Abstract

A pin-retained clip having a pin holder and a pin with a peripheral groove near its forward end. The pin holder is formed by bending a single oblong bendable sheet-like spring material at the center in its longitudinal direction. When bent, the material has, in a side view, a triangular shape having the top and a pair of inclined sections on both sides of the top. At the top is formed a pin retaining hole for inserting the pin. Also, a pair of holding members is projected from peripheral edge sections in the longitudinal direction of the pin retaining hole. The pair of holding members is projected in the same direction as the inclined sections and has a length that engages into the peripheral groove of the pin inserted in the pin retaining hole. In the clip, inserting the pin requires small force but drawing out the pin requires large force, and the clip can be released from a retained state by simple operation.

Description

The fixator of pin clamper type

Invention field

The present invention relates to the fixator of pin clamper type, comprise pin and pin clamper.The present invention is preferably applied to ornament especially, the fixator of tie clip, pin, earrings or necklace for example, but it also can be applicable to the fixator of the article of various relative reduced sizes except ornament.

Description of Related Art

Up to now, the fixator of pin clamper type is common in the health ornament, for example in the earrings, it is a kind of structure as having as shown in Fig. 1 (a), near the pin 1 that promptly fore-end, has peripheral groove 2, it is inserted in the pin fixator and (has omitted among the figure), and the hold assembly 3 of pin fixator is moved to lock it in the peripheral groove 2, and the position that is fixed.Like this, as shown in Fig. 1 (b), impel hold assembly 3 to leave peripheral groove 2, thereby can from the pin fixator, extract pin 1 by appropriate operation.

Specifically, in the fixator of in recent years pin clamper type, have many structures, in these structures, it all is to utilize the spring material with strain function to carry out that the peripheral groove neutralization that hold assembly moves to pin is therefrom withdrawn from.Because common pin fixator has little size, thus the structure that is simplified to fix device by the pin clamping device that utilizes spring material be just close actual.

As first correlation technique, can show the fixator of the ear accessories (earrings) that is proposed in the document of hereinafter mentioning 1.As shown in Fig. 2 (a), this fixator provides hole 6 in targeting part 5, and targeting part 5 is cores of substrate 4.Tubulose guide 7 can be assembled in the hole 6 like this, and insert pin by the through hole 8 of guide 7.Simultaneously, the peripheral part at substrate 4 has formed the flexible tab 9 that has guide groove 10.Flexible tab 9 slight bending constitute annulus 11 to the rear portion of substrate 4.That is to say, as shown in Fig. 2 (b), formed a kind of like this structure, promptly insert pin 12, impel annulus 11 to nip in its peripheral groove 13 from a side of the targeting part 5 of substrate 4, and clamping pin 12.

Next, as second correlation technique, Fig. 3 (a) and the shown pin fixator of sectional view (b) have been proposed also.In pin fixator 14, a pair of hold assembly of being made by material that can strain 16 is included in the inside of lid 15, and it is circular or oval-shaped on the whole.Be configured to roughly be centered at symmetrically the hold assembly 16 on the centrepin insertion portion 17, it respectively comprises the pin gripper arm 18 and the clamping limb 19 of shape shown in the figure.

Under the pinning state, as shown in Fig. 3 (a), each clamping limb 19 of these two hold assemblies 16 promotes other hold assembly 16 in the opposite direction, and the result promotes this to pin gripper arm 18 on the direction of pin insertion portion 17.For this reason, be arranged in the pin (figure has omitted) of pin insertion portion 17, it is clamped by pair of pin gripper arm 18.

Extracting from pin fixator 14 under the situation of pin, be projected into the button part 20 of lid 15 outsides from hold assembly 16, it is pressed against on the center position.By doing like this, as shown in Fig. 3 (b), this of biasing force that bears clamping limb 19 is to pin gripper arm 18, and it respectively leaves pin, and stops the pinning state.

