A release guide protrusion 15 including an incision 15a which is formed at an lower end of the locking protrusion 13 in an oblique form (also in the drawing, from the left side to the right side), and

It has a second guide groove 14 formed in the vertical direction to match the uppermost portion of the cutting projection 13, the cutout portion 13a,

The first guide groove 11, the locking protrusion 13, the second guide groove 14, the release guide protrusion 15 set S has a guide portion G formed in plural.

The depth of the second guide groove 14 is shallower than the depth of the first guide groove 11 so that the pivoting teeth 35 of the pivoting protrusion 33 of the rotating body 30 is the second guide groove 14. It should be possible to catch the incision 15a at the bottom.

In the drawing, the set S has three sets.

If the set is two sets, the width of each of the first guide groove, the engaging projection, the second guide groove, and the release guide projection should be wider than that shown.

In the case of four sets, the width of each of the first guide groove, the engaging projection, the second guide groove, and the release guide projection should be narrower than that shown.

In any case, considering the rotation of the rotating body 30, the first projection groove 11, the second guide groove 14, the engaging projection 13 except for the portion overlapping with the second guide groove, and release Each of the guide protrusions 15 should be the same width,

Since the first guide groove 11 and the second guide groove 14 should be sized to accommodate the rotational projection 33 of the rotating body 30 and the idle prevention projection 41 of the sub-receptor 40. As the width of each guide groove varies, the width of each protrusion 33 and 41 should also vary.

In addition, the position limiting jaw 19 formed at the upper end of the first guide groove 11 and the second guide groove 14 absorbs the function of the locking jaw 17 so that the spring ( 60) may serve as a support, and the locking step is omitted.

Next, in the main receptor 20, the brush 1 as an object is coupled to the front end,

Departure preventing jaw 21 for limiting the downward movement of the rotating body 30 is formed,

It is embedded in the housing 10,

As the coupling method of the brush 1, various methods such as interference fitting, screwing, and bonding by an adhesive may be selected.

In the forward and backward movement of the press body 50 forming the moving means (M) [combination of the sub-receptor 40-main receptor 20-the object 1] in conjunction with the forward and backward,

As described below, the rotating body is rotated while the rotating protrusion 33 of the rotating body 30 and the shifting teeth 35a of the sub-receptor 40 idle stop 41 are engaged with each other. The object 1 is drawn out to the outside of the access hole 12A of the housing 10 to be exposed or embedded in the housing 10, depending on whether the locking protrusion 13 of the housing 10 is caught. It's done,

In the illustrated form, the rotating body 30 is idling form along the outer circumferential surface of the fitting portion 23 at the rear end of the release prevention jaw 21 of the main receptor 20,

In some cases, unlike the form shown in the figure [compression body 50-sub-receptor 40-main body 20-the combination of the object (1)] in the form of interlocking together in accordance with the rotation of the rotating body 30 If implemented [the second rack 81 of the opening and closing means 80-the pinion (P)-the first rack 25 of the main receptor 20] should always be engaged, the [pressure member 50-sub-acceptor [40] -Main receptor 20-Combination of the object 1] [second rack 81 of the opening and closing means 80-pinion (P)-first rack of the main receptor 20 (25) )] Must not be affected.

To this end, in the drawing, the main receptor 20 is composed of two powders 20A and 20B, and the coupling form of the two powders is one of the male and female coupling parts 20b and 20a, which is capable of idling and preventing separation. It is provided at the end to be mutually coupled.

However, in the drawing, since the rotating body 30 is idling, the main receptor 30 does not need to be made of two powders, and even if the main receptor is made of two powders, the idling structure is not essential.

However, considering that the first rack 25 is formed in the front powder 20A of the main receptor 20, the front and rear powder 20A, 20B as shown in the main receptor for convenience of manufacturing It will be convenient to make it separately.

Subsequently, the rotating body 30 has a hollow 31 that can be fitted to the fitting portion 23 behind the main receiving body 20, in particular, the separation prevention jaw 21 of the rear powder 20B,

A plurality of pivoting protrusions 33 having a number and width corresponding to the number and width of the first guide grooves 11 of the guide part G of the housing 10 are formed on an outer circumferential surface thereof.

