In first gear 2 and it is offset to multiple the second bearing pins 22 as bending part is additionally provided with the position of the first bearing pin 21, preferably
Ground, bearing pin 21,22 is all roller bearing, to reduce the frictional resistance between bearing pin 21,22 and reinforcing bar 6 in 6 bending of reinforcing bar.Ability
Field technique personnel can also use other and feasible bearing pin as needed, as long as its friction between reinforcing bar 6 can be reduced
Resistance.It is not difficult to find out from Fig. 1, in bend reinforcement 6, one end of reinforcing bar 6, which is resisted against, is fixed on consolidating on fixed support 1
Determine on baffle plate 5, the position that reinforcing bar 6 bends is resisted against on the first bearing pin 21, the other end of reinforcing bar 6 is driven by the second bearing pin 22
Bend it.It is fixed in order to prevent reinforcing bar 6 to be subjected to displacement in BENDING PROCESS in optimal technical scheme of the present utility model
The groove 51 of reinforcing bar 6 can be accommodated by being additionally provided with baffle plate 5.It will be readily appreciated by those skilled in the art that each second pin
When the bearing pin 21 of axle 22 and first coordinates, all the reinforcing bar 6 of a model can at least be bent.Further, art technology
Personnel can also as needed by fixed dam 5 be arranged to can horizontal direction is moved along along Fig. 1 structure, can by the movement
Matching fixation is carried out to the reinforcing bar 6 of different-diameter.
As shown in Fig. 2 the second bearing pin 22 can also be arranged to movable part by those skilled in the art as needed,
Multiple pin shaft holes 23 are set on one gear 2, the second bearing pin 22 is then inserted by different pin shaft holes according to the diameter of different reinforcing bars 6
In 23.
With continued reference to Fig. 1, second gear 3 is connected with one end of handle 4 so that operating personnel can pass through the band of handle 4
Dynamic second gear 3 is rotated, and then drives first gear 2 to rotate by second gear 3.In preferred embodiment of the present utility model
In, the first spine for being provided with and being matched with first ratchet 31 on the first ratchet 31, fixed support 1 is additionally provided with second gear 3
Pawl 11.The first ratchet 31 and the first ratchet 11 after occlusion make second gear 3 to rotate in one direction, it is to avoid in steel
Reinforcing bar 6 produces the phenomenon of displacement during regulation handle 4 during muscle 6 is bent.
Further, although do not showed that in figure, but in second gear 3 second ratchet and the second ratchet can also be set,
In assembled state, one in the second ratchet and the second ratchet and second gear 3 are coaxial fixed, another and handle 4
It is coaxial fixed so that handle 4 can only be rotated around a direction of second gear 3, and then operating personnel are shifted onto by handle 4
During terminal, only handle 4 need to be gone to original position in reverse direction.Those skilled in the art can also be as needed by
One in two ratchets and the second ratchet is arranged on second gear 3, and another is arranged on handle 4.
Further, although do not showed that in figure, but in preferred embodiment of the present utility model, first gear 2
The pointer for being provided with scale, fixed support 1 and pointing to the scale being circumferentially equably provided with, can be read with will pass through the pointer
Go out the angle that first gear 2 is turned over, improve the precision of the bending angle of reinforcing bar 6.Or those skilled in the art can also basis
Need to be uniformly arranged scale along the circumference of first gear 2 on fixed support 1, pointer is set in first gear 2.
The operation principle of the present utility model for holding bending apparatus manually is described in detail below.
Exemplary, it is assumed that the ratio between radius of first gear 2 and second gear 3 is R：R=4:1, then F1* L=F2* r, F2*
R=F3*d.In formula, F1For thrust of the people to handle 4；F2For the engagement force between the gear 3 of first gear 2 and the 3rd；F3For second
Active force of the bearing pin 22 to reinforcing bar 6.
F can be tried to achieve by above-mentioned formula3=α F1(α=L*R/ (d*r) herein, according to R:R=4:R=4r knowable to 1, therefore α=
4L/d), therefore F can be drawn3With F1Between multiple proportion.Therefore it is of the present utility model manually hold bending apparatus can be significantly
Save manpower.Exemplarily, L=360mm is worked as, during d=60mm, according to F3=4L/d, so that it may to obtain F3=24F1。
It will be appreciated to those of skill in the art that d actual size is cut between the first bearing pin 21 and the second bearing pin 22
The length of line, in preferred embodiment of the present utility model, because the radius of bearing pin 21,22 and reinforcing bar 6 is smaller and for side
Just calculate, d values are the distance of shaft centers between the first bearing pin 21 and the second bearing pin 22 shown in Fig. 1.
Therefore, of the present utility model the length of handle can not only be reduced by holding bending apparatus manually, also facilitate the behaviour of personnel
Make, and the bending angle of reinforcing bar can accurately be controlled.
So far, combined preferred embodiment shown in the drawings describes the technical solution of the utility model, still, this
Art personnel are it is easily understood that protection domain of the present utility model is expressly not limited to these embodiments.
On the premise of principle of the present utility model, those skilled in the art can make equivalent change to correlation technique feature
Or replace, the technical scheme after these are changed or replaced it is fallen within protection domain of the present utility model.