Yet, in described first and second correlation techniques so far, mechanism makes the hold assembly (i.e. annulus 11 in first correlation technique and the pin gripper arm 18 in second correlation technique) of pin fixator come in contact from the peripheral groove of radial direction (right angle orientation) with pin.Under the situation of this class of establishment, pin insertion force (will sell needed power when inserting in the pin fixator) and pin withdrawal force (under the condition of not withdrawing from hold assembly, being used to extract the needed power of pin) have essentially identical intensity.Therefore, regulate hour, sell withdrawal force and also become less when will sell insertion force in view of the simplification of pinning operation.Thus, owing to when for example earrings is lived by hair volume, extract operation even without carrying out pin, the also danger that exists pin to deviate from.For this reason, earrings falls and does not notice, and to have lost earrings be not rarely seen.

Secondly, in described first correlation technique so far, need to make minimum tubulose guide 7, and it is assembled in the hole 6 of substrate 4.In addition, need mating part be fixed by for example welding.In addition, in described second correlation technique so far, need accurately make and minimum a pair ofly have complicated shape, and be installed in the pin fixator 14 in the lid 15.Therefore, the increase of its manufacturing expense and mounting cost is inevitable.

Example

Next, will provide the details description of example of the present invention based on accompanying drawing.Technical scope of the present invention is not limited to following example.

[example 1]

(process for making of example 1 and structure)

As shown in Figure 4, fixator 21 comprises pin clamper 22 and pin 23.

Fig. 4 (c) has shown the form element 24 that is used to make pin clamper 22.Can form form element 24 by lamellar spring material execution punching technology process or other suitable technical process to rectangle, for this lamellar spring material, the bending process process is feasible, and it has the elastic deformability.The core 25 of form element 24 (by the part of dotted line) is the part that forms the pin clamping hole.In core 25, by the recess 26 that certain shape is provided, a pair of hold assembly 27 that extends along the longitudinal direction of form element 24 has formed the shape that width wherein diminishes gradually towards front end.Have very important significance for the design tool though form the hold assembly 27 of this shape, this will be described in the example 2 later.

Between this front end, cut out the little space 28 of accurate Calculation and design to hold assembly 27.In other words, be a kind of shape at core 25 formation pin clamping holes, this is outstanding from the peripheral part of the longitudinal direction of pin clamping hole towards core to hold assembly 27, and leaves space 28 between the front end of hold assembly 27.

The core 25 of this form element 24 is through the bending machining camber, as shown in Fig. 4 (a).Simultaneously, curved shape is preferably fixed by carrying out heat treatment.Yet this is unbending to hold assembly 27.Also turning back along dotted line 29 bendings in the two ends of the longitudinal direction of form element 24 also is acceptable.What can also accept is, turns back for the ease of bending, shallow flute profile recess can be placed dotted line 29 parts.

The pin clamper 22 of Xing Chenging is made by the lamellar spring material of single rectangle by this way, the core of spring material is made the summit 30 that is bent to form arc, and pin clamper 22 has the triangle side shape, and it comprises a pair of sloping portion 31 that is positioned at 30 both sides, summit.The summit 30 that is bent to form arc have wherein this to hold assembly 27 from the outstanding shape of the peripheral part of the longitudinal direction of pin clamping hole.Because this does not pass through bending process to hold assembly 27, so it is outstanding on the direction identical with sloping portion.When pin 23 was inserted in the pin clamping hole, this was projected into the length among the peripheral groove 23a that for example bites into pin to hold assembly 27.

(user mode of example 1)

Fixator 21 occupation modes according to example 1 are as follows.That is to say, when pinning fixator 21, the leg-of-mutton base of pin 23 from pin clamper 22 is inserted into the pin clamping hole on summit 30.At this moment, when making this strain take place, insert pin 23, it is protruded in the pin clamping hole, and hold assembly is pushed open and the outside that arrives hold assembly 27.Because this is outstanding on the direction identical with sloping portion 31 to hold assembly 27, so can not present strong resistance to the insertion of described pin so far.Like this, when the peripheral groove 23a of pin 23 arrived the extrusion position of hold assembly 27, hold assembly 27 flexibly turned back to original-shape, and moves among the peripheral groove 23a of pin 23, and finishes the pinning process.