At the rear end of the pivoting projection 33, the oblique direction of the locking projection 13 and the release guide projection 15 of the guide portion G of the housing 10, that is, the forming direction of each cutout portion 13a and 15a, and Rotating teeth 35 are formed by forming an incision 35a having an opposite diagonal shape (in the figure, a diagonally descending right to left shape and having a high left side and a low right side).

As shown in FIG. 2B, the direction in which the cutout portions 13a and 15a of the locking protrusion 13 and the release guide protrusion 15 and the cutout portion 35a of the pivoting teeth 35 are formed, It will be described based on the direction formed when the guide portion (G) is directly viewed from the inside of the housing.

The rotation protrusion 33 of the rotating body 30 is 'corresponding' to the number of the first guide grooves 11 is formed as shown in the three first guide grooves, the rotation projections Three are also formed, which means that they are formed in the same number.

In addition, the width of the rotation protrusion 33 of the rotating body 30 has a dimension corresponding to the width of the first guide groove 11, the rotation projection is coupled to the first guide groove without difficulty. It means having a relative width that can be slid.

The sub-receptor 40 is interlocked with the rotational teeth 35 of the rotational projection 33 of the rotational body 30 to form the cutout portion 35a of the rotational teeth 35. A shifting tooth 41a having a number corresponding to the number of the pivoting projections 33 is formed at the front end to rotate in the opposite direction to the first direction, and the first guide groove 11 and the second guide of the housing 10. The idle prevention protrusion 41 which advances along the groove 14 is formed in the outer peripheral surface,

When looking at the forward and backward hole 12B of the housing 10 in front, the rotating body 30 rotates in a clockwise direction in the case V of the illustrated form.

In addition, in the multi-purpose case (V) according to the present invention, the distance between the separation prevention jaw 21 of the main receptor 20 and the front end of the displacement teeth 41a of the idle prevention projection 41 is the main body of the rotor 30. The distance to rotate the fitting portion 23 of the receiver 20 to the axis should be ensured.

The idle prevention projection 41 of the sub-acceptor 40 should not always leave the first guide groove 11 and the second guide groove 14 of the housing 10, the sub-receptor 40 itself does not rotate I'm just going out

When the sub-receptor 40 moves forward, the idle stop 41 moves forward along the first guide groove 11 and the second guide groove 14 and the shift teeth 41a

When located in the first guide groove 11 (when the brush is located inside the housing: first position) or

When the top of the cutout portion 13a of the locking projection 13 is located (when the brush 1 is exposed outside the entrance hole 12A of the housing: second position)

The rotary protrusion 33 of the rotating body 30 is in contact with the rotating teeth 35 and the highest point, and then rotates the rotating body while interlocking with the rotating teeth 35 so that the rotating protrusion 33 is

Move the brush from the first position to the second position so that the brush 1 is drawn out and exposed

The brush is moved from the second position to the first position so that the brush is accommodated in the housing.

To this end, the displacement teeth 41a of the idle prevention protrusion 41 form a peak at a portion coinciding with the center of the idle prevention protrusion, and form a diagonal line that is symmetrical to both sides at the peak.

In the figure, the right side of the shifting teeth 41a and the cutout portion 35a of the rotational teeth 35 abut the rotary body 30 in a clockwise direction.

As a result, the idle prevention protrusion 41 of the sub-acceptor 40 forms the crown gear 43 when viewed from the side of the shifting teeth 41a,

In addition, the idle prevention projections are formed twice, that is, six times the first and second guide grooves 11 and 14 of the housing 10 and the number of the rotation protrusions 33 of the rotating body 30.

Furthermore, since the shifting teeth 41a are symmetrical shapes, the cutouts 13a and 15a of the locking projections 13, the release guide projections 15 of the housing, and the rotational teeth 35 of the rotational projections 33 are also shown. Even if the formation direction of 35a is reversed from the figure, it can be used as it is.

The press body 50 is formed with a female screw 57 coupled to the rear end male thread portion 47 of the sub-receptor 40 and has a first rounded jaw exposed outside the recess 12B of the housing 10. Has 53.

In addition, the pressing member has an inserting portion 51 entering and exiting the inside of the housing 10 in response to the pressing of the pressing body 50, and the receiving portion of the sub-receptor 40 at the front end of the inserting portion 51. By contacting the rear end of the coil spring 60 through the second rounded projection 55 formed at a diameter difference from 45.

