Description

Technical Field

[0001] The present invention relates to the technical field related to pipe production, in particular to a production device for steel strip reinforced drainage pipes. Background Art

[0002] As is known, steel-reinforced drainage pipes use polyethylene as the inner and outer layer matrix material, and a steel-belt corrugated body coated with high-performance adhesive resin and bent into shape as the main supporting structure. They are wound and extruded into a whole spiral corrugated pipe on the production line. They combine the high stiffness and high strength of steel with the corrosion resistance, wear resistance and flexibility of plastic to make up for the low ring stiffness of larger diameter all-plastic buried drainage pipes.

[0003] The production line for steel-strip reinforced drainage pipes primarily involves galvanizing, cleaning, heating, gluing, cooling, and coiling the steel strip, as well as bending, steel-plastic lamination, and cooling. Each process requires corresponding equipment. During the lamination of the steel strip with the inner and outer layers of the substrate, a rolling mechanism is used to roll the inner and outer layers of the substrate onto the inner and outer surfaces of the steel strip to ensure strong adhesion between the inner and outer layers and the steel strip. Rolling is also performed at the junction of the inner and outer layers to ensure a strong bond.

[0004] When rolling the retroperitoneal tube, the rolling pressure must be ensured so that the inner and outer layer base materials can better adhere to the surface of the steel belt, especially during rolling at the base material seams. Therefore, it is necessary to always control the rolling pressure of each rolling wheel to be within the specified range. In the prior art, the rolling pressure of the rolling wheels is uniformly controlled and difficult to adjust individually. Due to wear during the operation of the rolling wheels or impurities adhering to the surface, some rolling wheels may have appropriate rolling pressure, while others may not, resulting in quality problems with the drainage pipe. Summary of the Invention

[0005] The purpose of the present invention is to provide a steel strip reinforced drainage pipe production device to solve the technical problems in the related art.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0007] A steel strip reinforced drainage pipe production device includes a rolling mechanism arranged on a foundation, the rolling mechanism rolls and compounds the base materials inside and outside the steel strip, the rolling mechanism includes an inner rolling module and an outer rolling module; the inner rolling module includes two rolling rollers arranged up and down, the rolling rollers roll and compound the base materials on the inner surface of the steel strip; the outer rolling module includes a first driving member corresponding to each rolling roller and a plurality of driving wheels coaxially arranged on the power output shaft of the first driving member, and each first driving member is also provided with a plurality of first rod bodies on the power output shaft, each driving wheel corresponds to a first rod body, one end of the first rod body is provided with a second driving member, and the other end is provided with a rolling wheel, and the rolling wheel rotates based on the power of the driving wheel at the corresponding position; when it is necessary to adjust the rolling force of the rolling wheel, the first rod body controls the distance between the rolling wheel and the corresponding rolling roller based on the power of the second driving member.

[0008] As mentioned above, a transmission wheel for transmitting power is provided between each of the driving wheels and the corresponding rolling wheel, and each of the first rod bodies is movably arranged on the power output shaft of the first driving member; a limiting slider is correspondingly installed on the rotating shaft of each of the rolling wheels, and each limiting slider is correspondingly slidably connected to a limiting slide rail, and the limiting slider is arranged to slide vertically on the corresponding limiting slide rail.

[0009] As mentioned above, the limiting slide rail includes: a pressure regulating section and a disassembly and assembly section; when the limiting slider slides in the pressure regulating section, the distance between the rolling wheel and the corresponding rolling roller changes to adjust the rolling force; when the limiting slider slides gradually away from the pressure regulating section in the disassembly and assembly section, the power transmission between the rolling wheel and the transmission wheel is gradually disconnected.

[0010] As mentioned above, the rotating shaft of the transmission wheel is connected to the corresponding driving wheel rotating shaft through the second rod body, and the rotating shaft of the transmission wheel is connected to the corresponding rolling wheel rotating shaft through the third rod body. The third rod body is a telescopic mechanism, and the telescopic movement of the third rod body is controlled by the third driving member. When the limiting slider slides in the pressure adjustment section, the third driving member does not control the telescopic change of the third rod body. When the limiting slider slides in the disassembly and assembly section, the third driving member controls the extension of the third rod body to disconnect the power of the rolling wheel from the corresponding transmission wheel.

[0011] As mentioned above, the end of the disassembly section away from the pressure regulating section is an open end.

