the sensing slider and the slotting slider are linked, when the diameter of the stepped shaft parts changes, causing the sliding amplitude of the sensing slider to change, the grinding wheel can still ensure that the cutting depth remains unchanged.

[0017] Preferably, the diameter sensing component comprises a sensing bracket and a sensing roller, the sensing bracket is fixedly connected to the bottom of the sensing slider, and the sensing roller is rotatably disposed in the sensing bracket.

[0018] As a further preferred embodiment of the present invention, the rotating slotting assembly includes a slotting slider, a slotting slide plate, a slotting bracket, a slotting motor and a grinding wheel. The slotted slider is slidably engaged in a sliding groove on the other side of the beam body. The slotted slider is provided with an adjusting slide groove. The slotted slide plate can be adjusted in the adjusting slide groove. A slider hinge boss is provided on the top of the slotted slider. The other two ends of the control connecting rods are respectively hinged on the slider hinge boss and the console hinge shaft. The slotted bracket is fixedly connected to the bottom of the slotted slide plate. The slotted motor is arranged on the slotted bracket. The grinding wheel is arranged on the output shaft of the slotted motor.

[0019] By manually adjusting the position of the slotting slide in the slotting slide, the depth of the cutting slot can be actively adjusted and preset.

[0020] Furthermore, the installation and clamping mechanism includes a base plate, a clamping assembly and a driving assembly, the base plate is provided with a fixed side plate, the clamping assembly is arranged on the base plate, and the driving assembly is arranged on the base plate.

[0021] Preferably, the clamping assembly comprises a clamping rotating seat, a three-jaw chuck and a stepped shaft part, the clamping rotating seat is arranged on a base plate, the three-jaw chuck is rotatably arranged in the clamping rotating seat, and the stepped shaft part is engaged in the three-jaw chuck.

[0022] By slowly rotating the stepped shaft parts, the grinding wheel can groove the stepped shaft parts in a full circle. Since the width of the induction roller is greater than the width of the groove, the position of the induction roller can remain stable during the rotation of the stepped shaft parts.

[0023] As a further preferred embodiment of the present invention, the driving assembly includes a rotating motor, a fixed rack and a sliding gear, the rotating motor is arranged on the base plate, the output shaft of the rotating motor is connected to one of the three-jaw chucks, the fixed rack is fixed to the fixed side plate, the sliding gear is arranged on the circular shaft portion, and the fixed rack and the sliding gear are meshed for transmission.

[0024] The beneficial effects achieved by the present invention using the above structure are as follows:

[0025] (1) Through the reciprocating transmission of the adaptive spacing transverse movement mechanism, the intermittent sliding of the mechanism can be automatically controlled according to the connection and interruption of power transmission during the reciprocating lifting and lowering of the opening and closing control push rod, and the amplitude of each sliding can be automatically changed according to the diameter of the part at the slotting position, thereby realizing adaptive dynamic control of the slotting density.

[0026] (2) The transmission sleeve can drive the transmission shaft unidirectionally, and the sliding resistance between the crossbeam slider and the crossbeam slide rail is greater than the relative rotational resistance between the transmission sleeve and the transmission shaft when the opening and closing control push rod rises. Therefore, when the opening and closing control push rod rises, the transmission sleeve cannot drive the transmission shaft to rotate through the cooperation between the outer ratchet part and the inner ratchet part; and when the opening and closing control push rod descends, the transmission sleeve can drive the transmission shaft to rotate through the cooperation between the outer ratchet part and the inner ratchet part; in combination with the gear rack transmission of the drive assembly, the technical effect of intermittently driving the crossbeam body to slide is achieved.

[0027] (3) The threaded fit between the ball nut and the external threaded groove enables the sensing slider to drive the transmission sleeve to rotate when it slides in the sliding groove. Furthermore, due to the different diameters of the stepped shaft parts, even if the opening and closing control push rod reciprocates with the same amplitude of telescopic movement, the actual lifting amplitude of the lifting control console will change with the change in the diameter of the stepped shaft parts, thereby achieving the technical effect of adaptively adjusting the slot density.

[0028] (4) When the diameter sensing component and the rotary slotting component are reciprocatingly opened and contracted, on the one hand, they can sense the current diameter of the stepped shaft parts through the sensing bracket, and on the other hand, they can cut and slot the stepped shaft parts through the high-speed rotating grinding wheel. Since the sliding of the sensing slider and the slotting slider are linked, when the sliding amplitude of the sensing slider changes due to the change in the diameter of the stepped shaft parts, the grinding wheel can still ensure that the cutting depth remains unchanged.

