Before use, the yarn wheel is installed on the side wall of the mounting plate, the wire end of the yarn wheel is hung downward, and it is ensured that the wire end of the yarn wheel passes through the gap between the extrusion columns and the clamping groove, presenting a Figure 1 The electric telescopic rod is then powered on, and the electric telescopic rod drives the sliding frame to slide downward along the outer wall of the mounting plate. During the downward movement of the rotating column, the side wall of the incomplete gear will contact the side wall of the rotating rod 1, presenting a Figure 4 At this time, the broken gear drives the driving column and the rotating column to rotate, and the rotating rotating column drives the folded metal curtain to slide along the inner wall of the sliding groove. In this process, the clamping groove drives the line segment of the yarn wheel to move synchronously, so that the folded metal curtain is wrapped around the outer wall of the rotating column, presenting a Figure 7 state, at this time the line end of the yarn wheel is clamped by the rotating column and the folded metal curtain, and the top of the outer wall of the yarn wheel is clamped and restricted by the extrusion column. At this time, the electric telescopic rod continues to shrink. At this time, the yarn wheel will be pulled, and the elastic force detection process is carried out. During the detection process, the compressed position at the bottom of the yarn wheel line end is on the outer wall of the rotating column. Through the application of the above-mentioned components, when the equipment pulls the yarn wheel, the clamped position and the compressed position at the bottom of the yarn wheel are separated, thereby reducing the influence of the external clamping force on the pulling end and improving the detection accuracy of the equipment.

[0011] Preferably, the driving assembly includes a driving rod 1 fixedly connected to the top of the sliding frame, a plurality of right-angle grooves 2 are opened on the side wall of the driving rod 1, a rotating rod 2 is rotatably connected to the inner wall of the plurality of right-angle grooves 2, a mounting frame is fixedly connected to the side wall of the mounting plate, an L-shaped rod is slidably connected to the inner wall of the mounting frame, a spring 2 is fixedly connected to the bottom of the L-shaped rod, and a cleaning assembly is fixedly connected to the bottom of the sliding frame. By utilizing the characteristics of the rotating column and the folded metal curtain clamping the yarn wheel end, when the incomplete gear rotates, since the incomplete gear itself has only half the volume, this will force the incomplete gear to only drive the rotating column to rotate half a circle, and finally present the following Figure 7 The broken gear in the middle is in a state, and the spring 1 will accumulate mechanical power at this time. When it continues to move downward, the edge of the broken gear will slide downward along the outer wall of the rotating rod 1.

As the electric telescopic rod continues to pull downward, the yarn wheel will break, one end is at the bottom of the rotating column, and the other end is at the bottom of the extrusion column. When the sliding frame reaches the position of the groove, the broken gear loses contact with the outer wall of the rotating rod 1. At this time, the spring 1 and the spring 4 will release mechanical power, forcing the rotating column and the folding metal curtain to reset, and the reset folding metal curtain will separate from the outer wall of the rotating column and will no longer clamp the broken wire end of the yarn wheel; then the electric telescopic rod is extended, forcing the sliding frame to move upward along the outer wall of the mounting plate, and the upward sliding frame drives the driving rod 1 to move upward synchronously, and the driving rod 1 forces the gear on the right to rotate counterclockwise through the rotating rod 2, presenting a Figure 8 state, and at this time the two meshing and rotating squeezing columns will force the line end of the yarn wheel to be transmitted downward, and the line end of the yarn wheel will pass through the clamping groove again.

[0013] Preferably, the cleaning component also includes an exhaust port opened on the top of the piston plate, a fixed bracket is fixedly connected to the inner wall of the exhaust port, a spring sliding rod is slidably connected to the inner wall of the fixed bracket, and a blocking ball is fixedly connected to the bottom of the spring sliding rod. In order to solve the problem that the rotating rod 2 forces the gear to rotate, a right-angle groove 2 is provided inside the device. When the driving rod 1 moves upward, the outer wall of the rotating rod 2 contacts the inner wall of the gear, and at this time, the bottom plane of the rotating rod 2 contacts the plane of the inner wall of the gear. Therefore, when the driving rod 1 moves upward, the gear can rotate, and when the driving rod 1 moves downward, the rotating rod 2 contacts the gear and will tilt upward with the connection point as the center, presenting a Figure 9 The incomplete gear is in the middle G state, and at this time, the driving rod will no longer drive the gear to rotate when it moves down; similarly, when the incomplete gear reaches the bottom and resets, when the electric telescopic rod drives the incomplete gear to move up, the side wall of the incomplete gear will contact the bottom inclined surface of the rotating rod 1, forcing the rotating rod 1 to tilt upward with the connection point as the center. Therefore, when the incomplete gear moves up, the incomplete gear will no longer rotate. Through the application of the above components, the misalignment of components during the operation of the equipment is avoided, which affects the detection accuracy.

