Description
Technical field
The utility model relates to spanner field, has particularly related to a kind of pipe wrench structure.
Background technology
Pipe wrench of the prior art, if the patent No. is for shown in the United States Patent (USP) of US4967612, body is fixed with the block that is pivoted, is provided with the fit portion for fit screw piece in the block that is pivoted.
This pipe wrench major function be: body is provided with the block that is pivoted, and as shown in Figure 3, being pivoted, block can closing be on body again after fit screw piece, and as shown in Figure 1, such pipe wrench just turn can be arranged on screw piece on pipe wrench.But the shortcoming of this patent structure is:
Please refer to Fig. 1 of this patent, 4 adjacent edge faces of this block that is pivoted all are coated on screw piece, after pipe wrench turn certain angle, this block that is pivoted needs to be separated with screw piece, after pipe wrench is rotated counterclockwise certain angle, just can turn after this be pivoted block and screw piece again phase fit, be namely pivoted to need between block and screw piece repeatedly repeatedly to throw off, fit, add the man-hour of turn screw piece.
And for example US Patent No. 6978701B1, shown in its Fig. 6 d, body is also provided with one and is pivoted block.But shortcoming is in this patent: consult Fig. 6 d, 4 adjacent edge faces of this block that is pivoted also are coated on screw piece, be namely pivoted to need between block and screw piece repeatedly repeatedly to throw off, fit, add the man-hour of turn screw piece, the same with patent US4967612.
Again shown in See U. S. Patent US6978701B1, Figure 12 a to 12g, which disclose a body, and on connector, the other end of this connector is provided with the block that is pivoted.But the shortcoming of this patent is:
1. refer to Figure 12 f in this patent, this figure is three-dimensional exploded view, connector is provided with the first lamellar body, first lamellar body epirelief is provided with bipole body, the end of bipole body combines with first lamellar body, and bipole body is arranged on the first lamellar body and not easily processes, and bipole body 78 needs to be welded on respectively on the first lamellar body, nonetheless, the first lamellar body and the end being not easily combined in bipole body.First lamellar body should have latch closure to be fastened on bipole body, make this first lamellar body be combined in bipole body end, but such infrastructure cost is very high.
2. refer to Figure 12 f, body is connected with connector, and the connector other end is provided with the block that is pivoted, the structure that this three elements connect successively, have between connector and body and relatively rotate, be pivoted between block with connector and also have relative rotation, this comparatively complicated structure that is pivoted.As shown in Figure 12 e, body, connector and the being pivoted block that to be pivoted when being pivoted successively between block three is sent out displacement path and is comparatively difficult to determine.
3. refer to Figure 12 c, 12b and 12a, as shown in fig. 12 c, if connector and the very fast pivotable return of body, namely this end can be repositioned to a recess of body, as figure 12 a shows.Therefore this pipe wrench structure there are three structures that are pivoted namely can produce this turn disappearance.