[0029] (5) By manually adjusting the position of the slotting slide in the slotting slider, the depth of the cutting slot can be actively adjusted and preset.

[0030] (6) Through the slow rotation of the stepped shaft part, the grinding wheel can make a full circle of grooves on the stepped shaft part. Since the width of the induction roller is larger than the width of the groove, the position of the induction roller can remain stable during the rotation of the stepped shaft part.

[0045] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0046] In the description of the present invention, it should be understood that terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “top”, “bottom”, “inside” and “outside” indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0047] like Figure 1 to Figure 12 As shown, the present invention proposes a part cutting device for metal processing, including an adaptive spacing type transverse movement mechanism 1, a variable depth type grooving mechanism 2 and an installation clamping mechanism 3, wherein the adaptive spacing type transverse movement mechanism 1 is arranged on a fixed side plate 40, and the variable depth type grooving mechanism 2 is arranged on the adaptive spacing type transverse movement mechanism 1.

[0048] The adaptive spacing transverse movement mechanism 1 includes a beam assembly 4, a one-way transmission assembly 5 and an opening and closing control assembly 6, the beam assembly 4 is arranged on the fixed side plate 40, the one-way transmission assembly 5 is arranged on the beam assembly 4, and the opening and closing control assembly 6 is arranged on the beam assembly 4.

[0049] Through the reciprocating transmission of the adaptive spacing transverse movement mechanism 1, it can automatically control its intermittent sliding in the process of reciprocating lifting and lowering of the opening and closing control push rod 12 according to the connection and interruption of power transmission, and can automatically change the amplitude of each sliding according to the diameter of the part at the slotting position, thereby realizing adaptive dynamic control of the slotting density.

[0050] The crossbeam assembly 4 includes a crossbeam body 7, a crossbeam slider 8 and a crossbeam slide rail 9. The crossbeam slide rail 9 is fixedly connected to the fixed side plate 40. The crossbeam slider 8 is slidably arranged on the crossbeam slide rail 9. There is sliding resistance between the crossbeam slider 8 and the crossbeam slide rail 9. The crossbeam body 7 is arranged on the crossbeam slider 8. A sliding groove 16 is arranged on the crossbeam body 7. An intermediate partition beam 17 is arranged in the middle position of the crossbeam body 7. A rotating circular sleeve 18 is arranged at one end of the crossbeam body 7.

[0051] The one-way transmission assembly 5 includes a transmission shaft 10 and a transmission sleeve 11. The transmission shaft 10 is provided with a round shaft portion 19, and the transmission shaft 10 is rotatably arranged in the rotating circular sleeve 18 through the round shaft portion 19. The transmission shaft 10 is also provided with an optical axis portion 20, and the end of the optical axis portion 20 is provided with an external ratchet portion 21. The transmission sleeve 11 is provided with a smooth hole portion 22, and the transmission sleeve 11 is rotatably arranged on the optical axis portion 20 through the smooth hole portion 22. One end of the transmission sleeve 11 is also provided with an inner ratchet portion 23 that cooperates with the outer ratchet portion 21, and the outer surface of the transmission sleeve 11 is provided with an external thread groove 24.

[0052] The transmission sleeve 11 can drive the transmission shaft 10 unidirectionally, and the sliding resistance between the crossbeam slider 8 and the crossbeam slide rail 9 is greater than the relative rotation resistance between the transmission sleeve 11 and the transmission shaft 10 when the opening and closing control push rod 12 rises. Therefore, when the opening and closing control push rod 12 rises, the transmission sleeve 11 cannot drive the transmission shaft 10 to rotate through the cooperation between the outer ratchet portion 21 and the inner ratchet portion 23; and when the opening and closing control push rod 12 descends, the transmission sleeve 11 can drive the transmission shaft 10 to rotate through the cooperation between the outer ratchet portion 21 and the inner ratchet portion 23; in conjunction with the gear rack transmission of the drive assembly 39, the technical effect of intermittently driving the crossbeam body 7 to slide is achieved.

