Abstract
Description
Technical Field
[0001] This invention belongs to the field of welding technology, and more specifically, relates to a welding flux loading device. Background Technology
[0002] Traditional welding methods mainly employ electric welding and gas welding. Shielded metal arc welding (SMAW) requires a welding power source capable of outputting over kilowatts and a heavy welding machine. To address the needs of field maintenance and emergency welding, portable welding electrodes have emerged on the market. Portable welding electrodes consist of a sleeve, an ignition cap, a paper tube containing the flux (the flux tube), and a plug. The flux tube is the most crucial component; it is combustible and leaves minimal residue. The outside of the flux tube is wrapped with transparent tape to provide strength and facilitate the loading of the welding flux.
[0003] In the existing technology, before the welding flux is filled into the flux tube, one end of the flux tube needs to be sealed with a plug, and then the welding flux is filled from the other end of the flux tube. The welding flux is added into the flux tube in multiple times. After each addition of welding flux, it needs to be manually tamped with a metal rod. This process is repeated until the tube is full, so as to ensure that the flux tube filled with welding flux has a certain strength and hardness. The process of filling welding flux is all done manually, which is labor-intensive and has low work efficiency. Summary of the Invention
[0004] This invention provides a welding flux loading device that can drive a compaction column to press down and compact the welding flux in the flux tube by repeatedly switching the electromagnet on and off, thereby achieving automated compaction of the welding flux in the flux tube and improving work efficiency.
[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A welding flux loading device is provided, comprising a chassis, a compaction column, a return spring, an electromagnetic cap, and an electromagnet. The chassis supports the flux tube, and an upwardly extending column is connected to the top surface of the chassis. The compaction column is slidably connected to the column via a sliding sleeve slidably fitted around its outer periphery. The main shaft of the compaction column is parallel to the main shaft of the column and located above the flux tube. The return spring is fitted around the outer periphery of the column, with its upper end abutting against the sliding sleeve, and is used to elastically push the sliding sleeve and the compaction column upwards. The electromagnetic cap is fitted at the lower end of the compaction column. The electromagnet is connected to the top surface of the chassis and is used to attract the electromagnetic cap. When the electromagnet is energized, it attracts the electromagnetic cap and moves the compaction column downwards into the flux tube to compact the welding flux inside. When the electromagnet is de-energized, the return spring elastically pushes the sliding sleeve and the compaction column upwards to reset.
[0006] In one possible implementation, at least two arc-shaped plates for clamping the medicine tube are slidably connected radially on the top surface of the chassis. The outer side of the arc-shaped plates is connected to the chassis by an elastic member extending radially along the chassis. The elastic member elastically presses against the arc-shaped plates to hug the outer periphery of the medicine tube.
[0007] In one possible implementation, the tamping column has an upward-opening receiving cavity, and a receiving tube is provided in the receiving cavity, which is coaxially arranged with the tamping column. The upper end of the receiving tube protrudes upward from the tamping column and the lower end is connected to the bottom wall of the receiving cavity. There is a discharge gap between the receiving tube and the inner wall of the receiving cavity for the welding flux to pass through. The peripheral wall of the tamping column is provided with a discharge hole that communicates with the receiving cavity and is used to release welding flux into the discharge tube.
[0008] In some embodiments, a striking member capable of vertically swinging is rotatably connected inside the receiving tube. The striking member is used to strike the inner wall of the receiving tube to discharge the flux in the discharge gap from the discharge hole.
[0009] In some embodiments, the striking element is rotatably connected to the receiving tube via a horizontally extending shaft. A first torsion spring is sleeved on the shaft to drive the shaft to rotate so that the striking element strikes the inner wall of the receiving tube. One end of the first torsion spring is connected to the striking element and the other end is connected to the receiving tube. The electromagnetic cap is slidably connected to the tamping column along the axial direction. The electromagnetic cap is provided with a toggle element that extends upward through the bottom wall of the tamping column. The toggle element is located between the striking element and the inner wall of the receiving tube. When the electromagnet is energized, the electromagnetic cap can move downward relative to the tamping column under the attraction of the electromagnet and cause the toggle element to toggle the striking element so that the upper end of the striking element swings toward the central axis of the receiving tube. When the electromagnetic cap contacts the welding flux, the tamping column can move downward relative to the electromagnetic cap due to inertia and cause the toggle element to release the striking element to strike the inner wall of the receiving tube.
