Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0043] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0044] See also Figures 1 to 3 , an arc adjustment mechanism provided in an embodiment of the present invention, is applied to a display screen bracket having at least two lateral frames, the display screen bracket is used to load a display screen unit 500, a display screen unit 500 is formed by hingedly connecting multiple display modules 510 in sequence, a display screen bracket and a display screen unit 500 are assembled into a display screen box, and a display screen box or multiple display screen boxes are a display device.

[0045] Specifically, the arc adjustment mechanism includes a hinge assembly 200 and a limit assembly 300, wherein two lateral frames 100 are arranged in parallel, wherein one lateral frame 100 is fixedly arranged on the back side of the display module 510 at one end of the display screen unit 500, and the other lateral frame 100 is fixedly arranged on the back side of the display module 510 at the other end of the display screen unit 500. The hinge assembly 200 includes a plurality of hinge modules 210, and the hinge modules 210 are hingedly connected in sequence. The hinge module 210 at one end of the hinge assembly 200 is connected to one lateral frame 100, and the hinge module 210 at the other end of the hinge assembly 200 is connected to another lateral frame 100. Each hinge module 210 is used to be respectively assembled on the back side of each display module 510. It can be seen that the lateral frame 100 and the front side of the hinge assembly 200 are used to load a display screen unit 500. Both ends of the limiting component 300 are connected to the lateral frames 100 respectively, and the limiting component 300 is configured to be telescopically adjustable to limit the distance between the two lateral frames 100 .

[0046] During use, the staff controls the angle between the hinge modules 210 and the hinge modules 210, so that the hinge assembly 200 is transformed from a straight line arrangement to an arc curve arrangement. Accordingly, the display unit 500 is deformed synchronously with the hinge assembly 200, that is, the display unit 500 is bent from a straight screen to an arc curved screen (refer to Figure 4 and Figure 5 ); or, the hinge assembly 200 is converted from a linear arrangement to an S-shaped arrangement, and accordingly, the display unit 500 is deformed synchronously with the hinge assembly 200, that is, the display unit 500 is bent from a straight screen to an S-shaped curved screen (refer to Figure 6 ), of course, the display screen unit 500 may also be bent into other shapes.

[0047] In the process of rotating and adjusting the hinge assembly 200, the staff telescopically adjusts the length of the limit assembly 300, thereby adjusting the distance between the two lateral frames 100. Accordingly, the distance between the two ends of the hinge assembly 200 is effectively controlled, and therefore, the curvature of the display screen unit 500 is effectively controlled. Specifically, if the staff reduces the length of the limit assembly 300, the curvature of the hinge assembly 200 is effectively increased, and accordingly, the curvature of the display screen unit 500 is effectively increased; if the staff increases the length of the limit assembly 300, the curvature of the hinge assembly 200 is effectively reduced, and the curvature of the display screen unit 500 is effectively reduced. It can be seen from the above that the curvature of the display screen unit 500 is effectively controlled by adjusting the length of the limit assembly 300. Therefore, the hinge assembly 200 cooperates with the limit assembly 300, and the staff can conveniently bend the display screen unit 500 into the required curvature.

[0048] In some embodiments, reference Figure 3 and Figure 7 The limit assembly 300 includes at least two telescopic parts (the sleeve body 310 and the telescopic rod 320 described below), and the telescopic parts are slidably arranged in sequence, such as adjacent telescopic parts are connected in a sleeve manner. The telescopic part at one end of the limit assembly 300 is connected to one lateral frame 100, and the telescopic part at the other end of the limit assembly 300 is connected to the other lateral frame 100; at the same time, a locking structure or other structure is arranged between the adjacent telescopic parts, and after the adjacent telescopic parts are relatively slid and adjusted, the locking structure or other structure is used to maintain the positions of the two telescopic parts.

[0049] Among them, the number of telescopic parts can be set to two, three or four, etc., and the specific number is set according to actual needs. For example, the longer the length of the hinge assembly 200, the more telescopic parts can be set accordingly, and the longer the adjustable length distance is, so that it can adapt to the hinge assembly 200 of corresponding length.

