[0026] The placement unit includes a support plate 301, a digital display instrument housing 302 and a chuck 303. The support plate 301 is fixedly connected to the inner wall of the shell 1. A groove is provided on the top of the support plate 301. The digital display instrument housing 302 is arranged inside the shell 1. The chuck 303 is fixedly connected to the bottom of the digital display instrument housing 302. The chuck 303 is engaged with the groove. The digital display instrument housing 302 can be moved to insert the chuck 303 into the groove to complete the preliminary installation of the digital display instrument housing 302.

[0027] The limiting unit includes a pressing plate 304, a sliding rod 305 and a connecting piece 306. The pressing plate 304 is arranged inside the shell 1. The outer wall of the pressing plate 304 is slidably connected to the inner wall of the shell 1. The pressing plate 304 can slide inside the shell 1. The bottom of the pressing plate 304 contacts the top of the support plate 301 and the top of the chuck 303 respectively. The sliding rod 305 is fixedly connected to the top of the pressing plate 304. The top of the sliding rod 305 penetrates the shell 1 and extends to the top of the shell 1.
