[0025] Example: Figure 1-7As shown, the adjustable chain belt includes a belt body 1 made of elastic material, the belt body 1 has a plurality of chain holes 2 arranged at intervals and a plurality of receiving parts 3 extending downward from each chain hole 2, the receiving part 3 has a plurality of limiting parts 301 and a plurality of connecting parts 302, the plurality of limiting parts 301 extend downward from the chain hole 2 and are arranged at intervals in the circumferential direction of the chain hole 2, the plurality of connecting parts 302 are arranged between any two adjacent limiting parts 301 and together with the plurality of limiting parts 301 form a receiving cavity 303, each limiting part 301 has an adjusting part 304 extending from its outer wall toward the receiving cavity 303 and protruding from the cavity wall of the receiving cavity 303, the plurality of adjusting parts 304 enclose a content space 305, the connecting part 302 and two adjacent adjusting parts 304 enclose an adjusting space 306 connected to the content space 305, the adjusting space 306 is located outside the content space 305 and forms a receiving cavity 303 with the content space 305. The present embodiment provides an adjustable chain belt to solve the problem that the hole diameter of the receiving part for inserting screws in the existing screw chain belt is not adjustable, resulting in that the chain belt can only adapt to screws of one specification and has low adaptability. The main method is to configure the receiving part 3 into a plurality of limiting parts 301 arranged at circumferential intervals in the chain hole 2 and a plurality of connecting parts 302 connecting adjacent limiting parts 301. The limiting part 301 has an adjusting part 304 for allocating the accommodating cavity 303 into a content space 305 and an adjustment space 306. Since the belt body 1 is made of elastic material, the content space 305 can expand outward to the total space of the entire accommodating cavity 303 (the sum of the space of the content space 305 and the adjustment space 306), so that the inner diameter of the accommodating cavity 303 can be adjusted to adapt to screws of different models, and the adaptability is good.

[0026] In the embodiment of the utility model, the adjusting portion 304 forms a V-shaped groove 307 on the outer wall of the limiting portion 301 and forms a trapezoidal protrusion 308 on the wall of the accommodating cavity 303, and the V-shaped groove 307 and the outer wall of the limiting portion 301 are gradually transitioned. Since the adjusting portion 304 forms a V-shaped groove 307 on the outer wall of the limiting portion 301 and forms a trapezoidal protrusion 308 on the wall of the accommodating cavity 303, the adjusting portion 304 has good structural strength, which prevents the adjusting portion 304 from breaking when the content space 305 expands outward.

[0027] In the embodiment of the utility model, the side of the adjusting portion 304 facing away from the outer wall of the limiting portion 301 is an arc surface arranged concentrically with the chain hole 2. The above arrangement configures the side of the adjusting portion 304 facing away from the outer wall of the limiting portion 301 to be an arc surface arranged concentrically with the chain hole 2, so that the inner wall of the content space 305 matches the shape of the screw, which facilitates the insertion of the screw.

[0028] In the embodiment of the utility model, the connecting portion 302 is arc-shaped and is arranged concentrically with the chain hole 2. The above arrangement configures the connecting portion 302 to be arranged concentrically with the chain hole 2, so that the expanded accommodating space matches the shape of the screw, which facilitates the insertion of the screw.

[0029] In the embodiment of the utility model, the limiting parts 301 are evenly distributed in the circumferential direction of the chain hole 2, and there are 4 to 6 limiting parts 301. Preferably, there are 5 limiting parts 301. Since there are 4 to 6 limiting parts 301 and they are evenly distributed in the circumferential direction of the chain hole 2, the inner diameter of the accommodating cavity 303 is adjustable, and at the same time, the receiving part 3 has good structural strength and is not easy to break when the screw is inserted.

[0030] In the embodiment of the utility model, the limiting portion 301 has a base 309 and a tail 310, the base 309 extends downward from the chain hole 2 and is inclined toward the axis of the chain hole 2, the tail 310 extends vertically downward from the base 309, the tail 310 has an adjustment portion 304, the adjustment portion 304 extends from the upper end of the tail 310 to the lower end of the tail 310, and the connecting portion 302 is connected to the lower end of the adjacent tail 310. Among them, the space enclosed by a plurality of bases 309 is for the nut portion of the screw to be inserted, and the space enclosed by a plurality of tails 310 is for the threaded portion of the screw to be inserted. The above arrangement configures the limiting portion 301 into a base 309 and a tail 310, so that the shape of the accommodating cavity 303 matches the shape of the screw, which facilitates the insertion of the screw.

[0031] In the embodiment of the utility model, a plurality of limit parts 301 are arranged at intervals in the circumferential direction of the chain hole 2 to form a plurality of upper adjustment holes 311, and a plurality of lower adjustment holes 312 are formed on the belt body 1, which are respectively connected to the plurality of upper adjustment holes 311, and the lower adjustment holes 312 are circular holes that slowly transition to the upper adjustment holes 311. The above arrangement avoids stress concentration at the connection between the limit part 301 and the belt body 1, and avoids breakage when the inner diameter of the accommodating cavity 303 changes, by providing the lower adjustment holes 312 connected to the upper adjustment holes 311 on the belt body 1.

[0032] In the embodiment of the utility model, the belt body 1 has a connecting hole 313 and a connecting buckle 314, a plurality of chain holes 2 are arranged at intervals in the length direction of the belt body 1 and are located between the connecting hole 313 and the connecting buckle 314, the connecting buckle 314 is snap-fitted with the connecting hole 313, and the connecting buckle 314 has a cylindrical portion 315 that is plug-fitted with the connecting hole 313 and two stopper portions 316 that are arranged on the cylindrical portion 315 to limit the cylindrical portion 315 from moving away from the connecting hole 313.
