1. A touch substrate providing with a mounting hole, the touch substrate having a hole edge region around the mounting hole, and a main touch region located outside of the hole edge region, and the touch substrate comprising:
a substrate;
a plurality of first touch units disposed on the substrate each extending in a first direction and including a plurality of first touch electrodes and a plurality of first connecting portions, and each first connecting portion being electrically connected to two adjacent first touch electrodes; and
a plurality of second touch units disposed on the substrate and insulated from the plurality of first touch units, each second touch unit extending in a second direction and including a plurality of second touch electrodes and a plurality of second connecting portions, and each second connecting portion being electrically connected to two adjacent second touch electrodes; and
the first direction intersecting with the second direction,
wherein an orthogonal projection of each first connecting portion on the substrate at least partially overlaps with an orthogonal projection of a second connecting portion on the substrate, and the first connecting portion and the corresponding second connecting portion form a connecting unit;
a plurality of connecting units located in the hole edge region are hole edge connecting units, and at least one of the plurality of hole edge connecting units is an adjustment connecting unit;
in a first touch unit corresponding to the adjustment connecting unit, a straight line where a line connecting centers of at least two first touch electrodes located in the main touch region is located is a first reference line;
in a second touch unit corresponding to the adjustment connecting unit, a straight line where a line connecting centers of at least two second touch electrodes located in the main touch region is located is a second reference line; and
an intersection point of the first reference line and the second reference line is a hole edge reference point; and
in a direction parallel to a plane of the substrate on which the plurality of first touch units and the plurality of second touch units are disposed, at least a part of the adjustment connecting unit is further from an edge of the mounting hole than the hole edge reference point.
