Description

The pipe wrench of tool counterweight

Technical field

The present invention relates to a kind of pipe wrench, refer to especially a kind of pipe wrench of tool counterweight.

Background technology

Consult shown in Fig. 1, show the schematic diagram of the pipe wrench of common tool Sustain structure, it is mainly comprised of a main handle 11, the secondary handle 13 of a movable jaw 12,, an elastic component 14, a locating part 15 and a moving part 16, wherein:

Described main handle 11 one end are provided with a fixed jaw 111, the other end is established one and is worn portion 112, and this fixed jaw 111 and this are worn and between portion 112, are provided with a U-shaped groove 113, this wear portion's 112 spiral shells establish a head part 114 mutually should groove 113, this is worn portion's 112 one end connections one and holds portion 115, portion's 115 moulding one hook ribs 116 should be held mutually in these groove 113 bottom land middle sections, and this is held portion 115 one end and connects a pivot portion 117.

The folder portion 121 of relative these main handle 11 fixed jaws 111 of described movable jaw 12 one end moulding one, the first pivot portion 122 and the second pivot portion 123 of pivot portion 117 pivot joints of the other end two sides difference moulding one and this main handle 11.

Described secondary handle 13 has a U-shaped groove 131, these pair handle 13 one end are adjacent establish one with the first pivot portion 132 and the second pivot portion 133 of the second pivot portion 123 pivot joints of this movable jaw 12, and these the second pivot portion 133 one end connect a splenium 134.

Described elastic component 14 1 end hooks are placed on the hook rib 116 of this main handle 11, and another end hook is placed between the first pivot portion 122 and this second pivot portion 123 of this movable jaw 12.

Described locating part 15 has a U-shaped groove 151, adjacent one first pivot portion 152 and the second pivot portion 153 of establishing in these locating part 15 one end, this other elongation moulding one Sustain structure 154 of the first pivot portion 152, the first pivot portion 152 and the second pivot portion 133 pivot joints of this pair handle 13 of this locating part 15 are placed in the groove 131 of this pair handle 13; Sustain structure 154 is sheet, and this Sustain structure 154 is that the bottom land elongation moulding by this locating part 15 forms, and makes on corresponding groove 131 bottom lands that are limited in this pair handle 13 of this Sustain structure 154.

Described moving part 16 is T word shape, a pivot portion 161 is established in these moving part 16 one end, the other end is established a card division 162, this moving part 16 middle section moulding one tops 163 mutually should secondary handle 13 groove 131 bottom lands, the pivot portion 161 of this moving part 16 is embedded in the groove 151 of this locating part 15 and these the second pivot portion 153 pivot joints, and this card division 162 is supported and terminated in this head part 114 one end pivotly.

Accordingly, the groove 131 that described fixture directly mutually should secondary handle 13 by the Sustain structure 154 of these locating part 15 top moulding carries out spacing and then provides space to save to be convenient to assemble relative saving material cost; Yet it uses situation still to have the defect that need improve immediately in reality:

As shown in Figure 1, this pipe wrench is to be clamping state, when this pipe wrench is opened, except this pair handle 13 can be away from state with respect to this main handle 11, this locating part 15 also can be mutual pivot pendulum and be bending with this moving part 16, in addition, this locating part 15 also can be take this first pivot portion 152 as pivotable center pivotable one angle and then be pushed against this pair handle 13, make this pair handle 13 accelerate pivot pendulum outward, yet, because the Sustain structure 154 of this locating part 15 is one plane, and this Sustain structure 154 is excessively far away apart from U-shaped groove 131 groove bottom of this pair handle 13 away from one end 155 of the first pivot portion 151, therefore, cause this pipe wrench when opening, locating part 15 cannot push against this pair handle 13 immediately, the underspeed that this pair handle 13 is opened, affect operating efficiency.
