101, the other hand is held reset lever 103 and is moved along the axis of the second connecting tube 102 toward outside (on the left of paper), to overcome spring
110 elastic force makes jacking block 104 be detached from card slot 105.With reference to Fig. 2 B, 111 deformation of spring compression, jacking block 104 completely disengages card slot
105, stop mobile reset lever 103, articulating joints 106 enter rotary state by locked state.It is readily comprehensible, turn at this time
Dynamic first connecting tube 101, opposite second connecting tube, 102 bending of 101 energy of the first connecting tube, disk 107 can turn in engaging portion 108
It is dynamic.Bending angle is set when reaching, articulating joints 106 are again introduced into locked state by rotary state, with reference to Fig. 2 C, when another phase
Adjacent card slot 105 gradually goes to 104 position of jacking block, discharges reset lever 103, the elastic force of spring 110 is relied on, again by jacking block
In 104 push-in card slots 105, cooperates with card slot 105 and lock, so that disk 107 is relatively fixed again in engaging portion 108,
To fix the bending angle between the first connecting tube 101 and the second connecting tube 102.It such as needs to continue bending, then it can be again
Reset lever 103 is moved to overcome the elastic force of spring 111, can continue to adjust the first connecting tube 101 and second by this method
Bending angle between connecting tube 102.
With reference to Fig. 2A, 5 card slots 105 are provided in the periphery side of disk 107.It is equivalent to half of circumference 180 degree point
It is 4 parts, forms 45 degree of bending angle between two adjacent card slots 105.By taking Fig. 2A and Fig. 2 C as an example, 101 phase of the first connecting tube
To 45 degree of 102 downward bending of the second connecting tube.It is readily comprehensible, more card slots 105 can be opened up on disk 107, made
Opposite second connecting tube 102 of first connecting tube 101 can form more selectable bending angle.
Fig. 3 A show one embodiment of the utility model can bending connecting tube ginglymus under locked state
Structural schematic diagram.Fig. 3 B show one embodiment of the utility model can bending connecting tube after bending, hinge close
Save the structural schematic diagram under locked state.As shown, being provided with 3 card slots 105,105 ' in the periphery side of disk 107.
Wherein, card slot 105 is small than the width of its two adjacent card slot 105 ', and such card slot 105 ' is given to jacking block 104 1 slightly
It roomy space, can be appropriate although disk 107 is fixed in engaging portion 108 when jacking block 104 protrudes into card slot 105 '
It is movable in a lesser angle.Be described in detail in conjunction with Fig. 1 it is a kind of can bending connecting tube 100 operating process.With reference to figure
3A, can bending connecting tube 100 be under straight tube state, i.e., the first connecting tube 101 is aligned with the second connecting tube 102, between each other
Without bending angle.At this point, articulating joints 106 are in locked state, jacking block 104 is under the elastic force effect of spring 111, jacking block 104
In the card slot 105 that through-hole 109 in the second connecting tube 102 is inserted into disk 107, jacking block 104 and 105 close-fitting of card slot make
Disk 107 is relatively fixed in engaging portion 108.When can bending connecting tube 100 need bending when, user can hold on the other hand
One connecting tube 101, the other hand are held reset lever 103 and are moved along the axis of the second connecting tube 102 toward outside (on the left of paper),
To overcome the elastic force of spring 110, jacking block 104 is made to be detached from card slot 105.When jacking block 104 completely disengages card slot 105, stopping is mobile multiple
Position pull rod 103, articulating joints 106 enter rotary state by locked state.It is readily comprehensible, the first connecting tube is rotated at this time
101, opposite second connecting tube, 102 bending of 101 energy of the first connecting tube, disk 107 can rotate in engaging portion 108.Scheme when reaching
After the bending angle of 3B setting, articulating joints 106 are again introduced into locked state by rotary state, discharge reset lever 103, rely on
Jacking block 104 is pushed into card slot 105 ' by the elastic force of spring 110.Due to card slot 105 ' be given to jacking block 104 1 it is slightly roomy
It space can be movable suitably in a lesser angle although disk 107 is fixed in engaging portion 108.In other words,
Bending angle between first connecting tube 101 and the second connecting tube 102 is fixed on an a small range, such as 45~60 degree,
To facilitate cleaning operation.
One kind provided by the utility model can bending connecting tube 100 by its articulating joints 106, make can bending connecting tube 100
It can be fixed on a bending angle, integrated operation is convenient and using effect is good.
