Lithium battery modules are important components of new energy vehicles, and they need to be installed with Figure 1 The explosion-proof sensor 102 shown. Before the battery module explosion-proof sensor is connected to the battery module, it is necessary to perform a performance test on it, and perform a series of processing such as cutting, bending, and angle forming on its pins. The current common method is to use a separate corresponding equipment to perform multi-station testing, bending, and forming processing on it. It is impossible to achieve multiple continuous operations of battery module sensor performance testing, trimming, bending, and angle forming, and the production efficiency is low, which is difficult to meet the needs of mass production. Summary of the invention

[0003] The technical problem to be solved by the present invention is: in order to improve the production efficiency and quality of battery module explosion-proof sensors and meet the needs of multi-station continuous production, the present invention provides a new energy vehicle battery module explosion-proof sensor detection and pin forming integrated machine.

[0004] The technical solution adopted by the present invention to solve its technical problems is: an all-in-one machine for explosion-proof sensor detection and pin forming of new energy vehicle battery modules, comprising a rotating worktable, a rotating worktable rotation driving device is arranged at the bottom of the rotating worktable, and an explosion-proof sensor pressure resistance automatic testing device, an explosion-proof sensor impedance testing device, an explosion-proof sensor automatic rejection device, an explosion-proof sensor pin trimming device, an explosion-proof sensor pin bending device and an explosion-proof sensor pin angle shaping device are arranged around the outer periphery of the rotating worktable in sequence from front to back of the process.

The two protruding ends of the pressure test bidirectional cylinder are respectively installed with a pressure test upper clamp block and a pressure test lower clamp block. The two protruding ends of the pressure test bidirectional cylinder can drive the pressure test upper clamp block and the pressure test lower clamp block to clamp and loosen. A pressure conductive sheet is also fixedly installed on the pressure test upper clamp block.

[0068] like Figure 7-9As shown, the explosion-proof sensor impedance testing device 300 and the explosion-proof sensor automatic rejection device 400 are connected through a controller signal. After the explosion-proof sensor is tested by the explosion-proof sensor impedance testing device 300, the test signal is transmitted to the controller.

[0073] The explosion-proof sensor impedance testing device 300 is located at the periphery of the rotating workbench 1, and the pin mounting slot 1022 faces the periphery of the rotating workbench 1. The rear end of the explosion-proof sensor pin 1023 is inserted into the pin mounting slot 1022 at the front end of the explosion-proof sensor 102. The height of the pin support 1071 is set just enough to make the middle part of the explosion-proof sensor pin 1023 embedded in the pin slot 1072, and the explosion-proof sensor pin 1023 does not deform. The pin support 1071 only supports the pin. The rotation of the rotating workbench 2 can make the front end of the explosion-proof sensor pin 1023 rotate to the impedance test clamp. The impedance test bidirectional cylinder 304 is in the extended state, and there is a certain distance between the impedance test upper clamp 305 and the impedance test lower clamp 306. The impedance test bidirectional cylinder 304 works, so that the impedance test upper clamp 305 and the impedance test lower clamp 306 move toward each other, and the pin spacing block 3061 is inserted between the two explosion-proof sensor pins 1023. At the same time, the pin spacing frame 3062 moves upward with the impedance test lower clamp 306. The pin spacing plate 3063 on the surface of the pin spacing frame 3062 is inserted between the two explosion-proof sensor pins 1023, and the explosion-proof sensor pins 1023 are separated by a certain distance to ensure that the two explosion-proof sensor pins 1023 do not contact each other. The surface of the pin spacing frame 3062 is not higher than the surface of the impedance test lower clamp 306. After the impedance test bidirectional cylinder 304 is closed, the impedance test upper clamp 305 and the impedance test lower clamp 306 are closed, and the front ends of the two explosion-proof sensor pins 1023 are respectively pressed against the two impedance test metal sheets 307. At this time, the ends of the two impedance test metal sheets 307 on the impedance test upper clamp 305 are respectively connected to cables, and the other ends of the cables are connected to the positive and negative terminals of the impedance tester to form a loop. The impedance tester installed at the staff station starts the test work, that is, the working current is passed through the cable to the explosion-proof sensor 102, and then the impedance value between the two explosion-proof sensor pins 1023 is detected, and the sensor impedance performance is judged to be qualified according to the test results, and finally the next process is transferred.

