Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature includes the first feature being directly above and obliquely above the second feature, or simply meaning that the first feature is at a lesser level than the second feature.
The present embodiment will be described in detail with reference to fig. 1 to 4. The high-bearing diamond-shaped pipe pull rod assembly comprises a handle 1, a pull rod 2, a panel 3 and a foot plate 4. The cross section of the pull rod 2 consists of a first straight edge 201, a second straight edge 202, an arc-shaped edge 203 and a third straight edge 204. The first straight side 201 is connected to the second straight side 202 by a first arc segment 205, the second straight side 202 is connected to the arc side 203 by a second arc segment 206, the arc side 203 is connected to the third straight side 204 and the third straight side 204 is connected to the first straight side 201 by a third arc segment 207.

The angle of the arc-shaped edge is 95 degrees. The angles referred to in the present embodiment are all the angles of the line segments of the inner surface of the cross section of the test pull rod, and the thickness of the pull rod is uniform.
In this embodiment, the pull rod 2 comprises a small tube 21, a middle tube 22 and a large tube 23 which are sleeved in sequence. One end of the small tube is fixed with the handle 1, and the other end is sleeved at one end of the middle tube 22 and can extend and retract in the middle tube 22. The other end of the middle tube 22 is sleeved inside one end of the large tube 23.
