Accompanying drawing explanation
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further:
Fig. 1 is the structural representation of this utility model surgical knife.
Detailed description of the invention
As shown in Figure 1, this utility model surgical knife comprise blade 1, the support bar 5 be fixedly connected with blade 1, the handle of a knife 4 be connected with support bar 5 and be coated on the shell 2 of handle of a knife 4 periphery.
As shown in Figure 1, described support bar 5 is in cuboid, and its one end is fixedly connected with described blade 1, and the other end turns with described handle of a knife 4 axle and is connected.The right surface of described support bar 5 is provided with crook 7, and the left side of described crook 7 is cuboid, and its left end is fixedly connected with the right surface of described support bar 5, and the other end is hook-shaped.Described handle of a knife 4 is provided with fixed axis 6, and described fixed axis 6 is provided with torsion spring, makes fixed axis 6 have the tendency rotated counterclockwise, and described fixed axis 6 turns with its axle through described support bar 5 and is connected.Described shell 2, in cuboid, is provided with the cavity of the described handle of a knife 4 of a collecting in it.The left surface of described shell 2 is provided with the first catch 8, thus prevents described handle of a knife 4 from departing from described shell 2.Described handle of a knife 4 is provided with a roller 9, thus facilitates described handle of a knife 4 to move left and right.The rear surface of described handle of a knife is provided with cross bar 10 and first spring 11, and described cross bar 10 is slidably connected with described surgery through the right surface of described shell 2, and the right surface of described cross bar 10 is provided with the first pressing plate 12, and person easy to use presses.One end of described first spring 11 is fixedly connected with the right surface of described handle of a knife 4, and the other end is fixedly connected with described shell 2, thus makes described handle of a knife 4 have the tendency moved right.The below of described handle of a knife 4 is provided with the second catch 13, and described second catch 13 is fixedly connected with described shell 2 and is positioned at the rear of described handle of a knife 4, thus stops that described handle of a knife 4 moves right.Described second catch 13 tilts to the right.The below being positioned at described handle of a knife 4 is provided with a rectangular block 15, the connecting rod 17 be fixedly connected with rectangular block 15, the second pressing plate 14 and the second spring 16 of being fixedly connected with connecting rod 17.Described rectangular block 15 is in cuboid, and described connecting rod 16 can be cuboid, also can be cylinder, and described second pressing plate 14 is cylinder.The upper end of described second spring 16 is fixedly connected with the lower surface of described rectangular block 15, and lower end is fixedly connected with the lower surface of shell 2, and described connecting rod 17 is through the lower surface of described shell 2.Described second spring 16 makes described rectangular block 15 have the tendency moved down.
As shown in Figure 1, described this utility model also comprises a blade shell 3, and the cuboid of described blade shell 3 in vertical shape, the lower end on its right surface is fixedly connected with the upper end of the left surface of described shell 2.Described blade shell 3 can the left part of coated described blade 1 and support bar 5.
As shown in Figure 1, after described this utility model surgical knife is finished using, only need upwards to press the second pressing plate 14, under the effect of connecting rod 17, described handle of a knife 4 is moved up, now the second catch 13 no longer leans the rear surface of described handle of a knife 4, thus handle of a knife 4 moves right under the pulling function of the first spring 11; Then crook 7 is when touching the left surface of described shell 2, and due to the effect on the arc-shaped surface of crook 7, described blade 1, support bar 5 and crook 7 start to rotate clockwise around described fixed axis 6.When described handle of a knife 4 moves to Far Left, now blade 1 is contained in blade shell 3 completely, thus can play a protective role to blade 1, prevents it from hurting others.When needs use scalpel, only need pressing first pressing plate 12, until make the second catch 13 rely on the right surface of described handle of a knife 4, the now effect of the torsion spring of support bar on fixed axis 6 rotates counterclockwise, until support bar 5, blade 1, handle of a knife 4 are in a straight line.
