Description

Technical Field

[0001] This invention relates to the field of hose processing technology, and specifically to a hose cutting machine. Background Technology

[0002] Rubber hoses generally consist of an outer rubber layer, a steel wire reinforcement layer, and an inner rubber layer. Common types include spiral wound hoses, braided hoses, and fabric-reinforced hoses. They are mainly used for conveying gases, liquids, slurries, or granular materials.

[0003] In the processing of rubber hoses, it is usually necessary to unseal the semi-finished rubber hose rolls that are coiled and bundled, cut them to the required length, and then install metal connectors at the cut ends. Because the semi-finished rubber hose rolls are coiled and bundled for a long time, their resilience is reduced and their plasticity is increased, thus tending to remain bent. Therefore, they are difficult to straighten after unsealing, which in turn increases the difficulty of length measurement, reduces the accuracy of cutting operations, and ultimately reduces the quality of the final product. Summary of the Invention

[0007] It also includes a pressing module, which includes a pressing plate, a support shaft, and a support base; both ends of the support shaft are connected to the support base, and the support base is connected to the outer wall of the placement frame; the pressing plate has a through hole, and the through hole of the pressing plate is sleeved on the surface of the support shaft.

[0008] The pressing plate includes a C-shaped plate, a crimping line, an abutting plate, and a counterweight. The through hole is disposed at one end of the C-shaped plate, and the other end of the C-shaped plate is connected to the crimping line; the abutting plate is disposed at one end of the C-shaped plate close to the through hole; the abutting plate is located on one side of the C-shaped plate close to the placement rack; the abutting plate is provided with an abutting surface, and the abutting surface is adapted to the lower bottom surface of the outward extending fin; the counterweight is disposed at one end of the C-shaped plate close to the through hole, and the counterweight is located on the side of the C-shaped plate背离 the placement rack.

[0009] The pressing plate further includes connecting blocks and connecting members; the connecting blocks are arranged in pairs and include L-shaped first connecting blocks and factory-shaped second connecting blocks that are equal in size and symmetrical about the left and right. The first connecting block and the second connecting block are respectively located at the axially symmetric positions at both ends of the outer surface of the C-shaped plate and are fixedly connected; the connecting member includes a lower convex portion, and a T-shaped groove is provided on the lower bottom surface of the lower convex portion. The two side walls of the T-shaped groove are respectively adapted to the side walls of the first connecting block and the second connecting block; one end of the T-shaped groove is open, and a plug plate is provided at the other end of the T-shaped groove.

[0010] As a further optimization scheme of the present invention, outward extending fins are provided on the side surface of the placement rack, and the outward extending fins are clamped with the hoop.

[0011] As a further optimization scheme of the present invention, the support module further includes a support, and the support is disposed at one end of the placement rack away from the workbench.

[0012] As a further optimization scheme of the present invention, the limiting plate is perpendicular to the length direction of the placement rack.

[0013] As a further optimization scheme of the present invention, the cross section of the receiving groove is in the shape of being wider at the top and narrower at the bottom.

[0015] As a further optimization scheme of the present invention, auxiliary pressing plates are respectively connected to both sides of the crimping line.

[0016] In summary, the advantages of this invention are: a hose cutting machine, comprising a cutting module, a support module, and a limiting module; the upper surface of the placement frame is provided with a receiving groove for accommodating the hose; the limiting module is connected to the placement frame; the limiting module includes a clamping ring, a lead screw, a handle, and a pressing block; the clamping ring is clamped to the placement frame, the clamping ring has a threaded hole, and the lead screw is placed in the threaded hole through threaded engagement; the top end of the lead screw is connected to the handle; the lower bottom surface of the pressing block is in contact with the receiving groove, the upper surface of the pressing block has a pressing surface, and the pressing surface is located below the bottom end of the lead screw; a limiting plate is provided at one end of the pressing block near the worktable. When the lead screw rotates to the point where its lower end presses against the pressing surface, the pressing block and the receiving groove are fixedly connected by friction; when the lead screw rotates to the point where its lower end separates from the pressing surface, the lower bottom surface of the pressing block naturally presses against the receiving groove, at which point the pressing block can be pushed to slide. When the pressing block slides, the horizontal distance between the limiting plate and the cutting wheel changes. Workers continuously measure the distance between the cutting wheel and the limiting plate, adjusting the position of the limiting module until the distance between the cutting wheel and the limiting plate equals the target processing length of the finished hose. The semi-finished hose is then placed in the receiving groove for cutting. This method is far more convenient than directly measuring the length of the bent semi-finished hose using traditional techniques, significantly reducing the difficulty of length measurement. The receiving groove also has a straightening effect on the semi-finished hose, and combined with manual operation, it allows for a relatively high degree of straightness, thereby improving cutting accuracy and ensuring product quality.

