  Next, an example of a conventional configuration for expanding and contracting the expansion joint pipe 4 will be described with reference to FIGS. 5 and 6 are longitudinal sectional views of the expansion joint pipe 4. In FIG. 5, a hand operating tube 3 is connected to one end of the outer tube 4a, and a lock lever (not shown, similar to a lock lever 21 provided on the inner tube 4 to be described later) is provided on the hand operating tube 3. A recess 13 is provided for engaging the claw 12 of the configuration. On the other end side of the outer cylinder 4a, that is, the side on which the inner cylinder 4b is slidably fitted in the longitudinal direction, an inner cylinder support member 14 that slidably supports the outer periphery of the inner cylinder 4b, a seal member 15, The outer periphery of the seal member 15 is in close contact with the inner periphery of the outer cylinder 4a, and the outer periphery is in close contact with the outer periphery of the inner cylinder 4b to ensure airtightness between the outer cylinder 4a and the inner cylinder 4b. An expansion / contraction locking means 16 is provided between the inner cylinder support member 14 and the seal member 15, and is supported so as to be movable in a direction orthogonal to the direction in which the inner cylinder 4b expands and contracts, that is, in the direction of the arrows 17a to 17b. The spring (elastic means, biasing means) 18 is biased in the direction of the arrow 17b toward the inner cylinder 4b. A slope 16 a is formed on a part of the telescopic locking means 16.

  The expansion / contraction operation unit 9 is supported in the vicinity of the expansion / contraction lock means 16 so as to be movable along the outer cylinder 4a, and a slope 9a is formed in a part thereof. The periphery of the telescopic operation unit 9 is covered with an outer cylinder cover 23. An inner cylinder support member 20 is provided at one end of the inner cylinder 4b on the hand operation tube 3 side, and supports the inner cylinder 4b so as to be slidable with the outer cylinder 4a. The mouthpiece 5 or the auxiliary brush part 7 is connected to the other end of the inner cylinder 4b. The lock lever 21 is swingably supported around the support shaft 21a, and a claw portion 21b provided at one end of the lock lever 21 by the urging force of a spring (elastic means, urging means) 58 is provided on the inner cylinder 4b. It is the structure which protrudes inside and can be fitted and fixed to the recessed part provided in the applicable part of the suction mouth 5 or the auxiliary brush part 7. FIG. When the convex portion 21c is pushed toward the inner cylinder 4b against the urging force of the spring 58, the lock lever 21 swings around the support shaft 21a and the claw portion 21b moves away from the inner cylinder 4b. Therefore, the engagement with the mouthpiece 5 or the auxiliary brush part 7 is released and the structure can be separated. The inner cylinder 4 b is provided with a plurality of recesses 22 in the expansion / contraction direction. When the expansion / contraction locking means 16 is moved in the direction of the arrow 17 b by the spring 18, a part of the expansion / contraction locking means 16 is one of the recesses 22. By engaging the two, the inner cylinder 4b and the outer cylinder 4a can be locked.

The slope 9a provided in the extension / contraction operation section 9 abuts on the slope 16a provided in the extension / contraction lock means 16, and the extension / contraction lock means 16 is moved in the direction of the arrow 17a against the urging force of the spring 18. The fitting between the means 16 and the recess 22 of the inner cylinder 4b is released, and the inner cylinder 4b can freely move in the longitudinal direction with respect to the outer cylinder 4a to expand and contract. Since a plurality of recesses 22 are provided at predetermined intervals in the axial direction, the inner cylinder 4b and the outer cylinder 4a are locked again when the telescopic lock means 16 is fitted to any one of the recesses 22.

  With the above-described configuration, the expansion joint pipe 4 that can be adjusted in length by the inner cylinder 4b and the outer cylinder 4a being supported in an extendable manner can be realized. Here, if the expansion / contraction operation part 9 and the expansion / contraction operation rod 24 extended in the longitudinal direction of the outer cylinder 4a are connected, and further configured to be operated by the fifth operation rod 31 described in FIG. The expansion joint pipe 4 can be expanded and contracted by operating the operating means 8 provided in the operating pipe 3. Therefore, both expansion and contraction of the expansion joint pipe 4 and separation of the suction body 5 can be performed by operating the operation means 8. It is preferable that the operation of the operation means 8 for expanding and contracting the expansion joint pipe 4 and the operation of the operation means 8 for separating the suction body 5 are different.