Because when hold assembly 27 moves among the peripheral groove 23a of pin 23, can send little ticktack, so can confirm to have finished the pinning process at an easy rate.For this reason, pinning fixator 21 reliably.In the fixator 21 that is in the pinning state, hold assembly 27 with the outstanding in the opposite direction state in pin 23 sides of extracting under, pin 23 will can not deviate from pin fixator 22 under the situation that state remains unchanged, because hold assembly 27 bites among the peripheral groove 23a.For this reason, even at pin clamper 22 or sell under 23 situations about being snarled, still can keep the pinning state, and can not take place for example owing to ornament falls the problem of losing that causes by hair for example or other material.

When hope finishes the pinning state of fixator 21, this end to sloping portion 31 of pin clamper 22 is pinched for example, between thumb and the forefinger, and on the direction of arrow shown in Fig. 4 (b) (direction of the spacing between the end of minimizing sloping portion 31), apply active force.By this operation, as shown in Fig. 4 (b), strain takes place in the more crooked mode in the summit 30 of pin clamper 22.

Show this aspect among Fig. 8 in greater detail.Fig. 8 (a) has shown the summit 30 that is in the pinning state, and Fig. 8 (b) has shown the summit 30 when finishing the pinning state.As shown in Fig. 8 (b), by so that the more crooked mode generation strain in summit 30 of pin clamper 22 can make this that hold assembly 27 is moved away from each other.Therefore, this leaves the peripheral groove 23a of pin 23 to hold assembly 27.For this reason, pin 23 is deviate from pin clamper 22 at an easy rate.

[example 2]

(process for making of example 2 and structure)

Comprise pin clamper 33 and the pin 23 identical according to the fixator 32 of example 2 with example 1.Pin clamper 33 is to utilize the form element 34 shown in Fig. 5 (b) to make.Form element 34 be by can carrying out bending process, and the material with elastic deformability is made.

In form element 34,, can form this to hold assembly 27 and space 28 by providing recess 26 in the mode identical with described form element before 24 at core.Yet, in form element 34, being provided with the expansion 35 that is used to constitute base part 37 at arbitrary end of longitudinal direction, it will be described below to some extent.In expansion 35, when the part 37 of structure base, formed pin through hole 36 in the part below being located immediately at summit 30.Because pin through hole 36 forms long ellipse on from left to right the direction in the drawings, so latch 23 can relatively move on direction from left to right.

By core bending machining camber, as shown in Fig. 5 (a), formed summit 30 and this is to sloping portion 31 with the longitudinal direction of this form element 34.In addition, belong to the expansion 35 of the end of sloping portion 31, can form a pair of base part 37 that overlaps each other by dotted line bending machining along Fig. 5 (b).What can also accept is, turns back for the ease of bending, shallow flute profile recess can be placed dotted portion.Described before pin through hole 36 is positioned in the part that is located immediately at the base part 37 below the summit 30.

In addition, this each front end to base part 37 has and makes it can not reach the length of the pedestal of another base part 37.Therefore, as shown in Fig. 6 (a), when finishing the pinning state of fixator 32, it can not form the obstacle to operation, and this operation impels the summit 30 of pin clamper 33 with more crooked mode generation strain.

As shown in Fig. 5 (b), formed auricula sheet 38 on the front end of an expansion 35 therein.With after described mode forms base part 37 so far, on the direction of another base part 37, be bent to form auricula sheet 38.Though it also is applied to auricula sheet shown in following each example, for the ease of along shown in the dotted line bending to turn back and shallow slot shape recess is placed auricula sheet 38 also be acceptable.By the bending forming of auricula sheet 38, these two base parts 37 can carry out being subjected under the state of relative sliding motion restriction each other in a longitudinal direction.

Though all is identical for described example 1 before with hereinafter described each example, but in this example 2, this is an acceptable also to the shape that hold assembly 27 has from pedestal to the top same widths, it especially preferably has the shape that diminishes gradually towards top width, as shown in Fig. 5 (b).

