Abstract

The utility model relates to a multipurpose spanner which not only can be used as an adjustable spanner, but also can be used as a pipe wrench. An existing adjustable spanner and an existing pipe wrench adopt the structure of rotating and adjusting the size of a toothed mouth by spiral teeth; the operation of the structure wastes power, and the slipping phenomenon is produced easily. The utility model mainly comprises adjustable jaws (1) and (5) provided with a plurality of straight lines with concavity, a handle (3) whose both ends are provided with involute spiral teeth (30) and (33), and pins (2) and (4) movably integrate the handle (3) and the jaws (1) and (5) into a whole. The utility model has the advantages of simple structure and reliable operation.

Description

Combination wrench

The utility model relates to a kind of active spanner usefulness of both can having done, and can do the combination wrench that the pipe wrench is used again.

Existing monkey spanner 6 mainly is made up of wrench body 61, movable bayonet socket 62, screw rod 63, a rotatable screw rod 63 is installed in wrench body 61 head stage casings, the spiral shell tooth section and screw rod 63 interlocks of movable bayonet socket 62, active bayonet socket 62 is moved up and down along the screw rod direction of rotation, thereby reach the size of regulating the monkey spanner mouth, to the nut of different size, not only can tighten but also can come loose; Existing pipe vice 7 is mainly by wrench body 71, active bayonet socket 72, screw rod 73 is formed, a rotatable screw rod 73 is installed in wrench body 71 head stage casings, the spiral shell tooth section and screw rod 73 interlocks of movable bayonet socket 72, active bayonet socket 72 is moved up and down along screw rod 73 direction of rotation, thereby regulate the size of jaw, its pipe of various sizes of can tightening or come loose, adjustable wrench and pipe vice are all regulated the bayonet socket size with screw rod, screw rod is easy to generate skidding, reliable inadequately when fastening or dismounting hexagonal (hexagon)nut or pipe, put off until some time later that manually to twist screw rod also inconvenient, especially when work high above the ground, if wrench or pipe vice break down, can cause the accident; The structure of adjustable wrench and pipe vice is complicated, and part is many in addition, Heavy Weight, cost height; Spanner and pipe vice can not be general mutually.

The purpose of this utility model provides a kind of simple in structure, and is easy to operate, both can do active spanner usefulness, can do the Multipurpose templet hand that pipe vice is used again.

The utility model is to realize like this.

The utility model mainly contains jaw, handle, pin to be formed, and the jaw profile is the ellipse garden shape of opening, and last point is big down, in be many straight suede sections of inside concavity opening, each straightway size difference wherein leans on two straight lines of both ends open to parallel; The jaw lower end side is opened an elongated slot, and there is a through hole elongated slot lower end; Handle is direct rod shape, and the two ends head of bar has a through hole, and head is that the center outwards is off-centre with the through hole, and the outer ellipse garden of the jaw approximate equidirectional of line has evagination involute spiral shell tooth, and wherein the distance of mind-set spiral shell between cog is become heavy gradually by little.

The pin of garden shape penetrates the through hole of jaw, handle, and jaw, handle are linked as rotating relatively one, and handle spiral shell tooth rotates around pin, and then it can block the nut or the pipe of ascending different size; Handle spiral shell tooth may be stuck in the inclined-plane of jaw elongated slot, prevents that handle from coming off in the jaw outside; Handle spiral shell tooth and jaw are clamped nut or pipe, and the opening of jaw is towards the left side, and the clockwise direction handle of walking around is then tightened nut or pipe; If the opening of jaw is towards the right, counter-clockwise rotary handle, nut or pipe then come loose; If jaw moved down around pin transport out of the spiral shell tooth, then can make solid wrench and use.

The jaw of different range size can be installed in the two ends of handle, thereby can form the combination wrench series of products of different size scope.

The utility model advantage is:

1, utility model by three of jaws, handle, pin in addition parts forms, leather falls traditional screw rod and regulates the way of jaw size by artificial turn, simple in structure, in light weight (be use always wrench weight 1/2), easy to carry;

2, adopt the spiral shell tooth to match, need not to regulate with polygonal different size straight line in the jaw, easy to use and reliable, skidding can be do not produced, and series of products can be formed;

3, the utility model both can have been done active spanner usefulness, can do pipe vice usefulness again, reached the purpose that a spanner is used more.

Below in conjunction with drawings and Examples the utility model is further described.