  Next, the structure of the rod connecting means 11 capable of connecting the first operating rod 10a provided on the outer cylinder 4a and the second operating rod 10b provided on the inner cylinder 4b to each other in the present invention. An example will be described with reference to FIGS. FIG. 9 is a longitudinal sectional view showing an example of the expansion joint pipe 4 provided with the rod connecting means 11, and FIG. 10 is a plan view of FIG. 9 viewed from the E direction. 11 to 13 are schematic configuration diagrams showing an example of the configuration and operation of the rod connecting means 11. The same components as those in FIGS. 5 to 6 are denoted by the same reference numerals and detailed description thereof is omitted.

  As described above, the first operating rod 10a is provided on the outer cylinder 4a, and is provided so as to be movable in the longitudinal direction (axial direction) of the outer cylinder 4a. The second operating rod 10b is provided on the inner cylinder 4b, and is provided so as to be movable in the longitudinal direction (axial direction) of the inner cylinder 4b. In the vicinity of the outer cylinder 4a on the side of the inner cylinder 4b in the axial direction, rod connecting means 11 for connecting the first operating rod 10a and the second operating rod 10b is provided. When the inner cylinder 4b is moved with respect to the outer cylinder 4a in order to expand or contract the length of the expansion joint pipe 4, the second operation rod 10b and the rod connecting means 11 are slid with respect to each other to perform the second operation. The position of the rod 10b does not move with respect to the inner cylinder 4b. On the other hand, since the first operating rod 10a and the second operating rod 10b are connected by the rod connecting means 11 when the first operating rod 10a is moved in the direction of the arrow 19, The rod 10b is also configured to move in the arrow 19 direction. Here, as will be described later, the moving amount B ′ of the second operating rod 10b is smaller than the moving amount B of the first operating rod 10a.

  FIG. 11 shows the rod connecting means 11 in a state where the operating means 8 provided on the hand operating tube 3 is not operated. In FIG. 11, the rod connecting means 11 is pressed against the case portion 11a provided on the outer cylinder 4a and one surface by the first operating rod 10a, and the other surface (the surface opposite to the one surface) is a spring (elastic means, biasing). (Means) 11c provided with a lock plate 11b urged by 11c and step portions (stopper means) 11d, 11e for supporting the lock plate 11b with respect to the case portion 11a. The case part 11a is fixed to the outside of the outer cylinder 4a. Holes 11f, 11g, and 11h that are larger than the second operating rod 10b penetrate through the axial front end surface and end surface of the case portion 11a and the lock plate 11b in the axial direction. The step portions 11d and 11e and the spring 11c restrict movement of at least the axial direction of the lock plate 11b. The width of the lock plate 11b is preferably slightly smaller than the width of the inner surface of the case portion 11a so that the lock plate 11b can be pivoted (tilted) in the axial direction within the case portion 11a. The thickness of the lock plate 11b in the axial direction is preferably thin so as to be rotatable (tiltable) in the axial direction in the case portion 11a. The axial positions of the stepped portions 11d and 11e are such that when the first operating rod 10a is not pushed, the lock plate 11b is substantially perpendicular to the axial direction and the through-hole direction of the hole 11h is substantially parallel to the axial direction. Are preferably substantially equal (here, the word "abbreviation" means that an error is included in addition to a perfect match, and so on). And the substantially center of the width direction of one surface of the lock plate 11b is supported by the end of the first operating rod 10a (may be connected). The end of the second operating rod 10b supports (connects) a position shifted from the approximate center in the width direction of the other surface of the lock plate 11b. Further, the end of the spring 11c supports a position shifted from the approximate center in the width direction of the other surface of the lock plate 11b to the opposite side in the width direction from the support portion by the end of the second rod 10b. Also good). The spring 11c extends in the axial direction, that is, the moving direction of the first operating rod 10a and the moving direction of the second operating rod 10b, and the other end of the spring 11c is supported inside the case portion 11a. In the state shown in FIG. 11, the second operating rod 10b is slidable in the longitudinal direction when the holes 11f, 11g, and 11h face in a direction substantially parallel to the longitudinal direction. A hole 11i larger than the first operating rod 10a is opened in the case portion 11a, and the first operating rod 10a is slidable in the longitudinal direction with respect to the case portion 11a. Further, the first operating rod 10a and the spring 11c are not opposed to each other and are shifted in position by a distance C. As a result, the point of action of the pressing force of the first operating rod 10a and the point of action of the pressing force (restoring force) of the spring 11c are shifted, so that the lock plate 11b is rotatably supported by the case portion 11a by the support shaft. Even if not, it is possible to turn back and forth in the axial direction around the support portion by the first operating rod 10a (more precisely, in the middle of the thickness direction of the lock plate 11b corresponding to the support portion). . The support portion of the lock plate 11b by the end portion of the spring 11c may be shifted from the substantially center in the width direction of the other surface of the lock plate 11b to the same side in the width direction as the support portion by the end portion of the second rod 10b. Good. Further, the support portion of the lock plate 11b by the end portion of the spring 11c may be formed on the same surface as the one surface on which the support portion by the first operating rod 10a of the lock plate 11b is formed.

