Abstract
The utility model aims to provide a ratchet wrench with simple structure, light weight and good portability and capable of saving effort and time and changing direction. The ratchet wrench comprises a handle, a joint, a cover plate, a ratchet, a sleeve-lengthened pipe and pawls, wherein the sleeve-lengthened pipe sleeved in the ratchet; pins are axially arranged between the sleeve-lengthened pipe and the ratchet; the ratchet is sleeved on the cover plate through a convex ring thereof; the joint has a cavity in which a spring and a top pillar are arranged; pawl pin holes are arranged on the cover plate; the pawls are connected with the cover plate through fixed pins; and the cover plate is fixedly connected with the joint. By using the ratchet wrench, the rotation direction of the ratchet wheel can be set by rotating long legs of the pawls based on whether a nut is screwed or detached, and the nut can be fixed and detached conveniently by holding the handle by hand to make reciprocating movement, thereby improving the work efficiency.
Description
Technical field
The utility model relates to a kind of hand-operated tools of fastening nut, a kind of specifically ratchet spanner.
Background technology
In the railway electrification work progress, need to use a large amount of nuts in the installation of iron tower, the installation of head span suspension and foundation bolt fixing, the size of these nuts is big, when common spanner is tightened fixedly, relatively require great effort, and when running into obstacle, can not change direction, spanner can only be taken off from nut, again be set to then tighten on the nut fixing, such action repeatedly several times after, could nut is fixing fastening.This spanner uses inconvenient, and wastes time and energy.
The utility model content:
The purpose of this utility model just provides a kind of simple in structure, and is light, laborsaving, save time, and can change the ratchet spanner of direction.
Realize that the technical scheme that the utility model purpose adopts is: a kind of ratchet spanner, comprise handle (1), joint (2), cover plate (10), ratchet (9), sleeve extension pipe (7) and ratchet (6), sleeve extension pipe (7) is sheathed in the ratchet (9), axially be provided with pin (8) between sleeve extension pipe (7) and the ratchet (9), ratchet (9) is socketed on cover plate (10) by its protruding circle (12); Described joint (2) is provided with a cavity, is provided with top spring (3), fore-set (4) in it, and cover plate (10) is provided with the ratchet pin-and-hole, and ratchet (6) is connected with cover plate (10) by fixing pin (5); Cover plate (10) and joint (2) Joint.
Described cover plate (10) can weld with the connected mode of joint (2).
Described ratchet (6) is two-way adjustable ratchet, about respectively be provided with long pin (13), be the isoceles triangle shape near the end face of joint, be arranged with the short pin (14) of two screens near ratchet (9) one ends.
Ratchet (9) links together by the end of pin (8) with sleeve extension pipe (7), the other end of sleeve extension pipe (7) is cannulated sleeve (11), pin (5) is fixed ratchet (6), one short pin (14) of ratchet (6) can be inserted in the groove of ratchet (9), the long pin (13) of ratchet (6) stretches out cover plate (10), and a part is stayed the outside.Can prevent that by the top power effect of fore-set (4) ratchet (6) is loosening in the lower end of ratchet (6), top spring (3) is housed in fore-set (4) bottom.Cover plate (10) wraps in inside with ratchet (9), ratchet (6), fore-set (4) and top spring (3).Joint (2) links together fore-set (4), cover plate (10) and handle (10).Skid in the handle place in order to prevent to operate, and can when increasing frictional force, also improve and hold comfort level like this at the about 10 centimetres of part annular knurls of handle (1).
The significant advantage of the utility model: cannulated sleeve is set on the nut to be rotated, the still dismounting of tightening according to nut, by the long pin that rotates ratchet the ratchet rotation direction is set, holding handle then moves back and forth, can conveniently realize the fixing and dismounting of nut, improve operating efficiency.