[0010] In some embodiments, the upper end of the receiving tube is provided with a sealing cap for sealing the upper port of the receiving tube, and the upper end of the tamping column is connected to a hopper communicating with the discharge gap, and the hopper gradually converges towards the central axis from top to bottom.
[0011] In some embodiments, a disturbance component located inside the hopper is rotatably connected to the sealing cap via a swing shaft. The swing shaft is coaxial with the hopper and can drive the disturbance component to swing horizontally to disturb the welding flux inside the hopper.
[0012] In some embodiments, the pendulum shaft passes downward through the sealing cap, and the lower end of the pendulum shaft is connected to a force-applying rod extending radially along the pendulum shaft. The striking component includes a mating part that contacts and engages with the actuating component and a striking part connected to the upper end of the mating part. The mating part is rotatably connected to the rotating shaft, and the striking part is located at one end near the rotating shaft. The end face of the striking part near the end of the pendulum shaft can press against the peripheral wall of the force-applying rod to make the force-applying rod swing horizontally around the pendulum shaft.
[0013] In some embodiments, a second torsion spring is sleeved on the outer periphery of the swing shaft. One end of the second torsion spring is connected to the sealing cap and the other end is connected to the swing shaft. The second torsion spring is used to drive the force rod to press against the end face of the striking part.
[0014] In one possible implementation, the upper end of the column is positioned above the return spring.
[0015] Compared with the prior art, the flux filling device provided in this embodiment repeatedly turns the electromagnet on and off, and adds an appropriate amount of flux into the flux tube when the electromagnet is de-energized. The electromagnetic cap, under the intermittent attraction of the electromagnet, repeatedly drives the tamping column to press down and tamp the flux in the flux tube until the flux tube is full and compacted. This realizes the automated compaction of the flux in the flux tube and improves work efficiency. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the invention, "a number" means two or more, unless otherwise explicitly specified.
[0027] Please see Figures 1 to 6 The welding flux loading device provided by the present invention will now be described. The welding flux loading device includes a base 10, a tamping column 20, a return spring 30, an electromagnetic cap 40, and an electromagnet 50. The base 10 supports the flux tube 1, and an upwardly extending column 11 is connected to the top surface of the base 10. The tamping column 20 is slidably connected to the column 11 via a sliding sleeve 25 that is slidably fitted around the outer periphery of the column 11. The main axis of the tamping column 20 is parallel to the main axis of the column 11 and is located above the flux tube 1. The return spring 30 is fitted around the outer periphery of the column 11, and its upper end is connected to the sliding sleeve. 25 abuts against the upper elastically pushing the sliding sleeve 25 and the tamping column 20; the electromagnetic cap 40 is sleeved on the lower end of the tamping column 20; the electromagnet 50 is connected to the top surface of the chassis 10 and is used to attract the electromagnetic cap 40; wherein, when the electromagnet 50 is energized, the electromagnet 50 can attract the electromagnetic cap 40 and drive the tamping column 20 to move down into the chemical tube 1 to tamp the welding flux in the chemical tube 1; when the electromagnet 50 is de-energized, the return spring 30 pushes the sliding sleeve 25 and the tamping column 20 upward to reset.
[0028] The tamping column 20, the return spring 30, and the upright column 11 are all made of copper or a material that does not attract the electromagnet 50. The electromagnet 50 is embedded in the middle of the chassis 10 and is coaxially arranged with the chassis 10.
[0029] This application provides a welding flux filling device. In actual use, the end of the flux tube 1 with the plug is placed on the chassis 10 and directly below the tamping column 20. Holding the flux tube 1, the electromagnet 50 is energized. Under the attraction of the electromagnet 50, the electromagnetic cap 40 drives the tamping column 20 to press down and compact the welding flux in the flux tube 1. When the electromagnet 50 is de-energized, the return spring 30 drives the tamping column 20 to move up to the initial position and adds a certain amount of welding flux into the flux tube 1. Then, the electromagnet 50 is energized and de-energized again, and this process is repeated until the flux tube 1 is full and compacted (it is not necessary to add welding flux every time the electromagnet 50 is de-energized; it depends on the actual situation). By repeatedly driving the tamping column 20 under the intermittent attraction of the electromagnet 50, the electromagnetic cap 40 not only ensures that the flux-filled flux tube 1 has a certain strength and hardness, but also realizes the automated compaction of the welding flux in the flux tube 1, improving work efficiency.
