Description

Technical Field

[0001] This invention relates to the technical field of seedling support, and more particularly to a fixing device for assisting the growth of seedlings in municipal landscaping. Background Technology

[0002] Municipal landscaping seedlings refer to plant materials used in urban greening, parks, streets, squares, and other municipal engineering projects. These seedlings typically need to possess strong adaptability, resilience, and ornamental value to meet the needs of the urban environment. In the early stages of transplanting municipal landscaping seedlings, it is generally necessary to use fixing devices to provide auxiliary support. These supporting and fixing devices are mainly used for the following purposes:

[0003] Protecting seedlings from wind damage: The root system of newly transplanted seedlings is not yet fully established, and strong winds may cause the seedlings to tilt or fall over. Support devices can provide additional stability and prevent the seedlings from being blown over by the wind.

[0004] Promote root growth: By providing support, the swaying of seedlings caused by external forces can be reduced, which is conducive to the stability and growth of the root system, thereby improving the survival rate of seedlings.

[0005] Aesthetics and Neatness: Support devices can keep the seedlings upright, maintaining the neatness and beauty of the landscape. Especially in densely populated areas such as green spaces and parks, a neat arrangement of seedlings is more in line with the requirements for viewing.

[0006] Currently, most fixing devices are made of wood, consisting of multiple timbers erected around the sapling to provide circumferential support. The fixing device and the sapling need to be secured together. However, once the fixing device and the sapling are secured, the following defects occur:

[0007] 1. Since the seedlings are transplanted during the seedling and growth stages, the seedlings grow rapidly in height during this production stage. If the fixing device and the seedling are kept too tight for a long time, it will restrict the ability of the seedling's main trunk to grow upward. This is especially true during the rapid growth stage, when the fixing device and the seedling are integrated and the fixing device is fixed to the ground, which will hinder the seedling from extending upward.

[0008] 2. Since the height of the fixing device is fixed, the top part cannot be effectively supported after the seedling grows taller, causing the seedling to bend or tilt due to lack of support.

[0009] 3. Although height-adjustable fixing devices can be used to gradually adjust the height of the support frame as the seedlings grow, thus avoiding limiting the height growth of the seedlings, this requires manual intervention periodically, which is too inconvenient. Summary of the Invention

[0010] In view of the above-mentioned problems of existing technology, a fixing device for assisting the growth of seedlings in municipal gardens is proposed.

[0011] This application provides a fixing device for assisting the growth of municipal garden seedlings. Its purpose is to allow the seedling to adjust its height autonomously as it grows, effectively supporting the seedling without hindering its upward growth.

[0012] The technical solution of this invention is as follows: a fixing device for assisting the growth of municipal garden seedlings, a seedling support mechanism for supporting and fixing seedlings, the seedling support mechanism comprising: a plurality of support units arranged around the seedlings, the lower ends of the support units being set on the ground; fixing wires, the fixing wires fixing the seedlings and the support units; each support unit further comprising: an arc-shaped clamping block, abutting against the side wall of the seedling, the fixing wires fixing the clamping block and the seedling; a ground-mounted box, set on the ground, the ground-mounted box having a sliding limiter on its inner wall near the box opening by two sliding rods. The slide has a balance block at its upper end, and a transmission bar is hinged between the balance block and the clamping block. A one-way traveling component is located at the lower end of the slide and inside the ground-contact box. The one-way traveling component includes a partition on the inner wall of the ground-contact box. A traveling seat is elastically and movably positioned vertically at the lower end of the slide via an upward-pulling assembly, and the partition is located below the traveling seat. Two toothed plates are symmetrically arranged at the upper end of the partition about the traveling seat. Toothed blocks are movably arranged on the side walls of the traveling seat near the two toothed plates via an elastic assembly, and the toothed blocks mesh with the corresponding toothed plates.

[0013] Furthermore, the elastic component includes an elastic groove formed on the side wall of the travel seat, an elastic reset member is connected to the bottom of the elastic groove, the other end of the elastic reset member is connected to the tooth block, the tooth block is limited and slidably disposed in the elastic groove, and the end of the tooth block away from the elastic reset member passes through the elastic groove.

