The sliding base 13 is provided with a limiting pin 30 for limiting the rotation of the rotating hook 14, the limiting pin 30 is sleeved with a spring 31, and the spring 31 is limited and installed through a snap spring 32.

When the device is used for a Smith machine, the plug pins 7 on the sliding sleeves 10 are pulled out to adjust the sliding sleeves 10 at two sides to the uppermost ends, then the limiting pins 30 are pressed to rotate the rotating hooks 14 to enable the grooves of the rotating hooks 14 to face upwards, then the long barbell bars 38 are installed, and the key grooves on the long barbell bars 38 are aligned with the flat keys 39 of the rotating hooks 14, so that the long barbell bars 38 and the rotating hooks 14 can rotate synchronously. The stop pin 30 is then pressed, the rotating hook 14 is rotated up to lock the long barbell bar 38, and the safety stop 12 is adjusted to the appropriate gear, which converts the device into a smith machine. As shown in fig. 9, the adjusting tube 9 is at a certain angle with the left frame 1 and the right frame 3, so that the adjusting tube 9 can be ensured to be parallel to the long barbell bar 38 on the side where the second positioning hole 902 is located without changing the opening angle of the left frame 1 and the right frame 3, and the rotating hook 14 can be smoothly hooked into the second positioning hole 902.

When the device needs to be converted into a small bird trainer for use, the safety limit seat 12 is adjusted to the lowest end, then the limit pin 30 is pressed down, the rotating hook 14 is rotated to enable the groove of the rotating hook 14 to face upwards, then the long barbell rod 38 is taken out, the rotating hook 14 is rotated to the side opposite to the movable pulley 16 at the back, the short barbell rod 42 is installed, then the limit pin 30 is pressed, the rotating hook 14 is rotated to lock the short barbell rod 42, then the lock hook 43 on the movable pulley 16 is hooked on the hook piece 41, and the device is converted into the small bird trainer.

Preferably, the left frame 1 and the right frame 3 are connected through the rear frame 2, the left frame 1 and the right frame 3 are hinged to the left side and the right side of the rear frame 2 through hinged supports 5 respectively, the tops of the left frame 1 and the right frame 3 are connected through a detachable upper cross beam 8, and the bottoms of the left frame 1 and the right frame 3 are connected through a detachable lower cross plate 4. The left frame 1 and the right frame 3 are rigidly connected through the upper cross beam 8 and the lower cross plate 4, so that the whole frame cannot rotate and shake.

Preferably, the top of the left frame 1 is provided with a first clamping seat 29 with an open chute, the right frame 3 is provided with a second clamping seat 26 with a closed chute, one end of the upper cross beam 8 is provided with a hole and can be installed in the second clamping seat 26 through a pin 2601, the pin 2601 is inserted and then is limited and fixed by a gasket 2602 and a split pin 2603, and the pin 2601 can rotate after sliding up. The other end of the upper beam 8 is provided with a cylindrical pin 25 clamped in the open inclined groove.

When the equipment is installed, the cylindrical pin 25 is firstly clamped into the chute, the upper cross beam 8 is forced to enable the cylindrical pin 25 to move downwards along the chute, and at the moment, the end face of the upper cross beam 8 can prop against the plane of the first clamping seat 29. When the downward pressure is continued, the inclined groove still gives a force to the forward top of the cylindrical pin 25. However, the upper cross member 8 has already been pushed against the plane of the first engagement seat 29, and continuing forward only causes the plane to be pushed more tightly, so that the cylindrical pin 25 is engaged in the inclined groove. Then the chutes at the two ends of the lower cross plate 4 are inserted into the position-locking pins 27 at the two ends, the lower cross plate 4 will push forward along the chutes, and the left frame 1 and the right frame 3 will be spread outward by the lower cross plate 4 as the left frame 1 and the right frame 3 splay forward.