[0012] As mentioned above, a shift block is provided on the first rod body. In the moving direction of the drain pipe, when one of the first rod bodies is driven by the second driving member to drive the rolling wheel to increase the rolling force, it drives the first rod body at the adjacent position to drive the rolling wheel to increase the rolling force through the shift block.

[0013] As mentioned above, in the opposite direction of movement of the drain pipe, when the limit slider moves from the pressure regulating section to the disassembly section, its corresponding first rod body gradually staggers with the shifting block on the adjacent first rod body.

[0014] The above-mentioned also includes a position switching mechanism provided between the outer rolling module and the base. When a certain rolling wheel is replaced, the position switching mechanism drives the outer rolling module as a whole to move along the moving direction of the drainage pipe; after the replacement of a certain rolling wheel is completed, the position switching mechanism drives the outer rolling module as a whole to move in the opposite direction of the movement of the drainage pipe; the moving distance of the outer rolling module when driven by the position switching mechanism is the same as the distance between the two driving wheels in adjacent positions.

[0015] As mentioned above, the position switching mechanism includes a slide groove provided on the base and a slide rod slidingly arranged in the slide groove. The slide rod is fixed to the external rolling module. When the limiting slider is at the end of the disassembly section away from the pressure adjustment section, the second driving member drives the external rolling module as a whole to move along the track of the slide groove.

[0016] As mentioned above, the slide groove includes a first vertical section, a second vertical section, a first inclined section and a second inclined section. The movement order of the slide rod in the slide groove is: from the first vertical section through the first inclined section to the second vertical section. During this stroke, the outer rolling module moves as a whole along the moving direction of the drain pipe; so that the second vertical section returns to the first vertical section through the second inclined section. During this stroke, the outer rolling module moves as a whole in the opposite direction of the movement of the drain pipe.

[0017] The beneficial effect of the present invention is that by individually adjusting the distance between each rolling wheel and the rolling roller at the corresponding position, the distance between each rolling wheel and the rolling roller at the corresponding position can be controlled within an appropriate range, thereby ensuring that the rolling force is appropriate and avoiding problems with the quality of the drainage pipe.

[0027] In order to make those skilled in the art better understand the technical solution of the present invention, Figure 1 To the attached Figure 6 The present invention is further described in detail.

[0028] An embodiment of the present invention provides a production device for a steel strip 10 reinforced drainage pipe, comprising a rolling mechanism provided on a base 1, wherein the rolling mechanism rolls and compounds the base material 11 on the inner and outer surfaces of the steel strip 10, and the rolling mechanism comprises an inner rolling module 2 and an outer rolling module 3; the inner rolling module 2 comprises two rolling rollers arranged one above the other, and the rolling rollers roll and compound the base material 11 on the inner surface of the steel strip 10; the outer rolling module 3 comprises a first driving member corresponding to each rolling roller and a plurality of driving wheels 30 coaxially arranged on the power output shaft of the first driving member, and each first driving member is further provided with a plurality of first rods 31 on the power output shaft, each driving wheel 30 corresponds to a first rod 31, and a second driving member 32 is provided at one end of the first rod 31, and a rolling wheel 33 is provided at the other end, and the rolling wheel 33 rotates based on the power of the driving wheel 30 at the corresponding position; when it is necessary to adjust the rolling force of the rolling wheel 33, the first rod 31 controls the distance between the rolling wheel 33 and the corresponding rolling roller based on the power of the second driving member 32.

[0029] Specifically, the foundation 1 is the supporting structure used in the production line of the steel strip 10 reinforced drainage pipe. For the convenience of subsequent description and understanding, the moving direction of the steel strip 10 reinforced drainage pipe after the steel strip 10 is composited with the inner and outer base materials 11 is horizontal, and the rolling direction of the steel strip 10 and the inner and outer base materials 11 by the rolling mechanism is vertical. In the prior art, an inner rolling module 2 and a matching outer rolling module 3 are provided for the rolling composite of the steel strip 10 and the inner and outer base materials 11. The inner rolling module 2 and the outer rolling module 3 adopt corresponding methods to roll the steel strip 10 and the inner and outer base materials 11 in the vertical direction. The outer base material 11 is rolled and compounded. Since the surface of the steel strip 10 reinforced drainage pipe is a smooth curved surface, the inner rolling module 2 includes two rolling rollers arranged upper and lower. The surface of the rolling roller is in contact with the inner base material 11 on the inner surface of the steel strip 10. Two positions parallel to the vertical diameter are selected and a rolling roller is arranged at each position. Then, a number of rolling wheels 33 will be set on the outer wall of the steel strip 10 corresponding to each rolling roller. The rolling wheels 33 are arranged in sequence along the horizontal direction, and their overall length is less than the length of the corresponding rolling roller. Now, a number of rolling wheels 33 corresponding to the rolling roller located vertically above are selected as an example and described in detail.

