Technical Field
[0001] The utility model relates to the technical field of wrenches, in particular to an axially driven hollow unobstructed sleeve lithium battery wrench. Background Art
[0002] A wrench is a commonly used installation and disassembly tool. It is a hand tool that uses the principle of leverage to turn bolts, screws, nuts and other threaded fasteners with openings or holes. Wrenches are usually made of structural steel made of carbon or alloy materials. Wrenches usually have openings or holes for clamping bolts or nuts at one or both ends of the handle. When used, external force is applied to the handle along the direction of thread rotation to turn the bolt or nut.
[0003] The existing wrenches are divided into two types: electric and manual. The existing electric wrenches have relatively simple functions and have certain shortcomings in actual use. When tightening nuts, the existing electric wrenches are affected by the length of the screws and cannot be used in multiple directions and types. They cannot be normally and conveniently operated in narrow spaces and special environments. Based on the existing technical deficiencies, the utility model designs an axially driven hollow unobstructed sleeve lithium-ion wrench. Utility Model Content

[0006] As a preferred technical solution of the utility model, the second shell is fixedly connected to the third shell, and the third shell is arranged at a half position inside the second shell.
[0007] As a preferred technical solution of the present utility model, a clamping plate is provided inside the third housing, and the clamping plate is rotatably connected to the extension column.
[0008] As a preferred technical solution of the utility model, a hexagonal groove is provided inside the second bevel gear.
[0009] As a preferred technical solution of the utility model, a mounting groove is provided on the outer surface of the non-obstructive casing, and a forward and reverse switch is arranged inside the mounting groove.
[0010] As a preferred technical solution of the utility model, an output shaft is arranged inside the servo motor, and the output shaft is fixedly connected to the transmission shaft.
[0011] As a preferred technical solution of the utility model, a battery assembly is mounted inside the unobstructed housing, a connecting wire is provided on one side of the battery assembly, and one end of the connecting wire is connected to the servo motor.
[0012] Compared with the prior art, the utility model has the following beneficial effects:
[0013] The axially driven hollow non-blocking sleeve lithium-ion wrench has a non-blocking sleeve and a rotating structure. Due to the meshing of the second bevel gear and the first bevel gear, when the device is running, the device is passed over a slightly longer screw and the through slot is clamped at the nut. The second bevel gear drives the first bevel gear to rotate forward and reversely through the drive of the servo motor, thereby the nut can be removed. Since the non-blocking sleeve is relatively slender in shape, and the hollow non-blocking sleeve of different sizes and other workpieces are replaced to perform 90-degree electric wrench operations, since there is no obstruction in the center and the operation is not affected by screws of any length, the device can perform special operations in narrow places up, down, left, and right. Moreover, through the hexagonal inner corner of the through slot, a variety of tool parts can be matched to perform longitudinal operations, thereby achieving the purpose that the wrench can be operated in a small space and is not affected by the length of the screw.
[0014] The utility model relates to an axially driven hollow non-blocking sleeve lithium battery wrench. Through the setting of the hexagonal slot, different tools such as screwdrivers and drill bits can be inserted into the hexagonal slot to realize other works such as drilling and nailing.