[0014] Furthermore, the support unit also includes a return component disposed on the travel seat. The return component includes return rods symmetrically disposed on both side walls of the travel seat, and the return rods are located directly below the toothed block. A return groove is provided on the side wall of the toothed plate near the travel seat at the position corresponding to the return rod. The end of the return rod away from the travel seat extends movably into the return groove. The return groove includes an upper groove, a lower inclined arc groove, a lower return groove, and a rising groove that are connected in sequence. The upper groove and the lower return groove are arranged in parallel, and the lower inclined arc groove is inclined. The length of the upper groove is shorter than the length of the lower return groove.

[0015] Furthermore, the pull-up assembly includes two pull rods symmetrically arranged on the upper end of the travel seat, and two pull-up slots symmetrically opened at the lower end of the slide. The end of the pull rod away from the travel seat extends movably into the corresponding pull-up slot. The pull rod and the pull-up slot are slidably connected. A pull-up reset member is sleeved on the pull rod located between the travel seat and the slide, and the two ends of the pull-up reset member are respectively connected to the travel seat and the slide.

[0016] Furthermore, the support unit also includes a fertilization component disposed within the ground-mounted box. The fertilization component includes a bag-changing opening located at the bottom of the ground-mounted box at the end furthest from the seedling. A matching bag-changing plate is slidably and sealed within the bag-changing opening. Multiple storage bags containing nutrient solution are arranged at the bottom of the inner box of the ground-mounted box. A bag-removing opening is provided at the end of the ground-mounted box closest to the seedling. A plug is inserted into the bag-removing opening. A bag-breaking needle is provided at the end of the plug near the storage bag, and the other end of the bag-breaking needle extends into the ground-mounted box. A liquid outlet is provided at the bottom of the ground-mounted box. A bag-pushing assembly for moving the storage bags is provided at the lower end of the traveling seat.

[0017] Furthermore, the push bag assembly includes an elongated push slot on the partition, and two compensation members are symmetrically arranged on the side wall of the traveling seat. The two compensation members pass through the push slot and are jointly provided with a push plate, which movably abuts against the liquid storage bag away from the seedling.

[0018] Furthermore, the liquid outlet includes a liquid outlet hole formed at the bottom of the box, a ball chamber is provided inside the liquid outlet hole, and a liquid outlet pipe is provided at the lower end of the ball chamber.

[0019] Furthermore, the compensation component includes a compensation ring disposed on the side of the push plate away from the liquid storage bag, a compensation rod movably passing through the compensation ring, and one end of the compensation rod passing through the push slot and disposed on the side wall of the travel seat.

[0020] Furthermore, multiple petal-shaped bag-supporting pieces are evenly distributed in a ring on the needle wall near the needle tip of the bag-breaking needle.

[0021] Furthermore, the bottom of the inner box of the ground-mounted box near the liquid outlet is set as an inclined surface facing the liquid outlet, and the liquid storage bag is set tightly against the inner box wall of the ground-mounted box.

[0022] The beneficial effects of this invention are:

[0023] 1. The clamps on the support unit attached to the seedling are fixed by the fixing wire. When the seedling grows upward, the clamps move upward, allowing the traveling seat to move normally towards the seedling. The teeth that mesh with the toothed plate prevent the teeth and traveling seat from moving backward. While supporting and fixing the seedling, it does not affect the upward growth of the seedling. When the seedling is blown by strong winds in severe weather, the multiple sets of support units distributed in a ring array not only provide good support and fixation for the seedling, but also provide good support and fixation for the seedling.

[0024] 2. When the seedlings grow vertically, the support unit will automatically adjust its fixed position to the seedlings according to the changes in seedling height, eliminating the need for regular manual adjustments, thus improving convenience and avoiding the consumption of human resources.

[0025] 3. During the seedling and growth stages, due to the rapid longitudinal growth of the seedlings, after transplanting, when the seedlings grow to a certain height, a storage bag containing nutrient solution will be punctured to automatically fertilize the seedlings, improving the survival rate and growth effect of the seedlings during transplanting and growth stages, and eliminating the need for manual fertilization.