Hold assembly 27 is had under the situation of shape shown in Fig. 5 (b) at this, have the bigger width of base part (part shown in the width B) than the hold assembly in the form element 34 27 with summit 30 corresponding parts (by the part shown in the width A) in the form element 34.For this reason, when forming the summit 30 of pin clamper 33 by bending machining form element 34, bending force can not concentrate on by on the part shown in the width A.Therefore, as shown in Fig. 8 (b), can be equably with slight arc, from the whole the same degree far away of the part by shown in the width B that bends to its either side of the part shown in the width A.Summit 30 with this curved shape has presented for the superpower durability of carrying out pinning state end operation repeatedly, and this operation can cause the elastic compression distortion of the triangle side shape of pin clamper 33.

Hold assembly 27 is temporarily had under the situation of the shape from pedestal to the top same widths at this, the bending force in the bending machining of form element 34 can concentrate on and summit 30 corresponding parts, and this part bends to sharp-pointed arc.For this reason, as shown in Fig. 8 (c), it is less at this distance W between top of hold assembly 27 being compared with the situation among hereinafter described Fig. 8 (b).That is to say,, need impel pin clamper 33 that bigger compression takes place in order from the peripheral groove of pin 23, to remove this to hold assembly 27.Big compression have negative effect for the elastic deformability's on summit 30 persistence repeatedly.

(user mode of example 2)

Situation according to the user mode of the fixator 32 of example 2 and example 1 is identical, except next described some.That is to say that when pinning fixator 32, pin 23 passes pin through hole 36 from the leg-of-mutton base of pin clamper 33, is inserted into afterwards in the pin clamping hole on summit 30.Be in the pin 23 of pinning state and the motion of pin clamper 33 and on 2 o'clock, be subjected to mutual restriction, be i.e. the pin through hole 36 of the pin clamping hole on summit 30 and base part 37.For this reason, when pin clamper 33 did not rock around pin 23, the ornament that is in the pinning state can stably rock.

In addition, because these two base parts 37 are subjected to the mutual restriction of auricula sheet 38, so pin clamper 33 has higher structural strength.In addition, because these two base parts 37 are possible at the relative sliding motion of longitudinal direction, even so when auricula sheet 38 is provided, also not can as before described in the example 1 owing to there is interference to this strain of pin clamper 33 in pinning state end operation.

Fig. 7 is the perspective view that is in the fixator 32 of pinning state.

[modification of example 2]

In example 2, shown form element 39 also is an acceptable among use Fig. 6 (b).In form element 39, with described

form element

24 and 34 is opposite before, a pair of hold assembly 40 does not have the shape that narrows down gradually towards the top, but has from the pedestal width identical to the top.

[example 3]

(process for making of example 3 and structure)

As shown in Figure 10 (a) and 10 (b), according to the fixator 41 of example 3 comprise pin clamper 42 with example 1 in identical pin 23.Pin clamper 42 is to utilize the form element 43 shown in Fig. 9 to make.

Form element 43, according to carry out suitable technical process according to the identical mode of the described form element of example 1 24 by lamellar spring material to rectangle, punching technology process and forming for example, described spring material is feasible for the bending process process, and is made by the material with elastic deformability.44 of cores at form element 43 have formed a pin clamping hole 45.Be formed at the two ends of the longitudinal direction of core 44 according to the identical expansion 35 of the form element 34 of example 2, and in expansion 35, also formed pin through hole 36.

Simultaneously, revolution tab 46 is on non-longitudinal direction, and is outstanding from the part on the left side of the pin clamping hole 45 that is arranged in core 44 and right side.In addition, provide a pair of hold assembly 47, it is outstanding from revolution tab 46, thereby can protrude in the pin clamping hole 45 when upset is gone back on the core 44.Space 28 under the situation of space 49 and described form element 24 before is suitable, and it is located between this front end to hold assembly 47.In addition, on each revolution tab 46, be provided with auricula sheet 48.

