Description

Technical Field

[0001] The present invention relates to the technical field of photodiodes, and specifically to a semiconductor photodiode. Background Art

[0002] A semiconductor photodiode is a component used to convert optical signals into electrical signals. In the prior art, as shown in the technical document with the patent number: CN205542812U and the patent name: A Photodiode, a form of a photodiode component is presented. Such a photodiode generally consists of a detection body part responsible for detecting and converting signals and a pin part used to connect the detection body to an external circuit. For such a photodiode, when manually soldering it to a circuit board, the worker needs to first pass the pins through the mounting holes reserved on the circuit board before performing the soldering operation. However, for reasons such as preventing molten solder from leaking out of the mounting holes, the size of the mounting holes reserved on the circuit board is usually small. Therefore, when the worker passes the pins through the mounting holes, they often need to carefully align the pins with the mounting holes, thus consuming additional operation time and affecting the soldering and installation efficiency of the photodiode.

[0003] Therefore, a semiconductor photodiode is proposed. Summary of the Invention

[0004] The purpose of the present invention is to provide a semiconductor photodiode to improve the soldering and installation efficiency of the photodiode under manual soldering conditions.

[0005] To achieve the above purpose, the present invention provides the following technical solution:

[0006] A semiconductor photodiode includes a detection body, and pins for connecting to an external circuit are provided on the detection body. A pulling device is provided on the pins, and a stabilizing device is provided on the pins.

[0007] Based on this basic solution, during the manual soldering operation of the semiconductor photodiode, the diode can be directly placed at the position of the corresponding mounting hole on the circuit board. Without the need to precisely align the pins with the mounting holes, the pulling device is used to pull the pins to a position precisely aligned with the mounting hole, and then the pins are pulled and inserted into the mounting hole. Thus, the pins can be accurately installed into the mounting hole without the need for the operator to carefully align the position, reducing the operation time required by the operator to align the pins with the mounting hole, thereby improving the soldering and installation efficiency of the photodiode.

[0008] During the process of the pulling device pulling the pin to the position of the mounting hole, the stabilizing device can stably maintain the vertical posture of the pin, so that the pin can directly pass through the mounting hole in a vertical posture during the process of being inserted into the mounting hole, without rubbing against the side surface of the mounting hole, thereby reducing the resistance during the operation of the present invention and improving the movement stability of the present invention. At the same time, this can also avoid the situation where the pin or the circuit board is damaged caused by the pin being inclined when mating with the mounting hole.

[0009] Preferably, the pulling device includes a plurality of pulling hairs fixedly installed at the end of the pin. An installation box is movably installed at the end of the pin where the pulling hairs are installed. The installation box includes an installation part and a docking part. The installation part and the docking part are rotatably connected. A shunt rod is fixedly installed on the docking part. Each of the pulling hairs is evenly arranged in the gap between the shunt rods. A docking groove is formed on the installation part, and a clamping block is fixedly installed on the docking part. The clamping block is in interference fit with the docking groove.

[0010] By setting the pulling device, during the installation of the photodiode, when performing the manual soldering operation of the semiconductor photodiode, the installation box can be directly placed at the position of the corresponding mounting hole on the circuit board. At this time, there is no need to accurately align the positions of the pin and the mounting hole, and it only needs to make the installation box completely cover the two mounting holes. At this time, the pulling hairs aligned with the mounting holes will pass through the mounting holes and extend out from the other side of the circuit board. Then, the operator can directly use his fingers to pinch the pulling hairs extending out from the two mounting holes at the same time and pull. At this time, under the pulling force of the pulling hairs, the pin will be pulled to the position aligned with the mounting hole, then pass through the gap between the shunt rods and finally be inserted into the mounting hole. Thus, the pin can be accurately installed into the mounting hole without the operator carefully aligning the position, so the operation time required by the operator to align the pin with the mounting hole is reduced, and the soldering and installation efficiency of the photodiode is improved.