[0017] The invention also includes a crimping module, which comprises a pressure plate, a support shaft, and a support base. The pressure plate includes a C-shaped plate, a crimping strip, an abutment plate, and a counterweight. A semi-automatic or fully automatic robotic arm grasps the pressure plate and presses it down until the lower surface of the crimping strip is crimped against the top of the semi-finished hose, further improving the straightness of the semi-finished hose. This method is more convenient than manual pressing and can further improve cutting accuracy and efficiency, ensuring product quality. Attached Figure Description

[0044] Based on the above-described structural features of this application, the implementation methods of this application will be further described as follows:

[0045] Reference Figures 1-3 A hose cutting machine includes a cutting module 1, a support module 2, and a limiting module 3. The support module 2 includes a worktable 21 and a placement frame 22. The placement frame 22 is straight and has a receiving groove on its upper surface for accommodating the hose. The receiving groove is straight. One end of the placement frame 22 is connected to the worktable 21. The cutting module 1 is connected to the worktable 21 (e.g., by bolt fastening, welding, etc.). The limiting module 3 is connected to the placement frame 22. The cutting module 1 is, for example, a disc-type cutting wheel. The cutting wheel is driven by a motor and moves up and down through a ball screw mechanism. When the cutting wheel moves downward, it cuts the workpiece. When the cutting wheel moves upward, it resets. This is a conventional technical solution in the industry and will not be described in detail. The placement frame 22 is arranged perpendicular to the cutting wheel.

[0046] Reference Figure 3 One end of the placement rack 22 is fixedly connected to the workbench 21; a fixed seat 220 is welded to the upper surface of the workbench 21, and a support groove is opened on the upper surface of the fixed seat 220. The shape of the outer bottom surface of the placement rack 22 is adapted to the support groove, and the outer bottom surface of one end of the placement rack 22 is placed in the support groove and welded and fixed.

[0047] Reference Figures 4-6The limiting module 3 includes a clamping ring 31, a lead screw 32, a handle 33, and a pressing block 34. The clamping ring 31 is clamped at both ends to the sides of the placement frame 22, and can slide along the length of the placement frame 22. A threaded hole is provided in the middle of the clamping ring 31, and the lead screw 32 is placed in the threaded hole through a threaded engagement, allowing it to move up and down within the threaded hole when rotated. The top end of the lead screw 32 is connected to the handle 33 (e.g., by bolt fastening, welding fastening, or detachable connection via a spline), and the handle 33 can transmit torque to the lead screw 32. The lower surface of the pressing block 34 fits against the receiving groove, and the upper surface of the pressing block 34 has a pressing surface 342, which is located below the bottom end of the lead screw 32. When the lead screw 32 rotates to the point where its lower end presses against the pressing surface 342, the bottom surface of the pressing block 34 is fixedly connected to the receiving groove by friction. When the lead screw 32 rotates to the point where its lower end separates from the pressing surface 342, the bottom surface of the pressing block 34 naturally presses against the receiving groove. At this time, the operator or a robotic arm can manually or mechanically push the pressing block 34 and / or the clamp 31 (the clamp 31 can push the lead screw 32 and the handle 33 to move at the same speed and in the same direction) to slide along the length of the placement frame 22. The pressing block 34 includes a base support 341, which is a bent plate (preferably a steel plate) whose shape matches the bottom shape of the support groove. A metal sheet (preferably a steel plate) is welded and fixed to the upper end of the base support 341, and the upper surface of the metal sheet is the pressing surface 342. The end of the pressing block 34 near the worktable 21 is provided with a limiting plate 343 (for example, the limiting plate 343 is fastened to the end of the bottom support 341 by welding, bolts, etc.), that is, the limiting plate 343 can also slide along the length direction of the placement frame 22. The limiting plate 343 is perpendicular to the length direction of the placement frame 22, that is, when the limiting plate 343 slides, the horizontal distance between the limiting plate 343 and the cutting wheel changes.

