The utility model has the advantages of short service life and difficulty in applying force, etc. As shown in the fourth and fifth figures, the present invention provides an elastic cushion body (215) which can avoid the joint hole of the joint member (30) and the ratchet head (2〇) (213). Directly rigid contact, wear creates clearance and affects the efficiency of use and service life. As shown in the second figure, the driving rod (1 〇) provided by the present invention is hollow and has a through hole (13) and a groove (126). ) and the flange (127) is integrally forged by the drive rod (10) to save material, reduce weight, reduce cost, and The overall structural strength of the driving rod (1 〇) is increased. As shown in the first and fourth figures, the body (21) of the ratchet head (2 〇) of the present invention is integrally extended with a narrow extension (211). The inner side surface (121) and the abutting surface (125) of the U-shaped seat (12) are offset by #, and the extended section (2u) can be narrowed and the specification is small because it is not limited by the size of the inner ratchet assembly. The width of the U-shaped seat (12) corresponding to the abutment is made smaller, and the small space of the present invention is operated. % % [Simple description of the drawing]
