Turning on the switch 3 starts the lamp body 2. After the ultraviolet light emitted by the lamp body 2 is irradiated on the banknote, the difference between the real banknote and the counterfeit banknote will appear due to the color difference. At the same time, the mark printed on the banknote using special fluorescent ink will emit fluorescence under the excitation of ultraviolet light, so that the anti-counterfeiting mark can be revealed; 2. Due to the presence of the battery 5 in the accommodating cavity 13, when the authenticity of the banknote needs to be verified and there is no power supply around, the battery 5 can start the lamp body 2 to judge the authenticity of the banknote, so that the identification instrument can be picked up and started in different usage environments to judge the authenticity of the banknote, making the banknote verification method more convenient and convenient, and the identification instrument is easy to carry; 4. Since the shell 1 is provided with a contact groove 15 below the lamp body 2, when using the identification instrument, the identification instrument can be held by holding the shell 1 with the palm of the hand and the fingers are located on each contact groove 15.

In summary, the charging port 7 and the battery 5 can both power the identification instrument, so the identification instrument can work with power in different usage environments; 2. When the identification instrument is wired and connected to the socket, the indicator light 8 can prompt the user that the power is turned on, making it more intuitive whether the power is turned on.

[0033] Preferably, the front housing 11 is provided with a first limiting portion 111 on the side of the lamp body 2, and the rear housing 12 is provided with a second limiting portion 121 on the side of the lamp body 2. The first limiting portion 111 is provided in an arc shape with an opening facing backward, and the second limiting portion 121 is provided in an arc shape with an opening facing forward. A first mounting groove 1271111 is provided in the first limiting portion 111, and a second mounting groove 1271211 is provided in the second limiting portion 121. The first limiting portion 111 and the second limiting portion 121 are both aligned with the lamp body 2 toward the accommodating cavity 13. Since the first limiting portion 111 of the front shell 11 and the second limiting portion 121 of the rear shell 12 are both against the lamp body 2, after the lamp body 2 is installed into the front shell 11 and the rear shell 12 to complete the connection between the front shell 11 and the rear shell 12, the lamp body 2 will not be separated from the outer shell 1 due to the action of the first limiting portion 111 and the second limiting portion 121. When the lamp body 2 is in working state, the ultraviolet light can pass through the first mounting groove 1271111 and the second mounting groove 1271211 downward to distinguish the authenticity of the banknotes.

[0034] In addition, the front shell 11 is provided with a positioning column 112 protruding rearward, and the length direction of each positioning column 112 extends forward and backward. The rear shell 12 is provided with a positioning groove 122 corresponding to each positioning column 112. The bottom of the rear shell 12 is provided with a rear installation plug block 123 protruding forward. The rear shell 12 is provided with a rear installation slot 124 above the rear installation plug block 123. The front shell 11 is provided with a front installation slot 114 corresponding to the rear installation plug block 123. The front shell 11 is provided with a front installation plug block 113 for inserting the rear installation slot 124 above the front installation slot 114. The bottom surface of the front installation plug block 113 is against the top surface of the rear installation plug block 123. 1. Due to the front shell 11 and the rear During the installation of the shell 12, the positioning column 112 protruding backward of the front shell 11 can be inserted into the corresponding positioning groove 122 to determine the relative position of the front shell 11 and the rear shell 12 in the front-to-back direction; 2. When the rear installation block 123 is located in the front installation slot 114, and the front installation block 113 is located in the rear installation slot 124, at this time, in the absence of external force, the front installation block 113 cannot pass downward over the rear installation block 123, thereby realizing the relative position of the front shell 11 and the rear shell 12 in the up and down direction. To sum up, the bottom of the front shell 11 and the rear shell 12 will not separate without the action of external force, which provides convenience for the subsequent fixation of the front shell 11 and the rear shell 12.

[0035] Preferably, the front mounting block 113 includes a front guide surface 1131, and the front guide surface 1131 is inclined from top to bottom and from rear to front. Since the front guide surface 1131 is inclined, when the front mounting block 113 is inserted into the rear mounting slot 124, the rear end surface of the front mounting block 113 can enter the rear mounting slot 124 more smoothly due to the setting of the front guide surface 1131.

