The first connection seat 21 is provided with a plurality of first external contact points 212 on the side away from the blocking column 11. Since the first external contact points 212 are electrically connected to the socket 211, the external test equipment can achieve electrical connection with the gun tip 50 through the first external contact points 212, thereby realizing the power-on test of the gun tip 50.

[0052] like Figure 6 and Figure 7 As shown, the plug circuit board processing area 30 is provided with a first quick-change sub-tray 31, and the first quick-change sub-tray 31 is recessed downward to form a first positioning groove 311. The plug circuit board 70 to be processed is placed in the first positioning groove 311, and the plug circuit board 70 can be processed by wave soldering, tinning, etc. in related processes.

[0053] The plug circuit board processing area 30 of the tray body 100 is provided with an installation slot 32 (such as Figure 5 As shown in the figure with reference numeral 32, a portion of the first quick-change sub-tray 31 sinks downward into the mounting groove 32. The mounting groove 32 can limit and position the horizontal position of the first quick-change sub-tray 31, while improving the efficiency of installing the first quick-change sub-tray 31 on the tray body 100.

[0054] like Figure 8 As shown, in this embodiment, the first quick-change sub-tray 31 can be quickly disassembled from the tray body 100, so as to achieve the change of type. Specifically, the first quick-change sub-tray 31 is compressed or loosened by the first clamping bolt 33, so as to achieve quick disassembly and assembly, wherein a plurality of first clamping bolts 33 are all threadedly connected to the tray body 100, and a first pressing piece 331 (semicircular) is arranged on the outer periphery of the first clamping bolt 33, and the first pressing piece 331 can press down the edge position of the first quick-change sub-tray 31, so as to fix the first quick-change sub-tray 31 on the tray body 100, and when the first quick-change sub-tray 31 needs to be replaced, it is only necessary to screw the first clamping bolt 33 upwards so that the first pressing piece 331 loosens the first quick-change sub-tray 31.

[0055] like Figure 8As shown, in some preferred embodiments, a telescopic limiting mechanism 34 for limiting the position of the plug circuit board 70 is disposed on the first quick-change sub-tray 31 , and a plurality of telescopic limiting mechanisms 34 are disposed in the first positioning groove 311 .

[0056] like Fig. 9 As shown, the telescopic limit mechanism 34 includes a guide block 341, a limit pressure block 342 and an elastic member 343; the guide block 341 is fixedly arranged in the first positioning groove 311, and the guide block 341 is provided with a guide slide groove 3411, the length direction of the guide slide groove is horizontal, at least a part of the limit pressure block 342 is slidably arranged in the guide slide groove along the horizontal direction, and the end of the limit pressure block 342 close to the center of the first positioning groove 311 is provided with an arc portion 3421, and the two ends of the elastic member 343 (such as a spring, etc.) respectively abut the guide block 341 and the limit pressure block 342, and the telescopic direction of the elastic member 343 is consistent with the sliding direction of the limit pressure block 342.

[0057] like Figure 8 and Fig. 9 As shown, when the plug circuit board 70 needs to be installed in the first positioning groove 311, the plug circuit board 70 is pressed downward into the first positioning groove 311. During this process, the edge position of the plug circuit board 70 contacts the arc portion 3421 of the limiting pressure block 342, and the plug circuit board 70 pushes the limiting pressure block 342 to slide in the guide groove (at this time, the limiting pressure block 342 gradually compresses the elastic member 343). When the plug circuit board 70 is pushed away and passes over the limiting pressure block 342 downward, the limiting pressure block 342 is reset (i.e., the limiting pressure block extends) under the drive of the elastic member 343, i.e., the lower plane of the limiting pressure block 342 can extend above the edge of the plug circuit board 70, thereby limiting the plug circuit board 70 from moving upward or being taken out.

[0058] like Fig.10 As shown, preferably, the limiting pressing blocks 342 of two adjacent telescopic limiting mechanisms 34 can be connected by a connecting rod 35, so as to ensure that the two limiting pressing blocks 342 move synchronously. When it is necessary to remove the plug circuit board 70, the staff only needs to push the connecting rod 35 to make the limiting pressing blocks 342 move out of position, so as to facilitate the removal of the plug circuit board 70. In this embodiment, by providing the telescopic limiting mechanism 34, the stability of the plug circuit board 70 in the first positioning groove 311 can be ensured, so as to facilitate its processing.

[0059] like Fig.11 and Fig.12As shown, the connecting plug test area 40 is provided with a second quick-change sub-tray 41, a socket 42 and a second connecting seat 43. The second quick-change sub-tray 41 is provided with a second positioning groove 411 which is recessed downward, and the connecting plug 80 can be arranged in the second positioning groove 411, and a placement position is provided for the connecting plug 80 through the second positioning groove 411. The socket 42 is provided on the tray body 100, and the socket 42 can be plugged and matched with the connecting plug 80. A plurality of second external contacts 431 are provided on the side of the second connecting seat 43 away from the socket 42, and the second external contacts 431 are electrically connected to the socket 42. When the connecting plug 80 is placed in the second positioning groove 411, the connecting plug 80 (the structure of the connecting plug is shown in Fig.13 As shown in the figure, the socket 42 can be inserted downward into the socket 42. Since the socket 42 is electrically connected to the second external contact point 431, an external testing device can perform a power-on test with the connecting plug 80 through the second external contact point 431.

[0060] like Fig.11 and Fig.12 As shown, the inner bottom surface of the second positioning groove 411 is provided with a matching hole 412 that passes downward through the second quick-change sub-tray 41, and the matching hole 412 corresponds to the socket 42 on the tray body 100 up and down, so when the connecting plug 80 is placed downward in the second positioning groove 411, the inserting teeth of the connecting plug 80 can pass through the matching hole 412 and be inserted into the socket 42. In this embodiment, by designing the matching hole 412, the connection between the connecting plug 80 and the socket 42 can be realized simultaneously when the connecting plug 80 is placed, thereby improving work efficiency.

[0061] like Fig.12 As shown, the second quick-change sub-tray 41 can be quickly disassembled and assembled on the tray body 100. The specific implementation method is: a plurality of second clamping bolts 44 are threadedly connected to the tray body 100, and a second clamping plate 441 (semicircular) is connected to the outer periphery of the second clamping bolt 44. When the second clamping bolt 44 is tightened downward, the second clamping plate 441 can clamp the edge position of the second quick-change sub-tray 41, thereby pressing the second quick-change sub-tray 41 onto the tray body 100. When the second quick-change sub-tray 41 needs to be replaced, only the second clamping plate 441 needs to be loosened.

[0062] like Fig.12 As shown, in some embodiments, preferably, an auxiliary positioning block is provided on the second quick-change sub-tray 41, and a U-shaped positioning groove 413 which is recessed downward is provided on the auxiliary positioning block, and the wire end 81 of the connecting plug 80 is arranged in the U-shaped positioning groove 413, and the position of the connecting plug 80 is further limited by the U-shaped positioning groove 413 to ensure its stability.

[0063] The above is only a specific implementation of the present application. Those skilled in the art can clearly understand that for the convenience and simplicity of description, the specific working processes of the systems, modules and units described above can refer to the corresponding processes in the aforementioned method embodiments, and will not be repeated here.
