Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of semiconductor, especially a pipeline auxiliary dismounting tool. BACKGROUND

[0002] In the semiconductor manufacturing industry, SACVD (Sub-Atmospheric Chemical Vapor Deposition) equipment is a key tool for producing high-quality thin films. Among them, Foreline as an important part of SACVD equipment, not only carries the task of gas transmission, but also is connected with the vacuum pump, forming a total channel responsible for leading out the residual gas after reaction. This structure usually contains GV valve (Gate Valve) and TV valve (Throttle Valve), which are crucial for maintaining the vacuum degree of the system and controlling the gas flow. However, with the increase of use time, a large amount of particulate matter and impurities will inevitably accumulate inside the Foreline, which may come from by-products produced during the reaction process or the invasion of the external environment. Long-term accumulation not only affects the purity and transmission efficiency of the gas, but also may cause problems such as valve wear and seal degradation, ultimately affecting the working performance and reliability of the entire SACVD equipment. Maintenance personnel regularly clean the Foreline, which is a necessary work, but this process is full of challenges. First, the Foreline structure is connected to the exhaust system at the plant end, and the overall structure is relatively bulky, which requires multiple operators to cooperate during disassembly and reinstallation, increasing labor costs and operation complexity. Secondly, since the Foreline is located between the cavity and the gas tank, with heating disc sliding table structure on both sides, the operation space is extremely limited. This not only limits the selection and use of maintenance tools, but also brings great inconvenience to the operators. In order to prevent the disassembled Foreline part from falling and causing damage or accidents, it is usually necessary to pad the remaining section with foam on the gas tank, but this cannot completely eliminate the risk. Especially when installing GV and TV valves, operators must lift the heavy Foreline to ensure that the screw holes are correctly aligned and fixed, which not only consumes a lot of physical strength, but also increases the operation time and difficulty, easily causing fatigue injury, and even has safety hazards.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

Therefore, the direction terms are used to explain and understand the present application, rather than to limit the present application. In addition, in the drawings, the structures with similar or identical structures are denoted by the same reference signs.

[0032] When performing maintenance on a SACVD apparatus, operators face challenges when disassembling valves or Foreline structures to perform cleaning work. To prevent the disassembled Foreline parts from falling, which can cause damage to the machine and endanger personnel health, operators often need to use foam pads to temporarily support the remaining segments on the gas box. However, this method cannot completely eliminate the risk, and the limited operating space increases the difficulty of the work. In addition, when reinstalling GV (gate valve) and TV (throttle valve), operators must manually lift the heavy Foreline to ensure accurate alignment and fixation with the installation screw holes. This process not only significantly increases the operating time and physical exertion of the operators, but also easily causes fatigue injuries, increasing the safety risk. Long-term physical labor also reduces work efficiency and affects the overall progress of maintenance work.

[0033] To this end, the utility model embodiment proposes a pipeline auxiliary disassembly and assembly tool, which solves the problem of difficult disassembly and assembly of the existing Foreline. The lifting assembly, horizontal moving assembly, and front and rear moving assembly are used to freely adjust the position of the clamping part, reduce the disassembly and assembly difficulty, improve the disassembly and assembly convenience, and improve the disassembly and assembly efficiency.

[0034] To solve the above-mentioned disassembly and assembly difficulty, the specific idea is as follows:

[0035] A pipeline auxiliary disassembly and assembly tool is designed to support the pipeline when disassembling the Foreline part to prevent it from falling, and to support the pipeline when installing the Foreline without the need for operators to lift it. The pipeline auxiliary disassembly and assembly tool is provided with a lifting assembly, a horizontal moving assembly, and a front and rear moving assembly. The front and rear moving assembly includes a pipeline clamping part for clamping the Foreline pipeline 7. The lifting assembly, horizontal moving assembly, and front and rear moving assembly are used to drive the pipeline clamping part to adjust the position in six degrees of freedom, i.e., up, down, left, right, front, and back, so that the screw hole for installation can be fine-tuned to center, reducing the disassembly and assembly difficulty, improving the disassembly and assembly convenience, and improving the disassembly and assembly efficiency.

[0036] In order to better understand the above technical solutions, the above technical solutions will be described in detail in conjunction with the drawings and specific embodiments of the specification.

