Abstract
The utility model discloses general bolt pre-tightening tool, which comprises a hexagonal matching section, and is characterized in that: a hexagonal inner hexagon bolt wrench is fixedly arranged at at least one end of the matching section; a hexagonal blind hole is formed in each inner hexagon bolt wrench, and can be taken as an outer hexagon bolt wrench; preferably, hexagonal inner hexagon bolt wrenches are fixedly arranged at the two ends of the matching section; and the radial sizes of the two inner hexagon bolt wrenches and the hexagonal blind holes are different. The general bolt pre-tightening tool can be suitable for bolts of multiple models, so that the cost is lower.
Description
Technical field
The utility model relates to a kind of bolt pretension frock.
Background technology
Hydraulic jack is when the assembling gland, because of hydraulic jack not of uniform size, the specification that bolt uses is more, and the bolt pretension frock of using at present, no matter be the hexagon socket head cap screw spanner, or outer-hexagonal bolt spanner, all can only be applicable to a kind of model, therefore every kind of bolt need design a kind of frock, causes cost higher.
The utility model content
The purpose of this utility model is at the prior art above shortcomings, and a kind of ordinary bolt pretension frock is provided, and it can be applicable to the bolt of multiple model, so cost is lower.
For achieving the above object, ordinary bolt pretension frock of the present utility model, the cooperation section that comprises six prismatics, it is characterized in that being installed with the hexagon socket head cap screw spanner of six prismatics at least one end that cooperates section, also be provided with the blind hole of six prismatics in each hexagon socket head cap screw spanner, the blind hole of six prismatics can be used as outer-hexagonal bolt spanner and uses.
As preferably, the described two ends that cooperate section all are installed with the hexagon socket head cap screw spanner of six prismatics, and the radial dimension of two hexagon socket head cap screw spanners and six prismatic blind holes is all inequality.
The utility model clamps the cooperation section of six prismatics by spanner, according to the model of bolt, can select the blind hole of suitable hexagon socket head cap screw spanner or six prismatics, can lock or unclamp bolt; Because the utility model can be applicable to the bolt of multiple model, so cost is lower.
