Lithium battery dry wall screwdriver capable of automatically feeding screws

Abstract

The invention discloses an automatic screw feeding lithium battery dry wall screwdriver which comprises a lithium battery brushless dry wall screwdriver body, a power key switch and a fixing box, the power key switch is arranged at the front end of the surface of the lithium battery brushless dry wall screwdriver body, and a connecting rod is mounted at the bottom of the surface of the lithium battery brushless dry wall screwdriver body; and a fixing box is mounted at the bottom end of the connecting rod. Through the arrangement of the limiting sleeve, the stopping bolt and the fixing hole and the matching work of the limiting sleeve, the stopping bolt and the fixing hole, after a screwdriver of a proper model is selected, the stopping bolt is screwed, the screwdriver can be fixed, the fixing mode of double thread connection is adopted, the stability of the device during working can be improved, the arrangement of a control motor is adopted, and the working efficiency is improved. The output end of the limiting sleeve can drive the limiting sleeve to rotate, so that the screwdriver works, in addition, the fixing plate and the containing clamp are matched for work, different screwdrivers of various models can be fixed, and then the working speed of workers is increased.

Description

technical field [0001] The invention relates to the technical field of lithium battery brushless drywall screwdrivers, in particular to a lithium battery drywall screwdriver for automatic nail feeding. Background technique [0002] Lithium battery brushless drywall screwdriver is a tool that uses a lithium battery pack as power, and then drives the output shaft through a transmission mechanism and a nail feeding accessory device.

Problems solved by technology

The utility model uses a booster unit to increase the voltage of the control unit to maintain the motor to work at the rated voltage for a long time”, but the control structure of the above-mentioned device is difficult to judge the use time of the staff when it is used, and it does not have a good real-time control function. Thereby it is easy to make the energy consumption of the device larger;

[0007] 4. The patent document CN214923933U discloses a lithium battery screwdriver, "comprising an outer shell with a cavity and an inner shell with a cavity, the inner shell is fixed in the cavity of the outer shell by screws, and the front end of the outer shell is fitted with a front end Cover, the tail end of the inner shell is fitted with a rear end cover, the cavity of the inner shell is installed with a rod and a motor, the output end of the motor is connected to the input end of the rod, and the rod The output end of the output terminal passes through the front end cover, and the screws are located between the front end cover and the rear end cover. Through the double-layer design of the outer shell and the inner shell and the fitting installation of the front end cover and the rear end cover, the screws are transferred to the outer shell , and through the fitting and sealing of the front end cover and the rear end cover, so that no screw holes or screws are exposed on the surface of the shell, the overall effect is good and beautiful.” However, the above-mentioned device does not have a good arrangement and collection structure for screwdrivers, and it is easy to cause lost, lack of utility
