The cutter 17 normally closes the paper outlet 20, the cutter 17 is autonomously controlled by a doctor to give way when the doctor intercepts the occlusion paper 4, and the occlusion paper 4 at the paper outlet 20 is cut off by rapidly rebounding and resetting after the interception length is determined. The elastic pedal is connected with the cutter 17 through the cutter pulling rope 8, so that a doctor can press the elastic pedal to realize the abdication paper outlet 20 of the cutter 17 and drive the cutter 17 to reset quickly to cut off the occluding paper 4. The following describes the case 5 and the elastic pedal in this embodiment, respectively:

as shown in fig. 1, the box 5 is rectangular, the paper outlet 20 is disposed at the bottom of the right side wall of the box 5, the bottom of the box 5 is fixed on the console 2 of the oral cavity doctor by a bolt or a buckle structure, and the right paper outlet 20 is distributed toward the doctor, so that the doctor can take the bite paper 4 at any time. The box walls at the front side and the rear side of the inner cavity of the box body 5 are respectively provided with corresponding rotary supporting seats (not shown in the figure), and a horizontal shaft 7 distributed along the horizontal direction is installed in the two rotary supporting seats in a matching way. The horizontal shaft 7 is coaxially connected with a roller 6 through a positioning key, and the outer edge of the roller 6 is provided with a clamping groove, so that one end of the continuous strip-shaped occluding paper 4 is fixed on the roller 6 through the clamping groove, and the other end of the continuous strip-shaped occluding paper is continuously wound on the roller 6 in the same direction and then extends out of the paper outlet 20. When taking the occluding paper 4, a doctor can clamp the free end of the occluding paper 4 through medical forceps after the cutter 17 gives way, and the occluding paper 4 with a specific length is conveniently pulled out through the matching of the horizontal shaft 7 and the rotary supporting seat. In this embodiment, a guide wheel 3 is disposed at a position close to the paper exit 20, and a lower edge of the guide wheel 3 is flush with the paper exit 20 and is in rolling fit with an upper edge of the occluding paper 4 at the paper exit 20, so that the occluding paper 4 at the paper exit 20 is in a horizontal state no matter how thick the occluding paper 4 is on the reel, thereby preventing the occluding paper 4 from being scratched on the side wall of the box 5 at the paper exit 20, and facilitating the cutting of the occluding paper 4 by the cutter 17.

The right side wall of the box body 5 is thicker and is provided with a cavity 49, and the bottom of the cavity 49 divides the paper outlet 20 into two parts. The right wall portion of the box 5 is inwardly folded in an L-shape toward the cavity 49 to form a paper-taking slot 50 at the lower right corner of the right side wall of the box 5. The cutters 17 are vertically slidably arranged, and cutting edges of the cutters 17 are wedge-shaped and located at the lower ends of the cutters 17, so that the occluded paper 4 at the paper outlet 20 is cut off in the process that the cutters 17 rapidly move downwards. The two sides of the cutter 17 are in sliding fit with the two cutter grooves 13 arranged on the outermost side of the side wall of the right side of the box body 5, and the cutter grooves 13 are in smooth fit with the side parts of the cutter 17, so that the phenomenon of jamming is avoided. In the embodiment, the notch of the paper taking groove 50 is closed by the cutter 17 under a normal state (the lower cutting edge of the cutter 17 is inserted into the slot 21 arranged at the bottom position of the right side of the paper taking groove 50 to completely close the cutter 17 groove 13 and avoid adverse effects caused by the wedge-shaped cutting edge at the lower end of the cutter 17), and after the occluding paper 4 is cut off by the cutter 17, a new free end on the occluding paper 4 is accommodated in the paper taking groove 50, the free end of the occluding paper 4 is prevented from being polluted by the closing action of the cutter 17, and doctors can conveniently stretch the tweezers into the paper taking groove 50 to take paper repeatedly.