[0074] When the impedance tester detects that the impedance value of the explosion-proof sensor pin 1023 is unqualified, a signal is sent to the controller, and the controller sends a signal to the explosion-proof sensor automatic rejection device, and the explosion-proof sensor automatic rejection device starts to work, the rotary worktable 1 rotates, so that the workpiece fixing seat 100 is located below the other end of the swing arm 403, and the rejection lifting cylinder 402 descends, so that the swing arm 403 descends as a whole, and the suction cup 404 is pressed to the surface of the explosion-proof sensor 102 on the workpiece fixing seat 100, and the suction device works to draw air into the ventilation pipe 405, so that the suction cup 404 sucks the explosion-proof sensor 102, and the rejection lifting cylinder 402 rises, so that the explosion-proof sensor 102 is lifted (taken out), and the rejection swing cylinder 401 rotates, driving the rejection lifting cylinder 402 and the swing arm 40 to swing together, thereby removing the explosion-proof sensor 102 and rejecting the unqualified explosion-proof sensor 102. When the impedance value of the explosion-proof sensor 102 is qualified, the controller does not operate the explosion-proof sensor automatic rejection device.

[0075] like Figure 10-12 As shown, the pin trimming device 500 of the explosion-proof sensor includes a pin trimming device mounting seat 501, a pneumatic scissors 502, a pneumatic scissors mounting bracket 503, a pneumatic scissors bracket connecting block 504, a pneumatic scissors bracket mounting slider 505 and a pneumatic scissors linear guide 506, wherein the pneumatic scissors linear guide 506 is horizontally fixedly arranged on the pin trimming device mounting seat 501, one end of the pneumatic scissors linear guide 506 faces the rotary worktable 1, the pneumatic scissors bracket mounting slider 505 and the pneumatic scissors linear guide 506 are slidably matched, the pneumatic scissors bracket connecting block 504 and the pneumatic scissors bracket mounting slider 505 are fixedly connected, the pneumatic scissors mounting bracket 503 and the pneumatic scissors bracket connecting block 504 are fixedly connected, the pneumatic scissors 502 are mounted on the pneumatic scissors mounting bracket 503, and a pneumatic scissors driving motor 507 is also installed on the pin trimming device mounting seat 501, and the output end of the pneumatic scissors driving motor 507 is fixedly connected with a horizontally arranged driving screw, and a driving nut 508 is sleeved on the driving screw. A pneumatic scissors drive bending piece 509 is fixedly installed at the end of the pneumatic scissors bracket connecting block 504. The pneumatic scissors drive bending piece 509 is L-shaped. One end of the pneumatic scissors drive bending piece 509 is fixedly connected to the pneumatic scissors bracket connecting block 504, and the other end of the pneumatic scissors drive bending piece 509 is fixedly connected to the drive nut 508.

[0076] The pins of the sensor are mounted on the workpiece fixing seat on the rotating worktable 1. The conditions that the scissor openings of the pneumatic scissors 502 are facing are as follows: when the rotating worktable 1 rotates, the pins of the sensor can enter the scissor openings of the pneumatic scissors 502. A pin guide limit plate 510 is fixedly mounted on the side of the pneumatic scissors 502 close to the rotating worktable 1. A pin guide limit opening 5101 is provided at one end of the pin guide limit plate 510 close to the scissor openings of the pneumatic scissors 502 toward the middle of the pin guide limit plate 510. The pin guide limit opening 5101 gradually expands from the inside to the outside. The angle α of the pin guide limit opening 5101 is 10°-15°. The pin guide limit plate 510 can cover the two scissor blades of the pneumatic scissors 502. After the scissor openings of the pneumatic scissors 502 are opened, they partially overlap with the pin guide limit opening 5101.

[0077] A pin collecting bucket 511 is also provided on the cylinder shell of the pneumatic scissors 502. The discharge direction of the pin collecting bucket 511 extends in the direction opposite to the scissor mouth of the pneumatic scissors 502, and the pin collecting bucket 511 is tilted downward by 25°-35°. The pin collecting bucket 511 has a downwardly tilted lower slide plate and an upper baffle plate. The upper ends of the lower slide plate and the upper baffle plate are fixedly connected to the cylinder of the pneumatic scissors 502. The upper baffle plate 5111 can cover the top of the two scissor blades of the pneumatic scissors 502. The plate surface part of the upper baffle plate 5111 extending downward is open, which can prevent the cut pins from flying around, does not affect observation, and is also conducive to the cut pins sliding out along the pin collecting bucket 511. A support frame is provided at the bottom of the lower slide plate 5112.

