[0002] In order to improve the efficiency of power detection and maintenance, most power workers have begun to be equipped with handheld power detection devices. The detection device held in the hand will form a conductive structure between the detected equipment and the human body, which will inevitably pose a safety hazard. In addition, when a person is electrocuted, his hand will naturally clench into a fist, thereby firmly holding the handheld power detection device, thereby reducing the user's survival rate after electric shock. This requires the use of a handheld multifunctional live detection device, so the existing handheld multifunctional live detection device has been continuously innovated and developed. Therefore, it can be seen that the current handheld multifunctional live detection device basically meets people's needs, but there are still some problems.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1 、 Figure 3 and Figure 4 A handheld multifunctional live detection device includes a handheld detector 1, a display screen 2 is provided on the top of the front of the handheld detector 1, a button 3 is provided on the bottom of the front of the handheld detector 1, and slide grooves 4 are provided on both sides of the handheld detector 1;

[0026] The trigger mechanism includes a slider 5, the surface of which is slidably connected to the inner wall of the slide groove 4, a gripping plate 6 is provided on one side of the slider 5, spring plates 7 are provided on both sides of the gripping plate 6, a connecting plate 8 is provided on one side of the spring plate 7, an L-shaped clip 9 is provided on one side of the connecting plate 8, clip grooves 10 are provided on both sides of the middle of the slide groove 4, a return spring 11 is provided in the middle of the slide groove 4, and the bottom end of the return spring 11 is overlapped with the inner wall of the slider 5.

[0027] When using a handheld multifunctional live detection device, first hold both sides of the gripping plate 6, and then use the detection head 14 on the top of the handheld detector 1 to detect the electrical appliance to be detected. If an unexpected situation occurs during the detection process and the user is electrocuted, the human body will produce a physiological reaction due to the electric shock, causing muscle spasms and paralysis, which will cause the hand to naturally clench into a fist. At this time, the clenched palm will squeeze the spring sheets 7 on both sides of the gripping plate 6. The squeezing of the spring sheets 7 will drive the two sets of connecting plates 8 to move relative to each other. The movement of the connecting plate 8 drives the L-shaped card strip 9 to move toward the inner walls on both sides of the handheld detector 1. After the L-shaped card strip 9 is removed from the card slot 10, the connection between the gripping plate 6 and the handheld detector 1 is released. At this time, the elastic force of the reset spring 11 pushes the slide Block 5, since the acting force is mutual, and the slider 5 and the holding plate 6 are both held in the user's hand, the elastic force of the reset spring 11 pushes the handheld tester 1 out of the holding plate 6, thereby disconnecting the connection between the user's hand and the handheld tester 1. When the handheld tester 1 needs to be installed in the holding plate 6, first align the slide grooves 4 on both sides of the handheld tester 1 with the slider 5, slide the slider 5 into the slide groove 4, and then hold the spring sheet 7 firmly to push the L-shaped clip 9 into the holding plate 6, and then slide the holding plate 6 into the middle of the surface of the handheld tester 1, release the spring sheet 7, and the reset of the spring sheet 7 drives the connecting plate 8 and the L-shaped clip 9 to reset, so that the L-shaped clip 9 is reset and then snapped into the slot 10, and then the holding plate 6 is installed on the surface of the handheld tester 1.

[0028] See also Figures 1 to 3A storage slot 12 is provided on one side of the top of the handheld detector 1, and a detection line 13 is provided on the other side of the top of the handheld detector 1. A detection head 14 is provided at one end of the detection line 13. The surface of the detection head 14 is provided with an anti-slip plate, and the detection head 14 is inserted into the inner wall of the storage slot 12. The appearance of the detection line 13 is a coiled spring with a certain elasticity. The diameter of the detection head 14 is consistent with the diameter of the inner wall of the storage slot 12.

[0029] When using a handheld multifunctional live detection device, first hold the detection head 14 and pull it out from the storage slot 12, and then detect the electrical appliance through the detection head 14 and the detection line 13. The elastic detection line 13 can be stretched and can be reeled up after use by its own elastic force.

[0030] See also Figure 2 、 Figure 4 and Figure 5 , movable grooves 15 are opened on both sides of the top of the hand-held detector 1, and the inner wall of the movable groove 15 is slidably connected with a pin 16. A slot 17 is opened on one side of the top of the slider 5, and the inner wall of the holding plate 6 is movably connected to the surface of the hand-held detector 1. A telescopic rod 18 is provided in the middle of the slide groove 4, and the bottom end of the telescopic rod 18 is provided at the bottom end of the reset spring 11. Limiting plates 19 are provided on both sides of the inner wall of the holding plate 6, and one side of the connecting plate 8 is overlapped with one side of the limiting plate 19.

[0031] Before using the handheld tester 1, first push the latch 16 so that the latch 16 slides in the movable groove 15 and is stored in the handheld tester 1, and then use the handheld tester 1. After using the handheld tester 1, push the latch 16 to slide the latch 16 into the slot 17, thereby fixing the handheld tester 1 and the slider 5. The telescopic rod 18 can limit the telescopic direction of the reset spring 11 to prevent the reset spring 11 from bending. The limit plates 19 on both sides of the holding plate 6 can prevent excessive squeezing of the spring sheet 7, which causes the connecting plate 8 to be squeezed into the inner side of the holding plate 6, causing the connecting plate 8 to affect the normal pop-up of the handheld tester 1.

[0032] Working principle: when using a handheld multifunctional live detection device, before using the handheld detector 1, first push the pin 16 to release the fixation between the handheld detector 1 and the holding plate 6, then hold the detection head 14 and pull the detection head 14 out of the storage slot 12, and detect the electrical appliance through the detection head 14 and the detection line 13. When an unexpected situation occurs during the detection process and the user is electrocuted, the user's hand will naturally clench into a fist and squeeze the spring sheet 7, thereby driving the L-shaped clip 9 to move. At this time, the slider 5 is pushed by the elastic force of the reset spring 11. Since the action force is mutual, and the slider 5 and the holding plate 6 are both held in the user's hand, the elastic force of the reset spring 11 pushes the handheld detector 1 out of the holding plate 6, thereby disconnecting the connection between the user's hand and the handheld detector 1.

[0033] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