The top of the cutter 17 is fixedly connected with the cutter holder 14 arranged in the cavity 49 through a rivet 15, the right side wall of the box body 5 is also provided with strip-shaped holes 12 which are distributed in parallel with the cutter grooves 13, and the right end of the cutter holder 14, which is provided with the strip-shaped holes 12, extends out of the cavity 49 to be fixedly connected with the cutter 17. The knife holder 14 is fixedly connected with the knife pulling rope 8, so that a doctor steps on the pedal to drive the knife holder 14 to vertically ascend, and the knife holder 14 drives the cutter 17 to vertically ascend, so that the yielding paper outlet 20 is realized. In this embodiment, in order to adapt to current department of stomatology so that operation panel 2, the doctor of being convenient for gets paper, perforation 1 has been seted up specially on operation panel 2, to penetrate box 5 (the hole that corresponds the box 5 bottom not shown) by this perforation 1 by the broach rope 8 that stretches out by the elasticity footboard, it is fixed with blade holder 14 again to make broach rope 8 walk around setting behind two fixed pulleys 9 of cavity 49 top interval distribution, thereby do not occupy extra space, and easily walk the line, make operation panel 2 overall arrangement more reasonable. The top of the cavity 49 is provided with a clapboard 10 which separates the fixed pulley 9 from the rest of the cavity 49, and the clapboard 10 is provided with a hole for the broach rope 8 to pass through. A paper cutting linear spring 11 is arranged between the partition board 10 and the cutter holder 14, and the upper and lower ends of the paper cutting linear spring 11 are respectively fixedly connected with the partition board 10 and the cutter holder 14, so that the paper cutting linear spring 11 is compressed in the process of pulling the cutter 17 to rise through the pull cord 8, and the cutter 17 moves downwards under the elastic force of the paper cutting linear spring 11 in a compressed state after the pulling force of the pull cord 8 disappears, and then the bite paper 4 is cut off by the lower cutting edge.

In order to prevent the free end of the cut bite paper 4 from being curled inward toward the inner wall of the casing 5 by the tension after the cutter 17 moves down the cut paper. In this embodiment, a pressing head 19 is provided at the bottom of the cavity 49 to be engaged with the cutter 17 and to press and fix the free end of the engagement paper 4 to the bottom of the cavity 49 during the paper cutting process. The pressing head 19 is made of medical silica gel material, the lower edge of the pressing head is used for pressing and fixing the occluding paper 4, the upper end of the pressing head is provided with a rigid base 18, the base 18 is connected with the tool apron 14, so that the pressing head 19 can move upwards to relieve the pressure on the free end of the occluding paper 4 in the process that the tool apron 14 is pulled by the broach rope 8 to move upwards, and a doctor can pull the occluding paper 4 freely. Since the lower edge of the pressing head 19 is flush with the paper outlet 20 and is higher than the lower edge of the cutting knife 17 in the embodiment, in order to ensure that the cutting knife 17 can slide through the paper outlet 20 to cut paper in the state that the pressing head 19 presses and fixes the engaged paper 4 in the downward moving process, the base 18 and the knife holder 14 in the embodiment are also partially provided with the compression spring 16. The compression spring 16 is vertically distributed, and both ends of the compression spring are fixed to the holder 14 and the base 18, respectively, and the compression spring 16 is in a compressed state in the state shown in fig. 1. The length and degree of compression of the compression spring 16 are such that when the tool holder 14 is raised to the point where the lower end of the cutting blade 17 passes over the paper outlet 20 by pulling the pull-cord 8 downwards, as shown in fig. 2, the compression spring 16 is in a compressed state and at the limit of natural elongation or still in a compressed state, so that the height of the lower edge of the cutting blade 17 is higher than that of the lower edge of the pressure head 19. After the broach rope 8 is continuously pulled down, the cutter 17 further rises, the compression spring 16 is completely restored, the pressure head 19 and the cutter 17 keep synchronous rising after the compression spring 16 is restored, and the lower end of the cutter 17 is higher than the lower edge of the pressure head 19 in the rising process. With the arrangement, the pressing head 19 firstly contacts the occluding paper 4 and tightly presses the occluding paper 4 at the bottom of the cavity 49 in the process that the cutter holder 14 is pushed down by the paper cutting linear spring 11 after the tension of the cutter pulling rope 8 disappears, then the lower end of the cutter 17 slides over the occluding paper 4, and the occluding paper 4 is cut off under the state that the occluding paper 4 is fixed by the pressing head 19. The base 18 in this embodiment is also slidably engaged with the inward-folded L-shaped inner wall of the right side of the box 5 by a wire-rail structure (not shown), so as to prevent the pressing head 19 from slipping or being locked.

