Furthermore, the lower end face of the base is fixedly connected with a rubber anti-slip pad, so that the friction between the device and the ground when the device is placed is increased, and the stability of the device is improved.

Furthermore, the front end face of the supporting rod is provided with scale marks for marking the height of the current cross rod.

The utility model discloses the beneficial effect who has is: the inserted bar is pulled out, so that the height of the supporting bar can be adjusted, and the current height of the device can be fixed by inserting the inserted bar into the slot again by using the pulling force generated by the first spring; the device uses the fixed cover of back right pulling to end, makes it break away from with left horizontal pole, can rotate left horizontal pole and right horizontal pole this moment and make it receive and put in the bracing piece of U-shaped, only needs to reduce the bracing piece height afterwards and makes the bracing piece receive and put in the support column and rotate the support column to receiving the inslot and can fold whole device to reduce the space and occupy.
