Description

Technical Field

[0001] This invention relates to the technical field of support and hanger testing equipment, specifically to a seismic support and hanger testing machine. Background Technology

[0002] Seismic bracing is a type of support system used to support and secure drainage pipes, ventilation ducts, gas pipes, or electrical pipes in buildings. It possesses a certain degree of earthquake resistance to protect the installed pipes from easy earthquake damage and reduce secondary disasters. To verify whether the strength of the seismic bracing meets design requirements, mechanical testing is necessary.

[0003] When conducting seismic tests on supports and hangers, the supports and hangers are installed on the testing machine, and then the motor is started to generate a pushing force on the supports and hangers using an electric actuator. However, this test is a one-way, one-point test, which makes the final test results inaccurate and cannot ensure the safety of the supports and hangers in subsequent use. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a seismic bracing and hanger testing machine, including a fixing mechanism, the fixing mechanism further including a base, four support columns fixedly connected to the top of the base, a cover plate fixedly connected to the top of the four support columns, a box fixedly connected to the top of the base, an electric push rod slidably connected to the inner wall of the box, a fixing clamp fixedly connected to the outer wall of the electric push rod, and a hanger fixedly connected to the bottom of the cover plate. The invention is characterized by further including: The thrust mechanism is slidably connected to the inner wall of the housing and is used to test the hanger; The control mechanism is fixedly connected to the outer wall of the electric push rod; it is used to test different positions of the hanger. The extrusion mechanism is slidably connected to the outer wall of the thrust mechanism; it is used to generate pressure on the hanger.

[0005] Preferably, the thrust mechanism includes: The thrust assembly is slidably connected to the inner wall of the housing; A rotating assembly is fixedly connected to the outer wall of the thrust assembly; When the electric actuator is activated, it drives the thrust assembly to move.

[0006] Preferably, the control mechanism includes: A rotating assembly is fixedly connected to the outer wall of the electric actuator; A limiting component is fixedly connected to the outer wall of the rotating component; When the electric actuator moves backward, the rotating component causes the rotary component to rotate.

[0007] Preferably, the extrusion mechanism includes: The connecting component is slidably connected to the outer wall of the rotating component; The contact component is fixedly connected to the outer wall of the connecting component; When the electric actuator starts to move, the rotating component will also start to drive the connecting component to move. At this time, the fixing clamp and contact component will test the hanger.

[0008] Preferably, the thrust assembly includes a thrust frame slidably connected to the inner wall of the housing, a connecting block slidably connected to the inner wall of the thrust frame, a spring fixedly connected to the outer wall of the connecting block, the end of the spring away from the connecting block being fixedly connected to the inner wall of the thrust frame, and the outer wall of the connecting block being fixedly connected to the output end of the electric push rod. When the electric push rod is activated, it drives the connecting block to move outward synchronously. When the connecting block contacts the inner wall of the thrust frame, it drives the thrust frame to move in the same direction. In the initial state, the spring is in a semi-compressed state.

[0009] Preferably, the rotating assembly includes a fixed rod fixedly connected to the side of the thrust frame near the housing, a rotating rod rotatably connected to the outer wall of the fixed rod, and a locking block fixedly connected to the outer wall of the thrust frame; During the return stroke of the electric push rod, the control mechanism moves backward. This backward movement of the control mechanism causes the rotating rod to rotate. A locking block six is ​​fixedly connected to the end of the rotating rod near the electric push rod.

[0010] Preferably, the rotating assembly includes a connecting block two fixedly connected to the outer wall of the electric push rod, and a rotating block is fixedly connected to the outer wall of the connecting block two; When the electric push rod returns to its original position, the second connecting block will contact the rotating block, causing the second connecting block to drive the rotating block to move horizontally along the direction of the electric push rod's return.

[0011] Preferably, the limiting component includes a second locking block rotatably connected to the outer wall of the rotating block, and a first counterweight fixedly connected to the outer wall of the rotating rod; The second locking block consists of a triangular block, an arc-shaped plate, and a protrusion on the outer wall of the arc-shaped plate. The second locking block is equipped with a torsion spring. In the initial state, the rotating rod is attached to the bottom of the triangular inclined surface on the second locking block.