[0011] The following points are worth noting: First, under the action of the shunt rod, the multiple pulling hairs provided on the pins are separated one by one, and then extend from the bottom end of the mounting box. Thus, the limited number of pulling hairs on a single pin can be separated to cover a wider detection area, which is beneficial to reducing the placement accuracy requirements of the mounting box, and thus more beneficial to reducing the operation time required by the operator to align the pins with the mounting holes, improving the soldering and mounting efficiency of the photodiode; Second, when any pulling hair pulls the pin, the pulling hair must abut against the corresponding shunt rod. Therefore, the pulling force on the pulling hair exerts a lateral component force on the shunt rod. Thus, when the gap between the shunt rods is not aligned with the mounting hole, the lateral force exerted by the pulling hair on the shunt rod will drive the mounting box to shift in position, so that the gap between the shunt rods will finally be aligned with the mounting hole, without affecting the normal use of the present invention; Third, the interference fit between the clamping block and the docking groove enables the mounting part and the docking part to be simply and conveniently fixed to each other by friction, and at the same time can also reduce the difficulty of later removal.

[0012] Preferably, the stabilizing device includes two sliding grooves opened on the mounting part and the docking part. A stabilizing block is movably installed in the two sliding grooves together. Two square placing grooves are symmetrically opened on the stabilizing block, and the placing grooves are used for placing the pins; A plurality of V-shaped grooves are symmetrically opened on the stabilizing block, and the V-shaped grooves are used for accommodating the side surfaces of the sliding grooves.

[0013] By providing the stabilizing device, after the pin is placed in the placing groove in a vertical posture, the side surface of the placing groove will abut against the corresponding pin, so that the pin cannot rotate. Thus, during the process of the pulling hair pulling the pin to the position of the mounting hole, the pin will maintain a vertical posture, so that the pin can directly pass through the mounting hole in a vertical posture during the insertion process without rubbing against the side surface of the mounting hole, thereby reducing the resistance during the operation of the present invention and improving the movement stability of the present invention. At the same time, this can also avoid the situation where the pin or the circuit board is damaged when the pin is inclined to cooperate with the mounting hole, improving the reliability of the present invention.

[0014] In addition, by providing the V-shaped grooves, the side surfaces of the sliding grooves can be placed in the V-shaped grooves, so that the stabilizing block can be slidably installed on the mounting box due to the cooperation between the V-shaped grooves and the side surfaces of the sliding grooves. And because of the V-shaped setting of the V-shaped grooves, the friction form between the V-shaped grooves and the side surfaces of the sliding grooves is line friction at this time, so the friction force between the two is small, which is beneficial to the smooth sliding of the stabilizing block.

[0015] Preferably, the stabilizing block includes a first stabilizing portion and a second stabilizing portion, and V-shaped grooves are provided on both the first stabilizing portion and the second stabilizing portion; the first stabilizing portion is arranged in the sliding groove on the mounting portion, and the second stabilizing portion is arranged in the sliding groove on the docking portion; a recessed portion is provided on the first stabilizing portion, the placement groove communicates with the recessed portion, and a protruding portion is provided on the second stabilizing portion.

[0016] With this arrangement, in the present invention, when installing the pin into the placement groove, the mounting portion and the docking portion can be separated first. At this time, the first stabilizing portion and the second stabilizing portion will also be separated. At this time, there is no need to directly align the pin with the placement groove for placement. Instead, the pin can be roughly placed in the recessed portion. Subsequently, the mounting portion and the docking portion are closed. Then, the protruding portion will squeeze the pin in the recessed portion, causing the pin to slide along the side wall surface of the recessed portion and slide to the placement groove located at the bottom of the recessed portion. After that, under the push of the protruding portion, the pin can finally enter the placement groove. Therefore, during the assembly of the present invention, it is possible to accurately install the pin into the placement groove without precisely aligning the pin with the placement groove, thus reducing the operation time for aligning the pin with the placement groove during the assembly process of the present invention and optimizing the manufacturability of the present invention. At the same time, in the case where the mounting box part of the present invention needs to be reused, this design is also beneficial to improving production efficiency.

[0017] Preferably, a paving plate is fixedly installed on the docking portion, and the paving plate is arc-shaped; when the docking portion and the mounting portion are separated, the arc-shaped paving plate protrudes towards the mounting portion.

