[0013] Figure 1 It is a partial front view of the utility model a kind of buffer type side bending bone holding forceps a preferred embodiment except retractor subassembly. DETAILED DESCRIPTION
[0014] The technical scheme in the embodiment of the utility model will be clearly and completely described as follows, and obviously, the described embodiment is only a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.
[0015] Please refer to Figure 1 The utility model embodiment includes:
[0016] A kind of buffer type side bending bone holding forceps, including jaw handle, cheek shaft screw 1, screw rod 2, nut 3, adjusting nut 4 and jaw.
[0017] Wherein, the jaw handle is provided with two including first jaw handle 5 and second jaw handle 6, the front part of the first jaw handle 5 and the second jaw handle 6 is fixedly connected by cheek shaft screw 1, so that the first jaw handle 5 and the second jaw handle 6 rotate around cheek shaft screw 1 use.
[0018] A screw rod 2 is hingedly provided on the inner side of the rear portion of the first clamp handle 5, and a positioning long hole 7 is provided on the rear portion of the second clamp handle 6. The screw rod 2 passes through the positioning long hole 7. The screw rod 2 is threadedly connected to an adjusting nut 4 on the inner side of the second clamp handle 6, and is threadedly connected to a nut 3 on the outer side. The positioning of the first clamp handle 5 and the second clamp handle 6 is achieved by adjusting the adjusting nut 4 and the nut 3.
[0019] The pliers head includes a first pliers head 8 and a second pliers head 9 , and the front ends of the first pliers handle 5 and the second pliers handle 6 are both provided with the first pliers head 8 and the second pliers head 9 via a buffer structure.
[0020] The buffer structure includes a first step 10 , a positioning column 11 , a second step 12 , a positioning nut 13 and a buffer spring 14 .
[0021] The first step 10 is fixed to the outer ends of the front of the first clamp handle 5 and the second clamp handle 6 respectively. The first clamp handle 5 is provided with a penetrating guide hole 15 for positioning and guiding.
