The specific embodiment
See also Fig. 1 to shown in Figure 3, the monkey wrench 1 of the prevented movable jaw inclination that the utility model embodiment is provided includes:
One body 10 has a leader 11 and a fixed jaw 12; This body 10 is at the chute 13 that has a horizontal expansion near an end of this fixed jaw 12, its two end and upper end a part of opening-like; One holds hole 14, is located at this body 10, is positioned at the below of this chute 13, and its upper end is communicated with this chute 13.
One adjusts worm screw 21, is located in the appearance hole 14 of this body 10, and its right-hand member is equiped with a worm screw spring 22, and the one end is resisted against this adjustment worm screw 21, and the other end is resisted against this body 10; One worm screw pin 23 passes this body 10, this adjustment worm screw 21 and this worm screw spring 22, makes this adjustment worm screw 21 free to rotate.
One movable jaw 30, bottom have a neck 31, two sides and respectively have a block 312.The bottom of this neck 31 has one and is cylindrical slide block 32, and this neck 31 is located in the chute 13 of this body 10 with this slide block 32, make this movable jaw 30 can be in preset range near or away from this fixed jaw 12.The slide block 32 of this movable jaw 30 is provided with a tooth bar (rack) 33, adjusts worm screw 21 engagements with this, makes when this adjustment worm screw 21 of rotation can drive this movable jaw 30 and moves.
The elastic strip body 41 that without exception takes the shape of the letter U respectively has a supporting part 411 at its two end, and respectively has an opening 412 at the rear of this two supporting part.This elastic strip body 41 is sheathed on the end of these movable jaw 30 necks 31 near this fixed jaw 12.At this moment, the block 312 of this neck 31 is arranged in the opening 412 of this elastic strip body, and this elastic strip body 41 is fixed on this movable jaw 30.Two supporting parts 411 of this elastic strip body 41 are hanging shape, and the outer end is resisted against respectively on two side wall surfaces of these body 10 chutes 13.
By above structure of taking off, this elastic strip body 41 can be filled up the clearance of 13 of this movable jaw 30 and this chutes really, and prevents that this movable jaw 30 from producing the problem of inclinations.
In addition, the chute 13 that the flexible supporting part 411 of these elastic strip body 41 tools is resisted against this body 10 also can provide the frictional force (f) (seeing also Fig. 2) of a little, reducing this movable jaw 30 after being adjusted to the precalculated position, backlash (clearance of the teeth) (c that is produced when adjusting worm screw 21 engagements because of the tooth bar 33 of movable jaw 30
1), this movable jaw 30 before and after producing, is rocked moving direction, and cause opening size (s) to change, produce the phenomenon of disturbing when making the same nut of repeated rotation.
This is apparent and easy to know, and this U-shaped elastic strip body 41 also can be installed in the end of movable jaw 30 necks 31 away from fixed jaw 12, as shown in Figure 4, also or two ends one U-shaped elastic strip body (not shown) respectively is set, so all can reach identical effect.
It is shown in Figure 6 to see also Fig. 5, the monkey wrench 2 of the prevented movable jaw inclination that the utility model second embodiment is provided, its primary structure is roughly identical with first embodiment 1, only, the monkey wrench 2 of second embodiment has the two metallic elastic lamellar bodies 53,54 that are the lengthy motion picture shape, and its middle section position is fixed in the precalculated position of these movable jaw 52 necks 521 both sides in the mode (mode that can also be adhesive certainly) of spot welding (spot welding).Respectively two sides of this elastic strip body 53,54 respectively have a supporting part 531,541 that is hanging shape and are resisted against this body 51 sliding two side wall surfaces of 511 that increase.
See also shown in Figure 7ly, the monkey wrench 3 of the prevented movable jaw inclination that the utility model the 3rd embodiment is provided is the extension of second embodiment, and each elastic strip body 63,64 only has a supporting part 631,641.
See also shown in Figure 8, the monkey wrench 4 of the prevented movable jaw inclination that the utility model the 4th embodiment is provided, it also is the extension of second embodiment 2, its principal character is that a hole 722 is set on the neck 721 of movable jaw 72, the stage casing of two elastic strip bodies 73,74 has a joint pin 732,742, be located in the hole 722 of this movable jaw 72 (this joint pin 732,742 and this hole 722 can be friction tight state), make this two elastic strip body 73,74 be located at two sides of these movable jaw 72 necks 721.Respectively this elastic strip body 73,74 has two supporting parts 731,741, and is identical with previous embodiment, is resisted against on the side wall surface of chute 711 of body 71.
Propose explanation a bit at this, the joint pin 732,742 of two elastic strip bodies 73,74 among second embodiment also can be made as socket shape (not showing) mutually in figure, and this is the simple conversion of prior art, holds and does not give unnecessary details.
The utility model has the advantage of: simple structure, easy to manufacture, can really eliminate movable jaw And the clearance between the chute, and the phenomenon that can avoid movable jaw to roll.
