[0031] The connection assembly 200 includes two sets of sealing plates 201 arranged in the housing 101. The two sets of sealing plates 201 are respectively located outside the two sets of sealing plates 201. A locking screw 202 is arranged between the two sets of sealing plates 201. Through holes that fit the locking screw 202 are opened in the middle of the two sets of sealing plates 201. The locking screw 202 passes through the two sets of through holes. Both ends of the locking screw 202 have external threads and are threadedly connected with locking bolts 203. The two sets of locking bolts 203 are respectively pressed against the two sets of sealing plates 201, and the two sets of sealing plates 201 are respectively pressed against the two sets of primary sealing rings 105.
