Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention provides flexible hoses for various fluids such as joint pipes, on-off valves, and other equipment ports. Concerning improvement of a hose band that is semi-permanently connected and fixed to a metal part.

0002

[Conventional technology]

A large number of engagement holes are punched into the main body of the band, which is made of stainless steel or other metal strips. Then, the main body of the band is rolled up into a circular ring shape to make it three-dimensional. By artificially forcibly contracting and deforming the diameter of the hose, the hose is placed in a so-called choked state. For hose bands that are fixed to In addition to functioning as an ohm wheel, a mounting hole is attached to the circumferential surface of the main band. The operation screw rod held through the ring is used as a worm, and the screw is the main body of the band. By engaging the engagement hole of the band and rotating the threaded rod, the diameter of the band main body can be changed. , and a dovetail-shaped ear piece is connected in advance from the circumferential surface of the main body of the band. By holding the ear overhang and squeezing the ear at the same time, you can Two types are known: one that shrinks the diameter of the main body.

0003

[Problem that the idea aims to solve]

However, in the former case, the operating screw rod is located on the circumferential surface of the main band, and the mounting housing Since these are held through the band, they do not protrude bulkily from the main body of the band. As a result, equipment such as hoses, their joints, on-off valves, etc. may undergo rotational movement. In some cases, it is difficult to adopt this type of material because it will interfere with its rotational movement. As a hose band that is used in large quantities, it is significantly heavier and maximizes the mass production effect. There are some problems that cannot be expected.

0004 On the other hand, in the latter case, the dovetail-shaped ear piece is attached to the main band using tools such as pliers. Since it is crushed tightly against the circumferential surface, there is no risk of it becoming bulky as mentioned above, but the The amount of constriction on the ear piece is not set to the relevant dimension that corresponds correctly to the thickness of the hose. If it is not used semi-permanently, there will be excess or deficiency in the diameter contraction force of the band itself. As a hose band, it still lacks durability and stability due to the fixed state of the hose. .

[0005] In this respect, in the latter form, there are many locking claws on the circumferential surface of the main band, and By correspondingly distributing the receiving and meshing holes, a circular ring can be created according to the thickness of the hose. There are also some that have been devised so that the diameter of the winding can be adjusted. However, even with this, the above-mentioned dovetail-shaped lug has a final At this stage, the squeezing operation is performed using pliers, etc., so problems such as those mentioned above may occur. There is no doubt that there is a risk of problems arising.

[0006] Therefore, in order to overcome the above-mentioned problems, the present inventor first applied No. 3-34310 was proposed, but as a result of continued intensive research, this It has been found that the following problems still need to be improved in both of the earlier patent designs.

[0007] In other words, in the former hose band, due to its configuration, the main body of the band (11) is wound. The locking claw (14) and the operating ear (16) are both bent outward at an acute angle from one end side. At the same time, another operating ear (2) is attached from the other end of the band body (11). 3) are also bent outward at an acute angle, so these are attached to the hose (10). In the tightened state of use, the hose (10) still protrudes bulky, especially the hose (10). When equipment such as a pipe, its joint pipe, or an on-off valve rotates, the rotational movement must be supported. Do not do so as there is no risk of injury.

[0008] Also, a tension operation tool (for pushing open the pair of operation ears (16) and (23)) 25) is also a special case in which the pair of working claws (26) and (27) are different from each other. The beak-shaped working claw (26) is rolled up and the operating ear (1 6), turn the remaining operating claw (27) and attach it to the other operating lug (23) on the other end. It is necessary to lock it correspondingly and push it open, so it is difficult to distinguish between However, it is still inconvenient for workers.

[0009] On the other hand, in the latter hose band, due to its configuration, the main body of the band (11) is bent. The locking claw (16) and tongue piece (14) are slightly bent outward at an acute angle from the end side. At the same time, the operating ear (25) is also inserted from the other end of the band main body (11). However, it is still bent outward at an acute angle. Also, in the tension operation tool (B) The pair of working claws (27) and (28) also have different amounts of protrusion. So Therefore, there is still a risk that the former problem mentioned above may occur.

