The second cross bar portion 23 of upper clamp 2 comprises the second main body 23-1 of cross bar portion, also comprises being successively set on the second main body 23-1 of cross bar portion bottom left gathering sill 23-2, guide pad insertion groove 23-3 and the right gathering sill 23-4 that Open Side Down from left to right.The second main body 23-1 of cross bar portion is horizontally disposed with, and left gathering sill 23-2 is identical with the cross sectional shape of right gathering sill 23-4, and basic configuration is the T type.23-3 is rectangular for the guide pad insertion groove, and its A/F is greater than the A/F of left gathering sill 23-2.
The connection chamber 24-1 of the connection cover portion 24 of upper clamp 2 is the arc connection chamber that Open Side Down.
Connecting pin 41 front and back of articulated elements are to being horizontally disposed with, and its two ends are fixedly linked with the inwall that is connected cover portion 24 respectively, and are positioned at the central position that connects cover portion 24.
See Fig. 8 and Fig. 9, adjustable clamp handle 3 is the steel integral piece, comprises the pincers handle main body 31 and the insertion rod portion 32 that link together; Insertion rod portion 32 comprises that the opening inserting groove 32-1 that makes progress and the front and back that are positioned at body of rod bottom that are positioned at body of rod top are to the through hole 32-2 that is provided with.The pincers handle main body thickness (also being sagittal distance) with connecting portion place insertion rod portion 32 31 are greater than the thickness of insertion rod portion 32, thus both connecting portion form be positioned at insertion rod portion 32 front and back stop step 33.Stop that step 33 is circular arc, be positioned at the top of pincers handle main body 31.The lower end of adjustable clamp handle 3 has 1 connecting hole 34 towards the right side.
See Fig. 3 to Fig. 9, lower clamp 1 is plugged on by 2 guide pads of its first cross bar portion 13 guide pad insertion groove 23-3 by upper clamp 2 in the corresponding gathering sill in 2 gathering sills of upper clamp 2, also be that left guide pad 13-2 is arranged in left gathering sill 23-2, right guide pad 13-3 is arranged in right gathering sill 23-4 (see figure 10), is connected thereby make upper clamp 2 horizontally slip with lower clamp 1.
The swing chamber 14-3 of lower clamp 1 is passed in the upper end of the insertion rod portion 32 of adjustable clamp handle 3, stretch in the connection chamber 24-1 of connection cover portion 24 of upper clamp 2, connecting pin 41 is connected among the inserting groove 32-1 of insertion rod portion 32 of adjustable clamp handle 3, makes the upper end of adjustable clamp handle 3 be dynamically connected with the cover portion 24 that is connected of upper clamp 2.The step 33 that stops of adjustable clamp handle 3 contacts with the arc-shaped convex 14-4 of the rotating junction 14 of lower clamp 1.
The screw 42 of articulated elements passes the through hole 32-2 of the insertion rod portion 32 of the fixing hole 14-5 of rotating junction 14 of lower clamp 1 and adjustable clamp handle 3 from front to back successively, screw in the fixing hole 14-5 of the rotating junction 14 of lower clamp 1, make the middle part of adjustable clamp handle 3 and the rotating junction 14 of lower clamp 1 be rotationally connected by screw 42, also be that adjustable clamp handle 3 can be that rotate with respect to lower clamp 1 at the center with screw 42, in rotation, the insertion rod portion 32 of adjustable clamp handle 3 can make upper clamp 2 horizontally slip with respect to lower clamp 1 by promoting connecting pin 41.The left nip part 11 of lower clamp 1 has formed the jaw that the rifle formula clamps jointly with the right nip part 21 of upper clamp 2, and the pincers shank 15 and the adjustable clamp handle 3 of lower clamp 1 formed the pincers shank of rifle formula pincers jointly.
