Description
Technical field
It the utility model is related to a kind of Simple spanner.
Background technology
Existing spanner is generally used for dismantling the standard parts and components such as nut, but has in many plant equipment large-scale
The parts such as end cap need to dismantle, and generally require and go to pound with sledgehammer, it would be desirable to after the parts such as end cap of dismounting pound loosening, then enter
Row dismounting, wastes time and energy, and noise is big, is unfavorable for the physical and mental health of operating personnel.
Utility model content
The utility model is directed to above-mentioned the shortcomings of the prior art, there is provided a kind of letter suitable for large parts dismounting
Easy spanner.
The technical scheme that the utility model solves above-mentioned technical problem is as follows：A kind of Simple spanner, including chain and connecting rod,
The chain can slide back and forth along the connecting rod, and one end of the chain is fixed on the front end of the connecting rod, the chain
Other end connecting screw, the screw rod are connected with handwheel after passing through the thread bush, and the screw rod connects with the screw thread external threading
Connect, the thread bush is fixed on the connecting rod.
Further, the lower section of described chain connecting screw one end is provided with sliding block, and the connecting rod is provided with and the sliding block phase
The chute of adaptation.
Further, the lower end of the screw rod is provided with sliding block, and the connecting rod is provided with the chute being adapted with the sliding block.
The beneficial effects of the utility model are：By rotation hand wheel with regard to chain can be made to clamp the parts to be dismantled, then
The rear end to connecting rod exerts a force again, time saving and energy saving with regard to that can be easy to dismantle large-scale parts；In addition, chain is used in difference
The dismounting of the parts of shape.
