Problems solved by technology
[0002] At present, most wrenches are operated in a more convenient and safe environment. When encountering high-altitude operations, it is inconvenient, or the safety factor is reduced. When people stand on a ladder or an overhead stool, the operation is very inconvenient and unsafe, and sometimes it may be unsafe. For this reason, to solve and overcome such problems, it is necessary to research and innovate a tool , it can operate and work safely when encountering such an environment. Therefore, it is necessary to improve the existing tools from the structural and technical levels in order to overcome the above problems

Embodiment Construction
[0006] A new type of gear wrench, which is composed of a whole gear wrench (1), a wrench (2), a wrench screw shaft (3), a steel strip (4), a gear shaft support (5), and a pin type roller (6) , the arc-shaped rear teeth of the adjustable wrench (7), the socket of the external force handle (8), the fourth-stage gear shaft (9), the fourth-stage gear (10), the gear support bearing (11), and the third-stage gear (12) , the secondary gear (13), the first stage gear shaft teeth (14), the first stage large wheel rocking ring (15), and the first stage large wheel shaking ring handle (16), are composed together, and it is characterized in that, when running into the implementation work In the environment, first align the wrench teeth (2) with a suitable nut, manipulate the die screw shaft (3) to tighten the nut, and then use an external force tool. The external force handle implements effective clamping and compacting in the socket (8), After adjusting the posture again, stir the first-...

The invention relates to a novel gear wrench which is mainly suitable for tightening or loosening of nuts in air operation and narrow places. Mutual action of large and small gears is mainly utilizedfor reducing or increasing the force of the wrench, and particularly a plurality of large gears and small gears are matched for mutual action to reduce or increase torque force. When the wrench is manufactured, a plurality of gear shaft seats are welded on an iron plate strip to support a gear shaft with a small head, when the large gears are rotated, small gear shafts can be stably and effectively supported, the final-stage gear shaft on the topmost portion is directly connected with a monkey wrench to form a T shape, the other end of the monkey wrench is provided with an external force handle inserting hole, the monkey wrench is connected with an external force handle through a plug pin type roller shaft, the lower side is welded to the steel plate strip, by means of the torque effect ofthe external force handle, the head-stage large gear is rotted, force is transferred to the end of the monkey wrench stage by stage, the nut can be twisted to be loosened or tightened, and thereforea work task is completed.
Description
technical field [0001] This gear wrench belongs to the category of tools. Background technique [0002] At present, most wrenches are operated in a more convenient and safe environment. When encountering high-altitude operations, it is inconvenient, or the safety factor is reduced. When people stand on a ladder or an overhead stool, the operation is very inconvenient and unsafe, and sometimes it may be unsafe. For this reason, to solve and overcome such problems, it is necessary to research and innovate a tool , It can also operate and work safely when encountering such an environment. Therefore, it is necessary to improve the existing tools from the structural and technical levels in order to overcome the above problems. Contents of the invention [0003] A new type of gear wrench, which is mainly suitable for fastening or loosening nuts in aerial work and narrow places. It mainly uses the interaction between large and small gears to reduce or increase the force of the w...
