Abstract
The utility model discloses a fast adjustable spanner which is a tool for screwing hexagon nuts or screw bolts, mainly comprising a spanner handle with arc flanges and a socket spanner provided with hexagon holes and hinged in the spanner handle. The fast adjustable spanner has self-adjustable ability by the matching of the hexagon holes and the arc flanges, so the utility model is used for screwing nuts with various sizes.
Description
The utility model relates to a kind of spanner that is used for twisting hex nut or bolt, particularly relates to a kind of just need not the adjusting and can twist the nut of all sizes or the spanner of bolt.
Existing spanner mainly contains two kinds: i.e. the double offset ring spanner of hexagon ring and adjustable spanner, and the former can not regulate, latter's bad adaptability, so people thirst for obtaining a kind of spanner of regulating voluntarily always.
The purpose of this utility model is that a kind of adaptable fast monkey spanner will be provided, and this spanner can be adjusted to voluntarily nut or bolt are turned.
The utility model is based on following principle: hex nut or bolt are regular hexagon, the difference of the nut that varies in size is hexagonal length of side difference, and six angles are that perseverance is 120 °, the Kong Bianjun that any two angles are 120 ° can match with two limits of hex nut, if can on the 3rd limit, exert pressure, just this hex nut can be tightened or unclamps on this basis.Therefore the spanner that the utility model proposed is such formation: have one that (each interior angle of this hexagon ring is 120 °) is provided with a rotating smooth flange in the hexagon ring of the different length of sides, along with flange and hexagon ring relative position change, flange is shared spatial variations in the hole, thereby the nut of different sizes is stuck in the hole.
Below in conjunction with specific embodiment and accompanying drawing thereof the utility model is described further.
Fig. 1 is the floor map according to the fast monkey spanner that the utility model proposes.
As shown in Figure 1, fast monkey spanner comprises trigger piece 1 and cage plate 2, cage plate 2 is by pin 4 and the hinge joint of plate handle, cage plate 2 is provided with hexagon ring 5, each interior angle of hexagon ring 5 is 120 °, and its length of side satisfies (c=e)＞(a=b=f)＞d, and a shortest length of side has determined the size of the minimum nut that can twist in six limits, its position from pin farthest, the length of side (from pin nearest) relative with this minor face determined the size of the maximum spiral shell thumb that can twist.The termination of plate handle 1 is provided with arc chimb 3, arc chimb 3 cooperates with hexagon ring 5, so that it is big more that the nut arc chimb of tightening effectively or unclamping various sizes enters into the part of hexagon ring, spanner is suitable for twisting little nut more, when the arc chimb did not overlap fully with hexagon ring, spanner can be twisted maximum sized nut.Only need during work nut 6 is inserted in the hexagon ring 5.By direction shown in the arrow A, pull trigger piece, trigger piece 1 rotates with respect to cage plate 2 around pin 4, corresponding therewith, the change in location of arc chimb 3 in hexagon ring 5, (shown in the arrow B) are that the part that shape chimb 3 enters in the hexagon ring 5 increases, when arc chimb 3 touches nut 6 in the hexagon ring 5, relatively rotating of 2 of trigger piece 1 and cage plates stops, and pulls trigger piece again, and nut 6 will be subjected to pull force and be tightened.
Claims (1)
- A kind of fast monkey spanner, comprise trigger piece 1, the end face that it is characterized in that trigger piece 1 is provided with arc chimb 3, corresponding with arc chimb 3, be hinged with cover at an end of trigger piece 1 by pin 4 and pull 2 with hexagon ring 5, hexagon ring 5 each interior angle are 120 °, but its every length of side satisfies (c=e)＞(a=b=f)＞d.