  That is, when the operation means 8 is not operated as shown in FIG. 11, the expansion / contraction operation section 9 is operated to move the expansion / contraction lock means 16 in the direction of the arrow 17a to release the fitting of the inner cylinder 4b into the recess 22 When the inner cylinder 4b moves in the longitudinal direction relative to the outer cylinder 4a and expands and contracts, the second operating rod 10b moves with the inner cylinder 4b, but the second operating rod 10b is the case of the rod connecting means 11. Since both the portion 11a and the lock plate 11b are slidable, they can freely expand and contract without hindering expansion and contraction of the inner cylinder 11b and the outer cylinder 11a, and the position of the second operating rod 10b does not move relative to the inner cylinder 4b.

  Next, the operation when the operating means 8 is operated will be described with reference to FIGS. In FIG. 12, when the operating means 8 is operated, the first operating rod 10a moves in the direction of the arrow 26a (the pressing direction), and the tip of the first operating rod 10a presses the lock plate 11b. Here, since the positions of the first operating rod 10a and the spring 11c are shifted by the distance C, the support portion between the first operating rod 10a and the lock plate 11b moves toward the distal end side in the axial direction. The lock plate 11b rotates in the direction of the arrow 26b (the axial front end side) with the support portion between the operation rod 10a and the lock plate 11b as a fulcrum, but the inner periphery of the hole 11h provided in the lock plate 11b and the second operation rod 10b contacts at two points of the contact point 11j and the contact point 11k in a diagonal position relationship, and the lock plate 11b and the second operation rod 10b are engaged with each other by a frictional force. As shown in FIG. 13, when the first operating rod 10a is further moved in the direction of the arrow 26a, the lock plate 11b and the second operating rod 10b are moved in the direction of the arrow 26c while being engaged with the contact 11j and the contact 11k. . That is, since the second operating rod 10b moves when the first operating rod 10a is operated, the second operating rod 10b provided on the inner cylinder 4b is operated when the operating means 8 is operated. That is, the first operating rod 10a and the second operating rod 10b are first operated by pulling the operating means 8 to operate the first operating rod 10a by one (single) operation of the operating means 8. Are connected by the rod connecting means 11, and then the first operating rod 10a and the second operating rod 10b are operated by continuing one operation of the operating means 8 by further pulling the operating means 8 or the like, The lock (connection) of the mouthpiece 5 is released. On the other hand, when one operation of the operation means 8 is not performed, the connection between the first operation rod 10a and the second operation rod 10b is released.

  Here, as shown in FIG. 13, if the moving amount of the first operating rod 10a is B and the moving amount of the second operating rod 10b is B ', the first operation rod shown in FIGS. Even if the operating rod 10a is operated, only the second operating rod 10b and the lock plate 11b are engaged with each other, and the second operating rod 10b does not move, so that the relationship of B> B ′ is established.

  As described above, since the lock plate 11b and the second operating rod 10b are configured to engage with each other by frictional force, the surface of the second operating rod 10b is provided with irregularities or roughened, and the lock The frictional force with the plate 11b may be increased to further ensure engagement.

  Next, an example of a configuration in which the operating unit 8 is provided with the operating unit 8 will be described with reference to FIG. FIG. 14 is a partial perspective view of the hand control tube 3. Cleaning is performed while gripping the grip portion 27 in the hand operation pipe 3 and moving the suction body 5 placed on the floor surface via the expansion joint pipe 4 back and forth. The lock means 51 is provided on the expansion joint pipe 4 side of the hand operation pipe 3, but since this has the same structure and operation as the lock means 21 described above, detailed description thereof will be omitted. The grip portion 27 is provided with an operating means 8, is supported so as to be slidable in the direction of the arrow 28 a, and a fulcrum 8 a is provided integrally with the operating means 8.