[0018] With this arrangement, during the assembly of the present invention, when closing the docking portion and the mounting portion, the paving plate can first press the multiple pulling hairs gathered on the pin against the side wall surface of the mounting portion, and under the extrusion force of the paving plate, force the multiple gathered pulling hairs to disperse and spread on the side of the mounting portion. Then, continue to close the docking portion and the mounting portion. At this time, the multiple pulling hairs can no longer be squeezed and spread. The paving plate will deform towards the inside of the docking portion under the action of the continuously increasing reaction force. Then, the end of the shunt rod will protrude more relative to the paving plate. At this time, each shunt rod can be inserted into the gap between the respective pulling hairs that have been spread out, so that the multiple pulling hairs can be accurately and evenly placed into the gaps between the corresponding shunt rods. Thus, the limited number of pulling hairs on a single pin can be separated as much as possible to cover a wider detection area, which is beneficial to reducing the placement accuracy requirements of the mounting box, and thus more beneficial to reducing the operation time required by the operator to align the pin with the mounting hole and improving the welding and installation efficiency of the photodiode.

[0019] It should be noted that when the paving plate deforms inwardly towards the docking part under the action of the reaction force, since the paving plate is in an arc shape, due to its structural mechanics characteristics, the paving plate will tend to deform into an arc shape symmetrical to the original shape after deformation. Therefore, after the paving plate deforms inwardly towards the docking part, there will be sufficient spacing between the paving plate and the side wall surface of the installation part to ensure that the pins can pass through smoothly, thereby improving the reliability of the present invention.

[0020] In addition, since the paving plate is in an arc shape, that is, an arch shape, when stressed, the paving plate has strong structural compressive resistance and is difficult to bend and deform. Therefore, a plurality of weakening grooves can be evenly opened on the paving plate. These weakening grooves are all opened along the width direction of the paving plate, and all the weakening grooves are opened on the side wall surface of the paving plate close to the docking part. Thus, the mechanical properties of the paving plate can be reduced, so that the paving plate can be more easily bent, improving the movement stability of the present invention.

[0021] Preferably, a pry plate part is fixedly installed at the bottom of the detection body, and a first flat chamfer and a second flat chamfer are respectively opened on the installation part and the docking part, and the pry plate part is used to squeeze the first flat chamfer and the second flat chamfer.

[0022] By setting the pry plate part, when pulling the pin by pulling the hair, after the pin moves a certain distance in the installation hole, the pry plate part at the lower end of the detection body will come into contact with the first flat chamfer and the second flat chamfer. Subsequently, the pin can be continuously pulled, so that the pry plate part simultaneously squeezes the first flat chamfer and the second flat chamfer. At this time, this extrusion will cause the installation part and the docking part to both receive horizontal forces, thereby overcoming the friction between the clamping block and the docking groove, so that the installation part and the docking part are separated, and then the installation box part can be removed from the gap between the photodiode and the circuit board, avoiding the installation box occupying the space of the circuit board and also avoiding the installation box blocking the marked information on the circuit board, thereby avoiding a negative impact on the maintenance of the circuit board of the present invention.

[0023] Preferably, the pry plate part includes a left pry plate and a right pry plate. The lower ends of the left pry plate and the right pry plate are on the same straight line, and the left pry plate and the right pry plate are arranged alternately; the left pry plate is used to squeeze the first flat chamfer, and the right pry plate is used to squeeze the second flat chamfer.

[0024] With this setting, the left pry plate and the right pry plate can specifically extrude the first flat chamfer and the second flat chamfer respectively. Thus, when the left pry plate and the right pry plate respectively retain the sides for cooperating with the first flat chamfer and the second flat chamfer, they can obtain smaller apex angles at the bottom end. As a result, after the pry plate part separates the installation part and the docking part through extrusion, it can more easily insert into the gap between the installation part and the docking part, thereby ensuring the subsequent separation of the installation part and the docking part and ensuring that the installation part and the docking part can be completely separated. Thus, the installation box can be more conveniently taken out from the gap between the detection body and the circuit board.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] 1. By setting the pulling device, during the installation of the photodiode, when performing the manual soldering operation of the semiconductor photodiode, only need to completely cover the two installation holes with the installation box, without precisely aligning the positions of the pins and the installation holes. Then, by pulling the pulling hairs, the pins can be pulled and installed into the installation holes on the circuit board. Thus, even without carefully aligning the positions, the operator can accurately install the pins into the installation holes, reducing the operation time required by the operator to align the pins with the installation holes and improving the soldering and installation efficiency of the photodiode.

[0027] 2. By setting the stabilizing device, during the process of the pulling hairs pulling the pins to the positions of the installation holes, the pins will maintain a vertical posture, so that the pins can directly pass through the installation holes in a vertical posture without rubbing against the side surfaces of the installation holes when inserted into the installation holes, thereby reducing the resistance during the operation of the present invention and improving the motion stability of the present invention. At the same time, this can also avoid the situation of damage to the pins or the circuit board caused by the pins being inclined when cooperating with the installation holes, improving the reliability of the present invention.

