Description

Technical Field

[0001] The invention relates to the technical field of welding tooling, and in particular to a welding tooling for processing a torch tube. Background Art

[0002] The main body of the flare tube is usually made of high temperature resistant and corrosion resistant materials, such as stainless steel or special alloys, which can withstand the high temperature generated by biogas combustion and effectively resist corrosion from the external environment. The main body of the flare tube is usually formed by welding multiple sections together to ensure the integrity and stability of the flare tube.

[0003] The Chinese patent with the announcement number CN221516752U discloses a vertical welding tool for a torch barrel, including a torch barrel body and a fixed structure, wherein a flange is provided at the connection of the torch barrel body, a round hole is provided on the surface of the flange, a positioning pin is slidably inserted in the round hole, a hexagonal nut is provided on the surface of the positioning pin, a roller frame is provided at the bottom of the torch barrel body, a fixing structure and a supporting structure are provided on the surface of the roller frame, the fixing structure includes a mounting groove and a connecting clamp, a connecting clamp is fixedly connected to the surface of the roller frame, and a fixing spring and a spring rod are fixedly connected to the surface of the fixed connecting clamp. The above patent solves the problem that most torch barrels are directly mounted on the surface of the roller frame, and during the welding process, the torch barrel vibrates, and there is an unstable connection with the roller frame, causing the torch barrel to shake on the surface of the roller frame, resulting in a deviation in the welding position.

[0004] There needs to be enough oxygen inside the internal combustion torch to maintain the combustion reaction. Usually, an air inlet is opened on the torch barrel to provide the necessary oxygen, and then a mounting frame is welded at the air inlet for the subsequent installation of shutters to adjust the air volume or to install air supply devices such as blowers. In the actual implementation process of the above patent document, when the mounting frame needs to be welded at the air inlet of the torch barrel, it is necessary to manually align and position the mounting frame and the air inlet, and stabilize the mounting frame at the air inlet before welding. The whole process requires at least two workers to cooperate, one worker to align and position the mounting frame, and the other to weld. Not only does it consume more labor and increase production costs, but manual positioning may also have positioning deviations, resulting in offset of the welding position of the mounting frame, affecting the installation of subsequent components.

[0005] Therefore, the art needs a welding tool for torch tube processing to solve the above problems. Summary of the invention

[0006] The present invention provides a welding tool for processing a flare barrel, aiming to solve the problem that the welding tool in the related art cannot align and position the air inlet and the mounting frame on the flare barrel body, resulting in a large amount of labor being required when welding the mounting frame, and manual positioning is prone to deviation.

[0007] A welding tool for processing a torch barrel of the present invention comprises a track and a support frame slidably arranged on the track, the support frame is used to horizontally place the torch barrel, a mounting frame is also slidably arranged on the track, a mounting rod is vertically slidably connected to the mounting frame, the mounting rod extends in the horizontal direction and is rotatably matched with the mounting frame, the central axis of the mounting rod and the central axis of the torch barrel placed on the support frame are located in the same vertical plane, three supporting rods are evenly arranged at circumferential intervals on the mounting rod, the supporting rods are parallel to the mounting rods, and a driving assembly 1 is arranged on the mounting rod to drive the three supporting rods to move synchronously along the radial direction of the mounting rod; Two swing rods are rotatably connected to the support rod, and the rotating shafts rotatably connected to the two swing rods and the support rod extend along the radial direction of the mounting rod. The support rod is provided with a second driving component for driving the two swing rods to rotate away from each other or close to each other at the same time. The two swing rods are respectively connected with a push piece, and the push piece is slidably connected to the swing rod in a direction perpendicular to the swing rod. The swing rod is provided with a third driving component for driving the push piece to move. Driving component one drives three supporting rods to support the inside of the flare barrel, and pushes the mounting frame toward the flare barrel. When the pushing piece moves to the air inlet of the flare barrel, driving component two drives the two rocker arms to rotate away from each other. At the same time, driving component three drives the pushing piece to extend out of the air inlet of the flare barrel. When the pushing piece abuts against two right angles of the air inlet away from the mounting frame, the pushing of the mounting frame stops.