[0050] Specifically, when the display screen unit 500 is bent from a straight screen to a curved screen, the staff slides the position between two adjacent telescopic parts relatively, thereby shortening the length of the limit assembly 300, and then reducing the distance between the two side frames 100. In this way, the limit assembly 300 effectively controls the distance between the two ends of the hinge assembly 200 through the hinge assembly 200, more precisely, effectively controls the distance between the two sides of the display screen unit 500, so that the staff can conveniently bend the display screen unit 500 to the required curve through the hinge assembly 200. Moreover, the limit assembly 300 adopts the above-mentioned structural form, and the length adjustment operation of the limit assembly 300 is relatively convenient. Therefore, the curved surface adjustment of the display screen unit 500 is relatively convenient, which effectively ensures the work efficiency of the staff.

[0051] In a possible embodiment, there are three telescopic members, namely, a sleeve body 310 and two telescopic rods 320, wherein one telescopic rod 320 is slidably disposed at one end of the sleeve body 310 and connected to one lateral frame 100, and the other telescopic rod 320 is slidably disposed at the other end of the sleeve body 310 and connected to the other lateral frame 100; at the same time, the sides of both ends of the sleeve body 310 are provided with locking members 311, such as fastening bolts, and the end of the locking member 311 located on the inner side of the sleeve body 310 abuts against the side of the telescopic rod 320, thereby fixing the position of the telescopic rod 320 in the sleeve body 310; of course, the locking member 311 can also adopt other fixing structures, such as latches, etc. The sliding arrangement of the telescopic rod 320 and the sleeve body 310 can be direct relative sliding, or the two are connected by threads, and slide and telescope relative to each other during the rotation of the threads.

[0052] In specific applications, when the display screen unit 500 is bent from a straight screen to a curved screen, the staff releases the locking pieces 311 at both ends of the sleeve body 310, and during the bending process of the hinge assembly 200, the two telescopic rods 320 slide inward relative to the sleeve body 310, thereby shortening the distance of the limit assembly 300. When the hinge assembly 200 is bent to a substantially required position, the staff adjusts the relative position between the telescopic rod 320 and the sleeve body 310 according to actual needs, thereby accurately adjusting the bending degree of the hinge assembly 200, thereby allowing the display screen unit 500 to bend and deform synchronously with the hinge assembly 200 to the required arc. After the telescopic adjustment of the limit assembly 300 is completed, the staff tightens the locking piece 311, thereby maintaining the relative position between the sleeve body 310 and the telescopic rod 320, thereby maintaining the display screen unit 500 at the corresponding bending arc.

[0053] In another embodiment, referring to Figure 3 and Figure 8 There are three telescopic parts, namely a sleeve body 310 and two telescopic rods 320, wherein one telescopic rod 320 is slidably arranged at one end of the sleeve body 310 and connected to a lateral frame 100, and the other telescopic rod 320 is slidably arranged at the other end of the sleeve body 310 and connected to the other lateral frame 100; at the same time, the two telescopic rods 320 are circumferentially fixed to the sleeve body 310, for example, the inner wall of the sleeve body 310 is provided with a first positioning surface along its length direction, and the outer walls of the two telescopic rods 320 are provided with a second positioning surface along its length direction, and the first positioning surface is arranged in contact with the second positioning surface, thereby, the two telescopic rods 320 are relatively fixed to the sleeve body 310 in the circumferential direction, that is, the telescopic rods 320 cannot rotate relative to the sleeve body 310. The limiting assembly 300 further includes two annular rotating handles 330 . The two rotating handles 330 are rotatably connected to the two ends of the sleeve body 310 , and the inner sides of the two rotating handles 330 are respectively threadedly connected to the telescopic rod 320 .

[0054] In specific applications, when the display screen unit 500 is bent from a straight screen to a curved screen, the staff controls the hinge assembly 200 to bend while also controlling the rotation of the rotating handle 330. The rotating handle 330 drives the telescopic rod 320 to slide toward the inner side of the sleeve body 310 during rotation, thereby controlling the distance between the two ends of the hinge assembly 200, and then accurately controlling the bending of the hinge assembly 200 to the required curvature. The display screen unit 500 is bent to the required curvature synchronously with the hinge assembly 200.

