DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0018] Reference Figures 1 to 3, an adjustable mobile power-supply towing arm, comprising a vertically arranged towing rod 1, a base arm assembly 2 which can move up and down along the towing rod and is arranged perpendicular to the towing rod, and a base assembly 3 which can move forward and backward horizontally along the base arm assembly;

[0019] The base arm assembly 2 includes a clamping plate assembly 21 sleeved on the towing rod, a forearm 22 arranged at one end of the clamping plate assembly, and a base arm 23 sleeved on the forearm;

[0020] The clamping plate assembly 21 includes a mounting plate 211 mounted on the forearm, limiting bolts 212 respectively arranged around the mounting plate, and a clamping plate 213;

[0021] During installation, the limit bolts 212 are placed on both sides of the towing rod 1, the mounting plate 211 is placed on one side of the towing rod 1, and the clamping plate 213 is fixed to the limit bolts 212 through nuts, so as to fix and clamp the towing rod 1. If adjustment is required, loosen the nut to lose the clamping force, then move up and down, move to the appropriate position and tighten the nut.

[0022] A plurality of fixing holes 24 are provided on the forearm and the base arm, and the base wall can move forward and backward along the direction of the forearm, and then the forearm and the base arm are fixed by fixing nuts to achieve adjustment.

[0023] The base assembly 3 includes a second clamping plate assembly 31 sleeved on the base arm, a fixed base 32 clamped and fixed by the second clamping plate assembly 31, and a base 33 with an adjustable angle and arranged on the fixed base;