[0078] When in use, the rotary workbench 1 rotates from the previous process to the stitch trimming process position, the pneumatic scissors drive motor 507 drives the output shaft, the output shaft drives the drive screw to rotate, and the drive nut 508 moves on the drive screw, thereby driving the pneumatic scissors bracket mounting slider 505 to move along the linear pneumatic scissors linear guide 506 rotary workbench 1, driving the pneumatic scissors 502 and the stitch guide limit plate 510 to move together, and the sensor pin 1023 is limited in the stitch guide limit opening 5101 of the stitch guide limit plate 510. When the pneumatic scissors 502 is not working, the scissor mouth 5021 is in an open state, and when the pneumatic scissors 502 is working, the scissor mouth is closed. The sensor pin 1023 is trimmed, and the trimmed pin residue falls into the pin collecting bucket 511. The pneumatic scissors drive motor 507 drives the pneumatic scissors bracket mounting slider 505 to retreat along the linear pneumatic scissors linear guide 506 to the opposite direction of the rotary workbench 1, driving the pneumatic scissors 502 and the pin guide limit plate 510 to retreat together, completing the trimming of the pin, and the rotary workbench 1 rotates, so that the workpiece fixing seat 100 rotates from the current position to the next process.

[0079] like Figure 13-15As shown, the explosion-proof sensor pin bending device 600 includes a bending device mounting seat 601, on which a downward pressing bending mechanism 602, a supporting mechanism 603 and a right-angle pressing and forming mechanism 604 are installed. The downward pressing bending mechanism 602 is located above the workpiece fixing seat 100, and the side of the workpiece fixing seat 100 facing the outer periphery of the rotating worktable 1 is the outer side. The downward pressing bending mechanism 602 can press and bend the explosion-proof sensor pin 1023 exposed to the outer periphery of the rotating worktable 1 to pre-form it, the supporting mechanism 603 is supported below the explosion-proof sensor pin 1023, and the right-angle pressing and forming mechanism 604 is located obliquely above the outer side of the explosion-proof sensor pin 1023, and the right-angle pressing and forming mechanism 604 can press and form the bent corner of the explosion-proof sensor pin 1023.

[0080] The downward pressure bending mechanism 602 includes a downward pressure lifting cylinder 6021, a clamping block 6022 and a downward pressure plate 6023. A longitudinal mounting plate is arranged on the upper part of the bending device mounting seat 601. The downward pressure lifting cylinder 6021 is fixedly arranged on one side of the longitudinal mounting plate toward the center of the rotating worktable. The telescopic end of the downward pressure lifting cylinder 6021 is vertically facing downward. The clamping block 6022 and the telescopic end of the downward pressure lifting cylinder 6021 are fixedly connected. The downward pressure plate 6023 and the outer side surface of the clamping block 6022 are fixedly connected. The bottom surface of the downward pressure plate 6023 is lower than the bottom surface of the clamping block 6022. A right-angle pressure opening 6024 is formed between the bottom surface part of the downward pressure plate 6023 lower than the clamping block 6022 and the bottom surface of the clamping block 6022.

[0081] The supporting mechanism 603 includes a supporting lifting cylinder 6031 and a supporting block 6032. The supporting lifting cylinder 6031 is fixedly arranged on the lower part of the bending device mounting seat 601. The telescopic end of the supporting lifting cylinder 6031 is vertically facing upwards. The supporting block 6032 is fixedly connected to the telescopic end of the lifting cylinder 6031. An auxiliary forming block 6033 is fixedly arranged on the upper surface of the supporting block 6032. The surface of the auxiliary forming block 6033 has a forming protrusion 6034. A right-angle support opening 6035 is formed between the side of the forming protrusion 6034 and the surface of the auxiliary forming block 6033. The right-angle support opening 6035 faces the workpiece fixing seat 100.