[0030] The position of the rolling roller is basically unchanged, and the adjustment of the rolling force is basically achieved by adjusting the distance between the rolling wheel 33 and the rolling roller. The rolling position of the rolling wheel 33 is the inner and outer base materials 11 at the gap of the columnar spiral structure steel belt 10, and this position is also the joint of the base material 11 that is columnarly spirally compounded on the inner and outer surfaces of the steel belt 10. Therefore, it is necessary to control the rolling force to make the composite effect of the steel belt 10 and the base material 11 better in order to extend the service life. For example, the rolling force range is between 12 and 18 units of force. If it exceeds the force, it will cause excessive rolling, making the base material 11 at the pressed position thinner. If it is lower than the force, it will cause insufficient rolling force, and the composite effect of the inner and outer base materials 11 will deteriorate. In the prior art, the rolling force of the rolling wheel 33 is uniformly controlled and difficult to adjust individually. Due to wear of the rolling wheel 33 during operation or impurities adhering to the surface, some rolling wheels 33 have appropriate rolling force, while others have inappropriate rolling force, resulting in quality problems of the drainage pipe.

[0031] Therefore, in this embodiment, each rolling wheel 33 is individually adjusted in rolling force, that is, a plurality of driving wheels 30 are coaxially arranged on the power output shaft of the first driving member, the first driving member can be a motor, not shown in the figure, and the plurality of driving wheels 30 are coaxially arranged, so the position of each driving wheel 30 cannot be adjusted individually, and then a first rod body 31 is correspondingly provided for each driving wheel 30, and a second driving member 32 is provided at one end of the first rod body 31, and the second driving member 32 is preferably a hydraulic cylinder, and a rolling wheel 33 is provided at the other end of the first rod body 31. The rolling wheel 33 rotates based on the friction of the driving wheel 30 at the corresponding position, and the distance between the rolling wheel 33 and the rolling roller can be controlled by the expansion and contraction change of the second driving member 32 The first rod 31 is driven by the first rod 31, and the power output shaft of the first driving member is the swing axis. That is, the rolling wheel 33 moves with the corresponding central axis of the driving wheel 30 as the swing axis, and the rolling wheel 33 itself rotates under the friction of the corresponding driving wheel 30, thereby realizing the rolling and compounding of the steel strip 10 and the base material 11. A pressure sensor is set at the position where each rolling wheel 33 is connected to the first rod 31 (this is the existing technology and will not be repeated, and is not shown in the figure). The pressure sensor is used to monitor the change in the rolling pressure of the rolling wheel 33. The second driving member 32 is based on the monitoring signal of the pressure sensor, and controls the change in the distance between the rolling wheel 33 and the rolling roller through the first rod 31.

[0032] The beneficial effect of this embodiment is that by individually adjusting the distance between each rolling wheel 33 and the rolling roller at the corresponding position, the distance between each rolling wheel 33 and the rolling roller at the corresponding position can be controlled within an appropriate range, thereby ensuring that the rolling force is appropriate and avoiding problems with the quality of the drainage pipe.

[0033] Furthermore, a transmission wheel 34 for transmitting power is provided between each of the driving wheels 30 and the corresponding rolling wheel 33, and each of the first rod bodies 31 is movably arranged on the power output shaft of the first driving member; a limiting slider 35 is correspondingly installed on the rotating shaft of each of the rolling wheels 33, and each limiting slider 35 is correspondingly slidably connected to a limiting slide rail 36, and the limiting slider 35 is arranged to slide vertically on the corresponding limiting slide rail 36.