  The conversion link 30 is rotatably provided around a rotation fulcrum 30a, a fulcrum 30b is provided at one end, and a fourth operation rod is provided between the fulcrum 8a of the operation means 8 and the fulcrum 30b of the conversion link 30. 29 is provided. The conversion link 30 is provided with a fulcrum 30c at the other end of the rotation fulcrum 30a, and a fifth operation rod 31 is provided between the end face 3a connected to the expansion joint pipe 4 of the hand operation pipe 3. ing. When the operating means 8 is moved in the direction of the arrow 28a, the fourth operating rod 29 supported by the fulcrum 8a provided integrally with the operating means 8 is also operated in the direction of the arrow 28a, and the conversion ring 30 rotates to turn the fulcrum 30c. Is moved in the direction of the arrow 28b, and the fifth operating rod 31 is moved in the direction of the arrow 28b so as to protrude from the end face 3a. That is, the conversion link 30 converts the pulling operation of the fourth operating rod 29 into the pressing operation of the fifth operating rod 29.

  Here, if the end face of the fifth operating rod 31 and the end face of the first operating rod 10a provided on the outer cylinder 4a of the expansion joint pipe 4 are arranged or connected to face each other, the operating means 8 is operated. Thus, the fifth operating rod 31 can be operated, and the first operating rod 10a can be further operated.

  Further, as described above, the first operating rod 10a and the second operating rod 10b are connected by the rod connecting means 11, and as a result, by operating the operating means 8, the second operating rod 10b is moved. It can be operated.

  Next, an example of a detailed configuration of the auxiliary brush portion 7 in the present invention will be described with reference to FIGS. 15 to 16. 15 and 16 are perspective perspective views showing the configuration of the auxiliary brush portion 7. An auxiliary brush holder 33 is slidably provided in the longitudinal direction inside a substantially cylindrical auxiliary brush case 32 having one end coupled to the inner cylinder 4b of the expansion joint pipe 4, and a spring (a biasing member) The auxiliary brush case 32 is urged in the direction of the arrow 34a by the elastic means and urging means 34). An auxiliary brush bracket 35 a in which an auxiliary brush 35 b is planted is provided at the other end of the auxiliary brush holder 33, and the auxiliary brush holder 33 is rotatable by a rotation surface 36 inclined with respect to the longitudinal direction between the auxiliary brush holder 33. It is supported by. This rotation operation will be described later.

  The auxiliary brush case 32 is provided with suction mouth separating means 70. The suction port separating means 70 is provided with a lock mechanism 7a, and is supported so as to be swingable around a fulcrum 7c. The lock mechanism 7a is provided with an operation portion 7d, and a projection 7f is provided adjacent to the operation portion 7d. On the other end side with respect to the fulcrum 7c, a claw 7e is provided so as to protrude toward the inside of the auxiliary brush case 32. On the side of the third operating rod 7b close to the lock mechanism 7a, the unlocking means 37 is provided in conjunction with the third operating rod 7b, and a part thereof is an inclined surface 37a. It is provided in the vicinity of the provided projection 7f.

  FIG. 15 illustrates a state in which the third operating rod 7b is not operated. The inclined surface 37a is not in contact with the protrusion 7f, and the claw 7e protrudes toward the inside of the auxiliary brush case 32. When the mouthpiece 5 is inserted from the tip of the auxiliary brush portion 7, that is, from the auxiliary brush 35b side, the mouthpiece 5 pushes the auxiliary brush bracket 33 against the biasing force of the spring 34, and the tab 7e further sucks the mouthpiece. The body 5 can be locked and fixed.

  FIG. 16 shows a state in which the third operating rod 7b is operated and moved in the direction of the arrow 38a. Since the inclined surface 37a is in contact with the protrusion 7f, the protrusion 7f moves along the inclined surface 37a, and the lock mechanism 7a is moved. Swings around the fulcrum 7c in the direction of arrow 38b. Since the locking mechanism 7a swings, the claw 7e also moves in the direction of the arrow 38, so that the lock with the mouthpiece 5 is released. In this manner, the suction port can be removed by the suction port separating means 70.