[0028] 3. By setting the paving plate, during the assembly of the present invention, the extrusion force of the paving plate can be used to force the gathered multiple pulling hairs to disperse and spread on the side surface of the installation part. At this time, each shunt rod can be inserted into the gaps between the already spread pulling hairs respectively. Thus, the limited number of pulling hairs on a single pin can be separated as much as possible to cover a wider detection area, which is beneficial to reducing the placement accuracy requirements of the installation box and is more beneficial to reducing the operation time required by the operator to align the pins with the installation holes and improving the soldering and installation efficiency of the photodiode.

[0040] The following content will clearly illustrate the specific implementation manners of the present invention with the aid of the drawings listed in the foregoing "Brief Description of the Drawings", so as to enable the reader to more completely and objectively understand the working principle and corresponding technical effects of the present invention.

[0041] Such as Figures 1 to 10As shown, a specific implementation of the present invention is presented. Among them, several points need to be explained in advance: First, the installation and connection method of the detection body 1 and the pin 2 is a mature technology existing in the prior art and will not be elaborated in the following text; Second, after the pin 2 is welded, the pulling hairs 21 on the pin 2 can be removed by cutting off the excess pin 2, so there will be no residue on the circuit board; Third, the pulling hairs 21 are soft, so after the pin 2 passes through the mounting hole, the remaining pulling hairs 21 that are not aligned with the mounting hole can also pass through the mounting hole along with the pin 2 by bending and deforming; Fourth, the first stabilizing part 42 and the second stabilizing part 41 are in an aligned and mating state after the initial installation. Therefore, even if they are separated later, their relative positions on the sliding groove 33 of the mounting box 3 remain roughly unchanged. Therefore, when the mounting box 3 is reused and needs to be combined again, they can be combined without manual alignment adjustment. In addition, even if the first stabilizing part 42 and the second stabilizing part 41 have a certain position offset, due to the cooperation of the protruding part 24 and the concave part 23, the relative positions of the first stabilizing part 42 and the second stabilizing part 41 can still be automatically corrected without manual adjustment; Fifth, the mounting box 3 of the present invention can be reused. When reused, only need to manually restore the paving plate 36 from Figure 8 the state shown to Figure 7 the state shown.

[0042] When the present invention is installed, for the detection body 1 already equipped with the pin 2, a pulling device is provided on the pin 2, and a stabilizing device is provided on the pin 2.

[0043] Among them, the pulling device includes multiple pulling hairs 21 fixedly installed at the end of the pin 2. An end of the pin 2 where the pulling hairs 21 are installed is movably installed with a mounting box 3. The mounting box 3 includes a mounting part 31 and a docking part 32. The mounting part 31 and the docking part 32 are rotationally connected. A flow dividing rod 37 is fixedly installed on the docking part 32. Each pulling hair 21 is evenly arranged in the gap between each flow dividing rod 37; A docking groove 35 is opened on the mounting part 31, and a clamping block 34 is fixedly installed on the docking part 32. The clamping block 34 is in interference fit with the docking groove 35.

[0044] The stabilizing device includes two sliding grooves 33 opened on the mounting part 31 and the docking part 32. A stabilizing block 4 is movably installed in the two sliding grooves 33 together. Two square placing grooves 22 are symmetrically opened on the stabilizing block 4. The placing grooves 22 are used for placing the pin 2; Multiple V-shaped grooves 43 are symmetrically opened on the stabilizing block 4. The V-shaped grooves 43 are used for accommodating the side surfaces of the sliding grooves 33.

[0045] It should be noted that the stabilizing block 4 includes a first stabilizing portion 42 and a second stabilizing portion 41, and V-shaped grooves 43 are provided on both the first stabilizing portion 42 and the second stabilizing portion 41; the first stabilizing portion 42 is arranged in the sliding groove 33 on the mounting portion 31, and the second stabilizing portion 41 is arranged in the sliding groove 33 on the docking portion 32; a recessed portion 23 is provided on the first stabilizing portion 42, the placement groove 22 communicates with the recessed portion 23, and a protruding portion 24 is provided on the second stabilizing portion 41.