[0036] Among them, the top of the front shell 11 is provided with an upper mounting plug block 115 protruding backward, and the top of the rear shell 12 is provided with an upper mounting slot 125 corresponding to the upper mounting plug block 115, and a first limiting plug block 117 is protrudingly provided on the upper mounting plug block 115, and the first limiting plug block 117 is arranged in an arc shape with an opening inserted downward, and the rear shell 12 includes an upper matching plug block 129 located above the upper mounting slot 125, and a limiting slot 1291 for the limiting plug block to be inserted is arranged in the upper matching plug block 129, and the rear shell 12 is provided with a second limiting plug block 126 with an opening facing upward at the front side of the upper mounting slot 127. 1. When the front shell 11 and the rear shell 12 are connected together, the first limiting plug block 117 on the upper mounting plug block 115 of the front shell 11 needs to be forced to cross the second limiting plug block 126 backward before entering the limiting slot 1291. Similarly, when the front shell 11 and the rear shell are connected together, 12 needs to be separated, the first limiting shell 11 of the front shell 11 needs to be forced to pass over the second limiting plug block 126 forward to achieve the separation of the front shell 11 and the rear shell 12; 2. Since the first limiting plug block 117 is in an arc shape with an opening facing downward, and the second limiting plug block 126 is in an arc shape with an opening facing downward, the highest point of the first limiting plug block 117 squeezes the lowest point of the second limiting plug block 126 to smoothly achieve the first limiting plug block 117 to forcefully pass over the second limiting plug block 126 backward to achieve cooperation with the limiting slot 1291, or the first limiting plug block 117 passes over the second limiting plug block 126 forward to achieve separation from the limiting slot 1291; In summary, in the absence of external force, the first limiting plug block 117 will not be separated from the limiting slot 1291, so that the upper side will not be easily separated when the front shell 11 and the rear shell 12 are connected, which provides convenience for the subsequent fixation of the front shell 11 and the rear shell 12.

[0037] Among them, the front shell 11 is protrudingly provided with a positioning bar 116 above the front mounting plug-in block 113, and the cover plate 14 is protrudingly provided with a plurality of positioning blocks 141 corresponding to the positioning bar 116, and each positioning block 141 is arranged at intervals on the cover plate 14 along the up and down direction, and the positioning bar 116 is provided with a positioning slot 1161 corresponding to each positioning block 141, and a disassembly plate 145 is protrudingly provided on the other side of the cover plate 14, and the disassembly plate 145 is protrudingly provided with a disassembly plug-in block 142 toward the rear, and a mounting groove 127 for the cover plate 14 to be installed is provided in the rear shell 12, and the rear shell 12 is provided with a disassembly slot 128 corresponding to each disassembly plug-in block 142, 1. When the cover plate 14 is installed When it reaches the installation groove 127 of the rear shell 12, the positioning blocks 141 on the cover plate 14 will fall into the corresponding positioning slots 1161 on the positioning strip 116, and the disassembly and assembly block 142 on the disassembly and assembly plate 145 on the other side will be installed into the disassembly and assembly slot 128. Since one part of the cover body is located in the front shell 11 and the other part is located in the rear shell 12, the cover body further improves the stability of the connection between the front shell 11 and the rear shell 12 while completing the installation; 2. Since the rearward projection of the battery 5 falls on the cover plate 14, the battery 5 can be disassembled and assembled by removing the cover plate 14, and the battery 5 can be isolated from the outside by installing the cover plate 14 again.

[0038] Preferably, the cover plate 14 is provided with a contact groove 143 which is recessed forward, and the cover plate 14 is provided with a plurality of contact strips 144 in the contact groove 143. Due to the arrangement of the contact strips 144 on the cover plate 14, applying force to the contact strips 144 can cause the cover plate 14 to deform forward, thereby causing the disassembly and assembly block 142 to move forward from the disassembly and assembly slot 128. At this time, the positioning block 141 is removed from the positioning groove 122 and the cover plate 14 is moved toward the side of the positioning block 141 to remove the cover plate 14 to achieve replacement of the battery 5.

[0039] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