  Next, using FIG. 17 to FIG. 18, the auxiliary brush portion 7 provided at the tip of the inner cylinder 4 b of the expansion joint pipe 4 and the suction body 5 provided at the tip of the auxiliary brush portion 7 are separated. The operation of the inlet separation means 70 will be described. 17 and 18 are cross-sectional views showing the configurations of the expansion joint pipe 3, the auxiliary brush portion 7, the suction body 5, and the suction separation means 70. FIG. 17 shows a state in which the inner cylinder 4 b of the expansion joint pipe 4, the auxiliary brush portion 7, and the suction body 5 are connected, and a claw 7 e is a recess provided in the suction body 5 attached to the auxiliary brush portion 7. It meshes with 5b. At this time, the auxiliary brush holder 33 is pushed by the suction body 5 and resists the urging force of the spring 34 contained in the auxiliary brush portion 7. Here, the operating portion 7d is operated, or the third operating rod 7b is operated, and the suction port separating means 70 is operated as shown in FIGS. 16 to 18, and the lock mechanism 7a swings. When the claw 7e is released by the above, the urging force of the spring 34 causes the auxiliary brush holder 33 to extend in the direction of approaching the suction body 5, thereby giving a force for opening the suction body 5 and the auxiliary brush portion 7. The mouthpiece 5 is advantageous because it is more easily separated from the auxiliary brush portion 7.

  19 and 20 show an example of a configuration in which the auxiliary brush 35 is rotated in the direction of the arrow 56 along the rotation surface 36 in the auxiliary brush unit 7 to change the direction of the auxiliary brush 35b. Since it is inclined with respect to the longitudinal direction, the angle with the longitudinal direction is inclined by rotating, so it is easy to clean vertical surfaces such as windows and shelves of various heights. is there. On the other hand, as shown in FIG. 15 to FIG. 16, in the state where the auxiliary brush 35b is oriented in the longitudinal direction, the separation / attachment operation with the mouthpiece 5 is performed.

  With the above configuration, when the operating means 8 provided on the hand operating tube 3 is operated, the first operating rod 10a provided on the outer cylinder 4a of the expansion joint pipe 4 is mechanically operated, and the rod connecting means 11 is moved. Since the second operating rod 10b is mechanically operated and the third operating rod 7b is mechanically operated, the lock mechanism 7a provided in the auxiliary brush portion 7 is mechanically operated. The suction mouth separating means 70 is mechanically operated to separate the auxiliary brush portion 7 and the mouthpiece body 5, and the mouthpiece body can be separated by the operation at hand. That is, with one operation of the operation means 8, the connection between the first operation rod 10a and the second operation rod 10b and the separation between the auxiliary brush portion 7 and the mouthpiece 5 are realized. On the other hand, when the operating means 8 is not operated, the first operating rod 10a and the second operating rod 11b are in a state where the connection between the first operating rod 10a and the second operating rod 11b is released. Since they can slide in the axial direction, that is, in the axial direction while changing the overlap amount, the expansion joint pipe 4 can be assisted by the same operation of the operating means 8 in the extended state or in the shortened state. The brush part 7 and the mouthpiece 5 are separated. Thereby, an easy-to-use vacuum cleaner can be provided.

  In the above-described embodiment, the suction body 5 is separated from the auxiliary brush portion 7. However, the suction body 5 is not limited to the suction body 5. For example, a narrow slit shape suitable for cleaning a narrow portion is used. It may be a mouthpiece and other cleaning accessories.

  In addition, the present invention is not limited to the separation of the suction body from the expansion joint pipe of the vacuum cleaner, and in a stretchable structure, the operation from one end of the structure is mechanically transferred to the other end of the structure ( Applicable to anything that is transmitted (not electrical).

  Next, another embodiment will be described with reference to FIGS.

  Another embodiment of the rod connecting means of the first operating rod 10a and the second operating rod 10b will be described with reference to FIGS. FIGS. 21 and 22 are longitudinal sectional views showing an example of the expansion joint pipe 4 provided with another embodiment of the rod connecting means 40 different from FIGS. 9 and 10, respectively. FIG. FIG. In this embodiment, a part of the first connecting rod 10a forms a cylindrical pipe 10c, and the second connecting rod 10b is inserted inside the cylindrical pipe 10c.