[0082] When the downward telescopic cylinder 6045 is not working, the pressure arm 6043 is in a horizontal state, and the right-angle pressure forming mechanism 604 includes an articulated seat 1 6041, an articulated seat 2 6042, a pressure arm 6043 and a downward telescopic cylinder 6045. The articulated seat 1 6041 and the articulated seat 2 6042 are both fixed on the bending device mounting seat 601. The articulated seat 1 6041 is closer to the rotary worktable 1 than the articulated seat 2 6042. The articulated seat 1 6041 is fixedly arranged on the side of the longitudinal mounting plate facing away from the center of the rotary worktable. One end of the pressure arm 6043 is hinged to the articulated seat 1 6041, the cylinder end of the downward telescopic cylinder 6045 is hinged to the articulated seat 2 6042, and the telescopic end of the downward telescopic cylinder 6045 is hinged to the pressure arm 6043. The hinge seat 2 6042 is higher than the hinge seat 1 6041, and the hinge point between the telescopic end of the downward-pressing telescopic cylinder 6045 and the pressing arm 6043 is located on the upper surface of the pressing arm 6043 near the other end of the pressing arm 6043. A wide-mouth groove 6044 is provided on the lower surface of the pressing arm 6043 near the other end, and the width of the wide-mouth groove 6044 is greater than the height of the pressing block 6022 (more specifically, the width of the wide-mouth groove 6044 is greater than the overall height of the pressing block 6022 and the pressing plate 6023 after installation), and the end surface of the other end of the pressing arm 6043 is slightly inclined inward from top to bottom. The inner side wall of the wide-mouth groove 6044 near the other end of the pressing arm 6043 is the outer side wall, and a forming pressure head 6046 is formed between the outer side wall and the end surface of the other end of the pressing arm 6043.

[0083] The upper surface of the sensor pin bracket is provided with a pin support. When the telescopic end of the lifting cylinder is pressed down and extended, the right-angle pressing portion can be pressed just on the corner of the upper surface and the outer side of the pin support. The outer side of the pin support faces the outside of the rotating workbench. The sensor pins are supported on the pin support. The sensor pins exposed on the pin support are pressed down by the right-angle pressing portion, and the horizontal sensor pins are bent downward.

[0084] Working principle of the explosion-proof sensor pin bending device: The upper surface of the sensor pin bracket has a pin support 1071, and the front of the explosion-proof sensor pin 1023 is exposed on the pin support 1071. Figure 2 The explosion-proof sensor pin 1023 is in a horizontal state before bending. The front part of the sensor pin bracket 107 is protruding from the front end of the pin mounting support 106. The rotating table 1 rotates, driving the workpiece fixing seat 100 to rotate to the explosion-proof sensor pin bending and forming station, that is, between the pressing bending mechanism 602 and the supporting mechanism 603.

[0085] First, the telescopic end of the supporting lifting cylinder 6031 of the supporting mechanism 603 is extended first, so that the auxiliary molding block 6033 rises with the supporting block 6032, and the surface of the auxiliary molding block 6033 is against the lower surface of the front part of the sensor pin bracket 107, and the rear end of the molding protrusion 6034 is against the front end of the sensor pin bracket 107, that is, the right-angle support mouth 6035, which is just stuck in the corner below the front end of the sensor pin bracket 107, and the molding protrusion 6034 is located below the front part of the explosion-proof sensor pin 1023, waiting for the explosion-proof sensor pin 1023 to be pressed down and bent.

[0086] Next, the protruding end of the downward pressure lifting cylinder 6021 is extended, causing the vertical clamping block 6022 and the lower pressure plate 6023 to descend, and the bottom surface of the clamping block 6022 is pressed on the pin support 1071 and the workpiece fixing seat 100. The bottom surface of the lower pressure plate 6023 moves downward along the front end surface of the pin support 1071, causing the front part of the sensor pin bracket 107 to bend, forming an L-shaped vertical part along the front end surface of the pin support 1071, and the right-angle pressing port 6024 is just pressed on the corner of the upper end surface and the front end surface of the pin support 1071. The formed protrusion 6034 supported on the lower front part of the explosion-proof sensor pin 1023 in the previous step can make the explosion-proof sensor pin 1023 bend again after being pressed to form the prototype of a horizontal forward lateral part. In order to facilitate the subsequent pressure forming of the pressure arm 6043, the surface of the formed protrusion 6034 is a slightly inclined surface, and the end close to the pin support 1071 is slightly higher.

