Abstract

The utility model relates to a high-efficient multi-purpose adjustable wrench. A rotatable and changeable wrench jaw with teeth is added on a small mouth; simultaneously the small mouth does not use the original short screw and the teeth of the short screw as the means of adjusting the dimension of an opening any longer, but uses a flat yarn nut engaged with the screw with a large lead spiral groove in a longitudinal groove at the handle portion of the wrench body. Under the impulse of the handle which has digital reticles to limit working position, the contact position of the upper end face of the flat yarn nut and the bottom plane of the small mouth is changed to achieve quickly and accurately adjusting the dimension of the wrench opening. Because the wrench opening at the head of the wrench body is provided with teeth, the teeth on the wrench opening and the teeth on the changeable wrench opening which can rotate when suffering torque force together bite tightly a pipe fitting and operate the pipe fitting. A ring hole opened at the tail end of the handle portion of the wrench body can operate correspondingly dimensional bolts and nuts; the high-efficient multi-purpose adjustable wrench has the function of a ring spanner. The utility model is a multi-purpose high-efficient wrench.

Description

High-efficient multi-purpose adjustable wrench

The utility model is used for the Assembly And Disassembly of securing member, tube members.

Be unable to do without spanner in industrial and agricultural machinery production, the assembling process, especially need the place of conversion wrench opening size often, all use adjustable wrench.It is to regulate the wrench opening size by short worm screw and the tooth of chewing for a short time.For guaranteeing opening size and bolt, nut opposite side consistent size, often needing examination back and forth to transfer several times could be suitable, and this has just influenced operating efficiency; Simultaneously, because common adjustable wrench mostly has only a function, the tube members of can not removing stage makeup and costume.

The purpose of this utility model is that a kind of improved adjustable wrench will be provided, and it can operate required opening size quickly and accurately, does not need to adjust back and forth, can also use as double offset ring spanner, pipe wrench.

The purpose of this utility model is achieved in that pulling the body shank at spanner has cannelure, is equipped with to be with big helical pitch spiral fluted screw rod the female engagement of a screw rod and a flat filament in the groove.When promoting skewer and go into handle on the big helical pitch helicla flute bearing pin, the screw rod rotation also drives the flat filament mother and slides up and down; The plane contact of chewing for a short time that the body head is free to slide can and can pulled at diverse location in the screw upper surface, because the hand-deliver that female upper surface of flat filament and Xiao Zui are free to slide is angled, and by the female upper surface of flat filament pinning on certain orientation; The handle position that lead-screw rotates is limited by pulling the digital groove that the body cannelure covers, as long as handle is shifted required groove onto, just chewing for a short time of monkey wrench is limited on the required opening size at once.

Because pulling body shank tail end has plum blossom hole, so the function of double offset ring spanner is arranged again.

Have tooth on the actinal surface pulling pulling of body head, the interchangeable mouth of pulling of band tooth is housed on the groove that the Xiao Zui portion of chewing opens, to pull actinal surface angled with pulling the body head for it, and can install around when being subjected to torsion at the bearing pin of chewing for a short time and rotate, thereby sting tight tube members, uses as pipe wrench.

The utility model is owing to drive cannelure pulling the body shank, be equipped with in the groove and be with big helical pitch helicla flute screw rod and the female engagement of flat filament, lead-screw rotates and drives the bearing pin handle that the flat filament mother slides up and down, can limit by the digital groove that cannelure covers, can be by plane contact pinning in addition chewing for a short time of pulling that the body head is free to slide, the tooth that ends the dependence upon original short worm screw and chew is for a short time adjusted and self-marketing, thereby has just realized actual effect fast and accurately.

Because of having opened tooth on the actinal surface pulling pulling of body head, the interchangeable mouth of pulling of band tooth is equipped with in the portion of chewing for a short time again, and this improvement is simple in structure, and is easily manufactured, realized the function of use that tube members is removed stage makeup and costume again.

Be that to change the circular hole of pulling body shank tail end be plum blossom hole again, realized the effect of double offset ring spanner again.Thereby it is the high-effect spanner that a tool is used more.

The concrete structure of utility model is provided by following enforcement and accompanying drawing thereof.

Fig. 1 is the cutaway view of the high-efficiency multi-use spanner that the utility model proposes.

Describe the detail and the working condition of the utility model spanner in detail below in conjunction with Fig. 1:

This spanner comprises that is pulled a body (1), be equipped with one at its head and chew (14) for a short time, have groove (16) and symmetrical channels (11) chewing for a short time, bearing pin (15) by groove (16) will have tooth (19) and rotary interchangeable pull mouthful (18) link to each other with chewing for a short time, interchangeable pulling has groove (17) on the mouth, keep shown position under the effect of spring (22), (23).Symmetrical channels (11) goes up skewer bearing pin (12), it can slide in the hole of pulling the body head (24), have groove (13) and (20) on the bearing pin (12), for a short time chew the bottom one plane (26) is arranged, it becomes 5 ° to 15 ° angles with the hole of pulling the body head (24), pull the body head have tooth (21) pull actinal surface with interchangeable pull that mouth has a tooth (19) pull that actinal surface is not parallel to become 20 ° of angles.Have cannelure (28) pulling the body shank, the screw rod (9) with big helical pitch helicla flute (7) is housed on the bearing in groove (3) and (8), flat filament mother (10) and its engagement are arranged.It is fixing with handle (6) by the lid (2) that long through groove (4) are arranged above the cannelure that skewer is gone into the bearing pin (5) of big helical pitch helicla flute (7), the groove (27) that the band numeral is arranged on the lid (2), when driving handle (6), there is big helical pitch spiral fluted screw rod (9) under the effect of bearing pin (5), to rotate, can in cannelure (28), slides with the flat filament mother (10) of its engagement.The female upper surface of flat filament (25) can contact with the plane of chewing for a short time (26) that is free to slide, thereby chews for a short time by the female pinning of flat filament, and its position is limited by the groove (27) that handle (6) is in above the lid (2).So, as long as driving handle (6) just can limit the wrench opening size rapidly, exactly to required groove.

Because pulling pulling of body head has tooth (21) on the face, the interchangeable mouth of chewing for a short time of pulling has tooth (19), and when the clamping pipe fitting was subjected to torsion, interchangeable pull mouthful (18) can be rotated from the trend pipe fitting, and it is stung tightly, realize the operation to pipe fitting.

Pull body shank tail end and have plum blossom hole (29), can operate, realize the function of double offset ring spanner bolt, the nut of corresponding size.
