## Abstract

An extension-type holder comprising a cover, a movable base, a tube and an extensible rod assembly, the cover has an eccentric rod, the movable base has an eccentric pipe, a rotating joint is disposed between the extensible rod assembly and the tube, wherein the eccentric pipe can contain the eccentric rod, the tube can contain the movable base, a holding space can be formed between a cover and a movable base when the eccentric rod and the movable base is in an extending state.

## Claims

### Claim 1

An extension-type holder comprising:
a cover having an eccentric rod extending therefrom;
a movable base having an eccentric pipe extending therefrom, the eccentric rod being movably contained in the eccentric pipe;
a tube for containing the movable base, the movable base sliding within the tube;
an extensible rod assembly and a rotating joint between the extensible rod assembly and the tube;
wherein a holding space is formed between the cover and the movable base when the eccentric rod and the movable base are in an extending state.

### Claim 2 (depends on 1)

The extension-type holder of claim 1, wherein the eccentric rod has a block, a restoring spring is disposed between the block and an inner flange of the eccentric pipe, the eccentric rod has a non-circular cross section, and the shape of the inner flange is adapted to the cross section of the eccentric rod.

### Claim 3 (depends on 2)

The extension-type holder of claim 2, wherein a pair of replaceable positioning elements are respectively embedded on the cover and the movable base.

### Claim 4 (depends on 1)

The extension-type holder of claim 1, wherein a metal element is interposed in the cover and the eccentric rod, thereby increasing the strength of the eccentric rod.

### Claim 5 (depends on 1)

The extension-type holder of claim 1, wherein a metal element is insert molded in the cover and the eccentric rod, thereby increase the strength of the eccentric rod.

### Claim 6 (depends on 1)

The extension-type holder of claim 1, wherein the eccentric rod has a block, a plurality of restoring springs are disposed between the block and an inner flange of the eccentric pipe, the restoring springs are located on both sides of the eccentric rod, the eccentric rod has a non-circular cross section, and the shape of the inner flange is adapted to the cross section of the eccentric rod.

### Claim 7 (depends on 6)

The extension-type holder of claim 6, wherein a pair of replaceable positioning elements are respectively embedded on the cover and the movable base.