[0008] The present invention realizes automatic centering and positioning of the central axis of the installation rod and the torch tube by arranging three support rods, so that the welding tool of the present invention can be applicable to torch tubes of different diameters, thereby improving the applicability of the present invention; the present invention enables the installation frame to be framed on the two pushing members by abutting the pushing members at two right angles of the air inlet, and aligning and positioning are performed according to the positions of the two pushing members, thereby realizing the alignment and positioning of the installation frame and the air inlet. Due to the positioning of the two pushing members, the accuracy of the welding position between the installation frame and the air inlet is improved, and the two pushing members support the installation frame, and the alignment and welding processes can be completed by one worker, thereby reducing labor consumption and lowering production costs.

[0009] Preferably, a driving assembly comprises a driving member 1 and a scissor rod 1 and a scissor rod 2 hinged at a central position, a sliding sleeve is provided on the mounting rod with a mounting ring 1, a sliding sleeve is provided on the support rod with a mounting ring 2, one end of the scissor rod 1 is hinged to the mounting ring 1, the other end of the scissor rod 1 is hinged to the support rod, one end of the scissor rod 2 is hinged to the mounting rod, the other end of the scissor rod 2 is hinged to the mounting rod, and the other end of the scissor rod 2 is hinged to the mounting ring 2, and the driving member 1 is fixedly mounted on the mounting rod and drives the mounting ring 1 to move along the mounting rod.

[0010] The support rod is driven by the scissor structure formed by the scissor rods 1 and 2, thereby ensuring the stability of the driving process of the support rod. In addition, the scissor rods 1 and 2 can also support the support rod, thereby ensuring the stability of the support rod when the support rod moves relative to the flare tube.

[0011] Preferably, the driving member includes a motor and a screw, the motor is fixedly mounted on the mounting rod, one end of the screw is fixedly connected to the output end of the motor, and the other end is rotatably connected to the mounting rod, a mounting ring is threadedly connected to the screw, the motor drives the screw to rotate, and the screw drives the mounting ring to move along the mounting rod.

[0012] Preferably, drive assembly two includes a mounting block and a driving member two. The mounting block slides with the support rod along the extension direction of the support rod. A torsion spring is provided at the rotation connection between the rocker arm and the support rod. The torsion spring drives the two rocker arms to rest against both sides of the mounting block. When the pushing member moves to the air inlet of the flare tube, the driving member two drives the mounting block to move along the support rod in the direction close to the mounting frame, and the mounting block pushes the two rocker arms to rotate in the direction away from each other.

[0013] Preferably, the mounting block is elastically connected to the support rod along the extension direction of the support rod, and the driving member 2 includes a pushing block 1, which is slidably matched with the mounting block and elastically connected along the radial direction of the mounting rod. When the mounting block is not subject to external force, it is located at an end of the support rod away from the mounting frame. When the pushing block 1 moves to the air inlet of the flare tube, it moves into the air inlet relative to the mounting block. As the mounting frame approaches the flare tube, the pushing block 1 abuts against the side wall of the air inlet and, under the pushing of the side wall of the air inlet, drives the mounting block to move in the direction close to the mounting frame.

[0014] The two rocker arms are driven by the ingenious coordination of the mounting block, the push block 1 and the side wall of the air inlet. This not only eliminates the need to set up a separate driving source for the rocker arms, thereby reducing production costs, but also makes reasonable use of the characteristic that the mounting frame needs to move in the direction close to the flare barrel, thereby driving the side wall of the air inlet to push the push block 1. The design is ingenious and the structure is compact.

[0015] Preferably, an accommodating groove for accommodating a push block 1 is provided at one end of the support rod away from the mounting frame. When one end of the push block 1 away from the mounting rod is flush with one end of the mounting block away from the mounting rod, the push block 1 is located in the accommodating groove. The accommodating groove blocks the push block 1 from moving along the extension direction of the support rod. When the push block 1 moves to the air inlet of the flare tube relative to the mounting block, the push block 1 falls out of the accommodating groove.

[0016] By providing an accommodating groove, the movement of the push block 1 is restricted to prevent the push block 1 from moving due to friction with the inner wall of the flare tube during its movement along the inner wall of the flare tube toward the air inlet, causing the swing arm to open to both sides in advance and affecting the push piece on the swing arm from entering the air inlet normally.

