Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, a large torque ratchet wrench comprises a connecting handle 1, a wrench 2 is fixedly mounted at the left end of the connecting handle 1, a handle 3 is movably connected at the right end of the connecting handle 1, and an adjusting mechanism 4 is arranged inside the handle 3.

Referring to fig. 2, a notch 12 is formed in the connecting handle 1, a first magnet 11 is fixedly mounted at the left end of the inner wall of the notch 12, and a guide plate 13 is fixedly mounted in the notch 12.

Please refer to fig. 3, the inside connecting rod 41 that includes of adjustment mechanism 4, both ends swing joint has a movable rod 42 about connecting rod 41, the one end swing joint that connecting rod 41 was kept away from to movable rod 42 has spacing wheel 43, connecting rod 41 outer fixed surface is connected with the stopper 44, connecting rod 41 left end fixed mounting has second magnet 45, connecting rod 41 right-hand member is provided with handle 46, cavity 31 has been seted up to handle 3 inside, spanner 2 internally mounted has the ratchet, connecting handle 1 right-hand member external diameter is less than cavity 31 internal diameter, cavity 31 outer surface is fluted, the interval between recess interval and the notch 12 is the same, movable rod 42 has two, two 24 are close to the one end swing joint of connecting rod 41, and internally mounted has volute spring.

The working principle is as follows: when the wrench is started, all parts are taken out of the tool box, the connecting handle 1 is inserted into the handle 3 at the moment, the connecting rod 41 penetrates through the handle 3, the handle 46 is rotated at the moment, the connecting rod 41 is limited and is convenient to pull, the screw is rotated, the screw needs to be pre-tightened at the moment, the handle 46 is pulled away at the moment, the connecting rod 41 is driven to move rightwards, the first magnet 11 and the second magnet 45 are separated, meanwhile, the connecting rod 41 pulls the limiting wheel 43 through the movable rod 42, the limiting wheel 43 clamped in the inner groove of the cavity 31 contracts towards the inside of the connecting handle 1, the connecting handle 1 and the inner part of the handle 3 are limited and disappear at the moment, the handle 3 is pulled rightwards at the moment, the length of the wrench handle is prolonged, meanwhile, the handle 46 is pushed, the connecting rod 41 is driven to move leftwards, the limiting wheel 43 is connected through the inner structure, the limiting wheel 43 is matched with the inner groove of the cavity 31 again, the limiting between the connecting handle 1 and the handle 3, the handle 3 is limited, the length of the wrench is prolonged, the torque is increased, and the effect of the wrench is achieved.
