[0008] The fixed base and the anti-displacement mechanism are provided with a sleeve on the outside, and the top of the sleeve is sealed with a cover plate and fastened with a third hex bolt, so that the sleeve is reliably fixed to the aluminum template and prevents displacement.
[0009] In practical applications, the bolt includes a first bolt and a second bolt, with the first bolt and the second bolt located on opposite sides of the first internal hex bolt.
[0010] The length of the through screw is greater than the height of the sleeve.
