At the same time, the spoke locking component 26 can efficiently and reliably lock the spokes 3, providing a stable guarantee for subsequent operations.

[0037] This utility model can measure spokes 3 at different angles, improving the applicability and flexibility of the device and meeting the needs of measuring spokes 3 at different angles.

[0038] The main body 1 of the device includes a mounting plate 11, a mounting block 13, and a clamping head 14. A curved groove 12 is provided on the upper left side of the mounting plate 11. The upper end of the mounting plate 11 is fixedly connected to the mounting block 13, and the upper end of the mounting block 13 is fixedly connected to the clamping head 14. A through groove 15, a horizontal groove 16, a limiting groove 17, and a receiving groove 18 are provided on the lower end of the mounting plate 11. The through groove 15 penetrates the mounting plate 11 and is connected to the horizontal groove 16, the limiting groove 17, and the receiving groove 18. The limiting groove 17 and the horizontal groove 16 are connected to the receiving groove 18. The receiving groove 18 is located in the middle of the lower end of the mounting plate 11. The horizontal groove 16 is located at the front end of the mounting plate 11 and penetrates into the receiving groove 18. There are two horizontal grooves 16 arranged symmetrically. The limiting groove 17 is located in the middle of the mounting plate 11 and at the front end of the receiving groove 18. There are two limiting grooves 17 arranged symmetrically.

[0039] The movable block 21 is installed at the front end of the mounting plate 11, the bolt 23 is located in the curved groove 12, and the nut 24 is in contact with the rear end of the mounting plate 11.

[0040] The movable block 21 is connected to the detachable component 25, and the fixed block 22 is connected to the spoke locking component 26.

[0041] The detachable component 25 includes a ring 252, a spring 253, a button 254, and a limiting component. The lower end of the moving block 21 has a circular groove 251. The inside of the circular groove 251 is fixedly connected to the ring 252. The front end of the ring 252 is fixedly connected to one end of the spring 253.

The two ends of the limiting rod 256 are respectively engaged with two limiting grooves 17.

[0043] If it is necessary to measure spokes 3 at different angles, rotate nut 24 so that nut 24 is away from mounting plate 11, so that bolt 23 can move in curved groove 12. Rotate moving block 21 to a suitable position, and then tighten nut 24 so that nut 24 fits against mounting plate 11 to achieve fixation, thereby meeting the needs of measuring spokes 3 at different angles.

[0044] If it is necessary to replace the moving block 21 with a different through hole 261 diameter, press down the button 254 so that the button 254 pushes the connecting rod 255. The connecting rod 255 drives the limiting rod 256 to disengage from the limiting groove 17. The limiting rod 256 loses the limitation of the limiting groove 17. At this time, rotate the limiting rod 256 so that the limiting rod 256 enters the transverse groove 16. Release the button 254. The button 254 resets under the action of the spring 253, thereby unlocking the limiting rod 256. The moving block 21 is unlocked accordingly. Then remove the nut 24 from the bolt 23, and then remove the moving block 21 for replacement.

[0045] When installing a new movable block 21, align the circular groove 251 of the movable block 21 with the through groove 15, place the bolt 23 in the curved groove 12, align the limiting rod 256 with the horizontal groove 16 and insert it into the horizontal groove 16, then press down on the button 254 so that the button 254 compresses the spring 253 and drives the limiting rod 256 from the horizontal groove 16 into the receiving groove 18. Then rotate the limiting rod 256 so that the limiting rod 256 enters the limiting groove 17. Release the button 254, and the button 254 will reset under the action of the spring 253, realizing the locking function of the movable block 21. At this time, use the nut 24 to fix the movable block 21.

[0046] The practical detachable component 25 makes the replacement of the movable block 21 simple, improves the maintainability and expandability of the device, and facilitates the replacement of movable blocks 21 of different specifications according to actual needs.

[0047] The spoke locking assembly 26 includes a fixing plate 263, a tightening block 265, and a threaded moving block 266.

The threaded moving block 266 has a connecting hole 267 in the middle and a sliding connection between the upper end of the threaded moving block 266 and the lower outer side of the tightening block 265.

[0048] The center points of the circular hole 264 and the connecting hole 267 are located on the same center line.

[0049] The tightening blocks 265 are provided at equal intervals and arranged on the same circle.

[0050] The plurality of tightening blocks 265 are trumpet-shaped.

[0051] One end of the spoke 3 is inserted into the clamping and fixing end 4 of the tensile testing machine and fixed. The other end of the spoke 3 is inserted into the connecting hole 267 of the threaded moving block 266 and then passes through the round hole 264 of the fixing plate 263. The threaded moving block 266 is rotated so that it moves upward. The inner end of the threaded moving block 266 contacts the outer end of the multiple tightening blocks 265 and pulls the multiple tightening blocks 265 inward, thereby tightly clamping the spoke 3. This achieves reliable locking of the spoke 3 and ensures that the spoke 3 will not loosen during measurement and other operations, thus improving the accuracy and stability of the measurement.

[0052] After the spokes 3 are locked, the fixing fixture of the tensile testing machine pulls the clamping head 14, the clamping head 14 pulls the mounting plate 11, the mounting plate 11 pulls the spoke fixing mechanism 2, and the spoke fixing mechanism 2 pulls the spokes 3 to realize the tensile test of the spokes 3.
