Conveniently put forth effort, the instantaneous strength of sledgehammer percussion is very big, and very container causes injury to personnel；2nd, container causes damage impeller surface, makes
Damaged into impeller static and dynamic equilibrium；Although the 3, the instantaneous stress of impeller is big, torque is very small, screws off impeller it is desirable that more energetically
Square, rather than big power, therefore, dismounting every time are all made Herculean efforts；4th, it is typically non-using pipe wrench, fixation during fixing axle
Often loosely, and it is easily damaged key.It is the preferred approach for solving the problem to realize instantaneous larger torque.
Utility model content
In view of the above-mentioned problems, the purpose of this utility model, which is to provide one kind, can instantaneously provide larger torque, it is relatively easily real
The dismounting of existing impeller, and may apply on the shaft coupling of different-diameter.
Technical scheme is used by the utility model solves above-mentioned technical problem：
A kind of axis spanner, it is characterised in that the axis spanner includes cross and handle, and the handle welds with cross
Connect, the cross is provided with movable handgrip, and the cross includes two fixed mounts being arranged in a mutually vertical manner, the fixed mount
Both ends are equipped with movable span, are provided with fastening bolt I in the movable span, the fastening bolt I passes through movable span and movable handgrip
It is fixedly connected, the movable handgrip is provided with screw, is provided with fastening bolt II in the screw, the movable handgrip passes through fastening
Bolt II is fixedly connected with shaft coupling, and the shaft coupling is fixed on axle drive end periphery.
As preferable, the fastening bolt I and fastening bolt II are arranged in a mutually vertical manner.
As preferable, length of the decreased food more than fixed mount.
As preferable, reinforcement is provided between two fixed mounts, the angle between the reinforcement and fixed mount is
45°。
As preferable, the junction of the reinforcement and fixed mount is located at the center of fixed mount.
As preferable, the length of the movable handgrip is more than the width of shaft coupling.
As preferable, the cross section of the movable handgrip is rectangle or arcuate structure.
The utility model has the advantage of：
When dismantling impeller, it is only necessary to which a people can easily pull down, while safety, quick, not damage equipment, and can be with
It is applied on the shaft coupling of different-diameter.