[0030] Compared with the prior art, the flux filling device provided in this embodiment repeatedly turns the electromagnet 50 on and off, and adds a suitable amount of flux into the flux tube 1 when the electromagnet 50 is de-energized. Under the intermittent attraction of the electromagnet 50, the electromagnetic cap 40 repeatedly drives the tamping column 20 to press down and tamp the flux in the flux tube 1 until the flux in the flux tube 1 is full and compacted. This realizes the automated compaction of the flux in the flux tube 1 and improves the work efficiency.
[0031] In one possible implementation, the aforementioned chassis 10 adopts the following... Figure 1 The structure shown is described in the following document. Figure 1 At least two arc-shaped plates 60 for clamping the medicine tube 1 are slidably connected in the radial direction on the top surface of the chassis 10. The outer side of the arc-shaped plate 60 is connected to the chassis 10 through an elastic member 61 extending radially along the chassis 10. The elastic member 61 elastically presses the arc-shaped plate 60 to hug the outer periphery of the medicine tube 1.
[0032] Specifically, multiple curved plates 60 can automatically clamp the medicine tube 1 under the elastic push of their respective corresponding elastic elements 61, eliminating the need for manual hand support of the medicine tube 1 and improving practicality.
[0033] The side wall of the arc plate 60 near the medicine tube 1 is a concave arc surface, which is used to fit and conform to the outer peripheral wall of the medicine tube 1. Under the push of the elastic member 61, the arc plate 60 elastically abuts against the outer peripheral wall of the medicine tube 1, avoiding damage to the medicine tube 1. It can also be used for medicine tubes 1 of different diameters, further improving its practicality.
[0034] Furthermore, the chassis 10 is provided with an upward-opening groove that extends radially along the chassis 10, the arc plate 60 is slidably connected in the groove, and the elastic member 61 is located in the groove.
[0035] In one possible implementation, the aforementioned rammed column 20 adopts the following... Figure 1 and Figure 3 The structure shown is described in the following document. Figure 1 and Figure 3 The tamping column 20 has an upward-opening receiving cavity. Inside the receiving cavity, there is a receiving tube 23 coaxially arranged with the tamping column 20. The upper end of the receiving tube 23 protrudes upward from the tamping column 20, and the lower end is connected to the bottom wall of the receiving cavity. There is a discharge gap 22 between the receiving tube 23 and the inner wall of the receiving cavity for the welding flux to pass through. The peripheral wall of the tamping column 20 is provided with a discharge hole 21 that communicates with the receiving cavity and is used to release welding flux into the flux tube 1.
[0036] Specifically, welding flux can be added to the discharge gap 22 in advance. During the downward compaction and vibration of the compaction column 20, the welding flux in the discharge gap 22 is intermittently discharged from the discharge hole 21 (because the opening of the discharge hole 21 is small, a certain amount of welding flux can only be discharged under the vibration and impact of the compaction column 20). This allows the compaction column 20 to both compact the welding flux in the flux tube 1 and add flux to the flux tube 1, thus improving its practicality.
[0037] In some embodiments, see Figure 3 and Figure 4 The receiving tube 23 is rotatably connected to a striking element 70 that can swing vertically. The striking element 70 is used to strike the inner wall of the receiving tube 23 so that the welding flux in the discharge gap 22 is discharged from the discharge hole 21.
[0038] Specifically, the striking element 70 is made of copper or a material that does not attract the electromagnet 50. The receiving tube 23 is used to install the striking element 70, and the discharge gap 22 is used to store the welding flux, thus separating the welding flux from the striking element 70 and preventing the welding flux from interfering with the swinging striking effect of the striking element 70. Furthermore, the upper end of the receiving tube 23 is higher than the upper end of the tamping column 20 to prevent the welding flux from entering the receiving tube 23.
[0039] During use, welding flux is added to the discharge gap 22 in advance. During the downward compaction and vibration of the tamping column 20, the welding flux in the receiving cavity is intermittently discharged from the discharge hole 21. When the tamping column 20 vibrates, the striking part 70 swings vertically to strike the inner wall of the receiving tube 23, so as to facilitate the vibration discharge of the welding flux in the discharge gap 22, avoid the accumulation of welding flux in the discharge gap 22, and improve practicality.