[0037] Please refer to Figures 1-7The utility model discloses an embodiment shows a pipeline auxiliary dismounting frock, include: support piece 1, lifting assembly 2, horizontal moving assembly 3, front -back moving assembly 4, lifting assembly 2 installs on support piece 1, horizontal moving assembly 3 installs on lifting assembly 2, front -back moving assembly 4 installs on horizontal moving assembly 3, front -back moving assembly 4 includes pipeline clamping piece 42, and the front end of pipeline clamping piece 42 forms the clamping portion 421 of clamping pipeline outer periphery.

[0038] With reference to Figure 1 Specifically, support piece 1 can be a support frame or a support rod or a support sleeve, as the basic structure of the entire frock, support piece 1 provides a stable support platform capable of bearing the weight of the Foreline and other components. Front -back moving assembly 4 includes pipeline clamping piece 42, which is the part directly in contact with the pipeline, and the front end thereof is designed with clamping portion 421 capable of closely fitting the outer periphery of the pipeline, for example, in the shape of a C, clamping portion 421 clamps Foreline pipeline 7, supporting the pipeline and preventing it from sliding or loosening. Pipeline clamping piece 42 can move in the front -back direction under the action of front -back moving assembly 4, thereby adjusting the front -back position of clamping portion 421. Since front -back moving assembly 4 is installed on horizontal moving assembly 3, front -back moving assembly 4 can move in the left -right direction under the action of horizontal moving assembly 3, thereby driving pipeline clamping piece 42 on front -back moving assembly 4 to move left and right, thereby adjusting the left -right position of clamping portion 421. Further, since horizontal moving assembly 3 is installed on lifting assembly 2, horizontal moving assembly 3 can move in the up -down direction under the action of lifting assembly 2, thereby driving horizontal moving assembly 3 to move up and down, and thus pipeline clamping piece 42 also moves up and down to adjust the up -down position of clamping portion 421. It should be noted that lifting assembly 2, horizontal moving assembly 3, and front -back moving assembly 4 can be various types of structures as long as they can respectively realize movement in the six degrees of freedom of up -down, left -right, and front -back, which are not limited herein. In actual operation, the operator first places support piece 1 beside the pipeline to be disassembled, adjusts the height of clamping portion 421 by lifting assembly 2, so that clamping portion 421 reaches the desired height position; then uses horizontal moving assembly 3 to move left and right to align the interface (flange) of the pipeline, uses front -back moving assembly 4 to push pipeline clamping piece 42 into position on the pipeline, and uses clamping portion 421 to secure the pipeline, at which point the operator can release the manual lifting and rely on the frock to complete the subsequent disassembly or installation work.

[0039] Through the embodiment, the pipeline auxiliary dismounting tool is introduced to dismount the foreline, the operator no longer needs to manually lift the heavy foreline, the physical consumption and working time are greatly reduced, and the dismounting efficiency is improved; meanwhile, since the tool provides stable support and precise movement control, six degrees of freedom movement can be realized, the installation screw hole can be finely adjusted, the difficulty of manually aligning the screw hole while lifting the heavy foreline is reduced, the maintenance difficulty is reduced, the maintenance work is more efficient, and the overall production efficiency is improved

[0040] With reference to Figure 3 In an embodiment, the lifting assembly 2 comprises a lifting drive 21, a lifting screw 22 and a lifting nut 23, the lifting screw 22 is rotatably arranged in the support 1, the lifting drive 21 is connected with the lifting screw 22 to drive the rotation thereof, the lifting nut 23 is threadedly connected on the lifting screw 22, and the lifting nut 23 is connected with the transverse movement assembly 3 to drive the lifting nut 23 to move along the height direction of the support 1. Specifically, the lifting drive 21 serves as a power source for driving the rotation of the lifting screw 22, and can be a motor or other forms of power device, which provides a rotating motion by being connected with the lifting screw 22. The support 1 is internally provided with a cavity, the lifting screw 22 is rotatably arranged in the support 1 and cooperates with the lifting nut 23 to realize the lifting action through rotation. The lifting nut 23 is threadedly connected on the lifting screw 22 and connected with the transverse movement assembly 3, when the lifting screw 22 rotates, the lifting nut 23 moves up and down along the screw, driving the transverse movement assembly 3 to lift together, and the pipeline clamping member 42 also lifts together, so as to adjust the height of the clamping part 421. Through the lifting structure of the lifting screw 22 and the lifting nut 23 in the embodiment, the precision and stability of the lifting are significantly improved, the smooth lifting process is ensured, and the equipment damage or safety hazards caused by sudden impact or vibration are avoided.