[0055] In some embodiments, reference Figure 3 , Figure 7 and Fig. 9The display screen support also includes an adjustment mechanism 400, which is used to facilitate the control of the bending of the display screen unit 500. For example, Figure 4 , the adjustment mechanism 400 controls the display screen unit 500 to bend toward its rear side. At this time, the display surface of the display screen unit 500 is switched to an outer curved surface; or, referring to Figure 5 , the joint mechanism 400 controls the display screen unit 500 to bend toward its front side, at this time, the display surface of the display screen unit 500 is switched to an inner curved surface; or, referring to Figure 6 , the adjustment mechanism 400 controls the display screen unit 500 to bend into an S-shape. At this time, the display surface of the display screen unit 500 is switched to an S-shaped curved screen.

[0056] Specifically, the adjustment mechanism 400 includes at least three connection seats and cantilever components 430, wherein there are three connection seats, which are two first connection seats 410 and one second connection seat 420; if there are four or more connection seats, correspondingly, there are two first connection seats 410 and two or more second connection seats 420. For the convenience of description, there are two first connection seats 410 and one second connection seat 420. Specifically, one first connection seat 410 is connected to the top of one lateral frame 100, and one end of the limiting component 300 is connected to the top of the first connection seat 410; another first connection seat 410 is connected to the top of another lateral frame 100, and the other end of the limiting component 300 is connected to the top of the first connection seat 410. The second connection seat 420 is located between the two first connection seats 410 and connected to the back side of a display module 510. The number of cantilever assemblies 430 is one less than the number of connecting seats, and a cantilever assembly 430 is arranged between each adjacent connecting seat, one end of the cantilever assembly 430 is rotatably connected to one connecting seat, and the other end is rotatably connected to another connecting seat. More specifically, a cantilever assembly 430 is arranged between each of the two first connecting seats 410 and the second connecting seat 420, that is, the two ends of the cantilever assembly 430 are rotatably connected to the first connecting seat 410 and the second connecting seat 420, respectively. The cantilever assembly 430 is configured to be able to flexibly adjust itself so as to adapt to the telescopic adjustment of the limit assembly 300.

[0057] Specifically, when bending the display screen unit 500 from a straight screen to a curved screen, the staff roughly adjusts the shape and curvature of the display screen unit 500 by rotating the swing angle of the cantilever assembly 430, so that the display screen unit 500 can be easily adjusted to the required shape and curvature. After the cantilever assembly 430 is adjusted, the staff adjusts the hinge assembly 200 to further correct the shape of the display screen unit 500, thereby bending the display screen unit 500 to the required curved screen. It should be noted here that when the staff adjusts the length of the limit assembly 300, the cantilever assembly 430 automatically adjusts its shape to suit the adjustment of the limit assembly 300.

[0058] It should be noted that during the rotation adjustment process of the cantilever assembly 430, if the limit assembly 300 limits the spacing between the two lateral frames 100, it may interfere with the rotation of the cantilever assembly 430. In the present application, the cantilever assembly 430 can be adjusted by itself, so that it can effectively adapt to the restriction of the restriction assembly 300, and the solution can be implemented.

[0059] In order to make the cantilever assembly 430 adapt to the restriction of the restriction assembly 300, in a possible embodiment, the cantilever assembly 430 includes at least two movable cantilevers 431, and the movable cantilevers 431 are slidably arranged in sequence, so that the cantilever assembly 430 can adjust its own length by telescopic adjustment during the rotation adjustment process, thereby avoiding interference between the cantilever assembly 430 and the limit assembly 300. At the same time, a fastening structure 432 is also arranged between adjacent movable cantilevers 431. After the sliding adjustment of the movable cantilevers 431 is completed, the staff uses the fastening structure 432 to fix the position between the movable cantilevers 431, thereby maintaining the relative position between the movable cantilevers 431; wherein, the fastening structure 432 can adopt a variety of structures, for example, the fastening structure 432 uses the pressing force between the adjacent movable cantilevers 431 for fixing.

[0060] For example, refer to Figure 4 If the cantilever assembly 430 rotates toward the back side of the display unit 500, the movable cantilever 431 shrinks and slides relatively, that is, the cantilever assembly 430 shortens to adapt to the curvature of the display unit 500; or, refer to Figure 5 If the cantilever assembly 430 rotates toward the positive side of the display unit 500, the movable cantilever 431 slides relatively away, and the cantilever assembly 430 stretches to adapt to the curvature of the display unit 500. Figure 6 If one cantilever assembly 430 rotates toward the back side of the display screen unit 500, and the other cantilever assembly 430 rotates toward the front side of the display screen unit 500, therefore, one set of cantilever assemblies 430 is shortened and the other set of cantilever assemblies 430 is extended.