[0087] Then, the telescopic end of the downward-pressing telescopic cylinder 6045 is extended, so that the other end of the pressing arm 6043 rotates around one end of the pressing arm 6043, and the other end of the pressing arm 6043 moves toward the corner between the vertical part and the horizontal part of the L-shape. After the telescopic end of the downward-pressing telescopic cylinder 6045 is extended into place, the pressing arm 6043 basically changes from a horizontal state to a vertical state. At this time, the forming pressure head 6046 is located between the lower pressure plate 6023 and the forming protrusion 6034, further strengthening the forming effect of the corner of the vertical part and the horizontal part of the front part of the explosion-proof sensor pin 1023, forming Figure 7 The effect shown is achieved, the required pin bending process is completed, and then the next process is transferred. In the horizontal state, the other end face of the pressing arm 6043 is slightly inclined inward from top to bottom, so that when the pressing arm 6043 is in the vertical state, it is easy to enter between the lower pressing plate 6023 and the forming protrusion 6034. The inclination of the other end face of the pressing arm 6043 and the inclination of the upper surface of the forming protrusion 6034 are matched with each other, which further improves the forming effect.

[0088] like Figure 16-20As shown, the explosion-proof sensor pin angle shaping device 700 includes an angle device mounting seat 701, an explosion-proof sensor clamping and fixing device 702 and a pin pushing mechanism 703.

The fixed clamping block 7022 is fixedly connected to the telescopic end of the fixed clamping cylinder 7021. When the telescopic end of the fixed clamping cylinder 7021 is extended, the fixed clamping block 7022 can be pressed on the surface of the explosion-proof sensor.

[0089] The pin spreading mechanism 703 includes a spreading mechanism mounting plate 7031 which is slidable up and down and is arranged on the side wall of the spreading device mounting seat 701. A vertical spreading mechanism linear slide rail 705 is arranged on the side wall of the spreading device mounting seat 701.

The tip of the wedge block 7041 and the tip of the wedge plate 7042 are both in a vertical plane passing through a certain radius of the rotary table 1.

[0091] The wedge block 7041 extends vertically downward from the tip of the top thereof, and divides the wedge block 7041 and the opening block 704 into an opening block 1 7044 and an opening block 2 7043. The opening block 1 7044 and the opening block 2 7043 are connected to the opening mechanism mounting plate 7031 through an angle-expanding four-bar linkage mechanism.

The wedge block 1 is fixedly connected to the opening block 1 7044, and the wedge block 2 is fixedly connected to the opening block 2 7043.

[0092] The four-bar expansion angle linkage mechanism includes an expansion angle link 1 7071, an expansion angle link 2 7072, an expansion angle link 3 7073 and an expansion angle link 4 7074. The upper end of the expansion angle link 1 7071 is hinged to the upper end of the expansion angle link 2 7072, and the hinge axis of the upper end of the expansion angle link 1 7071 and the upper end of the expansion angle link 2 7072 is fixed to the side of the expansion mechanism mounting plate 7031. The lower end of the expansion angle link 1 7071 is hinged to the upper end of the expansion angle link 3 7073, the lower end of the expansion angle link 2 7072 is hinged to the upper end of the expansion angle link 4 7074, and the lower end of the expansion angle link 3 7073 is hinged to the expansion angle link 4 7074. 074 is hinged at the lower end, and the side of the expansion mechanism mounting plate 7031 is located below the angle-expanding four-bar linkage mechanism and is also fixedly connected with an upper and lower driving cylinder 708 of the connecting rod mechanism. The telescopic end of the upper and lower driving cylinder 708 of the connecting rod mechanism is vertically arranged upward, and the telescopic end of the upper and lower driving cylinder 708 of the connecting rod mechanism is hinged with the lower end of the angle-expanding link three 7073 through the support ear 7075, the support ear 7075 and the telescopic end of the upper and lower driving cylinder 708 of the connecting rod mechanism are fixedly connected, the expansion block one 7044 and the lower end of the angle-expanding link one 7071 are fixedly connected, and the expansion block two 7043 and the lower end of the angle-expanding link two 7072 are fixedly connected.

[0093] The outer side surface of the fixed pressing block 7022 (the side of the fixed pressing block 7022 facing the pin pushing mechanism is the outer side surface) is also fixedly connected to a closing limit connecting plate 709, the bottom of the closing limit connecting plate 709 is basically flush with the bottom of the fixed pressing block 7022, and the bottom of the closing connecting plate 709 is close to the outer side of the closing connecting plate 709. Extending downwardly from the closing limit baffle 710, two symmetrical angle limit plates 711 are fixedly arranged side by side on the outer side surface of the closing limit connecting plate 709 to the outer side surface of the closing limit baffle 710, there is a spacing between the two angle limit plates 711, and the spacing gradually increases from top to bottom, the bottom of the two angle limit plates 711 is exposed at the bottom of the closing limit baffle 710, when the telescopic end of the expansion mechanism mounting plate lifting cylinder 7032 extends out, the expansion mechanism mounting plate 7031 rises, and the expansion mechanism mounting plate 7031 drives the expansion block 704 to rise. The wedge block 7041 on the opening block 704 is located between the bottom of the closing connection plate 709 and the inner side of the closing limit baffle 710 .

