Detailed Description

The following describes embodiments of the present invention with reference to the drawings.

Fig. 1 is a schematic view of a support stand according to an embodiment of the present invention. As shown in fig. 1, the supporting frame 4 is a hollow column. An annular structure 41 is arranged on the inner wall of the support frame 4. The inner wall of the first end of the support frame 4 is provided with a thread structure. The end of the second end of the support frame 4 is a tapered structure with gradually reduced diameter, and the end is open.

Fig. 2 is a schematic view of a tilting rod in an embodiment of the invention. Fig. 3 is an enlarged schematic view of a portion a in fig. 2. As shown in fig. 2 and 3, the first end of the tilting rod 3 is provided with a positioning surface 31. The diameter of the positioning surface 31 is larger than that of the main body of the tilting rod 3. The second end of the tilting rod 3 is provided with a crochet hook structure 32. Preferably, the second end of the seesaw rod 3 is an extending structure 33 with a diameter smaller than the main body of the seesaw rod 3. In this embodiment, the protrusion structure 33 is a semi-cylindrical structure. The crochet structure 32 is a radially projecting needle extending into the structure 33. The reach-in structure 33 facilitates the operation of the crochet hook structure 32 into a working environment of relatively small volume.

Fig. 4 is a schematic diagram of an embodiment of the present invention. Fig. 5 is a cross-sectional view of fig. 4. As shown in fig. 4 and 5, the tilting rod 3 is installed inside the supporting frame 4, the main body of the tilting rod 3 is sleeved inside the annular structure 41, and the crochet hook structure 32 extends out of the opening of the second end of the supporting frame 4. The warped rod 3 is externally sleeved with a spring 2, and the spring 2 is arranged between the positioning surface 31 and the annular structure 41. The positioning structure 1 is screwed into the supporting frame 4 through the thread structure of the inner wall of the first end of the supporting frame 4, and is fixed with the positioning surface 31. The length of the warped rod 3 extending out of the supporting frame 4, that is, the length of the crochet hook structure 32 extending out, can be adjusted by adjusting the depth of the positioning structure 1 screwed into the inner wall of the supporting frame 4. Specifically, in the present embodiment, the positioning structure 1 is an adjusting nut.

In a preferred technical scheme, a thread structure is arranged on the outer wall of the support frame 4 close to the second end. The position of the ring-shaped structure 41 is within the range of the thread structure of the outer wall of the support frame 4. At least one gap 42 along the axial direction of the support frame 4 is opened on the side wall of the support frame 4, and the gap 42 extends from the set position of the side wall of the support frame 4 to the second end of the support frame 4 and penetrates through the gap 42 on the bottom surface of the second end of the support frame 4. Wherein the set position is a position between the first end of the support frame 4 and the position of the ring structure 41. Preferably, the length of the starting end of the slot 42 from the second end of the support frame 4 is greater than the length of the thread structure of the outer wall of the support frame 4 from the second end of the support frame 4.

A fastening ring 5 that is movable in the axial direction of the support frame 4 is fixed to the side wall of the support frame 4. The fastening ring 5 is fixed on the outer side of the support frame 4 through a thread structure outside the side wall of the support frame 4. The width of the slot 42 decreases when the fastening ring 5 is moved towards the first end of the support 4 and the width of the slot 42 is restored when the fastening ring 5 is moved towards the second end of the support 4. Specifically, the fastening ring 5 includes a cylindrical section 51 and a truncated cone section 52. When the cylindrical section 51 moves along the axial direction of the supporting frame 4, due to the existence of the gap 42, and meanwhile, the supporting frame 4 is made of a material with certain elasticity, and in combination with the characteristic that the diameter of the circular truncated cone section 52 is gradually reduced, the circular truncated cone section 52 can tighten or loosen the supporting frame 4 along the radial direction, and when the supporting frame 4 is tightened along the radial direction, the annular structure 41 is tightened simultaneously to tightly wrap and fix the tilting rod 3, so that the tilting rod 3 can be kept stable in the working process.

Preferably, a handle 43 protruding in a radial direction of the support frame 4 is fixed to an outer side wall of the support frame 4. The operation is convenient.

The foregoing description is illustrative of the present invention and is not to be construed as limiting thereof, the scope of the invention being defined by the appended claims, which may be modified in any manner without departing from the basic structure thereof.
