In this embodiment, the cylinder 41 and the piston rod 42 are generally commercially available locking cylinders. This is a conventional technology and is not a technical feature of this case. Those skilled in the art can infer the expansion based on the above description. Details, so I won’t elaborate.

The first resistance unit 5 is movably sleeved on the lower riser 31 of the stand unit 3, and is suitable for providing resistance to moving limbs, such as feet. The first resistance unit 5 includes a sliding group 51 movably sleeved on the lower riser 31, a resistance group 52 connected to the sliding group 51 and suitable for providing resistance, and covering the sliding group 51 and part A decorative cover 53 of the resistance group 52 (Figure 2).

The sliding group 51 has two sliding members 511 sliding on two opposite sides of the lower riser 31 and having a crotch shape, and a connecting member 512 connected to the sliding members 511 and the resistance group 52 and having a U shape. The connecting member 512 has two pivot seats 513 spaced apart.

The second resistance unit 6 is arranged at one end of the upper riser 32 away from the base unit 2 and is suitable for providing resistance to moving limbs, such as hands.

The adjusting unit 7 includes an operating member 71 pivoted between the pivot seats 513 and operable, a bolt 72 penetrating the operating member 71 and the pivot seats 513, and an elastic element 73.

The operating member 71 has an abutting surface 711 formed at one end and facing downward, and a pressing portion 712 opposite to the abutting surface 711 and capable of being operated. The operating element 71 is detachably coupled to the corresponding coupling portion 311, so that the first resistance unit 5 is blocked by the operating element 71 and the corresponding coupling portion 311 to obtain positioning. The operating member 71 can swing between a locked position (as shown in FIG. 3) and an unlocked position (as shown in FIG. 7) relative to the lower riser 31. In the locked position, the abutting surface 711 abuts against the corresponding joint portion When the blocking surface 312 of 311 is in the unlocked position, the abutting surface 711 is separated from the corresponding blocking surface 312.

The elastic element 73 is disposed between the operating member 71 and the connecting member 512 of the first resistance unit 5, and constantly generates a biasing force that displaces the abutting surface 711 of the operating member 71 toward the connecting portion 311.

Referring to FIGS. 3, 5 and 6, the resistance unit 5 is positioned by its own gravity when the operating member 71 abuts against the corresponding stop surface 312 with the abutting surface 711.

Thereby, when the height of the first resistance unit 5 is to be adjusted, the first resistance unit 5 can be pushed upward, and the operating member 71 can be driven so that the operating member 71 moves upward following the inclined surface 313 of the corresponding coupling portion 311. And in the process of displacement, it is forced by the inclination of the corresponding inclined surface 313 to overcome the biasing force of the elastic element 72 and swing from the locked position to the unlocked position. At this time, the abutting surface 711 will be separated from the corresponding The connecting portion 311 enables the first resistance unit 5 to slide on the lower riser 31 along the axis L with the sliding members 511 until the abutting surface 711 of the operating member 71 is displaced to the next connecting portion 311. Under the action of the biasing force of the elastic element 72, it displaces toward the corresponding coupling portion 311 and penetrates into the coupling portion 311. At the same time, under the force of the gravity of the resistance unit 5, the abutting surface 711 abuts against Corresponding to the blocking surface 312 of the coupling portion 311, the positioning is obtained.

3, 5, and 7, when the height of the first resistance unit 5 is adjusted, the pressing portion 712 of the operating member 71 can also be pressed, so that the operating member 71 overcomes the biasing force of the elastic element 72, and the The locked position swings to the unlocked position, whereby the operating member 71 can be separated from the corresponding coupling portion 311, so that the first resistance unit 5 can slide upward or downward along the axis L with the sliding members 511 The lower riser 31, when the abutting surface 711 of the operating member 71 is displaced to the corresponding coupling portion 311, only the pressing portion 712 needs to be loosened, and the operating member 71 can be subjected to the biasing force of the elastic element 72 again. It is inserted into the connecting portion 311, and under the action of the gravity of the resistance unit 5, the abutting surface 711 is again pressed against the blocking surface 312 of the corresponding connecting portion 311, and the positioning is obtained.

Referring to Figures 8 and 9, it is worth noting that when the abutting surface 711 of the operating member 71 abuts against the coupling portion 311 that defines the through hole 310, due to the lack of an inclined surface 313 capable of pushing the operating member 71 ( 5), and the operating member 71 is limited by the perforation 310 and cannot be separated from the coupling portion 311 that defines the perforation 310. Therefore, the operation can be driven only by pressing the pressing portion 712 of the operating member 71 The abutting surface 711 of the member 71 is separated from the corresponding joint 311.

Thereby, when the stand unit 3 rotates relative to the base unit 2 until the included angle with the base 21 is equal to 0 degrees, and the upper stand pipe 32 rotates relative to the lower stand pipe 31 to the included angle with the lower stand pipe 31 Is equal to 0 degrees, and when the upper riser 32, the lower riser 31 and the base 21 of the base unit 2 are superimposed from top to bottom, the operating member 71 can just be hidden in the lower riser 31 and the base 21 Between the bases 21, it is avoided that the first resistance unit 5 is displaced due to improper external force colliding with the first resistance unit 5.

Based on the above description, the advantages of the foregoing embodiments can be summarized as follows:

1. The present invention is able to make the first resistance unit 5 displaceable on the stand unit 3 through the design of the sleeve connection between the first resistance unit 5 and the stand unit 3, so as to meet the needs of different users. , Adjust the height.

2.
