400


to be pivotally connected with the two pivotal lugs


31


of the first connecting rod


3


, and the other end provided with two pivotal lugs


41


extending forward and respectively having an insert hole


410


. The second connecting rod


4


further has one side provided with a lengthwise elongate projection


42


to be engaged with the lengthwise recessed groove


33


of the first connecting rod


3


, and the other side bored with a lengthwise recessed groove


43


opposite to the lengthwise elongate projection


42


.




The locking rod


5


to be pivotally connected with the second connecting rod


4


by a connecting member


6


has one end provided with a pivotal lug


50


extending outward and having an insert hole


500


to be pivotally connected with the two pivotal lugs


41


of the second connecting lug


4


, and the other end provided with a protruding-out locking member
