[0040] A fastening frame 33 is slidably disposed on the support plate 21, and the fastening frame 33 presses the sub-plates 3 disposed on the two support plates 21 to make the sub-plates 3 contact with the contact plate 24;

[0041] The turning frame 4 is hingedly arranged on the support plate 21 through a hinge shaft 42 arranged on one side, and the turning frame 4 is provided with abutment feet 41 corresponding to the plurality of elastic plates 25;

[0042] The gear rod 37 is fixedly mounted on the fastening frame 33 and meshes with the main gear 44 fixedly mounted on the hinge shaft 42 when the fastening frame 33 squeezes the sub-plate 3. The butt foot 41 flips over to push the elastic plate 25 to deform, and the elastic plate 25 deforms to cover the electrical plate 32 on the main plate 31 set on the mounting plate 2.

[0043] Specifically, the foot 41 is movably arranged in a plurality of movable grooves 22 provided on the support plate 21, and the elastic plates 25 are respectively fixedly installed on both sides of the notch of the movable groove 22, a torsion spring 43 is sleeved on the hinge shaft 42, and the two ends of the torsion spring 43 are respectively fixedly installed on the hinge shaft 42 and the support plate 21, and the torsion spring 43 drives the flip frame 4 to fit on the support plate 21 and maintain a vertical state. A slot 23 is provided on the support plate 21, and the pin 36 fixedly installed on the fastening frame 33 is inserted into the slot 23, and the gear rod 37 is fixedly installed on the pin 36. A plurality of electrical connection wires 9 corresponding to the contact plate 24 are arranged in the support plate 21, and a fitting block 91 electrically connected to the electrical connection wires 9 is fixedly mounted on the support plate 21, the elastic plate 25 is fixedly mounted on the fitting block 91, and the first end of the electrical connection wire 9 is fixedly mounted on the contact plate 24, and the contact plate 24 and the elastic plate 25 are electrically connected by using the electrical connection wire 9 and the fitting block 91. The cover 14 is assembled on the housing 1 to seal the main board 31 and the sub-board 3 in the housing 1.

[0044] Furthermore, by fixing the mounting plate 2 on the housing 1, and then placing the main plate 31 on the mounting plate 2, and the sub-plate 3 on the two support plates 21, and then inserting the pin 36 on the fastening frame 33 into the slot 23, and then utilizing the gear rod 37 on the pin 36 to engage with the main gear 44, the foot 41 on the flip frame 4 is flipped into the movable groove 22, and at this time the torsion spring 43 is deformed to store force. Then, the elastic plate 25 is pushed by the foot 41 to deform the elastic plate 25, and then the ends of the multiple elastic plates 25 are respectively moved along the side of the main board 31 to the main board 31 and cover, block and fix the main board 31. At the same time, the elastic plate 25 is deformed to cover and squeeze the electrical plate 32 on the main board 31. The fastening frame 33 is fixedly installed on the support plate 21 by bolts so that the fastening frame 33 squeezes the sub-board 3 and makes the sub-board 3 contact with the contact plate 24. Then, under the action of the electrical plate 32, the elastic plate 25, the bonding block 91, the electrical connection line 9 and the contact plate 24, the signal and current of the main board 31 are transmitted along the electrical plate 32, the elastic plate 25, the bonding block 91, the electrical connection line 9 and the contact plate 24 to the sub-board 3, or the signal on the sub-board 3 is transmitted to the main board 31, so as to realize the wire connection between the main board 31 and the sub-board 3. And the rapid fixation of the main board 31 and the sub-board 3 is realized. The electrical plate 32 , the elastic plate 25 , the bonding block 91 , the electrical connection line 9 and the contact plate 24 are respectively made of conductive metal materials.

[0045] Then, when the fastening frame 33 is removed from the support plate 21, the torsion spring 43 releases the stored force to drive the flip frame 4 to flip and reset, and at the same time, the foot 41 is separated from the elastic plate 25, and the elastic plate 25 is elastically reset to be separated from the main board 31, thereby releasing the fixation and position restriction of the main board 31. By disassembling the fastening frame 33, the main board 31 and the sub-board 3 can be quickly disassembled and fixed, and the wires between the main board 31 and the sub-board 3 can be connected.