[0014] Preferably, the cleaning component also includes a storage box fixedly connected to the end of the air pressure box away from the mounting plate, an L-shaped plate is slidably connected to the inner wall of the storage box, an exhaust port 1 is provided on the side wall of the L-shaped plate, and an exhaust port 2 is provided on a side of the storage box close to the mounting plate, a spring telescopic rod is fixedly connected to the top of the L-shaped plate, the end of the spring telescopic rod away from the L-shaped plate is fixedly connected to the inner wall of the air pressure box, and four air injection pipes are connected to the side of the storage box away from the mounting plate. A cleaning component is arranged inside the device by utilizing the downward force of the above-mentioned sliding frame. As the electric telescopic rod descends, the bottom of the contact rod will contact the top of the base, and at this time the contact rod will drive the piston plate along The inner wall of the air pressure box moves upward and compresses the gas inside the air pressure box, making the gas inside the air pressure box form a high-pressure state. As the electric telescopic rod contracts, the top of the piston plate will contact the bottom of the L-shaped plate, forcing the L-shaped plate to move upward along the inner wall of the storage box. At this time, exhaust port 1 and exhaust port 2 will overlap to form an exhaust gap, and the high-pressure gas inside the air pressure box will enter the storage box through the above gap, and finally be sprayed on the bottom of the opened folding metal curtain through the jet pipe. Through the application of the above components, it is avoided that the broken thread head of the yarn wheel remains in the clamping groove when the folding metal curtain is extended, affecting the subsequent clamping effect.

[0015] A method for using a yarn elastic force detection device comprises the following steps:

[0016] S1: placing the yarn: installing the yarn wheel on the side wall of the mounting plate, and hanging the yarn end of the yarn wheel downward;

[0017] S2: Guide the line: Make sure the line end of the yarn wheel passes through the gap between the extrusion columns and the clamping groove, and then turn on the power of the electric telescopic rod.

[0018] The present invention has the following beneficial effects:

[0019] (1) The present invention aims to solve the problem that the clamping position of the yarn wheel may break prematurely due to the clamping force. A clamping mechanism and a detection component are arranged inside the device. Before use, the yarn wheel is installed on the side wall of the mounting plate, and the wire end of the yarn wheel is hung down, and it is ensured that the wire end of the yarn wheel passes through the gap between the extrusion columns and the clamping groove, presenting a Figure 1 The electric telescopic rod is then powered on, and the electric telescopic rod drives the sliding frame to slide downward along the outer wall of the mounting plate. During the downward movement of the rotating column, the side wall of the incomplete gear will contact the side wall of the rotating rod 1, presenting a Figure 4 At this time, the broken gear drives the driving column and the rotating column to rotate, and the rotating rotating column drives the folded metal curtain to slide along the inner wall of the sliding groove. In this process, the clamping groove drives the line segment of the yarn wheel to move synchronously, so that the folded metal curtain is wrapped around the outer wall of the rotating column, presenting a Figure 7state, at this time the line end of the yarn wheel is clamped by the rotating column and the folded metal curtain, and the top of the outer wall of the yarn wheel is clamped and restricted by the extrusion column. At this time, the electric telescopic rod continues to shrink. At this time, the yarn wheel will be pulled, and the elastic force detection process is carried out. During the detection process, the compressed position at the bottom of the yarn wheel line end is on the outer wall of the rotating column. Through the application of the above-mentioned components, when the equipment pulls the yarn wheel, the clamped position and the compressed position at the bottom of the yarn wheel are separated, thereby reducing the influence of the external clamping force on the pulling end and improving the detection accuracy of the equipment.

