[0017] In the above scheme, the bottom of the guide rail main body 1 is provided with a support rod 21, and the bottom of the support rod 21 is provided with a base 22. By providing first track 11 and second track 12 on guide rail main body 1, and providing first recess 14 and second recess 15 below mobile seat 13 that cooperate with them, mobile seat 13 is stably clamped on guide rail main body 1, ensuring the stability of the linear guide rail mechanism during adjustment.
[0018] In the above scheme, a threaded hole is formed in the limit block 16, and a limit screw 17 is screwed into the threaded hole. The inner side of the limit screw 17 is movably connected with a clamping block 18. The lower portion of the clamping block 18 is provided with a clamping block 19, which is movably clamped in the movable slot 2 above the mobile seat 13. The user manually rotates the limit screw 17 to make the clamping block 19 at the bottom of the clamping block 18 move horizontally in the movable slot 2, thereby adjusting the distance between the two clamping blocks 18. This can meet the positioning needs of the inner equipment, further ensure the stability of the equipment, and enhance the use effect of the device.
