Abstract
The utility model discloses a double offset ring spanner which is composed of a handle (1), a spanner head (12), an upper spanner (2), and a lower spanner (11). An upper contacting surface (4) of the upper spanner (4) in the spanner head (12) is a down protruding cambered surface, while a lower contacting surface (9) of the lower spanner (11) is an up protruding cambered surface. An inner upper contacting surface (5) and an inner lower contacting surface (8) is arranged on a place near the spanner head(12) openings. The upper contacting surface (4), the inner lower contacting surface (8), the lower contacting surface (9) are connected through club dents. The angular separation between the inner upper contacting surface (5) and the inner lower contacting surface (8) is 120 degrees. The utility model overcomes the defects of the inconvenience for inserting or dismounting a screw cap (7) and the disadvantage that the screw cap (7) can be easily damaged by the prior solid spanner, and provides a solid club spanner of safety and stability which the screw cap (7) can be easily inserted and dismounted without damage to the edge, and can be applied broadly to the production and living.
Description
Technical field
The utility model relates to a kind of hand-operated tools, particularly relates to a kind of plum blossom fork spanner.
Background technology
Be extensive use of bolt or nut is fixed in various fields such as machinery, furniture, and the spanner main tool of degree of tightness nut just.The openings of sizes of fork spanner is fixed, and can only carry out degree of tightness to the nut of specific size.But it is light, small and exquisite, is easy to carry, and is widely used.Existing fork spanner as shown in Figure 1, by handle 21, on pull body 22, pull body 24 down and constitute, on the contact-making surface pulling body 22 and pull body 24 and nut 7 down be two parallel surfaces, on pull body 22 contact-making surface and under pull body 24 contact-making surfaces and be connected by cambered surface in close handle 21 1 sides.The insertion of nut 7 or taking-up are inconvenient when using fork spanner.Insert/get for the ease of nut 7, the opening developed width of existing fork spanner is bigger than the specification of corresponding nut 7, cause in the process of rotary nut 7, actual is that two seamed edges of nut 7 contact with two faces of wrench opening end, the seamed edge of damage nut 7 easily during rotary nut 7.
The utility model content
The utility model has overcome the deficiencies in the prior art, provides a kind of and makes things convenient for nut to insert and rotation, the plum blossom fork spanner that the contact-making surface of spanner and nut is many.
For solving above-mentioned technical problem, the utility model by the following technical solutions:
A kind of plum blossom fork spanner, by handle 1, spanner 12, on pull body 2, pull body 11 down and constitute.The last contact-making surface 4 of pulling body 2 in the spanner 12 is cambered surfaces of protruding downwards, and the following contact-making surface 9 of pulling body 11 down is cambered surfaces protruding upward.Opening in the spanner 12 is gone up contact-making surface 5 near in having above the side of handle, and the interior contact-making surface 5 of going up links to each other by quincunx recess 3 with last contact-making surface 4.Opening in the spanner 12 has interior contact-making surface 8 down below handle, interior contact-making surface 8 down links to each other by quincunx recess 10 with following contact-making surface 9.Interior upward contact-making surface 5 and interior angle between the contact-making surface 8 down are 120 degree, link to each other by quincunx recess 6.
Further technical scheme is opening outer 1/3 bigger than interior 2/3 of going up contact-making surface 4 and 9 formation of following contact-making surface.
Further technical scheme is that spanner 12 has two, lays respectively at the both sides of handle 1.
Further technical scheme is that the openings of sizes of two spanners 12 is inequality.
Compared with prior art, the beneficial effects of the utility model are that nut 7 is easily laborsaving when inserting or taking out the opening of fork spanner, safety and firmness during rotary nut 7, do not damage seamed edge, high efficiency, wide adaptability.
Description of drawings
Fig. 1 is the structural representation of existing fork spanner.
Fig. 2 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further elaborated.
During use, nut 7 is inserted opening of the present utility model and since opening outer 1/3 than interior 2/3 big, so can easily nut 7 be inserted opening of the present utility model.4 limits of nut 7 are respectively with last contact-making surface 4, interior contact-making surface 8 down, contact-making surface 9 contacts down.The seamed edge of nut 7 places in quincunx recess 3, quincunx recess 6, the quincunx recess 10.When rotary nut 7, upward contact-making surface 4 of the present utility model, interior contact-making surface 8 down, following contact-making surface 9 are exerted oneself to 4 limits of nut 7 simultaneously, and nut 7 is not easy to skid, steadiness is good.The seamed edge of nut 7 or place space in the quincunx recess 3, quincunx recess 6, quincunx recess 10 perhaps places outside the opening of the present utility model, does not bear active force, and seamed edge can not be damaged.Since opening outer 1/3 than interior 2/3 big, so can easily nut 7 be taken out from opening of the present utility model.
Claims (4)
1. plum blossom fork spanner, by handle (1), spanner (12), on pull body (2), pull body (11) down and constitute, it is characterized in that in the spanner (12) on pull body (2) last contact-making surface (4) be the cambered surface of protruding downwards, the following contact-making surface (9) of pulling body (11) down is a cambered surface protruding upward; Opening in the spanner (12) is gone up contact-making surface (5) near in having above the side of handle, and the interior contact-making surface (5) of going up links to each other by quincunx recess (3) with last contact-making surface (4); Opening in the spanner (12) has interior contact-making surface (8) down below handle, interior contact-making surface (8) down links to each other by quincunx recess (10) with following contact-making surface (9); Interior upward contact-making surface (5) and interior angle between the contact-making surface (8) down are 120 degree, link to each other by quincunx recess (6).
