[0033] Please refer to Figures 1-4 The utility model provides a technical scheme: the driving mechanism of one side of outer gear ring 21 includes the driving gear 20 that is engagedly connected to the outside of outer gear ring 21, the inside wall of driving gear 20 is fixedly connected with rotating plate two 35, the bottom of rotating plate two 35 is rotatably connected to the inner wall of the bottom of storage groove one, and the top of rotating plate two 35 is rotatably connected with hollow rod 31, and hollow rod 31 is slidably connected with sleeve rod 36, and the top of sleeve rod 36 is fixedly connected with pedal 30, and hollow rod 31 and sleeve rod 36 are all hollow structures.

[0034] It should be noted that: the driving gear 20 is the input end of the driving clamping mechanism, and the driving mechanism provides power source for the driving gear 20, and due to the structure that the fixed ring two at the bottom of the sleeve rod 36 and the inner arc wall of the hollow rod 31 are narrow at one end and wide at the other end, the sleeve rod 36 cannot be separated from the hollow rod 31.

[0035] Please refer to Figures 1-4 The utility model provides a technical scheme: the outer arc wall of sleeve rod 36 is sleeved with hollow rod 31 away from one end of pedal 30, and hollow rod 31 is fixedly connected to the inner wall of the bottom of storage groove one, and the top inner wall of sleeve rod 36 is fixedly connected with rotating column 32, and the middle part of the inner arc wall of hollow rod 31 is fixedly connected with fixed ring one, and the top of fixed ring one is fixedly connected with reset spring one 34, and the top of reset spring one 34 abuts with screw rod 33, and the top of screw rod 33 is fixedly connected with the rotating column 32 with same structure.

[0037] Please refer to Figures 1-4 The utility model provides a technical scheme: hollow rod 31 bottom rotationally connected with horizontal rotating plate no. 2 35, the end of rotation axis away from rotating plate no. 2 35 is fixedly connected on the bottom inner wall of storage groove no. 1, the top center of rotating plate no. 2 35 is equipped with the spiral chute that vertically penetrates, and the spiral chute is adapted to spiral rod 33, and the middle two ends of the outer lateral wall of spiral rod 33 are fixedly connected with limiting rod, and limiting rod is abutted with reset spring no. 1 34.

[0038] It should be noted that: in the initial state, spiral rod 33 does not contact rotating plate no. 2 35, when the bottom end of spiral rod 33 slides into the spiral chute, since the two rotating columns 32 engage at this time, spiral rod 33 will not rotate and drive rotating plate no. 2 35 to rotate, and limiting rod is convenient for reset spring no. 1 34 to reset spiral rod 33.

[0039] Please refer to Figures 1-4 The utility model provides a technical scheme: the section radius of the top end of the inner arc wall of hollow rod 31 is less than the section radius of the side of the inner arc wall of hollow rod 31 away from sleeve rod 36, sleeve rod 36 bottom fixedly connected with fixed ring no. 2, and fixed ring no. 2 is located in hollow rod 31, and the section radius of the outer arc wall of fixed ring no. 2 is greater than the section radius of the top end of the inner arc wall of hollow rod 31, and the opposite sides of the end of the inner arc wall of hollow rod 31 close to pedal 30 are all equipped with vertical sliding slot no. 4, and the both ends of the outer arc wall of fixed ring no. 2 are all equipped with lug at the position corresponding to sliding slot no. 4, and lug is slidingly connected in sliding slot no. 4, and lug bottom fixedly connected with reset spring no. 2.

[0041] Please refer to Figures 1-4 The utility model provides a technical scheme: support seat 10 top one side fixedly connected with handle 14, and support seat 10 bottom four corners are all installed with self-locking universal wheel.

[0042] It should be noted that: handle 14 and self-locking universal wheel are convenient for operator to use, and self-locking universal wheel belongs to the prior art known and will not be described in detail here.

[0043] Working principle:

[0044] The mold is placed on the top center of the limiting plate 11, and then the foot is stepped on the pedal 30. With the engagement of the two rotating columns 32, the screw rod 33 is prevented from rotating and is driven to descend and engage with the screw chute. Then the screw rod 33 drives the rotating plate two 35 to rotate, the rotating plate two 35 drives the driving gear 20 to rotate, the driving gear 20 in turn engages with the outer tooth ring 21 to rotate, the outer tooth ring 21 drives the ratchet wheel 24 to rotate synchronously to drive the spring to store energy, and the gear column 22 is engaged to rotate to make the plurality of racks 23 slide, thereby making the plurality of sliding plates 12 clamp the mold;

[0045] Due to the length of the screw rod 33, after the pedal 30 is no longer stepped on, the driving mechanism is reset under the action of the reset spring one 34 and the reset spring two. The driving gear 20 cannot rotate due to the engagement of the pawl 25 and the ratchet wheel 24, and the driving gear 20 without power cannot rotate. Therefore, the driving gear 20 cannot rotate at this time, and the rotating plate two 35 cannot rotate. At this time, the pedal 30 is no longer stepped on, and the two rotating columns 32 are no longer engaged. Therefore, the screw rod 33 is reset under the action of the reset spring one 34 and rotates along the screw chute.

[0046] Then only the above steps need to be repeated, that is, after stepping on the pedal 30 for many times, the mold can be clamped step by step. Therefore, it can adapt to clamping of molds of various types and sizes. When the mold needs to be taken out, the pawl 25 is no longer engaged with the ratchet wheel 24 by rotating the rotating plate one 26. At this time, the ratchet wheel 24 is reset under the action of the spring, thereby driving the clamping mechanism to reset. At this time, the screw rod 33 is no longer engaged with the rotating plate two 35, so the driving mechanism will not be affected.
