[0033] Example 2

[0034] Reference Figures 2 to 5, which is the second embodiment of the present utility model, and this embodiment is based on the previous embodiment.

[0035] Specifically, a limiting strip 202a is provided at the bottom of the closing door 201a, and a limiting block 202b is provided below the fixing block 201d.

[0036] The limiting strip 202a is set as an inclined plane, and the limiting block 202b is set as an inclined plane. When the closing door 201a is closed, the limiting block 202b will squeeze the limiting strip 202a to make it move. After the closing door 201a is closed, the limiting strip 202a will separate from the limiting block 202b. At this time, the limiting strip 202a will return to its original position, and then the setting of the limiting block 202b will limit the closing door 201a to prevent the closing door 201a from opening by itself.

[0037] Specifically, a support frame 202c is sleeved outside the limiting strip 202a. The support frame 202c is movably connected to the limiting strip 202a, and the support frame 202c is fixed to the bottom of the closing door 201a.

[0038] The support frame 202c is used to support the limiting strip 202a to prevent the limiting strip 202a from shifting during movement.

[0039] Specifically, a first spring 202d is fixed at one end of the limiting strip 202a, and the first spring 202d is fixed to the inner wall of the support frame 202c.

[0040] When the limiting strip 202a moves, it can exert a squeezing force on the first spring 202d. After the limiting strip 202a separates from the limiting block 202b, the first spring 202d can drive the limiting strip 202a to return to its original position by the rebounding force.

[0041] Specifically, a pull rope 202e is fixed to one side of the limiting strip 202a. A pull ring 202f is fixed at one end of the pull rope 202e. The pull rope 202e is inserted into one side of the closing door 201a, and the pull ring 202f is movably connected to the pull rope 202e.

[0042] When it is necessary to open the closing door 201a, by pulling the pull ring 202f, the pull ring 202f can drive the pull rope 202e to move. The movement of the pull rope 202e will drive the limiting strip 202a to separate from one side of the limiting block 202b, and then the limit on the closing door 201a can be released to open it.

[0043] Specifically, a support wheel 202g is provided at the bottom of the pull rope 202e. A connecting block 202h is provided on one side of the support wheel 202g. The support wheel 202g and the connecting block 202h are rotationally connected through a rotating shaft, and the connecting block 202h is fixed to one side of the support frame 202c.

[0044] The support wheel 202g is used to support the pull rope 202e to prevent the pull rope 202e from shifting. The support wheel 202g can be supported by setting the connecting block 202h.

[0045] Specifically, a positioning column 302a is fixed on one side of the positioning block 301c. A positioning sleeve 302b is sleeved outside the positioning column 302a, and the positioning column 302a and the positioning sleeve 302b are movably connected.

[0046] When the closing door 201a is moved forcefully, it can drive the positioning disk 301b to rotate. At this time, the positioning groove on the positioning disk 301b will squeeze the positioning block 301c, so that the positioning block 301c is engaged with the next positioning groove. The positioning column 302a can support the positioning block 301c to prevent the positioning block 301c from shifting. The positioning sleeve 302b is used to support the positioning column 302a.

[0047] Embodiment 3

[0048] Refer to Figures 1 to 5 , which is the third embodiment of the present utility model. This embodiment is based on the first two embodiments.

[0049] Specifically, a moving disk 302c is sleeved outside the positioning column 302a, and a second spring 302d is fixed on one side of the moving disk 302c.

[0050] When the positioning column 302a moves, it can drive the moving disk 302c to move. By moving the moving disk 302c, a squeezing force will be applied to the second spring 302d. When the positioning block 301c is moved to one side of the next positioning groove, the elastic force of the second spring 302d can drive the positioning block 301c to engage with the next positioning groove. By repeating this process, the closing door 201a can be stopped at any position.

[0051] Specifically, a connecting column 302e is fixed at one end of the positioning column 302a, and a positioning plate 302f is sleeved outside the positioning sleeve 302b.

[0052] The connecting column 302e can limit the positioning column 302a to prevent the positioning column 302a from moving excessively and falling off the positioning sleeve 302b. The positioning plate 302f is fixed on one side of the punching machine frame 101. By setting the positioning plate 302f, the positioning sleeve 302b can be supported.

[0053] Specifically, it further includes a main body assembly 100, which is arranged on one side of the closing door 201a and includes a punching machine frame 101 and a support leg 102. The punching machine frame 101 is hinged to one side of the closing door 201a, and the support leg 102 is fixed to the bottom of the punching machine frame 101.

[0054] The punching machine frame 101 is the main structural framework part of the punching machine. The punching machine frame 101 plays a role in supporting and fixing various components of the punching machine. The number of support legs 102 is two, and they are both fixed to the bottom of the punching machine frame 101. The support legs 102 are used to support the components of the entire punching machine. The support legs 102 lift the punching machine frame 101 and the entire punching machine equipment off the ground, so that the punching machine is at an appropriate working height, facilitating operation and maintenance by the operator.

[0055] When in use, when it is necessary to move the closing door 201a, first, the limit on the closing door 201a needs to be released. By pulling the pull ring 202f, the pull ring 202f can drive the pull rope 202e to move. The movement of the pull rope 202e will drive the limit bar 202a to separate from one side of the limit block 202b, thereby releasing the limit on the closing door 201a. Then, forcefully move the closing door 201a to open it. When the closing door 201a moves, it can drive the sliding rod 201b to move inside the support rod 201c, thereby supporting the closing door 201a and preventing the closing door 201a from shifting during movement.

[0056] When forcefully moving the closing door 201a, it can drive the rotating shaft 301a to rotate. The rotation of the rotating shaft 301a drives the positioning disk 301b to rotate. At this time, the positioning groove on the positioning disk 301b will squeeze the positioning block 301c to make it move. When the positioning post 302a moves, it can drive the moving disk 302c to move. The movement of the moving disk 302c will exert a squeezing force on the second spring 302d. When the positioning block 301c moves to one side of the next positioning groove, the elastic force of the second spring 302d can drive the positioning block 301c to engage with the next positioning groove. By repeating this process, the closing door 201a can be stopped at any position.

[0057] When closing the closing door 201a, the inclined surface on the limit block 202b will squeeze the limit bar 202a to make it move. When the limit bar 202a moves, it can exert a squeezing force on the first spring 202d. After the limit bar 202a separates from the inclined surface on the limit block 202b, the elastic force of the first spring 202d can drive the limit bar 202a to return to its original position, thereby limiting the closing door 201a.

[0058] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not restrictive. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
