Technical field
The utility model relates to a kind of spanner, relates in particular to a kind of telescopic handle spanner.
Background technology
In machining, production, assembling, maintenance field, spanner is a kind of conventional instrument, and adjustable wrench is modal spanner, and it is mainly used in screwing or becomes flexible thumb screw or nut, electrician commonly uses 200,250, tri-kinds of 300mm, during use according to the size apolegamy of nut.
Adjustable wrench is generally pulled lip by staying, the active lip, worm gear, handle pulled forms, and during use, right hand handle, after hand more leans on, pulls more laborsavingly, while pulling primary nut, need to rotate worm gear, regulates the size of pulling mouthful, to adapt to the size of nut.
In industrial electrical network, many power equipments are arranged on high-altitude conventionally, use adjustable wrench to twist and change a lower angle, have both lost time also can bring the inconvenience in use, and because the length of spanner is fixed, in using and carrying, also there is certain inconvenience.
Utility model content
The technical problems to be solved in the utility model is just: the problems referred to above that exist for prior art, the utility model provides a kind of telescopic spanner simple in structure, and the decreased food capable of regulating of this spanner is easy to use and carry, and handle two ends arrange different clamping devices, highly versatile.
For achieving the above object, telescopic spanner of the present utility model, comprise handle, be fixed on pulling lip, being fixed on the pullover of the handle other end of handle one end, above-mentionedly be provided with regular polygon running-on in pullover, above-mentioned handle comprises hollow sleeve, set bolt and is positioned at the connecting rod of sleeve, on above-mentioned sleeve, be provided with locating hole, on above-mentioned connecting rod, be provided with at least 3 through holes that equidistantly distribute, above-mentioned set bolt is connected in locating hole and one of them through hole, above-mentioned pulling on the sleeve that lip is fixed on handle.In this programme, can change the position of connecting rod in sleeve by adjusting the through hole being connected with set bolt, realize the flexible of handle, thereby change the length of handle; In addition, the spanner one end in this programme is for pulling lip, and the other end is conventional pullover of box spanner, applicable different types of bolt, screw, workpiece etc., easy to use, highly versatile.
For making the pullover use of above-mentioned telescopic spanner more convenient, further, this telescopic spanner also comprises for connecting handle and pullover elbow.
Because present most of bolt and screw are hexagonal structure, be to coordinate with it better, as preferably, above-mentioned running-on be shaped as regular hexagon.
Further, the above-mentioned lip of pulling comprises staying and pulls lip, lives and to pull lip and to pull the worm gear that lip is connected with living, above-mentioned stay to pull on lip be provided with non-return nail, non-return nail is positioned at worm gear one side.This non-return nail can avoid worm gear to pull lip and move to change and pull a mouthful yardstick adjusting again to rotate after pulling mouthful yardstick and drive to live.This non-return nail can also rotate staying to pull on lip.
For strengthening the intensity of this telescopic spanner, as preferably, above-mentioned handle, pull lip, the pullover nickel-chrome alloy steel that is Cr15Ni60 by chrome alum steel alloy or the trade mark forms.
With respect to prior art, the utlity model has following advantage and beneficial effect:
1, pinch bar of the present utility model is scalable, carries with easy to use;
2, spanner of the present utility model one end is for pulling lip, and the other end is pullover, easy to use, the highly versatile that box spanner is conventional;
3, between pullover and handle of the present utility model, adopt elbow to be connected, use more laborsaving and convenient;
4, the utility model is simple and compact for structure, cost is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Marginal data: 1, handle; 11, sleeve; 111, locating hole; 12, connecting rod; 121, through hole; 13, set bolt; 2, pull lip; 21, stay and pull lip; 22, live and pull lip; 23, worm gear; 24, non-return nail; 3, pullover; 31, running-on; 4, elbow.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but embodiment of the present utility model is not limited only to this.
[embodiment 1]
As shown in Figure 1, the telescopic spanner of the present embodiment, comprises handle 1, pulls lip 2, pullover 3, wherein, pulls lip 2 and pullover 3 and is separately fixed at handle 1 two ends.In above-mentioned pullover 3, be provided with regular polygon running-on 31; Above-mentioned handle 1 comprises hollow sleeve 11, set bolt 13 and is positioned at the connecting rod 12 of sleeve 11, wherein, on sleeve 11, be provided with locating hole 111, be provided with at least 3 through holes 121 that equidistantly distribute on connecting rod 12, set bolt 13 is connected in locating hole 111 and one of them through hole 121.Above-mentioned sleeve 11 is away from one end sealing of connecting rod 12, and with pull lip 2 and be fixedly connected with.In the present embodiment, fixing better for making to pull lip 2 and sleeve 11, do not affect use, pull the mode of lip 2 and sleeve 11 employing one cast moldings, in practical application, also preferably adopt which, but for the ease of assembling and carrying, also can adopt both to produce separately the mode that then assembling is fixed together.In the present embodiment, can realize the flexible of handle 1 by adjusting through hole 121 positions of change connecting rod 12 in sleeve 11 that are connected with set bolt 13, thereby change the length of handle 1, spanner is used and carry more convenient; In addition, the spanner one end in this programme is for pulling, and 2, the other end is conventional pullover 3 of box spanner, applicable different types of bolt, screw, workpiece etc., easy to use, highly versatile.
