One stent 3, is provided with first ball spout set along 3 length direction of first support on the madial wall of first support 3
4, adding the right end of block 1 to be hinged with second support 5, one is provided with the madial wall of second support 5 along 5 length of second support
The second ball spout 6 that direction is set, is respectively arranged with some installing draw point 7 in first support 3 and second support 5
Purl device 8, through block 1 is added, the other end of Lengthened bolt 2 is provided with conductor mount 9, is leading the threaded one end of the Lengthened bolt 2
The left end of body frame 9 is hinged with the first strut 10, and being respectively arranged with one in the outer end of the first strut 10 can be in first support 3
The first ball spout 4 in the ball that moves, the first strut 10 is by the way that ball is slidably disposed within the first spin sliding slot 4 and with
One stent, 3 phase is slidably connected, and is hinged with the second strut 11 in the right end of conductor mount 9, is set respectively in the outer end of the second strut 11
A ball 12 that can be moved in the second ball spout 6 in second support 5 is equipped with, the second strut 11 is by the way that ball 12 is slided
It is dynamic to be placed in the second spin sliding slot and be slidably connected with 5 phase of second support, when edge plus block 1 move forward after the rotation of Lengthened bolt 2, add
Stay bolt 2 can synchronous drive conductor mount 9 move forward, conductor mount 9 by the first strut 10 and the second strut 11 promote first support 3 and
Second support 5 is gradual outwards mutually to open, and when being moved after edge plus block 1 after the rotation of Lengthened bolt 2, Lengthened bolt 2 can synchronous drive
Moved after conductor mount 9, conductor mount 9 pulls first support 3 and second support 5 gradually inside by the first strut 10 and the second strut 11
Mutually collapse；In the present embodiment, due to purl device 8 and the connection structure all same of corresponding stent, below only with purl device 8 with
Illustrated exemplified by the connection structure of first support 3, purl device 8 and the connection mode of first support 3 are：Including clamping screw
13, the threaded hole screwed in for clamping screw 13 is provided with purl device 8, up/down perforation first is provided with first support
Frame and it is not connected and to place longitudinal bar shaped sliding slot 14 of purl device 8 with the first ball spout 4, in first support 3
It is provided with lateral wall and is connected and is not slided with the first spin the horizontal bar shaped cunning that 4 grooves are connected with longitudinal bar shaped sliding slot 14
Groove 15, will when purl device 8 is positioned over longitudinal bar shaped sliding slot 14 and the threaded hole of purl device 8 is directed at horizontal bar shaped sliding slot 15
Clamping screw 13 screws in the threaded hole of purl device 8 from horizontal bar shaped sliding slot 15, and the nut and purl device 8 that can make clamping screw 13 are in
Opposite clamping shape clamps first support 3, so as to purl device 8 is fastened in first support 3, the structure of above-mentioned connection structure
Simply, installation and adjustment locker is very convenient, greatly improves work efficiency；
The operation principle of the utility model is as follows：
Draw point 7 is first squeezed on thumb, then by purl device 8 and clamping screw 13 by the draw point 7 on thumb with
First support 3 is connected to a fixed, and then rotation adjusts Lengthened bolt 2, until Lengthened bolt 2 passes through conductor mount 9, the first strut
10 and second strut 11 coordinate second support 5 moved into forefinger position, be then also loaded onto purl device 8 and locking screw in second support 5
Bolt 13, then squeezes into forefinger proximal phalanx by the purl device 8 in second support 5 by another draw point 7, thus complete extension apparatus with
The fixation of thumb and forefinger, then rotates and adjusts Lengthened bolt 2, Lengthened bolt 2 is being lengthened along adding block 1 slowly to move forward again
During bolt 2 moves forward, the meeting synchronous drive of Lengthened bolt 2 conductor mount 9 moves forward, and conductor mount 9 passes through the first strut 10 when moving forward
With the second strut 11 first support 3 and second support 5 can be promoted gradually outwards mutually to open, thus by draw point 7 by forefinger and
Thumb slowly opens, and tiger's jaw is opened up into normal angled；When needing to collapse the tiger's jaw of opening, can reversely rotate
Lengthened bolt 2, makes Lengthened bolt 2 be moved along after adding block 1 slowly, and during being moved after Lengthened bolt 2, Lengthened bolt 2 can be synchronous
Moved after pulling conductor mount 9, first support 3 and second can be promoted by the first strut 10 and the second strut 11 when being moved after conductor mount 9
Stent 5 gradually inwardly mutually collapses, so as to slowly be collapsed forefinger and thumb by draw point, so as to complete the receipts to tiger's jaw
Hold together.The utility model has the advantages that：It is simple in structure, it is easy to use, can be to the thumb that cannot mutually be opened by lopsided adhesion
The damage with forefinger and caused by extraneous factor and can not normally the thumb metacarpal bone of opening and closing and the progress of forefinger metacarpal bone be effective slow
Drawing-off, drawing-off effect are good.