The elastic pedal in the embodiment is arranged on the ground below the operating platform 2, so that a doctor can conveniently step on the elastic pedal in the oral cavity correction process. As shown in fig. 4, the elastic step in this embodiment includes a base 30 fixed to the bottom surface, and a step 25 and a vertical strut 27 provided on the base 30. The pedal 25 is rectangular and horizontally distributed, the left end of the pedal is fixedly provided with a rotating shaft 23 distributed along the width direction of the pedal, and the two ends of the rotating shaft 23 are connected with the shaft seat 22 fixed at the left end position of the base 30, so that the pedal 25 is hinged with the base 30. A return torsion spring 24 is further provided on the rotation shaft 23, and one end thereof is connected to the pedal 25 and the other end thereof is connected to the base 30 to maintain the initial state of the pedal 25 as shown in fig. 1 by the return torsion spring 24. The vertical sliding column 27 is vertically inserted and fixed at the right end of the base 30, the free end of the pedal 25 is provided with positioning grooves 26 longitudinally distributed along the pedal, and the positioning grooves 26 are clamped at the periphery of the vertical sliding column 27 and are in sliding fit with the vertical sliding column 27. A slide block 28 is arranged on the vertical slide column 27 below the free end of the pedal 25 in a sliding manner, and a return spring 29 is sleeved on the vertical slide column 27 between the slide block 28 and the base 30, so that the slide block 28 can move downwards along with the stepping of the pedal 25 by a doctor and compress the return spring 29 as shown in fig. 5, and can be quickly reset to the state shown in fig. 4 through the elastic action of the return spring 29 and the return torsion spring 24 after the stepping action of the doctor disappears. The end of the aforementioned knife pulling rope 8 far from the knife seat 14 is fixed on the slide block 28, so that the doctor presses the pedal 25 to move the knife seat 14 up synchronously, and the knife 17 and the pressure head 19 are pulled up by the knife seat 14.

The implementation process of this embodiment is as follows:

in the initial state of fig. 1 and 4, when the doctor needs to take out the bite paper 4, he presses the pedal 25, and the slide 28 is pressed by the free end of the pedal 25 to move down to the state shown in fig. 5. In the process, the knife holder 14 is synchronously pulled to rise by the knife pulling rope 8 along with the pressing of the free end of the pedal 25. When the knife holder 14 is lifted up as shown in fig. 2, the cutting knife 17 is lifted up synchronously with the knife holder 14 and passes through the paper outlet 20, and the pressing head 19 is stationary due to the action of the compression spring 16, and the compression spring 16 is restored to the natural length. As shown in fig. 3, as the pedal 25 is continuously pressed down, the pressing head 19 and the cutting knife 17 are synchronously lifted along with the knife holder 14, the paper taking groove 50 is sufficiently exposed, and a doctor can clamp and fix the free end of the bite paper 4 by using forceps and pull out the bite paper 4 by a specific length according to the required length.