[0041] With reference to Figure 3In the embodiment, the lifting driving member 21 is a lifting driving handle, one end of the lifting driving handle is fixedly connected with the top end of the lifting screw rod 22 in the support member 1, and the other end of the lifting driving handle is arranged above the top end of the support member 1 and can rotate around the axis of the lifting screw rod 22. Specifically, the lifting driving handle is a rocker arm, the rocker arm is arranged above the top end of the support member 1, one end of the rocker arm is inserted into the top end of the support member 1 and is fixedly connected with the top end of the lifting screw rod 22. In this way, when the rocker arm is rotated, the rocker arm moves in a circular motion around the axis of the lifting screw rod 22, the lifting screw rod 22 is driven by the rocker arm to rotate, the lifting nut 23 is driven by the screw thread of the lifting screw rod 22 to move up and down, and the pipeline clamping member 42 is also moved up and down, so that the height position of the clamping part 421 is manually adjusted. Through the embodiment, the simple lifting driving handle structure is adopted to drive the pipeline clamping member 42 to move up and down in a manual mode, the operation of the operator is facilitated, and the disassembly and assembly efficiency is improved.

[0042] With reference to the foregoing Figure 3 In the embodiment, the lifting assembly 2 further comprises an upper limiting block 24 and a lower limiting block 25, the upper limiting block 24 and the lower limiting block 25 are arranged in the support member 1 in an up-down interval, respectively, and the top end and the bottom end of the lifting screw rod 22 are rotatably arranged in the upper limiting block 24 and the lower limiting block 25, respectively. Specifically, in order to realize the rotation of the lifting screw rod 22 in the support member 1, two limiting blocks are arranged in the inner cavity of the support member 1, which are the upper limiting block 24 and the lower limiting block 25, respectively. The upper limiting block 24 and the lower limiting block 25 are fixed in the inner cavity of the support member 1 in an up-down interval, respectively, and are fastened by screws. The upper limiting block 24 is arranged close to the top end of the support member 1, and the distance between the upper limiting block 24 and the lower limiting block 25 matches the length of the lifting screw rod 22. Holes are arranged in the upper limiting block 24 and the lower limiting block 25, respectively, and the top end and the bottom end of the lifting screw rod 22 are inserted into the holes of the upper limiting block 24 and the lower limiting block 25, respectively, so that the lifting screw rod 22 can rotate. A snap spring is further arranged in the hole of the lower limiting block, and the snap spring is connected with the bottom end of the lifting screw rod 22 to provide a certain buffer for the lifting nut 23 and reduce the impact. The lifting nut 23 is located between the upper limiting block 24 and the lower limiting block 25, and the lifting height range of the lifting nut 23 is limited between the upper limiting block 24 and the lower limiting block 25. Through the embodiment, the rotation of the lifting screw rod 22 is realized by the upper and lower limiting blocks 25, and the lifting height range of the lifting nut 23 is also limited, which is simple in structure, convenient to install, and low in processing cost.

[0043] With reference to the foregoing Figure 4 and Figure 5In the embodiment, the inner wall of the support 1 is provided with a lifting limiting groove 11 in the lifting direction, the lifting nut 23 is provided with a lifting limiting protrusion 233, and the lifting limiting protrusion 233 is arranged in the lifting limiting groove 11. Specifically, during lifting, the lifting nut 23 needs to bear the weight of the horizontal moving assembly 3 and the front and rear moving assembly 4, and the lifting nut 23 may deviate, thereby affecting the stability and precision of the tooling. By arranging the lifting limiting groove 11 on the inner wall of the support 1 and arranging the matching lifting limiting protrusion 233 on the lifting nut 23, the unexpected movement of the lifting nut 23 can be effectively prevented, and the smooth lifting of the lifting nut 23 along the predetermined path can be ensured. Specifically, the support 1 can be a support sleeve, the lifting limiting groove 11 is arranged on the inner wall of the sleeve, and the lifting limiting groove 11 is arranged on the inner wall of the sleeve in the lifting direction, for guiding and limiting the movement path of the lifting nut 23. The lifting limiting protrusion 233 is arranged on the outer side of the lifting nut 23, the shape and size of the lifting limiting protrusion 233 are matched with the lifting limiting groove 11, the lifting limiting protrusion 233 is embedded in the lifting limiting groove 11, and the two are tightly matched. When the lifting driving member 21 drives the lifting screw 22 to rotate, the lifting nut 23 moves up and down along the screw, and at the same time, the lifting limiting protrusion 233 slides in the lifting limiting groove 11. Since the lifting limiting protrusion 233 is limited in the lifting limiting groove 11, the lifting nut 23 can only move along the linear path, and the lateral deviation is avoided. Through the embodiment, by introducing the design of the lifting limiting groove 11 and the lifting limiting protrusion 233, the stability and precision of the lifting assembly 2 are significantly improved.

