[0015] The present invention will be described in detail below in conjunction with specific embodiments.
[0016] The structure of the ratchet wheel small included angle positioning device with V-shaped positioning groove with adjustable force value provided by the present invention is as follows figure 1 As shown, it includes a ratchet wheel 1 installed on the main shaft 2 and two positioning components 3. The ratchet wheel 1 can rotate around the Y axis shown in the figure. There are several V-shaped positioning grooves alternately distributed on both sides of the circumference of the ratchet wheel 1. The positioning components 3 are respectively installed on the brackets 4 on both sides of the ratchet wheel 1, such as figure 2 As shown, a rotation stop pin 5 is installed on the bracket 4 to limit the rotation of the positioning pin 7 around the X axis. The positioning block 6 of the positioning assembly 3 is sequentially installed with a positioning pin 7, a spring 8 and a posi...