The coil spring 60 located on the outer circumferential surface of the receiving part 45 of the sub-receptor 40 is supported by the locking step 17 of the housing 10 at the front end,

An elastic force is exerted so that the [combination consisting of the main receptor 20-the rotating body 30-the sub-receptor 40-the pressing member 50] is pushed backward.

The shape of the pressing body may be variously modified, and if it is multifaceted, it should have a length of the insert 51 to ensure the displacement according to the exposure and storage of the object.

As described above, in the housing 10 consisting of two powders (10A) (10B) that are screwed through the respective male and female threaded portions (10a) (10b) in front of the guide portion (G).

Insert the [combination of main receptor 20-rotating body 30-sub-receptor 40] from the front to the rear of the second powder (10B),

Insert the coil spring 60 into the receiving portion 45 of the sub-receptor 40,

Subsequently, the press body 50 is combined,

Coupling the fitting ring jaw 75 of the fixed body 70 to the fitting ring groove 18 of the rear powder (10B),

The guide projections 85 of the opening and closing means 80, the opening and closing pieces 80A and 80B are coupled to each of the two slide grooves 73 of the fixing body 70,

Finally, when the front powder 10A is coupled to the rear powder 10B, it becomes the state of FIG. 3A and FIG. 2A.

In the drawing, the rear powder 20B and the sub-receptor 40 of the main receptor 20 are interference fit coupling, and the sub-receptor 40 and the press body 50 are screw-coupled,

If necessary, it can be variously modified such as screwing, interference fitting, adhesive bonding,

This also applies to the coupling method of the two powders 10A and 10B of the housing 10.

However, considering the convenience of maintenance, screwed coupling or interference fit would be preferable.

The width of the first and second guide grooves 11 and 14 ensures that the pivoting projection 33 of the rotating body 30 and the idling preventing projection 41 of the sub-receptor 40 slide smoothly. To the extent possible, it is desirable to ensure the reliability of brush retreat so that there is no play in the circumferential direction of the housing in the mutually coupled state such that the width of each of the protrusions 33 and 41 is possible.

The lengths of the first and second guide grooves 11 and 14 in the guide part G of the housing 10 should be drawn out, exposed, and stored again into the type of object, more specifically, the access hole 12A. Variable depending on the length of the subject

However, the length of the guide grooves 11 and 14 should be longer than the length of the idle stop projection 41 of the sub-acceptor 40.

In addition, the longer the guide grooves 11 and 14 and the shorter the height of the straight line of the locking protrusion 13, the longer the withdrawal and storage length of the object will be.

At this time, the outer circumferential surface 21 of the main receptor 20 should not collide with the locking protrusion 13 or the release guide protrusion 15.

In addition, the displacement of the object is the difference between the length of the uncompressed state and the maximum compression state of the coil spring (60)

The length of the insertion portion 51 of the pressing body 50 is limited.

In the present invention, the [combination body consisting of a main body-rotator-sub-receptor-pressor] is advanced, and the rotational projection 33 of the rotational body 30 is caught by the rotational projection 35 so that the locking projection 13 Even when the brush 1 is exposed,

When the second round jaw 55 of the press body 50 is supported by the spring 60 so as not to press the press body 50 forward, the assembly is always in the same manner as before pressing the press body. Since the rear end of the idle prevention projection 41 of the receiver 40 is caught in the position limiting jaw (19),

There is no concern that the pressing body, which is a problem pointed out in Utility Model Registration No. 0319261 in relation to the prior art, cannot be fixed and is retracted without resistance and can be regarded as a low quality case.

Nevertheless, in the present invention, the distance between the front end of the separation prevention jaw 21 of the main receptor 20 at the rear end of the shift teeth 41a of the idle prevention protrusion 41 of the sub-receptor 40 is the lower end of the rotor 30. At the same as the height up to the top of the rotational teeth 35 of the rotatable protrusion 33 or slightly larger enough to ensure a slight gap (for example, 0.001mm ~ 3mm),

The [combination consisting of the main receptor-rotator-subceptor-pressor] is moved back and forth together by the displacement according to the exposure and storage of the brush 1, which is the object, so that there is no loose feeling so that it feels like a higher quality case. You can have this
