The second engaging slot 163 that band 152 cooperates is played, the second pincers knife 16 is caught in the second groove 151 across protective case 3.
Through the above scheme, pincers knife engages across protective case 3 with clamp block, it is only necessary to cancel protective case 3, pincers knife can also take
Under, without disassembly, so that the replacement of pincers knife becomes simpler, convenient and quick.The cooperation of raised band and engaging slot and pincers
The groove of seat, which to clamp knife, to be engaged stronger, will not be fallen off easily, when replacement will not too bother.
First clamp block 12 is additionally provided with the first oblique arm 122 and the first hole 123, and the second clamp block 15 has been additionally provided with the second oblique arm 152
With the second hole 153, the other end of mounting base 2 is additionally provided with clamp block axis 22, and clamp block axis 22 passes through the first hole 123 and the second hole 153, makes
First clamp block 12 and the second clamp block 15 are rotatably connected on clamp block axis 22, and the first oblique arm 122 is hinged on the first connecting plate 11,
Second oblique arm 152 is hinged on the second connecting plate 14, and the other end of bracing wire 5 is equipped with connecting shaft 51, bracing wire 5 and the two of connecting shaft 51
End connection, the first connecting plate 11 are equipped with third hole 111, and the second connecting plate 14 is equipped with the 4th hole 141, and connecting shaft 51 passes through third hole
111 and the 4th hole 141, it is rotatably connected on the first connecting plate 11 and the second connecting plate 14 in connecting shaft 51.
Through the above scheme, cooperated by hole axle, the first clamp block 12 and the second clamp block 15 are rotatably connected on clamp block axis, just
In installation, be conducive to the completion of clamp movement.First oblique arm 122 and the second oblique arm 152 have the angle of rotation that do not interfere greatly more
Degree allows the angle between the first pincers knife 13 and the second pincers knife 16 bigger, possesses the range of bigger acquisition biopsy
The link mechanism formed with stronger bite force, the first clamp block 12, the second clamp block 15, the first connecting plate 11 and the second connecting plate 14
So that the displacement of bracing wire is converted into the rotation of the first clamp block 12 and the second clamp block 15, facilitates biopsy forceps and steadily clamp biopsy group
It knits.
One end of conduit 4 is equipped with external screw thread 41, and one end of mounting base 2 is equipped with threaded hole 21 compatible with external screw thread 41,
Mounting base 2 is threaded on conduit 4, and the position of the adjustable opposite conduit 4 of rotary mounting seat 2 controls connecting shaft 51 and pincers
The distance between seat axis 22, changes the angle between the first clamp block 12 and the second clamp block 15.
Through the above scheme, the shape for adjusting biopsy forceps increases a kind of opening biopsy forceps, takes out the side of biopsy
Method, it is not necessary to be pulled open with hand, or push-and-pull sliding sleeve 7.Connection installation convenient for assembly, it is easy to use, increase fine-tuning mode, improves biopsy
The serious forgiveness of pincers is unlikely to because bracing wire 5 loosens or deforming causes biopsy forceps to be scrapped.
Hand-held ring 8 is vesica piscis, and handle 6 is vertically fixed on the side of hand-held ring 8, and the centre of sliding sleeve 7, which is equipped with, is suitble to hand
Refer to that the annular groove 72 of clamping, sliding sleeve 7 are connected with embedded block 71, embedded block 71 passes through sliding slot 62 and connect with bracing wire 5, mounting base 2
Equipped with mounting groove 23, threaded hole 41 is arranged on the bottom surface of mounting groove 23, and clamp block axis 22 is arranged in mounting groove 23, the first groove
121 inner wall is equipped with the 5th hole 125 for ejecting the first pincers knife 13, and the inner wall of the second groove 151 is equipped with for ejecting
6th hole 155 of the second pincers knife 16.
Through the above scheme, holding ring 8 and sliding sleeve 7 can be used by the same hand, and thumb is inserted into hand-held ring 8, index finger and
Middle finger clamps sliding sleeve 7.It is easy to use, in addition a hand can carry out other necessary operations.
Protective case 3 is made of plastic film.
Through the above scheme, it is made using the plastic film of not cracky, so that the replacement of protective case 3 is simpler, is had
Conducive to the manufacturing, cost is reduced.
The above is only the preferred embodiment of the present invention, protection scope of the present invention is not limited merely to above-described embodiment,
All technical solutions belonged under thinking of the present invention all belong to the scope of protection of the present invention.It should be pointed out that for the art
For those of ordinary skill, several improvements and modifications without departing from the principles of the present invention, these improvements and modifications are also answered