See Figure 11 to Figure 14, the left shell fragment 5 of elastic supporting member for supporting optical member and right shell fragment 6 respectively are 1 steel bar.The upper end of left side shell fragment 5 is clamping 51, and the lower end has circular hole 52.The upper end of right shell fragment 6 is provided with clamping mouth 61, and lower end is hook-shaped fixing head 62, and right shell fragment 6 also has the circular hole 63 that is positioned at fixing head 62 tops.
The clamping 51 of left side shell fragment 5 is in the clamping mouth 61 of right shell fragment 6 by its cervical region, and both are dynamically connected.The circular hole 52 that left side shell fragment screw 7 passes on the left shell fragment 5 screws in the connecting hole 34 of adjustable clamp handle 3 lower ends, thereby makes the lower end of left shell fragment 5 be fixed on the right side of adjustable clamp handle 13.The fixing head 62 of right shell fragment 6 is inserted the connecting hole 15-1 that is arranged in the below of pincers shank 15 lower ends of lower clamp 1.The circular hole 63 that right shell fragment screw 8 passes on the right shell fragment 6 screws in the connecting hole 15-1 of the pincers shank 15 of lower clamp 1, thereby makes right shell fragment 6 be fixed on the left side of the pincers shank 14 of lower clamp 1.
At the pincers shank 15 of holding lower clamp 1 and adjustable clamp handle 3 and when making that upper clamp 2 slides with respect to lower clamp 1 left, because of the distance between the middle and lower part of left shell fragment 5 and right shell fragment 6 diminishes, then in left shell fragment 5 and 6 distortion of right shell fragment, produced elasticity, and made upper clamp 2 remain the trend of sliding to the right.When upper clamp 2 slides into the second brace portion 22 of the right side of the first brace portion 12 of lower clamp 1 and upper clamp 2 left with respect to lower clamp 1 left side is in contact with one another, then can not continue to slide left, this moment adjustable clamp handle 3 left surface also with the Zuo Bi joint, swing chamber of lower clamp 1.And under the situation that upper clamp 2 slides to the right with respect to lower clamp 1, when contacting with the swing chamber You Bi of lower clamp 1 on the right side that moves to adjustable clamp handle 3, can't continue to slide to the right.
The special-purpose rifle formula of the rib blade plate of present embodiment clamps in use, and one hand is held the pincers shank, makes jaw down.When rifle formula pincers are stretched into operative site from the right side by under the scapula, the rib blade plate 100 (Figure 15 and Figure 16) that at first makes jaw stride across rib and be positioned at fracture of rib line top, the lateral surface of the fixed claw 102-1 that is positioned at the left side on the left jaw bite 11-1 of the left nip part 11 of lower clamp 1 and the rib blade plate 100 in certain a pair of fixed claw 102 offsets, this fixed claw 102-1 embeds among the locating slot 11-2 of left nip part 11, and the first brace portion 12 of lower clamp 1 props up the plate body 101 of rib blade plate 100 from top to bottom.The lateral surface of the fixed claw 102-2 that is positioned at the right side on the right jaw bite 21-1 of the right nip part 21 of upper clamp 2 and the rib blade plate 100 in this a pair of fixed claw 102 offsets, this fixed claw 102-2 embeds among the locating slot 21-2 of right nip part 21, and the second brace portion 22 of upper clamp 2 props up the plate body of rib blade plate 100 from top to bottom.Then, pressurization on hand makes the upper clamp 2 of rifle formula pincers slide with respect to lower clamp 1 left, and right jaw bite 21-1 jaw bite 11-1 left draws close, this moment, above-mentioned a pair of fixed claw 102 also closed up to the centre under the effect of rifle formula pincers, held rib tightly thereby hold.When the second brace portion 22 of upper clamp 2 contacts with the first brace portion 12 of lower clamp 1, stop pressurization, loosen gradually then, in the process of loosening, under the elastic force effect of left shell fragment 5 and right shell fragment 6, jaw opens, and stops automatically after opening up into certain distance.The jaw of rifle formula pincers is moved on to the following a pair of fixed claw place of closing on of rib blade plate 100, repeats above-mentioned steps, up to all fixed claws all hold hold rib tightly till.
