Description

Multipurpose lithium electric wrench Technical Field The application relates to the technical field of tools, in particular to a multipurpose lithium battery wrench. Background The "lithium battery wrench" refers to an electric wrench using a lithium battery as a power source. Lithium battery wrenches are a type of power tool commonly used to tighten or loosen bolts and nuts. Lithium batteries are a lightweight, high energy density battery type and are therefore widely used in power tools to provide a reliable power source. Electric wrenches are often designed to improve work efficiency, particularly in situations where a large number of bolts or nuts need to be tightened. The current chinese patent of publication No. CN216265724U discloses a lithium battery spanner, which comprises a device housing, device housing front end bolted connection has the mounting panel, mounting panel fixedly connected with adapter shell, be provided with first helical gear and second helical gear in the adapter shell, the spread groove has been seted up to one side of first helical gear, the top fixedly connected with adapter second of second helical gear, the bottom fixedly connected with extension axle of second helical gear, fixedly connected with correction board in the adapter shell. When the lithium battery wrench is used, the connecting groove, the adapter II, the first bevel gear and the second bevel gear are arranged, so that the rotating head of the original lithium battery wrench can be inserted into the connecting groove and can drive the first bevel gear to rotate, and the adapter II and the second bevel gear are driven to rotate. For the related technology, at present, when a lithium battery wrench is operated for a single time, only bolts or nuts with one size can be screwed or unscrewed, if bolts or nuts with other sizes are required to be screwed or unscrewed, the adapter needs to be manually replaced, in addition, when the bolts or nuts rust and age due to long-time use, the bolts or nuts need to be turned, so that the bolts or nuts can be separated from a workpiece, the working strength of workers is increased, and the working efficiency is further reduced. Disclosure of Invention The technical problem to be solved by the invention is to provide a multipurpose lithium battery wrench, which solves the technical problems that when the conventional lithium battery wrench is operated for a single time, only bolts or nuts with one size can be screwed or unscrewed, if the bolts or nuts with other sizes are required to be screwed or unscrewed, the adapter is required to be manually replaced, and when the bolts or nuts are rusted and aged due to long-time use, the bolts or nuts are required to be turned, so that the bolts or nuts can be separated from a workpiece, the working strength of workers is increased, and the working efficiency is further reduced. In order to achieve the above purpose, the present invention provides the following technical solutions: the multipurpose lithium battery wrench comprises a wrench shell, wherein an operation port is formed on one side of the wrench shell, and the multipurpose lithium battery wrench is characterized in that: the conversion assembly is used for installing different drill bits or conversion heads, and the different drill bits or the different conversion heads on the conversion assembly correspond to the operation ports of the wrench shell along with the conversion of the conversion assembly in the wrench shell; the pushing assembly is used for pushing the drill bit or the conversion head on the conversion assembly to one side close to the operation port; And the clamping assembly is used for clamping one end of the bolt or the nut, and simultaneously can clamp different drill bits or switching heads pushed to one side of the operation port from the switching assembly. Through above-mentioned technical scheme, install different drill bits and conversion head on conversion subassembly, during the use, correspond with the operation mouth through conversion head conversion different drill bits or conversion head, then propulsion subassembly will correspond drill bits or conversion to the promotion to the one side that is close to the operation mouth, afterwards the drill bit or the conversion head that will be close to operation mouth one side of clamping assembly clamp, simultaneously, clamping assembly can also press from both sides the bolt and the nut of different signals, make the spanner when using, under the condition that does not need the manual change conversion head, can accomplish the screwing up or loosening of different model bolts and nuts, in addition, can also carry out the turning to ageing bolt or nut, make bolt or nut break away from the work piece, reduce staff's working strength, promote work efficiency. Further, the conversion assembly comprises a rotating disc, the rotating disc is rotatably arranged in the wrench shell, a sliding cavity is formed
