DETAILED DESCRIPTION

[0025] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0026] like Figure 1-4 As shown, the crochet support mechanism 100 in one embodiment of the utility model includes a base arm assembly 10, a constraint block assembly 20 and a crochet arm 30. The base arm assembly 10 includes a base arm 111 extending in a first direction, and the constraint block assembly 20 is supported on the base arm 111 and can move along the extension direction of the base arm 111. The crochet arm 30 is used to fix the crochet 40, which is connected to the constraint block assembly 20 and can move in a second direction. In this embodiment, the first direction and the second direction intersect at a certain angle, so that the crochet 40 can move in a two-dimensional plane, which is more convenient to adjust during use, can be adapted to different frames, and has higher practicality. Preferably, the first direction and the second direction are perpendicular.

[0027] Specifically, the constraint block assembly 20 includes a constraint block 21 and a constraint block fixing plate 22 that are relatively arranged. A first limiting groove 211 extending along a first direction is opened on the constraint block 21. The constraint block fixing plate 22 covers the first limiting groove 211. The hook arm 30 can move along its axial direction in the first limiting groove 211 and is blocked by the constraint block fixing plate 22 to prevent movement in other directions.

[0028] Furthermore, a second limiting groove 212 extending along the second direction is provided on the constraint block 21, and the base arm 111 is limited in the second limiting groove 212, so that the constraint block assembly 20 as a whole can move on the base arm 111. The extension direction of the second limiting groove 212 is the second direction, so the extension directions of the second limiting groove 212 and the first limiting groove 211 are perpendicular or intersecting at other angles.

[0029] Preferably, the second limiting groove 212 is located above the first limiting groove 211, and the hook arm 30 is located below the base arm 111, so the influence of the base arm 111 can be avoided as much as possible when operating the hook 40.

[0030] In this embodiment, the first limiting groove 211 and the second limiting groove 212 are connected to each other, so after installation, the base arm 111 is limited between the second limiting groove 212 and the constraint block fixing plate 22, and the hook arm 30 is limited in the first limiting groove 211 and the bottom of the base arm 111. Correspondingly, the thickness of the base arm 111 can be set to be the same as the depth of the second limiting groove 212, and the distance from the bottom of the first limiting groove 211 to the bottom of the second limiting groove 212 is the same as the thickness of the hook arm 30. After such a setting, the hook arm 30 will not lift up the base arm 111, and the base arm 111 will not lift up the constraint block fixing plate 22 at the same time, and the overall stability is higher.

[0031] It is easy to imagine that the widths of the first limiting groove 211 and the second limiting groove 212 are respectively set to be the same as the widths of the crochet arm 30 and the base arm 111, so there is no excess gap between the constraint block assembly 20 and the base arm 111 and the crochet arm 30, and the constraint block assembly 20 and the crochet arm 30 will not shake or displace in other directions when moving, and have higher stability.

[0032] In this embodiment, the restraint block 21 and the restraint block fixing plate 22 are detachable, which is convenient for overall disassembly and maintenance. The restraint block 21 and the restraint block fixing plate 22 are fixed by bolts, which can also be snap-fit ​​or other fixing forms, which are not limited in this embodiment.

[0033] In order to prevent the hook arm 30 from moving too much and causing it to be out of the first limiting groove 211, a first stopper 31 is provided at the end of the hook arm 30 at a position for fixing the hook. The first stopper 31 can be provided along any direction perpendicular to the extension direction of the first limiting groove 211, and only needs to be blocked by the restraining block 21 and / or the restraining block fixing plate 22 and / or the base arm 111 when the hook arm 30 moves. Figure 1 In the embodiment, the first stopper 31 protrudes upward and is blocked by the base arm 111 and / or the restraining block fixing plate 22 .

[0034] In one embodiment, the base arm assembly 10 further includes a base arm body 11 and a base arm fixing plate 12, and the base arm 111 extends from the base arm body 11 along a first direction. The base arm body 11 and the base arm fixing plate 12 are detachably fixed to each other, and a fixing groove 13 is formed between the two, and the base arm body 11 is fixed to the device frame through the fixing groove 13. Preferably, the base arm body 11 and the base arm fixing plate 12 are fixed by bolts, and of course, other fixing forms such as buckles can also be used, which is not limited in this embodiment.

[0035] like Figure 1 and 2 As shown, the cross-sectional shape of the fixing groove 13 is circular, and the corresponding fixed end of the device is cylindrical, so the orientation of the base arm 111 can be adjusted by loosening the fixing bolts on the base arm body 11 and / or the base arm fixing plate 12, which is more flexible.

[0036] Preferably, a second stopper 112 protrudes from the end of the base arm 111 to block the constraint block assembly 20 and prevent it from excessively moving and disengaging from the base arm 111, so as to improve stability. The second stopper 112 can protrude downward (e.g. Figure 2 As shown), it may also protrude upward or to both sides, which is not limited in this embodiment.

[0037] In actual operation, after determining the position, the base arm body 11 and the base arm fixing block 12 are fixed with screws, and then the hook needle arm 30 is placed in the first limiting groove 211, and the base arm 111 is limited in the second limiting groove 212, and the constraint block 21 and the constraint block fixing plate 22 are pre-tightened with screws, and the position of the hook needle is fine-tuned in two directions perpendicular to each other (for example, the first direction represents the X-axis direction, and the second direction represents the Y-axis direction) by moving the constraint block assembly 20 and the hook needle arm 30, and the fixing screws between the constraint block fixing plate 22 and the constraint block 21 are completely tightened after the adjustment is completed. When the offset of the hook needle needs to be adjusted, loosen the fixing screws between the constraint block 21 and the constraint block fixing plate 22, and tighten the fixing screws after the adjustment is completed.

[0038] In this embodiment, the first limiting groove 211 and the second limiting groove 212 on the constraint block 21 limit the moving direction of the constraint block 21 itself and the crochet arm 30 (vertically or intersecting at other angles); at the same time, the two limiting grooves are connected to each other, and after fixing the constraint block 21 and the constraint block fixing plate 22, the crochet arm 30 and the base arm 111 are squeezed against each other, and a large friction force is formed between the two. The friction force is used to fix the constraint block 21 and the crochet arm 30 in a predetermined working position and limit the freedom of movement of the two, and the stability is higher.

[0039] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