[0044] With reference to the foregoing Figure 4 and Figure 5In the embodiment, the side wall of the support 1 is provided with a mounting opening 12 penetrating the side wall in the lifting direction, and the lifting nut 23 is connected to the horizontal moving assembly 3 through the mounting opening 12. Specifically, since the lifting assembly 2 is installed in the inner cavity of the support 1, it is inconvenient to install the lifting nut 23 and the horizontal moving assembly 3. Therefore, by providing the mounting opening 12 penetrating the side wall of the support 1 in the lifting direction, the lifting nut 23 can be directly connected to the horizontal moving assembly 3 through the mounting opening 12, which simplifies the installation steps and improves the work efficiency. Specifically, the mounting opening 12 penetrates the side wall of the support 1 in the lifting direction, allowing the lifting nut 23 to partially penetrate out and be connected to the horizontal moving assembly 3. The part of the lifting nut 23 penetrating the mounting opening 12 is connected to the horizontal moving assembly 3. The part of the lifting nut 23 penetrating the mounting opening 12 is provided with a mounting base 231, and the horizontal moving assembly 3 is installed on the mounting base 231. The horizontal moving assembly 3 is responsible for horizontal movement, ensuring that the pipeline clamp 42 can be adjusted to the target position. Through the embodiment, the mounting opening 12 is provided on the side wall of the support 1, and the operator can conveniently connect and disassemble the lifting nut 23 and the horizontal moving assembly 3 without disassembling the support 1 or other assemblies, without the need for additional tools or complex steps, saving time and manpower and improving work efficiency.

[0045] With reference to Figure 6 In an embodiment, the horizontal moving assembly 3 comprises a horizontal moving base, a horizontal moving drive 31, a horizontal moving screw 32, and a horizontal moving nut 33. The horizontal moving base is fixedly arranged on the lifting assembly 2. The horizontal moving screw 32 is rotatably arranged on the horizontal moving base. The horizontal moving drive 31 is connected to the horizontal moving screw 32 to drive the rotation of the horizontal moving screw 32. The horizontal moving nut 33 is threadedly connected to the horizontal moving screw 32. The horizontal moving nut 33 is connected to the front-back moving assembly 4 to drive the horizontal movement of the front-back moving assembly 4 along the horizontal direction of the support 1. Specifically, the horizontal moving base is fixedly arranged on the lifting nut 23 of the lifting assembly 2, providing stable support for the horizontal moving assembly 3. The horizontal moving drive 31 is a power source for driving the rotation of the horizontal moving screw 32, which can be an electric motor or other forms of power device. The horizontal moving drive 31 provides precise rotary motion by being connected to the horizontal moving screw 32. The horizontal moving screw 32 is rotatably arranged on the horizontal moving base and cooperates with the horizontal moving nut 33 to realize horizontal movement by rotation. The horizontal moving nut 33 is threadedly connected to the horizontal moving screw 32 and connected to the front-back moving assembly 4. When the horizontal moving screw 32 rotates, the horizontal moving nut 33 moves left and right along the screw, driving the front-back moving assembly 4 and the pipeline clamp 42 to move left and right, thereby adjusting the left-right position of the clamping portion 421. Through the horizontal moving structure of the horizontal moving screw 32 and the horizontal moving nut 33 in the embodiment, the precision and stability of horizontal movement are significantly improved, ensuring a smooth horizontal movement process and avoiding equipment damage or safety hazards caused by sudden impact or vibration.