[0034] Specifically, in the aforementioned embodiment, although the distance change between the rolling wheel 33 and the rolling roller is controlled to adjust the rolling force, the moving trajectory of the rolling wheel 33 is arc-shaped when it approaches or moves away from the rolling roller. In this way, the rolling forces applied by the rolling wheel 33 and the rolling roller to the steel strip 10 and the base material 11 are difficult to basically overlap in the vertical direction, that is, the rolling points of the two overlap in the upper vertical direction, which has an adverse effect on the rolling composite effect of the steel strip 10 and the base material 11.

[0035] Therefore, in this embodiment, the moving direction of the rolling wheel 33 is limited, that is, initially, the rolling wheel 33 applies a vertical downward force to the steel strip 10 and the base material 11, and the rolling roller applies a vertical upward force to the steel strip 10 and the base material 11. The limiting slider 35 moves vertically on the limiting slide rail 36, and the moving direction of the rolling wheel 33 connected to the limiting slider 35 is limited, so the rolling force direction applied by the rolling wheel 33 and the rolling roller to the steel strip 10 and the base material 11 coincides vertically. Among them, when the second driving member 32 drives the rolling wheel 33 to move through the first rod body 31, the distance between the rolling wheel 33 and the corresponding driving wheel 30 will definitely change, so the transmission between the two is transmitted by the transmission wheel 34, and the transmission The position change of the wheel 34 can be achieved by setting a separate driving source. If the distance between the rolling wheel 33 and the corresponding driving wheel 30 changes, the first rod body 31 and the power output shaft of the first driving member should also be movably connected, that is, relative rotation and relative sliding can occur between the two. In this way, a long sliding mouth 37 can be opened on the first rod body 31, and the sliding mouth 37 is movably connected to the power output shaft of the first driving member, and the second driving member 32 is hinged to the base 1 and also hinged to the first rod body 31. In this way, the moving direction of the rolling wheel 33 is limited, and the power transmission between the rolling wheel 33 and the corresponding driving wheel 30 can still proceed smoothly, so that the rolling composite effect between the steel strip 10 and the base material 11 is effectively improved.

[0036] Preferably, the limiting slide rail 36 includes: a pressure regulating section 360 and a disassembly section 361; when the limiting slider 35 slides in the pressure regulating section 360, the distance between the rolling wheel 33 and the corresponding rolling roller changes to adjust the rolling force; when the limiting slider 35 slides gradually away from the pressure regulating section 360 along the disassembly section 361, the power transmission between the rolling wheel 33 and the transmission wheel 34 is gradually disconnected.

[0037] Specifically, the rolling wheel 33 will wear out during use, and the steel strip 10 will be heated before being compounded with the base material 11. The base material 11 is also extruded, so some base material 11 will adhere to the surface of the rolling wheel 33. When the second driving member 32 adjusts the distance between the rolling wheel 33 and the rolling roller through the first rod body 31, if the moving distance of the rolling wheel 33 is still not enough to provide a suitable rolling pressure, or if the rolling pressure alternates between large and small, then the rolling wheel 33 needs to be replaced.

[0038] When the roller 33 is in the state of being pressed down, the second driving member 32 can be used to drive the roller 33 to move upward from the pressure regulating section 360 to the disassembly section 361 through the first rod body 31. During this process, the distance between the roller 33 and the rolling roller gradually increases, and the distance between the roller 33 and the corresponding driving wheel 30 also increases. Then, the end of the first rod body 31 connected to the second driving member 32 will move closer to the position of the driving wheel 30 while swinging downward. When the limiting slider 35 reaches the end of the disassembly section 361 away from the pressure regulating section 360, the roller 33 can be replaced. At this time, the power transmission between the roller 33 and the driving wheel 30 should be disconnected, that is, the transmission wheel 34 can be separated from the roller 33 by a separately set driving source control, which makes it easier to replace the roller 33.