After the physician pulls out the occluding paper 4 by a certain length, the pedal 25 can be quickly released, and the pedal 25 is quickly reset under the action of the reset torsion spring 24 and the reset spring 29, so that the pulling force of the broach rope 8 on the tool apron 14 disappears. At this time, the knife holder 14 is rapidly moved downwards under the action of the paper cutting linear spring 11, in the process, the pressing head 19 firstly contacts the occlusal paper 4 and presses and fixes the occlusal paper 4 at the bottom of the cavity 49, the lower end of the cutting knife 17 then slides through the paper outlet 20, and the occlusal paper 4 is cut off through the cutting edge, so that a doctor can take out the cut occlusal paper 4 from the paper taking groove 50 for occlusion and fitting of teeth. Finally, the lower end of the cutter 17 is inserted into the slot 21 to close the paper taking groove 50. The free end of the occluding paper 4 partially extends out of the paper outlet 20 and is positioned in the paper taking groove 50 for holding and fixing next time when the doctor takes the paper.

It should be noted that, in this embodiment, if the doctor slowly releases the pedal 25, the cutter 17 also slowly moves down, and the kinetic energy of the cutter 17 may not cut off the occlusion paper 4, so that the doctor needs to quickly release the pedal 25 to reset. Specifically, when the doctor steps on the step piece 25, only a part of the sole of the foot presses the step piece 25. When the pedal 25 is released, the sole is rotated around the ankle without changing the height of the sole, so that the sole is separated from the pedal 25, the treading pressure provided by the sole disappears instantly, the pedal 25, namely the sliding block 28, resets rapidly, the tension of the broach rope 8 disappears instantly, the effect of rebounding the cutter 17 rapidly is achieved, and the cutting effect of the cutter 17 on the occlusion paper 4 is ensured.

Example 2

The structure of the case 5 in this embodiment is the same as that in embodiment 1, except that a reset type quick release mechanism is integrated with the elastic pedal in this embodiment. Through the quick release mechanism of formula that resets, make the doctor cancel 8 pulling forces of broach rope so that the in-process that cutter 17 popped out fast, need not the accurate operation that the doctor adopted aforementioned complicated rotation ankle, the doctor can step on in pedal 25 by the full sole to even after the sole slowly lifts and slowly releases pedal 25 return, still can cancel 8 pulling forces of broach rope rapidly, improve doctor's operating comfort and ensure pulling force release effect.

As shown in fig. 6, the reset quick release mechanism includes a sliding mandrel 31, a fixed sleeve 33, a clutch sleeve 37 and a sprocket 39, which are horizontally concentrically arranged. The chain wheel 39 is used for controlling the tension of the broach rope 8 on the tool apron 14 by controlling the displacement of the broach rope 8, and the effect of instantly canceling the tension of the broach rope 8 on the tool apron 14 is achieved by locking/unlocking the rotation direction of the chain wheel 39. The sprocket 39 has a wheel body and a support body penetrating the center of the wheel body, and the support body is cylindrical and has both ends supported by bearings 40. The outer edge of the wheel body is provided with evenly spaced and continuously distributed sprockets, the broach rope 8 is provided with a chain section 801 which is matched and installed on the sprockets, two ends of the broach rope 8, which are located on the chain section 801, are respectively pressed tightly through conventional pressing wheels (not shown in the figure) so as to ensure that the chain section 801 and the teeth of the chain wheel 39 are in a splicing matching state, and therefore the movement of the broach rope 8 is controlled through the rotating state of the chain wheel 39. The rotation state of the chain wheel 39 is controlled by the sliding mandrel 31, the fixed sleeve 33, the clutch sleeve 37 and the elastic pedal, specifically:

The sliding core shaft 31 has a rectangular shaft body on the left side of the annular protrusion 35, and the fixed sleeve 33 has a corresponding rectangular inner hole, so that the sliding core shaft 31 can only move in the circumferential direction under the action of external force and cannot rotate. A release spring 34 is provided on the slide core shaft 31 between the annular projection 35 and the fixed sleeve 33, and both ends of the release spring 34 are fixedly connected to the fixed sleeve 33 and the annular projection 35, respectively.

