Step 7, such as shown in figure (M), this device is extracted to the outer end of workpiece 12, and workpiece 12 is separated with this device, completes work Part 12 is tightened.
The principle of the totally-enclosed anti-surface damage device for screwing up shown in four technical schemes of this utility model is:
1st, first jaw 2, the second jaw 3 and handle 4 are to connect into one by the round pin of three gaps cooperations to close The device for screwing up of conjunction, all two components connected by round pin are all that for both shoulders, another side member is middle single to a side member The structure of shoulder, is gap cooperation between round pin and component hole, and side pieces can be rotated around round pin or slided, while two jaws Neonychium 11 is fixed in inner side by draw-in groove, and by neonychium 11 workpiece 12 is contacted, and neonychium 11 both plays transmission torsion, rotation circle The effect of workpiece 12, plays a part of to prevent the surface damage of workpiece 12 again.Because two jaws inner side is a pair symmetrical circular arcs Inwall, the thickness after circular arc inwall radius compresses according to the radius of workpiece 12 and neonychium 11 is configured, and increases neonychium 11 With the contact area and frictional force of workpiece 12.
2nd, using the operation of this device for screwing up:
Tighten workpiece 12:When turning clockwise handle 4 to the direction of the side of the first jaw 2, handle 4 fixes round pin 5 around first (or folding round pin 1) rotates, and drives elongated hole inwall of the slip round pin 6 on the second jaw 3 to roll from inside to outside or slide, gradually The first jaw 2 and the second jaw 3 are tightened up, by the workpiece pressing 12 of neonychium 11;The anglec of rotation and revolving force of handle 4 is bigger, It is nearer that two jaws are received, and the power of workpiece pressing 12 is bigger, and the frictional force for passing to workpiece 12 by neonychium 11 is bigger, rotates work The strength of part 12 is also bigger.
Unclamp workpiece 12 and return device for screwing up:To the side of the second jaw 3 direction rotate counterclockwise handle 4 when, handle 4 is around One fixes round pin 5 (or folding round pin 1) rotation, drives elongated hole outer wall ecto-entad of the slip round pin 6 on the second jaw 3 to roll Or slide, the first jaw 2 and the second jaw 3 unclamp workpiece 12;Continue to rotate, first fixes round pin 5 (or folding round pin 1) promotes Second jaw 3 and whole device for screwing up return initial position,
Workpiece 12 is tightened in circulation:Turn clockwise handle 4 to the direction of the side of the first jaw 2 again again, realize workpiece pressing 12nd, rotational workpieces 12, release workpiece 12, device for screwing up return the circulate operation of initial position, until tightening workpiece 12.
Because the direction of rotation of handle 4 is identical when workpiece pressing 12 tightens workpiece 12 with rotation, unclamps workpiece 12 and return The direction of rotation of handle 4 is identical during initial position, so can continuously be rotated with both forward and reverse directions during workpiece 12 is entirely tightened, It is rapidly completed and tightens operation.
When the 3rd, to the direction rotary handle 4 of the side of the first jaw 2, the connecting side of the first jaw 2 and the second jaw 3 and handle 4 Respectively it is subject to a top one to draw contrary power, because the first jaw 2 and the opposite side of the second jaw 3 are by (or the second fixation round pin of folding round pin 1 13) connect, so the strength major part of two jaws itself rotational workpieces 12 cancels each other, remaining small part is by neonychium 11 Frictional force is offset, and the strength of turn handle 4 is bigger, and thrust is bigger, so turn handle 4 is made after two jaw workpiece pressings 12, Will not sliding between two jaws and workpiece 12.