[0061] Specifically, the movable cantilever 431 is provided with two, namely, a first cantilever and a second cantilever (the movable cantilever 431 mentioned above), wherein the first cantilever and the second cantilever are sleeved and slidably arranged, the first cantilever is rotatably connected to the first connecting seat 410, and the second cantilever is rotatably connected to the second connecting seat 420; at the same time, a fastening structure 432 is provided between the first cantilever and the second cantilever for fixing the position between the first cantilever and the second cantilever. The fastening structure 432 can specifically be a tightening handle, a pin, etc.

[0062] In specific applications, the staff releases the restriction of the fastening structure 432, and during the rotation of the cantilever assembly 430, the first cantilever and the second cantilever slide relative to each other, thereby adapting to the restriction of the limit assembly 300. After the rotation adjustment of the cantilever assembly 430 is completed, the staff puts the fastening structure 432 in a locked state, so that the first cantilever and the second cantilever remain in a fixed state, and then the display screen unit 500 remains in the state after the rotation adjustment.

[0063] In order to enable the cantilever assembly 430 to adapt to the restriction of the restriction assembly 300, in another possible embodiment, the cantilever assembly 430 includes at least two movable cantilevers 431. For example, the movable cantilever 431 is provided with at least two movable cantilevers 431, and the movable cantilevers 431 are rotatably arranged in sequence. The movable cantilever 431 located at one end of the cantilever assembly 430 is rotatably connected to the first connecting seat 410, and the movable cantilever 431 located at the other end of the cantilever assembly 430 is rotatably connected to the second connecting seat 420; at the same time, a fastening structure is also provided between adjacent movable cantilevers 431. After the rotation adjustment of the movable cantilever 431 is completed, the staff uses the fastening structure to fix the position between the movable cantilevers 431, thereby maintaining the relative position between the movable cantilevers 431.

[0064] In specific applications, the staff releases the restriction of the fastening structure, and during the rotation of the cantilever assembly 430, the movable cantilevers 431 rotate relative to each other, thereby adapting to the restriction of the limit assembly 300. After the rotation adjustment of the cantilever assembly 430 is completed, the staff puts the fastening structure in a locked state, so that the movable cantilevers 431 remain in a fixed state, and then the display screen unit 500 remains in the rotationally adjusted state.

[0065] In some embodiments, reference Figure 7 and Fig. 9, the second connection base 420 is connected to the top of the hinge module 210, and the hinge module 210 is connected to the back of the display module 510, thereby, the second connection base 420 is connected to the back of the display module 510 through the hinge module 210. It can be understood that when the staff adjusts the display screen unit 500 from a straight screen to a curved surface through the adjustment mechanism 400, the adjustment mechanism 400 adjusts the bending of the display screen unit 500 by adjusting the bending of the hinge assembly 200, thereby, the bending of the display screen unit 500 is effectively controlled, and the display screen unit 500 is not easily damaged.

[0066] Furthermore, the two first connection bases 410 are provided with hanging ears 411, and of course, the second connection base 420 may also be provided with hanging ears 411. In specific applications, the display screen box can be hung on the wall behind it or on the mounting bracket using the hanging ears 411 on the first connection base 410; at the same time, the two side frames 100 are equivalent to the vertical frame of the display screen box, and the hinge assembly 200 is equivalent to the horizontal frame of the display screen box. It can be seen that the first connection base 410 can stably carry the display screen unit 500 through the hinge assembly 200 and the side frames 100, thereby ensuring the stability of the display screen unit 500 in application.

