It is dynamic.Specifically, clamping piece 20 is in close state before using syringe 200, when in use, rotated by control handle 30
Torsion bar 41 drives driving gear 42 to rotate.Driving gear 42 drives the rotation of the first driven gear 43, and the first driven gear 43 drives
The rotation of second driven gear 44, thus, two clamping pieces 20 opposite simultaneously can be opened.It should be understood that gear drive herein
Mode be only a preferred embodiment of the present invention, can also be arranged two driven gears simultaneously and driving gear 42 it is ratcheting, lead
Moving gear 42 rotates, while driving the rotation of two driven gears, so that two clamping pieces 20 are opened.
It is rotated it should be understood that driving member 40 may also be configured to torsion bar 41 with moving gear, is then driven and pressed from both sides by gear
Gripping member 20.It may be set to be the disc type connector of rotation, clamping piece 20 hingedly then driven by toothed disc, in the present invention
Protection scope in.
With further reference to Fig. 2,3, the fixed part 222 is substantially cylindrical, and the corresponding fixed part 222 of shell 10 is equipped with circle
The via hole 10b of shape, fixed part 222 pass through via hole and connect with driving member 40, and clamping piece 20 can be around the circumferential direction of the fixed part 222
Rotation.That is, fixed part 222 can be driven to rotate when driving member 40 rotates, so that clamping piece 20 can be rotated to be formed and be beaten
Open and close two states.
Referring once again to Fig. 1, flexible reset spring 223 is arranged on each fixed part 222, the flexible reset spring
223 between driven gear and the inner wall of front housing 11.In this way, boss 111 is by sliding groove 221 when clamping piece 20 rotates
Depths to shallow place, flexible reset spring 223 are in tensional state.When boss 111 slides from shallow to deep, stretch reset spring
223 are in elastic reset state, and it is close to shell 10 that flexible reset spring 223 facilitates clamping piece 20, belong to boosting mechanism.
Fig. 1, Fig. 4 and Fig. 5 are please referred to, the control handle 30 includes squeezing handle 31 and the second sleeve set on 31 one end of squeezing handle
32, shell 10 includes front housing 11 and rear shell 12, and the corresponding second sleeve 32 of the rear shell 12 is equipped with circular relief hole 121, and second set
Cylinder 32 passes through relief hole 12 and connect with torsion bar 41, and squeezing handle 31 can be rotated around second sleeve 32.In this way, being opened in control clamping piece 20
When opening, squeezing handle 31 can be rotated, torsion bar 41 is driven to rotate, it is convenient and efficient.
Further, second sleeve 32, which is also arranged with, resets ring 33, resets ring 33 and passes through the first elastic component 34 and rear shell
12 inner wall connection.First elastic component 34 is used to the squeezing handle 31 in open configuration returning back to reset state.By resetting ring
33 setting facilitates and resets squeezing handle 31.Certainly, spring can be used in the first elastic component 34, can also use flexible skin
Muscle or other elastic components, are within the scope of the invention.
Preferably, the installation of ring 33 is resetted for convenience, the present invention is using following setting: referring to Fig.1, resetting ring 33 and be equipped with
