A pair of hang part 17,17 is arranged at the both sides of the 10b of guide main body portion and two sides of open-close lid of actuator guide portion 10 with the state erecting towards top.At the lower surface of two hang parts 17,17, be formed with respectively the inclined plane 17a tilting along the direction declining towards rear side.Also be formed with inclined plane 11c in the fore-and-aft direction substantial middle of open-close lid 11 accordingly with this two hang part 17,17.The inclined plane 17a of the inclined plane 11c of these open-close lid 11 sides and above-mentioned hang part 17 sides tilts along the direction rising towards rear side on the contrary.As shown in Figure 2, if under the closed condition of open-close lid 11, the both sides of the front frame 16b of portion of spring 16 with respect to the hang part 17,17 of left and right from downside hooking, the left and right sidepiece of this front frame 16b of portion is resisted against inclined plane 17a, 17a, and the central authorities of the front frame 16b of portion are resisted against the inclined plane 11c of open-close lid 11.The elastic force of spring 16 mainly acts on to (direction that open-close lid 11 is introduced towards rear side) towards the rear due to its curved shape, and therefore this front frame 16b of portion becomes the state between inclined plane 17a, 17a and the central inclined plane 11c that flexibly bites into left and right.Consequently, at open-close lid 11, except open-close lid 11 being acted on to the elastic force of the direction of introducing towards the rear being produced by spring 16, the elastic force that presses down direction of the front frame 16b of portion and the elastic force that presses down direction of inclined plane 11c based on central that also open-close lid 11 are acted on inclined plane 17a, 17a based on left and right, be locked as closed condition by these elastic force by open-close lid 11.
The in the situation that of present embodiment, be to form to the position of squeezing into the head side of squeezing into part of supplying with in path 5a by the set positions of the fore-and-aft direction of inclined plane 11c.Therefore, utilize locking mechanism 12 to put on the power of closing (elastic force) of the rear side of open-close lid 11, being applied in via inclined plane 11c to (near the head guide portion of nail bin 4) near squeezing into the head side of squeezing into part of supplying with in path 5a, even if also can maintain efficiently firm closed condition in the time that the head based on actuator 2b impacts.This rear side closure power applies position and in Fig. 2, marks the symbol of P1 and represent.
Except this locking mechanism 12, squeezing into squeezing into direction front side and approaching the position of exit wound of bullet 5b of guide portion 5, form and have side closure portion 20,20 before pair of right and left.In the present embodiment, front side closure portion 20,20 is set at than to squeezing into the forward slightly side of the leading section of squeezing into part of supplying with in path 5a.Therefore, apply position P2 and dispose front side closure portion 20,20 applying front side closure power that position P1 (inclined plane 11c, the position of hang part 17) separates sufficient interval L with respect to the rear side closure power based on above-mentioned locking mechanism 12.Utilize this front side closure portion 20,20, open-close lid 11 is mainly that anterior (exit wound of bullet 5b side) is locked as closed condition reliably with respect to the 10b of guide main body portion.The lid side holding section 11d of the front side closure portion 20 passage side holding sections 18 by the 10b of guide main body portion side and open-close lid 11 sides forms.Passage side holding section 18,18 is arranged at respectively the front of sidepiece and the above-mentioned hang part 17,17 of guide main body portion 10.As shown in Figure 3, overlook observation two passage side holding sections 18,18 and do not expose towards the side of the 10b of guide main body portion, and as shown in Fig. 2 and Fig. 4, be set to observe from the side the height dimension of the degree of giving prominence to a little with respect to the upper surface of open-close lid 11.
Also be formed with passage side inclined plane 18a, 18a in the lower face side of this two road side holding section 18,18.Two passage side inclined plane 18a, 18a also tilt along the direction declining towards rear side in the same manner with the inclined plane 17a of rear side.
With this two passage side holding section 18,18 accordingly, be provided with and cover side holding section 11d, 11d at the outstanding state in Yi Chao side, the both sides of open-close lid 11.As shown in Figure 3, two lid side holding section 11d, 11d with the size of the degree do not exposed towards the side of the 10b of guide main body portion outstanding formation of sidepiece to open-close lid 11.In addition, as shown in Figure 2, the height dimension of two lid side holding section 11d, 11d to equate with the thickness of slab of open-close lid 11, forms than 18 lowlands, passage side holding section.
