Abstract
The utility model relates to a spanner clamping seat. An extended convex column is arranged on three symmetrical inner corners of a sleeve barrel or a spanner hole of a ring spanner respectively in a vertical and equally high way to form the clamping seat. The utility model overcomes the phenomenon that when screw caps and screw bolts are screwed down or loosened, an operator is in the state of force application all the time to prevent the disengagement of the spanner. Therefore, the utility model has the advantages of convenient use, high work efficiency, simple structure and convenient production and manufacture.
Description
The utility model relates to the clamping hole seat of a kind of spanner grip slipper, particularly sleeve or double offset ring spanner.
The clamping hole seat of existing known box spanner or double offset ring spanner, retaining part all relate to and become to run through the mode of being inserted in.Nut formula bolt head screws or when unclamping work, operator's hand must be in application of force state all the time so being inserted in.Careless slightly or the application of force is rotated excessively as the application of force, all can cause the clamping hole seat to break away from the nut and bolt phenomenon.Thereby cause low, the unhandy defective of work operations efficient.Thereby people adorn a flexible steel ball with the spring pushing and pressing and overcome this phenomenon on driving hole seat top, but this structure is single-point contact wearing and tearing easily, and can produce phenomenon in the steel ball retraction hole when strength is excessive, and ineffective, as shown in Figure 3 structure.Another kind is to adorn a control anticreep catch that can move forward and backward on the clamping hole seat, and this structure exists when during greater than driving hole thickness, promptly being produced the weak point that can't use, as shown in Figure 4 by the nut of turn or bolt head pitch.
The purpose of this utility model is to propose a kind of spanner grip slipper, is shaped on the cylinder that several symmetries are vertically stretched out in its hexagon clamping hole, the weak point that spanner and nut, bolt head easily break away from when avoiding operating.
The utility model is realized in the following way, in the hex wrench aperture, three symmetrical interior angle places of peritreme bottom, be shaped on vertical, contour, stretch out isometric cylinder respectively, cylinder length is the inscribed circle that the cylinder top constitutes, this circle greater than revolving bolt outer through or nut at the bottom of directly.
The advantage that the utlity model has is: easy for operation, because the cylinder in the driving hole abuts against on nut, overcome in the past that the operator must be in application of force state always, and the weak point of having avoided spanner to break away from has improved operating efficiency.Advantage was more outstanding when particularly screw-in unclamped than long threaded rod, and it is simple in structure, be easy to manufacture.
Description of drawings:
Accompanying drawing 1, the utility model stereogram
Accompanying drawing 2, the utility model work cutaway view
Accompanying drawing 3, existing flexible ball type spanner grip slipper figure
Accompanying drawing 4, existing blocked flake type spanner grip slipper figure
, be described in further detail in conjunction with the accompanying drawings to a kind of spanner grip slipper of the utility model below by embodiment:
At accompanying drawing 1 middle sleeve formula double offset ring spanner, in the hex wrench hole, termination 12 of wrench body 11, bottom three symmetrical interior angles place at bore edges, be shaped on vertical contour cylindrical hole 13, adopt the interference fits embedding to press long cylinder 20 such as in each hole, garden respectively, footpath at the bottom of the cylinder extension elongation should keep behind the setting-in inscribe garden diameter that 3 column top constitute greater than revolving major diameter of thread or nut.Its operation principle as shown in Figure 2, after driving hole 12 was inserted in nut, cylinder 20 abutted against on nut top in the hole, makes wrench body 11 can not break away from nut.
Claims (1)
- A kind of spanner grip slipper, it is characterized in that: in hex wrench hole (12) mouth, that three symmetrical interior angle places of peritreme bottom are shaped on is vertical, contour, stretch out isometric cylinder (20) respectively, cylinder length is the inscribe garden that cylinder (20) top constitutes, this garden greater than institute's rotary screw outer through or nut at the bottom of the footpath.