The right end of the sliding mandrel 31 is slidably and rotatably sleeved in the central hole of the chain wheel 39, and the clutch sleeve 37 is slidably arranged on the sliding mandrel 31 at a position between the annular protrusion 35 and the chain wheel 39. In order to achieve the sliding fit and rotation fit effects, the right shaft body of the sliding mandrel 31 is circular, the central holes of the supporting body of the chain wheel 39 and the clutch sleeve 37 are correspondingly circular, sliding grooves distributed along the longitudinal direction are formed in the right shaft body of the sliding mandrel 31, a sliding strip in sliding fit with a key groove is arranged on the inner wall of the central hole of the clutch sleeve 37, and no sliding strip is arranged in the central hole of the chain wheel 39, so that the clutch sleeve 37 cannot rotate relative to the sliding mandrel 31 and the chain wheel 39 can rotate freely on the basis of ensuring that the chain wheel 39 and the clutch sleeve 37 can slide freely along the sliding mandrel 31. An abdicating spring 36 is arranged between the annular bulge 35 and the clutch sleeve 37 on the sliding mandrel 31, and two ends of the abdicating spring 36 are respectively fixedly connected with the annular bulge 35 and the clutch sleeve 37. As shown in fig. 6 and 7, the opposite surfaces of the clutch sleeve 37 and the sprocket 39 are respectively provided with corresponding ratchet teeth 38, and the ratchet teeth 38 are wedge-shaped, one side is an inclined surface, and the other side is a straight surface. In the state of the engagement of the pair of ratchet teeth 38 shown in fig. 7, the sprocket 39 is rotated clockwise continuously by engaging the inclined surfaces of the ratchet teeth 38 to left-shift the clutch sleeve 37; when the sprocket 39 rotates counterclockwise, the pair of ratchet teeth 38 are pushed against each other so that the sprocket 39 cannot rotate in one direction.

The main structure of the elastic pedal in this embodiment is the same as that of embodiment 1, except that: the slide 28 of this embodiment is further fixedly provided with a pull cord 41 for driving the slide spindle 31 to move. One end of a pull shaft rope 41 is fixed with the slide block 28, and the other end of the pull shaft rope penetrates through the center hole of the right side of the chain wheel 39 and then is fixedly connected with the right end of the sliding core shaft 31, so that the sliding core shaft 31 can be synchronously pulled to move to the right when a doctor steps on the pedal, the release spring 34 is stretched, and the abdicating spring 36 is compressed. The specific implementation process of this embodiment is as follows:

fig. 6 shows the initial state of the resilient pedal and the reset quick release mechanism of the present embodiment, in which the release spring 34 and the abdicating spring 36 are both naturally extended, and the clutch sleeve 37 and the ratchet 38 on the sprocket 39 approach each other and separate from each other. In the process that the doctor steps on the pedal 25 to clamp the occluding paper 4, the sliding mandrel 31 is pulled to move rightwards by the pulling mandrel rope 41 at the initial stage of downward movement of the free end of the pedal 25, and the clutch sleeve 37 and the ratchet 38 on the chain wheel 39 are meshed with each other to realize unidirectional locking. Meanwhile, the pulling rope 8 transmits the pulling force to the tool holder 14 through the chain wheel 39 to drive the tool holder 14 to ascend, and the chain wheel 39 rotates due to the cooperation with the chain section 801. Then, after the clutch sleeve 37 and the sprocket wheel 39 are engaged by the ratchet 38, as the pedaling continues, the sprocket wheel 39 generates a continuous rotation trend under the pulling force of the pull cord 8 between the sprocket wheel 39 and the slider 28, and the rotation trend enables the sprocket wheel 39 to continuously discharge the clutch sleeve 37 to the left to maintain the continuous rotation of the sprocket wheel 39 (i.e. the clutch sleeve 37 automatically reciprocates between the engaged state and the disengaged state with the sprocket wheel 39 under the combined action of the leftward pushing action of the sprocket wheel 39 and the rightward pushing action of the abdicating spring 36). The chain wheel 39 which continuously rotates normally transmits the driving action of the broach rope 8 on the tool apron 14, so that the chain wheel 39 continuously rotates to transmit the tension of the broach rope 8, the tool apron 14 is continuously driven to ascend, and the effects of cutter 17 abdicating and pressure head 19 separating are achieved.

