Description

Technical Field

[0001] This invention relates to the field of metal laser cutting equipment technology, specifically a laser cutting machine for producing baffles for micro-tillers. Background Technology

[0002] Laser cutting utilizes the energy released when a laser beam irradiates the surface of a workpiece to melt and evaporate it, achieving the purpose of cutting and carving. In the field of metal cutting machinery, laser cutting machines have become the mainstream production machinery. They offer not only high processing precision but also high production efficiency. Currently, most laser cutting machines on the market consist of a longitudinal movement assembly, a transverse movement assembly, a metal support component, a laser gun assembly, an auxiliary air supply system, and a control unit. During production, the laser gun assembly cuts the metal on the metal support component by moving longitudinally and laterally. For example, the baffles of mini-tillers are mostly made of thin stainless steel sheets, which are laser-cut and then bent using a rolling mill.

[0003] In some cases, when the laser cutting nozzle first contacts the outer wall of the thin metal sheet, the metal jet is reflected due to the material of the thin metal sheet. This causes sparks to fly when the nozzle first contacts the surface of the metal sheet. These sparks then fall onto the outer surface of the metal, and the high-temperature spark particles will scorch the outer wall of the stainless steel, causing the stainless steel to develop spots due to heat. To address these issues, the following solutions are proposed. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a laser cutting machine for producing baffles for micro-tillers, including a machine tool, an electric sliding frame slidably connected to the top of the machine tool, an electric sliding frame slidably connected to the inner wall of the electric sliding frame 1, an electric frame fixedly connected to the bottom of the electric sliding frame 2, a moving rod fixedly connected to the output end of the electric frame, a fixed rod fixedly connected to the bottom of the moving rod, and a laser nozzle fixedly connected to the bottom of the fixed rod, and further comprising:

[0005] The shielding mechanism is fixedly connected to the bottom of the electric frame. When the electric frame forces the moving rod to move downward, the shielding mechanism will deform.

[0006] The pressure-bearing mechanism is fixedly connected to the side wall of the shielding mechanism. When the shielding mechanism deforms, the pressure-bearing mechanism will shield the cutting outer wall and block the flying metal particles.

[0007] The pressure mechanism is rotatably connected to the inner wall of the shielding mechanism to receive metal particles generated by the laser nozzle.

[0008] Before using the equipment, the metal sheet to be cut is placed on top of the machine tool. Then, the electric sliding frame one and electric sliding frame two drive the laser nozzle to move, and the equipment completes the basic cutting process under the cutting of the laser nozzle.

[0009] Preferably, the shielding mechanism includes:

[0010] The push component is fixedly connected to the bottom of the electric frame via a support member;

[0011] The support includes a track fixedly connected to the bottom of the electric frame, a sliding block slidably connected to the inner wall of the track, a folding frame rotatably connected to the bottom of the sliding block, and a round rod fixedly connected to the side wall of the moving rod.

[0012] The pressure assembly is connected to a sliding square ring on the outer wall of the fixed rod. A second track is fixedly connected to the side wall of the sliding square ring, and a second sliding block is slidably connected to the inner wall of the second track.

[0013] When the electric frame moves the moving rod downwards, the distance between the electric frame and the moving rod increases. At this time, the extended folding frame will force the sliding square ring to slide downwards along the outer wall of the fixed rod and block the outer wall of the cutting position.

[0014] Preferably, the pressure-bearing mechanism includes:

[0015] The rotating assembly is rotatably connected to the inner wall of track two via a limiting component;

[0016] The limiting component includes a rotating rod rotatably connected to the inner wall of track two, and an inclined block is fixedly connected to the side wall of the rotating rod;

[0017] An auxiliary component is fixedly connected to the inner wall of the rotating component.

[0018] During the downward movement of the sliding square ring, the auxiliary component will contact the top of the machine tool and force the rotating rod to rotate outward, so that the inclined block moves away from the outer wall of the sliding block two and contacts the restriction of the sliding block two.

[0019] Preferably, the pressure mechanism includes:

[0020] The receiving component is rotatably connected to the inner wall of the sliding square ring via a pressure-bearing component;

[0021] The pressure-bearing component includes a rotating tube rotatably connected to the inner wall of the sliding square ring, and a receiving plate is fixedly connected to the side wall of the rotating tube;

[0022] The contact component is fixedly connected to the inner wall of the sliding square ring by a limiting member;

[0023] A limiting component is fixedly connected to a blocking rod on the inner wall of the sliding square ring;

[0024] When the receiving plate rotates, it will rotate synchronously around the rotating tube, forcing the outer wall of the receiving plate to contact the outer wall of the blocking rod.

