DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] Insert the pin 10 on the surface of the protective cover 5 into the socket 301 to achieve the purpose of connecting the protective cover 5 with the positioning ring 3. At this time, the protective cover 5 protects the detection head 101 to prevent the detection head 101 from being damaged when the infrared spectrometer falls accidentally.

[0026] Two clamping blocks 4 symmetrically distributed up and down are fixedly connected to the circumferential side wall of the positioning ring 3, and a reinforcing component 6 for preventing the protective cover 5 from falling off is fixedly installed on the protective cover 5.

[0027] In addition, through the cooperation between the reinforcement component 6 and the clamping block 4, the tightness between the protective cover 5 and the positioning ring 3 is further improved to prevent the protective cover 5 from falling off.

[0028] The reinforcement component 6 includes a positioning block 61 fixed on the protective cover 5, and a guide rod 62 fixed on both sides of the positioning block 61. The other end of the guide rod 62 is fixedly connected to a stopper 65. A clamping strip 63 is slidably sleeved on the guide rod 62. One end of the clamping strip 63 has a clamping portion 631. A spring 64 is fixedly connected between the stopper 65 and the clamping strip 63. When the protective cover 5 and the positioning ring 3 are reinforced, the clamping portion 631 is clamped on the clamping block 4.

[0029] When installing the protective cover 5, it is first necessary to push the card strip 63 in the opposite direction, and then insert the pin 10 of the protective cover 5 into the socket 301. When the card strip 63 moves to the block 4, release the card strip 63. At this time, the spring 64 pulls the card strip 63 to move, and the two card strips 63 approach each other, and finally the clamping part 631 at the end of the card strip 63 contacts the block 4 to achieve buckling.

Therefore, the elastic band 8 is detachably mounted, and by unscrewing the bolts 9, the mounting block 7 can be separated from the grip arm 2 and the elastic band 8 can be removed.

[0032] The device needs to be operated by holding the grip arm 2. An elastic strap 8 is provided on the grip arm 2 to further fix the hand to prevent the spectrometer body 1 from falling off the hand and causing damage when operating the spectrometer body 1, thereby having a good safety protection effect.