[0017] Preferably, the pushing member includes a pushing block 2, both ends of which are respectively fixedly connected with connecting ears, a rotating column is fixedly connected between the two connecting ears, one end of the rocker arm away from its rotating axis is rotatably matched with the rotating column, and the rotating column is slidably connected to the rocker arm along a direction perpendicular to the rocker arm.

[0018] Preferably, drive component three includes spring one and guide plates symmetrically arranged on both sides of the support rod, the two guide plates are provided with guide surfaces on the sides facing away from each other, the two guide plates are straight surfaces on the sides facing the mounting rod, the rocker arm is fixedly connected with a mounting sleeve arranged perpendicular to it, the rotating column is passed through the mounting sleeve, the spring is arranged outside the rotating column and is connected between the mounting sleeve and one of the connecting ears, and avoidance grooves for accommodating the mounting sleeve are provided on both sides of the support rod, when the rocker arm drives the mounting sleeve to move toward the avoidance groove, the connecting ear close to the mounting rod is pushed by the guide surface, driving the rotating column and the pushing block 2 to move in the direction close to the mounting rod, and when the mounting sleeve is located in the avoidance groove, the connecting ear close to the mounting rod abuts against the straight surface, and the spring one is in a stretched state.

[0019] Preferably, a plurality of support frames are arranged at intervals on the track, the support frames include a support seat and rollers symmetrically arranged on the support seat, the rollers are rotatably connected to the support seat, the bottom of the support seat is rotatably connected to a walking wheel 1, and the walking wheel 1 is connected to a driving motor 1.

[0020] Preferably, the mounting frame includes a mounting base and a mounting arm arranged on the mounting base, an elongated hole is opened on the mounting arm, a mounting rod slides vertically with the elongated hole, the bottom of the mounting base is rotatably connected to two walking wheels, the two walking wheels are connected to two driving motors, and one end of the mounting rod away from the mounting frame is fixedly connected to a positioning cylinder for installing the pipeline, and the positioning cylinder is coaxially arranged with the mounting rod.

[0021] After the three support rods are supported on the inner wall of the flare tube, the installation rod is automatically aligned with the central axis of the flare tube. At this time, the pipeline is inserted into the positioning tube to achieve automatic alignment of the pipeline with the central axis of the flare tube, which is beneficial to the installation and welding of the pipeline, eliminates the process of separately centering and positioning the pipeline, and improves work efficiency.

[0022] The beneficial effects of the present invention are as follows: (1) the present invention realizes automatic centering and positioning of the mounting rod and the central axis of the flare tube by setting three support rods, so that the welding tool of the present invention can be applied to flare tubes of different diameters, thereby improving the applicability of the present invention; (2) The present invention places the push members against two right angles of the air inlet so that the installation frame can be framed on the two push members, and aligns and positions the installation frame with the air inlet according to the positions of the two push members. The positioning of the two push members improves the accuracy of the welding position between the installation frame and the air inlet, and the two push members support the installation frame. The alignment and welding process can be completed by one worker, which reduces labor consumption and reduces production costs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0032] like Figures 1 to 7 As shown, a welding tool for processing a torch barrel of the present invention comprises a track 1 and a support frame 2 slidably arranged on the track 1, and the support frame 2 is used to horizontally place the torch barrel 3. The extension direction of the track 1 is defined as the left-right direction, and a plurality of support frames 2 are arranged at intervals along the left-right direction. The support frame 2 comprises a support seat 21 and rollers 22 symmetrically arranged on the support seat 21 in the front and rear directions, the rollers 22 are rotatably connected to the support seat 21, and the rollers 22 are used to support the torch barrel 3. The bottom of the support seat 21 is rotatably connected to a walking wheel 1 (not shown in the figure), and the walking wheel 1 is connected to a driving motor 1 (not shown in the figure). The driving motor 1 drives the walking wheel 1 to rotate, thereby driving the corresponding support seat 21 to move left and right, which can meet the alignment work when welding between multiple sections of the torch barrel 3.

