When the first pin shaft 6 rises, the first hook rod 4 and the second hook rod 5 rise with the first pin shaft 6, the first inclined long hole 41 and the second inclined long hole 51 move upward and are subjected to the reaction force of the second pin shaft 7, so that the upper ends of the first hook rod 4 and the second hook rod 5 approach each other, and the first hook body 42 and the second hook body 52 retract into the plug middle cavity 31; when the first pin shaft 6 descends, the first hook rod 4 and the second hook rod 5 descend with the first pin shaft 6, the first inclined long hole 41 and the second inclined long hole 51 move downward and are subjected to the reaction force of the second pin shaft 7, so that the upper ends of the first hook rod 4 and the second hook rod 5 separate from each other, and the first hook body 42 and the second hook body 52 extend out of the plug middle cavity 31 to hook the side wall of the connection hole 101 of the automotive sheet metal part 100. It should be noted that the automotive sheet metal part 100 usually has a plurality of connection holes 101, and the shape and size of the support body 1 are not limited to Figures 1 - 5 the shape and size shown in the figure. Multiple sets of the sleeve 2, the positioning plug 3, the first hook rod 4, the second hook rod 5, the first pin shaft 6, the second pin shaft 7, and the pin shaft lifting assembly can be installed at intervals on one support body 1 to position and hook a plurality of connection holes 101 of the automotive sheet metal part 100.

[0017] Such as Figures 1 - 5As shown in the figure, the pin lifting assembly includes a "U"-shaped arm 8, a lever 9 and a spring 10. The upper parts of both ends of the "U"-shaped arm 8 are rotatably connected to both ends of the second pin 7. One end of the lever 9 is connected to the middle part of the "U"-shaped arm 8. The spring 10 is installed inside the lower end of the middle cavity 21 of the sleeve. The lower end of the spring 10 is elastically abutted against the support body 1, and the upper end of the spring 10 is elastically abutted against the first pin 6.

The lower parts of both ends of the "U"-shaped arm 8 are abutted and cooperated with the two ends of the first pin 6. When the lever 9 is pushed downwards, the lower parts of both ends of the "U"-shaped arm 8 can press down the first pin 6, so that the first pin 6 moves downwards against the elastic force of the spring 10. When the lever 9 is pushed upwards, the lower parts of both ends of the "U"-shaped arm 8 can release the downward pressure on the first pin 6, so that the spring 10 elastically pushes the first pin 6 to move upwards.

[0018] As Figures 1 - 5 shown, a sleeve connection seat 23 is provided at the bottom of the sleeve 2. The sleeve connection seat 23 is detachably connected to the support body 1 by screws.

The upper end of the plug middle cavity 31 is closed, and the lower end of the plug middle cavity 31 is communicated with the sleeve middle cavity 21.

[0019] As Figures 1 - 5 shown, the side parts of the first hook rod 4 and the second hook rod 5 are in sliding contact and cooperation, and the side parts of the first hook rod 4 and the second hook rod 5 are respectively in sliding contact and cooperation with the side wall of the plug middle cavity 31.

[0020] The working principle of the present utility model is as follows: First, set the positioning device of the automobile sheet metal part to the initial state. In the initial state, the spring 10 is in an open state. The two ends of the first pin 6 are located at the upper ends of the pin movable long holes 22. The second pin 7 is located at the lower ends of the first inclined long hole 41 and the second inclined long hole 51. The first hook body 42 of the first hook rod 4 and the second hook body 52 of the second hook rod 5 are respectively located inside the plug middle cavity 31 and do not protrude outwards. Then, align the connection hole 101 of the automobile sheet metal part 100 with the positioning plug 3 and place it on the positioning device, so that the positioning plug 3 is inserted upwards into the connection hole 101 of the automobile sheet metal part 100 (see Figure 5); Next, move the lever 9 downwards. The lower parts of both ends of the "U"-shaped arm 8 rotate and move downwards, forming a downward pressure on the first pin 6, pressing down the first pin 6 to overcome the elastic force of the spring 10 and descend. The two ends of the first pin 6 reach the lower end of the pin movable long hole 22. During this process, the first hook rod 4 and the second hook rod 5 descend along with the first pin 6. The first inclined long hole 41 and the second inclined long hole 51 move downwards and receive the reaction force of the second pin 7, causing the upper ends of the first hook rod 4 and the second hook rod 5 to separate from each other. The first hook body 42 and the second hook body 52 extend outwards from the plug middle cavity 31 and hook the side wall of the connection hole 101 of the automotive sheet metal part 100 (see Figure 5 ); Then, detect the automotive sheet metal part 10. Then, move the lever 9 upwards. The lower parts of both ends of the "U"-shaped arm 8 rotate and move upwards, releasing the downward pressure on the first pin 6. The spring 10 elastically pushes the first pin 6 upwards. During the upward movement of the first pin 6, the first hook rod 4 and the second hook rod 5 ascend along with the first pin 6. The first inclined long hole 41 and the second inclined long hole 51 move upwards and receive the reaction force of the second pin 7, causing the upper ends of the first hook rod 4 and the second hook rod 5 to approach each other. The first hook body 42 and the second hook body 52 retract into the plug middle cavity 31, and the positioning device of the automotive sheet metal part returns to the initial state. Finally, take out the automotive sheet metal part 100 from above the positioning plug 3 of the positioning device.

[0021] The above is only a preferred embodiment of the present invention. Any minor modifications, equivalent changes, and decorations made to the above embodiments based on the technical solution of the present invention are all within the scope of the technical solution of the present invention.