[0020] (2) The present invention utilizes the characteristics of the rotating column and the folded metal curtain clamping the yarn wheel line end. When the incomplete gear rotates, since the incomplete gear itself has only half the volume, this will force the incomplete gear to only drive the rotating column to rotate half a circle, and finally present the following Figure 7 The broken gear in the middle will be in the state of the broken gear, and the spring 1 will accumulate mechanical power at this time. When it continues to move downward at this time, the edge of the broken gear will slide downward along the outer wall of the rotating rod 1. Through the application of the above-mentioned components, the broken gear can be prevented from driving the driving column to rotate too long, affecting the detection accuracy of the yarn wheel; in addition, a driving component is arranged inside the equipment. As the electric telescopic rod continues to be pulled downward, the yarn wheel will break, one end is at the bottom of the rotating column, and the other end is at the bottom of the extrusion column. When the sliding frame reaches the position of the groove, the broken gear loses contact with the outer wall of the rotating rod 1. At this time, the spring 1 and the spring 4 will release the mechanical power, forcing the rotating column and the folding metal curtain to reset, and the reset folding metal curtain will be separated from the outer wall of the rotating column, and will no longer clamp the broken wire end of the yarn wheel; then the electric telescopic rod is extended, forcing the sliding frame to move upward along the outer wall of the mounting plate. At this time, the upward sliding frame drives the driving rod 1 to move upward synchronously, and the driving rod 1 forces the gear on the right to rotate counterclockwise through the rotating rod 2, presenting as shown in the figure Figure 8 state, and at this time the two meshing and rotating squeezing columns will force the line end of the yarn wheel to be transmitted downward, and the line end of the yarn wheel will pass through the clamping groove again. When the electric telescopic rod is retracted, the detection process will be carried out again. Through the application of the above components, the equipment can realize autonomous wiring, and can perform multiple tests on the first sample, thereby increasing the detection data of the equipment.

[0021] (3) In order to solve the problem that the rotating rod 2 forces the gear to rotate, the present invention provides a right-angle groove 2 inside the device. When the driving rod 1 moves upward, the outer wall of the rotating rod 2 contacts the inner wall of the gear, and at this time, the bottom plane of the rotating rod 2 contacts the inner wall plane of the gear. Therefore, when the driving rod 1 moves upward, the gear can rotate. When the driving rod 1 moves downward, the rotating rod 2 contacts the gear and will tilt upward with the connection point as the center, presenting a Figure 9The incomplete gear is in the middle G state, and at this time, the driving rod will no longer drive the gear to rotate when it moves down; similarly, when the incomplete gear reaches the bottom and resets, when the electric telescopic rod drives the incomplete gear to move up, the side wall of the incomplete gear will contact the bottom inclined surface of the rotating rod 1, forcing the rotating rod 1 to tilt upward with the connection point as the center. Therefore, when the incomplete gear moves up, the incomplete gear will no longer rotate. Through the application of the above components, the misalignment of the components during the operation of the equipment is avoided, which affects the detection accuracy. In addition, when the equipment is running, the spring 2 drives the L-shaped rod to limit the two gears, so as to avoid the gears from rotating at a small angle when the yarn wheel is subjected to tension, which affects the detection accuracy of the equipment.

[0022] (4) The present invention utilizes the downward force of the above-mentioned sliding frame and is provided with a cleaning component inside the device. As the electric telescopic rod descends, the bottom of the contact rod will contact the top of the base, and at this time the contact rod will drive the piston plate to move upward along the inner wall of the air pressure box and compress the gas inside the air pressure box, so that the gas inside the air pressure box forms a high-pressure state. As the electric telescopic rod contracts, the top of the piston plate will contact the bottom of the L-shaped plate, forcing the L-shaped plate to move upward along the inner wall of the storage box. At this time, exhaust port 1 and exhaust port 2 will overlap to form an exhaust gap, and the high-pressure gas inside the air pressure box will enter the storage box through the above gap, and finally be sprayed on the bottom of the opened folding metal curtain through the jet pipe. By using the above-mentioned components, it is avoided that when the folding metal curtain is extended, the broken thread ends of the yarn wheel remain in the clamping groove, affecting the subsequent clamping effect.

During the detection process, the compressed position at the bottom of the line end of the yarn wheel 21 is on the outer wall of the rotating column 34. Through the application of the above-mentioned components, when the equipment pulls the yarn wheel 21, the clamped position and the compressed position at the bottom of the yarn wheel 21 are separated, thereby reducing the influence of the external clamping force on the pulling end and improving the detection accuracy of the equipment.

