Determine jaw to be fixed on bearing, connected between described two moving jaws and regular jaw by shaft, described two adjustable clamps
The end of mouth is connected by a connecting rod piece with a push-pull rod respectively, and the push-pull rod is connected with haulage cable, the connecting rod piece
It is to be rotatablely connected between push-pull rod and moving jaw, the haulage cable being connected with described two moving jaws is respectively positioned on one
In bourdon tube, the bourdon tube is fixedly connected with bearing.
Locking device being both provided with each handle propeller, being locked with will pass through after a moving jaw samples,
Then sampled again by another moving jaw.
The regular jaw be fixed on both sides be provided with the corresponding inner concave of both sides moving jaw, in the fixation
Bakie or leakage hole are additionally provided with jaw and the first sampling jaw and the second sampling jaw.
The double end scope of the present invention after once stretching into vivo, can pass through two handle propellers with hose type sample pickup tongs
Two moving jaws of control act respectively, while obtain two pieces of living tissue specimens, in same room and time, there is provided
Pathologic specimen is one times more, and verification and measurement ratio doubles, it is possible to reduce patient's pain and operating time, are lost endoscope equipment smaller.

Fig. 2 is the partial enlarged view at jaw position in Fig. 1.
Fig. 3 is another usage state diagram at jaw position.
Fig. 4 is the structure diagram of handle propeller locking device.
Embodiment
The invention will be further described with reference to the accompanying drawings and examples.
As shown in the figure, a kind of double end scope hose type sample pickup tongs, it is characterised in that the sample pickup tongs includes a fixation
Jaw 1, the regular jaw are fixed on mount 18, and the regular jaw both sides are respectively arranged with the first moving jaw 2 and the
Two moving jaws 3, the first moving jaw, the second moving jaw and regular jaw are connected by a shaft, the first moving jaw
Sample pickup tongs mouth in a pair is combined with the regular jaw, the second moving jaw also combines sample pickup tongs in a pair with the regular jaw
Mouthful, the end of the first moving jaw is connected by first connecting rod piece 4 with the first push-pull rod 5, and the first connecting rod piece 4 and first pushes away
It is rotation connection between 5 and first moving jaw 2 of pull rod, first push-pull rod 5 passes through the first haulage cable 6 and first
Handle propeller 7 connects, and the end of the second moving jaw is connected by second connecting rod piece with the second push-pull rod, the second connecting rod
It is rotation connection between piece and the second push-pull rod and the second moving jaw, second push-pull rod passes through the second haulage cable
8 are connected with second handle propeller 9, i.e., each handle propeller controls a moving jaw by a haulage cable respectively
Action.First haulage cable and the second haulage cable are respectively positioned in bourdon tube 10.
The sample pickup tongs as shown in Figure 4 further includes one handle mobile jib 11, and handle mobile jib 11 and one end of bourdon tube 10 are fixed
Connection, the other end of bourdon tube 10 are then fixedly connected with stent 18, and the handle propeller 13 is arranged on the two of handle mobile jib 11
Side, be provided with handle propeller 13 with the matched mobile jib sliding slot 12 of handle mobile jib, can slide along handle mobile jib, be pushed away in handle
A limited block sliding slot 14 is additionally provided with into device 13, the limited block sliding slot 14 is vertically arranged with mobile jib sliding slot 12, and limited block is slided
A spring 15 is provided with groove, a limited block 16 is provided with the inside of spring, is provided with handle mobile jib and the limited block phase
The limiting slot 19 of cooperation, when handle propeller is slided along handle mobile jib, spring keeps confined state, when handle propeller
When limited block is moved to the limiting slot of handle mobile jib, under the action of spring-return power, limited block enters in limiting slot, and handle pushes away
It is locked into device, while the position of moving jaw is also locked.A driving lever 17 is additionally provided with the limited block, when needing to unlock
When, stir driving lever so that limited block is retracted into limiting slot, then handle pusher is unlocked.
In use, promoting first handle propeller 7 forward, the first push-pull rod 5 is driven forward by the first haulage cable 6
