[0015] By adopting the above technical scheme, the spring is sleeved on the limiting block, so that the spring elastic force is stable, and the spring is not easy to deform, the anti-disengagement block is slidably arranged in the anti-disengagement groove, when the spring drives the limiting block to be separated from the containing groove, the anti-disengagement block limits the sliding distance of the limiting block, and prevents the limiting block from being separated from the containing groove.

[0016] Optionally, the end of the limiting block close to the wall of the sliding groove is provided with a circular arc block, and the circular arc block is clamped in the containing groove.

[0017] By adopting the above technical scheme, the circular arc block makes the limiting block better separate from the limiting groove, and the adjustment is more convenient.

[0018] In summary, the present application has at least one of the following beneficial technical effects:

[0019] 1. When the hardboard needs to be sewn with a cover, the staff places the hardboard in the guide frame, moves the hardboard through the sewing machine to sew the cover on the hardboard, the cover sewing line is horizontal to the edge of the hardboard, and the sewing distance is consistent, and the certificate shell is beautiful;

[0020] 2. When the guide frame needs to be adjusted in size, the sliding block slides, the spring drives the limiting block to be clamped in the limiting groove, and the size adjustment of the guide frame is simple.

[0021] 3. When the spring drives the limiting block to be separated from the containing groove, the anti-separation block prevents the limiting block from being separated from the containing groove, and the spring sleeve is connected to the limiting block to stabilize the spring elasticity and not be easily deformed.
