The transmission stability of the cross bar 5 is improved by moving the two transmission mechanisms 4 at the same time.

[0028] Please refer to Figure 2 and Figure 3 The transmission mechanism 4 includes a lifting rod 41 fixedly connected to the bottom of the lifting plate 2 and a positioning block 46 fixedly connected to one side of the support frame 1. The bottom end of the lifting rod 41 passes through the positioning block 46 and is fixedly connected to the moving shaft 42.

[0029] The transmission mechanism 4 further comprises a transmission plate 43 rotatably connected to a side surface of the support frame 1 . A first moving groove 44 is formed at one end of the transmission plate 43 close to the moving shaft 42 . The moving shaft 42 is slidably connected inside the first moving groove 44 .

[0030] A second moving groove 45 is formed at one end of the transmission plate 43 close to the cross bar 5 . The first moving groove 44 and the second moving groove 45 are symmetrically distributed at both ends of the transmission plate 43 . One end of the cross bar 5 is slidably connected to the inside of the second moving groove 45 .

[0031] In the above scheme, when the lifting plate 2 moves downward, it drives the lifting rod 41 to move, and the lifting rod 41 drives the transmission plate 43 to rotate on the outer surface of the support frame 1, and then the transmission plate 43 drives the cross bar 5 to move outside the support frame 1.

[0032] Please refer to Figure 1 and Figure 2 Two positioning rods 10 are slidably connected to the upper surface of the support frame 1, a processing contact 9 is placed between the two positioning rods 10, and a positioning mechanism 6 for driving the positioning rods 10 to move is provided on one side of the support frame 1.

[0033] Please refer to Figure 2 and Figure 4 The positioning mechanism 6 includes positioning sleeves 67 fixedly connected to both sides of the bottom of the support frame 1, the outer surfaces of the two positioning sleeves 67 are rotatably connected to the second connecting rods 66, and the bottom ends of the two second connecting rods 66 are rotatably connected to the moving sleeves 63.

[0034] The positioning mechanism 6 also includes a push rod 61 fixedly connected to the middle section of the cross bar 5 , the top of the push rod 61 is fixedly connected to a moving rod 62 , and both ends of the moving rod 62 respectively penetrate two moving sleeves 63 and extend to the outside of the moving sleeves 63 .

[0035] The side of the movable sleeve 63 away from the second connecting rod 66 is rotatably connected to the first connecting rod 64, and the top of the first connecting rod 64 is fixedly connected to the sliding rod 65.

[0037] In this embodiment, when the riveting device is used, the processing contact 9 is placed in the middle of the upper surface of the support frame 1. When the lifting plate 2 is triggered by external power to drive the punch head 3 to move downward for punching, the punch head 3 drives the transmission mechanism 4 to move, and the transmission mechanism 4 drives the positioning mechanism 6 to move through the cross bar 5, and then the positioning mechanism 6 drives the positioning rod 10 to position the processing contact 9;
