The two ends of the connecting block are inserted in a connecting groove and a pin joint groove correspondingly. The connecting block is fixedly connected with the connecting groove. The two ends of the right fixed shaft are fixedly connected with a wall plate of the pin joint groove correspondingly, and the right fixed shaft and a right shaft hole are in rotation fit. The positioning block is inserted in a positioning block fixing cavity and fixed, the left end is matched with an arc groove in the connecting groove, and the right end is matched with a guiding position stop groove in the right fixed shaft.
