Preferably, said locating bush outer peripheral face is provided with second bulge loop, is convenient to operation, skids when preventing to push locating bush.
The handle place of the utility model winch is provided with the taper hole of locating bush and built-in positioning ball; Location pushing tow positioning ball embeds the knock hole on the gear wheel shaft outer wall during connection; Because locating bush inside is provided with stage clip, after it was pushed, locating bush can automatically return to original position.Positioning ball was in free state after locating bush broke away from original position, and handle is Assembly &Disassembly quickly and easily.
Description of drawings
Fig. 1 is the blast structural representation of the utility model winch;
Fig. 2 is the part sectional view of the utility model winch;
Fig. 3 is a winch A partial enlarged drawing shown in Figure 2.
The specific embodiment
As shown in Figure 1, a kind of hand winch comprises driving system; Supporting system and brake system; Supporting system mainly comprises supporting base, and driving system and brake system all are arranged on the supporting base, and brake system can adopt like Chinese patent 201020606524.2 described structures.
Legacy system comprises capstan winch 3, gear cluster 2, gear wheel shaft 4 and handle 1, and gear wheel shaft 4 two ends are connected with handle 1 with gear cluster 2 respectively, and the drum shaft in the middle of the capstan winch 3 is connected with gear cluster 2.Turning handle 1, capstan winch 3 rotate thereupon, thereby realize take-up.
Gear wheel shaft 4 connects handle one end and is fixed with hexagonal nut 5; Respectively be provided with a knock hole 501 on six sides of hexagonal nut 5; Handle 1 connection gear axle one end end face has the mounting groove 9 that cooperates with hexagonal nut 5; Mounting groove 9 sidewalls are provided with six and knock hole 501 cooresponding taper holes 901, are provided with positioning ball 902 in the taper hole 901.
The end that handle 1 is provided with mounting groove 9 is arranged with stage clip 7 and locating bush 6 from inside to outside, and locating bush 6 inwalls and handle 1 outer wall are provided with bulge loop 602 and ring-shaped step 904, and stage clip 7 is between bulge loop 602 and ring-shaped step 904, and integral body is positioned at locating bush 6.Handle 1 this end end is provided with annular slot 905, and annular slot 905 is embedded with clip 8, and clip 8 can stop locating bush 6 to break away from handle.One end outer peripheral face of handle 1 connection gear axle 4 also is provided with ring-shaped step 903, it be mainly used in carry out when pushing locating bush 6 spacing.Locating bush 6 outer peripheral faces are provided with bulge loop 601, skid when preventing to press down locating bush 6.
