Description

Technical Field

[0001] The utility model relates to the field of surgical instruments, in particular to a pair of reaction forceps. Background Art

[0002] Tweezers, also known as pliers, are frequently used in daily use and medical treatment. Conventional pliers close when pressed by hand and open when no pressure is applied, while reaction force pliers are used differently, opening when pressed by hand and closing when no pressure is applied. However, current reaction force pliers do not have an adjustable locking function, and the pliers need to be pressed continuously to keep them open, which is not convenient to operate.

[0003] Therefore, in order to solve the deficiencies in the prior art, a reaction force pliers with a simple structure needs to be designed. Utility Model Content

[0004] The utility model provides a reaction force type pliers to solve the problems of the prior art.

[0005] The purpose of the utility model can be achieved through the following technical solutions: a reaction force pliers comprises: a female piece, a male piece and a locking device, the female piece and the male piece are arranged alternately and the right end of the female piece is fixedly connected to the right end of the male piece, the upper end of the female piece is provided with a clamping hole, the locking device comprises a fixed block and a lock buckle, the fixed block is arranged on the upper end surface of the middle part of the male piece, the lock buckle is arranged on the left side of the fixed block, the upper end of the lock buckle is provided with a multi-stage ratchet, and the multi-stage ratchet is clamped in the clamping hole.

[0006] As a further improvement, the left ends of the female piece and the male piece both include a clamping portion, an elbow is provided at the end of the clamping portion, a clamping groove is provided on the inner side of the elbow, and anti-slip teeth are provided on the outer side of the elbow.

[0007] As a further improvement, slots are provided between the multi-stage ratchet teeth, and the right side of the multi-stage ratchet tooth cross section is an arc-shaped cross section.

[0008] As a further improvement, the fixing block is fixedly connected to the upper end surface of the middle part of the male piece by means of screws.

[0009] As a further improvement, the outer end surfaces of the middle parts of the female piece and the male piece are both provided with anti-slip parts.

[0010] Compared with the prior art, the reaction force pliers of the utility model have the following beneficial effects:

[0011] Press the female and male pieces to open the instrument head for clamping parts. If a large opening degree needs to be maintained, the locking device fixed by the male piece is used to fix the lower section of the multi-stage ratchet teeth of the lock buckle in the position of the clamping hole of the female piece, thereby stopping the female and male pieces and preventing them from rebounding and closing. If the clamping state needs to be restored, the lock buckle is pulled to disengage the lower section of the multi-stage ratchet teeth from the position of the clamping hole, so that the female and male pieces rebound to the required position. After returning to this state during use, the adjustment is convenient and efficient. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0016] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0017] The following is combined with the embodiments and attached Figures 1-2 , the technical solution of the utility model is further elaborated.

[0018] Example 1

[0019] A reaction force pliers, comprising: a female piece 1, a male piece 2 and a locking device 3, wherein the female piece 1 and the male piece 2 are alternately arranged and the right end of the female piece 1 is fixedly connected to the right end of the male piece 2, the upper end of the female piece 1 is provided with a clamping hole 11, the locking device 3 comprises a fixing block 31 and a lock buckle 32, the fixing block 31 is arranged on the upper end surface of the middle part of the male piece 2, the lock buckle 32 is arranged on the left side of the fixing block 31, and the upper end of the lock buckle 32 is provided with a multi-stage ratchet 33, and the multi-stage ratchet 33 is clamped in the clamping hole 11.