[0040] In some embodiments, see Figure 3 and Figure 4The striking element 70 is rotatably connected to the receiving tube 23 via a horizontally extending rotating shaft 721. A first torsion spring 722 is sleeved on the rotating shaft 721 to drive the rotating shaft 721 to rotate so that the striking element 70 strikes the inner wall of the receiving tube 23. One end of the first torsion spring 722 is connected to the striking element 70, and the other end is connected to the receiving tube 23. The electromagnetic cap 40 is axially slidably connected to the tamping column 20. The electromagnetic cap 40 is provided with a toggle element 41 that extends upward through the bottom wall of the tamping column 20. The component 41 is located between the striking component 70 and the inner wall of the receiving tube 23. When the electromagnet 50 is energized, the electromagnetic cap 40 can move downward relative to the tamping column 20 under the attraction of the electromagnet 50, and the actuating component 41 can move the striking component 70 so that the upper end of the striking component 70 swings towards the central axis of the receiving tube 23. When the electromagnetic cap 40 comes into contact with the welding flux, the tamping column 20 can move downward relative to the electromagnetic cap 40 by inertia, and the actuating component 41 can release the striking component 70 to strike the inner wall of the receiving tube 23.
[0041] Specifically, the actuating element 41 is connected to the inner bottom wall of the electromagnetic cap 40 and slides in a vertical direction with the tamping column 20. The first torsion spring 722 is made of copper or a material that does not attract the electromagnet 50. When the electromagnet 50 is de-energized, the upper end of the striking element 70 abuts against the inner wall of the receiving tube 23, the actuating element 41 is positioned between the striking element 70 and the inner wall of the receiving tube 23, and the electromagnetic cap 40 slides upward on the tamping column 20 to its upper limit position.
[0042] When the electromagnet 50 is energized, the electromagnet 50 attracts the electromagnetic cap 40 and moves it downward. The electromagnetic cap 40 drives the tamping column 20 to move downward and moves downward relative to the tamping column 20. When the electromagnetic cap 40 moves downward relative to the tamping column 20, the actuating element 41 actuates the striking element 70, causing its upper end to swing vertically towards the central axis of the receiving tube 23. At this time, the first torsion spring 722 has a certain torque. After the electromagnetic cap 40 contacts the welding flux in the flux tube 1, the downward speed decreases. Under the action of inertial force, the tamping column 20 continues to move downward relative to the electromagnetic cap 40, that is, the actuating element 41 moves upward instantaneously. At this time, the striking element 70 loses its restraint. The first torsion spring 722 drives the striking element 70 to swing vertically to the upper end to strike the inner wall of the receiving tube 23, thereby releasing the welding flux in the discharge gap 22 from the discharge hole 21 into the flux tube 1, avoiding the accumulation of welding flux in the discharge gap 22, and realizing the synchronous operation of welding flux tamping and continuous welding flux addition.
[0043] Furthermore, the toggle member 41 is in the shape of a gate frame, and the lower end of the striking member 70 can swing into the toggle member 41.
[0044] In some embodiments, see Figure 1 and Figure 3 The upper end of the receiving tube 23 is provided with a sealing cap 24 for sealing the upper port of the receiving tube 23. The upper end of the compaction column 20 is connected to a hopper 80 that communicates with the discharge gap 22. The hopper 80 gradually converges towards the central axis from top to bottom.
[0045] Specifically, the sealing cap 24 is used to seal the upper port of the receiving tube 23. The sealing cap 24 and the receiving tube 23 are connected by a plug-in connection, which prevents welding flux from entering the receiving tube 23 from the upper port, thus ensuring the cleanliness of the inside of the receiving tube 23. The setting of the hopper 80 indirectly increases the upper opening of the tamping column 20, making it easier for workers to add welding flux into the discharge gap 22. When welding flux needs to be added, simply pour the welding flux into the hopper 80, and the welding flux will enter the discharge gap 22 from the lower port of the hopper 80, reducing the difficulty of adding flux.
[0046] In some embodiments, see Figure 1 , Figure 3 and Figure 6 The sealing cap 24 is rotatably connected to a disturbance component 90 located inside the hopper 80 via a swing shaft 91. The swing shaft 91 is coaxially arranged with the hopper 80, and the swing shaft 91 can drive the disturbance component 90 to swing horizontally to disturb the welding flux inside the hopper 80.
