[0029] Furthermore, threaded holes are provided inside the side wing 48 and outside the connection box 41 , and the bolts 49 are threadedly connected to the inner walls of the threaded holes, so that the side wing 48 can be positioned.

[0030] Furthermore, slots are provided on both sides of the connection box 41 , and dustproof nets are provided at the slots, so as to ensure that the fan 42 generates wind force while reducing the situation where dust affects the operation of the fan 42 .

[0031] Furthermore, through holes are provided at the bottom of the connection box 41 and the top of the punch head 45, and the air duct 44 is connected with the inside of the connection box 41 and the punch head 45 through the through holes, thereby achieving the purpose of hot air transportation.

[0032] Embodiment 2

[0033] See also Figures 1 to 5 On the basis of the first embodiment, the clamping mechanism 5 further comprises a long box 51, the long box 51 is fixedly connected to the bottom of the connecting plate 3, a spring 52 is fixedly connected to the inner wall of the long box 51, a moving plate 53 is fixedly connected to the bottom end of the spring 52, a connecting shaft 54 ​​is fixedly connected to the bottom of the moving plate 53, and a pressing plate 55 is fixedly connected to the bottom end of the connecting shaft 54, so as to play the role of clamping and limiting the automobile parts.

[0034] Furthermore, the movable plate 53 is slidably connected to the inner wall of the long box 51, so that the movable plate 53 can move stably.

[0035] Furthermore, a circular hole is provided at the bottom of the long box 51 , and the connecting shaft 54 ​​passes through the circular hole, so that the connecting shaft 54 ​​can move through the circular hole.

[0036] In actual operation, when this device is used, the staff first places the parts to be processed on the inner bottom of the frame 1, and then the fan 42 and the heating tube 43 can be started.
