Description
Technical Field
The utility model belongs to the field of machinery, concretely relates to big torque wrench suitable for big space operation.
Background
The wrench is a common mounting and dismounting tool, and is a manual tool for screwing bolts, screws, nuts and other screw threads to tightly hold open or trepanning fasteners of the bolts or nuts by utilizing the lever principle. The traditional spanner is small in size and suitable for being operated in a small space, but has the following defects: firstly, the wrench engaging part is small and is not suitable for the operation of large-volume objects; second, the length of the arm of the wrench is usually not too long, which is suitable for one-handed operation, so the torque is too small, and the torque for mounting and dismounting large instruments is not enough.
Disclosure of Invention
The purpose of the invention is as follows: an object of the utility model is to provide a can be in operation in great space, torsion stronger, the bigger spanner of processing object volume to above-mentioned problem.
The technical scheme is as follows: in order to achieve the above object, the present invention is specifically completed as follows: a large torque wrench suitable for large-space operation comprises a main rod and an auxiliary rod, wherein a first groove is formed in the middle of the main rod, a sawtooth structure is arranged in the first groove, two grooves are respectively formed in the two sides of the sawtooth structure of the main rod, and a first through hole is formed in each groove; a sawtooth structure is arranged in the middle of the auxiliary rod corresponding to the first groove of the main rod, a third groove is arranged on two sides of the sawtooth structure of the auxiliary rod corresponding to the second groove of the main rod, and a second through hole is formed in the third groove; the inner edges of the first through hole and the second through hole are provided with internal threads, and the first through hole and the second through hole are fixedly connected through a screw structure; the length of main pole is longer than the auxiliary rod, and the main pole both ends are equipped with the handle.
Preferably, the screw structure includes the lug in middle part and connects the screw rod in lug both sides, and the lug is cylindrical, is equipped with a plurality of counter bores on the circumference of lug, and the screw rod has the external screw thread that suits with No. one through-hole, No. two through-hole internal threads.
Furthermore, the lug in the screw rod structure and the screw rod are of an integrated structure.
The utility model discloses concrete during operation connects soon through synchronous and mobile jib and auxiliary rod with two screw rod structures, then screws screw the screw rod structure in step again as for between the sawtooth structure of mobile jib, auxiliary rod, through the application of force to the mobile jib, twists the operation object at last. Preferably, two persons apply force to operate synchronously during the process of screwing the main rod and the auxiliary rod in the screw rod structure, and after the main rod and the auxiliary rod are fixed with an operation object, one person or more persons can be selected to operate according to the magnitude of the torque force.
Has the advantages that: the utility model discloses structural design is simple, and the torsion that produces increases several times or even more than tens of times than traditional spanner, simultaneously because whole spanner structure is that mobile jib and auxiliary rod combination form, if wherein some damage only need change corresponding part can, and the processing object as long as can be by the interlock of sawtooth structure can, no matter be regular or irregular object homoenergetic effect.
