Preferably, the width of the vertical groove is 5 mm.
Preferably, three sets of stud mounting grooves are arranged.
Preferably, two clamping nuts are respectively arranged at two ends of the stud bolt.
Preferably, an elastic gasket is arranged on the stud between the end part of the stud mounting groove and the adjacent clamping nut.
