When the upper part of the first positioning pin 71 is separated from the first countersunk hole 614, the rotation limitation of the second handle 6 is realized. After the hole 614 is inserted, the rotation limit of the second handle 6 is released. At this time, the second handle 6 can be rotated and adjusted so that the second handle 6 is at a more suitable holding angle; an adjusting oblong hole 612 perpendicular to the first countersunk hole 614 is provided on the upper part of the second handle 6, and a screw 73 is provided in the adjusting oblong hole 612. The threaded end of the screw 73 is fixedly connected to the first positioning pin 71, and the screw 73 can move up and down in the adjusting oblong hole 612. In actual application, the screw 73 is pushed downward to realize the separation of the upper part of the first positioning pin 71 from the corresponding first countersunk hole 614. At this time, the swing angle of the second handle 6 can be adjusted. When the downward push on the screw 73 is released and the placement angle of the second handle 6 is adjusted, the upper part of the first positioning pin 71 is smoothly inserted into the corresponding first countersunk hole 614 under the push of the second spring 72, thereby realizing the swing positioning of the second handle 6.
[0027] A second specific implementation method for realizing angle adjustment and positioning of the second handle 6 is as follows: a limiting recess 613 is provided on both the left and right walls of the hinge seat 61, a fifth through hole which is connected with the hinge through hole of the hinge support ear 52 is provided on the inner wall of the limiting recess 613, a left positioning adjustment cover 81 is sleeved in the limiting recess 613 on the left side, a first connecting column 811 in the middle part of the left positioning adjustment cover 81 is sleeved in the corresponding fifth through hole, a conical spring piece 83 is provided between the left positioning adjustment cover 81 and the corresponding inner wall of the limiting recess 613, and the conical spring piece 83 is sleeved on the first connecting column 811, and the conical spring piece 83 has a certain compression reset elasticity, a fourth threaded recess 812 is provided on the first connecting column 811, a right positioning adjustment cover 82 is sleeved in the limiting recess 613 on the right side, and a fourth threaded recess 812 is provided on the fourth threaded recess 812, a right positioning adjustment cover 82 is sleeved in the limiting recess 613 on the right side, and a fifth threaded recess 812 is provided in the middle part of the right positioning adjustment cover 82 A second connecting column 821 docked with the first connecting column 811, a countersunk through hole 822 is set on the second connecting column 821, a bolt passes through the countersunk through hole 822 and is tightened in the fourth threaded countersunk hole 812 to achieve fixed connection between the first connecting column 811 and the second connecting column 821. After the first connecting column 811 and the second connecting column 821 are fixedly connected by the bolt, the left positioning adjustment cover 81 and the right positioning adjustment cover 82 are then fixedly connected.

A plurality of second adjustment holes 522 are arranged on the right side wall of the hinged support ear 52, and are evenly spaced along the circumferential direction of the hinged hole. A plurality of second positioning pins 823 corresponding to the second adjustment holes 522 are arranged on the left side wall of the right positioning adjustment cover 82, and the second positioning pins 823 can be inserted into the second adjustment holes 522. In actual application, when the left positioning adjustment cover 81 is not squeezed to the right, the second positioning pin 821 can be inserted into the corresponding second adjustment hole 522 under the pushing action of the conical spring piece 83. The second positioning pin 821 is inserted into the second adjustment hole 522 to realize the rotation limit of the second handle 6. When the left positioning adjustment cover 81 is pressed to the right, the conical spring piece 83 is compressed, thereby realizing the overall rightward movement of the left positioning adjustment cover 81 and the right positioning adjustment cover 82. When the right positioning adjustment cover 82 moves to the right to a certain extent, The second positioning pin 821 is then disengaged from the second adjusting hole 522. When the second positioning pin 821 is disengaged from the second adjusting hole 522, the rotation limit of the second adjusting hole 522 on the second positioning pin 821 is released, thereby realizing the rotation adjustment of the second handle 6. When the top pressure on the left positioning adjustment cover 81 is released, at the same time, the angle of the second handle 6 is adjusted to the right position, and the conical spring piece 83 pushes the left positioning adjustment cover 81, so that the second positioning pin 821 is inserted into the corresponding second adjusting hole 522, thereby realizing the fixation of the second handle 6.
[0028] In actual application, in order to improve the surface friction coefficient of the first handle 3 and the second handle 6 , anti-slip patterns 101 are provided on the outer side walls of the first handle 3 and the second handle 6 .
