End engages with the preset any sawtooth catch of pedestal horizontal ends；Foot is equipped in the middle part of described higher one end of arc frame to hang, it is described to face upward
The crouched side of sitting frame is slidably fitted with a supporting rod, and optoelectronic switch, the upper end of the supporting rod are equipped on the supporting rod
Equipped with counter, the optoelectronic switch is electrically connected with the counter；The counter is equipped with the display for display number
Shield, reset button is additionally provided on the counter.
Further, the side of the exerciser for erecting from lying is equipped with an one slide rail, and the extending direction of the sliding rail is faced upward with described
Crouched sitting frame extending direction it is identical, the supporting rod is slidably mounted on the sliding rail；The lower end of the supporting rod is equipped with one
Pulley, the sliding rail are equipped with a sliding slot, and the extending direction of the sliding slot is identical as the extending direction of the sliding rail, the pulley
Constraint is mounted in the sliding slot.
Further, further include buzzer, the buzzer is electrically connected with optoelectronic switch.
Further, further include safety supporting rod, described safety supporting rod one end is welded in the plank of pedestal vertically upward
Lower part, earthward direction extends the other end.
The utility model has an advantageous effect in that compared with prior art：The utility model physical education is counted with automatic
Sit-up device solves existing sit-up movement and counts the technical problems such as inaccuracy, and the utility model physical education is with automatically
Automatic counting and sounding reminding can be realized by counting sit-up device, and counting is accurate, height-adjustable, be had a wide range of application, significantly
Improve the effect of exercise, and achieved the purpose that test.
