The positioning frame (1) has a horizontal frame (11) and a vertical frame (12). The horizontal frame (11) has two longitudinal tubular sections (111) and two lateral tubular sections (112) which are connected to each other. Both longitudinal poles are attached to the struts (21) from the handle by two connection sections (114), and several attachment bars (115) are attached to both longitudinal poles. The vertical frame (12) has two vertical poles (121) which are connected at one end to the lateral poles and at the other end to two connection elements (122) and two plug-in elements (123). |
