Abstract
The utility model relates to an improved rotating spanner. The spanner comprises a square pipe handle, a pliers belt, a fan-shaped bracket, a screw, a knob, a pliers belt connecting piece and an axial positioning sleeve, wherein the pliers belt connecting piece is a groove piece of which the upper and lower parts are provided with wing plates; a screw hole fitted with a thread of the screw is formed in the center of the groove piece; the axial positioning sleeve has a split symmetrical structure; a through hole fitted with a journal groove of the screw is formed at the axis of the axial positioning sleeve; the screw is connected with the screw hole of the pliers belt connecting piece through the thread; the axial positioning sleeve is clamped in the journal groove of the screw; and the symmetrical structure of the axial positioning sleeve are fixed at the tail end of the handle through a screw. The spanner has the advantages that 1) direct friction between the pliers belt and a pipe orifice of the handle is avoided, so that the service life of a product is prolonged; 2) the pliers belt connecting piece is the groove piece of which the upper and lower parts are provided with the wing plates, so that the stress condition of the pliers belt connecting piece after the screw is tightened is improved, and deviation and clamping are avoided; and 3) the screw is axially positioned reliably and cannot axially move.
Description
Technical field:
The utility model relates to a kind of instrument fastening, that connect, dismantle that is used for, and especially relates to a kind of infinitely variable and is used for the modified rotary spanner that automobile filter is installed.
Background technology:
In the prior art; A kind ofly be suitable for installing the rotary spanner that automobile filter is used; Is made up of pincers band, fan, handle, the device that is fixed on the adjusting pincers band degree of tightness in the handle, its weak point is: first pincers band directly is prone to friction with the handle inlet, pincers be with and handle all easy to wear; It two is that the member of regulating pincers band degree of tightness is prone to wander off, is prone to screens, regulates pincers and drives and do dumbly, influence result of use, needs further improvement.
The utility model content:
The purpose of the utility model is the modified rotary spanner that a kind of simple in structure, easy to operate, long service life is provided to the prior art weak point.
The purpose of the utility model is to realize through following measure: a kind of modified rotary spanner, and it comprises square tube type handle, pincers band, fan, screw rod, turn-knob, it is characterized in that, also has pincers band connector, axial location cover; Said pincers band connector has the grooved spare of wing plate on being; Grooved spare center is provided with the screw with the screw flight kissing, and said axial location cover is the dissection type symmetrical structure, and place, axial location cover axle center is provided with the through hole that matches with screw rod axle journal groove; Said fan is articulated and connected at the handle front end; Pincers band connector, screw rod, axial location cover are positioned at handle tube, and pincers are with an end and handle to be articulated and connected, and the other end is connected with the wing plate of pincers band connector upside after inserting the hinge pin axle steer that is articulated and connected through fan and handle in the handle tube; Said screw rod is connected with pincers band connector screw through screw thread; The screens of axial location cover is in screw rod axle journal groove, and the symmetrical junction member of axial location cover is fixed on the handle tail end through screw or rivet respectively, and turn-knob is fixedly connected with the screw rod tail end.
Said axial location cover dissection type symmetrical structure is upper and lower two channels, and the both sides sidewall of channel is perpendicular to the screw rod axial line.
Said axial location cover dissection type symmetrical structure is upper and lower two cuboids.
Said pincers with an end and handle be articulated and connected for pincers bands with two mutually across a certain distance connecting plate be articulated and connected through hinge pin, two connecting plates are articulated and connected through hinge pin and handle again.
Compared with prior art, the modified rotary spanner that has adopted the utility model to propose has following advantage: 1) avoided the direct friction of pincers band with the handle mouth of pipe, prolonged the service life of product; 2) have the grooved spare of wing plate on pincers bands connector adopts, improved the force-bearing situation that screw rod tightens up forceps major band connector, can not wander off, screens; 3) axial location of screw rod is reliable, axial float can not take place.The utlity model has advantages such as easy to operate, long service life, can promote the use of.
Description of drawings:
Fig. 1 is the example structure sketch map that the utility model proposes.
The specific embodiment:
Below in conjunction with accompanying drawing the specific embodiment is elaborated: at an embodiment of the utility model shown in Figure 1.Among the figure, a kind of modified rotary spanner, it comprises, and square tube type handle 6, pincers are with 1, fan 2, screw rod 10, turn-knob 12, pincers band connector 9, axial location cover 11.Said pincers band connector 9 on have the grooved spare of wing plate, grooved spare center is provided with the screw with screw rod 10 screw thread kissings.Said axial location cover 11 is the dissection type symmetrical structure; Place, axial location cover axle center is provided with the through hole that matches with screw rod axle journal groove; The dissection type symmetrical structure that the utility model axial location cover 11 adopts is upper and lower two channels, and the both sides sidewall of channel is perpendicular to the screw rod axial line, and the two side is provided with the through hole that matches with screw rod axle journal groove; Corresponding therewith screw rod axle journal groove has two places, and the spacing of two place's grooves is corresponding with the spacing of channel two side.The utility model axial location cover also can adopt the split type structure of upper and lower two cuboids, and two superimposed backs of cuboid are provided with the through hole that matches with screw rod axle journal groove at its place, axle center.Said fan 2 is articulated and connected at handle 6 front ends; Pincers band connector 9, screw rod 10, axial location cover 11 are positioned at handle tube; Pincers are with 1 one ends and handle 6 to be articulated and connected; The other end inserts the hinge pin axle 3 that is articulated and connected through fan 2 and handle 6 in handle 6 pipes and turns to the back to be connected through rivet 7 with the wing plate 8 of pincers band connector 9 upsides, and said screw rod 10 is connected with pincers band connector 9 screws through screw thread, and axial location is overlapped 11 screens in screw rod 10 axle journal grooves; The symmetrical junction member of axial location cover 11 is fixed on handle 6 tail ends through screw or rivet respectively, and turn-knob 12 is fixedly connected with screw rod 10 tail ends.
Said pincers are articulated and connected with an end and handle can also take following method: pincers with 1 and two mutually across a certain distance connecting plate 5 be articulated and connected through hinge pin, two connecting plates 5 are articulated and connected through hinge pin 4 and handle 6 again.