0010

[Means to solve the problem]

In order to improve this problem, this invention has a fixed size for the hose band structure. The main body of the band is made of a metal strip cut into pieces, with one end and the other partially It is rolled up into a circular ring shape that will be circumscribed and made into a three-dimensional shape, and its diameter is artificially forced. A hose band that secures a hose in a neck tightening state by shrinking and deforming. A first convex channel wall that protrudes outward is provided at the tip of one end of the winding. and a tool receiving opening by which an opening edge is defined. A backing tongue narrower than the band body itself extends from the flannel wall, and also In the middle of one end of the winding, there is a tool escape port adjacent to the tool receiving port mentioned above. A second convex channel wall, which is also raised outward, is connected to the long window, which is more elongated than this. On the other hand, at the tip of the other end of the above-mentioned winding, there is a hole that sinks into the long window. receiving the concave channel wall and the second convex channel wall adjacent thereto; A fixed claw is provided from the center of the concave channel wall toward the receiving port. At the same time, in the middle of the other end of the winding, there is a part that extends outward. A tool recess adjacent to the receiving port via a raised third convex channel wall. mouth and its tool recess through a fourth convex channel wall that also bulges outwards. The opening of the opening and the adjacent long window are distributed, and the backing tongue piece is attached to the fourth convex channel wall. By inserting the backing into the bead groove and engaging it, the main body of the band can be Wrap it into a circular ring shape with one end circumscribing the other end. In addition to specifying that it can be made three-dimensional, the diameter of the main band is artificially contracted and changed. When shaped, the second convex channel wall on one end of the above-mentioned winding and the concave channel wall on the other end The fixed claws protruding from the shaped channel wall are arranged so that they bite and lock each other. It is characterized by the fact that

[0011]

[Effect]

According to the above configuration of the present invention, the backing extends from one end of the band main body when it is rolled up. Place the tongue piece in the bead groove of the fourth convex channel wall, which is also formed in the middle of the other end. By inserting and engaging the backing state, the main body of the band can be rolled up and It can be rolled up into a circular ring shape with the other end circumscribing one end to create a three-dimensional shape. I can do that.

0012 Temporary fixing to a hose where one end of the above-mentioned band is crossed with the other end. In the fitted state, the first convex tip forming the opening edge of the tool receiving opening on one end side The channel wall, the tool relief port on the other end side, and the second convex channel wall receiving port. The partitioning third convex channel wall is juxtaposed in the left-right positional relationship, and It spans both the tool receiving port and tool relief port that open on one end side, and the other end side. The tool escape port will be in communication.

[0013] Therefore, the tool receiver at one end is inserted through the tool relief opening at the other end of the bend. Insert the operating claw of the expansion operation tool from the outside into the opening or tool escape opening to perform the operation. The claws force one end and the other end of the band to move in opposite left and right directions. By pushing it open, the diameter of the main body of the circular ring-shaped band can be contracted and deformed. .

[0014] As a result, the hose band of the present invention can protect the hose from its joint pipes, on-off valves, etc. It will be connected and fixed to the base of other equipment in a so-called neck tightening state, but In the fixed state, the second convex channel wall protrudes from one end of the main body of the band. and a fixed claw protruding from the concave channel wall at the other end. Due to the locking action, the lock is kept extremely stable, and the hose band Because it is extremely flat as a whole, in the unlikely event that it is exposed to external forces such as vibration or impact during use. Even if the above-mentioned joint pipe or other equipment is subject to rotational movement, never There is no risk of relaxation or dissociation.

[0015]

【Example】

Hereinafter, the specific configuration of the present invention will be described in detail based on the illustrated embodiment. Figures 3 to 7 show the unfolded flat plate state (material processing state) of the hose band in Figures 3 to 7. Each item is shown in its usage state as a finished product by three-dimensionalization, and its hose band As for the material of Stainless steel (e.g. SUS304) or other metal strips (approximately 7 mm) M) is used, and depending on the thickness of the desired hose (10) from the long length in advance, Then, it will be cut to an appropriate size.

[0016] (11) is a circular shape in front view from the strip material (M) cut to a certain size. By winding it into a ring shape and making it three-dimensional, the tightening action of the hose (10) is improved. It is mainly a band that serves directly, so to speak, and there is also a band on one end of the winding (11a). They partially overlap by a certain amount (L) so that the other end side (11b) is circumscribed. ing. Needless to say, the band main body (11) has a certain width of the band material (M) itself. (W), and a tool receiving opening (12 ) is punched out into a rectangular shape in plan view. The opening width of the tool receiving port (12) ( W1) is approximately 3.5 to 4 in correlation with the above constant width (W) (approximately 7 mm). Dimensions are in mm.