[0046] In addition, a paving plate 36 is fixedly installed on the docking portion 32. The paving plate 36 is arc-shaped, and when the docking portion 32 and the mounting portion 31 are separated, the arc-shaped paving plate 36 protrudes towards the mounting portion 31. A plurality of weakening grooves 361 are evenly formed in the paving plate 36, and all the weakening grooves 361 are formed on the side wall surface of the paving plate 36 close to the docking portion 32; all the weakening grooves 361 are formed along the width direction of the paving plate 36. A crowbar portion 5 is fixedly installed at the bottom of the detection body 1, and a first flat chamfer 53 and a second flat chamfer 54 are respectively formed on the mounting portion 31 and the docking portion 32. The crowbar portion 5 is used for squeezing the first flat chamfer 53 and the second flat chamfer 54. The crowbar portion 5 includes a left crowbar 51 and a right crowbar 52. The lower ends of the left crowbar 51 and the right crowbar 52 are located on the same straight line, and the left crowbar 51 and the right crowbar 52 are arranged in an alternating manner; the left crowbar 51 is used for squeezing the first flat chamfer 53, and the right crowbar 52 is used for squeezing the second flat chamfer 54.

[0047] When the present invention works, during the manual soldering operation of the semiconductor photodiode, the diode can be directly placed at the position of the corresponding mounting hole on the circuit board. Without the need to precisely align the pin 2 with the mounting hole, the pin 2 is pulled to a position precisely aligned with the mounting hole by the pulling device, and then the pin 2 is pulled and inserted into the mounting hole. Thus, the pin 2 can be accurately installed into the mounting hole without the need for the operator to carefully align the position, reducing the operation time required by the operator to align the pin 2 with the mounting hole, thereby improving the soldering and installation efficiency of the photodiode.

[0048] During the process of the pulling device pulling the pin 2 to the position of the mounting hole, the stabilizing device can stably maintain the vertical posture of the pin 2, so that the pin 2 can directly pass through the mounting hole in a vertical posture during the insertion process without rubbing against the side surface of the mounting hole, thereby reducing the resistance during the operation of the present invention and improving the movement stability of the present invention. At the same time, this can also avoid the situation where the pin 2 or the circuit board is damaged due to the inclined cooperation of the pin 2 with the mounting hole.

[0049] Specifically, the specific working mode of the pulling device is as follows. During the installation of the photodiode, when performing the manual soldering operation of the semiconductor photodiode, the mounting box 3 can be directly placed at the position of the corresponding mounting hole on the circuit board. At this time, there is no need to precisely align the pins 2 with the mounting holes, but only to ensure that the mounting box 3 can completely cover the two mounting holes. At this time, the pulling hairs 21 aligned with the mounting holes will pass through the mounting holes and protrude from the other side of the circuit board. Then, the operator can directly use his fingers to pinch the pulling hairs 21 protruding from the two mounting holes at the same time and pull. At this time, under the pulling force of the pulling hairs 21, the pins 2 will be pulled to the position aligned with the mounting holes, then pass through the gap between the shunt rods 37 and finally be inserted into the mounting holes. Thus, without the operator carefully aligning the position, the pins 2 can be accurately installed into the mounting holes, reducing the operation time required by the operator to align the pins 2 with the mounting holes and improving the soldering and installation efficiency of the photodiode.

[0050] The following points are worth noting: First, the multiple pulling hairs 21 provided on the pins 2 are separated one by one under the action of the shunt rods 37 and then protrude from the bottom end of the mounting box 3. This allows the limited number of pulling hairs 21 on a single pin 2 to be separated to cover a wider detection area, which is beneficial to reducing the placement accuracy requirements of the mounting box 3, and thus more conducive to reducing the operation time required by the operator to align the pins 2 with the mounting holes and improving the soldering and installation efficiency of the photodiode. Second, when any one of the pulling hairs 21 pulls the pin 2, this pulling hair 21 will necessarily abut against the corresponding shunt rod 37. Then, the pulling force on the pulling hair 21 exerts a lateral component force on the shunt rod 37. Therefore, when the gap between the shunt rods 37 is not aligned with the mounting hole, the lateral force exerted by the pulling hair 21 on the shunt rod 37 will drive the mounting box 3 to shift in position, so that the gap between the shunt rods 37 will finally be aligned with the mounting hole, without affecting the normal use of the present invention. Third, the interference fit between the clamping blocks 34 and the docking grooves 35 enables the mounting part 31 and the docking part 32 to be simply and conveniently fixed to each other by friction, and at the same time, it can also reduce the difficulty of later removal.