[0012] Preferably, the connecting assembly includes a push bar slidably connected to the outer wall of the rotating rod, a counterweight block two rotatably connected to the outer wall of the push bar, a positioning block fixedly connected to the outer wall of the push bar, a spring two fixedly connected to the outer wall of the push bar, a push bar two fixedly connected to the end of the spring two away from the push bar, and the inner wall of the positioning block slidably connected to the outer wall of the push bar two.

[0013] When the electric push rod returns to its original position, it drives the rotating block to move. At this time, one end of the rotating rod will start to tilt up along the inclined surface on the rotating block, causing the rotating rod to rotate. The push bar will be affected by the gravity of the second counterweight and will slide down along the outer wall of the rotating rod. The second counterweight is lighter than the first counterweight. When the second counterweight moves to the end away from the electric push rod, the rotating rod on one side of the second counterweight will descend, and the other end of the rotating rod will rise. The push bar can only slide laterally on the outer wall of the rotating rod and cannot rotate.

[0014] Preferably, the contact assembly includes a front push block fixedly connected to the bottom of the push bar two, a telescopic block fixedly connected to the bottom of the front push block, a rear push block slidably connected to the outer wall of the telescopic block at the end away from the push block, a locking block three fixedly connected to the inner wall of the positioning block, a rotating strip rotatably connected to the inner wall of the rear push block, a pressure plate slidably connected to the outer wall of the push bar two, and a contact plate fixedly connected to the outer wall. When the electric push rod returns, it will drive the fixing clamp and the hanger to move in the same direction. Because the pressure plate is stuck between the push bar two and the push bar, the pressure on the contact plate and the hanger contact position will increase. The bottom of the pressure plate is connected to the positioning block by a spring three. A triangular block is fixedly connected to the outer wall of the front push block. A locking block five is fixedly connected to the bottom of the pressure plate. The rotating bar is made of flexible plastic material. The rotating bar will bend when subjected to greater pressure. The rotating bar can only rotate clockwise in one direction.

[0015] The present invention has the following beneficial effects: (1) In the second return stroke, because the push block will not hold the push bar two by the pressure plate, the push bar cannot be subjected to the force generated by the hanger on the push bar two. When the connecting block two returns with the electric push rod, the rotating block will cause the rotating rod to tilt, and the push bar will also tilt. At this time, the push bar will be affected by the counterweight block two, and the push bar will move away from the electric push rod. In this way, the contact plate can detect multiple positions of the hanger, expand the detection range, and improve the detection accuracy.

[0016] (2) When the electric push rod returns for the second time, the triangular block at the bottom of the front push block is at the left end of the rotating bar. This will prevent the front push block from pushing the second push bar when the subsequent hanger squeezes it. The second push bar, squeezed by the hanger, will compress the second spring. At the same time, the pressure plate will also be pushed down by the second push bar. The reaction force of the pressure plate on the hanger will decrease. When the third push is performed, the second spring will release potential energy, causing the second push bar to move away from the push bar. At the same time, when the triangular block under the front push block contacts the rotating bar, the rotating bar will be twisted. The torsion spring inside the rotating bar will also start to accumulate potential energy. When the triangular block under the front push block passes the rotating bar, the torsion spring inside the rotating bar will release potential energy and return to the initial state. This will change the reaction force generated by the pressure plate each time the hanger contacts the pressure plate. By analyzing the alternating large and small loads in this way, the actual working safety threshold of the hanger can be found more quickly.

[0017] (3) In this invention, when the push bar 2 and the contact plate follow the electric push rod for the first return stroke, the push bar 2 will carry the front push block to make the rear push block contact the locking block 5 on the outer wall of the pressure plate, so that the pressure plate is locked by the rear push block and the push bar 2 can no longer move backward. At this time, the hanger moves backward with the fixed clamp. When the hanger contacts the contact plate, the reaction force generated by the contact plate on the hanger will increase. In this way, the interference caused by aftershocks or constraints during the structure rebound recovery is detected and simulated, thereby improving the detection accuracy.