[0046] In the above technical scheme, the main board component 31 is placed on the mounting plate 2, the sub-board component 3 is placed on the support plate 21 and fits against the contact plate 24, and then the fastening frame 33 is fixedly installed on the support plate 21 to squeeze the sub-board component 3, and the gear rod 37 on the fastening frame 33 and the main gear 44 are meshed to flip the flip frame 4, and then the flip frame 4 is used to push the elastic plate 25 to deform and cover the electrical plate 32 on the main board component 31, so as to realize the rapid limiting fixation of the main board component 31 and the sub-board component 3, and at the same time, the electrical connection between the contact plate 24 and the elastic plate 25 is used to make the main board component 31 and the sub-board component 3 electrically connected through the contact plate 24, the elastic plate 25 and the electrical plate 32, and the fastening frame 33 is disassembled to cooperate with the resetting of the elastic plate 25 to facilitate the rapid disassembly and replacement of the main board component 31 and the sub-board component 3.

[0047] As a further embodiment of the present invention, a fan 34 is fixedly mounted on the fastening frame 33, and when the abutting foot 41 pushes the elastic plate 25, the movable slot 22 on the supporting plate 21 is opened.

[0048] Specifically, in the default state, the torsion spring 43 drives the flip frame 4 to fit on the support plate 21 and maintain a vertical state. At this time, the flip frame 4 and the abutting foot 41 are used to cover the movable groove 22, and then when the pin 36 on the fastening frame 33 is inserted into the slot 23, the gear rod 37 on the pin 36 is meshed with the main gear 44, so that the abutting foot 41 on the flip frame 4 is flipped into the movable groove 22, and the torsion spring 43 is deformed and stored. At the same time, the flip frame 4 is flipped to open the movable groove 22, and the abutting foot 41 is flipped to swing in the movable groove 22, and then the abutting foot 41 is used to push the elastic plate 25 to deform the elastic plate 25, and then the ends of the multiple elastic plates 25 are respectively moved along the side of the main board component 31 to the main board component 31 and cover, cover and fix the main board component 31, and at the same time, the elastic plate 25 is deformed to cover and squeeze the electrical plate 32 on the main board component 31.

[0049] like Figure 6 and Fig.11 As shown, due to the flipping of the flip frame 4 and the abutment foot 41 to open the movable groove 22, while the fan 34 is used to blow air to dissipate the heat of the board surface of the sub-board 3, the air blown by the fan 34 is blown along the board surface of the flip frame 4 and the movable groove 22 to the main board component 31, and then the air blowing of the fan 34 and the air guiding effect of the flip frame 4 and the movable groove 22 can simultaneously achieve the effect of dissipating heat for the sub-board component 3 and the main board component 31.

[0050] As another embodiment provided by the present invention, when the fastening frame 33 squeezes the sub-panel 3, the multiple elastic sheets 35 fixedly mounted on the fastening frame 33 and the sub-panel 3 deform and store force when blocking and removing.

[0051] Specifically, a first end of the elastic sheet 35 is fixedly mounted on the fastening frame 33 , and a second end of the elastic sheet 35 is close to one side of the sub-board 3 . When the pin 36 on the fastening frame 33 is inserted into the slot 23 and the fastening frame 33 is close to the support plate 21, the second end of the elastic sheet 35 begins to fit on the sub-board 3 and blocks and disassembles with the sub-board 3 to deform and accumulate force. At this time, the gear rod 37 on the pin 36 is meshed with the main gear 44, so that the abutting foot 41 on the flip frame 4 is flipped into the movable groove 22, and the abutting foot 41 pushes the elastic plate 25 to deform the elastic plate 25, and then the ends of multiple elastic plates 25 are respectively moved along the side of the main board component 31 to the main board component 31 and cover, block and fix the main board component 31. At the same time, the elastic plate 25 is deformed to cover and squeeze the electrical board 32 on the main board component 31, and then under the flexible contact between the elastic sheet 35 and the sub-board component 3 and the elastic plate 25 and the main board component 31, while limiting and fixing the sub-board component 3 and the main board component 31, it can avoid problems such as damage to the circuit board caused by hard covering.

[0052] As another embodiment provided by the present invention, a locking member 45 is slidably provided on the fastening frame 33 for locking the fastening frame 33 and the support plate 21, and a push rod 47 is slidably provided on the outer wall of one side of the support plate 21 for pushing the locking member 45 to unlock it.

[0053] Specifically, Fig. 9 As shown, the push rod 47 is slidably set in a positioning groove opened on one side of the inner wall of the slot 23, the locking member 45 is slidably set in the pin 36 on the fastening frame 33, and a locking spring 46 is fixedly installed on the first end of the locking member 45, and the first end of the locking spring 46 is fixedly installed on the pin 36.