[0048] Reference Figure 2 , 4 In use, slide the limiting module 3 to a suitable position (so that the target processing length of the finished hose 0 is equal to the distance between the cutting wheel and the limiting plate 343), and rotate the handle 33 to drive the lead screw 32 to rotate until the lower end of the lead screw 32 is pressed against the pressing surface 342 of the pressing block 34. At this time, the bottom support 341 is pressed against the receiving groove, thus fixing the position of the limiting plate 343, i.e., the limiting module 3 enters the limiting state. Then, unseal the semi-finished hose roll on the side of the cutting wheel away from the limiting plate 343, grab the material flow front of the semi-finished hose 0 and slide it along the length direction of the receiving groove (under its own weight, the semi-finished hose 0 is naturally pressed against the receiving groove, i.e., the semi-finished hose 0 is placed in the receiving groove, and the receiving groove straightens the semi-finished hose 0), until the material flow front end of the semi-finished hose 0 abuts against the limiting plate 343. Then drive the cutting wheel of the cutting module 1 to rotate and move downward to cut the semi-finished hose 0, thus achieving material cutting.

[0049] Workers continuously measure the distance between the cutting wheel and the limiting plate 343, and adjust the position of the limiting module 3 until the distance between the cutting wheel and the limiting plate 343 equals the target processing length of the finished hose 0. Then, the semi-finished hose 0 is placed in the receiving groove for cutting. This method is much more convenient than directly measuring the length of the bent semi-finished hose 0 in traditional techniques, greatly reducing the difficulty of length measurement. The receiving groove has a certain limiting and straightening effect on the semi-finished hose 0. Combined with manual operation (e.g., the operator directly presses the semi-finished hose 0 to the bottom of the receiving groove by hand), the semi-finished hose 0 can achieve a relatively high straightness, thereby improving the cutting accuracy and ensuring product quality.

[0050] Reference Figure 6 The side of the placement rack 22 is provided with an extended fin 221, which is connected to the hoop 31; the bottom surface of the extended fin 221 is horizontal.

[0051] Reference Figure 2 The support module 2 also includes a support 23, which is located at the end of the placement frame 22 away from the worktable 21. The upper surface of the support 23 is fixedly connected to the lower surface of the placement frame 22, for example, by bolting or welding. The worktable 21 and the support 23 are located at both ends of the placement frame 22 to provide support and ensure that the placement frame 22 is in a horizontal state.

[0052] Reference Figures 4-6 The cross-section of the receiving groove is wider at the top and narrower at the bottom, such as a V-shape, U-shape, or inverted trapezoid.

[0053] Reference Figure 7 A hose cutting machine also includes a crimping module 4. For semi-finished hoses 0 with strong resilience, they cannot be naturally crimped into the receiving groove by their own weight alone, or some parts are raised while others can be naturally crimped into the receiving groove, meaning they are still in a slightly bent or partially bent state. The semi-finished hose 0 can be manually pressed or the crimping module 4 can be used semi-automatically to flatten it into the receiving groove, thereby improving the straightness of the semi-finished hose 0 and further ensuring the accuracy of the cutting.

[0054] Reference Figure 7The pressing module 4 includes a pressure plate 41, a support shaft 42, and a support base 43. Both ends of the support shaft 42 are connected to the support base 43 (e.g., by bolts, welding, etc.), and the support base 43 is connected to the outer wall of the placement rack 22 (e.g., by bolts, welding, etc.). The support base 43 supports the support shaft 42, ensuring that the support shaft 42 is parallel to the placement rack 22; when the receiving groove is aligned with the placement rack 22, the support shaft 42 is parallel to the receiving groove. The pressure plate 41 has a through hole, which is fitted onto the surface of the support shaft 42 and is both rotatable and slidable. That is, the pressure plate 41 can rotate on the surface of the support shaft 42 simultaneously, slide on the surface of the support shaft 42 simultaneously, and rotate and slide simultaneously on the surface of the support shaft 42 simultaneously.

