[0024] The support assembly 1 includes a long sleeve rod 11 and a threaded groove 12 opened in the middle of the upper end of the long sleeve rod 11 . The threaded rod 412 is threadedly connected to the inner cavity of the threaded groove 12 opened in the middle of the upper end of the long sleeve rod 11 .
[0025] The mounting mechanism 41 includes a gripping rod 411 and a threaded rod 412 fixedly mounted on the lower end of the gripping rod 411 . A hollow ring 413 is fixedly mounted on the upper end of the gripping rod 411 .
[0026] The rotating mechanism 42 includes a semi-threaded rod 421 and slots 422 linearly and evenly spaced on the upper end of the outer wall of the semi-threaded rod 421 . The semi-threaded rod 421 is movably installed in the inner cavity of the hollow ring 413 .
[0027] One end of the semi-threaded long rod 421 is threadedly connected to a fixing nut 423, and short columns 424 are fixedly installed at the four corners of one end of the fixing nut 423. A circular ring 425 is fixedly installed at one end of the short column 424. The circular ring 425 is arranged to drive the fixing nut 423 to be threadedly connected to the outer surface of the semi-threaded long rod 421.
[0028] In this embodiment: when the operator uses the bearing clamp, the threaded rod 412 can be directly threaded into the inner cavity of the threaded groove 12 according to the usage distance of the bearing clamp, and the overall usage length of the long sleeve rod 11 can be extended by adjusting the threaded connection position of the threaded rod 412 in the inner cavity of the threaded groove 12. At the same time, the operator can insert the semi-threaded long rod 421 into the inner cavity of the hollow ring 413, and drive the short column 424 and the fixing nut 423 to move by rotating the ring 425, so that the fixing nut 423 is threadedly connected to the semi-threaded long rod 421, and the semi-threaded long rod 421 is fixedly installed on the hollow ring 413 by threading the fixing nut 423 on both sides of one end of the semi-threaded long rod 421. This arrangement makes it easy for the operator to drive the holding rod 411 and the long sleeve rod 11 to rotate by rotating the semi-threaded long rod 421, which is convenient to use.
[0029] Example 2: This example is an improvement made on the basis of Example 1. For details, please refer to Figure 4 The extension mechanism 43 includes a T-shaped insertion rod 431 and a circular groove 432 opened on one side of the upper end of the T-shaped insertion rod 431. An elastic element 433 is fixedly installed in the inner cavity of the circular groove 432, and a semicircular card ball 434 is fixedly installed on the upper end of the elastic element 433.
[0030] The T-shaped insertion rod 431 is movably installed in the inner cavity of the semi-threaded long rod 421 , and the semicircular locking ball 434 is movably locked in the inner cavity of the locking groove 422 under the elastic force of the elastic element 433 .
[0031] In this embodiment: when the operator is using the semi-threaded long rod 421, if the operator needs to extend the usable length of the semi-threaded long rod 421, he can directly press the semicircular card ball 434 embedded in the inner cavity of the card slot 422, so that the semicircular card ball 434 retracts under the elastic force of the elastic element 433, and move the T-shaped insertion rod 431 as needed. In the process of pulling the T-shaped insertion rod 431, the T-shaped insertion rod 431 drives the elastic element 433 and the semicircular card ball 434 to be re-engaged in the inner cavity of the card slot 422 opened at the upper end of the semi-threaded long rod 421 for re-fixation. This arrangement makes it easy for the operator to retract the T-shaped insertion rod 431 when not in use.
[0032] Working principle: When using the bearing pick, the operator can directly install the threaded rod 412 into the inner cavity of the thread groove 12 according to the use distance of the bearing pick, and extend the overall use length of the long sleeve rod 11 by adjusting the threaded connection position of the threaded rod 412 in the inner cavity of the thread groove 12. At the same time, the operator can insert the semi-threaded long rod 421 into the inner cavity of the hollow ring 413, and drive the short column 424 and the fixing nut 423 to move by rotating the ring 425, so that the fixing nut 423 is threadedly connected to the semi-threaded long rod 421. By threading the fixing nut 423 on both sides of one end of the semi-threaded long rod 421, the semi-threaded long rod 421 is fixedly installed on the hollow ring 413. The setting can facilitate the operator to drive the holding rod 411 and the long sleeve rod 11 to rotate by rotating the semi-threaded long rod 421. If it is necessary to extend the usable length of the semi-threaded long rod 421, the semi-circular card ball 434 embedded in the inner cavity of the card slot 422 can be directly pressed by the movable card, so that the semi-circular card ball 434 retracts under the elastic force of the elastic element 433, and the T-shaped insertion rod 431 is moved as needed. In the process of pulling the T-shaped insertion rod 431, the T-shaped insertion rod 431 drives the elastic element 433 and the semi-circular card ball 434 to be re-engaged in the inner cavity of the card slot 422 opened at the upper end of the semi-threaded long rod 421 for re-fixation. This setting can facilitate the operator to retract the T-shaped insertion rod 431 when not in use.