Upper surface at this two lid side holding section 11d, 11d is formed with respectively inclined plane 11e.Two inclined plane 11e, 11e are with the angle identical with the inclined plane 18a of passage side holding section 18 (direction declining towards rear side) inclination in the same direction.Therefore, as shown in Figure 2, under the closed condition of open-close lid 11, the inclined plane 11e that is formed as covering side respectively with the inclined plane 18a of the passage side of left and right, the state of 18a sliding-contact.And, because the elastic force of spring 16 is along the directive effect of introducing towards rear side in open-close lid 11, therefore this elastic force is as the elastic force effect of closing the direction of open-close lid 11 by the sliding-contact effect of two inclined plane 18a, 11e.
Near the upper face center of open-close lid 11 with towards above the state that erects be provided with pushing wall portion 19.This pushing wall portion 19 brings into play function in the time of open-close lid 11 unlimited.To be narrated in the back this pushing wall portion 19.
Open-close lid 11 is opened wide via the state of Fig. 5 as shown in Figure 6 from the closed condition shown in Fig. 2～Fig. 4.As shown in Figure 5, when by opening/closing lever 15 during towards unlocked position side (the erecting direction) rotating operation of top, spring 16 entirety are carried out displacement towards front side, result, the front frame 16b of portion of spring 16 departs between inclined plane 17a, the 17a of hang part 17,17 and the inclined plane 11c of open-close lid 11 sides, and this state of nipping is disengaged.Thus, the closed condition of the open-close lid 11 based on this locking mechanism 12 is unlocked.
Afterwards, when by opening/closing lever 15 during further towards release side rotating operation, the front frame 16b of portion of spring 16 further carries out displacement to front side, with pushing wall portion 19 butts of open-close lid 11.Keep this butt state constant, opening/closing lever 15, towards release side rotating operation, is pushed to open-close lid 11 thereby squeeze into direction front side via spring 16 courts.
The bolster 14 that supports open-close lid 11 with respect to guide main body portion 10 is long slot bore shape, and this bolster 14 is inserted through the support holes 11b tilting along the direction declining towards rear side.Therefore,, by utilizing spring 16 to push open-close lid 11, this open-close lid 11 carries out displacement and carries out displacement towards opening direction on one side towards squeezing into direction front side on one side.Fig. 5 represents the state in this stage.As shown in Figure 5, when open-close lid 11 is pushed by spring 16 and when squeezing into direction front side and carry out displacement, lid side holding section 11d, 11d are disengaged with respect to the fastening state of passage side holding section 18,18, and lid side holding section 11d, 11d depart from the front side closure portion 20,20 of left and right.
So, utilize the unlocking operation of opening/closing lever 15, locking mechanism 12 is unlocked, afterwards, open-close lid 11 is pushed by spring 16 and carries out displacement towards squeezing into direction front side, can, after front side closure portion 20,20 is disengaged, this open-close lid 11 be opened wide towards top thus.Fig. 6 represents the opening-wide state of open-close lid 11.
Close open-close lid 11 from this opening-wide state, make this open-close lid 11 be positioned at the upper surface of guide main body portion 10 along the upper surface of guide main body portion 10.As shown in Figure 6, because the front frame 16b of portion at spring 16 is from the state that departs from of pushing wall portion 19, the elastic force of spring 16 is not towards front side and open side and act on open-close lid 11, therefore this open-close lid 11 can with the state of the upper surface butt of guide main body portion 10 under be fixed.Afterwards, opening/closing lever 15 is rotated along the direction of falling down towards downside, and the front frame 16b of portion that makes the spring 16 departing from turns back to the inclined plane 17a of left and right hang part 17,17, between the inclined plane 11c of 17a and open-close lid 11 sides, under this state, by opening/closing lever 15 is further rotated towards locking side, this front frame 16b of portion is bitten between inclined plane 17a, 17a and inclined plane 11c.The front frame 16b of portion by spring 16 flexibly nips between inclined plane 17a, 17a and inclined plane 11c, the elastic force of this spring 16 is along the directive effect of introducing open-close lid 11 towards rear side in this open-close lid 11, and, along the directive effect that pushes this open-close lid 11 towards the upper surface of guide main body portion 10 in this open-close lid 11.
Utilize the rotating operation towards locking side of opening/closing lever 11 that open-close lid 11 is introduced towards rear side, lid side holding section 11d, the 11d of front side closure portion 20,20 bite into the downside of passage side holding section 18,18 thus, this front side closure portion's 20,20 elastic force by spring 16 and flexibly being engaged.When current side closure portion 20,20 is flexibly engaged, inclined plane 11e, the 11e of lid side holding section 11d, 11d respectively with the inclined plane 18a sliding-contact of passage side holding section 18.By this sliding-contact effect, the elastic force of spring 16 acts on open-close lid 11, the particularly front side of open-close lid 11 along the direction (direction pushing towards guide main body portion 10) of closing open-close lid 11.So the elastic force that, utilizes spring 16 in the front side from open-close lid 11 to the roughly whole region of rear side with respect to guide main body portion 10 these open-close lids 11 of pushing and make this open-close lid 11 become closed condition.