[0039] The power transmission between the rolling wheel 33 and the driving wheel 30 can be disconnected not only by actively controlling the transmission wheel 34 to be separated from the rolling wheel 33, but also by a passive method. That is, in a preferred embodiment, the rotating shaft of the transmission wheel 34 is connected to the rotating shaft of the corresponding driving wheel 30 through a second rod 38, the second rod 38 does not have a telescopic function, and one end of the second rod 38 is rotatably connected to the rotating shaft of the transmission wheel 34, and the other end is rotatably connected to the rotating shaft of the driving wheel 30, the rotating shaft of the transmission wheel 34 is connected to the rotating shaft of the corresponding rolling wheel 33 through a third rod 39, and the third rod 39 is connected to the rotating shaft of the driving wheel 30. 9 is a telescopic mechanism, one end of the third rod 39 is rotatably connected to the rotating shaft of the rolling wheel 33, and the other end is rotatably connected to the rotating shaft of the transmission wheel 34. The third rod 39 is controlled to be telescopic by the third driving member, that is, the third rod 39 includes a first section connected to the rolling wheel 33 and a second section connected to the transmission wheel 34. The second section is fixedly connected to the limiting rod 40. Correspondingly, a limiting groove 41 is provided on the first rod 31. The limiting groove 41 includes an arc segment 410 whose center is on the central axis of the rolling wheel 33, and a straight line segment 411 parallel to the length direction of the first rod 31. When the limiting slider 35 is in the pressure When sliding in the force adjustment section 360, the third driving member does not control the extension and contraction of the third rod 39, that is, at this time the limit rod 40 is in the arc section 410 at the corresponding position, and the length of the third rod 39 cannot change. Then the transmission wheel 34 moves under the drive of the second rod 38 and the third rod 39, and maintains rolling friction contact with the driving wheel 30 and the transmission wheel 34. Because when the second rod 38 and the third rod 39 cannot change in length, the two form a V-shaped connecting rod structure, and the distance change between the driving wheel 30 and the rolling wheel 33 must be driven by the V-shaped connecting rod structure. The transmission wheel 34 at the rotating shaft changes position to ensure that the transmission wheel 34 can maintain power transmission. When the limit slider 35 slides in the disassembly and assembly section 361, that is, when sliding in the direction away from the pressure adjustment section 360, the limit rod 40 will gradually enter the straight section 411 from the arc section 410, and then slide in the straight section 411. When the limit rod 40 slides in the straight section 411, the extension of the third rod body 39 will no longer be restricted. Then, as the rolling wheel 33 gradually moves away from the driving wheel 30, the rolling wheel 33 and the transmission wheel 34 will gradually separate, thereby realizing the disconnection of power transmission.

[0040] Preferably, the end of the disassembly section 361 away from the pressure regulating section 360 is an open end; specifically, after the limiting slider 35 reaches the end of the disassembly section 361 away from the pressure regulating section 360, the open section is more convenient for disassembly and assembly of the rolling wheel 33.

[0041] Furthermore, a shift block 42 is provided on the first rod body 31. In the moving direction of the drain pipe, when one of the first rod bodies 31 is driven by the second driving member 32 to drive the rolling wheel 33 to increase the rolling force, the shift block 42 drives the first rod body 31 at the adjacent position to drive the rolling wheel 33 to increase the rolling force.

[0042] Specifically, when the rolling force of one of the rolling wheels 33 for compounding the steel strip 10 and the base material 11 needs to be adjusted, there will inevitably be a period of time when the compounding effect between the steel strip 10 and the base material 11 becomes worse, especially when the rolling force of a certain rolling wheel 33 becomes smaller. Therefore, in this embodiment, when the rolling force of one of the rolling wheels 33 becomes smaller, the corresponding second driving member 32 adjusts the distance between it and the rolling roller through the first rod 31 to shorten. Because the rolling force has a suitable range, that is, the rolling force range mentioned in the aforementioned embodiment is between 12 and 18 units of force. Under normal conditions, it is better for the rolling force to be in the middle value. Therefore, when the rolling force needs to be adjusted, When the rolling force of the rolling wheel 33 with a pressure degree is adjusted to 12, the first rod 31 corresponding to the rolling wheel 33 will drive the shift block 42 connected thereto to shift the first rod 31 at the adjacent position to swing. The first rod 31 at the adjacent position is along the moving direction of the drain pipe, and the rolling force of the rolling wheel 33 at the adjacent position will be closer to 18 units of force from 15 units of force, that is, the rolling force is increased to pressurize and roll the parts of the steel strip 10 and the base material 11 that have not been rolled into place by the adjusted rolling wheel 33, so as to ensure that during the manufacturing process of the drain pipe, the rolling effect between all parts of the steel strip 10 and the base material 11 can be kept within a relatively even range.

[0043] The arrangement position of the shift block 42 cannot hinder the downward swing of the first rod body 31 at the adjacent position in the opposite direction of movement of the drain pipe. That is, in the opposite direction of movement of the drain pipe, when the limit slider 35 enters the disassembly section 361 from the pressure adjustment section 360, its corresponding first rod body 31 gradually staggers with the shift block 42 on the first rod body 31 at the adjacent position.