When the pedal 25 shown in fig. 8 is stepped to the bottom, the case 5 in this embodiment also reaches the state shown in fig. 3 in embodiment 1, and the doctor can pull out the free end of the bite paper 4 to an appropriate length by using forceps. The physician may then follow the habit of controlling the natural and slow lifting of the sole off the pedal 25. In the process that the sole lifts off the pedal 25, the pulling force generated by the pull shaft rope 41 and the pull cutter rope 8 is continuously reduced, wherein the pull shaft rope 41 is still in a tight state, so that the sliding core shaft 31 moves left under the action of the pulling force of the release spring 34 under the condition that the pulling force provided by the pull shaft rope 41 is gradually reduced. The part of the pull-cutter rope 8 between the chain wheel 39 and the cutter seat 14 is still in a tight state because the chain wheel 39 cannot rotate reversely, and the pushing force of the paper cutting linear spring 11 is continuously offset to make the cutter seat 14 static; the portion of the pull-cord 8 between the sprocket 39 and the slider 28 becomes gradually slack. As the pedaling action slowly disappears, the pedal 25 is gradually returned to the non-pedaling state by the thrust of the return torsion springs 24 and 29, and then the springs are naturally extended to separate the clutch sleeve 37 from the sprocket 39. At the moment when the clutch sleeve 37 is separated from the chain wheel 39, the chain wheel 39 is released from the unidirectional locking due to the separation of the paired engaged ratchets 38, so that the ratchet wheel can rotate freely, the tension of the chain wheel 39 on the section of the ratchet wheel-knife seat 14 on the pull-cord 8 is automatically eliminated, and finally the knife seat 14 can move downwards rapidly under the action of the paper cutting linear spring 11 and cut the engaged paper 4. And the chain wheel 39 is synchronously pulled to rotate reversely in the process that the paper cutting linear spring 11 pushes the tool apron 14 to move downwards, so that the slack part on the pull-cutter rope 8 is compensated between the chain wheel 39 and the tool apron 14, and all parts of the elastic pedal and the reset type quick release mechanism are completely restored to the initial state shown in fig. 6.

The elastic pedal is treaded by a doctor, the doctor does not need to adopt the complex accurate operation of rotating the ankle mentioned in the embodiment 1 in the process of canceling the pulling force of the broach rope 8 to enable the cutter 17 to pop up quickly by the treading type quick release mechanism, the doctor can tread the pedal sheet 25 with the full sole to enable the cutter 17 and the pressure head 19 to give way and pull out the occluding paper 4, and continuously and deeply treading the elastic pedal after pulling out to cancel the pulling force of the broach rope 8 instantly to realize paper cutting, and the effects of improving the operation comfort of the doctor and guaranteeing the pulling force release, which are the same as those of the embodiment 2, are achieved.

As shown in fig. 9-11, the resilient pedal-pressing quick release mechanism assembly in this embodiment includes a rectangular base 30 fixed on the horizontal ground under the console 2, a pedal 25 hinged to the left end of the base 30, and a vertical sliding column 27 and a guide column 43 fixedly inserted to the right end of the base 30.

The vertical sliding column 27 is sequentially provided with an upper limiting block 45, a sliding block 28 and a return spring 29 from top to bottom. The slide block 28 is arranged on the vertical sliding column 27 in a sliding mode, the broach rope 8 in the box body 5 is still fixed on the slide block 28 after penetrating out of the operating platform 2, the upper limiting block 45 is fixed on the vertical sliding column 27, and the return spring 29 enables the slide block 28 to be pushed against the lower edge of the upper limiting block 45 under the natural length. The guide post 43 is arranged on one side of the vertical sliding post 27 at intervals along the width direction of the base 30, the main body of the guide post 43 is in an S shape, and the main body of the guide post 43 is provided with a first vertical section 4301 which is located above and closer to the vertical sliding post 27, a second vertical section 4303 which is located below and farther from the vertical sliding post 27, and an arc section 4302 which connects the first vertical section 4301 and the second vertical section 4303, wherein the second vertical section 4303 is spliced and fixed on the base 30.

