[0026] By adopting the above technical solution, the positioning block 25 plays a limiting role and can limit the rotation of the screw rod 26, which is convenient for controlling the limited movement of the two moving blocks 22 to achieve better use effect.

The cylindrical limit block 3 can be extended and telescopically moved in the sleeve 212 under the elastic force of the spring 1 213 inside the sleeve 212. The position of the matching identification groove 1 can make the unblocked cylindrical limit block 3 extend, so as to achieve better use effect. The positioning hole on the SMT splicing tape cooperates with the cylindrical limit block 3 to achieve preliminary positioning. Under the sliding connection between the slider 6 and the slide rail 5, the ruler 4 can be adjusted to contact with the SMT splicing tape.
