Abstract
The invention provides an adjustable pull rope wrench. The problems in a common adjustable wrench that threads on the worm are easy to damage after a worm is used for a period of time due to the fact that the openness is adjusted through the worm so as to adapt to nuts of different diameters and the service life of the common movable wrench is shortened are solved. The adjustable pull rope wrench comprises a wrench body, a handle is arranged at one end of the wrench body, a wrenching portion is arranged at the other end, the wrenching portion is provided with a fixed jaw and a sliding groove, the sliding groove extends to the bottom end of the fixed jaw, a movable jaw is sleeved in the sliding groove, and the movable jaw can move in the sliding groove under the effect of outer force. The adjustable pull rope wrench is characterized in that two ends of the movable jaw are connected with a pull rope, the pull rope is connected with a roller, and the roller is arranged on the handle and connected with a crank handle. The adjustable pull rope wrench is an installing and detaching tool.
Description
technical field:
The present invention relates to a kind of instrument, be specifically related to a kind of adjustable rope-pulling spanner.。
background technology:
Spanner is a kind of conventional installation and removal instrument.Utilize lever principle to twist bolt, screw, nut and other screw threads and tightly hold the opening of bolt or nut or the hand tools of trepanning firmware.Spanner is conventionally shaped with clamp holder portion and applies external force shank and apply external force in the one or both ends of shank, just can twist opening or trepanning that bolt or nut are held bolt or nut.During use, along screw thread rotation direction, at shank, apply external force, just can twist bolt or nut.
Conventional adjustable wrench adopts worm screw to regulate opening degree to be convenient to adapt to the nut of different-diameter, but the situation of the thread damage on worm screw easily occurs worm screw after using a period of time, causes spanner to reduce service life.
summary of the invention:
The object of the invention is provides a kind of adjustable rope-pulling spanner for the problem of above-mentioned existence, the convenient opening degree that regulates spanner, and reliable operation, long service life.
Above-mentioned object realizes by following technical scheme:
Adjustable rope-pulling spanner, comprise wrench body, one end of described wrench body is handle, and the other end is pulling part, described pulling part has fixedly Hubei Province and a chute, described chute extends to fixed jaw bottom, and described chute the inside is set with movable Hubei Province, and described movable Hubei Province can be moved under external force in chute, the two ends in described movable Hubei Province connect stay cord, described stay cord connects cylinder, and described cylinder is arranged on described handle, and described cylinder connects crank handle.
Described adjustable rope-pulling spanner, the diameter of described cylinder is greater than the length of described chute.
Beneficial effect:
The present invention rotates cylinder according to the size of different nuts to be screwed by rotating crank handle in the process of using, thereby drive stay cord to pull movable Hubei Province to move in chute, when treating that movable Hubei Province moves to suitable position, fixedly crank handle is held handle and is carried out work, due to stay cord can be convenient for changing after damaging and cost low, do not affect service life of spanner integral body.
accompanying drawing explanation:
Fig. 1 is structural representation of the present invention.
In figure: 1, handle, 2, pulling part, 3, fixing Hubei Province, 4, chute, 5, movable Hubei Province, 6, stay cord, 7, cylinder, 8, crank handle.
the specific embodiment:
Embodiment 1:
As shown in Figure 1: adjustable rope-pulling spanner of the present invention, comprise wrench body, one end of described wrench body is handle 1, the other end is pulling part 2, described pulling part has fixedly Hubei Province 3 and a chute 4, described chute extends to fixed jaw bottom, described chute the inside is set with movable Hubei Province 5, described movable Hubei Province can be moved under external force in chute, the two ends in described movable Hubei Province connect stay cord 6, described stay cord connects cylinder 7, and described cylinder is arranged on described handle, and described cylinder connects crank handle 8.
Embodiment 2:
Adjustable rope-pulling spanner described in embodiment 1, the diameter of described cylinder is greater than the length of described chute.
The disclosed technological means of the present invention program is not limited only to the disclosed technological means of above-mentioned technological means, also comprises the technical scheme being comprised of above technical characterictic.Unaccomplished matter of the present invention, belongs to those skilled in the art's common practise.
