Brief description of the drawings
Fig. 1 is the structure diagram of phalanges extension apparatus described in the utility model.
Embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1, the phalanges extension apparatus, including by the hinged head rod 2 of the first axis pin 1 with
Second connecting rod 3, slides on head rod 2 and is provided with one to install the first of draw point the folder pin sliding block 4, in the first folder
The retaining mechanism that the first folder pin sliding block 4 can be locked on head rod 2 is provided with pin sliding block 4, in the second connection
Slided on bar 3 and be provided with one to install the second of draw point the folder pin sliding block 5, being provided with the second folder pin sliding block 5 can be by the
The retaining mechanism that two folder pin sliding blocks 5 are locked in the second connecting rod 3, the outer end of the head rod 2 passes through second
Axis pin 6 is hinged with contiguous block 7, is fixed with fixing axle 8 in the outer end of the second connecting rod 3, passes through the 3rd axis pin in fixing axle 8
9 are hinged with connecting shaft 10, be arranged with connecting shaft 10 can axial rotation adjusting knob 11, in adjusting knob 11 and contiguous block
Adjusting screw rod 12 is provided between 7, one end of adjusting screw rod 12 is connected with contiguous block 7, the other end of adjusting screw rod 12 and adjusting
11 coaxial threaded of knob connects；In the present embodiment, due to being locked to press from both sides pin sliding block 4 by first in head rod 2
On retaining mechanism and the retaining mechanism being locked the second folder pin sliding block 5 in the second connecting rod 3 structure it is homogeneous
Together, only carried out below by being locked the first folder pin sliding block 4 exemplified by the structure of the retaining mechanism on head rod 2
Illustrate, the structure of the retaining mechanism is：The top of first folder pin sliding block 4 is provided with up/down perforation first and presss from both sides pin sliding block 4
Threaded hole, screw thread is provided with lock-screw 13 in threaded hole, and when being screwed down lock-screw 13, lock-screw 13 can be held out against
Head rod 2, so that the first folder pin sliding block 4 is fixed with 2 phase of head rod, above-mentioned locking mechanism structure is simple, peace
Fill easy to adjust；In the present embodiment, adjusting screw rod 2 is threadedly coupled with contiguous block 7, and so installation is more convenient；
During installation, draw point first is respectively penetrated on two phalanges of finger joint style for needing to adjust flexing position, is then adjusted
Rotation of adjustment knob 11, makes head rod 2 consistent with the lopsided angle of two phalanges with the angulation angle of the second connecting rod 3,
Then the first folder pin sliding block 4 is moved, until the first folder pin sliding block 4 is moved to installation corresponding with the draw point wherein on a phalanges
Behind position, then the lock-screw 13 on the first folder pin sliding block 4 is screwed, the first folder pin sliding block 4 is fixed with 2 phase of head rod；