[0048] For example 2, please refer to Figure 8 - Fig.14 The present invention is a yarn elastic force detection device. On the basis of the first embodiment, the driving component 4 includes a driving rod 41 fixedly connected to the top of the sliding frame 31, and a plurality of right-angle grooves 42 are provided on the side wall of the driving rod 41. The inner walls of the plurality of right-angle grooves 42 are rotatably connected with a rotating rod 43. A mounting frame 44 is fixedly connected to the side wall of the mounting plate 1, and an L-shaped rod 45 is slidably connected to the inner wall of the mounting frame 44. A spring 46 is fixedly connected to the bottom of the L-shaped rod 45, and a cleaning component 5 is fixedly connected to the bottom of the sliding frame 31. By utilizing the characteristics of the rotating column 34 and the folded metal curtain 35 clamping the end of the yarn wheel 21, when the incomplete gear 38 rotates, since the incomplete gear 38 itself has only half the volume, this will force the incomplete gear 38 to only drive the rotating column 34 to rotate half a circle, and finally present as shown below. Figure 7The broken gear 38 is in the state of the broken gear 38, and the spring 1 313 will accumulate mechanical power at this time. When it continues to move downward, the edge of the broken gear 38 will slide downward along the outer wall of the rotating rod 1 312. Through the application of the above components, the broken gear 38 can be prevented from driving the driving column 37 to rotate too long, which will affect the detection accuracy of the yarn wheel 21.

[0049] The cleaning component 5 includes an air pressure box 51 fixedly connected to the bottom of the sliding frame 31, a piston plate 52 is slidably connected to the inner wall of the air pressure box 51, a contact rod 53 is fixedly connected to the bottom of the piston plate 52, a pulling line 54 is fixedly connected to the bottom of the contact rod 53, and the pulling line 54 is fixedly connected to the top of the base 11 at one end away from the contact rod 53. A driving component 4 is arranged inside the device. As the electric telescopic rod 12 continues to pull downward, the yarn wheel 21 will break, one end is at the bottom of the rotating column 34, and the other end is at the bottom of the extrusion column 23. When the sliding frame 31 reaches the position of the groove 310, the incomplete yarn wheel 21 will break. The gear 38 loses contact with the outer wall of the rotating rod 1 312.

The reset folding metal curtain 35 will separate from the outer wall of the rotating column 34 and will no longer clamp the broken wire end of the yarn wheel 21. Then the electric telescopic rod 12 will extend, forcing the sliding frame 31 to move upward along the outer wall of the mounting plate 1.

In order to solve the problem that the rotating rod 23 forces the gear 22 to rotate, a right-angle groove 242 is provided inside the device. When the driving rod 1 41 moves upward, the outer wall of the rotating rod 243 contacts the inner wall of the gear 22, and at this time, the bottom plane of the rotating rod 243 contacts the inner wall plane of the gear 22. Therefore, when the driving rod 1 41 moves upward, the gear 22 can rotate, and when the driving rod 1 41 moves downward, the rotating rod 243 contacts the gear 22 and will tilt upward with the connection point as the center, presenting a Figure 9In the middle G state, the driving rod 41 moves downward and will no longer drive the gear 22 to rotate; similarly, when the incomplete gear 38 reaches the bottom and resets, when the electric telescopic rod 12 drives the incomplete gear 38 to move upward, the side wall of the incomplete gear 38 will contact the bottom inclined surface of the rotating rod 312, forcing the rotating rod 312 to tilt upward with the connection point as the center. Therefore, when the incomplete gear 38 moves upward, the incomplete gear 38 will no longer rotate. Through the application of the above components, the misalignment of the components during the operation of the equipment is avoided, which affects the detection accuracy.

