[0037] Please see Figure 2 - Figure 4 The first transmission arm 104, the second transmission arm 106, and the third transmission arm 140 are connected in series.

[0038] In one specific embodiment, the first transmission arm 104, the second transmission arm 106, and the third transmission arm 140 in series structure facilitate simultaneous control of opening and closing, thereby improving the clamping and positioning efficiency of the frame body 200.

[0039] Please see Figure 2 - Figure 4 The first pressure bar 122, the second pressure bar 132 and the third pressure bar 142 are all made of hollow stainless steel.

[0040] In one specific embodiment, the first pressure bar 122, the second pressure bar 132, and the third pressure bar 142, made of hollow stainless steel, can reduce their weight while increasing their strength, thereby reducing cost and extending their service life.

[0041] Working principle: When positioning and clamping electric vehicle frames of different sizes, the frame body 200 is first placed on the upper end of the receiving plate 102, and the two first pressing blocks 160 are controlled to move along the first sliding groove 150 to adjust the distance, thereby clamping and positioning the chassis of the frame body 200 of different sizes. At the same time, several first transmission arms 104 at one end of the receiving plate 102 rotate so that their end inserts are inserted into the reserved holes of the frame body 200, thereby further positioning them. The second transmission arms 106 on both sides of the receiving plate 102 rotate to adjust the angle so as to position and clamp the frame body 200 from both sides. Finally, the two pressing rods 110 at the upper end of the gantry frame 108 facilitate pressing and fixing the frame body 200 from the top, thereby enhancing the versatility and safety of the positioning fixture.