[0053] The opening and closing control assembly 6 includes an opening and closing control push rod 12, a lifting control console 13, a sensing slider 14, a control link 15, a vertical guide rod 49 and a dislocation spring 50. The opening and closing control push rod 12 is arranged on the middle partition beam 17, the vertical guide rod 49 is arranged on the telescopic part of the opening and closing control push rod 12, the lifting control console 13 is engaged and slidably arranged on the vertical guide rod 49, the dislocation spring 50 is arranged between the telescopic part of the opening and closing control push rod 12 and the lifting control console 13, and the two ends of the lifting control console 13 are symmetrically provided with a console hinge shaft 25, the sensing slider 14 is engaged and slidably arranged in the sliding groove 16 on one side of the beam body 7, the sensing slider 14 is provided with a ball nut part 26, the external thread groove 24 is threadedly connected to the ball nut part 26, and the outside of the ball nut part 26 is symmetrically provided with a slider hinge shaft 27, wherein the two ends of the two control links 15 are respectively hinged to the slider hinge shaft 27 and the control console hinge shaft 25.

[0054] The threaded cooperation between the ball nut portion 26 and the external thread groove 24 can drive the transmission sleeve 11 to rotate when the sensing slider 14 slides in the sliding groove 16, and due to the different diameters of the stepped shaft parts 43, even if the opening and closing control push rod 12 reciprocates and telescopes with the same amplitude, the actual lifting and lowering amplitude of the lifting control console 13 will also change with the change in the diameter of the stepped shaft parts 43, thereby achieving the technical effect of adaptively adjusting the slotting density.

[0055] The variable depth grooving mechanism 2 comprises a diameter sensing component 28 and a rotary grooving component 29 . The diameter sensing component 28 is arranged on the opening and closing control component 6 , and the rotary grooving component 29 is slidably arranged on the crossbeam component 4 .

[0056] When the diameter sensing component 28 and the rotating slotting component 29 are reciprocatingly opened and contracted, on the one hand, they can sense the current diameter of the stepped shaft parts 43 through the sensing bracket 30, and on the other hand, they can cut and slot the stepped shaft parts 43 through the high-speed rotating grinding wheel 35. Since the sliding of the sensing slider 14 and the slotting slider 32 are linked, when the diameter of the stepped shaft parts 43 changes, causing the sliding amplitude of the sensing slider 14 to change, the grinding wheel 35 can still ensure that the cutting depth remains unchanged.

[0057] The diameter sensing assembly 28 includes a sensing bracket 30 and a sensing roller 31 . The sensing bracket 30 is fixedly connected to the bottom of the sensing slider 14 , and the sensing roller 31 is rotatably disposed in the sensing bracket 30 .

[0058] The rotating slotting assembly 29 includes a slotting slider 32, a slotting slide plate 48, a slotting bracket 33, a slotting motor 34 and a grinding wheel 35. The slotting slider 32 is engaged and slidably arranged in the sliding groove 16 on the other side of the beam body 7. The slotting slider 32 is provided with an adjustment slide groove, and the slotted slide plate 48 is adjustably arranged in the adjustment slide groove. The top of the slotted slider 32 is provided with a slider hinge boss 47, and the two ends of the other two control connecting rods 15 are respectively hinged to the slider hinge boss 47 and the console hinge shaft 25. The slotting bracket 33 is fixedly connected to the bottom of the slotting slide plate 48, the slotting motor 34 is arranged on the slotting bracket 33, and the grinding wheel 35 is arranged on the output shaft of the slotting motor 34.

[0059] By manually adjusting the position of the slotting slide plate 48 in the slotting slide block 32, the depth of the slotting can be actively adjusted and preset.

[0060] The mounting clamping mechanism 3 comprises a base plate 37 , a clamping assembly 38 and a driving assembly 39 . A fixed side plate 40 is provided on the base plate 37 . The clamping assembly 38 is arranged on the base plate 37 . The driving assembly 39 is arranged on the base plate 37 .

[0061] The clamping assembly 38 includes a clamping rotating seat 41 , a three-jaw chuck 42 and a stepped shaft part 43 . The clamping rotating seat 41 is arranged on the base plate 37 , the three-jaw chuck 42 is rotatably arranged in the clamping rotating seat 41 , and the stepped shaft part 43 is engaged in the three-jaw chuck 42 .

[0062] By slowly rotating the stepped shaft part 43, the grinding wheel 35 can groove the stepped shaft part 43 in a full circle. Since the width of the induction roller 31 is larger than the width of the groove, the position of the induction roller 31 can remain stable during the rotation of the stepped shaft part 43.

