The winding module 200 comprises a bottom plate 210, a fixed shell 240 is fixedly connected to the side surface of the bottom plate 210, a connecting seat is fixedly connected to one side of the top surface of the bottom plate 210, the connecting seat is rotatably connected with a pedal 220 in contact with the fixed shell 240 through a shaft rod, a sliding groove 241 is formed in one side of the side surface of the fixed shell 240, which is far away from the connecting seat, a round block 250 which is slidably connected with the top of the sliding groove 241 is slidably connected to the top of the side surface of the pedal 220, a winding reel 260 is rotatably connected to the inner side surface of the fixed shell 240, a hose 230 is fixedly connected to the top surface of the fixed shell 240, the top end of the hose 230 is fixedly connected with one end of a conduit 150, one end of a connecting wire I sequentially passes through the top of a side frame 140, the conduit 150, the hose 230 and the top of the fixed shell 240, one end of the connecting wire I is wound on the side wall of the winding reel 260, a winding rod 261 which is fixedly connected with the inner side surface of the round block 250 is fixedly connected with the inner side surface of the fixed shell 240, a wire blocking block 242 is fixedly connected to one side of the top of the sliding groove 241, the wire blocking block 242 is positioned between the wire winding rod 261 and the round block 250, the side surface of the round block 250 is fixedly connected with the second connecting wire, one end of the second connecting wire bypasses the top of the side wall of the wire blocking block 242 and is wound on the side wall of the wire winding rod 261, when the pedal 220 is pressed downwards, the round block 250 can drive the second connecting wire to slide downwards along the sliding groove 241, due to the blocking of the wire blocking block 242, when the round block 250 drives the second connecting wire to move downwards, one part of the second connecting wire can be released from the wire winding rod 261, so that the wire winding rod 261 can drive the wire winding disk 260 to rotate, the wire winding disk 260 winds the first connecting wire, the first connecting wire drives the adjusting block 121, the glass plate loosens the book, after the pedal 220 is loosened, the adjusting block 121 can move downwards under the action of the first return spring 141, the glass plate is pressed on the book, when the adjusting block 121 moves downwards, the top end of the first connecting wire can be pulled downwards, therefore, a part of the first connecting wire is released from the winding roll 260, the winding roll 260 and the winding rod 261 are rotated, the second connecting wire 261 winds the second connecting wire, the round block 250 can move upwards through the second connecting wire, the pedal 220 is reset, the pressing frame 120 can be controlled to move through the foot, the auxiliary tool can be operated by combining hands and feet, and the work efficiency is improved.

The side of the pedal 220 is provided with a limit groove 221 corresponding to the round block 250, the side of the round block 250 is fixedly connected with a clamping block 251 which is in sliding connection with the limit groove 221, the clamping block 251 can limit the moving direction of the round block 250, and when the pedal 220 rotates, the clamping block 251 can slide in the limit groove 221, so that the round block 250 can smoothly slide along the sliding groove 241.

The working principle is as follows: when the book holder is used, the pedal 220 is stepped to enable the pedal 220 to rotate downwards, when the pedal 220 rotates downwards, the clamping block 251 can drive the round block 250 to move downwards along the sliding groove 241, when the round block 250 moves downwards, the connecting wire II can be pulled to enable one part of the connecting wire II to be released from the winding rod 261, at this time, the connecting wire II can enable the winding rod 261 to rotate, the winding rod 261 can drive the winding roll 260 to roll up, so that the connecting wire I of the winding roll 260 can enable the top end of the connecting wire I to pull the adjusting block 121 to move upwards, the adjusting block 121 can drive the pressing frame 120 and the glass plate to move upwards, and at this time, a book can be opened and placed on the placing plate 130;

after the account book is placed, the pedal 220 can be released, at this time, under the action of the first return spring 141, the adjusting block 121 can drive the pressing frame 120 and the glass plate to move downwards, so that the glass plate is pressed on the account book, when the adjusting block 121 moves downwards, the top end of the first connecting wire can be pulled downwards, so that a part of the first connecting wire is released from the winding roll 260, at this time, the winding roll 260 and the winding rod 261 can rotate, the second connecting wire is wound, the second connecting wire can enable the round block 250 to move upwards, so that the pedal 220 is reset, when the pressing frame 120 moves downwards, the unfolding rod 170 can be pressed on the account book, when the pressing frame 120 continues to move downwards, the unfolding rod 170 can be opened towards the two sides of the pressing frame 120, because under the action of the second return spring 173, the second ratchet rod 175 can be tightly attached to the first ratchet rod 162, so that the unfolding rod 170 can only rotate in one direction, therefore, when the unfolding rod 170 is attached to the side edge of the account book upper pressing frame 120 to move, the unfolding rod 170 cannot rotate, so that the unfolding rod 170 can unfold the paper of the account book towards two sides, and then the glass plate can be pressed on the account book;

glass plate pressure is back on the account book, the mechanism of making a video recording can see through the glass plate and take a photograph the account book, the staff can look over the data on the account book of shooting through the display, then type and statistics, when needs turn over the page, can trample the footboard 220 again, with glass plate rebound, loosen the account book, then can turn over the account book and continue to type and account, when glass plate rebound, under torsion spring 190's effect, can make connecting rod 160 rotate to pressing frame 120 center, the pole 170 that stretches out simultaneously can roll on the account book and can not stir the paper of account book.