[0017] In that case, the one end side (11a) of the band main body (11) is cut off. The tip is formed as a backing tongue (13) with a narrow constant width (W2) of approximately 3 mm. It is continuously extended by a certain length (F) (approximately 7 mm). Moreover, the above A reinforcing bead is provided at the root portion bordering the tool receiving port (12). Therefore, the base of the backing tongue (13) is approximately equal to the thickness (T) of the strip material (M). Even if it is shaped as a first convex channel wall (14) that bulges outward by the same amount. There is.

[0018] In other words, the circumferential direction of the band main body (11) at the tool receiving opening (12) The opening edge (one side of the above square) perpendicular to (the longitudinal direction of the strip material) 1 convex channel wall (14); The wall (14) is expanded from the outside to receive the expansion operation tool described later. The operating tool can be locked securely and stably.

[0019] (15) and (16) are similarly located in the middle of one end of the winding (11a), Tool reliefs whose openings are distributed sequentially in parallel from the tool receiving port (12) It has an entrance and a long window, both of which have the same opening width (W1) of approximately 4mm. , while the former has an almost square shape in plan view, the latter is much larger than this. The hose band extends in the form of a long hole, contributing to the weight reduction of the hose band itself.

[0020] In addition, (17) is a second protrusion that partitions the tool escape opening (15) and the long window (16). shaped channel wall, again by an amount approximately equal to the thickness (T) of the strip material (M) It is raised outward, and a fixing claw on the other end of the bend (11b), which will be described later, is attached here. It has a biting and locking effect.

[0021] Next, (18) is a band that will be circumscribed on the one end side (11a) of the above-mentioned winding. the second convex channel punched on the other end (11b) of the main body (11); It is a receiving opening in the wall (17), which has a rectangular shape in plan view, and its opening. The mouth width (W1) is also sized to about 4 mm. Then, bend the other end side (1 The cutting tip of 1b) is inward by an amount approximately equal to the thickness (T) of the strip material (M). It is shaped as a concave channel wall (19) that collapses when the channel is closed.

[0022] That is, the buffer at the receiving opening (18) of the second convex channel wall (17) is The opening edge (upper one side of the rectangle) is defined by its concave channel wall (19). That's it.

[0023] Moreover, from the center of the concave channel wall (19), there is a narrow constant width of about 3 mm. A fixed claw (20) having a width (W2) extends toward the inside of the receiving opening (18). The fixed claw (20) has a sharp point. The tip end is a second convex channel wall (17) for pawl locking on the one end side (11a) ), it is designed to bite and lock as if it were to sink down on its own. Furthermore, its fixation The tip of the claw (20) has a convex arc or triangular shape in plan view.

[0024] Also, (21) and (22) are similarly located in the middle of the other end of the winding (11b). The openings are arranged in series and in parallel from the second convex channel wall receiving opening (18). It has a distributed tool escape port and a long window, both of which have the same opening width of approximately 4 mm ( W1). In that case, the former tool escape port (21) is It is considerably longer and narrower than the tool escape opening (15) on the one end side (11a), and its fixed claw ( 20) and attach it to the second convex channel wall (17) on one end side (11a). In the locked state, the tool escape opening (1 5) and the tool receiving port (12). ing.

[0025] Then, the tool escape opening (21) on the other end side (11b) of the winding and the above-mentioned The thickness of the channel wall receiving opening (18) is approximately the same as the thickness (T) of the strip material (M). It is separated by a third convex channel wall (23) which is raised outwardly. So Therefore, this third convex channel wall (23) is rolled up and the one end side (11a) is Like the first convex channel wall (14), it functions to receive the expansion operation tool. The expansion operation tool should be stably and securely locked here from the outside while I can do it.

[0026] On the other hand, the long window (22) on the other end side (11b) is also on the one end side of the above-mentioned bending. (11a) and the long window (16), the opening is extended so as to form a left-right symmetrical form. This and the tool escape opening (21) are separated by a fourth convex channel wall (2 4). The fourth convex channel wall (24) is It corresponds to the backing tongue piece (13) on one end side (11a) of the barb, and has a certain length (F). By applying a reinforcing bead, a backing tongue (13) is inserted into the bead groove. is now able to accept. This allows for an overall flush condition. This means that they overlap.

