Description
Technical field
This utility model relates to a kind of endoscope-use sample pickup tongs.
Background technology
Disclosed a kind of endoscope sample pickup tongs Chinese patent ZL200720309034.4 number; Comprise that cup 1 ', two pliers cups 2 ', push-pull bar 3 ', two braces 4 ', bearing pin 5 ', spring hose 6 ' and steel cables 7 ' form; One end of push-pull bar 3 ' is connected with steel cable 7 ', and the other end and two braces 4 ' are hinged, and two braces 4 ' are hinged with two pliers cups 2 ' respectively; Two pliers cups 2 ' are hinged, as shown in Figure 1 through bearing pin 5 ' and cup 1 '.
The shortcoming of this endoscope sample pickup tongs is that two pliers cups are single handle structure, and the pliers cup is easy to cause binding clip mutual dislocation when closure of pliers cup front end when rotating each other, and closure is poor.
The utility model content
For overcoming the shortcoming of existing sample pickup tongs closure difference, this utility model provides a kind of pliers cup that can prevent rotating hour offset, avoids the endoscope-use sample pickup tongs of the closed dislocation of binding clip.
The endoscope-use sample pickup tongs comprises cup and a pair of pliers cup, and two pliers cups are hinged through bearing pin, and bearing pin is fixed on the cup, and the tail end of two pliers cups all extends back and forms the empennage of hook steel cable;
It is characterized in that: the empennage of the first pliers cup is provided with gathering sill, and the empennage of the second pliers cup is inserted and rotated in this gathering sill.
Further; The empennage of the first pliers cup comprises the first main wing plate and first side wing parallel with the first main wing plate that connects with steel cable; Between the first main wing plate and first side wing space is arranged, this space forms the empennage that allows the second pliers cup and is inserted and rotated the gathering sill in it.
Further, the empennage of the second pliers cup comprises the second main wing plate and second side wing parallel with the second main wing plate that connects with steel cable, between the second main wing plate and second side wing space is arranged;
Second side wing inserts between the first main wing plate and first side wing; Bearing pin passes the first main wing plate, second side wing, first side wing and the second main wing plate successively.
Further, the length of two side wings is all less than the length of the main wing plate of correspondence.
The technical conceive of this utility model is: through on the empennage of pliers cup, gathering sill being set; The empennage of another pliers cup is inserted in the gathering sill; Rely on the position-limiting action of gathering sill to stop skew each other between the pliers cup, reach the purpose of avoiding the closed dislocation of pliers cup.
The utlity model has and to prevent that the pliers cup from rotating hour offset, avoids the advantage of the closed dislocation of binding clip.

The specific embodiment
With reference to accompanying drawing 2-5, further specify this utility model:
The endoscope-use sample pickup tongs comprises that cup 1 and 21,22, two pliers cups of a pair of pliers cup 21,22 are hinged through bearing pin 3, and bearing pin 3 is fixed on the cup 1, and the tail end of two pliers cups 21,22 all extends back and forms the empennage of hook steel cable;
The empennage of the first pliers cup 21 is provided with gathering sill 2A, and the empennage of the second pliers cup 22 is inserted and rotated in this gathering sill 2A.
The empennage of the first pliers cup 21 comprises the first main wing plate 211 that connects with steel cable 4 and first side wing 212 parallel with the first main wing plate 211; Between the first main wing plate 211 and first side wing 212 space is arranged, this space forms the empennage that allows the second pliers cup 22 and is inserted and rotated the gathering sill 2A in it.
The empennage of the second pliers cup 22 comprises between the second main wing plate 221 that connects with steel cable 4 and second side wing, 222, the second main wing plates 221 parallel with the second main wing plate 221 and second side wing 222 has space 2B;
The length of two side wings 212,222 is all less than the length of the main wing plate 211,221 of correspondence.
The technical conceive of this utility model is: through on the empennage of pliers cup 21,22, gathering sill being set; The empennage of another pliers cup is inserted in the gathering sill; Rely on the position-limiting action of gathering sill to stop skew each other between the pliers cup, reach the purpose of avoiding the closed dislocation of pliers cup.
Specifically; Second side wing 222 of the second pliers cup 22 inserts between first side wing 211 and the first main wing plate 212 of the first pliers cup 21; The width in the space between first side wing 211 and the first main wing plate 212 and the width of second side wing 222 are adaptive, thereby second side wing 222 is limited between first side wing 211 and the first main wing plate 212.Simultaneously, also in the space between second side wing 222 and the second main wing plate 221, this space also is limited to first side wing 211 between second side wing 222 and the second main wing plate 221 first side wing 211.Therefore, when two pliers cups 21,22 rotated each other, empennage can only move between two planes, skew can not occur, had avoided the closure dislocation of pliers cup 21,22.
The utlity model has and to prevent that the pliers cup from rotating hour offset, avoids the advantage of the closed dislocation of binding clip.
The described content of this description embodiment only is enumerating the way of realization of utility model design; The protection domain of this utility model should not be regarded as and only limit to the concrete form that embodiment states, the protection domain of this utility model also reach in those skilled in the art according to this utility model design the equivalent technologies means that can expect.