[0094] The working principle of the single-station angle shaping device for the explosion-proof sensor pins of the battery module is as follows: the upper surface of the sensor pin bracket has a pin support 1071, and the front part of the explosion-proof sensor pin 1023 is exposed on the pin support 1071 and is bent, such as Figure 4 The front part of the sensor pin bracket 107 is protruding from the front end of the pin mounting support 106. The front end surface of the sensor pin bracket 107 is flush with the front end surface of the pin support 1071, and the front end surfaces are both facing the outer periphery of the rotary table 1. The rotary table 1 rotates, driving the workpiece fixing seat 100 to rotate to the explosion-proof sensor pin angle position, that is, between the explosion-proof sensor clamping and fixing device 702 and the pin pushing mechanism 703,

[0095] First, the telescopic end of the fixed clamping cylinder 7021 extends downward, so that the fixed clamping block 7022 is pressed against the surface of the explosion-proof sensor 102 to fix the explosion-proof sensor 102. At this time, the closing limit baffle 710 is located in front of the needle support 1071, and there is a distance between the closing limit baffle 710 and the front end surface of the needle support 1071, which is used for the entry of the wedge block 7041 and the wedge plate 7042.

[0096] Next, the protruding end of the expansion mechanism mounting plate lifting cylinder 7032 on the side wall of the angle device mounting seat 701 extends upward, driving the expansion mechanism mounting plate 7031 to move upward (the expansion mechanism slider 706 slides upward on the expansion mechanism linear slide rail 705, and the sliding mechanism has a guiding and limiting function), so that the components on the expansion mechanism mounting plate 7031 move upward together, including the wedge block 7041. The wedge block 7041 moves upward along the front end surface of the sensor pin bracket 107 and the front end surface of the pin support 1071. The tip of the wedge block 7041 can just enter between the two explosion-proof sensor pins 1023 first. Since the width of the wedge block 7041 gradually widens from top to bottom, the two explosion-proof sensor pins 1023 can be gradually separated to both sides to form an angled state. The bottoms of the two angle limit plates 711 are exposed at the bottom of the closing limit baffle 710, the bottom spacing of the two angle limit plates 711 is greater than the width of the middle of the wedge block 7041, and the transverse portion 10232 of the front of the explosion-proof sensor pin 1023 is lower than the vertical portion 10231 of the explosion-proof sensor pin 1023. Therefore, the bottoms of the two angle limit plates 711 can just clamp the two sides of the transverse portion 10232 of the two explosion-proof sensor pins 1023 to prevent the two explosion-proof sensor pins 1023 from having too large an angle.

[0097] The angle-expanding four-bar linkage mechanism can further adjust the angle of the opening of the two explosion-proof sensor pins 1023. At this time, the wedge block 7041 needs to be designed as a split type, that is, it is divided into an opening block 1 7044 and an opening block 2 7043. When the upper and lower driving cylinders 708 of the connecting rod mechanism are not working, the telescopic ends of the upper and lower driving cylinders 708 of the connecting rod mechanism are in a retracted state. When the telescopic ends of the upper and lower driving cylinders 708 of the connecting rod mechanism are extended upward, the angle-expanding connecting rod 3 7073 The lower end of and the lower end of the angle connecting rod 4 7074 move upward, and the upper end of the angle connecting rod 3 7073 and the upper end of the angle connecting rod 4 7074 open to each other, so that the lower end of the angle connecting rod 1 7071 and the lower end of the angle connecting rod 2 7072 open, thereby making the expansion block 1 7044 and the expansion block 2 7043 open, and the expansion method is that the bottom expansion distance of the expansion block 1 7044 and the expansion block 2 7043 is greater than the upper expansion distance, and the expansion mechanism mounting plate 7031 is also installed on both sides of the expansion mechanism mounting plate 7031. The lower end of the angle connecting rod 1 7071 and the lower end of the angle connecting rod 2 7072 are prevented from opening too much. The state diagram after the angle expansion process is completed is as follows Fig. 20 shown.