[0046] With reference to the foregoing Figure 6 In the embodiment, the horizontal movement driving member 31 is a horizontal movement driving handle, one end of which is connected with one end of the horizontal movement screw rod 32. Specifically, the horizontal movement driving handle is a rocker, one end of which is connected with one end of the horizontal movement screw rod 32, and the other end of the horizontal movement screw rod 32 is fixedly connected with the rocker. When the rocker is rotated, the rocker rotates around the axis of the horizontal movement screw rod 32, and the horizontal movement screw rod 32 is rotated under the driving of the rocker. The horizontal movement nut 33 is driven to move horizontally under the thread driving of the horizontal movement screw rod 32, and the pipeline clamping member 42 is also moved horizontally, so as to realize the manual adjustment of the horizontal position of the clamping part 421. Through the embodiment, the simple lifting driving handle structure is adopted to drive the pipeline clamping member 42 to move horizontally in a manual manner, which is convenient for the operator to operate and improves the disassembly and assembly efficiency.

[0047] With reference to the foregoing Figure 6 In the embodiment, the horizontal movement base includes two support blocks 5 arranged horizontally and spaced apart, and two ends of the horizontal movement screw rod 32 are rotatably arranged on the two support blocks 5. Specifically, in order to realize the rotation of the horizontal movement screw rod 32 on the horizontal movement base, the horizontal movement base includes two support blocks 5, i.e., a left support block 34 and a right support block 35, which are fixedly arranged on the mounting base 231 of the lifting nut 23 in a left-right spaced apart manner. The distance between the left support block 34 and the right support block 35 matches the length of the horizontal movement screw rod 32. The left support block 34 and the right support block 35 are both provided with a hole position, and the top end and the bottom end of the horizontal movement screw rod 32 are respectively inserted into the hole positions of the left support block 34 and the right support block 35, so that the horizontal movement screw rod 32 can be rotated. The horizontal movement nut 33 is located between the left support block 34 and the right support block 35, and the horizontal movement width range of the horizontal movement nut 33 is limited between the left support block 34 and the right support block 35. In order to improve the stability of the horizontal movement nut 33 during the left-right movement, the horizontal movement nut 33 can also be provided with a sliding block structure embedded into the sliding groove 232 of the mounting base 231 to slide left and right along the sliding groove 232, thereby improving the stability. Through the embodiment, the left-right support blocks 35 are used to realize the rotation of the horizontal movement screw rod 32, and the horizontal movement width range of the horizontal movement nut 33 is also limited, which is simple in structure, convenient to install, and low in processing cost.

[0048] With reference to the foregoing Figure 4 and Figure 6In the embodiment, the transverse base is embeddedly installed with the lifting assembly 2. Specifically, the transverse base (two support blocks) is embeddedly installed with the lifting assembly 2 (the installation base 231 of the lifting nut 23). Specifically, the lifting nut 23 is formed with the installation base 231 on one side of the installation opening 12, the installation base 231 is provided with a sliding groove 232 in the left-right direction, and the back surfaces of the two support blocks 5 are embedded in the sliding groove 232 from both sides of the sliding groove 232, so as to achieve the embedded installation of the two support blocks 5 and the installation base 231. Of course, it can be understood that other embedded structures can also be used, which are not limited herein. Through the embodiment, the transverse base is installed with the lifting assembly 2 by embedding, which is simple and convenient to install, easy to operate, and improves the work efficiency.

