Abstract

The utility model discloses a push-pull quick movable wrench comprising a fixed wrench law which is provided with a handle at the tail, a movable wrench jaw and an adjusting lead screw; the top of the fixed wrench jaw is provided with a slide way; the bottom of the movable wrench jaw is provided with a rack; the rack is arranged in the slide way and is mutually matched with the adjusting lead screw; the outer wall of the adjusting lead screw is provided with a strip-shaped slot along the axis direction of the adjusting lead screw; the depth of the strip-shaped slot corresponds to the rack on the movable wrench jaw; and when the strip-shaped slot rotates to the rack, the movable wrench jaw can directly slide along the slide way. The push-pull quick movable wrench has simple and practical structure, can save 70 percents of operation time, greatly improves the working efficiency, and has basically the same cost as an ordinary movable wrench.

Description

Plug-type fast monkey spanner

Technical field

The utility model relates to hardware ﹠ tools, relates in particular to a kind of spanner.

Background technology

Monkey wrench is the maintenance tool that people often use, and according to the bolt that turns different model, can carry out regulated at will to the openings of sizes of monkey wrench, for not movable common wrench, is easy to use manyly.

Referring to Fig. 1, monkey wrench of the prior art is made of fixedly pulling mouth 2, Flexible spanner mouth 3 and adjusting leading screw 4 of afterbody band handle 1, wherein adjusting leading screw 4 is embedded into and fixedly pulls in mouthfuls 2 and can relative fixed pull mouthfuls 2 and rotate, fixedly pull mouth 2 and have slideway, Flexible spanner mouth 3 bottoms have tooth bar 5, tooth bar 5 is inserted in the slideway and is cooperatively interacted with adjustment leading screw 4, adjust and to drive tooth bar 5 and Flexible spanner mouth 3 when leading screw 4 rotates and move along slideway, can adjust the opening and closing degree of fixedly pulling between mouth 2 and the Flexible spanner mouth 3, i.e. adjustment is pulled the size of mouth to adapt to the different bolt of size.

Yet this monkey wrench also has certain defective: the speed of regulating opening is slow, need be with after the adjustment leading screw turn multi-turn on the plank, the opening of monkey wrench just can reach the degree that needs, restricted operating efficiency greatly, this is because the traditional activity spanner structurally has due to the defective.

Summary of the invention

The utility model provides a kind of mouth of adjustable plate efficiently size, and plug-type very easily fast monkey spanner works together.

A kind of plug-type fast monkey spanner, comprise fixedly pulling mouth, Flexible spanner mouth and adjusting leading screw of afterbody band handle, fixedly pull a mouthful top and have slideway, Flexible spanner mouth bottom has tooth bar, tooth bar is inserted in the described slideway and with adjusting leading screw and is cooperatively interacted, and has on the outer wall of described adjustment leading screw along the bar-shaped trough of adjusting the leading screw axis direction, and the tooth bar on the degree of depth of this bar-shaped trough and the Flexible spanner mouth is corresponding, when bar-shaped trough turned to the tooth bar place, the Flexible spanner mouth can directly slide along slideway.

The utility model is transformed the adjustment leading screw in the normal activity spanner, open a bar-shaped trough that is parallel to adjustment leading screw axis at the screw thread of adjusting on the leading screw outer wall, bar-shaped trough connects all screw threads, the bar-shaped trough degree of depth equals to adjust the thread depth on the leading screw outer wall, and the bar-shaped trough bottom is the root of screw thread.

Turn to bar-shaped trough when corresponding with tooth bar when adjusting leading screw, the Flexible spanner mouth is not adjusted leading screw and is limited, random push-and-pull portable plate mouth, when push-and-pull pull mouthful to need big or small the time, leading screw is adjusted in turn forward, pulls a mouth meeting fishbolt at this moment.

The practicality of the plug-type fast monkey spanner simple structure of the utility model can save for 70% operating time, has improved operating efficiency greatly, and cost is the same substantially with common monkey wrench.

Description of drawings

Fig. 1 is the structural representation of spanner in the prior art;

Fig. 2 is the structural representation of the plug-type fast monkey spanner of the utility model.

The specific embodiment

Fixedly pull mouth 2, Flexible spanner mouth 3 and adjust leading screw 4 referring to the plug-type fast monkey spanner of Fig. 2 the utility model.Adjusting leading screw 4 is embedded into and fixedly pulls in mouthfuls 2 and can relative fixed pull mouthful 2 rotations, the afterbody of fixedly pulling mouth 2 has handle 1, fixedly pull mouthful 2 tops and have slideway, Flexible spanner mouth 3 bottoms have tooth bar 5, tooth bar 5 is inserted in the slideway with adjusting leading screw 4 and is cooperatively interacted, and adjusts can drive tooth bar 5 and Flexible spanner mouth 3 when leading screw 4 rotates and move along slideway.

On the outer wall of adjusting leading screw 4, have along the bar-shaped trough 6 of adjusting leading screw 4 axis directions, tooth bar 5 on the degree of depth of bar-shaped trough 6 and the Flexible spanner mouth 3 is corresponding, basically the degree of depth of bar-shaped trough 6 equals to adjust the thread depth on leading screw 4 outer walls, bar-shaped trough 6 connects all screw threads, like this when bar-shaped trough 6 turns to tooth bar 5 places, Flexible spanner mouth 3 is not adjusted leading screw 4 restrictions, arbitrarily push-and-pull portable plate mouth 3 directly slides along the slideway of fixedly pulling mouth 2, when pulling mouth and reach need big or small, slightly leading screw 4 is adjusted in turn, make stagger tooth bar 5 on the Flexible spanner mouth 3 of bar-shaped trough 6, pulling this moment mouthful can a fishbolt.

Claims

1. plug-type fast monkey spanner, comprise fixedly pulling mouth, Flexible spanner mouth and adjusting leading screw of afterbody band handle, fixedly pull a mouthful top and have slideway, Flexible spanner mouth bottom has tooth bar, tooth bar is inserted in the described slideway and with the adjustment leading screw and is cooperatively interacted, it is characterized in that: have on the outer wall of described adjustment leading screw along the bar-shaped trough of adjusting the leading screw axis direction, tooth bar on the degree of depth of this bar-shaped trough and the Flexible spanner mouth is corresponding, when bar-shaped trough turned to the tooth bar place, the Flexible spanner mouth can directly slide along slideway.

2. plug-type fast monkey spanner as claimed in claim 1 is characterized in that: the described bar-shaped trough degree of depth equals to adjust the thread depth on the leading screw outer wall.
