Problems solved by technology

[0010] In these reports, the sheet metal pulling tool using the principle of leverage is limited in the range of use and the strength of the pulling force because it is a hand-held tool.
However, the puller that uses oil pressure as power can obtain a large pulling force, but the weight of the puller itself is relatively large, which increases the inconvenience of operation.
As for the puller of the rack and pinion mechanism, since there is no specific means for enhancing the pulling force, the strength of the pulling force may be limited.

Abstract

The sheet metal pullout appliance of the invention is composed of a stretcher shell forming the external container; a shaft component capable of advancing and regressing freely relative to the stretcher shell and provided with gear rack at one plane along the length direction; more than two gear components with pinion included, which are set in the shell for advancing and regressing the shaft component, and an external force guiding device for applying stretching force to the gear components, the gear components amplify and transfer guided external force to the force pulling out the shaft component by gear ratio of the gear components. The positive effect of the present invention is that: (1) external is amplified by the gear ratio of the gear components to form stronger pullout force; (2) pullout force and pullout amount are optionally set by adjusting gear ratio through stretch lever; (3) depression with comparative high hardness of the sheet metal can be pulled out; (4) the sheet metal pullout appliance owns lower working intensity, easy operation, light weight, and high efficiency.

Description

【Technical field】 [0001] The invention relates to the technical field of automobile repair, specifically, a sheet metal pulling tool for pulling out and repairing car body panels and bumper recesses, more specifically, changing the gear ratio through several gears to achieve a relatively Sheet metal puller with low torque and large pulling force. 【Background technique】 [0002] When repairing a damaged car body (car body trim), as a simple and quick repair method for the dents on the metal sheet, in recent years, people have tried to use various sheet metal pullers to remove the dent from the outside. The repair method of pulling out the body trim, using this repair method, does not need to open the back of the recessed part, but can directly repair the recessed part from the outside, which greatly shortens the repair time. [0003] The sheet metal pulling tools (also known as pullers) used in this repair method are currently common: welding nozzles with welding electrodes ...
