Further, the grip block 13 is provided with extension arm 131 to rotating motor 21 one side perpendicularly, be provided with the fourth travel switch that is used for detecting extension arm 131 on the fixing base 14, this fourth travel switch and controller communication connection, controller control rotates motor 21 and drives grip block 13 and resets to extension arm 131 and remove to touching fourth travel switch, before needs adjustment at every turn, can reset grip block 13 to an initial fixed position through fourth travel switch and set for the number of turns that rotate motor 21 needs according to the books thickness signal that first input module received again, rotate motor 21 is servo motor, can realize controlling the number of turns of corotation and reversal, set up the logical groove that supplies extension arm 131 to stretch out on the fixing base 14, extension arm 131 stretches out and contracts in logical groove and slides.

further, a first travel switch 222 and a second travel switch 223 are arranged on the sliding seat 22 in the sliding direction, the first travel switch 222 and the second travel switch 223 are in communication connection with the second driving device 215, and the first travel switch 222 and the second travel switch 223 are used for limiting the front and rear positions of the sliding stroke of the rotating motor 21, so that the sliding seat 22 is prevented from exceeding the stroke position, and the output shaft of the rotating motor 21 is prevented from being overloaded.

Further, a third travel switch 224 is arranged on the sliding seat 22 in the sliding direction, the third travel switch 224 is arranged at a position where the rotating motor 21 slides to a position where the driving rod 211 approaches the positioning seat 142, the third travel switch 224 is in communication connection with the controller, when the rotating motor 21 slides to the position of the third travel switch 224, the rotating speed of the rotating motor 21 is reduced, so that the driving rod 211 can be decelerated and positioned when needing to be positioned with the positioning seat 142, thereby reducing the interference, rotation and abrasion between the driving rod 211 and the positioning seat 142 in the process of positioning the rotating motor 21 to rotate and align, and facilitating the positioning of the driving rod 211 to the positioning hole 144 or the positioning groove 147;

preferably, a spring element 146 is disposed between the positioning rod 145 and the driving rod 211, the spring element 146 provides a restoring force when the driving rod 211 is pressed, and further, when the first driving device 221 drives the rotating motor 21 to slide towards the positioning seat 142, the spring element 146 has a buffering effect to protect the rotating motor 21 and prevent the rotating motor 21 from being overloaded.

Preferably, an auxiliary clamp plate is provided on the side of the clamping plate 13 close to the fixed plate 12, and the auxiliary clamp plate is in a sheet shape and extends upward from the clamping plate 13.

The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above-mentioned embodiments, and all technical solutions belonging to the idea of the present invention belong to the protection scope of the present invention. It should be noted that modifications and embellishments within the scope of the invention may occur to those skilled in the art without departing from the principle of the invention, and are considered to be within the scope of the invention.
