Abstract

A gas torch comprises a torch head assembly including a coupled base and a connected portion coupled to the outer periphery of the coupled base; and a joint assembly, which is coupled to the coupled base and adapted for connecting to a nozzle of a bottled gas tank, includes a first joint member and a second joint member communicating with the first joint member; wherein two fasteners are inserted through the first and second joint members and engaged with the coupled base of the torch head; wherein the joint assembly enables to connect the torch head assembly to different kinds of gas tanks.

Claims

1. A gas torch comprising:

a torch head assembly including a coupled base and a connected portion coupled to the outer periphery of the coupled base; and

a joint assembly, which is coupled to the coupled base and adapted for connecting to a nozzle of a bottled gas tank, includes a first joint member and a second joint member communicating with the first joint member, with the first and second joint members joined together in a tightly-coupled manner;

wherein the torch head assembly enables to connect to different kinds of gas tanks.

2. The gas torch as claimed in claim 1 further comprising an engagement plate including a mounted portion mounted onto the connected portion and an engaged portion extending from the mounted portion transversely, with the engaged portion outwardly tilted toward a direction which is opposite to a direction of the torch head assembly, with the joint assembly communicating the torch head assembly with the bottled gas tank, with the engagement plate restricted between the joint assembly and the torch head assembly, with a user'"'"'s hand being able to be placed between the engagement plate and the bottled gas tank for a firmly hold of the gas torch.

3. The gas torch as claimed in claim 2 wherein the torch head assembly further includes a tube formed on an end thereof and an adjusting button provided at another end thereof;

wherein a distance between the distal end of the engaged portion and the center of the gas torch is larger than a distance between the outer periphery of the bottled gas tank and the center of the gas torch or a distance between the distal end of the adjusting button and the center of the gas torch.

4. The gas torch as claimed in claim 2 wherein the torch head assembly includes a torch head and a casing covering on two sides of the torch head, with the coupled base transversely installed to the torch head, with the connected portion formed on the casing and corresponding to the coupled base.

5. The gas torch as claimed in claim 4 further comprising several limited protrusions formed on the outer periphery of the distal end of the connected portion, a flange defined on the inner periphery of the mounted portion and several notches formed on the flange and spaced from each other, with the notches inserted by the limited protrusions.

6. The gas torch as claimed in claim 2 further comprising a compartment defined between the engagement plate and the bottled gas tank, with a user'"'"'s hand being able to be placed in the compartment.

7. The gas torch as claimed in claim 6 wherein the bottled gas tank includes a neck connected a body of the bottled gas tank to the nozzle of the bottled gas tank, with the compartment defined between the neck and the engagement plate.

8. The gas torch as claimed in claim 2 further comprising a receptacle formed on the engaged portion for setting labels or trademarks thereupon.

9. The gas torch as claimed in claim 3 wherein two fasteners are inserted through the first and second joint members and engaged with the coupled base of the torch head.

10. The gas torch as claimed in claim 9 further comprising an abutted portion and a coupled portion defined on the bottom side of the coupled base, with the coupled portion protruding from the center of the abutted portion, and with two opposite coupled holes formed on the abutted portion and surrounding the coupled portion, with the first joint member having a through-hole mounted onto the coupled portion, with two fasteners inserted through the first and second joint members and engaged with the coupled holes of the torch head.

11. The gas torch as claimed in claim 10 wherein the bottled gas tank further includes an engaged disc surrounding the nozzle and having a gap opened outwardly, with a space defined between the nozzle and the engaged disc;

wherein the first joint member includes several combined portions and a block formed on a side thereof opposite to the coupled base, with the block forming with a slot;

wherein the second joint member includes several projections and several receptacles formed on the outer periphery thereof, with each receptacle defined between each two of the projections, with each receptacle inserted by the related one combined portion, with the combined portions and the projections abutted against the inner side of the space, with the block inserted through the gap and during rotating the second joint member, the slot is engaged with the engaged disc.

12. The gas torch as claimed in claim 10 wherein the bottled gas tank includes a threaded portion formed on the outer periphery thereof;

wherein the first joint member includes a combined portion formed on a side thereof opposite to the coupled base and the second joint member includes an inner threaded portion, which is formed inside thereof and engaged with the threaded portion of the bottled gas tank in a screw manner, and an abutted portion coupled to the combined portion of the first joint member.

13. The gas torch as claimed in claim 10 wherein the first joint member includes two limited holes formed thereon around the through-hole and the second joint member includes two engaged holes, with the fasteners inserted through the limited holes and the engaged holes.

14. The gas torch as claimed in claim 13 wherein the second joint member is able to rotate with respect to the first joint member via the fasteners moved along the limited holes of the first joint member.

15. The gas torch as claimed in claim 1 further comprising a channel formed in the center thereof and communicating with the bottled gas tank for gas passing through.

16. The gas torch as claimed in claim 14 wherein each of the limited holes is in form of a long groove.

17. The gas torch as claimed in claim 11 wherein an inner diameter of each combined portion is larger than an outer diameter of each receptacle and smaller than an outer diameter of each projection.

18. The gas torch as claimed in claim 11 wherein the first joint member has four combined portions and the second joint member has four projections and four receptacles.

19. The gas torch as claimed in claim 9, with the combined portions and the projections being flexible.

20. The gas torch as claimed in claim 19, wherein while in the second position of the first joint member, the combined portions, the projections and the space from a tightly-coupled combination.