[0067] In some embodiments, reference Figure 2 and Figure 3 At least two groups of hinge assemblies 200 are provided, wherein one group of hinge assemblies 200 is connected between the lower ends of the two side frames 100 to be used as the lower frame of the display screen unit 500; the other group of hinge assemblies 200 is connected between the upper ends of the two side frames 100 to be used as the upper frame of the display screen unit 500. The two groups of hinge assemblies 200 are configured to be able to be spliced ​​together so that the two display screen units 500 can be spliced ​​together. For example, each hinge module 210 of a group of hinge assemblies 200 is provided with a first locking structure 220 (refer to Fig.10 ), the hinge module 210 of the other set of hinge assemblies 200 is correspondingly provided with a first matching portion, and the first locking structure 220 and the first matching portion can be snap-connected, thereby realizing the upper and lower assembly of the two display screen boxes. Of course, if there are three sets of hinge assemblies 200, the third set of hinge assemblies 200 can be provided between the above two sets of hinge assemblies 200, and there is no need to provide the above first locking structure 220 or the first matching portion.

[0068] In specific applications, the side frame 100, the hinge assembly 200 and the display screen unit 500 can be assembled into a display screen box. If multiple display screen boxes are used in combination, the hinge modules 210 of the hinge assembly 200 at the upper end of the display screen box are spliced ​​and connected with the hinge modules 210 of the hinge assembly 200 at the lower end of another display screen box. In this way, multiple display screen boxes can be spliced ​​and connected in sequence, and the limit assembly 300 and the adjustment mechanism 400 only need to be arranged on the display screen box located at the top.

[0069] Furthermore, the two lateral frames 100 are configured to be able to be spliced ​​together so that the two display screen units 500 can be spliced ​​in sequence. For example, one lateral frame 100 is provided with a second locking structure 110, and the other lateral frame 100 is provided with a second matching portion. The second locking structure 110 and the second matching portion can be snap-connected, thereby realizing left-right splicing between the display screen boxes.

[0070] In specific applications, each display box includes two side frames 100. If multiple display boxes are used in combination, the multiple display boxes can be assembled from right to left in sequence, and the second locking structure 110 of the previous box seat is snap-connected with the second matching part of the next display box, so that the display boxes can be assembled from left to right in sequence. If there are enough spliced ​​display boxes, the multiple display boxes can be bent into a cylindrical display screen.

[0071] In some embodiments, reference Fig. 9 and Fig.10 , one of the adjacent hinge modules 210 is provided with an arc-shaped arc groove 2121, and the arc groove 2121 forms a guide opening at the side of the hinge module 210 close to the other hinge module 210; at the same time, the other hinge module 210 is provided with an arc-shaped arc arm 2111 on the side close to the previous hinge module 210, and the arc arm 2111 extends into the arc groove 2121 through the guide opening and slides along the arc groove 2121. Among them, the end of the arc arm 2111 is provided with a first limiting protrusion 2112, and the side wall of the arc groove 2121 close to the guide opening is provided with a second limiting protrusion 2122, and the second limiting protrusion 2122 is used to limit the first limiting protrusion 2112 from sliding off the arc groove 2121, thereby ensuring that the hinge modules 210 always rotate relatively within the set range and remain not separated from each other.

[0072] The hinge module 210 includes a first hinge module 211 and a second hinge module 212. The first hinge module 211 is provided with arc-shaped arms 2111 on opposite sides, and the second hinge module 212 is provided with arc-shaped grooves 2121 on opposite sides. The arc-shaped arms 2111 are slidably arranged in the arc-shaped grooves 2121. Thus, the first hinge module 211 and the second hinge module 212 are alternately arranged in sequence to form a set of hinge components 200. The number of the first hinge modules 211 is one more or one less than the number of the second hinge modules 212. If the number of the first hinge modules 211 is one more than the number of the second hinge modules 212, both ends of the hinge assembly 200 are the first hinge modules 211, that is, both ends of the hinge assembly 200 are arc-shaped arms 2111, and both side frames 100 are provided with arc-shaped grooves 2121 to be assembled with the arc-shaped arms 2111 of the first hinge module 211; if the number of the first hinge module 211 is one less than the number of the second hinge modules 212, both ends of the hinge assembly 200 are the second hinge modules 212, that is, both ends of the hinge assembly 200 are arc-shaped grooves 2121, and both side frames 100 are provided with arc-shaped arms 2111 to be assembled with the arc-shaped grooves 2121 of the second hinge module 212. It can be understood that the hinge assembly 200 adopts the above-mentioned structural form, and the structures at both ends of the hinge assembly 200 are consistent, that is, both ends of the hinge assembly 200 are arc-shaped arms 2111 or arc-shaped grooves 2121, so that the structures of the two side frames 100 can be set consistent, thereby reducing the manufacturing cost of the side frames 100.

