The utility model solves the problems of the technologies described above the technical scheme that adopts: the Tiebar structure of a kind of electric slicer or pull bar saw, comprise main tie and subtie, it is characterized in that: also comprise being sheathed on the pull bar positioning component of locating with front stall in main tie and the subtie end endoporus, described pull bar positioning component comprises:
One location lining is sheathed in main tie or the subtie end endoporus, and its sidepiece has a pin-and-hole, and the front end sidepiece of described main tie and subtie offers the through hole corresponding with described pin-and-hole;
One alignment pin, telescopically cross spacing are in positioning adapter, and its head is corresponding with the position of described pin-and-hole;
One spring is located between the inwall of the afterbody of alignment pin and positioning adapter, makes alignment pin have the trend that outwards ejects all the time described pin-and-hole;
One location push rod, can before and after be sheathed on actively in the positioning adapter, its inner end is provided with to cooperate with described alignment pin carries out spacing limit base, by promoting positioning mandril, the realization alignment pin stretches out pin-and-hole and front stall positions.
As improvement, described limit base be provided be ladder pattern distribution, with the third gear locating piece of transition face, match with locating piece in the bottom of described alignment pin, when alignment pin was limited in first grade of locating piece, the head of alignment pin was lower than positioning adapter; When alignment pin was limited in the second gear locating piece, the head of alignment pin stretched out the through hole that positioning adapter is arranged in pull bar, located with pull bar; When alignment pin was limited in the third gear locating piece, the head of alignment pin stretched out the through hole of pull bar, embedded in the front stall to position.
Improve again, described positioning adapter is to be involuted by upper lining and lower lining, upper lining and the involutory rear formation of lower lining can be for positioning mandril plant and the accommodating cavities that slides, form the pin-and-hole corresponding with described alignment pin at sidepiece, and formation cooperates spacing edge with the end face of main tie or subtie on the outer face.
At last, the lateral wall of described upper lining is provided with some cramps, and the sidepiece of described lower lining is provided with the corresponding pin of buckleing, upper lining and lower lining by cramp with buckle cooperating of pin and snap together.
Compared with prior art, the utility model has the advantage of: by at main tie and subtie the pull bar positioning component being set, so that pull bar and front stall can split fast, during connection, slightly be forced into as long as two holes on the front stall are put on two pull bars, just can finish assembling, very convenient.The utility model has not only reduced the cost of packing, so that volume has reduced 1/3rd, but also reduced transportation and deposited cost, the quantity that has increased transportation and deposited, so that the space that takies is few, portably use conveniently, more reasonable and practical on the structure, be adapted at the upper application of electric slicer or pull bar saw.

Fig. 1 is STRUCTURE DECOMPOSITION schematic diagram of the present utility model;
Fig. 2 ~ 4 are fundamental diagram of the present utility model.
The specific embodiment
Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of split-type pull bar, comprise main tie 1, subtie 2 and be sheathed on main tie 1 and subtie 2 end endoporus in the pull bar positioning component that positions with two holes of front stall 7, this pull bar positioning component is only by positioning adapter 3, alignment pin 4, spring 5 and positioning mandril 6 assemble, wherein positioning adapter 3 is sheathed in main tie 1 or the subtie 2 end endoporus, its sidepiece has a pin-and-hole 33, the front end sidepiece of main tie 1 and subtie 2 offers the through hole 11 corresponding with pin-and-hole 33, alignment pin 4 telescopically cross spacings are in positioning adapter 3, and its head is corresponding with the position of pin-and-hole 33; Spring 5 is located between the inwall of the afterbody of alignment pin 4 and positioning adapter 3, makes alignment pin 4 have the trend that outwards ejects all the time pin-and-hole 33; Positioning adapter 3 is to be involuted with lower lining 32 by upper lining 31, the lateral wall of upper lining 31 is provided with some cramps 31.1, the sidepiece of lower lining 32 is provided with the corresponding pin 32.1 of buckleing, upper lining 31 and lower lining 32 by cramp 31.1 with buckle cooperating of pin 32.1 and snap together, upper lining 31 can be for positioning mandril 6 plants and the accommodating cavity that slides with lower lining 32 involutory rear formation, form the pin-and-hole 33 corresponding with alignment pin 4 at sidepiece, and formation cooperates spacing edge 34 with the end face of main tie 1 or subtie 2 in the outer face; Positioning mandril 6 can be sheathed in the accommodating cavity of positioning adapter 3 front and back actively, its inner end is provided with to cooperate with alignment pin 4 carries out spacing limit base 61, limit base 61 is set to be the third gear locating piece of ladder pattern distribution, band is just like the chamfered transition face, make alignment pin 4 can between limit base 61, carry out slippage, the bottom of alignment pin 4 forms the annular lip 41 that matches with locating piece, when alignment pin 4 is limited in first grade of locating piece, such as Fig. 2, the head of alignment pin 4 is lower than positioning adapter 3, is used for packing into main tie 1 or subtie 2; When alignment pin 4 was limited in the second gear locating piece, such as Fig. 3, the head of alignment pin 4 stretched out the through hole 11 that positioning adapter 3 is arranged in main tie 1 or subtie 2, positioned with main tie 1 or subtie 2, was used for packing into front stall 7; When alignment pin 4 is limited in the third gear locating piece, such as Fig. 4, the head of alignment pin 4 stretches out the through hole 11 of main tie 1 or subtie 2, embed locating hole in the front stall 7, be fixedly connected with front stall 7 and position, so only need to promote positioning mandril 6, just can realize that the location of main tie 1 or subtie 2 and front stall 7 is fixed.
During installation, with main tie 1, subtie 2 inserts in the rocking bar hole, knob is screwed in and tightens, then the main tie 1 of the pull bar positioning component being packed into, in the end endoporus of subtie 2, promoting positioning mandril 6 makes alignment pin 4 be positioned at the second gear locating piece, with main tie 1, subtie 2 location, again main tie 1 is aimed in 7 liang of holes of the front stall in the nose assembly, the end of subtie 2, slightly be forced into, so that alignment pin 4 is positioned at the third gear locating piece, the head of alignment pin 4 stretches out the through hole 11 of main tie 1 or subtie 2, embeds in the front stall 7, be fixedly connected with front stall 7 and position, namely finish assembling.
