The first clamping plate 32 and the second clamping plate 33 are clamped in the up-down direction by the locking action of the clamping element 34, the first clamping plate 32 and the second clamping plate 33 do not completely clamp the sub fixing seat 31 because the thickness of the supporting piece 35 is larger than that of the sub fixing seat 31, and the sub fixing seat 31 and the supporting piece 35 have a gap in the left-right direction, so that the sub fixing seat 31 can move in the left-right direction, thereby allowing the guide rod 1 to move in the left-right direction.

Because the thickness of the supporting member 35 is only slightly greater than that of the auxiliary fixing seat 31, the first clamping plate 32 and the second clamping plate 33 also apply an acting force to the auxiliary fixing seat 31, and although the acting force cannot hinder the small-amplitude movement of the guide rod 1 caused by the expansion and contraction of the slider 300, the large-amplitude movement of the guide rod 1 caused by the vibration of the stamping process can be prevented, that is, the large-amplitude shaking of the whole guide rod 1 can be avoided.
More specifically, the clamping member 34 is a screw, the first clamping plate 32 has a threaded hole 320, the second clamping plate 33 has a through hole 330, the screw passes through the through hole 330 and engages with the threaded hole 320, and a screw head of the screw contacts with the second clamping plate 33.

It is worth mentioning that in the present embodiment, the first clamping plate 32 is disposed on the upper side of the second clamping plate 33, while in other embodiments, the first clamping plate 32 is also disposed on the lower side of the second clamping plate 33.
More specifically, the secondary fixing base 31 has a channel 310, the supporting member 35 is a sleeve, the sleeve is located in the channel 310, the sleeve and the channel 310 have a gap in the left-right direction, and the screw passes through the sleeve. The above structure is equivalent to that the clamping element 34 and the supporting piece 35 are both arranged in the projection range of the auxiliary fixing seat 31 along the vertical direction, so that the occupied space of the auxiliary limiting device 3 in the horizontal direction can be effectively reduced.
More specifically, the sleeve is cylindrical in shape, the passage 310 is a cylindrical passage, and the sleeve has a gap in the horizontal direction from the passage 310. The cylindrical design facilitates the manufacture of the sleeve and the auxiliary fixing seat 31; since the main limiting device 2 limits the guide rod 1 in the up-down and front-back directions, even if the channel 310 does not limit the sleeve (or the sleeve does not limit the secondary fixing seat 31), the guide rod 1 cannot rotate around the positioning pin 22 passing through the inner hole 11.
More specifically, the screw and the sleeve are plural, and the plural sleeves are arranged around the guide bar 1. Such a structure can make the clamping forces of the first clamping plate 32 and the second clamping plate 33 more uniform.
The above-described embodiments are merely preferred examples of the present invention, and not intended to limit the scope of the utility model, so that equivalent changes or modifications in the structure, features and principles of the utility model described in the claims should be included in the claims.