[0018] (4) By sliding the push bar on the rotating rod, the present invention makes the contact plate detect multiple positions of the hanger, so that the hanger will be squeezed at multiple points in a real earthquake. In this way, the continuous deformation capacity and integrity of the hanger and other components are tested, and the force transmitted to the inside of the hanger is evaluated to determine whether it will lead to buckling or instability.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Example 1, please refer to Figures 1-6The present invention is a seismic support and hanger testing machine, including a fixing mechanism 1, the fixing mechanism 1 further includes a base 12, four support columns 13 are fixedly connected to the top of the base 12, a cover plate 14 is fixedly connected to the top of the four support columns 13, a box body 15 is fixedly connected to the top of the base 12, an electric push rod 16 is slidably connected to the inner wall of the box body 15, a fixing clamp 18 is fixedly connected to the outer wall of the electric push rod 16, and a hanger 17 is fixedly connected to the bottom of the cover plate 14. Thrust mechanism 2 is slidably connected to the inner wall of housing 15 and is used to test hanger 17; Control mechanism 3 is fixedly connected to the outer wall of electric push rod 16; used to test different positions of hanger 17. The extrusion mechanism 4 is slidably connected to the outer wall of the thrust mechanism 2; it is used to generate pressure on the hanger 17.

[0024] Thrust mechanism 2 includes: Thrust assembly 21 is slidably connected to the inner wall of housing 15; Rotating component 22 is fixedly connected to the outer wall of thrust component 21; When the electric push rod 16 is activated, it will drive the thrust assembly 21 to move.

[0025] Example 2, please refer to Figures 2-11 This invention is a seismic bracing testing machine. Based on Example 1, the control mechanism 3 includes: Rotating component 31 is fixedly connected to the outer wall of electric push rod 16; Limiting component 32 is fixedly connected to the outer wall of rotating component 22; When the electric push rod 16 moves backward, the rotating component 22 causes the rotating component 31 to rotate.

[0026] The extrusion mechanism 4 includes: Connecting component 41 is slidably connected to the outer wall of rotating component 22; Contact component 42 is fixedly connected to the outer wall of connection component 41; When the electric push rod 16 starts to move, the rotating component 22 will also start to drive the connecting component 41 to move. At this time, the fixing clamp 18 and the contact component 42 will test the hanger 17.

[0027] The thrust assembly 21 includes a thrust frame 211 slidably connected to the inner wall of the housing 15, a connecting block 213 slidably connected to the inner wall of the thrust frame 211, a spring 212 fixedly connected to the outer wall of the connecting block 213, the end of the spring 212 away from the connecting block 213 being fixedly connected to the inner wall of the thrust frame 211, and the outer wall of the connecting block 213 being fixedly connected to the outer wall of the electric push rod 16. When the electric push rod 16 is activated, the connecting block 213 will also start to move as the electric push rod 16 begins to move. When the connecting block 213 contacts the inner wall of the push frame 211, it will move the push frame 211 forward as well. In the initial state, the spring 212 is in a semi-compressed state.

[0028] The rotating assembly 22 includes a fixed rod 221 fixedly connected to one end of the thrust frame 211 near the housing 15, a rotating rod 222 rotatably connected to the outer wall of the fixed rod 221, and a locking block 223 fixedly connected to the outer wall of the thrust frame 211. When the electric push rod 16 returns to its original position, it will drive the control mechanism 3 to move backward. At this time, the backward movement of the control mechanism 3 will cause the rotating rod 222 to rotate. The end of the rotating rod 222 near the electric push rod 16 is fixedly connected to a locking block six.

[0029] The rotating assembly 31 includes a connecting block 311 fixedly connected to the outer wall of the electric push rod 16, and a rotating block 312 fixedly connected to the outer wall of the connecting block 311. When the electric push rod 16 returns to its original position, the connecting block 311 will contact the rotating block 312, causing the connecting block 311 to drive the rotating block 312 to move horizontally along the direction of the electric push rod 16's return stroke.

[0030] The limiting component 32 includes a second locking block 321 rotatably connected to the outer wall of the rotating block 312, and a first counterweight 322 fixedly connected to the outer wall of the rotating rod 222. Among them, the second locking block 321 consists of a triangular block, an arc-shaped plate, and a protrusion on the outer wall of the arc-shaped plate. The second locking block 321 contains a torsion spring 2, which appears as follows: Figure 4 In its initial state, the rotating rod 222 is attached to the bottom of the triangular inclined surface on the second locking block 321; the second locking block 321 will... Figure 4 Rotate counterclockwise in one direction with K as the center.

