[0066] The working principle of this utility model:

[0067] When in use, the paper to be bound is placed between the pressing blocks 201, and then the motor 501 is started through the controller. The output end of the motor 501 can drive the forward and reverse threaded rods 503 to rotate. The rotation of the forward and reverse threaded rods 503 causes the transmission block 502 to move to the opposite side along the outer surface of the forward and reverse threaded rods 503, and the transmission block 502 drives the pressing block 201 to move together. The pressing block 201 fixes the paper to be bound to the left and right. At the same time, the output end of the motor 501 can also drive the rear pulley 403 to rotate. The rear pulley 403 is connected to the front pulley 403 through a belt drive, so that the front pulley 403 also rotates The front pulley 403 can drive the support rod 402 to rotate, and the support rod 402 indirectly drives the connecting rod 401 to rotate. The connecting rod 401 can drive the gear 303 to rotate. The gear 303 rotates and engages with the tooth plate 301, so that the tooth plate 301 slides along the outer surface of the sliding rod 302 to the opposite side. The tooth plate 301 drives the sliding block 203 to slide along the inside of the sliding groove 202 to the opposite side. The sliding block 203 drives the pressing block 201 to move, so that the two telescopic plates 204 fix the paper to be bound front and back. Finally, the pressing assembly 2 and the paper are transported to the front end of the body 1 for binding.

[0068] To sum up: this clamping device for a binding machine, through the body 1, the clamping assembly 2, the transmission assembly 3, the rotating assembly 4, the drive assembly 5, the travel groove 6 and the locking assembly 7, solves the problem that every time the paper is placed into the body, the staff needs to manually arrange the paper and then put it into the body. This operation is cumbersome and greatly reduces work efficiency.
