Specific embodiment

The utility model is further described with reference to the accompanying drawing.Following embodiment is only used for clearly illustrating this The technical solution of utility model, and cannot be used as a limitation the limitation protection scope of the utility model.

As shown in Figure 1, 2: a kind of medical bar bending pliers, including claw beam 1 and claw beam 24, one 1 one end of claw beam are equipped with first Hand-held part 11, the other end connect the first clamping part 2, and 24 one end of claw beam connects the second hand-held part 3, and the other end is equipped with the second clamping Portion 41, the end of the first clamping part 2 are equipped with the first clamping part protrusion 21, and the first clamping part protrusion 21 connects the second clamping part 41, Second hand-held part 3 is equipped with the second hand-held part protrusion 31, and the second hand-held part protrusion 31 connects claw beam 1, claw beam 1 and claw beam 24 It include bending section 5 and arc sections 6, the bending direction of bending section 5 is flat where the first hand-held part 11 and the second hand-held part 3 Face.

As shown in Figure 3: the raised interconnecting piece of above-mentioned two claw beam is equipped with pit, and protrusion is equipped with through-hole, is connected to by pin shaft Inside pit, (opposite sliding occurs between two claw beams) when through operation hand-held part open or close clamping part in this way, protrusion It is rotated centered on connecting pin shaft in pit, slightly larger than raised section, such protrusion can have enough in the section of pit Activity space.

In conjunction with Fig. 4 and Fig. 5: bending direction of the circular arc direction of arc sections 6 perpendicular to bending section 5.In this way, arc sections 6 Just there are two (two opposite), one is shown in Fig. 4 in circular arc direction, the other is shown in Fig. 5, in practical application, the two circle Arc direction can respectively do one, and partner tool.It should be noted that due to operating clamping part clamping by hand-held part or opening When opening, two claw beams slide axially, therefore in practical manufacturing process, because controlling the radian size of arc sections 6, avoid because of circle The excessive situation for causing clamping part that can not open of 6 radian of arc portion.

For the reliability of enhancing clamping part clamping, the first clamping part 2 is additionally provided with the first clamping part anti-slip layer 22, the second clamping Portion 41 is additionally provided with the second clamping part anti-slip layer 411, and the first clamping part anti-slip layer 22 is anti-skidding with the second clamping part anti-slip layer 411 Protrusion, the axis of the direction of anti-skid bulge perpendicular to place clamping part.It can prevent clipped object from disengaging in this way.

The first hand-held part extension 12, the first hand-held part extension are additionally provided in conjunction with the hand-held part of Fig. 1,2 and Fig. 7: the first 11 12 are equipped with ratchet 1, and the second hand-held part 3 is additionally provided with the second hand-held part extension 32, and the second hand-held part extension 32 is equipped with spine Tooth 2 321, when the first clamping part 2 engages with the second clamping part 41, ratchet 1 connect ratchet 2 321, ratchet 1 with One of them only has single tooth to ratchet 2 321, another has multiple teeth, is convenient for the clamping of two ratchets in this way, when needing to disengage two When ratchet, it is only necessary to go slightly with making every effort to defeat out two hand-held parts.

The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art For art personnel, without deviating from the technical principle of the utility model, several improvement and deformations can also be made, these change It also should be regarded as the protection scope of the utility model into deformation.