[0025] Preferably, the pressure assembly includes a round rod two fixedly connected to the side wall of the sliding block two, and the outer wall of the round rod two is rotatably connected to the inner wall of the end of the folding frame;

[0026] When the folding frame extends or retracts, it will drive the two round rods to move up and down synchronously. The force is transmitted to the sliding square ring through the rotating component, forcing the sliding square ring to slide synchronously.

[0027] Preferably, the pushing component includes a stop fixedly connected to the side wall of the fixed rod, and the folding position of the folding frame is rotatably connected to the outer wall of the round rod.

[0028] After the equipment completes the cutting of a single mini-tiller baffle, the electric frame will drive the moving rod to reset, reducing the distance between the electric frame and the moving rod. At this time, the folding frame will also retract, causing the second round rod to move upward. The upward-moving round rod will drive the sliding square ring to move upward synchronously through the second sliding block. When the sliding square ring contacts the bottom of the baffle, the sliding square ring will stop moving, and the second round rod will drive the second sliding block to continue moving upward along the inner wall of the second track. Finally, the second sliding block will be restricted by the buckle of the rotating component and stop moving.

[0029] Preferably, the rotating assembly includes a torsion spring fixedly connected to the inner wall of the rotating rod;

[0030] In this system, the torsion spring is always in a deformed state, forcing the rotating rod to drive the inclined block to rotate inward, and restricting the sliding of the sliding block 2 when the equipment is not being processed.

[0031] Preferably, the auxiliary component includes a spring 1 fixedly connected to the bottom of the sliding block 2, and a roller rotatably connected to the end of the rotating rod away from the torsion spring 1;

[0032] When the inclined block restricts the sliding block 2, the spring 1 is in an extended state and accumulates potential energy. After the inclined block releases the restriction on the sliding block 2, the spring 1 will drive the sliding block 2 to slide down along the inner wall of the track 2.

[0033] Preferably, the receiving component includes a beveled groove formed in the side wall of the receiving plate;

[0034] As the receiving plate rotates, the sputtered metal particles will be ejected outwards and fall onto the inner wall of the inclined groove.

[0035] Preferably, the contact assembly includes a torsion spring II fixedly connected to the inner wall of the rotating tube;

[0036] During use, the second torsion spring continuously generates potential energy, forcing the receiving plate to rotate around the rotating tube. When the sliding square ring moves upward, the outer wall of the receiving plate will contact the outer wall of the fixed rod, and the electric frame will scrape off the metal particles remaining on the outer wall of the receiving plate.

[0037] The present invention has the following beneficial effects:

[0038] (1) The present invention utilizes the feature of the electric frame driving the moving rod to extend and retract. A sliding square ring is provided inside the equipment. When the electric frame drives the moving rod to move downward, the distance between the electric frame and the moving rod increases and forces the folding frame to deform. The extended folding frame will drive the round rod two to move downward synchronously. At this time, the round rod two is restricted by the inclined block, which causes the pressure on the round rod two and the sliding block two to be transmitted to the outer wall of the track two through the inclined block and the rotating rod, forcing the track two and the sliding square ring to move downward synchronously. The track two will drive the sliding square ring to slide downward synchronously along the outer wall of the fixed rod. When the laser nozzle end contacts the outer wall of the metal plate, the bottom of the sliding square ring also contacts the outer wall of the metal plate. Through the application of the above components, when the laser nozzle just contacts the metal plate, the sliding square ring will wrap around the laser nozzle to prevent the splashed metal particles from causing blemishes on the outer wall of the metal plate.

