[0007] Preferably, the groove cavity is designed and formed as a through groove, which is formed after the strong magnet and the end cover are assembled at both ends of the guide rail extension.
[0008] Preferably, the guide rail extension is provided with a positioning groove for positioning and assembling the end cover.
[0009] Preferably, the end cover is integrally formed with a positioning column to be embedded in the guide rail extension piece.
[0010] Preferably, the positioning frame is formed with auxiliary holes and internal thread holes for assembling sensors and fasteners.
[0011] Preferably, a rubber pressing sheet is disposed at the end of the fastener.
[0012] Preferably, the bottom of the inner cavity of the groove cavity is designed to be flat.
[0013] Preferably, the size of the inner hole of the positioning frame for the guide rail extension piece to be inserted should be greater than or equal to the size of the guide rail extension piece.
[0014] Compared with the prior art, the advantages of the utility model are: the utility model is fixed on the mechanical equipment through strong magnets. Since most of the mechanical equipment is made of metal, the utility model can achieve on-demand fixed-point fixation based on strong magnets. Such a setting can adsorb the utility model on the required position as needed and firmly. The threaded connection adjustment and fixation based on the fasteners are also easy to operate. The utility model effectively reduces the probability of crushing the mold and reduces the production cost. BRIEF DESCRIPTION OF THE DRAWINGS
