Furthermore, the position adjusting mechanism comprises a supporting plate 22 fixedly connected with the base 1, two limit screws 23 arranged left and right are fixed on the supporting plate 22, each limit screw 23 penetrates through the extending end of a corresponding lower template 21 and is in threaded connection with a locking nut 24, a spring 25 is clamped between the inner side of each lower template 21 and the supporting plate 22, the spring 25 is sleeved on the screw 23, the lower ends of the two lower templates 21 are inserted and sleeved on a plurality of guide rods 26 arranged in the left and right directions, and two ends of each guide rod 26 are fixed on the base 1.

Further, a hexagonal boss 331 is formed at one end of the adjustment sleeve 33.

Furthermore, a step hole 411 with an i-shaped cross section is formed in the middle of the stamping block 41;

the middle part of the adjusting sleeve 33 is fixed on the inner rings of two bearings 34 arranged left and right, and the outer ring of the bearing 34 is sleeved in the middle hole of the stepped hole 411;

the central axis of the bearing 34 is eccentric to the central axis of the stepped hole 411, and the central axis of the bearing 34 is lower than the central axis of the stepped hole 411.

Furthermore, a convex ring 332 is formed in the middle of the adjusting sleeve 33, inner end surfaces of inner rings of the two bearings 34 are respectively pressed against two end surfaces of the convex ring 332, an outer end surface of an outer ring of each bearing 34 is pressed against a corresponding pressure plate 35, and the pressure plate 35 is fixed in an outer end large hole of the stepped hole 411.

Furthermore, the lower corner of the right-angle plate 31 is formed with a round corner 311.

The working principle is as follows: firstly, the adjusting sleeve 33 is rotated, and the adjusting sleeve 33 can drive the two right-angle plates 31 to approach or move away from each other through the two screws 32, so that the distance between the two right-angle plates 31 is changed; the locking nuts 24 are unscrewed, the positions of the lower templates 21 can be adjusted, the distance between each lower template 21 and a corresponding right-angle plate 31 is equal, and then the locking nuts 24 are screwed down to position the lower templates 21, so that the distance between the two lower templates is changed;