[0031] The connecting assembly 41 includes a push bar 411 slidably connected to the outer wall of the rotating rod 222, a counterweight 412 rotatably connected to the outer wall of the push bar 411, a positioning block 413 fixedly connected to the outer wall of the push bar 411, a spring 415 fixedly connected to the outer wall of the push bar 411, and a push bar 414 fixedly connected to the end of the spring 415 away from the push bar 411. The inner wall of the positioning block (413) is slidably connected to the outer wall of the push bar 414. During the second return stroke, because the push block 423 will not hold the push bar 414 in place by the pressure plate 426, the push bar 411 will not be subject to the force exerted by the hanger 17 on the push bar 414. When the connecting block 311 returns with the electric push rod 16, the rotating block 321 will cause the rotating rod 222 to tilt, and the push bar 411 will also tilt. At this time, the push bar 411 will be affected by the counterweight block 412, and the push bar 411 will move away from the electric push rod 16. In this way, the contact plate 427 can detect multiple positions of the hanger 17, thus expanding the detection range.

[0032] The contact assembly 42 includes a front push block 421 fixedly connected to the outer wall of the push bar 414, a telescopic block 422 fixedly connected to the outer wall of the front push block 421, a rear push block 423 slidably connected to the outer wall of the telescopic block 422 at the end away from the push block 421, a locking block 424 fixedly connected to the inner wall of the positioning block 413, a rotating strip 425 rotatably connected to the inner wall of the rear push block 423, a pressure plate 426 slidably connected to the outer wall of the push bar 414, and a contact plate 427 fixedly connected to the outer wall of the push bar 414. When the electric push rod 16 returns for the second time, the triangular block at the bottom of the front push block 421 is at the left end of the rotating bar 425. At this time, when the rear hanger 17 squeezes the push bar 414, the front push block 421 will no longer drive the rear push block 423 into the space below the pressure plate 426. At this time, the push bar 414, squeezed by the hanger 17, will compress the spring 415. At the same time, the pressure plate 426 will also move downward under the pushing force of the push bar 414. At this time, the reaction force of the pressure plate 426 on the hanger 17 will decrease. When the third push stroke is performed, the spring 415 will release potential energy, causing the push bar 414 to move downward. 4. Move away from push bar 411. At the same time, when the triangular block under the push block 421 contacts the rotating bar 425, the rotating bar 425 will be twisted. The torsion spring inside the rotating bar 425 will also start to accumulate potential energy. When the triangular block under the push block 421 passes the rotating bar 425, the torsion spring inside the rotating bar 425 will release potential energy and return to the initial state. This will change the reaction force generated by the pressure plate 426 each time the hanger 17 contacts the pressure plate 426. By analyzing the alternating action of large and small loads in this way, the actual working safety threshold of the hanger 17 can be found more quickly.