[0033] A mounting frame 4 is also slidably arranged on the track 1. The mounting frame 4 includes a mounting seat 41 and a mounting arm 42 fixedly connected to the mounting seat 41. The mounting arm 42 is provided with a long hole 43. A mounting rod 5 is vertically slidably connected in the long hole 43. The mounting rod 5 extends in the left and right directions and rotates with the long hole 43. The outer periphery of the mounting rod 5 extends with a retaining edge 51 located on the left and right sides of the mounting arm 42, and the retaining edge 51 fits the mounting arm 42. The bottom of the mounting seat 41 is rotatably connected to a running wheel 2 (not shown in the figure), and the running wheel 2 is connected to a driving motor 2 (not shown in the figure). The driving motor 2 drives the running wheel 2 to rotate, thereby driving the mounting seat 41 to move left and right, so that the mounting rod 5 can extend into or out of the torch tube 3.

[0034] The central axis of the mounting rod 5 is located in the same vertical plane as the central axis of the flare barrel 3 placed on the support frame 2. Three support rods 6 are evenly spaced around the mounting rod 5. In order to clearly show the cooperation between the support rods 6 and the mounting rod 5, only one of the support rods 6 is shown in the figure. The three support rods 6 are parallel to the mounting rod 5, and the mounting rod 5 is provided with a driving component 1 that drives the three support rods 6 to move synchronously along the radial direction of the mounting rod 5.

[0035] like Figures 3 to 5As shown, the support rod 6 is rotatably connected to two swing rods 7 on one side away from the mounting rod 5, and the rotating shafts of the two swing rods 7 and the support rod 6 are rotatably connected to extend along the radial direction of the mounting rod 5. The support rod 6 is provided with a second driving component for driving the two swing rods 7 to rotate away from each other or toward each other at the same time. The two swing rods 7 are respectively connected to a push piece 71, and the push piece 71 is slidably connected to the swing rod 7 in a direction perpendicular to the swing rod 7, and the swing rod 7 is provided with a third driving component for driving the push piece 71 to move.

[0036] like Figure 1 and Figure 2 As shown, the flare barrel 3 is provided with three air inlets 31 along the circumferential direction. When it is necessary to weld the mounting frame 32 at the air inlets 31, the mounting frame 4 is controlled to move toward the flare barrel 3 so that a part of the mounting rod 5 enters into the flare barrel 3. Then, the mounting rod 5 is rotated so that the positions of the three support rods 6 on the mounting rod 5 roughly correspond to the three air inlets 31 on the flare barrel 3. Then, the driving assembly is controlled to drive the three support rods 6 to move synchronously in a direction away from the mounting rod 5 until the three support rods 6 are supported inside the flare barrel 3.

[0037] Since the mounting rod 5 is vertically slidably arranged in the long hole 43, after two of the support rods 6 contact the inner wall of the flare tube 3, the mounting rod 5 will be pushed upward until all three support rods 6 are against the inner wall of the flare tube 3. At this time, the central axis of the mounting rod 5 overlaps with the central axis of the flare tube 3, realizing automatic centering and positioning of the mounting rod 5, so that the welding tooling of the present invention can be applied to flare tubes 3 of different diameters, thereby improving the applicability of the present invention.

[0038] After that, the mounting frame 4 continues to be driven in the direction of the torch tube 3. The mounting frame 4 drives the support rod 6 to move along the inner wall of the torch tube 3. When the pushing piece 71 moves to the air inlet 31 of the torch tube 3, the driving component 2 drives the two rocker arms 7 to rotate in the direction away from each other. At the same time, the driving component 3 drives the pushing piece 71 to extend out of the air inlet 31 of the torch tube 3. When the pushing piece 71 follows the movement of the rocker arm 7 and contacts the side wall of the air inlet 31, it will drive the mounting rod 5 to rotate under the drive of the rocker arm 7 and the pushing of the side wall of the air inlet 31 until the pushing pieces 71 on the two rocker arms 7 both abut against the side wall of the air inlet 31. Since the mounting frame 4 continues to move in the direction close to the torch tube 3, the pushing piece 71 will eventually abut against the two right angles of the air inlet 31 away from the mounting frame 4. At this time, all drives are stopped to complete the positioning of the pushing piece 71 in the air inlet 31.

[0039] The mounting frame 32 is framed on the two push pieces 71, and the position of the mounting frame 32 is adjusted so that the corresponding two right angles on the mounting frame 32 fit with the two push pieces 71, thereby realizing the alignment and positioning of the mounting frame 32 and the air inlet 31, and then the mounting frame 32 and the torch tube 3 can be welded. Due to the positioning of the two push pieces 71, the accuracy of the welding position between the mounting frame 32 and the air inlet 31 is improved, and the two push pieces 71 play a supporting role for the mounting frame 32, and the alignment and welding process can be completed by one worker, which reduces labor consumption and reduces production costs.