[0039] (2) This invention utilizes the downward sliding characteristic of the sliding square ring to provide a pressure-bearing mechanism inside the device. As the sliding square ring moves downward, the roller will first contact the outer wall of the metal sheet. Due to the inclination angle of the rotating rod, the roller, after being pressed, will drive the rotating rod to rotate around the torsion spring. Figure 7 As shown, the rotating rod will drive the inclined block away from the outer wall of the sliding block two, thereby releasing the restriction on the sliding block two. The sliding block two and the round rod two are restricted by the folding frame and remain stationary. The spring one will release potential energy, forcing the track two to drive the sliding square ring to move upward synchronously, so that the bottom of the sliding square ring is away from the outer wall of the metal plate. Through the application of the above components, after the laser nozzle contacts the outer wall of the metal plate and the sliding square ring completes the blocking of metal sparks, the sliding square ring retracts upward under the pull of the spring one, avoiding the equipment deviation caused by the large contact area between the sliding square ring and the metal plate during the subsequent lateral movement of the laser nozzle.

[0040] (3) This invention utilizes the downward movement characteristic of the sliding square ring and sets up a pressure mechanism inside the device. During the downward movement of the sliding square ring, the torsion spring provides an inward rotational thrust to the device, so that after the sliding square ring moves to its lowest position, the torsion spring will drive the receiving plate to rotate, presenting the following... Figure 10In this state, the flying sparks come into contact with the inner wall of the sliding square ring during the movement and fall downwards. Finally, the receiving plate will catch most of the metal particles. Through the application of the above components, the flying metal particles are prevented from accumulating inside the sliding square ring, causing metal accumulation inside the sliding square ring. In the subsequent laser nozzle cutting process, the metal particles are heated and melt at the cutting edge, causing excessive burrs on the cutting edge.

[0041] (4) After the device completes the cutting of a single micro-tiller baffle, the electric frame will drive the moving rod to reset, thereby reducing the distance between the electric frame and the moving rod. At this time, the folding frame will also retract and drive the round rod two to move upward. The upward-moving round rod two drives the sliding square ring to move upward synchronously through the sliding block two. When the sliding square ring contacts the bottom of the baffle, the sliding square ring will stop moving, and the round rod two will drive the sliding block two to continue moving upward along the inner wall of the track two. Finally, the sliding block two will be restricted by the buckle of the rotating component and stop moving. Through the application of the above components, the device can adapt to long-term high-intensity operation. Attached Figure Description

[0055] 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.

[0056] Example 1, please refer to Figure 1 - Figure 5 This invention relates to a laser cutting machine for producing baffles for micro-tillers, comprising a machine tool 13, an electric sliding frame 14 slidably connected to the top of the machine tool 13, an electric sliding frame 15 slidably connected to the inner wall of the electric sliding frame 14, an electric frame 16 fixedly connected to the bottom of the electric sliding frame 15, a moving rod 17 fixedly connected to the output end of the electric frame 16, a fixed rod 18 fixedly connected to the bottom of the moving rod 17, and a laser nozzle 19 fixedly connected to the bottom of the fixed rod 18. The invention also includes:

[0057] The shielding mechanism 1 is fixedly connected to the bottom of the electric frame 16. When the electric frame 16 forces the moving rod 17 to move downward, the shielding mechanism 1 will deform.

[0058] The pressure-bearing mechanism 2 is fixedly connected to the side wall of the shielding mechanism 1. When the shielding mechanism 1 deforms, the pressure-bearing mechanism 2 will shield the cutting outer wall and block the flying metal particles.

[0059] Pressure mechanism 3 is rotatably connected to the inner wall of shielding mechanism 1, and is used to receive metal particles generated by laser nozzle 19.

[0060] Before using the equipment, the metal sheet to be cut is placed on top of the machine tool 13. Then, the electric sliding frame 14 and the electric sliding frame 2 15 drive the laser nozzle 19 to move. Under the cutting of the laser nozzle 19, the equipment completes the basic cutting process.

[0061] The shielding mechanism 1 includes:

[0062] Push component 11 is fixedly connected to the bottom of electric frame 16 via a support member;

[0063] The support includes a track 111 fixedly connected to the bottom of the electric frame 16, a sliding block 112 slidably connected to the inner wall of the track 111, a folding frame 113 rotatably connected to the bottom of the sliding block 112, and a round rod 114 fixedly connected to the side wall of the moving rod 17.

[0064] Pressure component 12 is slidably connected to a sliding square ring 121 on the outer wall of the fixed rod 18. A second track 122 is fixedly connected to the side wall of the sliding square ring 121, and a second sliding block 123 is slidably connected to the inner wall of the second track 122.

[0065] When the electric frame 16 drives the moving rod 17 to move downward, the distance between the electric frame 16 and the moving rod 17 increases. At this time, the extended folding frame 113 will force the sliding square ring 121 to slide downward along the outer wall of the fixed rod 18 and block the outer wall of the cutting position.

