It will be appreciated that the grip may be abutted against at least one of the first segment 1151 and the second segment 1152 depending on how deep the rod 200 is inserted into the inner sleeve 2. If the diameter of the rod 200 is relatively large, the clamping portion of the inner sleeve 2 may only abut the first segment 1151, if the diameter of the rod 200 is relatively small, the clamping portion of the inner sleeve 2 may only abut the second segment 1152, and if the rod 200 is divided into different diameter segments, abutment with both the first segment 1151 and the second segment 1152 may be achieved.
According to the rod locking handle 100 of embodiment 2 of the present invention, the matching cavity section 115 is sequentially divided into the second segment 1152 and the first segment 1151, which are coaxially arranged, from the cavity bottom to the insertion hole 123, so that the rod locking handle is suitable for inserting rod-shaped workpieces with different diameters, the diameters of rod-shaped products are different, and the steps inserted into the inner sleeve 2 are different, and therefore, the locking structure can lock rod-shaped products with multiple specifications (diameters).
Furthermore, the mating cavity segment 115 of the outer sleeve 11 in the bar lock handle 100 of embodiment 2 of the present invention is not limited to the provision of the first segment 1151 and the second segment 1152. According to the specification number of the locking rod bodies, the number of steps of the inner sleeve 2 is correspondingly increased.
Further, the cross section of the second segment 1152 and the cross section of the first segment 1151 may each be polygonal, and the included angle portion of the second segment 1152 and the included angle portion of the first segment 1151 are disposed in one-to-one correspondence, and the side portion of the second segment 1152 and the side portion of the first segment 1151 are disposed in one-to-one correspondence.