[0063] The driving assembly 39 includes a rotating motor 44, a fixed rack 45 and a sliding gear 46. The rotating motor 44 is arranged on the base plate 37. The output shaft of the rotating motor 44 is connected to one of the three-jaw chucks 42. The fixed rack 45 is fixedly connected to the fixed side plate 40. The sliding gear 46 is arranged on the circular shaft portion 19. The fixed rack 45 and the sliding gear 46 are meshed for transmission.

[0064] When in use, the user first needs to clamp and fix the stepped shaft part 43 with the three-jaw chuck 42, and then adjust and preset the slotting depth by adjusting the position of the slotting slide 48 in the slotting slide 32; then start the slotting motor 34 and the rotating motor 44, and the high-speed rotating grinding wheel 35 does not contact the stepped shaft part 43 in the initial state;

[0065] Then, the opening and closing control push rod 12 is controlled to extend. While the opening and closing control push rod 12 brings the lifting console 13 up, it will slide toward the middle partition beam 17 through the control connecting rod 15 with the sensing slider 14 and the slotted slider 32. During the sliding process, the grinding wheel 35 will first contact the stepped shaft part 43. At this time, the opening and closing control push rod 12 continues to extend, but the lifting console 13 will slide relative to the vertical guide rod 49. At this time, the lifting console 13 provides the lifting force through the elastic force of the offset spring 50; therefore, even if the diameter of the stepped shaft part 43 is different, the opening and closing control push rod 12 can still reciprocate and extend according to the set interval period and amplitude;

[0066] Since the stepped shaft part 43 itself is also rotating slowly, the grooving process is performed in a full circle and the depth is gradually increased until the induction roller 31 contacts the stepped shaft part 43, and then the grinding wheel 35 stops feeding and the grooving is completed;

[0067] During the sliding of the sensing slider 14 toward the middle partition beam 17, since the sliding resistance between the cross beam slider 8 and the cross beam slide rail 9 is greater than the relative rotation resistance between the transmission sleeve 11 and the transmission shaft 10, when the sensing slider 14 slides toward the middle partition beam 17, through the cooperation between the outer ratchet portion 21 and the inner ratchet portion 23, the transmission sleeve 11 will only idle and cannot drive the transmission shaft 10 to rotate.

[0068] After the slotting is completed, the opening and closing control push rod 12 retracts and brings the lifting console 13 down through the tension of the offset spring 50. While the lifting console 13 is descending, the sensing slider 14 and the slotting slider 32 are pushed away from the middle partition beam 17 through the control connecting rod 15.

[0069] When the sensing slider 14 slides away from the middle partition beam 17, due to the cooperation between the outer ratchet portion 21 and the inner ratchet portion 23, the transmission sleeve 11 can rotate with the transmission shaft 10. When the transmission shaft 10 rotates, the meshing transmission of the fixed rack 45 and the sliding gear 46 can overcome the resistance between the beam slider 8 and the beam slide rail 9 and push the beam body 7 to slide laterally.

[0070] Through the above steps, when the lifting console 13 rises, the sensing slider 14 and the slotted slider 32 are driven to slide toward the middle partition beam 17 through the control connecting rod 15. At this time, the transmission shaft 10 does not rotate and the beam body 7 does not slide; when the lifting console 13 descends, the sensing slider 14 and the slotted slider 32 are driven to slide away from the middle partition beam 17 through the control connecting rod 15. At this time, the transmission sleeve 11 can rotate with the transmission shaft 10, and through the meshing transmission of the fixed rack 45 and the sliding gear 46, it can slide with the beam body 7, thereby realizing the change of the slot position.

[0071] Since the sensing slider 14 and the slotting slider 32 slide synchronously, when the diameter of the stepped shaft part 43 changes, the limit position of the sensing roller 31 changes, and the limit position of the grinding wheel 35 also changes, thereby ensuring that the depth of the slotting is consistent.

[0072] When the diameters of the stepped shaft parts 43 are different, since the extreme position of the sensing slider 14 is the position when the sensing roller 31 and the stepped shaft parts 43 are in contact, the minimum distance between the sensing slider 14 and the middle partition beam 17 will also be different. At this time, the rotation angle of the transmission sleeve 11 in the reset stage will also change; specifically, the larger the diameter of the stepped shaft parts 43, the smaller the lateral displacement of the sensing slider 14, and the smaller the lateral displacement of the beam body 7, and the denser the grooves; the smaller the diameter of the stepped shaft parts 43, the larger the lateral displacement of the sensing slider 14, and the larger the lateral displacement of the beam body 7, and the sparser the grooves.

[0073] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0074] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