[0054] When the pin 36 on the fastening frame 33 is inserted into the slot 23, the second end of the elastic sheet 35 begins to fit on the sub-plate 3 and blocks the sub-plate 3 to deform and store force. At the same time, the gear rod 37 on the pin 36 meshes with the main gear 44, so that the foot 41 on the flip frame 4 is flipped into the movable groove 22, the torsion spring 43 deforms and stores force, and the foot 41 pushes the elastic plate 25 to deform the elastic plate 25, and then the ends of the multiple elastic plates 25 move along the side of the main plate 31 respectively. The main board 31 is pressed, covered and fixed to the main board 31, and the elastic plate 25 is deformed to press and squeeze the electrical plate 32 on the main board 31, and then the sub-board 3 and the contact plate 24 are closely fitted under the action of the elastic plate 25 and the elastic sheet 35, and the elastic plate 25 and the electrical plate 32 are closely fitted, so that the signal of the main board 31 can be transmitted to the sub-board 3 under the action of the electrical plate 32, the elastic plate 25, the fitting block 91, the electrical connection line 9 and the contact plate 24. At this time, the bottom end of the gear rod 37 is fitted to the bottom of the slot 23, and the second end of the locking member 45 is inserted into the positioning groove opened on one side of the inner wall of the slot 23 under the push of the locking spring 46, so that the pin 36 is locked on the support plate 21, so as to achieve the effect of fastening the fastening frame 33 to be quickly fixed and installed on the support plate 21.

[0055] When it is necessary to remove the fastening frame 33 on the support plate 21, the first ends of the push rods 47 on the support plate 21 are pressed respectively, so that the second ends of the push rods 47 push the locking member 45 out of the positioning groove. At this time, the elastic sheet 35, the elastic plate 25 and the torsion spring 43 are elastically reset to make the fastening frame 33 slide and move away from the support plate 21, thereby facilitating the removal of the fastening frame 33 from the support plate 21 to replace or maintain the sub-plate component 3 and the main plate component 31.

[0056] As another embodiment provided by the present invention, a locking block 6 is provided on the mounting plate 2, and a positioning block 5 is provided in the plug-in box 13 fixedly installed on the shell 1. When the first end of the locking block 6 is inserted in the plug-in box 13, the sliding block 8 on the locking block 6 is locked on the positioning block 5, and a lever 7 for sliding and unlocking the locking block 8 is hingedly provided on the locking block 6.

[0057] Specifically, a fixing spring 81 is fixedly mounted on the first end of the clamping block 8 , and the first end of the fixing spring 81 is fixedly mounted on the locking block 6 . A embedding groove 53 is provided on the positioning block 5 , and the first end of the shifting rod 7 is located on the clamping block 8 .

[0058] The locking block 6 is then disengaged from the embedding groove 53, and the mounting plate 2 is quickly removed from the housing 1 by moving the mounting plate 2 so that the first end of the locking block 6 is inserted into the insertion box 13. At this time, when the mounting plate 2 is attached to the insertion box 13, the fixing spring 81 pushes the card block 8 so that the second end of the card block 8 is engaged with the embedding groove 53, thereby locking the locking block 6 on the positioning block 5, and cooperating with the insertion box 13 to limit the locking block 6, so that the locking block 6 and the mounting plate 2 are quickly fixedly installed on the housing 1, and the second end of the lever 7 is pressed to make the first end of the lever 7 swing and move the card block 8, so that the card block 8 is disengaged from the embedding groove 53, and the mounting plate 2 is removed from the insertion box 13 by moving the mounting plate 2. Compared with the use of screws and other parts, the effect of quick disassembly and assembly of the mounting plate 2 can be achieved.

[0059] As the optimal embodiment provided by the present invention, cylindrical rods 15 are symmetrically arranged on the shell 1, and multiple conductive wires 16 fixedly installed on the cylindrical rods 15 are electrically connected to the corresponding elastic plates 25 respectively, and the first ends of the conductive wires 16 are located on the outside of the shell 1.