[0038] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0039] Example 1, referring to Figure 1-6This is the first embodiment of the present invention, providing a fixing device for assisting the growth of municipal landscaping seedlings. The seedling support mechanism includes: several support units arranged around the seedling, with the lower ends of the support units inserted and fixed to the ground; a fixing wire 1, which fixes the seedling and the support units; the support unit further includes: an arc-shaped clamping block 2, with a rubber pad connected to the inner wall of the clamping block 2 as a buffer between the clamping block 2 and the seedling; the rubber pad on the inner side of the clamping block 2 is abutted against the side wall of the seedling; the fixing wire 1 fixes the clamping block 2 and the seedling; since the longitudinal growth rate of the seedling is greater than its lateral growth rate, in the early support stage of seedling transplantation, the compressibility of the rubber pad satisfies the lateral growth needs of the seedling while allowing the clamping block 2 to move synchronously during the longitudinal growth of the seedling; and a ground-mounted box 3, with a rod connected to the bottom of the outer box of the ground-mounted box 3. The insertion rod is inserted into the ground. The box opening of the ground-mounted box 3 is fitted with a box cover. A slide block 5 is slidably connected to the inner wall of the ground-mounted box 3 near the box opening via two sliding rods 4. A balance block 6 is connected to the upper end of the slide block 5. A transmission strip 7 is hinged between the balance block 6 and the clamping block 2. A one-way travel component is connected to the lower end of the slide block 5 and is located inside the ground-mounted box 3. The one-way travel component includes a partition 8 connected to the inner wall of the ground-mounted box 3. The lower end of the slide block 5 is connected to an upward pull assembly. The component is elastically and movably connected to the travel seat 9 in the vertical direction, and the partition 8 is located below the travel seat 9. Two toothed plates 10 are symmetrically connected to the upper end of the partition 8 about the travel seat 9. Toothed blocks 11 are movably connected to the two side walls of the travel seat 9 near the two toothed plates 10 through elastic components. The toothed blocks 11 mesh with the corresponding toothed plates 10. The box opening of the ground box 3 is fitted with a box cover. The box cover does not affect the movement of the balance block 6 and reduces the amount of debris falling into the ground box 3.

[0040] Specifically, the clamping block 2 on the support unit attached to the seedling is fixed by the fixing wire 1, so that the clamping block 2 and the seedling are fixed. When the seedling grows, the clamping block 2 moves upward. The clamping block 2 pulls the balance block 6 towards the seedling through the hinged transmission bar 7, and drives the slide 5 to slide on the slide rod 4. While the slide 5 moves towards the seedling, it drives the traveling seat 9 to move synchronously. During the movement, the toothed block 11 is blocked by the inclined surface of the toothed plate 10 and compresses the elastic component multiple times, so that the traveling seat 9 and the slide 5 can move normally without affecting the upward extension of the seedling. When the seedling is blown by strong winds in severe weather, the multiple sets of support units distributed in a ring array not only provide good support and fixation for the seedling, but also provide good support and fixation for the seedling.

[0041] Reference Figure 6The elastic component includes an elastic groove 12 formed on the side wall of the travel seat 9. An elastic reset member 13 is connected to the bottom of the elastic groove 12. The other end of the elastic reset member 13 is connected to the tooth block 11. The elastic reset member 13 can be a spring. The tooth block 11 is slidably connected in the elastic groove 12, and the end of the tooth block 11 away from the elastic reset member 13 passes through the elastic groove 12. A roller is rotatably connected to the inclined surface of the tooth block 11 to reduce the frictional resistance between the tooth block 11 and the tooth plate 10 during relative movement.

[0042] Specifically, when the seedlings extend upwards, they will pull the travel seat 9 towards the seedlings. During the movement, the toothed block 11 is pressed by the inclined surface of the toothed plate 10, and the toothed block 11 compresses the elastic reset member 13 and moves into the elastic groove 12, so that the travel seat 9 can move normally towards the seedlings. Moreover, through the toothed block 11 meshing with the toothed plate 10, the toothed block 11 and the travel seat 9 cannot move backwards.

[0043] Reference Figure 1-9 The support unit also includes a return component installed on the travel seat 9. The return component includes return rods 15 symmetrically connected to the two side walls of the travel seat 9, and the return rods 15 are located directly below the toothed block 11. A return groove 16 is provided on the side wall of the toothed plate 10 near the travel seat 9 at the position corresponding to the return rod 15. The end of the return rod 15 away from the travel seat 9 extends movably into the return groove 16. The return groove 16 includes an upper groove 161, a lower inclined arc groove 162, a lower return groove 163 and an upper groove 164 connected in sequence. The upper groove 161 and the lower return groove 163 are arranged in parallel, and the lower inclined arc groove 162 is inclined. The length of the upper groove 161 is shorter than the length of the lower return groove 163.

