Preferably, the first limiting groove is an arc groove with a major arc structure, the second limiting groove is an arc groove with a minor arc structure, and the two arc grooves form a cylindrical first clamping area 250 together, so that after a pipe body of a workpiece is inserted into the first clamping area 250, the workpiece is mainly supported by the clamping block main body 220, the auxiliary clamping part 230 is used for carrying out auxiliary limiting on the pipe body of the workpiece, when the first locking screw 240 rotates and enables the auxiliary clamping part 230 to approach the clamping block main body 220, the inner diameter of the first clamping area 250 is reduced, the auxiliary clamping part 230 compresses the pipe body of the workpiece to position the pipe body of the workpiece, when the first locking screw 240 rotates and enables the auxiliary clamping part 230 to leave the clamping block main body 220, the inner diameter of the first clamping area 250 is increased, and the constraint force of the auxiliary clamping part 230 on the pipe body of the workpiece is reduced until the constraint force on the pipe body of the workpiece is relieved, so that the pipe body of the workpiece is taken out of the first clamping area 250.
