Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electric impact wrenches, in particular to a vertical impact wrench. BACKGROUND

[0002] A vertical impact wrench is a high-efficiency power tool designed for quickly disassembling large bolts and nuts. Its structure mainly consists of a motor, an impact mechanism, a transmission system, and a housing. The body is usually made of lightweight materials such as aluminum alloy, and the internal core is the impact mechanism, which is driven by the motor to rotate the flywheel to store energy, and releases instantaneous impact force when the preset torque is reached, converting rotational kinetic energy into high-frequency impact torque. This design allows it to produce tens of times the torque output of a regular wrench, making it particularly suitable for automotive repair, wind power equipment installation, rail transportation, and other industrial scenarios that require high torque operations.

[0003] Compared with traditional wrenches, vertical impact wrenches have significant advantages: the built-in impact mechanism can effectively overcome the resistance caused by thread rust, avoiding the operator from bearing the reaction force; adjustable torque settings can precisely control the tightening force, protecting delicate components; and with different size sleeves, it has strong versatility.

[0004] The vertical impact wrench currently on the market, such as the vertical lithium battery wrench with publication number CN210790755U, includes a main shell and a handle. The main shell is provided with a motor assembly and an impact transmission assembly, and the impact transmission assembly is located at the bottom of the motor assembly. The vertical lithium battery wrench also includes a lithium battery assembly, which includes a battery pack seat and a lithium battery pack. The lithium battery pack is detachably installed in the battery pack seat through a sliding pair and a locking mechanism.

[0005] For the related technology in the above, the inventors found that the battery pack and the impact transmission assembly are both arranged at the bottom end of the wrench, which causes the rotation torque to lengthen when the person holds the handle to move the wrench, resulting in discomfort for the person using it for a long time.
