[0029] like Figure 3 and Figure 4 As shown, the inner cavity of the shell 1 is provided with a sliding assembly 3, and the sliding assembly 3 includes a placement box 31 and a limiting track 35. The bottom of the placement box 31 is fixedly connected to the bottom of the inner surface of the shell 1, and the bottom of the limiting track 35 is fixedly connected to the bottom of the inner surface of the shell 1. The bottom of the inner surface of the placement box 31 is fixedly connected to two symmetrically distributed support blocks 32, and the tops of the two support blocks 32 are commonly fixedly connected to a fixing plate 1 33, and the inner surface of the limiting track 35 is slidably connected to a latch assembly 34, and a spring 1 36 is fixedly connected between the front end of the latch assembly 34 and the front part of the inner surface of the limiting track 35;

[0030] The sliding latch assembly 34, at this time, the wedge block 1 342 passes through the hole groove on the surface of the fixed plate 1 33, and during the sliding of the wedge block 1 342, the inclined surface of the wedge block 1 342 will squeeze the inclined surface of the wedge block 2 44, so that the wedge block 2 44 moves upward to compress the spring, and the wedge block 2 44 slides on the top of the wedge block 1 342, and the wedge block 2 44 is locked and fixed when it slides into the limiting groove 346. When it needs to be unlocked, just put a magnet on the top of the protective shell 1 41 to attract the spring 2 42, so that the sleeve 43 drives the wedge block 2 44 to move upward, so that the wedge block 2 44 is separated from the limiting groove 346, thereby releasing the lock on the wedge block 1 342, and then slide the slider 1 341.

[0031] like Figure 5 As shown, the latch assembly 34 includes a slider 341, the bottom of which is slidably connected to the bottom of the inner surface of the limiting track 35, the top of the slider 341 is fixedly connected with a wedge block 342, the top of the wedge block 342 is fixedly connected with a fixing plate 343, the top of the fixing plate 343 is fixedly connected with a slider 344, the front end of the slider 344 is fixedly connected with a baffle 345, a limiting groove 346 is provided on the rear side of the top of the wedge block 342, the baffle 345 can prevent dust from entering the device during the sliding process of the slider 344, thereby affecting its use, and the top of the slider 344 is also provided with anti-slip texture to facilitate operation by the staff.

[0032] like Figure 6 and Figure 7 As shown, a locking assembly 4 is provided on the top of the sliding assembly 3, and the locking assembly 4 includes a protective shell 1 41, the bottom of the protective shell 1 41 is fixedly connected to the top of the placement box 31, a spring 2 42 is fixedly connected to the top of the inner surface of the protective shell 1 41, a sleeve 43 is fixedly connected to the bottom of the spring 2 42, a wedge block 2 44 is fixedly connected to the bottom of the sleeve 43, and the sleeve 43 and the wedge block 2 44 pass through the top of the placement box 31 and extend into the inner cavity of the placement box 31;

[0033] In this solution, both the sleeve 43 and the spring 42 are metal structures, which are convenient for subsequent magnet adsorption. When the magnet is needed to unlock, the magnet needs to be placed on the top of the protective shell 41 to attract the spring 42 and the sleeve 43 to compress the spring 42 upward. During this process, the wedge block 44 will gradually disengage from the limit groove 346, thereby achieving the purpose of unlocking.

[0034] like Figure 3 , Figure 4 and Figure 8As shown, the left end of the shell 1 is fixedly connected with a pull rope assembly 5, and the pull rope assembly 5 includes a protective shell 2 51, the right end of the protective shell 2 51 is fixedly connected to the left end of the shell 1, the rear side of the inner surface of the protective shell 2 51 is rotatably connected with a wire drum 52, the front part of the wire drum 52 is fixedly connected with a rotating shaft 53, and the front part of the rotating shaft 53 is fixedly connected with a knob 54, the right end of the shell 1 is fixedly connected with a fixed block 1 55, the inner surface of the fixed block 1 55 is slidably connected with a fixed block 2 56, a spring 3 57 is fixedly connected between the left end of the fixed block 2 56 and the left end of the inner surface of the fixed block 1 55, the outer surface of the wire drum 52 is wound with a soft wire, and the tops of the fixed blocks 1 55 and 2 56 are both provided with two threading holes that pass through the bottom;

[0035] During use, it is only necessary to pull the soft cord, at which time the soft cord will stretch, and then the soft cord is wrapped around the product, and then the fixing block 2 56 is pressed to make the threading holes of the fixing block 1 55 and the fixing block 2 56 coincide with each other, and the soft cord is passed through the threading hole, and then the fixing block 2 56 is released. At this time, the fixing block 2 56, under the action of the spring 3 57, makes the threading hole of the fixing block 2 56 deviate from the threading hole of the fixing block 1 55, so as to achieve the purpose of clamping the soft cord.

[0036] like Figure 3 and Figure 4 As shown, the front end of the housing 1 is fixedly connected to a magnetic attraction component 6, and the magnetic attraction component 6 includes a limit plate 61, the rear end of the limit plate 61 is fixedly connected to the front end of the housing 1, and the top of the limit plate 61 is fixedly connected to a magnetic attraction buckle 62;

[0037] The magnetic buckle 62 used in this scheme is a conventional device in the prior art, which is mainly composed of an upper cover, a tension spring, an inner sleeve, a steel ball and a bottom shell. When the steel needle is inserted, the steel ball is normally in a closed state due to the thrust of the tension spring. At this time, the steel ball is tightly buckled in the gap of the steel needle. When unlocking, you only need to place a strong magnet close to the anti-theft magnetic buckle. The strong magnet will easily absorb the steel ball and the iron ring pressed on the steel ball, the self-locking phenomenon disappears, the steel ball leaves the steel needle, and it is naturally unlocked.

[0039] The buzzer 7 and storage board 8 used in this solution are both conventional designs of the prior art. The buzzer 7 mainly serves as a warning and alarm. In this device, it is connected to the storage board 8 and the flip cover 2. When the flip cover 2 is maliciously damaged or the storage board 8 is damaged, the buzzer 7 will emit an alarm sound to warn the staff. The storage board 8 is mainly inlaid with RFID tags. The main function of the RFID tag is to identify and track objects. The RFID tag is usually composed of a chip and an antenna. The chip stores data, and the antenna is used to receive and send radio frequency signals.

[0040] The working principle of the utility model is as follows: when fixing clothing products, it is only necessary to place the magnetic buckle 62 on the surface of the clothing and pass the steel needle through the clothing and insert the steel needle into the inside of 62. When fixing other products, it is only necessary to pull the soft rope, at which time the soft rope will stretch, and then wrap the soft rope around the product, and then press the fixing block 2 56 to make the threading holes of the fixing block 1 55 and the fixing block 2 56 coincide, and pass the soft wire through the threading hole, and then release the fixing block 2 56. At this time, the fixing block 2 56 deviates from the threading hole of the fixing block 1 55 under the action of the spring 3 57, so as to achieve the purpose of clamping the soft rope; when the RFID tag needs to be replaced, it is only necessary to place a magnet on the top of the protective shell 1 41 to attract the spring 2 42, so that the sleeve 43 drives the wedge block 2 44 to move upward, so that the wedge block 2 44 is separated from the limit groove 346, thereby releasing the lock on the wedge block 1 342, and then sliding the slider 1 341.
