Runner 45 is arranged with the pincers pipe 2, the runner 45 covers whole connector, is provided with the runner 45 tight Determine screw 46, the holding screw 47 for contradicting pincers pipe 2 surface is provided with the tightening screw 46.

Pad 48 is provided with the pincers base 41, and pad 48 is between conflict ring 43 and adapter sleeve 40, it is described interior It is slidingly sealed on core bar 3 and is provided with seal cap 49, and seal cap 49 contacts at pincers base 41 close to one end end face of fixed clamp handle 6 On, and sealing pincers base 41 is compressed close to one end port of fixed clamp handle 6 by the seal cap 49 that compresses of a chain of rings.

By using above-mentioned technical proposal, during using Clip Applier, fixed clamp handle 6 is located at the palm of the hand of user Place, mobile clamp handle 7 are located at the finger of user, and by the grip at finger, and grip is relatively larger than the compression elasticity of spring 21 Afterwards so that direction movement of the mobile clamp handle 7 toward fixed clamp handle 6 so that forget the direction of clamp block 4 in the end of U-lag 19 in mobile clamp handle 7 It is mobile, and to drive push rod pin 18 to move so that push rod pin 18 drives push rod 10 close mobile toward the direction of clamp block 4, then Push rod 10 promotes connecting rod 11 to move, and internal core rod 3 is moved, and then promotes clamp block 4 to operate by internal core rod 3, and causes pincers The control clamping binding clip 5 of seat 4 carries out clipping operation, after the grip at the finger of user disappears, passes through the compression bullet of spring 21 Power causes spring 21 to promote fixed cover 20 so that fixed cover 20 moves toward the direction towards clamp handle 1, and fixed cover 20 drives inner core Bar 3 moves, and causes the homing of clamp block 4 so that clamping binding clip 5 opens, and after the homing of internal core rod 3, mobile clamp handle 7 is logical The thrust of spring 21 crossed at push rod 10 rotates on fixed handle, is moved toward the direction away from fixed clamp handle 6, and homing, So that convenient use person operates to Clip Applier.

So that, as axle center, mobile clamp handle 7 rotates in fixed clamp handle 6 at spindle screw 25, and by the setting of shaft screw, The assembly manipulation that can be moved easily between clamp handle 7 and fixed clamp handle 6, improve the production efficiency of product, and spindle screw 25 End face and fixed clamp handle 6 surface at grade so that avoid rat of the spindle screw 25 in fixed handle When there is spindle screw 25 and scrape the situation of personnel of damaging, and avoid spindle screw 25 in the surface indentation of fixed handle, There is foreign body retention and cause the inconvenient situation of operating equipment cleaning in recess.

In assembling process, flat recess 26 is manipulated by straight screwdriver, enabling calibration push rod 10 is being grasped Make the position of through hole 8, facilitate and calibrated between push rod groove 17 and groove 16, can be straight by the end of U-lag 19 on moving handle Connect and insert in push rod groove 17 and coordinate with push rod pin 18.

It is rotatably assorted between outer clamp block 27 and clamping binding clip 5 by the 3rd shaft hole 29 and roller pin 30 so that gripper clamp First 5 can clamp switching action in outer clamp block 27, and interior clamp block 28 and the operating side of clamping binding clip 5 coordinate so that interior clamp block 28 Operated, can be moved in outer clamp block 27 by the push-and-pull of internal core rod 3, and control the clamping and opening and closing of clamping binding clip 5.

Intersection between the skewed slot of left and right coordinates, and passes through the setting of slotted-guide pin 36 so that promotes slotted-guide pin in interior clamp block 28 During 36 movement, the crosspoint between the skewed slot of left and right is moved toward the direction away from clamp handle 1, and left binding clip 31 and right binding clip 32 are by turning Pivot pin 30 is rotatablely installed in outer clamp block 27 so that when slotted-guide pin 36 moves, the bare terminal end of left and right binding clip 32 is close to each other to be connect Touch, in 36 homing of slotted-guide pin, the crosspoint between the skewed slot of left and right is moved toward close to the direction of clamp handle 1, and causes left and right The bare terminal end of binding clip 32 is separated from each other.

Pass through the setting of steady pin 38 and fixing hole 37 so that fixed cover 20 is facilitated in internal core rod 3, and in length It can avoid separating between fixed cover 20 and internal core rod 3 during time use, cause bullet of the spring 21 to fixed cover 20 Power distress resolves so that Clip Applier can not normal use situation.

During using Clip Applier, due to the setting of tumbler 39 so that motionless by clamp handle 1, rotating pincers pipe 2 makes The synchronous axial system of binding clip 5 must be clamped, facilitate user needs to rotate the situation of the binding clip clamped during using Clip Applier, Avoiding the movement of the part of clamp handle 1 causes clamping binding clip 5 to rock the crisis situations for malpractice occur.

Pincers base 41 is fixedly connected with pincers pipe 2, and adapter sleeve 40 is fixedly connected with fixed clamp handle 6, clamps base 41 and adapter sleeve Connected between 40 by overcoat 42, and the setting by contradicting ring 43 He keeping out ring 44, enable to clamp base 41 and adapter sleeve Mutually rotate and do not separate between 40, be furthermore enable in the case where clamp handle 1 is motionless, the convenient pipe 2 that clamps rotates and synchronous The control clamping rotating operation of binding clip 5, passes through the setting of connected ball 12 and connecting rod 13 between connecting rod 11 and push rod 10 so that even Bar 11 is rotated in company with pincers pipe 2, and push rod 10 is not rotated, and the connection between connecting rod 11 and push rod 10 can be avoided to separate feelings Condition.

When setting runner 45 to avoid user's needs rotation pincers pipe 2 on pincers pipe 2, pincers pipe 2 is caused to rotate inconvenience Situation, and by the setting of runner 45, cover connector, avoid connector it is exposed caused by product appearance structure it is imperfect Situation, and foreign matter can be avoided to directly contact the situation that connector causes connector to occur damaging or pollute, additionally be able to Other staff cause situation about being separated between connector in the case where operating Clip Applier unavoidably.

By the setting of pad 48, adapter sleeve 40 can be avoided directly to contradict with contradicting the surface of ring 43, cause adapter sleeve 40 Surface abrasion of the end face with contradicting ring 43 situation, being capable of airtight connection set 40 and pincers base 41 by the setting of seal cap 49 Between gap, and the gap that seal cap 49 can be between closed internal core rod 3 and seal cap 49 so that cavity in pincers pipe 2 with Isolated between operation through hole 8 in clamp handle 1 by seal cap 49, avoid Clip Applier in use, pincers pipe 2 occurred and fall leaves The situation of gas leakage.

Described above is only preferred embodiment of the present utility model, and the scope of protection of the utility model is not limited merely to Above-described embodiment, all technical schemes belonged under the utility model thinking belong to the scope of protection of the utility model.It should refer to Go out, for those skilled in the art, some improvement under the premise of the utility model principle is not departed from and Retouching, these improvements and modifications also should be regarded as the scope of protection of the utility model.
