It is carried out below with reference to technical effect of the embodiment and attached drawing to the design of the utility model, specific structure and generation
It clearly and completely describes, to be completely understood by the purpose of this utility model, feature and effect.Obviously, described embodiment
It is a part of the embodiment of the utility model, rather than whole embodiments, it is based on the embodiments of the present invention, the skill of this field
Art personnel other embodiments obtained without creative efforts belong to the model of the utility model protection
It encloses.In addition, all connection/connection relationships being previously mentioned in text, not singly refer to that component directly connects, and referring to can be according to specific reality
Situation is applied, by adding or reducing couple auxiliary, Lai Zucheng more preferably coupling structure.Each technology in the utility model is special
Sign, can be with combination of interactions under the premise of not conflicting conflict.
Referring to figs. 1 to Fig. 3, this is the embodiment of the utility model artificial auditory ossicle mounting clamp, specifically:
A kind of artificial auditory ossicle mounting clamp, including clamp handle 1, vice body 2, clamp handle 1 is whole to be extended longitudinally, and vice body 2 is whole along cross
To extension；Clamp handle 1 includes left handle 11, right handles 12, and left handle 11 is connected with right handles 12 with shaft；Vice body 2 includes being all provided with
There are upper clamp 21, the lower clamp 22 at both ends, lower clamp 22 is equipped with guide rail, and guide rail extends transversely, and upper clamp 21, which is connected to, leads
On rail；The right end of lower clamp 22 is fixedly connected with the upper end of right handles 12；The upper end of left handle 11 is equipped with sliding slot 111, sliding slot 111
It is tilted towards right side；21 right end of upper clamp is equipped with the connecting shaft 211 of through-thickness, and connecting shaft 211 is located in sliding slot 111；Upper pincers
The left end of body 21 is equipped with the first clamping part 212, and the left end of lower clamp 22 is equipped with the second clamping part 222, the first clamping part 212 and the
The of laterally opposite face of two clamping part 222 is parallel to each other.The shape of a bending is integrally formed in clamp handle 1 and vice body 2, when left handle 11
When opening with right handles 12, sliding slot 111 is driven to rotate；Since sliding slot 111 is inclined towards right side, therefore sliding slot 111 drives connection
Axis 211 moves to the right, so that upper clamp 21 moves to the right along the guide rail of lower clamp 22, the second clamping part 222 is moved right,
And then realize the opening of the first clamping part 212 and the second clamping part 222, rather than opened to two sides.Due to the first clamping part 212
It is with the of laterally opposite interview of the second clamping part 222 parallel to each other, therefore any position is equidistant between of laterally opposite face.
It is further used as preferred embodiment, further includes ratchet bar 3, pawl 4；The right end and right handles 12 of ratchet bar 3
It is fixedly connected, pawl 4 is connected with left handle 11 with shaft, and ratchet bar 3 and pawl 4 are fastened and connected, and the back of tooth direction of ratchet bar 3 is left
Handle 11；Pawl 4 is equipped with extension 41 far from one end of ratchet bar 3, and extension 41 stretches out the side of left handle 11.Operator exists
Using artificial auditory ossicle mounting clamp come when clamping artificial auditory ossicle, in order to keep clamping, hand needs persistently to have an effect, it is easy because of hand
It is tired or be accidentally unlocked and lead to that artificial auditory ossicle is not clamping and falls.In the present embodiment, operator first presses extension 41,
Open left handle 11 and right handles 12；When being closed left handle 11 and right handles 12, extension 41 is unclamped, then pawl 4 is certainly
It is again lower to compress ratchet bar 3 and realize fastening.Since the back of tooth of ratchet bar 3 is towards left handle 11, so when left handle 11 can lean on
Nearly right handles 12 and cannot far from right handles 12, thus realize the first clamping part 212 and the second clamping part 222 can clamp without
It can unclamp.When needing to unclamp the first clamping part 212 and the second clamping part 222, extension 41 is pressed again, opens left handle 11
With right handles 12.
It is further used as preferred embodiment, ratchet bar 3 is arc-shaped.Ratchet bar 3 is arc-shaped, so that the swing of pawl 4
Amplitude is more steady.
It is further used as preferred embodiment, further includes the elastic component 5 equipped with both ends, one end of elastic component 5 and left hand
Handle 11 connects, and the other end and the pawl 4 of elastic component 5 offset, center of rotation of the position that elastic component 5 and pawl 4 offset in pawl 4
Between the right end of pawl 4.Pawl 4 is pressed to ratchet bar 3 by elastic component 5, keeps the fastening of pawl 4 and ratchet bar 3 more stable.
It is further used as preferred embodiment, the elastic component 5 is spring or elastic pressuring plate.Spring or elastic pressuring plate knot
Structure is simple, and manufacturing cost is low, and the manufacturing cost of artificial auditory ossicle mounting clamp can be effectively reduced.
