[0026] Embodiment

[0027] As shown in Figure 1 and Figure 2 The utility model provides a kind of adjustable angle positioning shaft, including: positioning shaft stem 1, the both ends of positioning shaft stem 1 are respectively rotationally sleeved with positioning shaft sleeve 2, can make positioning shaft sleeve 2 stable rotation, the opposite end of positioning shaft sleeve 2 is respectively fixedly provided with positioning block 3, can be positioned to positioning shaft sleeve 2, avoid free movement;A set of limiting sleeve ring 4 is fixedly sleeved on the outer wall of positioning shaft stem 1, and limiting sleeve ring 4 is located between positioning shaft sleeve 2, limiting sleeve ring 4 is provided with fixed sleeve ring 5 between, fixed sleeve ring 5 is fixedly sleeved with positioning shaft stem 1, the outer wall of fixed sleeve ring 5 is provided with sliding slot 6, sliding slot 6 is movably sleeved with the positioning assembly 7 for being positioned to positioning shaft sleeve 2, can be guided to positioning assembly, make it stable movement.

[0028] As shown in Figure 2 and Figure 3As shown, the positioning assembly 7 comprises a sliding block 71 slidingly arranged inside the sliding groove 6, capable of guiding the sliding block 71 to move stably, one end of the sliding block 71 is fixedly connected with a fixed column 72, one end of the fixed column 72 is fixedly connected with a fixed block 73, the fixed block 73 can limit the position of the positioning plate 74 and the spring 75, the outer wall of the fixed column 72 movably sleeves the positioning plate 74, which can limit the positioning block 3 on the positioning shaft sleeve 2, the outer wall of the fixed column 72 sleeves the spring 75, one end of the spring 75 is fixedly connected with the fixed block 73, the other end of the spring 75 is fixedly connected with the positioning plate 74, which can provide pressure to the positioning plate 74 to avoid movement.

[0029] Further, the two ends of the positioning shaft rod 1 are respectively threadedly connected with a limiting bolt 8, which can limit the positioning shaft sleeve 2 to ensure stable rotation.

[0030] Secondly, the outer wall of the limiting sleeve ring 4 is provided with a clamping groove 9, and the two ends of the positioning plate 74 are respectively fixedly provided with a clamping block 10, which can limit the positioning plate 74 to make the limiting more stable.

[0031] Further, one side of the positioning plate 74 is fixedly provided with a group of limiting blocks 11 between the limiting sleeve ring 4 and the fixed sleeve ring 5, which can make the positioning plate 74 move more stably.

[0032] In addition, the sliding groove 6 and the sliding block 71 are arranged in a "convex" shape to prevent the sliding block 71 from disengaging from the sliding groove 6 and make it move more stably.

[0033] Finally, the positioning block 3 is arranged in an "L" shape to stably limit the rotation angle of the positioning shaft sleeve in cooperation with the positioning plate 74.

[0034] The working principle of the embodiment is that the spring 75 is in a natural stretched state, under the action of its elastic force, the positioning plate 74 is pushed towards the limiting sleeve ring 4, so that the clamping blocks 10 at both ends of the positioning plate 74 are tightly clamped in the corresponding clamping grooves 9 on the outer wall of the limiting sleeve ring 4. The movement of the positioning block 3 is limited, and the rotation of the positioning shaft sleeve 2 around the positioning shaft rod 1 is limited, so that the positioning shaft maintains a fixed angle, avoiding collision with the surrounding environment due to free rotation of the positioning shaft when the equipment is normally running but does not need to adjust the angle.

[0035] When the angle of the positioning shaft needs to be changed, the operator pulls the positioning plate 74 to move on the fixed column 72, at the same time, the positioning plate 74 moves to compress the spring 75 to store elastic potential energy, and the positioning plate 74 drives the clamping blocks 10 at both ends to move out of the inside of the clamping groove 9. When the positioning plate 74 moves around the outer wall of the fixed sleeve 5, the positioning plate 74 drives the sliding block 71 to move in the sliding groove 6 through the fixed column 72. When moving to a suitable position, the positioning plate 74 is loosened, the positioning plate 74 moves on the outer wall of the fixed column 72 through the elastic potential energy of the spring 75, the clamping blocks 10 at both ends of the positioning plate 74 are re-clamped into the clamping groove 9 corresponding to the position of the outer wall of the limiting sleeve 4, the clamping action again limits the rotation of the positioning shaft sleeve 2, stably fixes the positioning shaft at the adjusted angle, guarantees the stability of the positioning shaft in the subsequent working process, prevents the angle from being changed at will to collide with the surrounding environment, and meets the demand of the equipment for stable operation at a specific angle.

[0036] The above specific embodiments are only optional embodiments of the present application, and based on the technical scheme of the present application and the related inspiration of the above embodiments, the person skilled in the art can make various alternative improvements and combinations on the above specific embodiments.