The left end of the base 30 is provided with a turntable 42 for the pedal 25 to be hinged and installed, the turntable 42 is cylindrical and is vertically distributed, and the rotation direction of the turntable is along the central line direction of the turntable. The turntable 42 is provided with a shaft seat 22, the left end of the pedal 25 is provided with a rotating shaft 23 which is rotatably matched with the shaft seat 22 to realize hinged connection, and the rotating shaft 23 is provided with a reset torsion spring 24 which maintains the right end of the pedal to tilt the turntable 42. The constant head tank 26 along self longitudinal distribution is seted up to the right end of pedal 25, and this constant head tank 26 joint is on first vertical section 4301 under the effect of reset torsion spring 24 and reset spring 29 under natural state, and pedal 25 accessible constant head tank 26 slides to segmental arc 4302 with first vertical section 4301's sliding fit under the state of stepping on to run through segmental arc 4302 and slide in second vertical section 4303 under the rotation support assistance of revolving stage 42. The positioning slot 26 is rounded on both sides to fit slidably with each portion of the guide post 43. A pushing part 47 is formed on one side of the free end of the pedal 25 close to the vertical sliding column 27, a reversible bearing platform 44 is hinged on one side of the slide block 28 facing the pedal 25, and in an initial state, the reversible bearing platform 44 is positioned right below the pushing part 47, so that when the pedal 25 is pressed to move downwards, the reversible bearing platform 44 is pushed by the pushing part 47 to move downwards, the slide block 28 is driven to move downwards, and the tool apron 14 is pulled to move upwards by the tool apron rope 8.

The reversible platform 44 is a rectangular rigid plate of the same thickness as the slider 28, as shown in fig. 10, with the right side of the reversible platform 44 aligned with the left side of the slider 28, and the upper edge of the reversible platform 44 hinged to the upper portion of the slider 28 by a hinge 46. When the reversible bearing table 44 is pressed from top to bottom (the pushing part 47), the slider 28 is driven to move downwards, and when the reversible bearing table 44 is pushed from bottom to top, the pushing force pushes the reversible bearing table 44 to rotate clockwise around the hinge 46, so that the slider 28 cannot be driven to move upwards.

The specific implementation process of this embodiment is as follows:

in the initial state shown in fig. 9 to 11, when the doctor steps on the pedal 25, the pedal 25 moves downward and presses the reversible platform 44 by the pressing portion 47, the slider 28 is moved downward by the reversible platform 44, and finally, as shown in fig. 3 of embodiment 1, the cutter 17 and the pressed piece are pulled by the pull string 8 to the paper outlet 20 and the bite paper 4, respectively. The paper taking groove 50 is sufficiently exposed, and the doctor can hold and fix the free end of the bite paper 4 by using forceps and pull out the bite paper 4 by a certain length according to the required length. Positioning slot 26 at the free end of pedal 25 is located at first vertical segment 4301 of guide column 43 or at the junction of first vertical segment 4301 and arc segment 4302.

After the doctor pulls out the bite paper 4 with a specific length, the doctor continuously presses the pedal 25, under the rotating matching action between the rotary table 42 and the pedal 25 and the guiding action of the guide column 43 on the positioning groove 26, the positioning groove 26 at the free end of the pedal 25 slides into the second vertical section 4303 through the arc-shaped section 4302, the pushing part 47 is immediately separated from the reversible bearing platform 44, the downward pressure on the sliding block 28 disappears instantly, namely the sliding block rebounds to the lower limit block rapidly under the action of the return spring 29, so that the pulling force of the broach rope 8 disappears instantly, the knife holder 14 rapidly moves downwards under the pushing force of the paper cutting linear spring 11, and the pressing head 19 and the cutter 17 are pushed to respectively press and fix the bite paper 4 and cut off the bite paper 4 at the paper outlet 20.