[0051] The specific working mode of the stabilizing device is as follows. After the pin 2 is placed in the placement groove 22 in a vertical posture, the side surface of the placement groove 22 will be in contact and cooperation with the corresponding pin 2, so that the pin 2 cannot rotate. Therefore, during the process of the pulling hair 21 pulling the pin 2 to the position of the mounting hole, the pin 2 will maintain a vertical posture, so that the pin 2 can directly pass through the mounting hole in a vertical posture during the insertion process without rubbing against the side surface of the mounting hole, thereby reducing the resistance during the operation of the present invention and improving the movement stability of the present invention. At the same time, this can also avoid the situation where the pin 2 or the circuit board is damaged when the pin 2 is inclined to cooperate with the mounting hole, and improve the reliability of the present invention.

[0052] In addition, by providing the V-shaped groove 43, the side surface of the sliding groove 33 can be placed in the V-shaped groove 43, so that the stabilizing block 4 can be slidably mounted on the mounting box 3 due to the cooperation between the V-shaped groove 43 and the side surface of the sliding groove 33. And due to the setting of the V-shaped shape of the V-shaped groove 43, the friction form between the V-shaped groove 43 and the side surface of the sliding groove 33 at this time is line friction, so the friction force between the two is small, which is beneficial to the smooth sliding of the stabilizing block 4.

[0053] It should be noted that when the docking part 32 and the mounting part 31 are closed, the paving plate 36 can first press the multiple pulling hairs 21 gathered on the pin 2 against the side wall surface of the mounting part 31, and under the extrusion force of the paving plate 36, force the multiple gathered pulling hairs 21 to disperse and spread on the side surface of the mounting part 31. Then, continue to close the docking part 32 and the mounting part 31. At this time, the multiple pulling hairs 21 can no longer be squeezed and spread. The paving plate 36 will deform towards the inside of the docking part 32 under the action of the continuously increasing reaction force. Therefore, the end of the shunt rod 37 will be more prominent relative to the paving plate 36. At this time, each shunt rod 37 can be inserted into the gaps between the respective pulling hairs 21 that have been spread out, so that the multiple pulling hairs 21 can be accurately and evenly placed in the gaps between the corresponding shunt rods 37. Thus, the limited number of pulling hairs 21 on a single pin 2 can be separated as much as possible to cover a wider detection area, which is beneficial to reducing the placement accuracy requirements of the mounting box 3, and thus more beneficial to reducing the operation time required by the operator to align the pin 2 with the mounting hole and improving the welding and mounting efficiency of the photodiode.

[0054] It should also be supplemented and explained that when the paving plate 36 deforms inwardly towards the docking part 32 under the action of the reaction force, since the paving plate 36 is arc-shaped, due to its structural mechanics characteristics, the paving plate 36 will tend to deform into an arc shape symmetrical to the original shape after deformation. Therefore, after the paving plate 36 deforms inwardly towards the docking part 32, there will be enough space between it and the side wall surface of the installation part 31 to ensure that the pins 2 can pass through smoothly, thereby improving the reliability of the present invention.

[0055] In addition, since the paving plate 36 is arc-shaped, that is, arched, the structural compressive capacity of the paving plate 36 is strong when stressed, and it is difficult to undergo bending deformation. Therefore, a plurality of weakening grooves 361 can be evenly opened on the paving plate 36, and these weakening grooves 361 are all opened along the width direction of the paving plate 36, and all the weakening grooves 361 are opened on the side wall surface of the paving plate 36 close to the docking part 32. Thus, the mechanical properties of the paving plate 36 can be reduced, so that the paving plate 36 can be more easily bent, improving the movement stability of the present invention.

[0056] It should be emphasized that based on the content recorded in the above text, although the beneficial effects of the present invention have been elaborated in detail and corresponding specific implementation manners have been provided, however, those of ordinary skill in the art can still, on the premise of fully understanding the working principle of the present invention, make conventional substitutions, deformations and other modifications that do not require creative labor based on the given technical solutions to achieve the same technical effects, but this should not be considered as exceeding the scope of the present invention. Specifically, the scope of the present invention is defined by the appended claims and their equivalents.
