When it is actually used for assembly, please refer to the first to eleventh figures. Before the controller (1) corresponds to the assembly of the axle limit group (2), the outer ring gear (41) of the positioning assembly (4) is firstly assembled. ) Sleeve into the screw member (21), and let the projection (411) of the outer ring gear (41) fit into the groove (213) of the screw member (21); then, let the screw member (21) correspond to The controller (1) is assembled, that is, the shaft (11) is used to correspond to the shaft hole (211) of the screw member (21), and in order to accurately set the two, it is further outside the shaft (11) An engaging portion (112) is provided, the engaging portion (112) is a polygonal block, and an engaging groove (14) is provided at the shaft hole (211) corresponding to the engaging portion (112). 210) [Polygonal slot], so that it can be set with each other [as shown in the second figure]. Next, insert the elastic member (22) and the inner tube (23) in the first hollow container (212) of the screw member (21), and let the elastic member (22) be inserted into the inner tube (2). 3) After the second hollow container (233) is inside, the inner tube (23) is inserted into the first hollow container (212) of the screw member (21), and the outer surface of the inner tube (23) is axially provided. There is a track (234), and a convex guide bar (214) for linear movement of the inner tube (23) is provided in the first hollow container (212) corresponding to the track (234) [as shown in the third figure] (Shown); at the same time, let the trigger member (3) correspond to the shaft of the central through hole (232), the elastic member (22), and the screw member (21) passing through the inner tube (23). The hole (211), the fixing groove (210), and the hollow (111) in the controller (1) are positioned for positioning. The trigger (3) is used to compress the elastic member (22) and the inner tube ( 23) Limited in the first hollow container (212) of the screw member (21); further, the trigger member (3) may be an implementation state of a rope body, a rod body, etc., and its The above-mentioned compression and fixing method can be achieved through the knotting of the rope body or a buckle on the rope body, or a fastener [C-shaped buckle, etc.] on the pole body, etc., which is not limited to achieve in any way [such as the first Figures 4 and 7].

Continued, the positioning ring (42), the stopper (5) and the outer sleeve (6) are screwed into the outside of the screw member (21), and the outer end of the outer sleeve (6) is integrally formed with a cover (61) or A cover (61) is set corresponding to the group. In order to keep the set cover (61) in a stable position and not rotate, the cover (61) is provided with a plurality of notches (612) on the torus surface, and A hook (613) is provided on an end surface of the second tooth portion (611), and a convex portion (601) which engages with each other is provided at the outer tube (6) corresponding to the notch (612), Corresponding to the hook (613), a slot (602) for mutual latching positioning is provided, so that the cover (61) is stably assembled and positioned at the end of the outer casing (6); As shown in the figure, it can be seen in the figure that the engaging block (60) of the outer sleeve (6) can correspond to the second engaging block (53) of the engaging restricting member (5) and interlock with the restricting member (5).
