The first transmission assembly comprises a first fixed seat 5, a first hook head 3, a first connecting rod 7, a first guide block 4 and a first connecting block 6, in the preferred technical scheme, referring to fig. 3-4, the first fixed seat 5 is of an L-shaped plate structure consisting of a transverse plate 51 and a vertical plate 52, an opening extending towards the vertical plate 52 is formed at the joint of the vertical plate 52 and the transverse plate 51, the opening is vertically formed downwards from the upper end face of the vertical plate 52, and the lower part of the opening is in smooth transition with the transverse plate 51. The transverse plate 51 of the first fixing seat 5 is provided with a long hole 53, and the long hole 53 extends along the length direction of the first fixing seat 5. The central axes of the opening 54, the elongated hole 53 and the first fixing seat 5 are coplanar. Two first guide blocks 4 are fixed on the surface of the transverse plate 51 of the first fixed seat 5 through bolts, the positions of the first guide blocks 4 correspond to the openings 54, and the first guide blocks 4 are in an arch bridge shape. The opening 54 and the first guide block 4 form a guide limit channel. The first fixing seat 5 is horizontally fixed, the end of the transverse plate 51 is fixed on the reinforcing rib 12 of the mounting bracket, and the end of the vertical plate 52 is fixed on the lower part of the cambered surface body 2. Specifically, the first hook 3 passes through the opening 54 and is inserted into the first guide block 4, so that the first hook 3 is slidably disposed in the guide limit channel, and the sliding direction of the first hook 3 is the same as the opening direction of the piston ring. The first hook head 3 is in clearance fit with the opening 54 and the first guide block 4 to limit the first hook head 3 to shake, and the stability of the assembling process is improved. The hook part of the first hook head 3 extends into the opening of the piston ring through the abdicating notch.