[0066] The pressure-bearing mechanism 2 includes:

[0067] Rotating component 21 is rotatably connected to the inner wall of track 2 122 via a limiting member;

[0068] The limiting component includes a rotating rod 211 rotatably connected to the inner wall of track 2 122, and an inclined block 213 is fixedly connected to the side wall of the rotating rod 211;

[0069] Auxiliary component 22 is fixedly connected to the inner wall of rotating component 21;

[0070] During the downward movement of the sliding square ring 121, the auxiliary component 22 will contact the top of the machine tool 13 and force the rotating rod 211 to rotate outward, so that the inclined block 213 moves away from the outer wall of the sliding block 223 and contacts the restriction of the sliding block 223.

[0071] Pressure mechanism 3 includes:

[0072] The receiving component 31 is rotatably connected to the inner wall of the sliding square ring 121 via a pressure-bearing component;

[0073] The pressure-bearing component includes a rotating tube 311 rotatably connected to the inner wall of the sliding square ring 121, and a receiving plate 312 is fixedly connected to the side wall of the rotating tube 311.

[0074] Contact component 32 is fixedly connected to the inner wall of sliding square ring 121 by a limiting member;

[0075] The limiting member is fixedly connected to the obstructing rod 321 on the inner wall of the sliding square ring 121;

[0076] When the receiving plate 312 rotates, it will rotate synchronously around the rotating tube 311, forcing the outer wall of the receiving plate 312 to contact the outer wall of the blocking rod 321.

[0077] Example 2, please refer to Figure 2 - Figure 10 The present invention is a laser cutting machine for producing baffles for micro-tillers. Based on Example 1, the pressure component 12 includes a round rod 124 fixedly connected to the side wall of the sliding block 123. The outer wall of the round rod 124 is rotatably connected to the inner wall of the end of the folding frame 113.

[0078] When the folding frame 113 extends or retracts, it will drive the round rod 124 to move up and down synchronously. The force is transmitted to the sliding square ring 121 through the rotating component 21, forcing the sliding square ring 121 to slide synchronously.

[0079] When the equipment is not in use, the electric frame 16 will drive the moving rod 17, the fixed rod 18 and the laser nozzle 19 to a retracted state, so that the laser nozzle 19 is in a retracted state. When the equipment needs to cut, the electric frame 16 will force the moving rod 17 to extend outward and be in an extended state, and force the laser nozzle 19 to contact the outer wall of the thin plate.

[0080] The pushing component 11 includes a stop 115 fixedly connected to the side wall of the fixed rod 18, and the folding position of the folding frame 113 is rotatably connected to the outer wall of the round rod 114.

[0081] After the equipment completes the cutting of a single mini-tiller baffle, the electric frame 16 will drive the moving rod 17 to reset, reducing the distance between the electric frame 16 and the moving rod 17. At this time, the folding frame 113 will also retract, causing the round rod 124 to move upward. The upward-moving round rod 124 drives the sliding square ring 121 to move upward synchronously through the sliding block 123. When the sliding square ring 121 contacts the bottom of the baffle 115, the sliding square ring 121 will stop moving, and the round rod 124 will drive the sliding block 123 to continue moving upward along the inner wall of the track 122. Finally, the sliding block 123 will be restricted by the buckle of the rotating component 21 and stop moving.

[0082] The rotating assembly 21 includes a torsion spring 212 fixedly connected to the inner wall of the rotating rod 211;

[0083] Utilizing the characteristic of the electric frame 16 driving the extension and retraction of the moving rod 17, a sliding square ring 121 is installed inside the equipment. When the electric frame 16 drives the moving rod 17 downward, the distance between the electric frame 16 and the moving rod 17 increases, forcing the folding frame 113 to deform. The extended folding frame 113 will drive the second round rod 124 to move downward synchronously. At this time, the second round rod 124 is restricted by the inclined block 213, causing the pressure on the second round rod 124 and the second sliding block 123 to be transmitted through the inclined block 213 and the rotating rod 211. The sliding ring 121 moves synchronously downwards along the outer wall of the second track 122. The second track 122 will drive the sliding ring 121 to slide synchronously downwards along the outer wall of the fixed rod 18. When the end of the laser nozzle 19 contacts the outer wall of the metal plate, the bottom of the sliding ring 121 will also contact the outer wall of the metal plate. Through the application of the above components, when the laser nozzle 19 just contacts the metal plate, the sliding ring 121 will wrap around the laser nozzle 19, preventing the splashed metal particles from causing spots on the outer wall of the metal plate.

