Benefits of technology
The present invention is a car fender trim expander that has a simple structure and is easy to operate. It can be adjusted for different types of cars. The invention includes a position limiting device that is located between the telescopic tube and the sliding member. The device can move between a fixed position and an acting position. When the device is at the fixed position, it limits the stretching of the telescopic tube and the movement of the sliding member. However, when the device is at the acting position, it allows for the stretching of the telescopic tube and the movement of the sliding member caused by an external force. This results in a simple structure that is convenient and easy to adjust and operate.
Problems solved by technology
However, the handle is easily forced to rotate by external force and thus causes the internal tube to withdraw against the external tube.
As a result, the sudden withdrawal of the tool during the operation can cause the operator to be frightened and wounded.
Moreover, the swinging of the telescoping rectangular tube arrangement against the affixing flange can only be slowly adjusted by adjusting the screwing motion of the threaded spindle, wherein the time needed for adjusting is relatively long, and the structure of the tool is relatively complicated.

Abstract
A car fender trim expander includes a fixing disk, a telescopic tube, a sliding member, a linkage assembly, a roller, and a position limiting device. Therein, the fixing disk is to be installed on a wheel axle and rotates together with the wheel axle. The telescopic tube has a first and a second end, while the first end is pivotally connected to the fixing disk. The sliding member is slidingly disposed on the periphery of the telescopic tube. The linkage assembly is disposed between the sliding member and the fixing disk. The roller is disposed on the second end of the telescopic tube for contacting the inner edge of the fender trim. The position limiting device is for adjusting the stretching and pivotal swinging of the telescopic tube. Thereby, the convenience and easiness for operation is achieved.
Description
BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to expanders, and more particularly, to a car fender trim expander.[0003]2. Description of the Related Art[0004]U.S. Pat. No. 816,678 disclosed a lip-rolling and flanging tool for bending back or widening fender-wheelwell edges of motor vehicles, comprising an affixing flange for being fixed on the wheel axle after the wheel is removed. Said flange includes a telescoping rectangular tube arrangement, which comprises an external tube and an internal tube capable of sliding against each other, with a threaded spindle rotatably disposed between the external tube and the affixing flange. Through the rotation of the threaded spindle, an inclination angle of the external tube against the affixing flange is adjusted, thereby changing the angle of the external tube against the affixing flange. A handle is disposed between the external tube and the internal tube for controlling the stretching of the...