[0060] Specifically, the outer wall of the housing 1 is symmetrically provided with through slots 11, the mounting plate 2 is symmetrically provided with extension ends 26, and the second end of the electrical connection line 9 is located on the outer wall on one side of the extension end 26, the columnar rod 15 is provided with a side portion 17, and the second end of the conductive line 16 is located on the outer wall on one side of the side portion 17, and the second end of the conductive line 16 is in contact with the second end of the electrical connection line 9, so that when the cover 14 is used to close the main board component 31 and the sub-board component 3 in the housing 1, the first end of the conductive line 16 is exposed on the outer surface of the housing 1 through the through slot 11. At this time, an oscilloscope and a multimeter can be used to detect the electrical signal and current transmitted from the main board component 31 to the sub-board component 3, thereby eliminating the tediousness of opening the cover 14 to detect the main board component 31 and the sub-board component 3 in the housing 1, and thus facilitating subsequent repair and maintenance operations on the main board component 31. Especially for some electronic products of monitoring equipment, the mainboard used for monitoring inside will have problems such as inaccurate monitoring data after long-term use, and these problems sometimes cannot be fed back in the monitoring data, requiring workers to regularly check the internal parts and the output signals of the mainboard to ensure the stability of the parts. At the same time, compared with disassembling the cover 14 to check the main board component 31 and the sub-board component 3 in the shell 1, the second end of the bare conductive wire 16 can save the trouble of disassembly and assembly, and reduce the impact of vibration, static electricity, etc. on the circuit board caused by disassembly and assembly.

[0062] Specifically, the cylindrical rod 15 is rotated and arranged on the housing 1, so that when the main board component 31 needs to be detected, the cylindrical rod 15 is rotated to make the second end of the conductive wire 16 contact the second end of the electrical connection line 9, so that the second end of the conductive wire 16 can cooperate with the electrical connection line 9, the bonding block 91, the elastic plate 25 and the electrical plate 32 to receive information such as electrical signals transmitted from the main board component 31. When no detection is required, the cylindrical rod 15 is driven to rotate to make the side portion 17 away from the extension end 26, so that the circuit of the conductive wire 16 and the electrical connection line 9 is disconnected, and the first end of the conductive wire 16 is stored in the housing 1, thereby avoiding the first end of the conductive wire 16 being exposed for a long time and connected with the electrical connection line 9 when the main board component 31 signal is not detected, which affects the signal transmission of the main board component 31.

[0063] Furthermore, the cylindrical rod 15 may be rotated by a motor; or by manually driving a rack or a gear; or by any other method known to those skilled in the art for driving the cylindrical rod 15 to rotate.

[0064] As another embodiment provided by the present invention, a spiral guide groove 18 is provided on the outer wall of the columnar rod 15, and a guide rod 63 that moves synchronously is slidably arranged in the spiral guide grooves 18 of the two columnar rods 15. The two guide rods 63 slide to make the two columnar rods 15 flip synchronously and electrically connect the conductive wire 16 and the elastic plate 25.

[0065] Specifically, in order to make the conductive wires 16 on the two columnar rods 15 electrically connected to the elastic plate 25 on the support plate 21 at the same time, the two guide rods 63 are respectively slid in the spiral guide grooves 18 provided on the outer walls of the columnar rods 15, and then when the guide rods 63 slide, the two columnar rods 15 are simultaneously driven to flip, so that the conductive wires 16 on the columnar rods 15 are electrically connected to the elastic plate 25 on the support plate 21 at the same time.

[0066] The two guide rods 63 can slide simultaneously to make the two column rods 15 flip synchronously by fixing the two guide rods 63 together, and then pushing one of the guide rods 63 by an electric push rod to make the two guide rods 63 slide synchronously; or the two guide rods 63 can be fixed together, and then one of the guide rods 63 can be driven by a motor in conjunction with gears and racks; or other methods known to those skilled in the art to drive the two guide rods 63 to slide simultaneously are available.

[0067] As another embodiment further provided by the present invention, two guide rods 63 are symmetrically fixed on the locking block 6, and the locking block 6 slides on the mounting plate 2 and an extrusion spring 61 is arranged between the locking block 6 and the mounting plate 2. When the locking block 6 slides, the extrusion spring 61 is squeezed and deformed to store force and push the mounting plate 2 to fit onto the plug-in box 13.

[0068] Specifically, a support plate 27 is symmetrically fixedly installed in the mounting plate 2, such as Figure 4 and Figure 7 As shown, the first end of the extrusion spring 61 is fixedly mounted on the support plate 27, and the second end of the extrusion spring 61 is fixedly mounted on the locking block 6. The extrusion spring 61 pushes the locking block 6 in the default state and aligns one side of the locking block 6 with one side of the mounting plate 2, and the locking block 6 is slidably arranged in the guide groove 28 provided on the mounting plate 2 through the protrusion 62 arranged thereon. The positioning block 5 slides in the outer box 12 arranged on one side of the outer wall of the housing 1, and the outer box 12 and the plug box 13 are connected to each other.

