Abstract
The utility model relates to a screwing wrench for a round-head nut, belonging to the field of the wrench for screwing the nut and comprising a handle, a vertical arm, a clamping disc and a clamping head, wherein the handle is connected with the vertical arm which is connected with the clamping disc with a semicircular structure; and the bottom part of the clamping disc is connected with the clamping head supporting the clamping disc. The wrench is used for screwing various round-head nuts on large hydraulic machine equipment; as the clamping disc is a semicircular structure and matched with the handle, the effect of screwing randomly can be achieved no matter how large the nut is. The screwing wrench has the advantages of having high construction efficiency and low construction intensity and saving manpower and mechanical cost; and the screwing wrench has the advantages of having simple structure and small volume, being economical and practical, having convenient operation and convenient carrying, and the like.
Description
Technical field
The utility model relates to the spanner that a kind of fastening nut is used, and particularly relates to a kind ofly being applicable to that various cheese head screws are by tight bolted cheese head screw impact wrench on the large hydraulic machine equipment.
Background technology
In the connection of large-size extruder memorial archway frame, owing to the position concerns reason or specific (special) requirements is arranged and usually adopts cheese head screw by tight bolt, general Wrench can not satisfy cheese head screw by tight needs.
Along with development of science and technology, the progress in epoch, the various parts that connect with snap bolt more and more are employed, and the demand of the cheese head screw tightening tool of all size size is also constantly increased.But the spanner of the coupling that still suitable at present multiple cheese head screw is tightly used.
The content of utility model
Goal of the invention of the present utility model is at the deficiencies in the prior art, provides a kind of cheese head screw that guarantees to tighten convenient and reliablely, improves the mechanization degree of construction and the cheese head screw impact wrench of efficiency of construction simultaneously.
Realize the foregoing invention purpose by the following technical solutions: a kind of cheese head screw impact wrench, described spanner comprise handle, upright arm, chuck and dop, and described handle is connected with upright arm, and upright arm is connected with chuck, and the bottom of this chuck is connected with the dop of support chuck.
Described chuck is a semicircular structure.
Adopt technique scheme, this spanner to be used for tightening of various cheese head screws on the large hydraulic machine equipment, because its chuck is a semicircular structure, cooperate handle, no matter nut is much, all can reach the effect of arbitrarily tightening.Have the efficiency of construction height, construction intensity is low, save the advantage of manpower and machinery expenses, and the utility model is simple in structure, and volume is little, have economical and practical, easy to use, advantage such as be easy to carry.