[0027] The amount of outward protrusion of the fourth convex channel wall (24) is also made of the strip material (M). It is almost equal to the thickness (T) of . In addition, the tool receiving port (12) and tool escape port (15) (21), long windows (16) (22), second convex channel wall receiving opening ( 18) The opening width (W1) is determined by the material thickness (T) at both left and right ends of the strip material (M). As long as a dimensional width equivalent to at least 1.5 times of The hose band itself can be made lighter by forming the hose band. .

[0028] The hose band with the above structure is made of metal strip (M) and is made of the following material: It can be mass-produced according to the following. That is, the long strip material (M) is automatically and intermittently In the process of transferring the tongue piece (13) to and the cutout in which the fixing pawl (20) is to be contoured, and the tool receiving opening (12) and the second Convex channel wall (17) receiving port (18), tool relief port (15) (2 1) and punching out the long windows (16) and (22) are performed all at once. Its punched shape The state is as shown in FIGS. 8 to 10.

[0029] Next, the strip material (M) is passed through a press mold (not shown) to form the shape shown in FIG. As suggested from the processing state, the first to fourth convex channel walls (14) (17) ( 23) (24) and the concave channel wall (19) are done all at once. Ru. In that case, a second convex channel is formed from the center of the concave channel wall (19). The fixed claw (20) that protrudes toward the receiving opening (18) of the wall (17) is also The concave channel remains in the shape of a convex arc or a triangle in a plan view that was previously punched. It can be recessed into a continuous integral part with the flannel wall (19).

[0030] After that, the strip material (M) is cut off from the position indicated by the symbols (K-K) in Figures 8 to 11. Cut the main body of the band (11) to the specified size into a frame (not shown). The ohming machine continues to produce a constant amount (L) as suggested by the dashed line in Figure 2. It is rolled up into a circular ring shape that overlaps only to create a three-dimensional shape. It is completed as a product. In addition, the code (A) in FIGS. 8 to 11 indicates the above-mentioned punching die. and suggests the required size of the press processing die.

[0031] In addition, a long window (16) is punched on one end (11a) of the band main body (11). ) and the long window (22) punched on the other end (11b) of the same bending (S) is changed in length by controlling the transfer speed of the strip material (M), etc. By doing this, we can provide a wide variety of hose bands depending on the thickness of the desired hose (10). , can be manufactured very easily. When manufacturing such a wide variety of products, the above-mentioned There is no need to modify the punching mold or the press mold. Excellent in adaptability and mass production.

[0032] Using the hose band of the present invention, the hose (10) can be attached to its joint pipe, on-off valve, etc. When connecting and fixing the base part (25) of another device, the main body of the band (11 ) around the hose (10) in a temporary manner as suggested by the chain line in Figure 2. Let's go. The wrapping operation involves wrapping the hose (10) in the middle of the longitudinal direction. Of course, you can do it as you like.

[0033] That is, with respect to one end (11a) of the band main body (11), the other end is The one end side (11b) of the rolled side (11b) is partially circumscribed. a) with a backing tongue (13) of narrow constant width (W2) extending from Into the bead groove of the fourth convex channel wall (24) located corresponding to the end side (11b), It lets them escape from the other side.

[0034] In this case, the first convex channel wall ( 14) is a tool escape opening (21) that opens at the other end of the winding (11b). While engaged, it will be rolled up under its movement guiding action, so its operation is difficult. In addition to being able to perform the work extremely smoothly, the main body of the band (11) can be 1a) and the other end (11b) are maintained in an accurate overlapping state without lateral deviation. It is.

[0035] Then, one end (11a) of the band main body (11) and the other end (11a) of the band main body (11) are rolled up. 1b) is crossed to the hose (10), one end side (11 a) a first convex channel wall forming an opening edge of the tool receiving opening (12); (14), the tool escape opening (21) and the second convex chia on the other end side (11b) The third convex channel wall (23) that partitions the channel wall receiving opening (18) Since they are arranged in parallel based on the right positional relationship, the first convex channel wall (14) and the third convex channel wall For the shaped channel wall (23), perform a plier type expansion operation as shown in Figures 12 and 13. Since the pair of left and right working claws (26) provided at the tip of the tool (B) are respectively locked, be.

