The specific embodiment

Please cooperate and consult Fig. 1 and Fig. 2, be the selected example structure of the utility model shown in the figure.

The utility model provides a kind of saw blade clamp structure, it is to form section by a board member 11 doublings generally to be the kenel that mouthful word removes a following horizontal shape, so that this board member 11 is formed with the linkage section 13 that two symmetrical side plates 12 and connect this two side plate 12, and between the inner edge wall of this two side plate 12, be formed with an accommodation space, these two side plates, 12 1 ends are formed with can be for connecing the bare terminal end 14 of establishing a saw blade 21, these two side plates, 12 other ends then are formed with and can establish connecing of a lever 31 and establish end 15 for connecing, and are provided with a saw blade fixing hole 16 that runs through this two side plate 12 in this bare terminal end 14 between 15 with connecing to establish to hold.

Be formed with the short slot 22 that one day, these bare terminal end 14 directions were offered on the root of this saw blade 21, this short slot 22 is formed with an opening 221 and a clamping section 222, and be provided with a perforation 23 in addition in the clamping section 222 of contiguous this short slot 22 is other, and these lever 31 inside have one and can ccontaining this board member 11 connect the holding part (not shown) of establishing end 15, and are equipped with the locating hole 32 of at least one this holding part of connection in these lever 31 sides.

This board member 11 is in be provided with two clamping parts 17 that are relative convex near the inner edge wall of this bare terminal end 14, and establish end 15 inner edge wall and be provided with two abutting parts 18 that are relative convex in connecing near this, and be provided with at least one lever fixing hole 121 (present embodiment is respectively to be provided with a lever fixing hole 121 in these abutting part 18 both sides) that runs through this two side plate 12 in these abutting part 18 sides, more be provided with two limiting sections 19 that are relative convex on the inner edge wall of end between 15 and connect to establish between this bare terminal end 14 and this, wherein, the height of projection A of each limiting section 19 and abutting part 18, B is identical, and greater than the height of projection C of this clamping part 17.

Please arrange in pairs or groups again and consult Fig. 3～Fig. 5, when connecing of the utility model saw blade clamp structure established end 15 when being located in the holding part of these lever 31 inside, this connects the lever fixing hole of establishing on the end 15 121 will be corresponding mutually with the locating hole 32 on this lever 31, and utilize a lock member (not shown) to wear again, this is connect establishes end and 15 is located in this lever 31 inside, and connect two set on the inner edge wall of establishing end 15 relative abutting part 18 designs by this, can make when this connects and establish end 15 and be locked on this lever 31 when inner, be positioned at this and connect the mutual butt of two abutting parts, 18 meetings of establishing end 15, can be maintained fixed and make this connect the distance of establishing between end 15 inner edge walls, effectively to avoid causing the distance of these bare terminal end 14 inner edge walls too small when end 15 is subjected to lock member locking, insert smoothly and influence saw blade 21 because of this connects to establish.

At this moment, because this two side plate 12 is to be subjected to this lock member roof pressure, and and then the limiting section 19 that forces 12 of this two side plates and this abutting part 18 to have identical height of projection also will connect airtight mutually, thus, the operator can be inserted these saw blade 21 roots by this bare terminal end 14, and by the clamping section 222 of these saw blade 21 roots and with the mutual butt of the ora terminalis of this limiting section 19, so as to reaching saw blade 21 effect of location fast, and when the mutual butt of the clamping section 222 of these saw blade 21 roots and this limiting section 19, perforation 23 on these saw blade 21 roots will be corresponding mutually with the saw blade fixing hole 16 on this board member 11, can wear for another lock member (not shown), to make the clamping part 17 corresponding joints on these bare terminal end 14 inner edge walls and to reach the effect of fixing this saw blade 21, and by this clamping part 17 is to be convex shape equally, therefore the operator only need slightly lock this lock member and establish action, can force the clamping part 17 in this bare terminal end 14 fast this saw blade 21 to be carried out the action that a folder is pulled, and can significantly reduce the time of operator when locking saw blade 21.

What this must specify be, saw blade clamp structure of the present utility model in practice when cutting work, please continue to consult Fig. 5, because the root of this saw blade 21 is to be placed in 12 of two side plates of this bare terminal end 14, and replace mutually with the knife back and this linkage section 13 of these saw blade 21 roots, make the operator whereby when carrying out cutting action, this saw blade 21 can effectively be restricted in the bare terminal end 14 of this two side plate 12, can produce skew to avoid this saw blade 21 when carrying out cutting action.

Then please continue to consult Fig. 6, be another embodiment aspect of the present utility model, it is with the difference of the foregoing description: this board member 11 is to be formed with two symmetrical side plates 12 and the linkage section 13 that is connected this two side plate 12 through doubling equally, and in its bare terminal end that is constituted of the outer surface upper edge of this two side plate 12 and connect to establish and be concaved with a plurality of recesses respect to one another between the end, so that this board member 11 is in the clamping part 17 that is relative convex near formation on the inner edge wall of its bare terminal end 14, then be formed with the abutting part 18 that is relative convex in connecing near this to establish on end 15 the inner edge wall, and be formed with two limiting sections 19 that are relative convex on the inner edge wall of holding between 15 connecing between this bare terminal end 14 and this to establish.

And saw blade clamp structure of the present utility model does not limit and need be installed among which kind of lever, and as shown in Figure 7, the connecing of the utility model saw blade clamp structure established end 15 can be in order to be installed among the slightly crooked lever 31a of a handle body; For another shown in Figure 8, the connecing of the utility model saw blade clamp structure established end 15 and can be among the lever 31b of strip in order to be installed in a handle body certainly, therefore, every this lever 31 is provided with and can corresponding holds the holding part person that connecing of the utility model saw blade clamp structure established end 15, should be equivalent embodiment of the present utility model.

The utility model saw blade gripping structure by above-mentioned member forms has the following advantages:

1. the utility model is to utilize a board member doubling is formed, therefore have simple in structure, Characteristics easy to manufacture and with low cost.

2. the utility model connects abutting part design set on the inner edge wall of establishing end by this, can Make when this connects and establish termination and be located at this lever when inner, be positioned at this connect two abutting parts of establishing end will be mutual Butt is established end and is subjected to lock member when locking to produce distortion because this connects effectively avoiding, and causes this folder The situation of holding the opening expansion of end takes place.

3. the utility model is by the design of this limiting section, and makes the operator can be by this saw blade root The mutual butt of ora terminalis of this limiting section of clamping Duan Eryu of section, and so as to reaching this saw blade of quick location The effect of position.

4. the utility model is to be equally convex shape by this clamping part, so the operator only need omit This lock member locked establish action, can force clamping part in this bare terminal end fast to this saw Sheet carries out the action that a folder is pulled, and significantly reduces the time of operator when the locking saw blade.