[0040] During the production process of the flare barrel 3, it is sometimes necessary to install or weld the gas delivery pipeline in the flare barrel 3. In this embodiment, the end of the mounting rod 5 away from the mounting frame 4 is fixedly connected with a positioning cylinder 52 for installing the pipeline, and the positioning cylinder 52 is coaxially arranged with the mounting rod 5. After the three support rods 6 are supported on the inner wall of the flare barrel 3, the mounting rod 5 is automatically centered with the central axis of the flare barrel 3. At this time, the pipeline is inserted into the positioning cylinder 52, and the pipeline and the central axis of the flare barrel 3 can be automatically centered, which is conducive to the installation and welding of the pipeline, eliminating the process of separately centering and positioning the pipeline, and improving work efficiency.

[0041] like Figure 3 As shown, the driving assembly 1 includes a driving member 1 and a scissor rod 1 54 and a scissor rod 2 55 hinged at the center. A mounting ring 1 53 is provided on the sliding sleeve of the mounting rod 5, and a mounting ring 2 61 is provided on the sliding sleeve of the support rod 6. One end of the scissor rod 1 54 is hinged to the mounting ring 1 53, and the other end of the scissor rod 1 54 is hinged to the support rod 6. One end of the scissor rod 2 55 is hinged to the mounting rod 5, and the other end of the scissor rod 2 55 is hinged to the mounting ring 2 61. The driving member 1 includes a motor 56 and a lead screw 57. The motor 56 is fixedly mounted on the mounting rod 5. One end of the lead screw 57 is fixedly connected to the output end of the motor 56, and the other end is rotatably connected to the mounting rod 5. The mounting ring 1 53 is threadedly connected to the lead screw 57, and the motor 56 drives the lead screw 57 to rotate, and the lead screw 57 drives the mounting ring 1 53 to move along the extension direction of the mounting rod 5. The mounting ring 1 53 drives the scissor rod 1 54 to move, so that the scissor rod 1 54 and the scissor rod 2 55 push the support rod 6 in the direction away from the mounting rod 5 or pull the support rod 6 in the direction close to the mounting rod 5.

[0042] It is understandable that in other embodiments, the driving member 1 can also be provided with an electric push rod, the electric push rod is fixedly mounted on the mounting rod 5, the mounting ring 1 53 is fixedly connected to the driving end of the electric push rod, and the electric push rod drives the mounting ring 1 53 to move along the extension direction of the mounting rod 5.

[0043] A folding rod is hinged between one end of the support rod 6 close to the mounting frame 4 and the mounting rod 5, and the folding rod includes a connecting rod 1 58 and a connecting rod 2 59, one end of the connecting rod 1 58 is hinged to one end of the connecting rod 2 59, the other end of the connecting rod 1 58 is hinged to the corresponding support rod 6, and the other end of the connecting rod 2 59 is hinged to the mounting rod 5. The connecting rod 1 58 and the connecting rod 2 59 limit the maximum range of movement of the support rod 6. When the scissor rod 1 54 and the scissor rod 2 55 push the support rod 6 in the direction away from the mounting rod 5 until the connecting rod 1 58 and the connecting rod 2 59 are in the same straight line, the support rod 6 cannot be pushed to move further.

[0044] like Figures 4 to 6 As shown, the drive assembly 2 includes a mounting block 8 and a drive member 2. The mounting block 8 slides with the support rod 6 along the extension direction of the support rod 6, and the mounting block 8 is elastically connected to the support rod 6 through a spring 2 81. The elastic force direction of the spring 2 81 is the same as the extension direction of the support rod 6, both in the left and right direction. When the mounting block 8 is not subjected to external force, it is located at the end of the support rod 6 away from the mounting bracket 4. The drive member 2 includes a push block 1 82. The push block 1 82 slides with the mounting block 8 along the radial direction of the mounting rod 5 and is elastically connected to the mounting block 8 through a spring 3 83.

