Abstract
The utility model discloses a kind of movable valve copper cover three-jaw spanner, comprise handle, handle connects a spanner seat, and spanner seat edge level stretches out three telescopic claws, and telescopic claw is uniformly distributed along spanner seat edge, and angle is between any two 120 °; Every bar telescopic claw is strip, and central authorities are provided with a guide rail, and guide rail extended line is through spanner seat center, and guide rail is provided with can along the fixture block of slide, and fixture block is fixed on guide rail by locknut.The beneficial effects of the utility model are, can regulate the size of three-jaw along guide rail, are applicable to the valve copper cover maintenance of different size.
Description
Technical field
The utility model relates to a kind of hardware & tools, especially a kind of spanner.
Background technology
As shown in Figure 1, its upper surface is rounded face to the structure of valve copper cover 7, equidistantly on same periphery is distributed with the identical fan-shaped draw-in groove 8 of 3 shapes.Use three-jaw as specific purpose tool when removing valve copper cover during valve maintenance, with three-jaw mating valve copper sheathing three-jaw, valve copper cover is spun out.Former three-jaw is fixed dimension, and valve copper cover size differs, and required three-jaw size is also different, brings inconvenience to maintenance.
Utility model content
The utility model object is, overcomes the defect of prior art, proposes a kind of movable valve copper cover three-jaw spanner.
The technical solution adopted in the utility model is as follows:
Movable valve copper cover three-jaw spanner, comprise handle, handle connects a spanner seat, and spanner seat edge level stretches out three telescopic claws, and telescopic claw is uniformly distributed along spanner seat edge, and angle is between any two 120 °; Every bar telescopic claw is strip, and central authorities are provided with a guide rail, and guide rail extended line is through spanner seat center, and guide rail is provided with can along the fixture block of slide, and fixture block is fixed on guide rail by locknut.
The beneficial effects of the utility model are, can regulate the size of three-jaw along guide rail, are applicable to the valve copper cover maintenance of different size.
Accompanying drawing explanation
Fig. 1 is the structural representation of valve copper cover.
Fig. 2 is the structural representation of spanner.
Detailed description of the invention
In order to more clearly state the utility model, below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 2, movable valve copper cover three-jaw spanner, comprises handle 1, handle connects a spanner seat 2, and spanner seat is regular hexagon, on three mutual non-conterminous limits of spanner seat, edge level stretches out three telescopic claws 3, and telescopic claw is uniformly distributed along spanner seat edge, and angle is between any two 120 °; Every bar telescopic claw is strip, and central authorities are provided with a guide rail 4, and guide rail extended line is through spanner seat center, and guide rail is provided with can along the fixture block 5 of slide, and fixture block is fixed on guide rail by locknut 6.During use, according to the size of valve copper cover diameter, regulate the position of fixture block on guide rail, match.Then, tighten locknut, spanner is entangled copper sheathing, fixture block embeds in the draw-in groove of copper sheathing upper surface, holds handle and is spun out by valve copper cover.
Be only specific embodiment of the utility model above, but the utility model is not limited thereto, the changes that any person skilled in the art can think of all should fall into protection domain of the present utility model.