[0044] Furthermore, it also includes a position switching mechanism provided between the outer rolling module 3 and the base 1. When a certain rolling wheel 33 is replaced, the position switching mechanism drives the outer rolling module 3 as a whole to move along the moving direction of the drain pipe; after the replacement of a certain rolling wheel 33 is completed, the position switching mechanism drives the outer rolling module 3 as a whole to move in the opposite direction of the movement of the drain pipe; the moving distance of the outer rolling module 3 when driven by the position switching mechanism is the same as the distance between the two driving wheels 30 in adjacent positions.

[0045] Specifically, the number of rolling wheels 33 represents the number of times any point of the steel strip 10 and the base material 11 is rolled. Since there are two rolling rollers, the corresponding rolling wheels 33 should also be divided into two groups. In this way, when one of the rolling wheels 33 is replaced, it is equivalent to one less rolling number of a certain point of the steel strip 10 and the base material 11, which will inevitably lead to the problem of poor rolling composite effect of a certain part between the steel strip 10 and the base material 11.

[0046] Therefore, in order to better solve the above problems, in this embodiment, the outer rolling module 3 is movably arranged on the base 1, and its position can be changed, that is, the position switching mechanism includes a slide groove 43 provided on the base 1 and a slide rod 44 slidingly arranged in the slide groove 43, the slide rod 44 is fixed to the outer rolling module 3, and when the limiting slider 35 is at the end of the disassembly section 361 away from the pressure adjustment section 360, the second driving member 32 drives the outer rolling module 3 to move along the track of the slide groove 43 as a whole, wherein the slide groove 43 includes a first vertical section 430, a second vertical section 431, a first inclined section 432 and a second inclined section 433, and the movement order of the slide rod 44 in the slide groove 43 is: from the first vertical section 430 through the first inclined section 432 After the second vertical section 431 is entered, the outer rolling module 3 moves along the moving direction of the drain pipe as a whole. A stopper 434 is provided at the hinged joint between the first vertical section 430 and the first inclined section 432, and a first elastic member is provided at the hinged joint. When the stopper 434 is pressed, the depth of the first vertical section 430 is consistent with the depth of the first inclined section 432. When the slide bar 44 enters the first vertical section 430, the stopper 434 is squeezed out by the slide bar 44, and the second driving member 32 is shortened. The outer rolling module 3 uses gravity to drive the slide bar 44 to slide along the inclined direction of the first inclined section 432 into the second vertical section 431. The depth of the second vertical section 431 is greater than the depth of the first inclined section 432, and the slide bar 44 enters the second vertical section 431. After the vertical section 431, it is impossible to reverse into the first inclined section 432. The lowest point height of the first vertical section 430 is the same as that of the second vertical section 431, that is, the position where the rolling wheel 33 rolls the steel strip 10 and the base material 11; thus, the second vertical section 431 returns to the first vertical section 430 through the second inclined section 433. During this stroke, the outer rolling module 3 moves as a whole in the opposite direction of the movement of the drain pipe. The depth of the second vertical section 431 is less than the depth of the second inclined section 433. The sliding rod 44 moves up along the second vertical section 431 and enters the second inclined section 433. A swing rod 435 is hinged at the junction of the second inclined section 433 and the first inclined section 432, and a second elastic member is provided at the hinge. Under the elastic force of the second elastic member, the swing rod The rod 435 always has a tendency to hinder the connection between the first inclined section 432 and the second inclined section 433, that is, when the slide bar 44 reaches the junction of the first inclined section 432 from the first vertical section 430, if it continues to move upward, it will be hindered by the rocker bar 435, and during the process of the outer rolling module 3 driving the slide bar 44 to move along the second inclined section 433 under the action of gravity, the slide bar 44 will push the rocker bar 435 to swing, so that the rocker bar 435 first squeezes the stopper 434, and the wedge-shaped cooperation between the rocker bar 435 and the stopper 434 realizes the squeezing action, so that the depth of the first vertical section 430 is consistent with the depth of the first inclined section 432, and the rocker bar 435 blocks the entrance of the second inclined section 433, so that the slide bar 44 can smoothly return to the first vertical section 430.
