Description

Waxing machine

Technical Field

The utility model relates to a handheld electric tool field especially relates to a waxing machine.

Background

Typically, power tools, such as polishers or polishers, for fine work surfaces of various contours, including exterior automotive finishes, are controlled and manipulated efficiently and precisely on the work surface by an operator holding a handle. Such power tools typically include a motor that drives a working member, such as a polishing or waxing pad, in orbital contact with a work surface. In order to properly treat the work surface while preventing damage thereto, it is important that the operator be able to accurately guide the movement of the working element along the work surface and at the same time control the pressure that the working element applies to the work surface. For example, if the tool is used under excessive pressure, such as to control and prevent the full weight of the tool from being applied to the working element, thereby affecting the working surface, the finish of the working surface is easily damaged or even destroyed. On the other hand, too little applied pressure tends to result in an inadequate surface finish, or increased operating time to accomplish the desired finish.

In order to improve efficiency, it is also desirable for the operator to be able to cover a relatively large area on the work surface while maintaining control over the application pressure and path of the tool during operation. While operating the tool, the vibration response due to orbital motion increases, while accuracy and precision may be compromised with extended arms based on the volume and weight of the tool itself.

Another problem is that the power cord for powering the motor, which is typically directly connected to the housing, requires constant adjustment of the operator's support for the tool and grip of the handle while operating the tool, and not only is the working distance limited by the length of the power cord, but there is also the problem of inadvertent separation between the socket and the power cord.

Accordingly, there is a need for a power tool, particularly one that drives its working components on rails, that is bulky to enable an operator to effectively and accurately control the working components and facilitate work over a relatively large area on a work surface, yet is ergonomic.