[0055] Reference Figures 8-10 The pressure plate 41 includes a C-shaped plate 411, a crimping strip 412, an abutment plate 413, and a counterweight 414. The C-shaped plate 411 is inverted and placed above one side wall of the placement rack 22. A through hole is located at one end of the C-shaped plate 411, and the other end of the C-shaped plate 411 is connected to the crimping strip 412 (e.g., by bolt connection or integral molding). The abutment plate 413 is located at the end of the C-shaped plate 411 near the through hole and is connected to it (e.g., by bolt connection or integral molding). The abutment plate 413 is located on the side of the C-shaped plate 411 near the placement rack 22. The abutment plate 413 has an abutment surface that is adapted to the lower bottom surface of the extended fin 221 (e.g., by bolt connection or integral molding). Figure 10 As shown, when the pressure plate 41 rotates clockwise, the contact surface of the contact plate 413 presses against and limits the lower surface of the extended fin 221; the counterweight 414 is placed at the end of the C-shaped plate 411 near the through hole and connected to each other (e.g., bolt connection, integral molding, welding fixation, etc.), and the counterweight 414 is located on the side of the C-shaped plate 411 away from the placement frame 22. In the natural state, the counterweight 414 presses down the side of the pressure plate 41 away from the placement frame 22, causing the side of the pressure plate 41 near the placement frame 22 to tilt up (after tilting up, the crimping strip 412 and the receiving groove have a large opening, which makes it convenient for the operator to place their hand in the opening to operate the semi-finished rubber tube 0, such as the aforementioned "grabbing the material flow front of the semi-finished rubber tube 0 and sliding it along the length direction of the receiving groove"). At this time, the contact surface presses against and limits the lower surface of the extended fin 221. After the material feeding is completed (material feeding requires at least two conditions: firstly, the material flow front end of the semi-finished hose 0 abuts against the limiting plate 343; secondly, the semi-finished hose 0 is placed in the receiving tank and pressed together, and the pressing includes, but is not limited to, natural pressing by the weight of the semi-finished hose 0, manual pressing, semi-automatic pressing by manual tools, or fully automatic pressing by mechanical equipment), the worker (semi-automatic) or the robotic arm (fully automatic) grabs the pressure plate 41 and presses it down (e.g. Figure 9As shown (rotating counterclockwise), until the lower surface of the crimping line 412 is crimped to the top of the semi-finished rubber hose 0, further improving the straightness of the semi-finished rubber hose 0, which is more convenient than manual pressing operation, and further improving the cutting accuracy and efficiency, ensuring product quality.

[0056] The lower surface of the crimping line 412 is arc-shaped, so that the lower surface of the crimping line 412 can better fit and crimp to the top of the semi-finished rubber hose 0, to ensure that when crimping, the semi-finished rubber hose 0 can be prevented from being displaced and disengaged due to uneven load.

[0057] Refer to Figure 11 , since the limiting module 3 can move on the placement rack 22 and the length of the pressing plate 41 is a fixed value, when the distance from the front end of the placement rack 22 to the limiting module 3 is much greater than the length of the pressing plate 41 (such as more than 3 times), the crimping effect of the pressing plate 41 will be relatively poor, that is, a large range of the semi-finished rubber hose 0 cannot be straightened by the crimping of the pressing plate 41. Therefore, multiple pressing plates 41 can be provided to jointly straighten the semi-finished rubber hose 0 by crimping.

[0058] Refer to Figures 11-14 , the pressing plate 41 further includes a connecting block 415 and a connecting member 44; the connecting blocks 415 are arranged in pairs and include a 7-shaped first connecting block and a factory-shaped second connecting block with equal size and left-right symmetrical shape. The first connecting block and the second connecting block are respectively located at the axially symmetric positions at both ends of the outer surface of the C-shaped plate 411 and are fixedly connected (such as bolt fastening, integral molding or welding fixation, etc.). When two pressing plates 41 are connected end to end and aligned, at the joint position, the adjacent first connecting block and second connecting block jointly form a T-shaped connecting block 415 (as Figure 13 shown in 14 ).

[0059] Refer to Figure 14 , the connecting block 415 includes a radially limiting plate 4151, an axially limiting plate 4152 and a clamping bottom plate 4153 that are connected to each other (such as bolt fastening, integral molding, etc.). The radially limiting plate 4151 has a radian, and the radian of the radially limiting plate 4151 is adapted to the radian of the outer surface of the C-shaped plate 411; the axially limiting plate 4152 has a radian, and the radian of the axially limiting plate 4152 is adapted to the radian of the outer surface of the C-shaped plate 411.