[0033] A specific application of this embodiment is as follows: At the start of work, the operator first fixes the hanger 17 between the bottom of the cover plate 14 and the fixing clamp 18, and secures the hanger 17 by turning the screws on the fixing clamp 18. Then, the motor inside the housing 15 is started, causing the electric push rod 16 to begin moving horizontally. When the electric push rod 16 begins to move away from the housing 15, the connecting block 213 will also move along the direction of the electric push rod 16, along with the thrust frame 211. At this time, the contact plates 427 at both ends will also apply pressure to the hanger 17. When the electric push rod 16 begins to return, the connecting block 213 will compress the spring 212 and accumulate elastic potential energy. At this time, the connecting block 213 is affected by the elastic potential energy, and the thrust frame 211 will move backward. As the displacement decreases, the pressure of the contact plate 427 on the push bar 411 on the hanger 17 decreases. When the electric push rod 16 continues to move backward, the connecting block 2 311 will push the moving block 312 to slide. When the moving block 312 slides, the rotating block 321 will also begin to slide. The rotating rod 222 at the bottom of the inclined surface of the rotating block 321 will begin to rotate around the fixed rod 221 as the counterweight 1 322 moves. The push bar 411 will also begin to tilt. During the first return stroke, the contact plate 427 will be squeezed by the hanger 17 during the return stroke. At this time, the push bar 2 414 will also begin to move towards the compression spring 2 415. When the push bar 2 414 moves, it will carry the front push block 421 and the telescopic block 422. When the triangular block on 21 contacts the rotating bar 425, the rotating bar 425 is pushed by the front push block 421. When the rear push block 423 contacts the locking block five at the bottom of the pressure plate 426, the rear push block 423 is locked. At this time, when the push bar 2 414 moves backward, the triangular block at the bottom of the front push block 421 will generate a pushing force on the rotating bar 425. This will cause the rotating bar 425 to bend first. Then, when the triangular block at the bottom of the front push block 421 passes over the rotating bar 425, it will return to its original shape. Because the pressure plate 426 is locked by the rear push block 423, the pressure plate 426 cannot slide downward again due to the pressure of the push bar 2 414. This will cause the push bar 2 414 to generate a reaction force on the surface of the hanger 17. When the return stroke of the electric push rod 16 ends, the second push stroke begins. At this time, because the electric push rod 16 will move in the opposite direction again, the triangular block at the bottom of the front push block 421 is to the left of the rotating bar 425. When the pressure plate 426 contacts the hanger 17, this will reduce the pressure on the pressure plate 426 for the second time. When the electric push rod 16 returns for the second time, the pressure generated by the hanger 17 will cause the push bar 414 to compress the spring 415 and accumulate potential energy. At this time, the triangular block on the outer wall of the front push block 421 is to the left of the rotating bar 425. When the push bar 414 moves, it will not drive the rear push block 423 to move. At this time, the push bar 414 will push the rotating bar 425 downward, causing the push bar 414 to compress the spring 415 and cause the spring 415 to accumulate potential energy. When the electric push rod 16 performs the third push stroke...Spring 415 releases elastic potential energy, causing push bar 414 to move away from push bar 414. At this time, front push block 421 moves along with push bar 414. When the triangular block on the outer wall of front push block 421 contacts rotating bar 425, it causes rotating bar 425 to rotate, so that the triangular block at the bottom of front push block 421 moves back to the right side of rotating bar 425. When waiting for the third return stroke of electric push rod 16, rear push block 423 will again lock push bar 414 through pressure plate 426, increasing the reaction force on hanger 17.

[0034] During the second return stroke, since push bar 411 is not blocked by pressure plate 426, push bar 411 will tilt due to the movement of rotating block 321. Counterweight block 412 will provide a downward force to push bar 411. Under the influence of the gravity of counterweight block 412, push bar 411 will begin to move away from electric push rod 16. During the pushing process, rotating block 321 and connecting block 311 move outward synchronously under the push of electric push rod 16. At this time, rotating rod 222 will move diagonally downward along the inclined plane due to the weight of counterweight block 322, so that rotating rod 222 returns to the horizontal state. At this time, the pressing position of pressure plate 426 on hanger 17 changes. When push bar 411 moves... When the electric push rod 222 reaches the other end away from the electric push rod 16, it will tilt due to the influence of the counterweight 412. At this time, the locking block 6 on the electric push rod 222 will contact the protrusion on the rotating block 321 when the electric push rod 16 returns. The rotating block 321 will be locked and rotate. Because the bottom of the electric push rod 222 will lack support due to the rotation of the rotating block 321, the electric push rod 222 will be affected by the counterweight 322 and rotate in the opposite direction again, causing the push bar 411 to move towards the electric push rod 16. When the electric push rod 16 pushes, the torsion spring inside the rotating block 321 will release elastic potential energy and lift the electric push rod 222 again.

[0035] By setting the push bar 414 and contact plate 427 to perform the first return stroke following the electric push rod 16, the push bar 414 will carry the front push block 421 to make the rear push block 423 contact the locking block 5 on the outer wall of the pressure plate 426, so that the pressure plate 426 is locked by the rear push block 423, preventing the push bar 414 from moving backward. At this time, the hanger 17 moves backward with the fixing clamp 18. When the hanger 17 contacts the contact plate 427, the reaction force generated by the contact plate 427 on the hanger 17 will increase. In this way, the interference caused by aftershocks or constraints during the structural rebound recovery is detected and simulated, thereby improving the detection accuracy.

