Abstract
The utility model discloses a novel sealed adjustable spanner, which belongs to the mechanical industry field. The utility model is mainly characterized in that the sealed adjustable spanner not only has the adjustability of an adjustable spanner but also has the reliability of a non-adjustable wrench. The die cavity of the spanner body is sealed; the adjusting screw of the spanner body moves lengthways and flatly, which has little occupied space of the spanner and material saving. The main purpose of the sealed adjustable spanner is the same to the purpose of the various original spanners. The utility model is suitable for fastening screws of various specifications.
Description
Closed monkey wrench is the spanner that a kind of the turn of the screw of novelty is used, and belongs to mechanical industry field.
Existing spanner can be divided into monkey wrench and back-up wrench two classes substantially, and its pluses and minuses are respectively arranged, the back-up wrench the turn of the screw is reliable, volume is little, in light weight, to take the spanner space little, is its advantage; Shortcoming is non-adjustable, can only adapt to screws a certain or two kinds of specifications.Monkey wrench is adjustable, and the screw that can adapt to multiple different size is its advantage; Shortcoming is in the process of tighten the screws, skids sometimes, and unsafe factor is arranged, and volume, weight, to occupy the space big than back-up wrench.
The present invention " has got its length, has kept away its weak point " and designed after having considered the various pluses and minuses of existing spanner.
The present invention is by wrench body (1), adjusting screw(rod) (2), and pressing plate (3), screw (4), (5) five parts of adjusting nut are formed.
Explain invention below in conjunction with Figure of description.
With reference to accompanying drawing: the anterior die cavity of wrench body (1) seals, the front portion of adjusting screw(rod) (2) is a cuboid, work to hold out against bolt, the rear portion be on one end mill the screw rod on one plane, pressing plate (3) is fixed on the wrench body (1) by screw (4), its role is: 1, the restriction adjusting screw(rod) does not break away from wrench body, and 2, make that adjusting screw(rod) can only translation, can not rotate.
During use, rotation adjusting nut (5), vertically translation of adjusting screw(rod) (2), screw can be tightened or unscrew to its first half puller bolt just.
Compare with existing technology, the present invention has following advantage:
1, the adjustability that had both had monkey wrench has the reliability of back-up wrench again.
2 compare with existing spanner, economize with material, and in light weight, it is little to take the spanner space.The present invention all can make in general medium and small machinery plant or tools factory.
Claims (4)
1, a kind of closed monkey wrench comprises wrench body (1), adjusting screw(rod) (2), pressing plate (3), screw (4), adjusting nut (5), and it is characterized in that: the anterior die cavity of wrench body (1) seals, vertically translation of adjusting screw(rod) (2).
2, closed monkey wrench according to claim 1 is characterized in that: the front portion of adjusting screw(rod) (2) is a cuboid, is milled with a plane above the latter half of screw rod.
3, closed monkey wrench according to claim 1 is characterized in that: wrench body (1) is gone up and is fixed with a pressing plate (3) by screw (4).