[0044] Specifically, when the fixing device completes its task and no longer needs to provide auxiliary support for the seedling, the fixing device is removed from the seedling. When the slide 5 and the traveling seat 9 need to be returned to the starting point (farthest from the seedling's maximum value), a pushing force is applied to the slide 5 in the direction close to the seedling when it was supporting the seedling. The slide 5 drives the return rod 15 on the traveling seat 9 to first be in the upper groove 161 of the return groove 16. Then, the return rod 15 enters the lower return groove 163 through the lower inclined arc groove 162. During this stage, the upward pull component is stretched by force. Then, a pull force is applied to the slide 5 so that the return rod 15 reaches the connection point between the lower return groove 163 and the rising groove 164. Under the action of the upper pull component's reset force, the return rod 15 enters the upper groove 161 through the rising groove 164.

[0045] Reference Figure 1-8The pull-up assembly includes two pull rods 17 symmetrically connected to the upper end of the travel seat 9. Two pull-up slots 18 are symmetrically opened at the lower end of the slide 5. The end of the pull rod 17 away from the travel seat 9 extends movably into the corresponding pull-up slot 18. The pull rod 17 and the pull-up slot 18 are slidably connected. A pull-up reset member 19 is sleeved on the pull rod 17 located between the travel seat 9 and the slide 5. The pull-up reset member 19 can be a spring, and the two ends of the pull-up reset member 19 are respectively connected to the travel seat 9 and the slide 5.

[0046] Specifically, the slide block 5 and the traveling seat 9 are connected by the upper pull rod 17. When the slide block 5 is pushed horizontally, the upper pull rod 17 pulls the traveling seat 9 to move horizontally in sync. When the traveling seat 9 moves diagonally downward, that is, when the return rod 15 slides in the lower inclined arc groove 162, the traveling seat 9 pulls the upper pull rod 17 to move downward in the upper pull groove 18 and stretches the upper pull reset member 19. When the return rod 15 moves to the connection point of the lower return groove 163 and the rising groove 164, under the action of the deformation reset force of the upper pull reset member 19, the traveling seat 9 is pulled upward, so that the return rod 15 enters the upper groove 161 from the rising groove 164.

[0047] During use, the clamping block 2 on the support unit attached to the seedling is fixed by the fixing wire 1, so that the clamping block 2 and the seedling are fixed. When the seedling grows upward, the clamping block 2 moves upward. The clamping block 2 pulls the balance block 6 towards the seedling through the hinged transmission bar 7, and drives the slide 5 to slide on the slide rod 4. While the slide 5 moves towards the seedling, it drives the traveling seat 9 to move synchronously through the upward pull component. During the movement, the toothed block 11 is pressed by the inclined surface of the toothed plate 10. The toothed block 11 compresses the elastic reset member 13 and moves into the elastic groove 12, so that the traveling seat 9 can move normally towards the seedling. Moreover, through the toothed block 11 meshing with the toothed plate 10, the toothed block 11 and the traveling seat 9 cannot move backward, so that the traveling seat 9 and the slide 5 can move normally without affecting the upward extension of the seedling. When the seedling is blown by strong winds in severe weather, the multiple sets of support units distributed in a ring array not only provide good support and fixation for the seedling, but also provide good support and fixation for the seedling.

[0048] When it is necessary to return the slide 5 and the traveling seat 9 to the starting point, a pushing force is applied to the slide 5 in the direction of the seedling. The slide 5 drives the return rod 15 on the traveling seat 9 to first move in the upper groove 161 of the return groove 16. Then the return rod 15 enters the lower return groove 163 through the lower inclined arc groove 162. During this stage, the traveling seat 9 pulls the upper pull rod 17 downward in the upper pull groove 18 and stretches the upper pull reset member 19. Then, a pull force is applied to the slide 5 so that the return rod 15 reaches the connection point of the lower return groove 163 and the rising groove 164. Under the action of the deformation reset force of the upper pull reset member 19, the traveling seat 9 is pulled upward so that the return rod 15 enters the upper groove 161 from the rising groove 164.

