The dust scraper is fixedly connected with the top of the cam, and the dust scraper is in contact with the outer wall of the guide rod. The lower end of the positioning block is installed on the chassis assembly tray, and at least two positioning slots are provided on the positioning block along the direction in which the linear slide rail extends. The positioning handle is rotatably connected with the cam through a pin shaft, and the end of the positioning handle can be clamped in any one of the positioning slots.
[0005] Preferably, the dust-proof scraper is in the shape of an annular structure.
[0006] Preferably, the two linear slide rails extend in the same direction and are vertically spaced apart from each other.
[0007] Preferably, a retaining spring is also included. A retaining spring is installed inside the support at the upper end of the slide groove, and the retaining spring is used to fix the linear bearing.
[0008] Beneficial effects of the utility model:
[0009] The worker lifts the positioning handle and pushes the support to move along the linear slide rail to another positioning slot position of the positioning block, presses down the positioning handle, and the positioning handle is re-slotted into another positioning slot to adjust the entire floating positioning mechanism, so that multiple models can be produced on the same production line. BRIEF DESCRIPTION OF THE DRAWINGS