[0084] The auxiliary component 22 includes a spring 221 fixedly connected to the bottom of the sliding block 2 123, and a roller 222 rotatably connected to the end of the rotating rod 211 away from the torsion spring 212.

[0085] Utilizing the downward sliding characteristic of the aforementioned sliding square ring 121, a pressure-bearing mechanism 2 is installed inside the equipment. As the sliding square ring 121 moves downward, the roller 222 will first contact the outer wall of the metal sheet. Influenced by the tilt angle of the rotating rod 211, the roller 222, under pressure, will drive the rotating rod 211 to rotate around the torsion spring 212. Figure 7As shown, the rotating rod 211 will drive the inclined block 213 away from the outer wall of the sliding block 123, thereby releasing the restriction on the sliding block 123. The sliding block 123 and the round rod 124 are restricted by the folding frame 113 and remain stationary. The spring 221 will release potential energy, forcing the track 122 to drive the sliding square ring 121 to move upward synchronously, so that the bottom of the sliding square ring 121 is away from the outer wall of the metal plate. Through the application of the above components, after the laser nozzle 19 contacts the outer wall of the metal plate and the sliding square ring 121 completes the blocking of metal sparks, the sliding square ring 121 retracts upward under the pull of the spring 221, so as to avoid the equipment from shifting during the subsequent lateral movement of the laser nozzle 19 because the contact surface between the sliding square ring 121 and the metal plate is large.

[0086] The receiving component 31 includes a sloping groove 313 formed in the side wall of the receiving plate 312;

[0087] When the receiving plate 312 rotates, the sputtered metal particles will be sprayed outward and fall onto the inner wall of the inclined groove 313.

[0088] After the equipment completes the cutting of a single mini-tiller baffle, the electric frame 16 will drive the moving rod 17 to reset, reducing the distance between the electric frame 16 and the moving rod 17. At this time, the folding frame 113 will also retract, driving the second round rod 124 to move upward. The upward-moving round rod 124 drives the sliding square ring 121 to move upward synchronously through the sliding block 123. When the sliding square ring 121 contacts the bottom of the baffle 115, the sliding square ring 121 will stop moving, and the round rod 124 will drive the sliding block 123 to continue moving upward along the inner wall of the second track 122. Finally, the sliding block 123 will be restricted by the buckle of the rotating component 21 and stop moving. Through the application of the above components, the equipment can adapt to long-term high-intensity operation.

[0089] Contact component 32 includes a torsion spring 322 fixedly connected to the inner wall of the rotating tube 311;

[0090] Among them, the second torsion spring 322 always generates potential energy during use, forcing the receiving plate 312 to rotate around the rotating tube 311. When the sliding square ring 121 moves upward, the outer wall of the receiving plate 312 will contact the outer wall of the fixed rod 18, and the electric frame 16 will scrape off the metal particles remaining on the outer wall of the receiving plate 312.

[0091] Taking advantage of the downward movement of the sliding square ring 121, a pressure mechanism 3 is installed inside the equipment. During the downward movement of the sliding square ring 121, the torsion spring 322 provides an inward rotating thrust to the equipment. This causes the torsion spring 322 to rotate the receiving plate 312 after the sliding square ring 121 reaches its lowest position, resulting in the following arrangement: Figure 10In this state, the flying sparks come into contact with the inner wall of the sliding square ring 121 during the movement and fall downwards. Finally, the receiving plate 312 will receive most of the metal particles. Through the application of the above components, the flying metal particles are prevented from accumulating inside the sliding square ring 121, causing metal accumulation inside the sliding square ring 121. In the subsequent laser nozzle 19 cutting process, the metal particles are heated and melt at the cutting edge, causing excessive burrs to appear at the cutting edge.

[0092] A specific application of this embodiment is as follows: Before using the equipment, the metal sheet to be cut is placed on the top of the machine tool 13. Then, the electric sliding frame 14 and the electric sliding frame 15 drive the laser nozzle 19 to move. Under the cutting of the laser nozzle 19, the equipment completes the basic cutting process.

