[0025] Preferably, an adjustment block is provided at one end of the adjustment shaft 21 and the adjustment rod 31, and the adjustment block is configured to be cylindrical and coaxial with the corresponding adjustment shaft 21 or the adjustment rod 31, and anti-slip grooves are provided on the outer circumferential surface of the adjustment block to facilitate the operator to perform twisting adjustment.
[0026] like Figure 2 As shown, Figure 2 It is a view of the connection structure of the fixing frame; generally, the fixing frame 1 includes a base 11 and two support rods 12, the two support rods 12 are fixed in parallel to the base 11, the adjusting sleeve 22 and the rotating sleeve 33 are both arranged between the two support rods 12, the two sides of the adjusting sleeve 22 are respectively connected to the two support rods 12 through the first rotating shaft 6, and the two sides of the rotating sleeve 33 are respectively connected to the two support rods 12 through the second rotating shaft 7, thereby ensuring the stable rotation of the adjusting sleeve 22 and the rotating sleeve 33 around the corresponding first rotating shaft 6 or the second rotating shaft 7.
[0027] The utility model can freely adjust the hook body 5 fixed on the lateral adjustment part 2 in three directions by providing the lateral adjustment part 2, the angle adjustment part 3 and the rotation adjustment part 4, so that the pulling direction and the pulling position of the hook body 5 can be accurately adjusted to replace the manual pulling of medical staff, reduce the work intensity of medical staff, and facilitate accurate pulling. Embodiment 2
[0028] like Figure 3 As shown, Figure 3 It is a cross-sectional view of the connection structure of the lateral adjustment part and the rotation adjustment part; the interior of the adjustment sleeve 22 is provided with a connecting cavity 221, an avoidance cavity 222, a guide cavity 223 and a first placement cavity 224 in sequence along the axial direction, and correspondingly, a connecting section 211 and a guide section 212 are provided on the adjustment spindle 21, the connecting cavity 221 is threadedly connected to the connecting section 211, the cross-sectional diameter of the avoidance cavity 222 is larger than the cross-sectional diameter of the connecting section 211, so as to provide a passage space for the connecting section 211 during adjustment, the cross-sectional diameter of the guide cavity 223 is consistent with the cross-sectional diameter of the guide section 212, so as to stabilize the axial movement of the adjustment spindle 21 in the adjustment sleeve 22, the cross-sectional diameter of the first placement cavity 224 is larger than the cross-sectional diameter of the guide cavity 223, and is used to place the relevant components of the rotation adjustment part 4.
[0029] The rotation adjustment part 4 includes a fixed connection block 41, a locking sleeve 42 and a locking spring 43. The fixed connection block 41 is fixedly arranged at the end of the hook body 5. The locking sleeve 42 and the locking spring 43 are both sleeved on the guide section 212 of the adjusting spindle 21. The locking sleeve 42 can move along the axis of the adjusting spindle 21. One end of the locking sleeve 42 is clamped and fixed to the fixed connection block 41, and the other end is elastically connected to the adjusting sleeve 22 through the locking spring 43.
[0030] The axial movement of the locking sleeve 42 along the adjusting spindle 21 can realize the switching of the locked and unlocked states between the fixed connecting block 41 and the locking sleeve 42. The elastic repulsive force applied to the locking sleeve 42 by the locking spring 43 can ensure that the fixed connecting block 41 and the locking sleeve 42 are in a locked and clamped state, thereby fixing the rotation angle between the hook body 5 and the axis of the adjusting spindle 21.
[0031] Specifically, an adjustment cavity 421 is provided in the locking sleeve 42, and the cross-sectional diameter of the adjustment cavity 421 is consistent with the cross-sectional diameter of the guide section 212. A second placement cavity 422 is provided at the end of the adjustment cavity 421 near the adjusting sleeve 22. The two ends of the locking spring 43 are respectively arranged in the first placement cavity 224 and the second placement cavity 422. The locking spring 43 provides elastic repulsive force to the locking sleeve 42 and the adjusting sleeve 22 to make the locking sleeve 42 fit with the fixed connecting block 41.
[0032] The locking sleeve 42 is provided with a snap-in groove 423 at the end near the fixed connection block 41, and the fixed connection block 41 is provided with a snap-in block 411. The snap-in grooves 423 are evenly distributed in a ring around the axis of the locking sleeve 42. The snap-in blocks 411 and the snap-in grooves 423 are provided in a one-to-one correspondence. By inserting the snap-in blocks 411 in the one-to-one correspondence with the snap-in grooves 423, the snap-in fixing effect of the fixed connection block 41 and the locking sleeve 42 is achieved.
[0033] Generally, the cross-section of the snap-in block 411 is set to a right-angled trapezoid, the edge of the right-angled waist of the snap-in block 411 is fixedly set on the fixed connection block 41, and the edge corresponding to the long bottom of the snap-in block 411 is set outside the edge corresponding to the short bottom, so that during the insertion of the snap-in block 411 into the snap-in groove 423, under the influence of the inclined waist, the internal space enclosed by the snap-in block 411 decreases from large to small, thereby making it easier to insert the snap-in block 411 into the snap-in groove 423.
[0034] like Figure 4 As shown, Figure 4 It is a structural view of the end portion of the locking sleeve; preferably, at least 12 snap-in grooves 423 are provided, so that the hook body 5 can be adjusted to multiple angles such as vertical, ±30°, ±60°, etc. for traction.
[0035] The end of the locking sleeve 42 close to the adjusting sleeve 22 extends outward along the axial direction of the locking sleeve 42 to form a guide strip 424, and a guide groove 225 is provided on the outer circular surface of the adjusting sleeve 22 corresponding to the guide strip 424, thereby ensuring that the locking sleeve 42 only moves in the axial direction and avoiding relative rotation between the locking sleeve 42 and the adjusting sleeve 22.
[0036] like Figure 5 As shown, Figure 5 It is a cross-sectional view of the connection structure between the hook body and the adjusting spindle; it is worth noting that a rotation groove is provided in the hook body 5, and a rotation block 213 is provided at the end of the adjusting spindle 21, and the rotation block 213 is provided in the rotation groove, and the rotation block 213 is axially clamped and fixed in the rotation groove, and the rotation block 213 can only rotate axially in the rotation groove, so as to realize the rotation of the hook body 5 around the axis of the adjusting spindle 21. Similarly, the structure of the rotation connection between the connecting tube 32 and the end of the adjusting rod 31 is consistent with the connection structure between the hook body 5 and the adjusting spindle 21.
[0037] The above is only a preferred embodiment of the utility model, which is only illustrative and not restrictive. Those skilled in the art understand that many changes, modifications, and even equivalences can be made within the spirit and scope defined by the claims of the utility model, but they will all fall within the scope of protection of the utility model.
