The cross rod fixing device is simple in structure, the height of the cross rod fixing device on the column can be conveniently and quickly adjusted, the teaching and training needs of the height of two cross rods can be met through one-time adjustment, and the cross rod fixing device is good in protectiveness and can be well used in physical education.

Description

Technical field [0001] The invention relates to a fixing device, in particular to a crossbar fixing device. Background technique [0002] In the process of high jump teaching and training, the height of the crossbar needs to be adjusted at any time. In the prior art, the high jump crossbar fixing device for training usually uses a casing set on the column to fix the crossbar support plate on the column. The casing is provided with Tighten the top wire. When adjusting the height of the cross bar, you need to loosen the top wire first, slide the casing to an appropriate height, and then screw the top wire to lock the casing on the column. Due to the height of the cross bar during training and teaching Adjustments are frequent, so the high jump crossbar fixing device using this casing structure is troublesome to operate, and it is easy to cause safety hazards due to students tripping on the rubber band and pulling the high jump frame down. It also makes the students lack of success ...