[0073] It is understandable that during the relative rotation of the hinge modules 210 and the hinge modules 210, the arcuate arms 2111 slide relatively in the arcuate grooves 2121, thereby realizing the relative rotation between the hinge modules 210 and the hinge modules 210. Thus, each adjacent hinge module 210 rotates relatively, thereby realizing the bending deformation of the display screen unit 500. When the hinge assembly 200 is in a straight line state, the second limiting protrusion 2122 is approximately located at the center of the arcuate arms 2111. If the arcuate arms 2111 slide outward of the arcuate grooves 2121, the hinge assembly 200 bends forward accordingly, and the display screen unit 500 carries the hinge assembly 200 to bend forward, that is, the front of the display screen unit 500 is an inner arc surface (refer to Figure 4 ); if the arc-shaped arm 2111 slides toward the arc-shaped groove 2121, accordingly, the hinge assembly 200 bends backward, and the display unit 500 bends backward along with the hinge assembly 200, that is, the back of the display unit 500 is an inner arc surface (refer to Figure 5); if the hinge module 210 of one section of the hinge assembly 200 rotates backward, that is, the arc-shaped arm 2111 of the hinge module 210 of this section rotates toward the inner side of the arc-shaped groove 2121, and the hinge module 210 of another section of the hinge assembly 200 rotates forward, that is, the arc-shaped arm 2111 of the hinge module 210 of this section rotates toward the outer side of the arc-shaped groove 2121, thereby, the hinge assembly 200 is bent into an S shape (refer to Figure 6 ).

[0074] It can be understood that the arc arm 2111 and the arc groove 2121 are mutually restricted by the first limiting protrusion 2112 and the second limiting protrusion 2122, so that the hinge module 210 can rotate within a set range; moreover, with such a configuration, the arc arm 2111 has a larger range of motion in the arc groove 2121, so that the two hinge modules 210 can be adjusted to any angle within the range of 45 degrees for the inner arc and 45 degrees for the outer arc, thereby enabling the display screen unit 500 to be bent into a sufficiently large arc so as to be suitable for various application scenarios, and in particular, can be bent into a circular display screen with a sufficiently small diameter, thereby having strong market competitiveness.

[0075] The present application also discloses a display screen box, comprising the above-mentioned display screen bracket and a display screen unit 500 , wherein the display screen unit 500 comprises a plurality of display modules 510 , and each display module 510 is sequentially arranged on a hinge module 210 .

[0076] It can be understood that the display box adopts the above-mentioned display bracket, and the staff controls the angle between the hinge modules 210 and the hinge modules 210, so that the hinge assembly 200 is transformed from a straight line arrangement to an arc curve arrangement. Accordingly, the display box is deformed synchronously with the hinge assembly 200, that is, the display box is bent from a straight screen to an arc curved screen (refer to Figure 4 and Figure 5 ); or, the hinge assembly 200 is converted from a linear arrangement to an S-shaped arrangement, and accordingly, the display screen housing is deformed synchronously with the hinge assembly 200, that is, the display screen housing is bent from a straight screen to an S-shaped curved screen (refer to Figure 6 ), of course, the display cabinet may also be bent into other shapes.

[0077] In the process of rotating and adjusting the hinge assembly 200, the staff telescopically adjusts the length of the limit assembly 300, thereby adjusting the spacing between the two lateral frames 100. Accordingly, the spacing between the two ends of the hinge assembly 200 is effectively controlled, and therefore, the curvature of the display screen box is effectively controlled. Specifically, if the staff reduces the length of the limit assembly 300, the curvature of the hinge assembly 200 is effectively increased, and accordingly, the curvature of the display screen box is effectively increased; if the staff increases the length of the limit assembly 300, the curvature of the hinge assembly 200 is effectively reduced, and the curvature of the display screen box is effectively reduced. It can be seen from the above that the curvature of the display screen box is effectively controlled by adjusting the length of the limit assembly 300. Therefore, the hinge assembly 200 cooperates with the limit assembly 300, and the staff can conveniently bend the display screen box into the required curvature.

[0078] The technical means disclosed in the scheme of the present invention are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical schemes composed of any combination of the above-mentioned technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also regarded as the protection scope of the present invention.
