[0006] Furthermore, an inspection door is provided on the front outer wall of the chassis, and a heat dissipation port is provided on the rear outer wall of the chassis.

[0007] Furthermore, the ends of the support frame are fixedly connected with slides, the ends of the slides are fixedly connected to the support frame, and a plurality of L-shaped guide grooves are provided on both sides of the inner wall of the chassis corresponding to the slides.

[0008] Furthermore, the slide plate is located at the short side of the L-shaped guide groove and fits therewith, and the width of the long side of the L-shaped guide groove is the same as the width of the slide plate.

[0009] Technical effects and advantages of the utility model:

[0010] 1. The utility model presses the limit blocks in the support frame to make them enter the long grooves, that is, the limit blocks drive the slider to move inward along the slide groove and compress the spring, and then the transceiver is aligned with the groove of the support frame and inserted inward. When the transceiver reaches the end of the groove, the limit block is no longer blocked by the transceiver and is ejected under the action of the spring, that is, the slider drives the limit block to pop outward along the slide groove until the limit block fits with the end of the transceiver, thereby realizing the rapid installation of the transceiver and the simple structure is convenient for disassembly.

[0011] 2. The utility model lifts the support frame upward, that is, the support frame and the slide move upward along the short side of the L-shaped guide groove, and then pulls the support frame outward, that is, the support frame and the slide move outward along the long side of the L-shaped guide groove, until the slide moves out of the L-shaped guide groove, and then inserts the slide into the L-shaped guide groove whose position needs to be adjusted as needed, and then installs the transceiver in the support frame, thereby realizing the adjustment of the transceiver position and improving the application range of the device.

A plurality of L-shaped guide grooves 3 are provided on both sides of the inner wall of the chassis 1 corresponding to the slide plates 8. The slide plates 8 are located at the short sides of the L-shaped guide grooves 3 and are attached thereto. The width of the long sides of the L-shaped guide grooves 3 is the same as the width of the slide plates 8. When it is necessary to adjust the position of the support frame 4, it is only necessary to lift the support frame 4 upward, that is, the support frame 4 and the slide plate 8 move upward along the short sides of the L-shaped guide grooves 3, and then pull the support frame 4 outward, that is, the support frame 4 and the slide plate 8 move outward along the long sides of the L-shaped guide grooves 3 until the slide plate 8 moves out of the L-shaped guide grooves 3, and then insert the slide plate 8 into the L-shaped guide grooves 3 whose positions need to be adjusted according to the needs, and then install the transceiver 6 in the support frame 4, that is, the adjustment of the position of the transceiver 6 is realized, and the application range of the device is improved.
