Abstract

The utility model discloses a monkey wrench, which comprises an annular claw with a tubular guiding connecting handle, an adjustable clamping jaw and a handle. The handle connects with the connecting handle of the annular claw by an annular groove at the front end of the handle and a connecting pin, and the handle rotates relative to the annular claw. One end of the adjustable clamping jaw is a guiding end, and the other end is a screw rod; the screw rod matches with the screw thread in the core part of the handle. When the user twists the handle, because of the limitation of the guiding part, the adjustable clamping jaw only can extend out or retract and can not rotate relative to the annular claw, and thus, the purpose that screws or nuts are clamped or unclamped are realized. The monkey wrench has good locking performance, and has not slip phenomenon. The utility model is suitable for dismounting the screws and nuts of obsolete equipment.

Description

Monkey wrench
The utility model relates to a kind of adjustable wrench, and it belongs to the hand tools technical field.It comprises ring pawl, adjustable jaw and handle.
The present adjustable wrench that uses comprises that one is connected in the fixed claw of one, an adjustable jaw and an adjusting double-screw bolt with handle.Its advantage is to use scope wide, and is during adjusting, flexible.Its weak point is that cost is higher, and locking function is relatively poor, especially when the screw of demolition obsolete equipment or nut, tends to occur skidding.Like this, not only make troubles the arm of also damaging easily to dismantlement work.
The purpose of this utility model is to overcome weak point in the above-mentioned prior art and provides a kind of low cost of manufacture, locking function by force and be not prone to the adjustable wrench of skidding in use.
The purpose of this utility model realizes by following measure, a kind of adjustable wrench.It comprises ring pawl, adjustable jaw and handle.The ring pawl has a tubular guidewire to connection handle.The guide end of adjustable jaw places ring pawl tubular guidewire in connection handle, and its other end is screw rod and matches with handle core screw.Handle by its front end cannelure and is connected the connection handle of locking with encircling pawl and links to each other.Like this, when the turn handle, the led restriction at position of adjustable jaw is only stretched out with respect to the ring pawl or is withdrawn, and can not relatively rotate.When adjustable jaw stretches out, with the ring pawl screw or nut are clamped, when withdrawal, promptly unclamp.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the spanner front view.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is another embodiment accompanying drawing.
The utility model is described in further detail below in conjunction with the embodiment accompanying drawing:
With reference to Fig. 1, handle 1 links to each other to connection handle 5 with the tubular guidewire of ring pawl 4 by cannelure 2, the junction of the edges of two sheets of paper connecting pin 3 of its front end.Handle 1 can only be rotated with respect to ring pawl 4.The guide end 7 of adjustable jaw 6 places the tubular guidewire of ring pawl 4 in connection handle 5, and its other end is screw rod 8 and matches with the core screw 9 of handle 1.The hand grip portion annular knurl 10 of handle 1 is so that use.In order to lock fast or to unclamp, screw rod 8 and screw 9 can be made into multiple thread.
With reference to Fig. 2, the guide end of adjustable jaw 6 has a pair of and the parallel relative guide surface 11 of its axis, and it matches to the opening that is bordering on rectangle 12 of connection handle 5 with the tubular guidewire of ring pawl 4, when turn handle 1, make adjustable jaw 6 stretch out or withdraw, and can not relatively rotate with respect to ring pawl 4.For the ease of using, upper and lower lip 13 front and back of the rectangular aperture 12 suitable distance that staggers.
With reference to Fig. 3, the guiding of adjustable jaw 6 can realize by means of guide finger 14 and gathering sill 15.Handle 1 can connect by means of the connecting pin 16 perpendicular to handle axis to being connected of connection handle 5 with the tubular guidewire of ring pawl 4.In order to improve the locking function of spanner, ellipticity or polygon are made by the inner arc portion 18 of ring pawl 4, but with adjustable jaw 6 corresponding parts be a plane 17.Help clamping like this to head of screw or nut 19.For the ease of the dismounting maintenance, connecting pin 16 is preferably selected jackscrew for use.
It is lower that spanner provided by the utility model is manufactured cost, and during use, locking property is good, is not prone to skidding.The dismantlement work that is particularly useful for obsolete equipment screw, nut.
