The specific embodiment
Seeing also Fig. 1 to Fig. 5, is the selected example structure of the utility model shown in the figure.
The improved tool construction of present embodiment comprises:
Two levers 1, this two lever 1 are to articulate with a lever pivot 12, this two lever 1 pin member 11 that stretched through respectively, and this two pin member 11 is parallel to this lever pivot 12, and this two pin member 11 is for moving axially in two levers 1 after the application of force.This two pin member 11 has big footpath section 111 and one a path section 112 respectively, and the external diameter of this big footpath section 111 is big than the external diameter of this path section 112, and this path section 112 is to pass this lever 1, and an end that stretches out this lever 1 has a block piece 14,140.In the present embodiment, the form of the big footpath section 111 of this pin member 11 is cylindric, and the cross section of the path section 112 of this pin member 11 has two length portions 113 and two weak point portions 114, the spacing that this two length portion is 113 has one first length 1131, and the spacing of 114 in this two weak points portion has one second length 1141, and this first length 1131 is long than this second length 1141.
One tool heads 2, it is made up of two holders 21, this two holder 21 articulates with a head pivot 22, and the lever pivot 12 of this lever 1 has a distance with the position of the head pivot 22 of this tool heads 2, and the below of this tool heads 2 has an insertion section 23 respectively, this insertion section 23 has an embedded groove 24, this embedded groove 24 has an opening 25, and the width of this opening 25 is less than the external diameter of the big footpath section 111 of the pin member 11 of the internal diameter of this embedded groove 24 and this lever 1, and, be hubbed at the big footpath section 111 of the pin member 11 of this two lever 1 under normal conditions for the embedded groove 24 of two insertion sections 23 of this tool heads 2 greater than the external diameter of the path section 112 of this pin member 11.In addition, the width of the opening 25 of the insertion section 23 of this tool heads 2 is less than first length 1131 of these pin member 11 path sections 112, and greater than second length 1141 of these pin member 11 path sections 112.
Contiguous this this two lever 1 of lever pivot 12 places respectively has a lever anchor point 13, for this two levers, 1 certain closed orientation.And two insertion sections 23 of this tool heads 2 also respectively have a head anchor point 26, for these tool heads 2 certain closed orientation.
The end place of the path section 112 of the pin member 11 of this lever 1 is provided with a block piece 14, and this block piece 14 is ends that screw togather the pin member 11 path sections 112 of this lever 1 that stretches through.Be provided with a spring 15 between this block piece 14 and 1 of this lever, the two ends of this spring 15 are supported respectively under the pressure of this block piece 14 and this lever 1, can reset to the state that places under big footpath section 111 normalities of this pin member 11 in this lever 1 after being pressed for this pin member 11.
In the present embodiment, the part that the path section 112 that other has a switch plate 16 to be located at this two pin member 11 stretches through this lever 1 back and protrudes, this switch plate 16 has a press surface 161 in the stage casing of 11 of this two pin members, one of them of this two block piece 14 is provided with a holding part 141, this holding part 141 has a stopper 142, and 16 pairs of this switch plates should block piece 14 holding part 141 be provided with a clip engine part 162, and contiguous these clip engine part 162 places are provided with a drive portion 163.
According to the structure of present embodiment, when desire was changed the tool heads 2 of different purposes, this two lever 1 and 2 need of this tool heads can implement to change operation under closure state.The user utilizes the drive portion 163 of this switch plate 16 and switch plate 16 is passed to the location, the clip engine part 162 of switch plate 16 was placed in the holding part 141 of this block piece 14, as long as the user depresses the press surface 161 of this switch plate 16, the clip engine part 162 of its switch plate 16 can prop up the stopper 142 of the holding part 141 of this block piece 14, moves axially and drive this two pin member 11 simultaneously.The big footpath section 111 of two pin members 11 was gone out from lever 1 slippage, and the short portion 114 that makes the path section 112 of pin member 11 aims at two openings 25 of this tool heads 2 respectively, and former tool heads 2 is broken away from from lever 1, make two insertion sections 23 of another tool heads 2 can insert again in this two lever 1, and the path section 112 of the pin member 11 of this two lever 1 embed in two embedded grooves 24 of this tool heads 2.Afterwards, decontrol two pin members 11 again, and the big footpath section 111 of two pin members 11 is embedded in two embedded grooves 24 of this tool heads 2, and finish the replacing of this tool heads 2.
By the explanation of the foregoing description as can be known, the utlity model has following advantage:
1, it is by the distance between the head pivot of the lever pivot of lever and tool heads, and the pivot joint of the embedded groove of the pin member of lever and tool heads, and has labour-saving double lever structure.Moreover when changing tool heads, only with hand is pushed the pin member of lever, can change the tool heads (for example scissors, pliers etc.) of different purposes easily, need not any instrument auxiliary, reach the use effect of quick assembling tool head and lever.
2, because a switch plate is located at the pin member of two levers, the user only needs the press surface of push switch medium film section can depress two pin members simultaneously, and is convenient to change tool heads.
3, because a switch plate is located at the pin member of two levers, and an end of two pin members is respectively in conjunction with a block piece, one of them of two block pieces is provided with a holding part, holding part has a stopper, and switch plate is provided with a clip engine part to holding part that should block piece, this clip engine part be stopper in this block piece, make switch plate can limit the opening and closing movement of two levers, when not using, guarantee that two levers do not open arbitrarily and cause danger for instrument.
4, two insertion sections that are tool heads respectively have a head anchor point, are convenient to the user when changing tool heads, make the certain closed orientation of tool heads.
5, respectively have a lever anchor point at contiguous this this two lever of lever pivot place, be convenient to the user when changing tool heads, make two levers be positioned to change smoothly the position of tool heads really.
6,, and when changing different tool heads, has more security because the form of the path section of the pin member of lever is flat column, and tool heads and lever only can could be assembled, and just the two is limited under the special angle when closure state.
Certainly, still there are many examples in the utility model, therebetween the only variation on the details.See also Fig. 6 to Fig. 7, it is second embodiment of the present utility model, wherein difference is, each lever 1A is respectively equipped with a shell fragment 17A, and the end place of the contiguous big footpath section 111A of this pin member 11A has a cephalic par 115A, this shell fragment 17A is the cephalic par 115A that presses on this pin member 11A, and the big footpath section 111A of this pin member 11A of slippage can reply the position in this lever 1A again for pushed the back by the application of force.Present embodiment still can reach all effects that first embodiment is had.
See also Fig. 8, it is the 3rd embodiment of the present utility model, and wherein difference is, the form of the big footpath section 111B of the pin member 11B of this lever 1B is cylindric, and the form of this path section 112B is all cylindric.Present embodiment is when changing the tool heads 2B of different purposes, need not be in specific folding angle, both tool heads 2B and lever 1B need not singly change under closure state, and the pin member 11B that the user only need depress lever 1B can do the replacement of tool heads 2B, has the convenience in the use.In addition, present embodiment still can reach all effects that first embodiment is had.