According to the driver 1 of the present embodiment forming like that above, different from the locking mechanism 12 that open-close lid 11 is locked as to closed condition, be provided with in the front side of driver 1 this open-close lid 11 is remained to the front side closure portion 20,20 that closes portion's state.Therefore, cause the locking mechanism 12 of obstruction to be disposed at the angle operation that is for example easy to fight each other and squeeze into direction rear side, and squeeze into direction front side (exit wound of bullet 5b side) utilize before side closure portion 20,20 can reliably open-close lid 11 be remained to closed condition, can prevent thus particularly the floating of front side of this open-close lid 11, squeeze into part guiding function thereby can bring into play reliably.
In addition, elastic force by making spring 16 is along making open-close lid 11 towards the directive effect of squeezing into the displacement of direction rear side in this open-close lid 11, can make this elastic force as playing a role towards the elastic force of the direction application of force of closing open-close lid 11 via inclined plane 18a, the 11e of front side closure portion 20,20.Thus, in the time utilizing locking mechanism 12 that open-close lid 11 is locked as to closed condition, also can not operate especially and make it bring into play reliably function for front side closure portion 20,20, open-close lid 11 being spreaded all over to open-close lid 11 entirety and remain closed condition.
And then, according to present embodiment, due in the time that opening/closing lever 15 courts are opened to side operation, locking mechanism 12 is unlocked, and the fastening state of front side closure portion 20,20 is disengaged, thereby can open open-close lid 11, therefore can not operate especially and only open open-close lid 11 with shirtsleeve operation for front side closure portion 20,20, thus, can improve and carry out particularly the treatability (maintainability) of squeezing into this operation of squeezing into part of stopping up in path 5a and squeeze into guide portion 5 in the case of removing.
In addition, side closure portion 20,20 before this forward slightly side of the ratio the longest applicable leading section of squeezing into part of squeezing into guide portion 5 disposes, its front side closure power apply position P2, and rear side closure power based on being disposed near the locking mechanism 12 side of squeezing into part head apply between the P1 of position, be set with fully large interval L.Like this, due to open-close lid 11 is mainly that the close power of rear side utilization based on locking mechanism 12 is locked into closed condition, the front side that is mainly open-close lid 11 utilizes the power of closing based on front side closure portion 20,20 to be locked into closed condition, therefore also identical with rear side for the region of the particularly front side of open-close lid 11, can be locked into reliably closed condition.Therefore, there is interference etc. and be applied in impact even if squeeze into part in the particularly front side of open-close lid 11, also open-close lid 11 can be locked in reliably to closed position, can squeeze into more reliably thus guiding the elimination of part and squeeze into mistake.
In addition, for front side closure portion 20,20, because lid side holding section 11d, 11d and passage side holding section 18,18 are arranged in the scope of exposing not significantly in width and the thickness of slab direction (short transverse) of the 10b of guide main body portion, therefore do not damage the workability of beating angle etc. of this driver 1.
And then, be provided with pushing wall portion 19 at the upper surface of illustrative open-close lid 11, when by opening/closing lever 15 during towards unlocking direction rotating operation, the front frame 16b of portion of spring 16 and this pushing wall portion 19 butts, by rotating operation opening/closing lever 15 under this butt state, this open-close lid 11 carries out displacement along the direction of floating from the 10b of guide main body portion.Therefore, user can easily open wide open-close lid 11 afterwards.
In addition, according to illustrative open-close lid 11, due to this squeeze into direction front side and utilize before side closure portion 20,20 can be locked as reliably closed condition, therefore utilize this open-close lid 11 also can open wide exit wound of bullet 5b, can successfully block up thus the operations such as nail.
Can carry out various changes to embodiment discussed above.For example, though use from the side and observe along the structure of the spring of the direction bending towards upside projection exemplified with spring 16, also can use edge towards the spring of the direction bending of lower convexity or be formed as observing from the side the not spring of upper and lower bending smooth rectangle framework.
In addition, also can omit the inclined plane 17a of the hang part 17 in locking mechanism 12.By the front frame 16b of portion of spring 16 being resisted against to the inclined plane 11c of open-close lid 11 sides, can make the elastic force of this spring 16 towards the directive effect of closing.
In addition, also can omit pushing wall portion 19.
And then, as driver 1, though exemplified with the nailing machine of compressed air type, can be suitable for too for other driver of tacker, the bolt beating machine etc. of gas combusion-type.