[0051] The cleaning component 5 also includes a storage box 59 fixedly connected to the end of the air pressure box 51 away from the installation disk 1, an L-shaped plate 510 is slidably connected to the inner wall of the storage box 59, an exhaust port 1 511 is provided on the side wall of the L-shaped plate 510, and an exhaust port 2 512 is provided on the side of the storage box 59 close to the installation disk 1, a spring telescopic rod 513 is fixedly connected to the top of the L-shaped plate 510, and the end of the spring telescopic rod 513 away from the L-shaped plate 510 is fixedly connected to the inner wall of the air pressure box 51, and four air injection pipes 514 are connected to the side of the storage box 59 away from the installation disk 1. By utilizing the downward force of the above-mentioned sliding frame 31, a cleaning component 5 is arranged inside the device. As the electric telescopic rod 12 descends, the bottom of the contact rod 53 will contact the top of the base 11, and at this time the contact rod 53 will drive The piston plate 52 moves upward along the inner wall of the air pressure box 51 and compresses the gas inside the air pressure box 51, so that the gas inside the air pressure box 51 forms a high-pressure state. As the electric telescopic rod 12 contracts, the top of the piston plate 52 will contact the bottom of the L-shaped plate 510, forcing the L-shaped plate 510 to move upward along the inner wall of the storage box 59. At this time, the exhaust port 1 511 and the exhaust port 2 512 will overlap to form an exhaust gap, and the high-pressure gas inside the air pressure box 51 will enter the storage box 59 through the above gap, and finally be sprayed on the bottom of the opened folding metal curtain 35 through the jet pipe 514. Through the application of the above components, it is avoided that when the folding metal curtain 35 is extended, the broken thread end of the yarn wheel 21 still remains in the clamping groove 36, affecting the subsequent clamping effect.

[0052] The method for using the yarn elastic force testing device includes the following steps:

[0053] S1: placing the yarn: installing the yarn wheel 21 on the side wall of the mounting plate 1, and hanging the yarn end of the yarn wheel 21 downward;

[0054] S2: Guiding line: ensure that the thread end of the yarn wheel 21 passes through the gap between the squeezing columns 23 and the clamping groove 36, and then turn on the power of the electric telescopic rod 12.

[0055] A specific application of this embodiment is: before use, the yarn wheel 21 is installed on the side wall of the mounting plate 1, the thread end of the yarn wheel 21 is hung down, and it is ensured that the thread end of the yarn wheel 21 passes through the gap between the extrusion columns 23 and the clamping groove 36, presenting as shown in Figure 1 The electric telescopic rod 12 is then powered on, and the electric telescopic rod 12 drives the sliding frame 31 to slide downward along the outer wall of the mounting plate 1. During the downward movement of the rotating column 34, the side wall of the incomplete gear 38 will contact the side wall of the rotating rod 1 312, presenting a Figure 4 At this time, the incomplete gear 38 drives the driving column 37 and the rotating column 34 to rotate, and the rotating rotating column 34 drives the folded metal curtain 35 to slide along the inner wall of the sliding groove 33. In this process, the clamping groove 36 drives the line segment of the yarn wheel 21 to move synchronously, so that the folded metal curtain 35 is wrapped around the outer wall of the rotating column 34, presenting as shown in FIG. Figure 7 state, at this time, the line end of the yarn wheel 21 is clamped by the rotating column 34 and the folded metal curtain 35, and the top of the outer wall of the yarn wheel 21 is clamped and restricted by the extrusion column 23. At this time, the electric telescopic rod 12 continues to shrink. At this time, the yarn wheel 21 will be pulled and the elastic force detection process is carried out. During the detection process, the compressed position at the bottom of the line end of the yarn wheel 21 is on the outer wall of the rotating column 34. Through the application of the above-mentioned components, when the equipment pulls the yarn wheel 21, the clamped position and the compressed position at the bottom of the yarn wheel 21 are separated, thereby reducing the influence of the external clamping force on the pulling end and improving the detection accuracy of the equipment.

