For a kind of combination wrench.
The purpose of the present invention is what is be achieved through the following technical solutions：
A kind of combination wrench, including：Pinch bar, fixing card, ratchet shape groove, pillar, metal bar, resetting spring and turn
Disk, the front end of the pinch bar are equipped with ratchet shape groove, and turntable is arranged in the pinch bar of ratchet shape groove lower part, pacifies on turntable
Equipped with six roots of sensation pillar, in six apexes of a regular hexagon, each pillar is equipped with one for the position distribution of six roots of sensation pillar
Metal bar is vertical with the pillar where it, and the position that adjacent two metal bars are installed on pillar is one high and one low；In metal bar
Afterbody be provided with groove, is equipped with resetting spring in groove, one end of resetting spring is connected with metal bar, the other end of resetting spring and
Pillar is connected, and fixing card and turntable be located at same level, and fixing card is for fixing turntable, in the other end of pinch bar,
Mirror image is provided with fixing card, ratchet shape groove, pillar, metal bar, resetting spring and turntable.
The present invention can realize the screw-nut that only spanner can be loaded and unloaded with one multiple models, and simple to operate
Fast.It need to only adjust and once pull the size of mouth and can be carried out continuously ensuing tripping action, it is not necessary to manually adjust halfway
Pull the size of mouth.

Embodiment
Below in conjunction with attached drawing, the present invention is described in further detail：The present embodiment using technical solution of the present invention as
Under the premise of implemented, give detailed embodiment, but protection scope of the present invention is not limited to following embodiments.
As shown in Fig. 1~Fig. 7, a kind of combination wrench involved by the present embodiment, including：Pinch bar 1, fixing card 2, spine
Wheel shape groove 3, pillar 4, metal bar 5, resetting spring 6 and turntable 7, one end (front end) of the pinch bar 1 are equipped with ratchet shape groove
3, turntable 7 is arranged in the pinch bar 1 of 3 lower part of ratchet shape groove, and six roots of sensation pillar 4, the position of six roots of sensation pillar 4 are provided with turntable 7
Six apexes for being distributed in a regular hexagon are put, each pillar 4 is equipped with a metal bar 5 and hangs down with the pillar 4 where it
Directly, the position that two adjacent metal bars 5 are installed on pillar 4 is one high and one low；Groove is provided with the afterbody of metal bar 5, is set in groove
There is resetting spring 6, one end of resetting spring 6 is connected with metal bar 5, and the other end of resetting spring 6 is connected with pillar 4, Gu
Surely card 2 is located at same level with turntable 7, and fixing card 2 is used to fix turntable 7, in the other end (rear end) of pinch bar 1, mirror
As being provided with fixing card 2, ratchet shape groove 3, pillar 4, metal bar 5, resetting spring 6 and turntable 7.
The fixing card 2 is made of arc panel 2-1, straight panel 2-2 and knob 2-3, and arc panel 2-1 is fixed on straight panel 2-2's
Front end, knob 2-3 be arranged on the rear portion of straight panel 2-2 and with the threaded connection of straight panel 2-2.In use, when turntable 7 adjusts spanner mouth
Into to after appropriate size, reach fixing card 2 makes arc panel 2-1 withstand turntable 7, screws knob 2-3 and causes fixing card 2 and turntable 7
It is not rotated further by.
Spanner mouth is tuned into by appropriate size by the turntable 7 of 1 front end of rotary spanner handle, then by fixing card 2 by its
It is fixed together with pinch bar.Six roots of sensation pillar 4 is installed on turntable 7, one and its are separately installed with six roots of sensation pillar 4
Vertical metal bar 5,5 tail end of metal bar are contacted with the cell wall of the ratchet shape groove 3 on 1 head of pinch bar, so as to fulfill six roots of sensation gold
Belonging to the hexagon that rod 5 surrounds can zoom in or out with the rotation of turntable 7, to adapt to various sizes of nut or screw rod
Cap.Metal bar 5 is provided with groove in 4 installation place of pillar vertically, and resetting spring 6 is housed in groove.When spanner screws direction to nut
During rotation, ratchet applies effect of the torque so as to fulfill tightening nut to metal bar applying power, metal bar 5 to nut.Rotation one
It can not continue to rotate to operative orientation if determining handle after angle and running into barrier, at this time due to the characteristic of ratchet, the tail of metal bar 5
End can be streaked from ratchet cell wall, therefore only need to rotate along operative orientation again after rotating in the opposite direction handle to suitable position
It is not required to spanner be pulled down or adjusted size.Fixing card 2, the ratchet of the rear end mirror image of pinch bar 1 are then used during loosening nut
Shape groove 3, pillar 4, metal bar 5, resetting spring 6 and turntable 7.
The foregoing is only a preferred embodiment of the present invention, these embodiments are all based on the present invention
Different implementations under general idea, and protection scope of the present invention is not limited thereto, it is any to be familiar with the art
