Description

The extended type inner hexagon spanner of hexagonal countersunk head in band

Technical field

The utility model belongs to spanner technical field, especially relates to a kind of extended type inner hexagon spanner with interior hexagonal countersunk head.

Background technology

Vibration mechine is due to the restriction of stage body size, and mesa diameter size is generally all less than 400 millimeters.Auto parts and components product usually all can much larger than mesa dimensions, and for meeting large scale parts product vibration requirement, testing stand producer has on original table top, install an expanding table top additional.For making the expanding table top installed additional drop to minimum on the impact that product vibrates, expanding table top size can only be amplified by trapezoidal shape gradually, and for meeting the requirements of up-sizing, table top will increase 200 millimeter substantially.During fixing expanding table top, need, with the trapezoidal extended range of extended type inner hexagon spanner through 200 millimeters, then just can tighten the hexagon socket head cap screw between expanding table top and vibration table.Due to the sleeve outer diameter of conventional band extension arm inner hexagon spanner, more than one times of the own size of inner hexagon spanner often, and vibrate expanding table top for improving intensity, middle bore size requires to do the smaller the better, thus proposes requirement to the length of inner hexagon spanner.Need to screw 16 hexagon socket head cap screws when fixing vibration table and expanding table top, and the T-shaped inner hexagon spanner of existing lengthening one can only enclose manual rotation, not only consuming time but also effort, global design is reasonable not enough.

In order to improve prior art, people have carried out long-term exploration, propose various solution.Such as, Chinese patent literature CN02222315.0 discloses a kind of T-shaped inner hexagon spanner, is formed by connecting, it is characterized in that by hexagon bar: in long-armed one end and long-armedly symmetrically, be vertically connected with left galianconism and right galianconism.

Although such scheme to some extent solves the deficiencies in the prior art, when fixing vibration table and expanding table top, the T-shaped inner hexagon spanner of existing lengthening one can only enclose manual rotation, not only consuming time but also effort, and global design is reasonable not enough.

Utility model content

The purpose of this utility model is for the problems referred to above, and provide a kind of reasonable in design, structure is simple, the extended type inner hexagon spanner of hexagonal countersunk head in time saving and energy saving band.

For achieving the above object, the utility model have employed following technical proposal: the extended type inner hexagon spanner of hexagonal countersunk head in band, comprise wrench body, one end of described wrench body is provided with interior hexagonal spanner, the other end of wrench body is provided with interior hexagonal countersunk head, the upper surface of described interior hexagonal countersunk head has inner hexagonal hole, T-shaped spiral arm is socketed with outside described wrench body, described T-shaped spiral arm comprises spiral arm bar, the both sides of described spiral arm bar are respectively equipped with sidespin arm, the mounting groove coaxial with sidespin arm is had in described sidespin arm, on described sidespin arm, cover has flexible protective casing.Interior hexagonal countersunk head can connect electronic or pneumatic tool, and directly this inner hexagon spanner of rotation pre-fixes the hexagon socket head cap screw outside long distance, and then screws with T-shaped spiral arm reinforcing; Also can the direct screwing bolts of retrofitting torsion spanner, after overcoming the long distance in interval, the drawback that hexagon socket head cap screw can only screw with manual wrench from coil to coil, substantially increases operating efficiency, has with low cost, easy to use, long-lived beneficial effect simultaneously.

In above-mentioned band hexagonal countersunk head extended type inner hexagon spanner in: described T-shaped spiral arm and wrench body integrally manufactured.

Alternatively, in above-mentioned band hexagonal countersunk head extended type inner hexagon spanner in: described T-shaped spiral arm and wrench body are split manufacture, can change the wrench body of different size as required.

Compared with prior art, in this band, the advantage of the extended type inner hexagon spanner of hexagonal countersunk head is:

The first, interior hexagonal countersunk head can connect electronic or pneumatic tool, and directly this inner hexagon spanner of rotation pre-fixes the hexagon socket head cap screw outside long distance, and then screws with T-shaped spiral arm reinforcing; Also can the direct screwing bolts of retrofitting torsion spanner, after overcoming the long distance in interval, the drawback that hexagon socket head cap screw can only screw with manual wrench from coil to coil, substantially increases operating efficiency, with low cost, easy to use, durable in use.
