[0030] like Figure 1-Figure 4 As shown, the reflective component 11 includes: a reflective slide groove 111, which is opened on the device body 100; a rotating driving member a112, which is installed on the device body 100; a screw 113, which is installed on the output end of the rotating driving member a112; a reflective slider 114, which is threadedly connected to the screw 113; and a reflective plate 115, which is detachably installed on the top of the reflective slider 114.

[0031] like Figure 5-Figure 6As shown, a threaded hole 1151 is provided at the bottom of the reflective plate 115 , a mounting hole 1141 is provided in the reflective slider 114 , and a bolt 116 threadedly connected to the threaded hole 1151 is provided in the mounting hole 1141 .

[0032] The screw rod 113 includes a threaded section 1131 and a circular shaft section 1132. A slot 1133 is provided in the circular shaft section 1132. A fixing plate 117 is installed at the bottom of the device body 100. A mounting slot 1171 is provided on the fixing plate 117. A fixing sleeve 118 is installed in the mounting slot 1171. A blocking block 119 is rotatably provided on the fixing sleeve 118. The blocking block 119 is inserted into the slot 1133.

[0033] like Figure 3 As shown, the distance testing component 12 includes: a U-shaped frame 121, which is mounted on the device body 100, and an avoidance groove 1211 is opened in the U-shaped frame 121; a laser slider 122, which is slidably mounted on the U-shaped frame 121; a linear driving member b123, which is mounted on the laser slider 122; a laser reflector 124, which is mounted on the output end of the linear driving member b123; a side laser emitter 125, which is mounted on the laser reflector 124; a side laser sensor 126, which is mounted on the laser reflector 124; and a top laser sensor 127, which is mounted on the top of the laser reflector 124.

The width of the coded object is accurately measured by the side laser emitter 125 and the side laser sensor 126. Then, the linear drive c128 drives the laser slider 122 to move in the U-shaped frame 121, and is started by the top laser sensor 127 to move from one end of the coded object to the other end. From the time when the top laser sensor 127 detects that the laser is blocked by the coded object to the time when it moves to the other end and re-detects the upper surface of the device body 100, it is accurately detected by the top laser sensor 127, so as to accurately measure the length of the coded object, and the length and width of the coded object are accurately measured by the set distance test component 12.

[0037] It should be noted that: when the reflective slider 114 needs to be removed, use a hex wrench to remove the bolt 116 in the mounting hole 1141. At this time, the reflective slider 114 and the reflective plate 115 are separated, and the rotating driving member a112 drives the screw 113 to rotate, while driving the reflective slider 114 to move horizontally in the reflective slide groove 111 until the reflective slider 114 moves from the threaded section 1131 to the circular shaft section 1132. At this time, pull the pull ring 120 to remove the fixing sleeve 118 and the block 119, and the block 119 leaves the slot 1133. At this time, the reflective slider 114 can be removed from the circular shaft section 1132, which is convenient for removing the reflective slider 114 for maintenance or replacement.