[0093] When the equipment is not in use, the electric frame 16 will drive the moving rod 17, the fixed rod 18 and the laser nozzle 19 to a retracted state, so that the laser nozzle 19 is in a retracted state. When the equipment needs to cut, the electric frame 16 will force the moving rod 17 to extend outward and be in an extended state, and force the laser nozzle 19 to contact the outer wall of the thin plate.

[0094] Taking advantage of the aforementioned characteristic of the electric frame 16 driving the extension and retraction of the moving rod 17, a sliding square ring 121 is provided inside the equipment. When the electric frame 16 drives the moving rod 17 downward, the distance between the electric frame 16 and the moving rod 17 increases, forcing the folding frame 113 to deform. The extended folding frame 113 will drive the second round rod 124 to move downward synchronously. At this time, the second round rod 124 is restricted by the inclined block 213, causing the pressure on the second round rod 124 and the second sliding block 123 to be transmitted through the inclined block 213 and the rotating rod 211 to... The outer wall of track 122 forces track 122 and sliding square ring 121 to move downward synchronously. Track 122 will drive sliding square ring 121 to slide downward synchronously along the outer wall of fixed rod 18. When the end of laser nozzle 19 contacts the outer wall of metal plate, the bottom of sliding square ring 121 will also contact the outer wall of metal plate. Through the application of the above components, when laser nozzle 19 just contacts metal plate, sliding square ring 121 will wrap around laser nozzle 19 to prevent splashed metal particles from causing spots on the outer wall of metal plate.

[0095] Taking advantage of the downward sliding characteristic of the sliding square ring 121, a pressure-bearing mechanism 2 is provided inside the equipment. As the sliding square ring 121 moves downward, the roller 222 will first contact the outer wall of the metal sheet. Influenced by the tilt angle of the rotating rod 211, the roller 222, after being pressed, will drive the rotating rod 211 to rotate around the torsion spring 212. Figure 7As shown, the rotating rod 211 will drive the inclined block 213 away from the outer wall of the sliding block 123, thereby releasing the restriction on the sliding block 123. The sliding block 123 and the round rod 124 are restricted by the folding frame 113 and remain stationary. The spring 221 will release potential energy, forcing the track 122 to drive the sliding square ring 121 to move upward synchronously, so that the bottom of the sliding square ring 121 is away from the outer wall of the metal plate. Through the application of the above components, after the laser nozzle 19 contacts the outer wall of the metal plate and the sliding square ring 121 completes the blocking of metal sparks, the sliding square ring 121 retracts upward under the pull of the spring 221, so as to avoid the equipment from shifting during the subsequent lateral movement of the laser nozzle 19 because the contact surface between the sliding square ring 121 and the metal plate is large.

[0096] Taking advantage of the downward movement of the sliding square ring 121, a pressure mechanism 3 is installed inside the equipment. During the downward movement of the sliding square ring 121, the torsion spring 322 provides an inward rotating thrust to the equipment. This causes the torsion spring 322 to rotate the receiving plate 312 after the sliding square ring 121 reaches its lowest position, resulting in the following arrangement: Figure 10 In this state, the flying sparks come into contact with the inner wall of the sliding square ring 121 during the movement and fall downwards. Finally, the receiving plate 312 will receive most of the metal particles. Through the application of the above components, the flying metal particles are prevented from accumulating inside the sliding square ring 121, causing metal accumulation inside the sliding square ring 121. In the subsequent laser nozzle 19 cutting process, the metal particles are heated and melt at the cutting edge, causing excessive burrs to appear at the cutting edge.

[0097] After the equipment completes the cutting of a single mini-tiller baffle, the electric frame 16 will drive the moving rod 17 to reset, reducing the distance between the electric frame 16 and the moving rod 17. At this time, the folding frame 113 will also retract, driving the second round rod 124 to move upward. The upward-moving round rod 124 drives the sliding square ring 121 to move upward synchronously through the sliding block 123. When the sliding square ring 121 contacts the bottom of the baffle 115, the sliding square ring 121 will stop moving, and the round rod 124 will drive the sliding block 123 to continue moving upward along the inner wall of the second track 122. Finally, the sliding block 123 will be restricted by the buckle of the rotating component 21 and stop moving. Through the application of the above components, the equipment can adapt to long-term high-intensity operation.