[0060] Refer to Figure 11 , 15Compared with 16, connector 44 includes a lower protrusion 441, the lower bottom surface of which is provided with a T-shaped groove 4411 adapted to the T-shaped connecting block 415. The two side walls of the T-shaped groove 4411 are adapted to the side walls of the first connecting block and the second connecting block, respectively; one end of the T-shaped groove 4411 is open, and the other end of the T-shaped groove 4411 is provided with a blocking plate 4412. The lower bottom surface of the lower protrusion 441 is curved, and the curvature of the lower bottom surface of the lower protrusion 441 is adapted to the curvature of the outer surface of the C-shaped plate 411. The length direction of the T-shaped groove 4411 is arc-shaped, and the curvature of the arc-shaped T-shaped groove 4411 is adapted to the curvature of the outer surface of the C-shaped plate 411.

[0061] Reference Figures 12-16 In use, workers manually or using a robotic arm connect and align adjacent pressure plates 41 end to end, forming a T-shaped connecting block 415 at the joint. One end of the opening of the T-shaped groove 4411 is aligned with the end of the T-shaped connecting block 415 away from the snap-fit ​​base plate 4153 and pushed along the arc of the C-shaped plate 411, causing the T-shaped groove 4411 to fit onto the surface of the T-shaped connecting block 415. The fitting is complete when the side of the lower protrusion 441 at the opening of the T-shaped groove 4411 abuts against the snap-fit ​​base plate 4153. The T-shaped groove 4411 and the T-shaped connecting block 415 are connected by friction. The T-shaped groove 4411 applies a clamping force to the first and second connecting blocks to achieve the connection between adjacent pressure plates 41.

[0062] Reference Figure 15 and 17 The connector 44 also includes an extension 442, which is located in the opening direction of the T-slot 4411; the extension 442 is provided with a gripper groove 4421. The work station of the worker or robotic arm is located on the opposite side of the crimping module 4 (e.g., Figure 17 When the left side of the placement rack 22 is shown, the pressure plate 41 is pressed down by the extension 442 below the gripper groove 4421 (as mentioned above, "the worker manually or with a robotic arm grips the pressure plate 41 and presses it down until the lower surface of the crimping strip 412 is crimped to the top of the semi-finished hose 0"), which is more convenient. After the connector 44 is installed on the pressure plate 41, the extension 442 is in a raised state, that is, the gripper groove 4421 is also in a raised state, which not only makes it easier for the worker or robotic arm to grip, but also facilitates the transmission of downward pressure.

[0063] Reference Figures 18-19Several pressure plates 41 are pre-set on the support shaft 42. The pressure plates 41 can slide back and forth along the support shaft 42 on the left and right sides of the limiting module 3, for example, from the left side of the limiting module 3 (i.e. the side closer to the worktable 21) to the right side (i.e. the side away from the worktable 21), and from the right side of the limiting module 3 (i.e. the side away from the worktable 21) to the left side (i.e. the side closer to the worktable 21). Several pressure plates 41 on the left side of the limiting module 3 (i.e., the side closer to the worktable 21) are interconnected by connectors 44 to perform a pressing operation on the semi-finished hose 0. When it is necessary to cut a semi-finished hose 0 with a longer target processing length, the pressure plates 41 on the right side of the limiting module 3 (i.e., the side away from the worktable 21) need to be moved to the left side and spliced ​​to increase the pressing length. When it is necessary to cut a semi-finished hose 0 with a shorter target processing length, some of the pressure plates 41 on the left side of the limiting module 3 (i.e., the side closer to the worktable 21) need to be moved to the right side and left idle to reduce the pressing length.

[0064] Reference Figure 19 There is a gap between the outermost end of the bottom surface of the clamp ring 31 and the inner surface of the C-shaped plate 411 near the support shaft 42. When the abutment plate 413 rotates to the point where the abutment surface creates a gap with the bottom surface of the clamp ring 31, the crimping strip 412 is located above the upper surface of the clamp ring 31. This ensures that when the pressure plate 41 can slide back and forth along the support shaft 42 on both sides of the limiting module 3, the clamp ring 31 will not get stuck with the pressure plate 41. When it is necessary to cut a semi-finished hose 0 with a longer / shorter target processing length, the limiting state of the limiting module 3 needs to be released. At this time, the pressure plate 41 needs to be moved. At this time, the handle 33 and the lead screw 32 are rotated until the lead screw 32 is removed from the clamp ring 31, ensuring that the handle 33 and the lead screw 32 do not obstruct the movement of the pressure plate 41, and at the same time facilitate the movement of the crimping block 34 (and the clamp ring 31). After the crimping block 34 (and the clamping ring 31) are moved to the required position, reinstall and rotate the handle 33 and the lead screw 32 until the limit module 3 enters the limit state.

