[0022] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0023] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0024] like Figure 1As shown, a handheld gas torch comprises a housing 1 with upper and lower openings, a handpiece 2 with an upper opening, an upper connecting piece 3 and a lower connecting piece 4.

[0025] The upper connecting member 3 includes an upper cylindrical seat portion 31 and two hooks 32. The hooks 32 include a circular arc plate portion 321 and a circular arc hook portion 322. The outer diameter of the circular arc plate portion 321 is smaller than the outer diameter of the upper cylindrical seat. The hooks 32 are provided at the lower end of the upper cylindrical seat portion 31.

[0026] The lower connecting member 4 includes a lower cylindrical seat portion 41, an axial introduction groove 42, and an axial plate groove 43 and a hook groove 44 arranged above and below. One end of the axial plate groove 43 and the hook groove 44 is connected to the axial introduction groove 42;

[0027] The upper cylindrical seat portion 31 is inserted into the lower end of the housing 1 and fixed, and the lower cylindrical seat portion 41 is inserted into the upper end of the handpiece 2 and fixed; the arc-shaped plate portion 321 cooperates with the axial plate groove, and the arc-shaped hook portion 322 is locked with the hook groove 44;

[0028] Figure 2 、 Figure 3 The shell 1 and the hand piece 2 of the utility model are in a fixed connection state. In the fixed connection state, hold the hand piece 2 by hand, rotate the shell 1 in the clockwise direction, and the upper connecting piece 3 rotates together with the shell 1; the arc-shaped hook portion 322 enters the axial guide groove 42 and separates from the axial plate groove 43 and the hook groove 44 respectively; the shell 1 moves upward to separate the shell 1 and the hand piece 2; due to the elasticity of the arc-shaped plate portion 321, the friction between the arc-shaped plate portion 321 and the axial plate groove 43 effectively prevents loosening.

[0029] As a further improvement of the present invention: the upper cylindrical seat portion 31 is provided with an upper axial glue-containing groove 311 and an upper circumferential glue-containing groove 312 intersecting with each other.

[0030] The lower cylindrical seat portion 41 is provided with a lower axial glue-containing groove 411 and a lower circumferential glue-containing groove 412 intersecting with each other.

[0031] The upper cylindrical seat portion 31 and the lower cylindrical seat portion 41 are respectively bonded to the housing 1 and the handpiece 2 by glue;

[0032] The depth of the upper axial glue-containing groove 311 is greater than the depth of the upper circumferential glue-containing groove 312;

[0033] The depth of the lower axial glue containing groove 411 is smaller than the depth of the lower circumferential glue containing groove 412 .

[0034] The upper connecting member 3 and the lower connecting member 4 are made of plastic material.

[0035] It also includes a magnetic attraction component, which includes an N magnet 51 and an S magnet 52, or the magnetic attraction component includes a magnet and a magnetic conductive metal part;
