In addition, one end of the driving block 244 is fixedly connected with the piston rod of the second driving cylinder 242; the other end of the driving block 244 is provided with two guide grooves; the structure of each guide groove is matched with that of each guide block 243, that is, the two guide grooves are inclined grooves, and the inclined directions of the inclined grooves are consistent with that of the guide blocks 243, so that the guide blocks 243 are slidably penetrated into the guide grooves in a one-to-one correspondence manner, and the two clamping blocks 241 are guided to approach or separate from each other.

Thus, when the two clamping blocks 241 are driven to approach each other, the second driving cylinder 242 can be started, the second driving cylinder 242 moves upwards to drive the driving block 244 to move upwards, and in the process that the driving block 244 moves upwards, the guide groove can be in sliding fit with the guide block 243 of the clamping block 241, and as the two guide blocks 243 are inclined from bottom to top gradually towards the direction away from each other, and the distance between the two guide grooves is fixed, in the process that the driving block 244 moves upwards, the guide groove can guide the two clamping blocks 241 to approach each other. Conversely, the second driving cylinder 242 moves downward to drive the driving block 244 to move downward, and the guiding groove can guide the two clamping blocks 241 to approach each other during the downward movement of the driving block 244.

Various other modifications and changes may be made by those skilled in the art based on the above-described technical solutions and concepts, and all such modifications and changes are intended to fall within the scope of the claims.