[0049] With reference to Figure 6 In an embodiment, the front-rear moving assembly 4 includes a front-rear support base 41, which is fixedly arranged on the transverse moving assembly 3, and the rear end of the pipeline clamping piece 42 is detachably connected with the front-rear support base 41 along the front-rear direction of the support 1. Specifically, the front-rear support base 41 is fixedly installed on the transverse moving nut 33 of the transverse moving assembly 3, and provides stable support for the pipeline clamping piece 42. The front end of the pipeline clamping piece 42 is formed with a clamping portion 421 for clamping the outer periphery of the pipeline. In order to adapt to different pipe diameters, the embodiment is provided with a plurality of pipeline clamping pieces 42, the sizes of the clamping portions 421 on each pipeline clamping piece 42 are different, so as to clamp pipelines with different diameters. The rear end of the pipeline clamping piece 42 is detachably connected with the front-rear support base 41, which is convenient for quick installation and disassembly, adapts to pipelines with different sizes and shapes, improves the versatility, and the detachable connection between the two can be achieved in various ways, such as screw fastening, buckle fixing, and embedded fixing, which are not limited herein. The pipeline clamping piece 42 and the front-rear support base 41 both have a certain length and extend along the front-rear direction. The rear end of the pipeline clamping piece 42 is detachably connected with the front-rear support base 41 along the front-rear direction of the support 1, which allows the operator to quickly adjust the front-rear position as needed. The operator can easily achieve the installation and disassembly of the pipeline clamping piece 42 by loosening or fastening the connecting components (such as bolts, buckles, etc.). When it is necessary to move the pipeline clamping piece 42, the operator can loosen the connecting components, fix them again after adjusting to the appropriate position, and ensure that the clamping piece can accurately align with the target position, which significantly improves the operation convenience and flexibility of the front-rear moving assembly 4.

[0050] With reference to Figure 6In the embodiment, the rear end of the pipeline clamping piece 42 is provided with a waist-shaped hole 422 extending in the front-rear direction of the support piece 1, and the rear end of the pipeline clamping piece 42 is detachably fixed to the upper surface of the front-rear support base 41 through the waist-shaped hole 422 by a fastener 43.

Specifically, since the Foreline is usually heavy, the front and rear support base 41 needs to have good support capacity. Therefore, the front and rear support base 41 of the present embodiment adopts a triangular beam as a support structure, which utilizes the stability of the triangular shape to enhance the rigidity and load capacity of the support base, so as to ensure that the support base remains stable when bearing a large load and improve the safety and reliability of the whole tool. Specifically, the front and rear support base 41 adopts a triangular beam structure, one of the right angle edges in the height direction is fixed with the horizontal moving nut 33 of the horizontal moving assembly 3, and the other right angle edge in the front and rear direction is detachably connected with the pipeline clamping piece 42. The triangular beam of the present embodiment can also be an integral structure with the horizontal moving nut 33, further enhancing the support performance. The upper surface of the right angle edge in the front and rear direction of the triangular beam is provided with the above-mentioned three threaded holes, and three screws pass through the waist-shaped holes 422 on the pipeline clamping piece 42 and are respectively screwed with the three threaded holes, so as to facilitate quick installation and disassembly, adapt to pipelines of different sizes and shapes, and adjust the front and rear positions. Through the present embodiment, the triangular beam structure is introduced as the front and rear support base 41, which utilizes the stability of the triangular shape to enhance the rigidity of the support base, so as to ensure that the support base remains stable when bearing a large load. The firm structure design improves the safety of the whole tool, especially when handling heavy pipelines, reduces the risk caused by unstable support, and the compact design of the triangular beam saves space, so that the tool can work efficiently in the limited operation space between the cavity and the gas tank.

[0052] With reference to Figure 1 In an embodiment, the bottom end of the support piece 1 is provided with a counterweight 5. Specifically, when the pipeline auxiliary disassembly tool is used, the support piece 1 may be tilted or unstable due to external force or heavy Foreline pipeline 7. The counterweight 5, usually made of metal or other high-density materials, is used to increase the weight of the support piece 1 and improve the stability. By increasing the weight of the support piece 1, the center of gravity of the tool is lowered, and its stability on the ground is improved. Through the present embodiment, the addition of the counterweight 5 can significantly improve the overall stability and safety of the tool, ensuring that it will not tilt or overturn during operation due to external interference.

[0053] With reference to Figure 1In an embodiment, a handrail 6 is arranged on the side wall of the support 1. Specifically, when operating the pipeline auxiliary dismounting tool, the operator needs to frequently adjust the position and angle. By arranging the handrail 6 on the side wall of the support 1, the operator can push or pull the tool to adjust the position. The handrail 6 is arranged on the side wall of the support 1, which ensures that the position is easy to hold by the operator. The handrail 6 can be fixed on the support 1 by bolts, welding or other means, which ensures that it is firm and reliable. By arranging the handrail 6 on the side wall of the support 1, the operator can more conveniently push or pull the tool to adjust the position, which improves the convenience and efficiency of the operation.
