[0018] The present invention will be described in further detail below with reference to the accompanying drawings.
[0019] As the instruction manual Figure 1 、 2As shown in Figure 4, it includes a fixed clamp body 1 and a movable clamp body 2. A clamp hole selection wheel 3 is provided on one side of the movable clamp body 2. The occlusal surface of the fixed clamp body 1 is provided with a limiting hole 31 corresponding to the clamp hole selection wheel 3. The punching operation is performed by sliding the punching rod above the clamp hole selection wheel 3 and the limiting hole 31 to avoid offset of the punching position of the object during punching.
[0020] An acceleration gear set 4 is provided on one side of the fixed caliper body 1, and an engaging handle 5 is provided at the input end of the acceleration gear set 4. The movable caliper body 2 and the engaging handle 5 are opposite to each other. A positioning plate 11 for fixing the acceleration gear set 4 is provided above the fixed caliper body 1. The acceleration gear set 4 includes an acceleration gear 41 and a driven gear 42 that mesh with each other. The movable caliper body 2 and the engaging handle 5 both pass through the positioning plate 11, the engaging handle 5 passes through the acceleration gear 41, and the movable caliper body 2 passes through the driven gear 42. The engaging handle 5 and the movable caliper body 2 are both connected to the acceleration gear set 4 through a connecting key. The movable caliper body 2 and the driven gear The wheel 42 and the engaging handle 5 are connected to the acceleration gear 41 through a bolt structure. The engaging handle 5 and the acceleration gear 41 as well as the movable caliper body 2 and the driven gear 42 can rotate synchronously through the connecting key. Because the movable caliper body 2 and the engaging handle 5 pass through the internal through hole of the positioning plate 11, and the movable caliper body 2 and the engaging handle 5 are opposite to each other, the engaging handle 5 will not affect the rotation angle of the movable caliper body 2 when rotating. In order to avoid loosening of the sliding connection between the connecting key and the acceleration gear group 4, a screw is used to pass through the side through hole of the acceleration gear 41 and the driven gear 42, and screwed into the internal screw hole of the connecting rod where the connecting key is located for fixation.
[0021] A limit spring 6 is provided between the engaging handle 5 and the side handle of the fixed jaw body 1, which prevents the fixed jaw body 1 and the movable jaw body 2 from over-engaging and facilitates the opening of the jaws; a horn groove 7 for pulling out nails is provided on one side of the fixed jaw body 1, which facilitates the removal of discarded blocks in the items; wire cutters 8 that engage with each other are provided on the sides of the fixed jaw body 1 and the movable jaw body 2, and the wire cutters 8 are located inside the jaw hole selection wheel 3; the wire cutters 8 can be used to trim and shear punched items to make the items more in line with people's requirements.
[0022] As the instruction manual Figure 1 、 3As shown in Figure 4, the clamp hole selection wheel 3 is connected to the side wall of the dynamic clamp body 2 through a positioning bolt 32. A positioning screw 33 passing through the dynamic clamp body 2 is provided on one side of the dynamic clamp body 2. The bottom surface of the clamp hole selection wheel 3 is provided with a plurality of positioning holes 34 corresponding to the positioning screws 33. The positioning screws 33 and the positioning holes 34 as well as the positioning bolts 32 and the center through-hole of the clamp hole selection wheel 3 are all connected by body contact and sliding. The positioning screws 33 and the positioning bolts 32 are both connected to the internal through-hole of the dynamic clamp body 2 through threads. The threaded end of the positioning bolt 32 passes through the center through-hole of the clamp hole selection wheel 3 and is screwed into the dynamic clamp body 2. The clamp body 2 is fixed in the screw hole. Because the connecting end of the positioning bolt 32 and the center through hole of the clamp hole selection wheel 3 is a straight rod, the clamp hole selection wheel 3 can rotate freely around the positioning bolt 32; the positioning screw 33 is screwed into the threaded through hole of the movable clamp body 2, and the straight rod end of the positioning screw 33 slides into the positioning hole 34 for positioning. When the punching rod of the clamp hole selection wheel 3 needs to be replaced, it is only necessary to reverse the positioning screw 33 to separate it from the positioning hole 34, and the clamp hole selection wheel 3 can be freely replaced. Otherwise, the position of the clamp hole selection wheel 3 is locked to avoid rotational deviation of the punching rod selected by the clamp hole selection wheel 3 when punching.
[0023] When the present invention is implemented in a specific manner, according to the punching requirements of the object, a suitable punching rod is selected on the clamp hole selection wheel 3, the positioning screw 33 is flipped, so that the straight rod end of the positioning screw 33 exits the positioning hole 34, the clamp hole selection wheel 3 is rotated, so that the punching rod relative to it is concentric with the limit hole 31, and then the positioning screw 33 is rotated forward so that the straight rod end is stuck in the corresponding positioning hole 34; the engaging handle 5 is lifted, so that the acceleration gear set 4 engages and rotates, thereby controlling the opening of the movable clamp body 2, and the object is stuck between the jaws, and the engaging handle 5 is pressed down so that the punching rod directly below the clamp hole selection wheel 3 passes through the object, completing the punching operation.
[0024] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