[0036] The pair of left and right working claws (26) of the expansion operation tool (B) are the same. Each of the above-mentioned tools has an opening at one end (11a) of the band main body (11) when the band is bent. There is a receiving opening (12) and a tool escape opening (2) which also opens at the other end (11b). 1) is formed in a size that allows it to be taken in and taken out. (27) is the double action claw (26). It is an opening/closing pivot, and when the left and right pair of handles (28) are closed, the dual action claws (26 ) will act to expand using its pivot (27) as a fulcrum. (29) is both hands This is a spring material interposed and connected between the dollars (28).

[0037] Therefore, the dual-action claw (26) of such an expansion operation tool (B) is used as a band main body ( Similarly to the tool receiving opening (12) on the one end side (11a) of the winding in 11). While inserting both into the tool escape opening (21) on the other end side (11b), (26) to the first convex channel wall (14) and the third convex channel wall (23); After locking each as shown in Figure 14, pull the handle (28) of the operating tool (B). With the double action claw (26), the band main body (11) is rolled up on one end side. (11a) and the other end (11b) are forced in opposite directions shown by arrows (P) in Fig. 14. It pushes it open.

[0038] By doing so, the band main body (11) will protrude outward from the one end (11a) of the bent end. The second convex channel wall (17) is raised upward, and the inwardly facing channel wall (11b) is also The concave channel wall (19), which is depressed in Finally, the fixing claw (20) protrudes from the center of the concave channel wall (19). , biting and locking to the second convex channel wall (17) as shown in FIG. As a result, the diameter (D) of the main body of the band (11) is contracted and deformed, and as a result, the hose (1 0) is firmly attached to the joint pipe, opening/closing valve, or other equipment's mouth part (25) in a tightened state. It is determined. After fixing it, pull out the opening/closing operation tool (B) to the outside. It goes without saying that.

[0039] Figures 16 and 17 show modified examples of the expansion operation tool corresponding to Figures 12 to 15 and their use. This shows the caliber contraction effect of the hose band due to A hose (1) in which one end (11a) and the other end (11b) are crossed 10), the tool receiving opening opens at one end (11a). (12) and the tool relief opening (15), the other end side ( 11b) will be in communication with each other, so the Connect the operating claw (30) of a hook spanner type expansion operation tool (C) such as 11b) to the tool relief opening (21) on the one end side (11a). 5), then raise the handle (31) as shown in Figures 16 to 17, Due to the so-called lever action of the working claw (30), the band main body (11) similar to the above is It is also possible to obtain a constricted caliber condition.

[0040] In any case, the band main body (11) is wound on one end side (11a) and the other end side (11a). 1b) in opposite directions, the backing tongue on one end side (11a) The piece (13) forms a bead of the fourth convex channel wall (24) at the other end (11b). The backing tongue (13) is received and engaged in the groove, and has a ridge at the base of the backing tongue (13). The first convex channel wall (14) has a tool relief opening on the other end side (11b). Since it also engages with the opening (21), the above-mentioned band The main body (11) is smoothly contracted and deformed while always maintaining the correct overlap state. It will be.

[0041] In addition, a second convex channel is provided on the other end (11b) of the band main body (11). The wall (17) is raised, and on the other hand, there is a concave shape on one end of the bend (11a). The channel wall (19) is depressed and the concave channel wall (19) Since the fixed claw (20) is continuously and integrally extended from the center of the 20) sinks into the long window (16) that opens on one end side (11a), while the other end side (11a) sinks into the long window (16). 11b) and is engaged with the second convex channel wall (17), Therefore, there is no risk of them shifting laterally, and in the unlikely event that they are exposed to external forces such as vibration or shock. Also, the locking state with the bite will not be accidentally released or loosened, and its fixing strength will be maintained. It has outstanding stability and durability.

[0042] Further, there is a turning mechanism in which the working claws (26) and (30) of the expansion operation tools (B) and (C) are locked. The third convex channel wall (23) on the other bent end side (11b) and the one bent end The first convex channel wall (14) on the side (11a) is a literal channel. Because it has a flannel shape, it resists the expansion operation force by the working claws (26) and (30). It has excellent strength and does not protrude bulkily at acute angles, so the entire hose band itself is It is also significantly beneficial for physical flattening and handling safety. In addition, the above fixed Intentionally releasing the locked state between the claw (20) and the second convex channel wall (17) Therefore, it goes without saying that the hose band can be removed from the hose (10). Nor.

