Abstract
The utility model discloses a kind of tarsus tweezer, including tweezer body and threaded post (2), one end of the threaded post (2) is connected with the screwed worm gear of endoporus (3), worm gear (3) is matched with worm screw (6), and worm screw (6) both ends are connected by stent (4) with tweezer body；There is an extension driving lever (5) in one end of the worm screw (6)；The worm gear (2) has a boss (7), boss (7) and tweezer body contact jaw rounded corner on the end face of tweezer body.The utility model changes the mode of operation during locking nut of existing tarsus tweezer, extension driving lever (5) need to be only stirred using thumb and completes locking operation, improve the convenience of operating personnel, reduce the frictional force of retaining mechanism and tweezer body and the dead weight of tweezer body at the same time, reach labour-saving purpose.
Description
Technical field
It the utility model is related to tarsus tweezer, the especially retaining mechanism on tarsus tweezer.
Background technology
One of common apparatus is tarsus tweezer in chalazion operation, its basic structure is as shown in Figure 1, two valve tweezer bodies it
Between be provided with a threaded post, threaded post one end is connected with a wherein valve tweezer body, the other end through another valve tweezer body and and nut
Coordinate, after the basic procedure of operation is local numb ferment, loosen the nut on tarsus tweezer, tumour is fixed on support tarsus and pressure eyelid ring
Between, then nut is tightened, realize and fix.Its advantage is that locking is firm to the tarsus tweezer of this structure when in use, but shortcoming is stubborn
The process of tight nut is cumbersome, it is necessary to two fingers pinch nut rotation, on the other hand, due to connecing for nut end face and tweezer body
Contacting surface (seal face) contacts for face, and frictional force is larger, and rundown process is harder.
The content of the invention
The technical problems to be solved in the utility model is：A kind of tarsus tweezer is provided, compared to existing nut check mechanism, is changed
Become mode of operation during locking nut, need to only be stirred using thumb and complete locking operation, improve the convenience of operating personnel, together
When reduce retaining mechanism and the frictional force of tweezer body and the dead weight of tweezer body.
To solve the above problems, the utility model adopts the following technical solution：
A kind of tarsus tweezer, including tweezer body and threaded post, it is characterised in that：One end of the threaded post is threaded with endoporus
Worm gear connection, worm gear matches with worm screw, and worm screw both ends are connected by stent with tweezer body；
There is an extension driving lever in one end of the worm screw；
The worm gear has a boss, boss and tweezer body contact jaw rounded corner on the end face of tweezer body.
There is annular knurl decorative pattern on the extension driving lever surface.
The length direction of the length direction and tweezer body of the extension driving lever has an acute angle.
The tweezer body is in fold-line-shaped.
The fold-line-shaped tweezer body includes two sections, and one section of thickness close to tweezer tail is more than one section of the thickness away from tweezer tail.
The utility model has the following advantages：
1. rotating extension driving lever by using thumb, the worm screw coaxial with extension driving lever is driven, so that drive worm gear to rotate, snail
Wheel passes through screw thread upper (lower) movement in threaded post in endoporus, so as to fulfill the locking and unlatching to tweezer body；
2. there is an acute angle in extension driving lever and tweezer body length direction, it is contemplated that angle during operation between thumb and palm
Degree, and extend the annular knurl on driving lever surface, then it is the frictional force improved between thumb and extension driving lever；
3. the tweezer body of two sections of broken-line types, reduces the opening range of tweezer body, the stroke of rotation extension driving lever is shortened, two sections
The different setting of tweezer body thickness, then be to mitigate the weight of whole tweezer body, torque reduced, so that laborsaving.
4. the boss of worm gear end face adds rounded corners with tweezer body contact position, the contact surface of end face and tweezer body is reduced
Product, reduces frictional force.
Brief description of the drawings
Fig. 1 is existing tarsus tweezer structure diagram；
Fig. 2 is the structure diagram of the utility model；
Fig. 3 is the close-up schematic view of worm gear in Fig. 2, worm screw and threaded post；
Fig. 4 is tweezer body and extends the angle schematic diagram between driving lever；
Fig. 5 is the boss and its chamfering schematic diagram of worm gear end face.
Embodiment
1~5 the utility model is described in further detail below in conjunction with the accompanying drawings：
Such as Fig. 2, a kind of tarsus tweezer, including tweezer body and threaded post 2, tweezer body are in fold-line-shaped, and fold-line-shaped tweezer body includes two sections, leans on
One section of thickness of nearly tweezer tail is more than one section of the thickness away from tweezer tail.One end of threaded post 2 worm gear 3 screwed with endoporus connects
Connect, worm gear 3 is matched with worm screw 6, and 6 both ends of worm screw are connected by stent 4 with tweezer body；There is an extension driving lever 5 in one end of worm screw 6, prolongs
Stretching 5 surface of driving lever has annular knurl decorative pattern.Such as Fig. 4, the length direction of the length direction and tweezer body that extend driving lever 5 has an acute angle；
Such as Fig. 5, worm gear 2 has a boss 7, boss 7 and tweezer body contact jaw rounded corner on the end face of tweezer body.
In use, stirring the surface of extension driving lever 5 by thumb, coaxial worm screw 6 is driven, so as to drive worm gear 3 to pass through
Screw thread upper (lower) movement in threaded post 2 on its endoporus, tweezer body is compressed by the end face of worm gear 3.
It is emphasized that this specific embodiment is only the explanation to the utility model, it is not new to this practicality
The limitation of type, the utility model are not limited to embodiment the embodiment described, every this area correlation technique person foundation
The various changes or deformation of the utility model also belong to this reality within the scope of the utility model claims and equivalent technology
With new protection domain.