[0047] Specifically, the disturbance member 90 extends between the hopper 80 and the receiving tube 23, and can agitate the welding flux in the hopper 80, so that the welding flux in the hopper 80 is in a flowing state, and the welding flux is prevented from accumulating in the hopper 80.
[0048] Furthermore, the disturbance member 90 includes an extension rod connected to the upper end of the swing shaft 91 and extending radially along the swing shaft 91, and a disturbance rod connected to the extension end of the extension rod and extending downward to the hopper 80 and the receiving tube 23. The disturbance rod is used to disturb the welding flux in the hopper 80.
[0049] In some embodiments, see Figure 1 , Figure 3 , Figure 4 and Figure 6 The swing shaft 91 is disposed downward through the sealing cap 24. The lower end of the swing shaft 91 is connected to a force rod 93 extending radially along the swing shaft 91. The striking member 70 includes a mating part 72 that contacts and engages with the actuating member 41 and a striking part 71 connected to the upper end of the mating part 72. The mating part 72 is rotatably connected to the rotating shaft 721. The striking part 71 is disposed at one end near the rotating shaft 721. The end face of the striking part 71 near the shaft end of the swing shaft 91 can press against the peripheral wall of the force rod 93 to make the force rod 93 swing horizontally around the swing shaft 91.
[0050] Specifically, the striking part 71 and the mating part 72 are offset from each other in the axial direction of the rotating shaft 721. The striking part 71 can swing vertically to one side of the swing shaft 91 to avoid interference with the swing shaft 91 during the swing process, thereby facilitating the striking part 70 to move the force application rod 93.
[0051] Before energizing the electromagnet 50, rotate the disturbance component 90 until the force rod 93 contacts the upper end of the swing shaft 91. Then, energize the electromagnet 50. The electromagnet 50 attracts the electromagnetic cap 40 and moves downward. The electromagnetic cap 40 drives the tamping column 20 downward and moves downward relative to the tamping column 20. When the electromagnetic cap 40 moves downward relative to the tamping column 20, the actuating component 41 actuates the mating part 72, causing the upper end of the striking part 71 to swing vertically towards the central axis of the receiving tube 23. The end face of the striking part 71 near the shaft end of the swing shaft 91 can press against the peripheral wall of the force rod 93, causing the force rod 93 to swing horizontally around the swing shaft 91. The disturbance component 90 swings horizontally under the drive of the swing shaft 91. At this time, the first torsion spring 722 has a certain torque. After the electromagnetic cap 40 comes into contact with the welding flux in the medicine tube 1, the downward speed decreases. Under the action of inertial force, the tamping column 20 continues to move downward relative to the electromagnetic cap 40, that is, the actuating part 41 moves upward, so that the mating part 72 is no longer restricted. The first torsion spring 722 drives the striking part 70 to swing vertically to the upper end of the striking part 71 and strike the inner wall of the receiving tube 23. This achieves the tamping of the welding flux in the medicine tube 1, as well as the disturbance of the material in the hopper 80 and the vibration disturbance of the material in the discharge gap 22. That is, when the electromagnet 50 is energized, the above-mentioned multiple effects are achieved, which improves the practicality.
[0052] In some embodiments, see Figure 3 A second torsion spring 92 is sleeved on the outer periphery of the swing shaft 91. One end of the second torsion spring 92 is connected to the sealing cap 24 and the other end is connected to the swing shaft 91. The second torsion spring 92 is used to drive the force rod 93 to press against the end face of the striking part 71.
[0053] Specifically, the second torsion spring 92 is made of copper or a material that does not attract the electromagnet 50. When the electromagnet 50 is energized, it attracts the electromagnetic cap 40, causing it to move downwards. The electromagnetic cap 40 then moves the tamping column 20 downwards relative to the tamping column 20. As the electromagnetic cap 40 moves downwards relative to the tamping column 20, the actuating element 41 actuates the mating part 72, causing the upper end of the striking part 71 to swing vertically towards the central axis of the receiving tube 23. The striking part 71 also actuates the force application rod 93, causing the disturbance element 90 to swing horizontally. At this time, both the first torsion spring 722 and the second torsion spring 92 have a certain torque. After the electromagnetic cap 40 contacts the welding flux in the flux tube 1, its downward speed decreases, and the tamping column 20... Under the action of inertial force, it continues to move downward relative to the electromagnetic cap 40, that is, the actuating member 41 moves upward. The first torsion spring 722 drives the striking member 70 to swing vertically to the upper end to strike the inner wall of the receiving tube 23. The second torsion spring 92 causes the swing shaft 91 to reset and rotate, that is, it drives the force rod 93 to always press against the end face of the striking part 71 near the shaft end of the swing shaft 91. The torque of the second torsion spring 92 can also help the striking part 71 swing back to strike the receiving tube 23. At the same time, the reset of the force rod 93 facilitates the next use of the electromagnet 50, avoids the situation of manually resetting the disturbing member 90, and improves practicality.
