The first clamping plate 11 is provided with a first weight-reducing hole 111, and the first weight-reducing hole 111 is used to reduce the weight of the first clamping plate 11. There are two first weight-reducing holes 111, and the two first weight-reducing holes 111 penetrate along the length direction of the first clamping plate 11. Arranging the first weight-reducing holes 111 along the length direction can reduce the number of times the first weight-reducing holes 111 are processed. The top surface of the first clamping plate 11 is provided with a first guiding slope 112, and the first guiding slope 112 is inclined toward the direction of the second clamping member 2, that is, the end of the first guiding slope 112 close to the second clamping member 2 is lower than the end away from the second clamping member 2. The first guiding slope 112 is provided to facilitate guiding the book to fall into the gap between the first clamping member 1 and the second clamping member 2. The first connecting plate 12 is provided with a hanging column 7, and the first reset member 3 is connected to the hanging column 7.

[0029] like Figure 4 As shown, in another embodiment, the first connecting plate 12 is also used as the first limiting plate 6513, that is, the first connecting plate 12 and the first limiting plate 6513 are the same component, and the first slide groove 61 is formed by combining two limiting plates 65 arranged on the base 6.

[0030] like Figure 5As shown, the second clamping member 2 includes a second clamping plate 21 and a second connecting plate 22, the second clamping plate 21 is located on the top surface of the seat body, the second connecting plate 22 is located on the bottom surface of the seat body, and the second connecting plate 22 is fixed to the second clamping plate 21 by screws, that is, the screws are screwed into the second connecting plate 22 and then pass through the second slide groove 62 to be screwed to the second clamping plate 21, and the rolling member 24 is installed on the second connecting plate 22.

The second connecting plate 22 is provided with a second weight-reducing hole 211, which is used to reduce the weight of the second connecting plate 22. There are two second weight-reducing holes 211, which penetrate along the length direction of the second connecting plate 22. Arranging the second weight-reducing holes 211 along the length direction can reduce the number of times the second weight-reducing holes 211 are processed. The top surface of the second connecting plate 22 is provided with a second guiding slope 212, which is inclined toward the direction of the first clamping member 1, that is, the end of the second guiding slope 212 close to the first clamping member 1 is lower than the end away from the first clamping member 1. The second guiding slope 212 is provided to facilitate guiding the book to fall into the gap between the first clamping member 1 and the second clamping member 2.

[0031] Both sides of the second connecting plate 22 extend downward to form a mounting portion 221, on which a rolling member 24 is provided. A hanging column 7 is also provided on the mounting portion 221, and a gap is provided between the two mounting portions 221, which is used to accommodate the rolling member 24 and the hanging column 7, and the second reset member 4 is connected to the hanging column 7.

[0033] like Figure 2 and Figure 7As shown, the driving mechanism 5 includes a driving shaft 51, a range extender 52, a traction member 53 and a traction machine 54. The range extender 52 is fixed on the driving shaft 51. The first end of the traction member 53 is fixed on the range extender 52, and the second end of the traction member 53 is fixed to the first connecting plate 12 of the first clamping member 1 after passing the rolling member 24. The driving shaft 51 is rotatably arranged on the base 6, and the traction machine 54 is connected to the driving shaft 51, and the traction machine 54 is used to drive the driving shaft 51 to rotate. The traction machine 54 drives the driving shaft 51 to rotate, and the driving shaft 51 drives the range extender 52 to rotate, and the range extender 52 reels the traction member 53, and the traction member 53 simultaneously pulls the first connecting plate 12 and the second connecting plate 22 to move toward each other, and the first connecting plate 12 drives the first clamping plate to move, and the second connecting plate 22 drives the second clamping plate to move, so that the first clamping plate and the second clamping plate move toward each other, that is, the traction member 53 simultaneously pulls the first clamping member 1 and the second clamping member 2 to move toward each other. When the traction machine 54 stops transmitting torque to the drive shaft 51, the first reset member 3 and the second reset member 4 simultaneously drive the corresponding first clamping member 1 and the second clamping member 2 to reset, and the first clamping member 1 and the second clamping member 2 reset and drive the traction member 53 to reset, and the traction member 53 drives the drive shaft 51 to reset. The range extender 52 is provided, and the travel length of the connection point between the traction member 53 and the range extender 52 can be increased when the same angle is rotated; in other words, when the required travel distance of the traction member 53 remains unchanged, the rotation angle of the drive shaft 51 is reduced.

[0034] The traction member 53 is a chain, the range extender 52 and the rolling member 24 are both sprockets, one end of the chain is welded to the sprocket, and the other end of the chain is welded and fixed to the first connecting plate 12. Of course, in other embodiments, the traction member 53 can also be a synchronous belt, the range extender 52 and the rolling member 24 are synchronous wheels; the traction member 53 can also be a rope, the range extender 52 is a wheel, and the rolling member 24 is a roller or a roller. Providing the rolling member 24 can avoid sliding friction between the traction member 53 and the second clamping member 2, reduce the wear of the traction member 53, and extend the service life of the traction member 53.

[0035] In another embodiment, the range extender 52 may not be required, and the first end of the traction member 53 may be fixed on the driving shaft 51 . In this case, the traction member 53 is usually a rope.

[0036] In another embodiment, Figure 8 As shown, the rolling member 24 may be omitted, and the second end of the traction member 53 may be directly passed through the hole provided on the second connecting plate 22 and then connected and fixed to the first clamping member 1. In this case, the traction member 53 is usually a rope.

[0037] The traction machine 54 is a handle, which is manually driven to reduce costs. The first clamping member 1 and the second clamping member 2 can be pulled to clamp the book by turning the handle. After the handle is released, the corresponding parts are reset under the action of the first reset member 3 and the second reset member 4. Of course, the traction machine 54 can also be a motor, which is easy to operate. After the motor stops outputting torque, the corresponding parts are reset under the action of the first reset member 3 and the second reset member 4.

[0038] When it is necessary to clamp a book, the handle is turned, the handle drives the driving shaft 51 to rotate, the driving shaft 51 drives the range extender 52 to rotate, the range extender 52 reels the traction member 53, and the traction member 53 simultaneously pulls the first clamping member 1 and the second clamping member 2 to clamp the book. After clamping is completed, the handle is released, the first reset member 3 and the second reset member 4 drive the corresponding components to reset, and there is no need to use the traction machine 54 for reset, which is convenient to operate.

[0039] The above are only implementation methods of the present utility model, and are not intended to limit the patent scope of the present utility model. Any equivalent structure made using the contents of the specification and drawings of the present utility model, directly or indirectly used in other related technical fields, are also within the patent protection scope of the present utility model.