[0043]

[Effect of the idea]

As mentioned above, in the present invention, the band is made of a metal strip (M) cut to a fixed size. The main body (11) is partially circumscribed by its one end side (11a) and the other end side (11b) It is rolled up into a different circular ring shape to make it three-dimensional, and its diameter (D) is artificially reduced. A hose band that fixes the hose (10) in a neck tightening state by contracting and deforming it. In this case, the tip of the one end (11a) of the winding is provided with a first bulge extending outward. a convex channel wall (14) and a tool receptacle thereby defining an opening edge; A channel wall (14) is provided with an opening (12), and the band body (11) The backing tongue piece (13), which is narrower than the above, is extended, and the one end side ( In the middle part of 11a), there is a tool escape port adjacent to the tool receiving port (12). (15) and a long window (16) that is more slender than this, a second protrusion that also protrudes outward. While the openings are distributed through the shaped channel wall (17), the other end side of the winding (1 1b) has a concave channel wall (19) that sinks into the long window (16). and a receiving opening (18) of the second convex channel wall (17) adjacent thereto. is provided, and the fixing claw (20) is inserted into the center of the concave channel wall (19). It protrudes continuously and integrally toward the entrance (18), and also bends at the other end ( In the middle of 11b), a third convex channel wall (23) that protrudes outward is inserted. The tool escape opening (21) adjacent to the receiving opening (18) also faces outward. The tool relief opening (21) is connected to the tool through the fourth convex channel wall (24) which is raised to and the adjacent long window (22) with aperture distribution, and the backing tongue piece (13) has a fourth convex shape. Relief into the bead groove of the shaped channel wall (24) and engage the backing state. As a result, the band main body (11) is rolled up so that one end side (11a) and the other end side (11a) are rolled up. 11b) is designed so that it can be rolled up into a circular ring shape to be circumscribed and made into a three-dimensional object. At the same time, the diameter (D) of the band main body (11) was artificially contracted and deformed. At the same time, the second convex channel wall (17) on the one end side (11a) of the winding A fixing claw (20) protrudes from the concave channel wall (19) at the other end (11b). Since the relationship is set so that they bite and lock each other, the conventional technology mentioned at the beginning It has the effect of improving all of the problems.

[0044] In other words, the hose band of the present invention differs from the prior invention mentioned at the beginning because of its structure. A second convex tip protrudes outward from one end (11a) of the main body (11) of the main body (11). The other end (11b) of the same folded wall (17) is bent inward. A fixed claw (20) protruding from the concave channel wall (19) is attached to one end side (11) of the fixed claw (20). a) It bites and locks when it sinks into the long window (16). As a result, the second convex channel wall (17) may inadvertently bend outward. Hose (10) is kept flat, stable, and strong without fear of being stranded. It is possible to maintain tightness.

[0045] Also, the first convex channel wall (14) on the one end side (11a) of the winding, and the other The third and fourth convex channel walls (23) and (24) on the end side (11b) are also literally Since it is in a state of crossing the band main body (11) as a channel type, the band Unlike the one that is sharply bent outward from the main body (11), it is extremely safe to handle. Not only that, but the hose band itself as a whole becomes noticeably flattened, and as a result, Even when the fruit hose (10), its joint pipe, or other equipment rotates, There is no risk of interfering with the rotational movement.

[0046] Moreover, the pair of left and right working claws (26) of the expansion operation tool (B) The first convex channel wall (14) on one bent end side (11a) and the other bent side (11a) 11b) to be locked to the third convex channel wall (23), It is also extremely strong against the expansion operation force by the action claw (26), and the operation force is There is also a risk that the receiving channel walls (14) and (23) will warp and lose. do not have.

[0047] Also, as for the expansion operation tool (B), the pair of left and right working claws (26) are the same. Using pliers with common shapes, you can freely and without restrictions band-based (11 ) can be added to the expansion operation, and furthermore, a very simple expansion operation like a hook spanner can be added. Even the production tool (C) can be used, and it does not require extensive experience or high skill. There is also the effect that the tightening work of the hose (10) can be carried out efficiently.
