[0008] Preferably, the rod walls at both ends of each rotating shaft are movably sleeved with torsion springs, and both ends of each torsion spring are fixedly connected to the U-shaped plate and the side wall of the corresponding rotating shaft.

[0009] Preferably, two fixing plates are symmetrically fixed on the outer wall of the U-shaped plate, a limiting rod is movably penetrated inside each of the fixing plates, a limiting groove is provided on the side wall of each rotating shaft, and the two limiting rods are matched with the corresponding limiting grooves respectively.

[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0021] The utility model embodiment discloses a gas cylinder valve hand wheel.

[0022] The utility model provides Figure 1-2 The gas cylinder valve handwheel shown in the figure comprises a knob 1, a U-shaped plate 2 is fixedly provided on the surface of the knob 1, two telescopic rods 3 are symmetrically provided inside the U-shaped plate 2, the opposite ends of the two telescopic rods 3 are fixedly sleeved with a rotating shaft 4, and the rod walls at both ends of each rotating shaft 4 are rotatably connected to the side wall of the U-shaped plate 2. By utilizing the two rotating shafts 4 and the corresponding telescopic rods 3, the two telescopic rods 3 can be opened before the driving knob 1 is rotated to achieve the adjustment of the driving force arm, thereby achieving labor-saving driving.

[0023] like Figure 2 As shown, the rod walls at both ends of each rotating shaft 4 are movably sleeved with torsion springs 5, and the two ends of each torsion spring 5 are fixedly connected to the U-shaped plate 2 and the side walls of the corresponding rotating shaft 4. By utilizing the set torsion springs 5, the corresponding rotating shaft 4 can be driven to rotate by the elastic force of the torsion springs 5, so that the corresponding telescopic rod 3 can be stably stored inside the U-shaped plate 2 without external driving force.

[0024] like Figure 2 As shown, two fixing plates 6 are symmetrically fixed on the outer wall of the U-shaped plate 2, and a limiting rod 7 is movably penetrated inside each fixing plate 6. A limiting groove is provided on the side wall of each rotating shaft 4, and the two limiting rods 7 are respectively matched with the corresponding limiting grooves. By utilizing the two limiting rods 7 and the limiting grooves provided on the side walls of the two rotating shafts 4, the rotation of the corresponding rotating shaft 4 can be limited after the two limiting rods 7 are plugged into the corresponding limiting grooves, thereby avoiding driving the rotating shaft 4 to rotate under the elastic force of the corresponding torsion spring 5, so that the user can drive the knob 1 to rotate through the corresponding telescopic rod 3.

[0025] like Figure 1-2 As shown, the surfaces of the two telescopic rods 3 are fixedly sleeved with anti-skid rubber sleeves 8. The anti-skid rubber sleeves 8 can increase the friction force on the surfaces of the corresponding telescopic rods 3, thereby facilitating operation by users.

[0026] like Figure 2 As shown, a driving block 9 is fixedly provided at one end of the two limiting rods 7 close to each other. The driving block 9 provided at the end of the limiting rod 7 can facilitate pulling the limiting rod 7 to move.

[0027] like Figure 2 As shown, the rod wall of each limiting rod 7 is fixedly sleeved with an annular plate 10, and a spring 11 is fixedly connected between each annular plate 10 and the corresponding fixed plate 6. Each spring 11 is movably sleeved with the rod wall of the corresponding limiting rod 7. By utilizing the set annular plates 10 and springs 11, the annular plates 10 can be squeezed by the elastic force of the springs 11, so that the annular plates 10 drive the limiting rods 7 to maintain a tendency to move under the elastic force of the springs 11, and then can automatically insert into the corresponding limiting groove when the end of the limiting rod 7 matches the position of the corresponding limiting groove.

[0028] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