By core bending machining camber, form summit 30 according to the mode identical and this is to sloping portion 31 with the situation of example 1 with the longitudinal direction of form element 43.In addition, belong to the expansion 35 of the end of sloping portion 31, can form a pair of base part 37 that overlaps each other by dotted line bending machining along Fig. 9.Turn back for the ease of bending, with shallow slot shape recess along shown in dotted line to place expansion 35 also be acceptable.Described before pin through hole 36 is positioned in the part that is located immediately at the base part 37 below the summit 30.This each front end to base part 37 has makes it can not reach the length of the pedestal of another base part 37.

In addition, this to the revolution tab 46 along shown in dotted line, the bending forming in the mode on the front that overlaps sloping portion 31 mutually.For the ease of bending turn back and with shallow slot shape recess along shown in dotted line place the revolution tab 46 also be acceptable.Because this bending forming, outstanding this revolution tab 46 kept a kind of its outstanding state on the direction of the core of pin clamping hole 45 to hold assembly 47 from this.Auricula sheet 48 is by locking onto on the sloping portion 31 at bending forming on the direction of sloping portion 31, and makes by auricula sheet 48 and respectively to turn round tab 46 and take place closely to contact with sloping portion 31.

(user mode of example 3)

For fixator 41 according to example 3, though at hold assembly 47 from revolution difference to some extent on the outstanding structure the tab 46, with regard to the operation of pinning fixator 41 with finish with regard to the operation of pinning state, its situation with example 1 is identical.

In addition, according to the mode identical with the situation of example 2, because be in the pin 23 and the pin clamper 42 of pinning state, its motion was subjected to mutual restriction on 2 o'clock, be the pin clamping hole 45 on summit 30 and the pin through hole 36 of base part 37, can stably rock so be in the ornament of pinning state.

[modification of example 3]

Though do not show in the accompanying drawings, but a modified example as example 3, according to the mode identical with the situation of example 2, also preferred by on base part 37 therein, direction with another base part 37 is bent to form the auricula sheet, and these two base parts 37 may take place to be subjected to mutual restriction under the state of relative sliding motion in a longitudinal direction.

[example 4]

(process for making of example 4 and structure)

As shown in Figure 11 (a), according to the fixator 50 of example 4 comprise pin clamper 51 with example 1 in identical pin 23.Because this fixator 50 is preferably applied to for example necklace, so pin clamper 51 and pin 23 respectively are connected on the necklace chain 52.

Pin clamper 51 is to utilize the form element 53 shown in Figure 11 (b) to make.Form element 53, according to carry out suitable technical process according to the identical mode of the described form element of example 1 24 by lamellar spring material to rectangle, punching technology process and forming for example, described spring material is feasible for the bending process process, and is made by the material with elastic deformability.Provide recess 26 by core 54, form this, and reserve the space 28 between it hold assembly 27 with a certain shape at form element 53.

With identical expansion 35 in the form element 34 according to example 2, it is formed at an end of the longitudinal direction of core 54, and has also formed pin through hole 36 in expansion 35.Simultaneously, be used to form the expansion 56 of hereinafter described vertical part 55, it is located at the other end of the longitudinal direction of core 54.Like this, a pair of auricula sheet 58 is outstanding on non-longitudinal direction, pass appointment in the fore-end of expansion 56 by the sweep shown in the dotted line 57.

By core bending machining camber, form summit 30 according to the mode identical and this is to sloping portion 31 with the situation of example 1 with the longitudinal direction of form element 53.In this example, the angle of bend on summit 30 is made into an acute angle, and ornament fixator 50 forms elongated shape.

Like this, the dotted line bending machining expansion 35 by along Figure 11 (b) can form the base part 37 with pin through hole 36.As shown in Figure 11 (a), the front end of base part 37 has makes it can not arrive the length of another sloping portion 31.Therefore, when finishing the pinning state of fixator 50, it can not form the obstacle to operation, and this operation impels the summit 30 of pin clamper 51 with more crooked mode generation strain.

