Abstract
The invention relates to a bidirectional powerful socket combination wrench. The combination wrench belongs to the socket wrench and is composed of a nut socket and a trigger, wherein the nut socket is tubular; the inner opening of the tubular front end is a nut die orifice, rectangular teeth are arranged on the circumference of the back section, and the tail end is provided with a cylindrical plug integrated with the socket; the lower end of the trigger is integrated with the lantern ring of the plug; a wing ratchet button is arranged in the stem of the handle through a pin; a boss integrated with the inside of the trigger is arranged on the ratchet button; and the bottom edge of the boss is provided with an embedded spring top bead, and the spring top bead is against the back of the wing ratchet button. The bidirectional powerful socket combination wrench is a novel and original powerful combination wrench; the combination wrench has novel design and reasonable structure; a pawl is clamped and embedded in a ratchet wheel, thus the nut can be fastened continuously and fast; and if another pawl is clamped and embedded in the ratchet wheel and rotates in the reverse direction, the nut can be unfastened, the time and labor can be saved and the working efficiency can be high.
Description
Technical field
The invention belongs to telescopic spanner, be specifically related to a kind of two-way powerful sleeve combination wrench.
Background technology
Box spanner is the elasticity bolt instrument of using always, but traditional telescopic combination wrench has the hexagon trepanning on it, and the outside, sleeve upper end is the hexagonal column cap, and during use, the borehole jack of sleeve lower end is lived nut, then the operation of degree of tightness nut.But this spanner has, and intensity is low, the sleeve arm thin, be difficult for the stressed shortcoming such as little of the application of force, trigger piece, be not suitable for the holding screw in large-scale plant, particularly its screw and equipment room distance is little and do not change all the year round in the wellhead equipment of rod-pumped well, because of the corrosion of exposing to the weather, during maintain and replace, the deficiency of existing spanner promptly highlights.
Summary of the invention
The present invention is intended to overcome the deficiencies in the prior art, does further transformation on the basis of traditional telescopic combination wrench, provides a kind of and has been primarily aimed in the two-way powerful sleeve combination wrench of the assembly and disassembly of large-scale screw.
Two-way powerful sleeve combination wrench of the present invention is to be made of screw cap sleeve and trigger piece.Screw cap sleeve is a tubular, the internal orifice of tubular front end be nut die orifice, back segment ring week arrange rectangular teeth, tail end has with sleeve is connected the cylindrical plug of one.Have in the plug collar that the lower end of trigger piece fuses, the handle bar by bearing pin to cooperate the aerofoil profile sour jujube key of installing, have on the sour jujube key and the inboard all-in-one-piece boss of trigger piece, spring top bead is butted on the back of aerofoil profile sour jujube key along embedded spring top bead is arranged at the end of boss.
As a further improvement on the present invention, what connect at the tail end of screw cap sleeve is the cylindrical plug of undergauge, is embedded with the retainer spring pearl of projection on the cylinder of cylindrical plug.
As a further improvement on the present invention, the ring week groove that matches with the retainer spring pearl is arranged on the inwall of the plug collar.
As a further improvement on the present invention, the alternate crack with the plug collar of cylindrical plug cooperates.
As a further improvement on the present invention, described wing sour jujube key is to be the downward symmetrical ratchet in summit, two ends with the axis.
As a further improvement on the present invention, the back segment of screw cap sleeve is the ratchet of rectangular teeth.
Two-way powerful sleeve combination wrench of the present invention is a kind of powerful combined type spanner of novel original creation, its modern design, rational in infrastructure, and a ratchet inlay card is at ratchet, just can be continuously, quick fastening nut; As with another ratchet inlay card on ratchet, counter-rotating, the effect, time saving and energy saving that can realize unloading nut, high efficiency.
Description of drawings
Figure of description is the structural representation of two-way powerful sleeve combination wrench of the present invention.
The specific embodiment
Two-way powerful sleeve combination wrench of the present invention is to be made of screw cap sleeve 1 and trigger piece 2, and screw cap sleeve 1 is a tubular, the internal orifice of tubular front end be nut die orifice 3, back segment ring week arrange rectangular teeth 4, tail end has with sleeve 1 is connected the cylindrical plug 5 of one; What the lower end of trigger piece 2 fused is the plug collar 6, and cylindrical plug 5 and the plug collar 6 be matched in clearance mutually.Have in the trigger piece 2 handle bars by bearing pin to cooperate the aerofoil profile sour jujube key of installing 7, wing sour jujube key 7 is to be that summit, two ends have downward symmetrical ratchet with the axis.Have on sour jujube key 7 and trigger piece 2 inboard all-in-one-piece boss 8, spring top bead 9 is butted on the back of aerofoil profile sour jujube key 7 along embedded spring top bead 9 is arranged at the end of boss 8.
The cylindrical plug 5 of the undergauge that the tail end of screw cap sleeve 1 connects inserts in the plug collar 6, the retainer spring pearl 10 that is embedded with projection on the cylinder of cylindrical plug 5 is stuck in ring week on the inwall of the plug collar 6 on the groove 11, and then undergauge plug 5 is fixed with the plug collar 6 connect, and then regulate the ratchet at wing sour jujube key 7 two ends, the intensity when making it inlay card and coming 1 work of stiffnut sleeve in the ratchet place of the rectangular teeth 4 of screw cap sleeve 1 back segment.After screw cap sleeve 1 assembles with the plug collar 6, the nut die orifice 3 of screw cap sleeve 1 internal orifice is enclosed within the outside of large-scale nut,, under the active force of trigger piece 2, can strong screw be disassembled or be fixed on the assigned address then to trigger piece 2 application of forces.
