The fastener 50 is prevented from coming loose relative to the support member 10.

As shown in FIGS. 4 and 5, when the two fasteners 50 are in a relaxed state, the user can drive the adjustment portion of the spacing adjusting device 40 to cause axially opposite displacement of the first screw 41 and the second screw 42 relative to the adjusting portion. In order to adjust the axial length of the first screw 41 and the second screw 42 and the adjusting portion, thereby adjusting the distance between the two clamping members 30, so that the two clamping ends 32 can be adjusted to be close to or away from each other. Bearings 1 of different sizes are positioned such that the clip end 32 is positioned between the bearing 1 and the frame 2, and then the fastener 50 is tightened.

After the adjustment operation, the disassembly operation of the bearing 1 can be performed. The operation hole 13 of the support member 10 and the bearing 1 are bored by the screw 20, and the screw 20 screwed to the back of the bearing 1 by the nut 21 is suitable. Further, the bearing 1 can be detached or taken out from the frame 2 by driving the screw 20 to complete the operation of disassembling the bearing 1.

Therefore, the present invention can adjust the distance between the two clamping members 30 synchronously through the adjustment of the operation of the spacing adjusting device 40, which is quite convenient and fast in operation, and at the same time, the adjusting portion of the spacing adjusting device 40 and the first screw 41 and the second The screw 42 is screwed so that the displacement of the two clamping members 30 is more accurate.

6 and FIG. 7 are the second embodiment of the present invention, and the configurations of the other structures in FIG. 6 and FIG. 1 are similar to those of the first embodiment, and the same reference numerals are used to omit the description. The difference between FIG. 6 and FIG. 1 is that a fastener 60 is further disposed between the two clamping members 30 so that the clamping ends 32 clamp the workpiece and the two clamping members 30 are clamped. The clip end 32 is capable of applying a force against the workpiece.

In this embodiment, each of the extending portions 33 has an elongated slot 331. The fastener 60 includes a fastening screw 61 extending through the through slot 331 and being screwed to the fastening screw 61. The screw member 62 of the end portion of the slot 331 has a first tool end 611, and the screw member 62 has a second tool end 621. The first tool end 611 and the second tool end 621 are respectively located at the screw member 62. The outer position of the clamping member 30 is described and is driven by the user using a tool socket. Since the distance between the bearing 1 and the frame 2 is different for different models, when the clip end 32 of the clip 30 corresponds to the distance, the fastener 60 can be worn through the clip 30. Between the two, and through the fastening screw 61 and the screw 62 to close each other, so that the clip end 32 is increased to apply force to the bearing 1 so as to extend into the distance, so that the clip end 32 is positioned at the bearing 1 to perform subsequent Unload the job.
