[0033] The output connecting shaft 20 is provided with a fixing rod 21, the connecting sleeve 30 is adapted to the fixing rod 21, the connecting sleeve 30 is sleeved on the outer wall of the fixing rod 21, and two groups of positioning grooves 22 are symmetrically opened in the fixing rod 21, a positioning assembly 40 is provided in the positioning groove 22, the positioning assembly 40 is connected to the connecting sleeve 30, and the positioning assembly 40 contacts the groove bottom of the positioning groove 22, so that the connecting sleeve 30 is positioned on the outer wall of the fixing rod 21.

[0034] In this embodiment, when the output connecting shaft 20 needs to be extended for connection, the contact between the positioning assembly 40 and the positioning groove 22 is released, so that the connecting sleeve 30 can slide on the fixing rod 21. When the connecting sleeve 30 is adjusted to a specified position, the positioning assembly 40 contacts the bottom of the positioning groove 22, so that the positioning assembly 40 cannot be displaced, thereby positioning the connecting sleeve 30 on the outer wall of the fixing rod 21.

[0035] By setting the sliding fit between the connecting sleeve 30 and the fixing rod 21 as mentioned above, it is possible to perform fine-tuning according to actual conditions, thereby increasing the diversity of the connection of the output connecting shaft 20 and improving the overall practicality. At the same time, through the cooperation between the positioning component 40 and the positioning groove 22, when the connecting sleeve 30 is adjusted to a suitable position, the connecting sleeve 30 can be effectively positioned, thereby facilitating improving the stability of the connection.

[0036] Specifically, the fixing rod 21 is a regular hexagonal prism, and a fixing slot hole matching the fixing rod 21 is provided in the connecting sleeve 30, and the fixing rod 21 is tightly fitted with the fixing slot hole;

[0037] The rotation of the fixing rod 21 drives the connecting sleeve 30 to rotate.

[0038] In this embodiment, during use, the connecting sleeve 30 is sleeved on the outer wall of the fixing rod 21, that is, the fixing rod 21 is set in the fixing slot, and then when the fixing rod 21 rotates, the connecting sleeve 30 is driven to rotate.

[0039] Specifically, the outer wall of the connecting sleeve 30 is provided with a plurality of groups of spline grooves 32 , and the plurality of groups of spline grooves 32 are arranged in a ring array in the axial direction of the connecting sleeve 30 .

[0040] Specifically, a rack A23 is provided in the positioning groove 22;

[0041] The positioning assembly 40 includes a rack B41 , the rack A23 is matched with the rack B41 , a positioning screw 43 is rotatably provided on the rack B41 , and the positioning screw 43 is connected to the connecting sleeve 30 .

[0042] Specifically, the connection sleeve 30 is provided with a positioning threaded hole 31, and the positioning screw 43 is threadedly connected in the positioning threaded hole 31;

[0043] The positioning screw 43 rotates in the positioning threaded hole 31 , so that the rack B41 contacts the rack A23 , thereby positioning the connecting sleeve 30 .

[0044] In this embodiment, when the connecting sleeve 30 is positioned, the positioning screw 43 rotates in the positioning threaded hole 31, so that the rack B41 moves toward the rack A23 until the rack B41 contacts the rack A23, thereby positioning the positioning screw 43 and thus positioning the connecting sleeve 30.

[0045] Specifically, the positioning screw 43 is provided with a hexagonal hole 42 .

[0046] In this embodiment, the hexagonal hole 42 is used to drive the positioning screw 43 to rotate.

[0050] Specifically, the fixing rod 21 is provided with a reinforcing threaded hole A24, and the connecting sleeve 30 is provided with a reinforcing threaded hole B34;

[0051] The reinforcement bolt 50 is disposed between the reinforcement threaded hole A24 and the reinforcement threaded hole B34.

[0052] Specifically, the length of the reinforcement threaded hole A24 is greater than the length of the positioning groove 22;

[0053] The length of the reinforcement bolt 50 is equal to the sum of the lengths of the reinforcement threaded hole A24 and the reinforcement threaded hole B34.

[0054] In this embodiment, when the distance between the connecting sleeve 30 and the output connecting shaft 20 is not adjusted, the reinforcing bolt 50 is connected between the reinforcing threaded hole A24 and the reinforcing threaded hole B34;

[0055] When the distance between the connecting sleeve 30 and the output connecting shaft 20 is adjusted to the maximum, since the length of the reinforcing bolt 50 is equal to the sum of the lengths of the reinforcing threaded hole A24 and the reinforcing threaded hole B34, and the length of the reinforcing threaded hole A24 is greater than the length of the positioning groove 22, the reinforcing bolt 50 is always connected between the reinforcing threaded hole A24 and the reinforcing threaded hole B34 to ensure the stability of the connection between the connecting sleeve 30 and the fixing rod 21.
