[0031] The first embodiment, such as figure 2 As shown, the present invention constructs a christmas tree nozzle reading device, the nozzle includes a valve handwheel 1, the nozzle reading device includes a fixing device 2 fixed to the valve handwheel 1, a transmission device 3 connected with the fixing device 2, and The on-site display device 4 connected to the transmission device 3 and the supporting device 5 for supporting the transmission device 3 and the on-site display device 4 . Wherein, the rotation of the valve handwheel 1 can drive the transmission device 3 to rotate through the fixing device 2, and then drive the on-site display device 4 to display the rotation scale of the valve handwheel 1. What needs to be explained here is that the scale of the handwheel rotation is the grease nipple scale.
[0032] In this embodiment, the fixing device 2 includes a fixing clip, which is fixedly connected or detachably connected with the valve handwheel 1 and the reading devic...