[0056] By utilizing the characteristics of the rotating column 34 and the folded metal curtain 35 clamping the yarn wheel 21, when the incomplete gear 38 rotates, since the incomplete gear 38 itself has only half the volume, this will force the incomplete gear 38 to only drive the rotating column 34 to rotate half a circle, and finally present as shown in the following figure: Figure 7The broken gear 38 is in the state of the broken gear 38, and the spring 1 313 will accumulate mechanical power at this time. When it continues to move downward at this time, the edge of the broken gear 38 will slide downward along the outer wall of the rotating rod 1 312. Through the application of the above-mentioned components, the broken gear 38 is prevented from driving the driving column 37 to rotate too long, which affects the detection accuracy of the yarn wheel 21. In addition, a driving component 4 is provided inside the device. As the electric telescopic rod 12 continues to be pulled downward, the yarn wheel 21 will break, with one end at the bottom of the rotating column 34 and the other end at the bottom of the extrusion column 23. When the sliding frame 31 reaches the position of the groove 310, The broken gear 38 loses contact with the outer wall of the rotating rod 1 312. At this time, the spring 1 313 and the spring 4 315 will release the mechanical power, forcing the rotating column 34 and the folding metal curtain 35 to reset, and the reset folding metal curtain 35 will separate from the outer wall of the rotating column 34, and will no longer clamp the broken wire end of the yarn wheel 21; then the electric telescopic rod 12 will extend, forcing the sliding frame 31 to move upward along the outer wall of the mounting plate 1. At this time, the upward sliding frame 31 drives the driving rod 1 41 to move upward synchronously, and the driving rod 1 41 forces the gear 22 on the right side to rotate counterclockwise through the rotating rod 2 43, presenting as shown in the figure. Figure 8 state, and at this time the two meshing and rotating squeezing columns 23 will force the line end of the yarn wheel 21 to be transmitted downward, and the line end of the yarn wheel 21 will pass through the clamping groove 36 again. When the electric telescopic rod 12 is retracted, the detection process will be performed again. Through the application of the above components, the equipment can realize autonomous wiring, and can perform multiple tests on the first sample, thereby increasing the detection data of the equipment.

[0057] In order to solve the problem that the rotating rod 43 forces the gear 22 to rotate, a right-angle groove 42 is provided inside the device. When the driving rod 41 moves upward, the outer wall of the rotating rod 43 contacts the inner wall of the gear 22, and at this time, the bottom plane of the rotating rod 43 contacts the inner wall plane of the gear 22. Therefore, when the driving rod 41 moves upward, the gear 22 can rotate. When the driving rod 41 moves downward, the rotating rod 43 contacts the gear 22 and will tilt upward with the connection point as the center, presenting a Figure 9 In the middle G state, the driving rod 41 moves downward and will no longer drive the gear 22 to rotate; similarly, when the incomplete gear 38 reaches the bottom and resets, when the electric telescopic rod 12 drives the incomplete gear 38 to move upward, the side wall of the incomplete gear 38 will contact the bottom inclined surface of the rotating rod 312, forcing the rotating rod 312 to tilt upward with the connection point as the center. Therefore, when the incomplete gear 38 moves upward, the incomplete gear 38 will no longer rotate. Through the application of the above-mentioned components, the misalignment of the components during the operation of the equipment is avoided, which affects the detection accuracy. In addition, when the equipment is running, the spring 2 46 drives the L-shaped rod 45 to limit the two gears 22, so as to avoid the gear 22 from rotating at a small angle when the yarn wheel 21 is subjected to tension, which affects the detection accuracy of the equipment.

[0058] By utilizing the downward force of the sliding frame 31, a cleaning assembly 5 is provided inside the device. As the electric telescopic rod 12 descends, the bottom of the contact rod 53 will contact the top of the base 11, and at this time, the contact rod 53 will drive the piston plate 52 to move upward along the inner wall of the air pressure box 51, and compress the gas inside the air pressure box 51, so that the gas inside the air pressure box 51 forms a high-pressure state. As the electric telescopic rod 12 contracts, the top of the piston plate 52 will contact the bottom of the L-shaped plate 510, forcing the L The mold plate 510 moves upward along the inner wall of the storage box 59. At this time, the exhaust port 1 511 and the exhaust port 2 512 will overlap to form an exhaust gap, and the high-pressure gas inside the air pressure box 51 will enter the storage box 59 through the above gap, and finally be sprayed on the bottom of the opened folding metal curtain 35 through the jet pipe 514. Through the application of the above components, it is avoided that the broken thread ends of the yarn wheel 21 remain in the clamping groove 36 when the folding metal curtain 35 is extended, thereby affecting the subsequent clamping effect.

[0059] In the process of the sliding frame 31 moving upward, as the distance between the base 11 and the sliding groove 33 increases, the pulling line 54 will force the contact rod 53 and the piston plate 52 to slide downward. At this time, under the push of the spring telescopic rod 513, the exhaust port 1 511 and the exhaust port 2 512 are misaligned again, so that a closed space is formed inside the air pressure box 51 again. When the piston plate 52 continues to move downward, a negative pressure environment will be formed inside the air pressure box 51. The negative pressure will force the blocking ball 58 to move upward, so that the external gas enters the air pressure box 51 through the gap between the blocking ball 58 and the exhaust port 55.
