Example 2

[0044] like Figure 1 and Figure 2 As shown, on the basis of Example 1, in order to reduce the wear of the edge of the opening 101 caused by the top deviation of the synchronous belt 2, more specifically, the slide groove 106 is arranged on both sides of the inside of the clamping mouth; the sliding member 301 is arranged on the slide groove 106, and a connecting rod three is arranged to connect the two sliding members 301, and the connecting rod three passes through the through hole 304, so that the clamping block 3 can move along the slide groove 106; the top pressure plate 306 is fixedly arranged at the bottom of the clamping block 3 by a plurality of screws; the screw is an adjusting screw, and the adjusting screw is used to adjust the gap 704 between the top pressure plate 306 and the clamping block 3, and the fixed position of the synchronous belt 2 is corrected by adjusting the space between the clamping block 3 and the top of the accommodating cavity 502, so as to reduce the wear of the edge of the opening 101 caused by the top deviation of the synchronous belt 2.

[0045] like Figure 5 As shown, in order to make the guiding of the clamping block 3 more accurate and further reduce the wear of the edge of the opening 101, an operating groove is provided at the bottom of the top pressure plate 306, so that the operating groove is located above the clamping port. Fixed plates 9 are provided on both sides of the clamping port, and a fixed groove 901 is provided on the top of the fixed plate 9. A corresponding protrusion is provided in the movable cavity 2 102, and the protrusion is used to extend into the fixed groove 901, thereby limiting the left and right position of the fixed plate 9, and the clamping member 4 is located between the two fixed plates 9.

[0046] Specifically, a connecting hole 903 is provided at the bottom of the fixing plate 9, and a corresponding connecting hole 2 is provided at the bottom of the clamping member 4. A connecting rod 8 is provided to extend into the connecting hole 903 and the connecting hole 2, so that the clamping member 4 can be driven to rotate with the connecting rod 8 as the base point, thereby driving the support frame 701 to resist the synchronous belt 2.

[0047] Specifically, a mounting groove is provided at the bottom of the pressing member 4 , a guide block 2 5 is movably provided on the mounting groove, limiting parts are provided on both sides of the guide block 2 5 , the limiting parts are inclined, and the connecting rod 1 8 passes through the guide block 2 5 .

[0049] Specific use process: the support frame 701 is in a compressed state. Fig. 9 As shown, the guide block 703 drives the clamping member 4 to rotate around the connecting rod 8, driving the inclined surface 402 to contact the support rod 705; driving the clamping member 4 to continue to rotate, thereby pushing the support frame 701 to rotate counterclockwise, so that the protrusion 702 moves along the inclined surface 3 of the support block 3061 until the limiting rod contacts the strip groove 902, ensuring that the support frame 701 presses the clamping block 3 to a predetermined position, so that the limiting tooth 302 is engaged with the synchronous belt 2, and the support frame 701 is in a clamped state; as shown in FIG. Figure 5 As shown, after the guide block 1 703 is loosened, the clamping member 4 rotates to another limit rod against another strip groove 902 due to the center of gravity offset and gravity, so that the second inclined surface 403 is away from a support rod 705, leaving room for the clockwise movement of the support frame 701.

[0050] The support frame 701 is in a loosened state. Figure 8 As shown, by driving the toggle part 604 to rotate around the connecting rod 2 603 as the center, the rolling body 602 arranged on the linkage part 601 is driven to contact the guide block 1 703; the toggle part 604 is driven to continue to rotate, so that the rolling body 602 can move along the inclined surface 4 7031 arranged on the guide block 1 703, thereby pushing the support frame 701 to rotate clockwise, so that the protrusion 702 is away from the support block 3061, and part of the connecting part 1 706 extends into the groove arranged at the bottom of the top pressure plate 306, until the inclined surface 2 403 contacts a support rod 705, so that the clamping block 3 can slide downward along the slide groove 106 to a predetermined distance, leaving room for adjustment of the synchronous belt 2, and at this time the support frame 701 is in a loosened state. Example 3

[0051] like Figure 2As shown, on the basis of Example 2, in order to prevent the local impact force caused by the rigid connection of the above-mentioned structure from causing the component to break and the clamping block 3 to loosen, resulting in the loosening of the synchronous belt 2, a pin shaft 305 is provided on the bending part, and a movable cavity 2 102 is provided on one side of the bending part. A joint ring 303 is provided in the movable cavity 102, and the pin shaft 305 passes through the joint ring 303. A connecting part three is provided on the joint ring 303, and an adjusting part 307 is provided on the connecting part three. The movable joint ring 303 allows the clamping block 3 to have an operating deviation, thereby preventing the bending part from having a component breakage that causes the loosening of the synchronous belt 2, and reducing the deviation of the synchronous belt 2 or the wear of the edge, thereby extending the service life of the synchronous belt 2.

[0052] By setting an accommodating cavity 502 to accommodate the end of the synchronous belt 2 and the clamping block 3, a rotating clamping piece 4 is set to press the clamping block 3 to replace the connection method of the machine screw, a bending piece is movably set at the end of the clamping block 3, and a slide groove 106 is set at the left end of the clamping mouth, and a sliding rod is set on the bending piece, so that the clamping block 3 can be driven to slide up and down along the slide groove 106, thereby replacing the existing method of inserting the accommodating cavity 502 to the left and right positions to adjust the tension of the clamping block 3 and the synchronous belt 2, by setting a connecting rod three in the clamping mouth, and movably setting the clamping block 3 on the connecting rod three, while the clamping block 3 presses the synchronous belt 2, it can be rotated with the movable connection between the bending piece and the clamping block 3 as the base point, so that it is convenient for it to adjust its own posture during use and prevent the opening from being worn due to top deviation.
