[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] Example: See Figure 1-4A fixing frame for preventing dents for punching C-type tubes comprises a fixing protrusion 1, the top of the fixing protrusion 1 is C-shaped, a protrusion is fixedly connected to the lower end of the fixing protrusion 1, a waste groove 2 is provided on the protrusion, a slide rail is symmetrically provided inside the waste groove 2, a rectangular threaded sleeve 3 is connected to the bottom of the protrusion, a lifting frame 4 is provided below the protrusion, a rectangular through hole for the rectangular threaded sleeve 3 to pass through is provided on the top of the lifting frame 4, and a bottom plate 5 is fixedly connected to the bottom of the lifting frame 4; a lifting device of the fixing frame is provided inside the lifting frame 4, and the design of the C-shaped fixing protrusion 1 can prevent the C-type tube from being dented by punching; the design of the waste groove 2 can collect the waste generated during punching, thereby preventing the waste from clogging the punching through hole 6.

[0019] In the utility model, the lifting device includes a screw rod 8 which is vertically rotatable and arranged on the inner bottom surface of the lifting frame 4, and a worm wheel 10 which is fixedly sleeved on the bottom of the screw rod 8. A worm 9 is horizontally rotatable in the front end of the lifting frame 4. The worm 9 is meshed with the worm wheel 10 for transmission. One end of the worm 9 is movably extended out of the lifting frame 4 and is fixedly connected with a lifting knob. The rectangular threaded sleeve 3 extends into the interior of the lifting frame 4 through a rectangular through hole. The rod body of the screw rod 8 is connected in the rectangular threaded sleeve 3. By designing the screw rod 8, the worm 9 and the worm wheel 10, the height of the fixed protrusion 1 can be adjusted to adapt to C-type tubes with holes of different heights.

[0020] In the utility model, a punched through hole 6 is provided in the middle of the fixed protrusion 1. The punched through hole 6 is a conical through hole structure that is narrow at the top and wide at the bottom. The bottom of the punched through hole 6 is connected to the waste trough 2. Through the design of the conical punched through hole 6 that is narrow at the top and wide at the bottom, waste can be more easily dropped into the waste trough 2, thereby avoiding clogging of the punched through hole 6 and affecting punching.

[0021] In the utility model, a drawer 7 is provided at the waste trough 2, and sliding grooves are opened on both sides of the drawer 7. The sliding grooves are connected with the slide rails inside the waste trough 2. Through the design of the drawer 7, waste can be collected and stored, thereby avoiding the inconvenience of cleaning after the waste falls into the waste trough 2.

[0022] In the present invention, four fixing holes 11 are respectively formed at four corners of the bottom plate 5 . The fixing frame can be better fixed by the design of the fixing holes 11 on the bottom plate 5 .

[0023] In the utility model, the rectangular threaded sleeve 3 fits with the rectangular through hole on the top of the lifting frame 4. The rectangular threaded sleeve 3 and the rectangular through hole on the top of the lifting frame 4 can prevent the fixed protrusion 1 from rotating and affecting the height adjustment of the fixed protrusion 1.

[0024] Working principle: When the utility model is used, first fix the bottom plate 5 with bolts to align the punching axis with the punching through hole 6, connect the screw rod 8 with the rectangular threaded sleeve 3, then put the drawer 7 into the waste trough 2, and finally adjust the height of the fixed protrusion 1 by the lifting knob to punch the C-shaped round tube. From then on, the use is ended. Under the action of the C-shaped fixed protrusion 1 and the punching through hole 6, the C-shaped tube can be punched to avoid depression, and the waste generated during punching can be collected and stored.
