## Abstract

A roaster structure with a cover supporting member for achieving secure angular positions includes a roaster body and a ceramic cover in addition to the cover supporting member for achieving secure angular positions. The cover supporting member for achieving secure angular positions includes: a lower supporting member fixedly provided on one side of the roaster body and having a first joining end and at least one limiting groove; an upper supporting member pivotally joined to the lower supporting member and having a second joining end; at least one position-limiting member fixed on the upper supporting member and slidably inserted into the at least one limiting groove; and an extensible and retractable bar joined between the two joining ends. The ceramic cover can be lifted open and closed with respect to the roaster body and secured at any angular position via the cover supporting member for achieving secure angular positions.

## Claims

### Claim 1

A roaster structure with a cover supporting member for achieving secure angular positions, comprising:
a roaster body formed as a bowl-shaped structure and having a hollow portion, the roaster body having a sidewall with a bottom-side opening;
the cover supporting member for achieving secure angular positions, which comprises:
a lower supporting member fixedly provided on a side of the roaster body and having a first joining end and at least one limiting groove;
an upper supporting member joined to the lower supporting member via a pivot shaft and having a second joining end;
at least one position-limiting member fixed on the upper supporting member and slidably inserted into the at least one limiting groove; and
an extensible and retractable bar having a first joining portion movably joined to the first joining end, the extensible and retractable bar having a second joining portion movably joined to the second joining end; and
a ceramic cover having an end joined to the upper supporting member such that the ceramic cover is able to be lifted open and closed with respect to the roaster body and secured at a plurality of positions via the cover supporting member for achieving secure angular positions.

### Claim 2 (depends on 1)

The roaster structure of claim 1, wherein the at least one position-limiting member comprises a locking bolt and a pressing and securing plate joined to the locking bolt, and the locking bolt is able to be turned so as to press the pressing and securing plate tightly against the lower supporting member and thereby secure the ceramic cover at an arbitrary angle.

### Claim 3 (depends on 1)

The roaster structure of claim 1, wherein the extensible and retractable bar comprises:
a spring; and
a spring holder comprising an extensible and retractable supporting rod and a pair of clamping plates provided respectively at two opposite ends of the extensible and retractable supporting rod, wherein the spring is mounted around the extensible and retractable supporting rod and is located between the pair of clamping plates, and the extensible and retractable supporting rod has the first joining portion, which is joined to the first joining end, and the second joining portion, which is movably joined to the second joining end.
