[0046] Specifically, the difference of a semi-automatic liquid oxygen vaporization oxygen supply device provided in the second embodiment of the present application is that for a semi-automatic liquid oxygen vaporization oxygen supply device, a base 8 is provided at the bottom of the outer surface of the mounting frame 1, a placement groove 21 is opened in the middle of the top of the base 8, communication holes 11 are opened on both sides of the outer surface of the base 8, a sliding cavity 12 is opened in the middle of the inner cavity wall of the communication hole 11, elastic devices 13 are provided on both sides inside the sliding cavity 12, a limiting device 14 is sleeved on the outer surface of the elastic device 13, and clamping grooves 20 are opened on both sides of the outer surface of the mounting frame 1.

[0047] Support devices 15 are fixedly installed around the bottom of the base 8, limiting rods 17 are fixedly installed on both sides inside the support device 15, and a moving device 18 is fixedly installed in the middle of the support device 15.

[0059] Compared with the related art, a semi-automatic liquid oxygen vaporization oxygen supply device provided by the present invention has the following

[0060] Beneficial effects:

[0061] The present invention provides a semi-automatic liquid oxygen vaporization oxygen supply device.