  The detailed structure of the rod connecting means 40 will be described with reference to FIGS. 23 to 25, and the operation thereof will be described with reference to FIGS. 23 to 25 are perspective views of the rod connecting means 40, and FIGS. 26 to 28 are schematic sectional views showing the operation.

  The clamp member 41 shown in FIG. 23 has a hole 41a larger than the second connecting rod 10b, and one end 41d of the outer periphery 41b has a smaller diameter than the other end 41e and has a tapered shape. The end portion on the end 41e side has a flange shape 41f having a large outer diameter. The clamp member 41 is provided with a plurality of radial slits 41c except for the vicinity of the one end 41d until reaching the other end 41e, and the gaps of the slits 41c are mutually spaced from the other end 41e toward the inner periphery. When it is compressed until it comes into contact, the hole 41a is also compressed on the other end side so that the hole diameter becomes smaller than the diameter of the second connecting rod 10b.

  In FIGS. 24 and 25, the second connecting rod 10b is passed through the hole 41a of the clamp member 41, and the tapered outer periphery is one end on the inner periphery of the cylindrical pipe 10c which is a part of the first connecting rod 10a. It is inserted from the side of 41d. Here, if the outer circumference of one end 41d of the cylindrical pipe 10c of the clamp member 41 is the diameter D1, and the outer circumference of the other end 41e is the diameter D2, the inner circumference D3 of the cylindrical pipe 10c is intermediate between D1 and D2, and D1 <D3 < The relationship is D2. Still further, when the cylindrical pipe 10c is inserted along the tapered outer periphery 41b of the clamp member 41 so as to be close to the other end 41e, one end of the cylindrical pipe 10c comes into contact with the other end 41e of the clamp member 41. The gap between the slits 41c has been in contact with each other before, and the cylindrical pipe 10c cannot approach the other end 41e side of the clamp member 41 beyond that.

  That is, as shown in FIG. 24, when the clamp member 41 is only partially inserted into the cylindrical pipe 10c and the distance is F1, the slit 41c has a gap and the hole 41a has the second connecting rod 10b. The second connecting rod 10 b can slide relative to the clamp 41. On the other hand, as shown in FIG. 25, when the cylindrical pipe 10c is brought close to F2 on the other end 41e side of the clamp member 41, D3 <D2, and the slit 41c is compressed on the other end 41e side of the clamp member 41. The diameter of the hole 41a of the clamp member 41 becomes smaller and smaller than the diameter of the second operating rod, and thus the hole 41a and the second connecting rod 10b are configured to engage with each other by frictional force.

  26 to 28 are schematic diagrams for explaining the operation of the rod connecting means 40 described above. 26 and 27 show a state in which the first connecting rod 10a is not operated. FIG. 26 shows the most extended position, and FIG. 27 shows the most contracted position. The first connecting rod 10a and the clamp member 41 are biased in the direction of the proximal operation tube 3 on the right side of the drawing by springs 42a and 42b, respectively. In this case, since the inner diameter of the hole 41a of the clamp member 41 is larger than the diameter of the second connecting rod 10b, the clamp member 41 and the second connecting rod 10b are slidable. The cylinder 4a and the inner cylinder 4b can freely expand and contract. Here, even when the expansion joint pipe 4 is most extended as shown in FIG. 26, the second connecting rod 10b is not detached from the clamp member 41, and the expansion joint pipe 4 is most contracted as shown in FIG. Also, it is convenient to arrange the dimensional relationships so that the second connecting rod 10b is housed in the inner periphery of the cylindrical pipe 10c which is a part of the first connecting rod 10a.

  On the other hand, FIG. 28 illustrates a state in which the first connecting rod 10a is operated. When the first connecting rod 10a is operated, the cylindrical pipe 10c is also moved to the left in the drawing against the biasing force of the spring 42a. 25, after the clamp member 41 and the second connecting rod 10b are engaged with each other as described above with reference to FIG. 25, the second connecting rod 10b is operated together with the first connecting rod 10a to be B '( Here, B> B ′) is moved, and as shown in FIG. 16, the third operating rod 7b provided on the auxiliary brush portion 7 provided on the left side of the drawing is further moved to operate the inlet separating means 70. Thus, the mouthpiece 5 can be separated.

  As described above, the clamp member 41 and the second operating rod 10b are configured to engage with each other by frictional force, so that the surface of the second operating rod 10b is provided with irregularities or roughened so that the clamp The frictional force with the member 41 may be increased to further ensure engagement.