[0065] Reference Figure 20Auxiliary pressure plates 4121 are connected to both sides of the crimping strip 412. The auxiliary pressure plates 4121 are made of elastic material, such as rubber. The end of the auxiliary pressure plate 4121 away from the crimping strip 412 is elastically pressed against the upper surface of the side wall of the placement frame 22. The lower surface of the crimping strip 412, the lower surface of the auxiliary pressure plate 4121, and the receiving groove together form a cylindrical space. As the pressure plate 41 is pressed down, the auxiliary pressure plate 4121 deforms until the lower surface of the auxiliary pressure plate 4121 gradually fits against the receiving groove from the outside to the inside. During the process of the lower surface of the auxiliary pressure plate 4121 gradually fitting against the receiving groove, the cross-sectional area of ​​the cylindrical space gradually decreases, that is, the space where the semi-finished rubber tube 0 is located gradually decreases. Finally, the crimping strip 412, the auxiliary pressure plate 4121, and the receiving groove work together to crimp and restrict the semi-finished rubber tube 0 to the bottom of the receiving groove, thereby improving the straightness of the semi-finished rubber tube 0, further improving cutting accuracy, improving product quality, reducing the defect rate, reducing material waste, and reducing production costs.

[0066] Reference Figure 21 Repeated disassembly and reassembly of connector 44 will cause wear at the contact point between connector 44 and T-shaped connecting block 415, which reduces the reliability of the friction connection and increases the probability of failure. The bottom end of extension 442 abuts against the upper surface of crimping strip 412. The lower surface of crimping strip 412 is provided with a countersunk hole, in which a removable bolt or removable screw 443 is provided. The removable bolt / removable screw 443 is detachably connected to the bottom end of extension 442 through a threaded hole. The threaded hole is located on the end face of the bottom end of extension 442, thereby improving the connection reliability between connector 44 and C-shaped plate 411 and between connector 44 and T-shaped connecting block 415, and ensuring equipment safety.

[0067] Reference Figure 22 The crimping module 4 also includes accessory handles 45, which include a bonding plate 451 fixedly connected to each other (e.g., integrally molded), a C-shaped horizontal handle 452, and a buckle 453. The buckle 453 is detachably snapped into the gripper groove 4421. The lower surface of the bonding plate 451 naturally fits against the outer surface of the connector 44, and the horizontal handle 452 is located on the outer surface of the bonding plate 451. Multiple accessory handles 45 are provided, and the horizontal handles 452 of different models are located at different positions on the bonding plate 451. Workers or robotic arms can select different models of accessory handles 45 according to the height of the placement frame 22 to improve operational comfort. For example, when the height of the placement frame 22 is low, the accessory handle 45 with the horizontal handle 452 above the bonding plate 451 is selected for easy gripping; when the height of the placement frame 22 is high, the accessory handle 45 with the horizontal handle 452 below the bonding plate 451 is selected for easy gripping. Different models of accessory handles 45 are used to improve the compatibility of the invention and adapt to more working scenarios while ensuring that the connectors 44 adopt standardized and batch operations (i.e., the requirements of traditional batch machining operations).

[0068] Reference Figure 23 The pressing module 4 also includes a pedal switch 46, which is fixedly connected to the placement frame 22 via a pedal mounting base 460. The pedal switch 46 is connected to the end of the abutment plate 413 near the placement frame 22 via a connecting wire 47. An operator or robotic arm can drive the pressing plate 41 to press down by stepping on the pedal switch 46 (e.g., ...). Figure 23 As shown in the view, when the pressure plate 41 rotates counterclockwise, it is in a downward pressing state. It can be used as an auxiliary for pressing operations through the gripper groove 4421, or it can independently press down the pressure plate 41 by gripping the gripper groove 4421, thus providing a more flexible operation method.
