Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

Referring to fig. 1-2, a novel excavator oil cylinder nut wrench comprises an upper clamp 4 and a lower clamp 6, wherein the length and width of the upper clamp 4 and the lower clamp 6 are consistent, the top of the upper clamp 4 is of an arch structure, clamping grooves 5 are formed in the central line of the lower surface of the upper clamp 4 and the central line of the upper surface of the lower clamp 6, meshing tooth grooves 13 are formed in the inner surfaces of the clamping grooves 5, the device is meshed with an oil cylinder nut more tightly through the meshing tooth grooves 13, the phenomenon of slipping is not prone to occur during rotation, the clamping grooves 5 are of a V-shaped structure, two ends of the upper clamp 4 and two ends of the lower clamp 6 are connected through connecting bolts 3, the two connecting bolts 3 are arranged, the two connecting bolts 3 are symmetrical to each other about the vertical central line of the upper clamp 4, the connecting bolts 3 penetrate through the upper clamp 4 and the lower clamp 6, one end of each connecting bolt 3 is sleeved with a clamping nut 1, a gasket 2 is sleeved between the clamping nut 1 and the lower clamp, 6 bottom centers of lower clamp body department is provided with the main handle 8, slot 7 has been seted up to main handle 8 inside, the inside grafting of slot 7 has with extension handle 10, the one end of extension handle 10 is provided with handle ring 11, it has positioning bolt 9 to peg graft above the main handle 8, such structure setting makes whole handle portion form by main handle 8 and the combination of extension handle 10, and extension handle 10 can slide inside slot 7, positioning bolt 9 is used for fixing a position to extension handle 10, when extension handle 10 slides inside slot 7, the effective length of whole handle portion changes, thereby make the arm of force adjustable of this spanner, thereby make the device's application scope wider, it is more laborsaving to use.

Go up clamp 4 lower surface and 6 upper surface both ends departments of lower clamp and all be provided with counterpoint groove 12, and go up clamp 4 and the 12 tenon fourth of the twelve earthly branches block connections in the counterpoint groove on the clamp 6 down, such structure setting makes the clamp 4 inseparabler after connecting with lower clamp 6, and the phenomenon of dislocation can not appear, and the clamp 4 forms a clamping structure with the combination of 5 in the card slot on the clamp 6 down on the clamp 4 in the convenience.

The working principle of the device is that referring to fig. 1-2, when the device is used, the connecting bolt 3 is firstly rotated according to the size of an oil cylinder nut of an excavator, so that the distance between the upper clamp body 4 and the lower clamp body 6 is changed until the clamping grooves 5 on the upper clamp body 4 and the lower clamp body 6 can be just clamped on the oil cylinder nut of the excavator, then the length of the handle part is adjusted according to the environment at the position of the oil cylinder nut of the excavator, the specific adjusting method is that the lengthened handle 10 is firstly pulled, so that the effective lengths of the lengthened handle 10 and the main handle 8 can just match the environment at the position of the oil cylinder nut of the excavator, then the lengthened handle 10 is positioned through the positioning bolt 9, the adjustment of the device is completed, then the oil cylinder nut of the excavator is sleeved into the clamping grooves 5 between the upper clamp body 4 and the.
