Embodiment
Below in conjunction with drawings and Examples, the utility model is described further.
As shown in Figure 1, hand-operated folding type ice auger, includes rocking handle 1 and drilling rod 2, and drilling rod 2 bottoms are provided with bores cutter 3, and drilling rod wall is provided with helical form ice guiding vane 4.
As shown in Figure 1, as current modal a kind of jackrod structure, drilling rod 2, with axially inserting cavity 5, is provided with a positioning spiro pit 6 radially connecting on the outer wall at cavity top, be provided with a core bar 7 at cavity inside, on core bar 7, have spaced multiple locating hole 8 vertically.As shown in accompanying drawing 3, accompanying drawing 4, when drilling rod 2 and core bar 7 insert in the insertion cavity of drilling rod 2, bolt 9 its bar portions are fixed on core bar 7 on drilling rod 2 through the locating hole 8 on described positioning spiro pit 6 and core bar, and core bar 7 stretches out the body of rod on drilling rod 2 tops as the extension bar 11 being connected with rocking handle horizontal ends 10.
As shown in Figure 2, the end of rocking handle horizontal ends 10 is provided with a groove caving inward 12, is provided with a threaded rod 13 that stretches out groove at groove 12 center.In the present embodiment, extension bar 11 is cylindrical shaft structure, and corresponding recesses 12 is arcuation groove, and arcuation groove 12 radiuses are consistent with cylindrical bar radius.As shown in accompanying drawing 1, accompanying drawing 3 and accompanying drawing 4, near being provided with a through hole 14 radially on the body of rod of extension bar 11 afterbodys, when the extension bar part body of rod after the through hole 14 that threaded rod 13 passes on extension bar 11 is positioned at, groove 12 and the extension bar body of rod and groove inner surface are seamless to coincide, and is provided with locking nut 15 at threaded rod external part.
As shown in Figure 3, realizing rocking handle 1 by locking nut 15 is connected with the firm of drilling rod 2, the body of rod of extension bar 11 is subject to the restriction of groove 12 cell walls simultaneously, forces the rotation of drilling rod 2 to overlap with the rotation of rocking handle 1, thereby rotates by the drilling rod 2 that rotarily drives of rocking handle 1.
Known by foregoing description, in the time of folding rocking handle 1, unclamp the locking nut 15 shown in accompanying drawing 3 rocking handle 1 is pulled out, make extension bar 11 depart from groove 12.180 ° of rotation rocking handles 1; rocking handle 1 is folding downwards; now again rocking handle is promoted to drilling rod 2 directions; extension bar 11 enters that groove 12 on rocking handle horizontal ends end face is interior realizes seamless coincideing again; locking nut 15 is locked; realize the strong bonded of rocking handle 1 and drilling rod 2, configuration state now as shown in Figure 4.When needs separate rocking handle 1 with drilling rod 2, only locking nut thoroughly need be backed out, outwards extract rocking handle.
According to the description of the present embodiment, in reality is manufactured, the shape of extension bar 11 can adopt various ways, if extension bar 11 is rectangular block structure, now the groove 12 on rocking handle horizontal ends end face is set to rectangular channel, the width of rectangular channel is consistent with the width of extension bar, and the part body of rod of extension bar can enter equally in groove and realize seamless coincideing with groove surfaces, reaches above-mentioned functions.
For another example, the shape of extension bar 11 adopts tri-prismoid form, and groove is driveed as cross section is leg-of-mutton groove, and the part body of rod of extension bar also can enter in groove and realize seamless coincideing with groove surfaces, reaches above-mentioned functions.
Therefore, the groove shapes on rocking handle horizontal ends end face is offered according to the shape of extension bar, can realize above-mentioned functions as long as the extension bar part body of rod can enter in groove and with seamless the coincideing of groove inner surface.
In the present embodiment, drilling rod 2, with core bar 7, can be adjusted the length of drilling rod by the extension elongation of adjusting core bar 7, utilizes the part body of rod of core bar 7 afterbodys to be connected with rocking handle as extension bar 11.If in manufacturing actual, drilling rod is regular length structure, and drilling rod, without inserting chamber, now directly utilizes the part body of rod of drilling rod afterbody to use as extension bar, offers radially through hole on the body of rod of drilling rod afterbody.