[0036] When the electric push rod 16 returns for the second time, the triangular block at the bottom of the front push block 421 is at the left end of the rotating bar 425. This prevents the front push block 421 from driving the rear push block 423 under the pressure plate 426 when the subsequent hanger 17 presses the push bar 414. At this time, the push bar 414, pressed by the hanger 17, will compress the spring 415. Simultaneously, the pressure plate 426 will also move downward under the pushing force of the push bar 414. At this time, the reaction force of the pressure plate 426 on the hanger 17 will decrease. When the third push stroke is performed, the spring 415 will release potential energy, causing the push bar 414 to... 4. Move away from push bar 411. At the same time, when the triangular block under the push block 421 contacts the rotating bar 425, the rotating bar 425 will be twisted. The torsion spring inside the rotating bar 425 will also start to accumulate potential energy. When the triangular block under the push block 421 passes the rotating bar 425, the torsion spring inside the rotating bar 425 will release potential energy and return to the initial state. This will change the reaction force generated by the pressure plate 426 each time the hanger 17 contacts the pressure plate 426. By analyzing the alternating action of large and small loads in this way, the actual working safety threshold of the hanger 17 can be found more quickly.

[0037] During the second return stroke, because the push block 423 will not hold the push bar 414 in place by the pressure plate 426, the push bar 411 will not be subject to the force exerted by the hanger 17 on the push bar 414. When the connecting block 311 returns with the electric push rod 16, the rotating block 321 will cause the rotating rod 222 to tilt, and the push bar 411 will also tilt. At this time, the push bar 411 will be affected by the counterweight block 412, and the push bar 411 will move away from the electric push rod 16. In this way, the contact plate 427 can detect multiple positions of the hanger 17, thus expanding the detection range.

[0038] By sliding the push bar 411 on the rotating rod 222, the contact plate 427 detects multiple positions of the hanger 17, simulating that the hanger 17 will be compressed at multiple points in a real earthquake. In this way, the continuous deformation capacity and integrity of the hanger 17 and other components are tested, and whether the force transmitted to the inside of the hanger 17 will lead to buckling or instability is assessed.

When the electric push rod (16) returns, it will drive the control mechanism (3) to move backward. At this time, the control mechanism (3) moving backward will cause the rotating rod (222) to rotate. The end of the rotating rod (222) near the electric push rod (16) is fixedly connected to a locking block six.

7. The seismic bracing and hanger testing machine according to claim 6, characterized in that: The rotating assembly (31) includes a connecting block two (311) fixedly connected to the outer wall of the electric push rod (16), and a rotating block (312) is fixedly connected to the outer wall of the connecting block two (311). When the electric push rod (16) returns, the connecting block two (311) will contact the rotating block (312), causing the connecting block two (311) to drive the rotating block (312) and move it horizontally along the direction of the electric push rod (16)'s return.

8. The seismic bracing and hanger testing machine according to claim 7, characterized in that: The limiting component (32) includes a second locking block (321) rotatably connected to the outer wall of the rotating block (312), and a first counterweight block (322) is fixedly connected to the outer wall of the rotating rod (222).

In the initial state, the rotating rod (222) is attached to the bottom of the triangular inclined surface on the second card block (321).

9. A seismic bracing testing machine according to claim 6, characterized in that: The connecting assembly (41) includes a push bar (411) slidably connected to the outer wall of the rotating rod (222), a counterweight block (412) rotatably connected to the outer wall of the push bar (411), a positioning block (413) fixedly connected to the outer wall of the push bar (411), a spring (415) fixedly connected to the outer wall of the push bar (411), a push bar (414) fixedly connected to the end of the spring (415) away from the push bar (411), and the inner wall of the positioning block (413) slidably connected to the outer wall of the push bar (414). When the electric push rod (16) returns, it will drive the rotating block (321) to move. At this time, one end of the rotating rod (222) will start to lift up along the inclined surface on the rotating block (321), causing the rotating rod (222) to rotate. At this time, the push bar (411) will be affected by the gravity of the second counterweight (412), and 411 will slide down along the outer wall of the rotating rod (222). The second counterweight (412) is lighter than the first counterweight (322). When the second counterweight (412) moves to the end away from the electric push rod (16), the rotating rod (222) on the side of the second counterweight (412) will descend, and the other end of the rotating rod (222) will lift up. The push bar (411) can only slide laterally on the outer wall of the rotating rod (222) and cannot rotate.

Because the pressure plate (426) is stuck between the push bar (414) and the push bar (411), the pressure on the contact plate (427) and the hanger (17) will increase. The bottom of the pressure plate (426) is connected to the positioning block (413) with a spring three. A triangular block is fixedly connected to the outer wall of the front push block (421). The bottom of the pressure plate (426) is fixedly connected to the card block five. The rotating bar (425) is made of flexible plastic material.