[0049] Example 2, refer to Figure 5 and Figure 10 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that when supporting a seedling blown down by the wind, a support unit can be used alone in the direction of the seedling's fall. After the seedling is straightened, the clamping block 2 of the support unit is fixed together with the seedling by fixing steel wire. Since the toothed block 11 cannot move backward on the toothed plate 10 under normal circumstances, it is ensured that the support unit can support the fallen seedling.

[0050] Example 3, referring to Figure 1-8 This is the third embodiment of the present invention, which differs from the first embodiment in that: the support unit further includes a fertilization component installed inside the ground-mounted box 3. The fertilization component includes a bag-changing opening 20 at the bottom of the ground-mounted box 3 at the end away from the seedling. A matching bag-changing plate 21 is slidably connected inside the bag-changing opening 20. Multiple storage bags 22 containing nutrient solution are arranged at the bottom of the inner box of the ground-mounted box 3. The nutrient solution includes, but is not limited to, liquid fertilizer. A bag-removing opening is provided at the end of the ground-mounted box 3 near the seedling. A sealing plug 23 is inserted into the bag-removing opening. A bag-breaking needle 24 is connected to the end of the sealing plug 23 near the storage bag 22, and the other end of the bag-breaking needle 24 extends to the ground-mounted box 3. Inside the ground box 3, a liquid outlet is installed on the bottom of the ground box 3. The lower end of the traveling seat 9 is provided with a pusher assembly that pushes the liquid storage bag 22 to move. The liquid outlet includes a liquid outlet hole opened on the bottom of the ground box 3. A ball chamber 25 is connected to the liquid outlet hole with damping rotation. The lower end of the ball chamber 25 is connected to a liquid outlet pipe 26. The liquid outlet pipe 26 can drive the ball chamber 25 to rotate in the liquid outlet hole. During the seedling transplanting stage, the orientation of the liquid outlet pipe 26 is adjusted according to the position of the seedling roots so that the liquid outlet of the liquid outlet pipe 26 is close to the seedling roots before burying the soil. When the fixing device is removed, the plug 23 is taken out from the bag opening along with the bag breaking needle 24, and the liquid storage bag 22 on the bag breaking needle 24 is removed. It should be noted that the fertilization cycle of the fertilization component mainly occurs during the period after the seedlings are transplanted and re-rooted in the new soil. Therefore, not all of the multiple nutrient solution storage bags 22 in the ground box 3 will be used. The remaining unused storage bags 22 can be kept for the next use of the fixing device. Therefore, the push plate 14 and the bag-breaking needle 24 will not intersect. When it is necessary to reset the fixing device, first remove the fixing device from the seedling and pull it out of the soil. Then open the bag replacement plate 21, take out the remaining storage bags 22 after use, and then take out the plug 23 connected to the bag-breaking needle 24 from the ground box 3. At this time, the traveling seat 9 can move towards the direction where it was originally used to provide auxiliary support for the seedling, so that the sliding seat 5 and the traveling seat 9 return to the starting point.

[0051] Specifically, when the seedlings grow upwards, the travel seat 9 pushes the nutrient storage bag 22 towards the puncture needle 24 through the bag pushing component. The puncture needle 24 punctures the nutrient storage bag 22, and the nutrient solution in the nutrient storage bag 22 leaks out and is discharged through the outlet pipe 26 to fertilize the roots of the seedlings. During the seedling transplanting stage, the replacement plate 21 is opened first, the nutrient storage bag 22 is placed into the Adong ground-mounting box 3, and then the replacement plate 21 is slid into the replacement opening 20.

[0052] Reference Figure 1-8 The push bag assembly includes a long push slot 30 opened on the partition plate 8. Two compensation components are symmetrically installed on the side wall of the travel seat 9. The two compensation components pass through the push slot 30 and are jointly installed with a push plate 14. The push plate 14 movably abuts against the liquid storage bag 22 away from the seedling. The compensation component includes a compensation ring 27 connected to the side of the push plate 14 away from the liquid storage bag 22. A compensation rod 28 is movably passed through the compensation ring 27, and one end of the compensation rod 28 passes through the push slot 30 and is set on the side wall of the travel seat 9.

