In view of the above, an object of the present invention is to provide a two-way finger expander, which has the advantages of two finger training methods.
The above utility model discloses an above-mentioned utility model purpose can realize through following technical scheme:
the bidirectional finger expander is characterized by comprising a supporting rod, wherein a first finger expanding part and a second finger expanding part are arranged on the supporting rod in a sliding manner;
the first finger-expanding part is in a cylinder shape, one end of the cylinder is provided with an opening for fingers to insert, and the end of the cylinder far away from the opening is sealed; the second finger expansion part is annular and is used for fingers to penetrate through and insert.
Through the technical scheme, when the bidirectional finger expander is used, the two finger expanders can be switched, and different finger exercises can be freely performed.
Further, a connecting portion is arranged between the first finger expansion portion and the second finger expansion portion, and the supporting rod penetrates through the connecting portion.
Through above-mentioned technical scheme, the bracing piece slides in the connecting portion, can adjust and expand and indicate the interval.
Furthermore, the first finger expansion part is provided with a screwing screw at one end close to the supporting rod, and the screwing screw is tightly abutted to the supporting rod.
Through above-mentioned technical scheme, the screw of screwing is loosened, can adjust and expand and indicate the interval, and when the screw of screwing is screwed, can prevent bracing piece and connecting portion relative slip.
Furthermore, one end of the opening of the first finger expansion part is in a circular arc shape concave shape in the direction parallel to the support rod.
Through above technical scheme, when the finger is crooked, with convex sunken phase-match, the reinforcing comfort.
Further, the wall thickness of the finger penetrating direction of the second finger expander decreases from the middle to the edge.
Through above technical scheme, when the finger is crooked, reinforcing comfort.
Compared with the prior art, the beneficial effects of the utility model are that:
the bracing piece is gone up to slide and is provided with first finger-expanding portion and second finger-expanding portion, and first finger-expanding portion is the drum shape, and drum one end opening supplies the finger to insert, and it is sealed that the opening one end is kept away from to the drum, and second finger-expanding portion is the ring form, supplies the finger to run through and inserts. When the bidirectional finger expander is used, the two finger expanders can be switched, and different finger exercises can be freely performed.

FIG. 2 is a schematic view of a finger of the present invention inserted into the first finger-expanding portion;
fig. 3 is a schematic view of the finger of the present invention inserted into the second finger-expanding portion.
Reference numerals: 1. a second finger expansion portion; 2. a first finger expansion portion; 3. a support bar; 4. a connecting portion; 5. and a limiting member.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and examples.
The bidirectional finger expander is characterized by comprising a support rod 3, wherein a first finger expanding part 2 and a second finger expanding part 1 are arranged on the support rod 3 in a sliding manner;
the first finger-expanding part 2 is in a cylinder shape, one end of the cylinder is opened for fingers to insert, and the end of the cylinder far away from the opening is sealed; the second finger-expanding part 1 is annular and is used for fingers to penetrate through.
Through the technical scheme, when the bidirectional finger expander is used, the two finger expanders can be switched, and different finger exercises can be freely performed.
Further, a connecting portion 4 is arranged between the first finger-expanding portion 2 and the second finger-expanding portion 1, and the support rod 3 penetrates through the connecting portion 4.
Through above-mentioned technical scheme, bracing piece 3 slides in connecting portion 4, can adjust and expand and indicate the interval.
Furthermore, a screwing screw is arranged at one end, close to the support rod 3, of the first finger expansion part 2, and the screwing screw is tightly abutted to the support rod 3.
Through the technical scheme, the screwed screw is loosened, the finger expansion distance can be adjusted, and the support rod 3 and the connecting part 4 can be prevented from sliding relatively when the screwed screw is screwed.
Furthermore, one end of the opening of the first finger expansion part 2 is recessed in an arc shape in a direction parallel to the support rod 3.
Through above technical scheme, when the finger is crooked, with convex sunken phase-match, the reinforcing comfort.