[0069] The two columnar rods 15 are flipped so that one end notch of the spiral guide groove 18 on the two columnar rods 15 is located on the moving path of the two guide rods 63 on the locking block 6. Then, the positioning block 5 is fixed and the mounting plate 2 is moved so that the first end of the locking block 6 is inserted and set in the plug box 13. At the same time, the two guide rods 63 on the locking block 6 are close to the columnar rod 15 and when the mounting plate 2 is attached to the plug box 13, the two guide rods 63 are respectively moved into the spiral guide groove 18 on the two columnar rods 15, and the fixing spring 81 pushes the card block 8 so that the second end of the card block 8 is engaged in the embedding groove 53, thereby locking the locking block 6 on the positioning block 5. At this time, the mounting plate 2 is quickly installed on the housing 1, and the first end of the conductive wire 16 on the columnar rod 15 is received in the housing 1.

[0070] Furthermore, by placing the main board 31 on the mounting plate 2, and the sub-board 3 on the two support plates 21, and then by inserting the pins 36 on the fastening frame 33 into the slots 23, when the pins 36 on the fastening frame 33 are inserted into the slots 23, the second end of the elastic sheet 35 begins to fit on the sub-board 3 and blocks and disassembles with the sub-board 3 to deform and store force, and at the same time, the gear rod 37 on the pin 36 is meshed with the main gear 44, so that the foot 41 on the flip frame 4 is flipped into the movable groove 22, the torsion spring 43 is deformed and stores force, and the foot 41 pushes the elastic plate 25 so that the elastic plate 25 is deformed, and then the ends of the multiple elastic plates 25 are respectively moved along the side of the main board 31 to the main board 31 and cover, cover and fix the main board 31. At the same time, the elastic plates 25 are deformed to cover and squeeze the electrical plate 32 on the main board 31, and then the sub-board 3 and the contact plate 24 are closely fitted under the action of the elastic plates 25 and the elastic sheets 35, and the elastic plates 25 and the electrical plates 32 are closely fitted, so that under the action of the electrical plate 32, the elastic plates 25, the fitting block 91, the electrical connection line 9 and the contact plate 24, the signal of the main board 31 can be transmitted to the sub-board 3. At this time, the bottom end of the gear rod 37 is fitted to the bottom of the slot 23, and at the same time, the second end of the locking member 45 is inserted into the positioning groove opened on one side of the inner wall of the slot 23 under the push of the locking spring 46, so that the pin 36 is locked on the support plate 21, so as to achieve the effect of fastening the fastening frame 33 to be quickly fixed and installed on the support plate 21.

[0071] When the main board component 31 needs to be inspected, the positioning block 5 is pulled, and the positioning block 5 drives the locking block 6 to slide on the mounting plate 2, and the locking block 6 squeezes the squeezing spring 61 to deform and store force. At this time, the mounting plate 2 is attached to the plug box 13, so that the locking block 6 moves relative to the mounting plate 2. At this time, the two guide rods 63 on the locking block 6 slide in the spiral guide grooves 18 provided on the outer wall of the columnar rod 15, and then when the guide rods 63 slide, the two columnar rods 15 are driven to flip at the same time, so that the conductive wire 16 on the columnar rod 15 is electrically connected to the elastic plate 25 on the support plate 21. At the same time, due to the flipping of the columnar rod 15, the first end of the conductive wire 16 is exposed to the outside of the housing 1, so that the conductive wire 16 can be easily inspected, so as to detect whether the signal transmitted by the main board component 31 in the housing 1 is stable and correct without disassembling the housing 1.

[0072] As the optimal embodiment further provided by the present invention, the positioning block 5 slides in the outer box 12 arranged outside the shell 1, and the end of the clamping plate 51 fixedly installed on the positioning block 5 is movably arranged on the row of teeth 19 arranged on the inner wall of the outer box 12.

[0073] Specifically, Fig.12 As shown, the row of teeth 19 is arranged on the inner wall of the outer box 12, and the first end of the positioning block 5 is in contact with the inner wall of one side of the outer box 12 in the default state. An elastic push piece 52 is fixedly mounted on the positioning block 5, and the end of the elastic push piece 52 is in contact with the card plate 51, and the card plate 51 is pushed by the elastic push piece 52 so that the card plate 51 is in contact with the row of teeth 19.