Subsequently, the physician lifts the sole of the foot away from the pedal 25, the pedal 25 rebounds under the action of the reset torsion spring 24, and the free end of the pedal 25 slides into the first vertical section 4301 again to reach the initial state through the guiding fit of the positioning slot 26 and the arc section 4302. During the period, when the pedal 25 passes through the reversible bearing platform 44, the upper edge of the pushing part 47 stirs the reversible bearing platform 44 to rotate clockwise due to the limiting effect of the upper limiting block 45 and the return spring 29 on the slide block 28, so that the pedal 25 passes through the slide block 28 to be completely reset. After the pedal 25 passes the slide block 28, the reversible bearing platform 44 rotates along the counterclockwise direction to reset along with the gravity, so that the pushing part 47 can still press and press the upper edge of the reversible bearing platform 44 to transmit the pushing force from the pedal 25 to the slide block 28 when the pedal 25 is pressed again.

In this embodiment, a torsion spring is provided at the hinge 46 to ensure the position of the reversible platform 44 is restored. The torsion spring is deformed when the pushing part 47 pushes the reversible bearing platform 44 to rotate, and the reversible bearing platform 44 is driven to automatically turn over and reset through the elasticity generated by the deformation after the pushing part 47 passes over the reversible bearing platform 44.

Since the pedal 25 in this embodiment opens the paper cutting procedure that the knife seat 14 rapidly moves down after sliding into the second vertical section 4303, in order to avoid that the doctor cannot pull out the engagement paper 4 with a proper length by stepping to the end in the pedal pressing process, that is, the cutter 17 cuts the engagement paper 4, the following technical solution is further adopted in this embodiment:

first, as shown in fig. 12, an arrow indicating a height position at which the lower end cutting edge of the cutting blade 17 is lifted when the step 25 slides to the combined position of the first vertical section 4301 and the arc-shaped section 4302 of the guide post 43 is provided as the indicator mark 48 at a position above the sheet discharge port 20 on the right side of the case 5. At the same time, the arrow is used to remind the doctor that the paper-taking groove 50 is sufficiently exposed without further pressing the pedal 25 after the cutting edge of the lower end of the cutter 17 reaches the position.

Secondly, the arc sections 4302 disposed in the first vertical section 4301 and the second vertical section 4303 produce an additional function, that is, in a state that a doctor takes a sheet as shown in fig. 12, even if a small downward pressure is generated due to unstable sole of the doctor, the pedal 25 rotates around the turntable 42 due to the guiding action of the arc section 4302, that is, a buffering action is generated by the guiding action of the arc section 4302, so as to prevent the pedal 25 from directly sliding into the second vertical section 4303 from the first vertical section 4301 to start a sheet cutting procedure, so that the doctor can buffer the pedal sufficiently, so that the present embodiment does not need too high operation precision, and reduces operation difficulty.

Example 4

The embodiment does not provide the description of the drawings, and since the embodiment is different from the embodiments 1 to 3 only in the arrangement of the cutting knife 17, the skilled person can deduce the following description by referring to the drawings and combining the following descriptions:

the cutter 17 in this embodiment is rotatably disposed on the sidewall of the box 5 at the paper outlet 20, the cutting edge of the cutter 17 is a side portion rather than an end portion, and a paper cutting torsion spring is disposed at a rotational connection portion of the cutter 17. The paper cutting torsion spring controls the cutter body of the cutter 17 to seal the disposal opening in a natural state. The broach rope 8 is connected to the blade body to drive the cutter 17 to rotate and deform the cut torsion spring through the broach rope 8 also by depressing the pedal. After the tension of the broach rope 8 disappears, the cutter 17 is driven by the paper cutting torsion spring to rotate and return rapidly so as to cut off the occluded paper 4 at the paper outlet 20.