[0054] In one possible implementation, the aforementioned column 11 adopts the following... Figure 1 The structure shown is described in the following document. Figure 1 The upper end of the column 11 is positioned higher than the return spring 30.
[0055] Specifically, the upper end of the column 11 is much higher than the upper end of the return spring 30. The tamping column 20 slides on the column 11 through a sliding sleeve 25 fitted around its outer periphery. The upper end of the return spring 30 contacts the sliding sleeve 25, meaning the return spring 30 can be separated from the sliding sleeve 25. When placing or removing the medicine tube 1 onto the chassis 10, the tamping column 20 can be moved upwards until the medicine tube 1 can be removed, avoiding interference between the tamping column 20 and the medicine tube 1 during this process. Simultaneously, when the return spring 30 drives the tamping column 20 to reset, considering the upward inertial force of the tamping column 20, the longer column 11 can prevent the sliding sleeve 25 from separating from the column 11 during the reset of the return spring 30, improving practicality.
[0056] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

The upper end of the receiving tube protrudes upward from the tamping column and the lower end is connected to the bottom wall of the receiving cavity. There is a discharge gap between the receiving tube and the inner wall of the receiving cavity for the welding flux to pass through. The peripheral wall of the tamping column is provided with a discharge hole that communicates with the receiving cavity and is used to release the welding flux into the flux tube. The receiving tube is rotatably connected to a striking member capable of vertical swinging. The striking member is used to strike the inner wall of the receiving tube so that the welding flux in the discharge gap is discharged from the discharge hole. The striking component is rotatably connected to the receiving tube via a horizontally extending rotating shaft. A first torsion spring is sleeved on the rotating shaft to drive the rotating shaft to rotate so that the striking component strikes the inner wall of the receiving tube. One end of the first torsion spring is connected to the striking component, and the other end is connected to the receiving tube. The electromagnetic cap is slidably connected to the tamping column along the axial direction. The electromagnetic cap is provided with a toggle member that extends upward through the bottom wall of the tamping column. The toggle member is located between the striking component and the inner wall of the receiving tube. When the electromagnet is energized, the electromagnetic cap can move downward relative to the tamping column under the attraction of the electromagnet, and the toggle member can move the striking component so that the upper end of the striking component swings toward the central axis of the receiving tube. When the electromagnetic cap contacts the welding flux, the tamping column can move downward relative to the electromagnetic cap due to inertia, and the toggle member can release the striking component to strike the inner wall of the receiving tube. The upper end of the receiving tube is provided with a sealing cap for sealing the upper port of the receiving tube, and the upper end of the tamping column is connected to a hopper that communicates with the material discharge gap. The hopper gradually converges towards the central axis from top to bottom. The sealing cap is rotatably connected to a disturbance component located inside the hopper via a swing shaft. The swing shaft is coaxial with the hopper and can drive the disturbance component to swing horizontally to disturb the welding flux inside the hopper. The swing shaft passes downward through the sealing cap. The lower end of the swing shaft is connected to a force-applying rod extending radially along the swing shaft. The striking component includes a mating part that contacts and engages with the actuating component and a striking part connected to the upper end of the mating part. The mating part is rotatably connected to the rotating shaft. The striking part is located at one end near the rotating shaft. The end face of the striking part near the end of the swing shaft can press against the peripheral wall of the force-applying rod to make the force-applying rod swing horizontally around the swing shaft. A second torsion spring is sleeved on the outer periphery of the swing shaft. One end of the second torsion spring is connected to the sealing cap and the other end is connected to the swing shaft. The second torsion spring is used to drive the force rod to press against the end face of the striking part.