[0045] like Figure 4 and Figure 7 As shown, an accommodating groove 62 for accommodating a pushing block 82 is provided at one end of the support rod 6 away from the mounting frame 4. When the pushing block 82 is not subjected to external force, it is located at the top of the accommodating groove 62. When the end of the pushing block 82 away from the mounting rod 5 is flush with the end of the mounting block 8 away from the mounting rod 5, the pushing block 82 is located in the accommodating groove 62, and the accommodating groove 62 blocks the pushing block 82 from moving along the extension direction of the support rod 6.

[0046] A torsion spring (not shown in the figure) is provided at the rotation connection between the swing rod 7 and the support rod 6 , and the torsion spring drives the two swing rods 7 to lean against the two sides of the mounting block 8 , and the two sides of the mounting block 8 are provided with push-up inclined surfaces 84 . The three support rods 6 are supported on the inner wall of the torch tube 3, and in the process of moving to the left, the push block 82 is squeezed by the inner wall of the torch tube 3 in the receiving groove 62, and the receiving groove 62 blocks the push block 82 from moving in the left and right directions. When the push block 82 moves to the air inlet 31, under the elastic force of the spring three 83, it moves toward the air inlet 31 relative to the mounting block 8, and as the mounting frame 4 continues to approach the torch tube 3, the push block 82 will abut against the left side wall of the air inlet 31. As the mounting frame 4 continues to move, the left side wall of the air inlet 31 pushes the push block 82 to drive the mounting block 8 to move to the right. The two push inclined surfaces 84 of the mounting block 8 squeeze the two rocker arms 7 to move away from each other until the push members 71 on the two rocker arms 7 abut against the two right angles on the left side of the air inlet 31. The two rocker arms 7 are driven by the ingenious cooperation of the mounting block 8, the push block 82 and the side wall of the air inlet 31. This not only eliminates the need to set a separate driving source for the rocker arms 7, thereby reducing production costs, but also makes reasonable use of the characteristic that the mounting frame 4 needs to move toward the direction close to the flare tube 3, thereby driving the side wall of the air inlet 31 to push the push block 82. The design is ingenious and the structure is compact.

[0047] Continue to refer to Figure 4 and Figure 7 The push member 71 includes a push block 2, and the two ends of the push block 2 are respectively fixedly connected with connecting ears 72, and a rotating column 73 is fixedly connected between the two connecting ears 72. The left end of the swing rod 7 is fixedly connected with a mounting sleeve 74 arranged perpendicularly thereto, and the rotating column 73 is inserted into the mounting sleeve 74. The rotating column 73 is rotationally matched with the mounting sleeve 74, and is slidingly matched with the mounting sleeve 74 in a direction perpendicular to the swing rod 7.

[0048] The driving assembly 3 includes a spring 1 75 and guide plates 9 symmetrically arranged on both sides of the support rod 6. The two guide plates 9 are provided with guide surfaces 91 on the sides facing away from each other, and the two guide plates 9 are provided with flat surfaces 92 on the sides facing the mounting rod 5. The spring 1 75 is sleeved outside the rotating column 73 and connected between the mounting sleeve 74 and the connecting ear 72 close to the mounting rod 5. The two sides of the support rod 6 are provided with avoidance grooves 63 for accommodating the mounting sleeve 74. When the swing rod 7 drives the mounting sleeve 74 to move toward the avoidance grooves 63, the connecting ear 72 close to the mounting rod 5 is pushed by the guide surface 91, driving the rotating column 73 and the pushing block 2 to move in the direction close to the mounting rod 5. When the mounting sleeve 74 moves to the avoidance grooves 63, the connecting ear 72 close to the mounting rod 5 is located below the guide plate 9 and abuts against the flat surface 92 of the guide plate 9. At this time, the spring 1 75 is in a stretched state.

[0049] When the mounting block 8 is located at the left end of the support rod 6 and the torsion spring drives the two swing rods 7 to be located at both sides of the mounting block 8, the mounting sleeve 74 is located in the avoidance groove 63. When the mounting block 8 pushes the two swing rods 7 to move away from each other, the connecting ear 72 close to the mounting rod 5 loses the limit of the guide plate 9, and the elastic force of the spring 1 75 drives the rotating column 73 and the pushing block 2 to move away from the mounting rod 5, so that the pushing block 2 can extend out of the air inlet 31 and abut against the two right angles on the left side of the air inlet 31.
