the handle part is provided with a locking assembly, and the locking assembly is used for locking the clamping piece and the handle part to ensure that the clamping piece cannot rotate relative to the handle part.
Furthermore, the periphery of the upper end of the handle part is provided with an external thread, and the clamping piece is sleeved on the external thread in a thread fit manner.
Further, the locking assembly comprises a tooth groove formed in the lower end face of the clamping piece, a vertical guide groove is formed in the circumferential face of the handle portion, a clamping piece is sleeved on the handle portion below the clamping piece, a protruding block is arranged on the inner wall of the clamping piece, the protruding block is movably arranged in the vertical guide groove, teeth meshed with the tooth groove are arranged on the upper end face of the clamping piece, a fixing piece is arranged on the handle portion below the clamping piece, a spring is sleeved on the handle portion above the fixing piece, and one end of the spring is pressed below the clamping piece.
Further, the tooth grooves are one or a plurality of tooth grooves which are arranged at intervals on the circumference by taking the central line of the handle part as the axis.
To sum up, the utility model discloses for its beneficial effect of prior art is:
the utility model discloses simple structure, set up on the holder through square tail form cylinder, the holder is connected for dismantling with the stalk portion, realize because of long-term the use at square tail form cylinder, when wearing and tearing warp unable centre gripping, change it, avoid causing the waste of screw tap, rethread locking Assembly, make the locking between holder and the stalk portion, make the unable relative stalk portion of holder rotate, when screw tap and screw tap hinge bar erection joint use, its holder forms an organic whole with the stalk portion and is connected, can not lead to the fact idle running or break away from because of attacking the tooth rotation, influence the use.