[0053] Specifically, when the travel seat 9 moves, it drives the compensation rod 28 to move synchronously within the push slot 30, and then pushes the push plate 14 to move synchronously through the compensation ring 27, thereby realizing the push of the liquid storage bag 22; when the travel seat 9 is adjusted in height, the compensation rod 28 moves vertically within the compensation ring 27, which does not affect the push of the push plate 14.

[0054] Reference Figure 5 The bag-breaking needle 24 has multiple petal-shaped bag-supporting pieces 29 evenly distributed in a ring on the needle wall near the needle tip; the bottom of the inner box of the ground box 3 near the liquid outlet is set as an inclined surface facing the liquid outlet, and the liquid storage bag 22 is tightly attached to the inner box wall of the ground box 3.

[0055] Specifically, the punctured storage bag 22 is opened by the support piece 29, allowing the nutrient solution inside the storage bag 22 to flow out and then be collected by the inclined surface of the inner bottom of the ground box 3.

[0056] During use, as the seedlings grow upwards, the traveling seat 9 drives the compensation rod 28 to move synchronously within the pushing slot 30, and then pushes the push plate 14 to move synchronously through the compensation ring 27, thereby pushing the liquid storage bag 22. The bag-breaking needle 24 punctures the liquid storage bag 22, and the bag-supporting plate 29 opens the punctured liquid storage bag 22 from the puncture opening, allowing the nutrient solution in the liquid storage bag 22 to flow out. Then, it flows through the inclined surface of the inner bottom of the ground box 3 to the liquid outlet pipe 26 and is discharged through the liquid outlet pipe 26 to fertilize the roots of the seedlings. The punctured liquid storage bag 22 remains on the bag-breaking needle 24.

[0057] Combining embodiments 1 and 3, the working principle of the present invention is as follows: The clamping block 2 on the support unit attached to the seedling is fixed by the fixing wire 1, so that the clamping block 2 and the seedling are fixed. When the seedling grows upward, the clamping block 2 moves upward. The clamping block 2 pulls the balance block 6 towards the seedling through the hinged transmission bar 7, and drives the slide 5 to slide on the slide rod 4. While the slide 5 moves towards the seedling, it drives the traveling seat 9 to move synchronously through the upward pull component. During the movement, after the toothed block 11 is pressured by the inclined surface of the toothed plate 10, the toothed block 11 compresses the elastic reset member 13 and moves into the elastic groove 12, so that the traveling seat 9 can move normally towards the seedling. Moreover, through the toothed block 11 meshing with the toothed plate 10, the toothed block 11 and the traveling seat 9 cannot move backward, so that the traveling seat 9 and the slide 5 can move normally without affecting the upward extension of the seedling. When the seedling is blown by strong winds in severe weather, the multiple sets of support units distributed in a ring array not only provide good support and fixation for the seedling, but also provide good support and fixation for the seedling.

[0058] When the traveling seat 9 moves towards the seedlings, it also drives the compensation rod 28 to move synchronously within the push slot 30, and then pushes the push plate 14 to move synchronously through the compensation ring 27, thereby pushing the liquid storage bag 22. The bag-breaking needle 24 punctures the liquid storage bag 22, and the bag-supporting plate 29 opens the punctured liquid storage bag 22 from the puncture opening, allowing the nutrient solution in the liquid storage bag 22 to flow out, and then flows through the inclined surface of the inner bottom of the ground box 3 to the liquid outlet pipe 26, and is discharged through the liquid outlet pipe 26 to fertilize the roots of the seedlings. The punctured liquid storage bag 22 remains on the bag-breaking needle 24.

[0059] When the fixing device completes its task and no longer needs to support the seedling, the fixing device is removed from the seedling. When the slide 5 and the traveling seat 9 need to be returned to the starting point, a pushing force is applied to the slide 5 in the direction of the seedling when it supports the seedling. The slide 5 drives the return rod 15 on the traveling seat 9 to first move in the upper groove 161 of the return groove 16. Then the return rod 15 enters the lower return groove 163 through the lower inclined arc groove 162. During this stage, the traveling seat 9 pulls the upper pull rod 17 downward in the upper pull groove 18 and stretches the upper pull reset member 19. Then, a pull force is applied to the slide 5 so that the return rod 15 reaches the connection point of the lower return groove 163 and the rising groove 164.