[0074] Furthermore, by fixing the positioning block 5 and moving the mounting plate 2 so that the first end of the locking block 6 is plugged into the plug box 13, and at the same time, the two guide rods 63 on the locking block 6 are close to the cylindrical rod 15 and when the mounting plate 2 is attached to the plug box 13, the two guide rods 63 are respectively moved to the spiral guide grooves 18 on the two cylindrical rods 15, and at the same time, the fixing spring 81 pushes the card block 8 so that the second end of the card block 8 is engaged in the embedding groove 53, thereby locking the locking block 6 on the positioning block 5. At this time, the mounting plate 2 is quickly installed on the shell 1, and the first end of the conductive wire 16 on the cylindrical rod 15 is received in the shell 1.

[0075] Then, the main board 31 is placed on the mounting plate 2, and the sub-board 3 is placed on the two support plates 21, and then the pins 36 on the fastening frame 33 are inserted into the slots 23. When the pins 36 on the fastening frame 33 are inserted into the slots 23, the second end of the elastic sheet 35 begins to fit on the sub-board 3 and blocks and disassembles with the sub-board 3 to deform and store force. At the same time, the gear rod 37 on the pin 36 is meshed with the main gear 44, so that the foot 41 on the flip frame 4 is flipped into the movable groove 22, the torsion spring 43 is deformed and stores force, and the foot 41 pushes the elastic plate 25 so that the elastic plate 2 5 is deformed, and then the ends of the plurality of elastic plates 25 are respectively moved along the side of the main board 31 to the main board 31 and cover, block and fix the main board 31, and at the same time, the elastic plates 25 are deformed to cover and squeeze the electrical plate 32 on the main board 31, and then, under the action of the elastic plates 25 and the elastic sheets 35, the sub-board 3 and the contact plate 24 are closely fitted, and the elastic plates 25 and the electrical plate 32 are closely fitted, so that under the action of the electrical plate 32, the elastic plates 25, the fitting block 91, the electrical connection line 9 and the contact plate 24, the signal of the main board 31 can be transmitted to the sub-board 3. At this time, the bottom end of the gear rod 37 is fitted to the bottom of the slot 23, and at the same time, the second end of the locking member 45 is inserted into the positioning groove opened on one side of the inner wall of the slot 23 under the push of the locking spring 46, so that the pin 36 is locked on the support plate 21, so as to achieve the effect of fastening the fastening frame 33 to be quickly fixed and installed on the support plate 21.

[0076] When the main board 31 needs to be inspected, the second end of the positioning block 5 is pulled. At this time, the locking block 6 is locked on the positioning block 5. When the positioning block 5 is moved, the positioning block 5 drives the locking block 6 to slide on the mounting plate 2, and the locking block 6 squeezes the extrusion spring 61 to deform and store force. At this time, the mounting plate 2 is attached to the plug box 13, so that the locking block 6 moves relative to the mounting plate 2. At this time, the two guide rods 63 on the locking block 6 slide in the spiral guide grooves 18 provided on the outer wall of the columnar rod 15, and then when the guide rods 63 slide, the two columnar rods 15 are driven to flip at the same time, so that the conductive wire 16 on the columnar rod 15 is electrically connected to the elastic plate 25 on the support plate 21. At the same time, due to the flipping of the columnar rod 15, the first end of the conductive wire 16 is exposed to the outside of the housing 1.

[0077] When the positioning block 5 slides, the elastic push piece 52 pushes the card plate 51 so that the end of the card plate 51 switches between the multiple tooth openings on the row of teeth 19. Then, when the positioning block 5 stops moving, the elastic push piece 52 pushes the end of the card plate 51 to be inserted into one of the tooth openings of the row of teeth 19, and then cooperates with the elasticity of the extrusion spring 61 to keep the positioning block 5 and the locking block 6 stable, and the first end of the conductive wire 16 remains exposed to the outside of the shell 1.

[0078] After the detection is completed, the card plate 51 is pressed to make the end of the card plate 51 disengage from the tooth mouth of the row of teeth 19, and then released under the elastic reset of the extrusion spring 61 to drive the locking block 6 and the positioning block 5 to slide and reset. Due to the sliding reset of the locking block 6, the two guide rods 63 on the locking block 6 slide again in the spiral guide groove 18 opened on the outer wall of the cylindrical rod 15. At this time, the two cylindrical rods 15 flip over again. At this time, the second end of the conductive wire 16 and the electrical connection line 9 are disconnected from the circuit, and the first end of the conductive wire 16 is stored in the shell 1, thereby avoiding the first end of the conductive wire 16 being exposed for a long time and connected to the electrical connection line 9 when the signal detection of the main board component 31 is not performed, which affects the signal transmission of the main board component 31.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
