In another embodiment of the present invention, as shown in fig. 11, the two clamping portions 154 are protruded toward one side of the clamping gap 155 to form an elastic piece 156 for abutting against the guide block 141. Specifically, due to the elastic pieces 156, the guide block 141 can be clamped when the guide block 141 rotates into the clamping gap 155 only by the two elastic pieces 156 without arranging a wave ball screw, so that the guide block 141 can rotate along with the clamping piece 152.

Furthermore, the clamping portion 154 is further opened with a buffer through cavity 157 towards one side of the corresponding elastic sheet 156, and the buffer through cavity 157 is disposed corresponding to the elastic sheet 156, so that the elastic sheet 156 can move into the buffer through cavity 157 when being elastically deformed, and interference from the clamping portion 154 is avoided.

In another embodiment of the present invention, as shown in fig. 12 and 13, each assembling jig 14 includes a clamping seat 142 and a rotating seat 143, the rotating seat 143 is rotatably disposed in the corresponding assembling through hole 121, the lower end of the rotating seat 143 is connected to the corresponding guide block 141, the clamping seat 142 is mounted on the rotating seat 143, the clamping seat 142 is provided with a clamping hole 144 for clamping the part 50 to be marked, and the hole wall of the clamping hole 144 is embedded with a plurality of elastic abutting members 145. Specifically, by arranging the clamping seat 142 and the rotating seat 143, the clamping seat 142 can effectively clamp the part 50 to be marked through the clamping hole 144 of the clamping seat 142, and the elastic abutting parts 145 penetrate through and are embedded in the hole wall of the clamping hole 144, so that each elastic abutting part 145 can further realize accurate limiting on the part 50 to be marked arranged in the clamping hole 144, and the part is more stably arranged in the clamping hole 144.

In another embodiment of the present invention, as shown in fig. 1, 12 and 13, each assembling jig 14 includes a fastening sleeve 146, and the fastening sleeve 146 is sleeved on the corresponding clamping seat 142 and abuts against each elastic abutting piece 145. Specifically, by sleeving the fastening sleeve 146 outside the clamping seat 142, the fastening sleeve 146 can effectively limit each elastic abutting part 145, and the elastic abutting parts 145 are prevented from being separated from the clamping seat 142 under the extrusion and vibration effects of the part 50 to be marked.

The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