Simultaneously, by on the vertex of a triangle direction of pin clamper 51, along shown in another expansion 56 of being bent to form of dotted line, it has formed vertical part 55.Turn back for the ease of bending, with shallow slot shape recess along shown in dotted line to place expansion 56 also be acceptable.Next, auricula sheet 58 bendings of the end of the vertical part 55 by making the sweep 57 of being located at appointment, and make it further crooked along dotted line at its front end, and what can form tubulose shelters parts 59, and its encirclement is inserted into the front end of the pin 23 in the pin clamping hole.

In addition, because fixator 50 forms elongated shapes, thus under its situation, the protuberance phenomenon that is hidden in the fixator below the clothes is arranged seldom as for example necklace, and impression and outward appearance are exhilarating.In addition, because the vertically existence of part 55, fixator 50 is stable.In addition because formed surround pin 23 front ends that insert in the pin clamping hole shelter parts 59, so can prevent from for example to handle carelessly fixator 50, sharp-pointed pin front end stabs out accidents such as wearer's finger or skin.

[example 5]

(process for making of example 5 and structure)

Also comprise pin clamper and the pin 23 identical according to the fixator 32 of example 5 with example 1.With regard to this example, for fear of the repetition of describing and illustrating, only explanation and description are used to make the

form element

60 or 61 of pin clamper.

As Figure 12 (a) with (b), according to the mode identical according to the described form element of example 1 24, carry out suitable technical process by lamellar spring material to rectangle, punching technology process and form first form element 60 and second form element 61 for example, described spring material is feasible for the bending process process, and is made by the material with elastic deformability.

In first form element 60, only heart part 62 forms pin clamping hole 45 therein.Be used to form the expansion 63 of pin clamper tab, it is located at arbitrary end of core 62 longitudinal directions, a pair of with the outstanding auricula sheet 64 of non-longitudinal direction, and all be located on the fore-end of each expansion 63 with the outstanding hold assembly that is rather narrow 65 of longitudinal direction.

When the pin fixator from form element 60, made according to this example,, form the summit and this is to sloping portion by core bending machining camber with the longitudinal direction of form element 60 according to the mode identical with the situation of example 1.Like this, by making expansion 63 along the dotted line 63a of Figure 12 (a) and bending makes on its front that overlaps sloping portion, thereby form pin clamper tab.Turn back for the ease of bending and also be acceptable along the dotted line setting shallow slot shape recess.By this bending process process, this has realized making it to protrude into state in the pin clamping hole 45 to hold assembly 65.Next by bending forming on the direction of sloping portion auricula sheet 64 is locked onto on the sloping portion, and make pin clamper tab and sloping portion take place closely to contact by auricula sheet 64.

In second form element 61, when comparing, do not comprise that this is unique differences to auricula sheet 64 with first form element 60.When the pin fixator made by form element 61 according to this example, the core of the longitudinal direction by bending machining form element 61 form summit and this to sloping portion after, by making the dotted line of expansion 63, so that it overlaps the mode bending on the sloping portion rear surface and forms pin clamper tab along Figure 12 (b).In this state, because pin clamper tab overlaps on the rear surface of sloping portion, so do not need to utilize auricula sheet etc. that it is not locked on the sloping portion.

[example 6]

(structure of example 6)

As shown in Figure 13 to 15, according to the fixator 50 of example 6 comprise pin clamper 66 with example 1 in identical pin 23.Pin clamper 66 is made of spring members 67 and clamper pedestal 68.

Spring material 67 forms by the silicon rubber with suitable stiffness and elastic deformability is molded, it has the triangle side shape that is formed by a pair of linear tilt part 70 that is positioned at 69 both sides, summit of summit 69and, and comprising that the summit is used to insert the pin clamping hole 71 of pin 23, the summit has the shape that bends to acute angle or arc.

Base part 73 has shape crooked on the direction on the base of the triangle side shape of mentioning before, it is by in this each vertical end portion to sloping portion 70, with the direction of the direction of insertion almost parallel of pin 23 on crooked vertical component 72 and forming.Between the front end of base part 73, leave certain space 74, but and formed supply and marketing 23 and be inserted into notch part 75 in the pin clamping hole 71.For the sloping portion in the spring members 67 70, can also have and wherein do not form base part 73, perhaps do not form the structure of base part 73 and vertical component 72.

Clamper pedestal 68 is fixed on this each sloping portion to sloping portion 70.Yet, can also only a clamper pedestal 68 be fixed therein on the sloping portion 70.Clamper pedestal 68 is plate-shaped members of being made by the hard material that can carry out bending machining, as shown in the figure in the relation of the fixed position of the reality of Figure 13 (b), it comprises base part 76, from the outstanding hold assembly 77 of base part, and a pair of revolution tab 78 outstanding on the vertical direction with respect to hold assembly 77.

Like this, clamper pedestal 68 is being connected under the state of sloping portion 70, is carrying out bending in the mode of surrounding sloping portion 70, clamper pedestal 68 can be fixed on the sloping portion 70 by making revolution tab 78.When the end portion of the clamping pedestal 68 on the front end of sloping portion 70 contrast to vertical component 72 when coming in contact, it can not move to the place more farther than its fixed position towards the front of sloping portion 70.Under the situation that does not form vertical component 72 or base part 73 on the spring members 67, the described a kind of suitable fixture of " embodiment " part fixes clamping pedestal 68 before can using.

Under described stationary state so far, the hold assembly 77 of clamper pedestal 68 is outstanding with the direction identical with sloping portion 70, and reaches the length that for example bites among the peripheral groove 23a that inserts the pin 23 in the pin clamping hole 71.

(user mode of example 6)

Situation according to the user mode of the fixator of example 6 and example 1 and example 2 is identical basically.

That is to say that when the pinning fixator, the triangular shaped base of the spring members 67 of pin 23 from pin clamper 66 is inserted in the pin clamping hole 71 on summit 69.During this time, when pushing hold assembly 77, insert pin 23, it is protruded in the pin clamping hole 71, project to the outside.Because this is outstanding on the direction identical with sloping portion 70 to hold assembly 77, so can not present strong resistance to the insertion of described pin 23 so far.Like this, when the peripheral groove 23a of pin 23 arrived the extrusion position of hold assembly 77, hold assembly 77 turned back to the home position, and moves among the peripheral groove 23a of pin 23, and finishes the pinning process.

Because when hold assembly 77 moves among the peripheral groove 23a of pin 23, can send little ticktack, so can confirm to have finished the pinning process at an easy rate.For this reason, pinning fixator reliably.In the fixator 21 that is in the pinning state, hold assembly 77 with the outstanding in the opposite direction state in pin 23 sides of extracting under, pin 23 will can not deviate from pin clamper 66 under the situation that state remains unchanged, because hold assembly 77 bites among the peripheral groove 23a.For this reason, even at pin clamper 66 or sell under 23 situations about being snarled, still can keep the pinning state, and can not take place for example owing to ornament falls the problem of losing that causes by hair for example or other material.

When hope finishes the pinning state of fixator, this end to sloping portion 70 of spring members 67 is pinched for example, between thumb and the forefinger, and on the direction of the spacing between the end that reduces sloping portion 70, apply active force.By this operation, as shown in Figure 14 (b), strain takes place in the more crooked mode in the summit 69 of spring members 67.The space of leaving between this front end to base part 73 74, it allows this strain.When space 74 disappeared, as shown in Figure 14 (b), by strain, pin 23 reached it and passes state by this hole that notch part 75 is formed.By this strain of spring members 67, this moves away from each other to hold assembly 77.Therefore, this leaves the peripheral groove 23a of pin 23 to hold assembly 77.For this reason, pin 23 is deviate from pin clamper 66 at an easy rate.

In addition, when the pinning fixator, pin 23 passes space 74 from the triangular shaped base of spring members 67, is inserted into afterwards in the pin clamping hole 71 on summit 69.Be in the pin 23 of pinning state and the motion of pin clamper 66 and on 2 o'clock, be subjected to mutual restriction, be i.e. the pin clamping hole 71 on summit 69 and base part 73.For this reason, when pin clamper 66 did not rock around pin 23, the ornament that is in the pinning state can stably rock.
