The "in one embodiment" that appears in different places in this specification does not all refer to the same embodiment, nor is it an embodiment that is separate or selectively mutually exclusive with other embodiments.

[0029] Embodiment 1

[0030] Referring to Figure 1-Figure 3 , which is the first embodiment of the present utility model. This embodiment provides a clamping mechanism, including a grounding wire component 100, which includes a handle 101, a threaded rod 102 disposed at the top of the handle 101, a pressing plate 103 installed at the top of the threaded rod 102, and a joint 104 disposed above the handle 101; an upper clamping component 200, which includes an adjusting component 201 disposed on the joint 104, and a guiding component 202 installed on the adjusting component 201; and a side clamping component 300, which includes a gear component 301 disposed on the joint 104, a connecting component 302 disposed on the gear component 301, a linkage component 303 disposed on the connecting component 302, and a clamping component 304 disposed on the connecting component 302.

[0031] Specifically, the top of the handle 101 is fixedly connected to the threaded rod 102. The top of the threaded rod 102 is fixedly connected to a columnar pressing plate 103. The threaded rod 102 is threadedly connected to a joint 104 above it. The joint 104 is in a "C" shape. Among them, the pressing plate 103 slides within the joint 104. An adjusting component 201 is installed on the inner wall of the upper part of the joint 104 for clamping the circuit. A guiding component 202 is fixedly connected to the side of the adjusting component 201 for limiting the moving direction of the adjusting component 201 to prevent the adjusting component 201 from shifting during use. The gear component 301, the connecting component 302, the linkage component 303, and the clamping component 304 are used to clamp both sides of the circuit to prevent the circuit from falling off during use.

[0032] Furthermore, the adjusting component 201 includes a sliding hole 201a opened on the joint 104, a toothed rod 201b disposed within the sliding hole 201a, an arc-shaped plate 201c installed at one end of the toothed rod 201b, and a return spring 201d installed at the other end of the toothed rod 201b.

[0033] Specifically, a sliding hole 201a is opened above the joint 104, and a gear rod 201b is slidably connected in the sliding hole 201a. Tooth grooves are set on both sides of the gear rod 201b. An arc plate 201c is fixedly connected to the side surface of the downward end of the gear rod 201b, and a return spring 201d is fixedly connected between the side surface of the upward end of the gear rod 201b and the inner wall of the joint 104.

[0034] Furthermore, the guide assembly 202 includes a guide block 202 a installed on the side of the gear rod 201 b, and a guide groove 202 b installed on the inner wall of the joint 104 .

[0035] Specifically, a guide block 202a is fixedly connected to the side of the gear rod 201b, and a guide groove 202b is fixedly connected to the inner wall of the joint 104. The guide block 202a is slidably connected in the guide groove 202b to prevent the gear rod 201b from shifting in its moving direction.

[0036] Operation process: When in use, the grounding wire component 100 is hung on the line. When the line contacts the connector 104, the handle 101 falls downward due to gravity and is hung on the line. At this time, the arc plate 201c drives the gear rod 201b to move upward. The movement of the gear rod 201b compresses the return spring 201d. Since the guide block 202a on the side of the gear rod 201b slides in the guide groove 202b, the movement of the arc plate 201c will not be offset. When the handle 101 is lifted, the arc plate 201c is no longer supported by the line. At this time, the gear rod 201b moves downward due to its own gravity and the elastic force of the return spring 201d.

[0037] Example 2

[0038] Reference Figure 1-Figure 3 , which is the second embodiment of the utility model. This embodiment is different from the first embodiment in that: the gear assembly 301 includes a mounting groove 301a opened on the joint 104, a rotating shaft 301b installed in the mounting groove 301a, and a gear 301c arranged on the outer wall of the rotating shaft 301b; wherein the gear rod 201b is meshed with the gear 301c.

[0039] Specifically, a mounting groove 301a is formed on the inner wall above the joint 104, and a rotating shaft 301b is rotatably connected to both sides of the mounting groove 301a. A gear 301c is fixedly connected to the outer wall of the rotating shaft 301b, wherein the gear 301c is meshed with the gear rod 201b.

[0040] Furthermore, the connecting assembly 302 includes a connecting plate 302a disposed on the rotating shaft 301b, a connecting rod 302b disposed on the connecting plate 302a, and fixing plates 302c installed at both ends of the connecting rod 302b.

[0041] Specifically, the rotating shaft 301b is fixedly connected to one end of the connecting plate 302a, the connecting plate 302a is "concave", and the other end of the connecting plate 302a is rotatably connected to the connecting rod 302b, and both ends of the connecting rod 302b are fixedly connected to the fixing plate 302c.

[0042] Furthermore, the linkage assembly 303 includes a linkage shaft 303a installed in the installation groove 301a, a linkage plate 303b arranged on the outer wall of the linkage shaft 303a, and a linkage rod 303c arranged on the linkage plate 303b, and the linkage rod 303c can further support the fixed plate 302c to rotate.

[0043] Specifically, a linkage shaft 303a is fixedly connected in the installation groove 301a, and the linkage shaft 303a is arranged below the rotating shaft 301b. The outer wall of the linkage shaft 303a is fixedly connected to one end of the linkage plate 303b, and the other end of the linkage plate 303b is rotatably connected to a linkage rod 303c, which is fixedly connected between the fixed plates 302c.

[0044] Furthermore, the clamping assembly 304 includes a sliding hole 304 a opened on the joint 104 , a clamping block 304 b disposed in the sliding hole 304 a , and a rubber pad 304 c disposed on the clamping block 304 b .

[0045] Specifically, sliding holes 304a are opened on both sides of the joint 104, and a clamping block 304b is slidably connected in the sliding hole 304a. One end side of the clamping block 304b is fixedly connected between the fixed plates 302c, and a rubber pad 304c is set at the other end of the clamping block 304b. The rubber pad 304c is used to increase the friction when clamping the line.

[0046] The rest of the structure is the same as that of Example 1.

[0047] Operation process: during use, when the gear rod 201b moves upward, the gear rod 201b meshes with the gear 301c, driving the gear 301c to rotate, and the gear 301c drives the rotating shaft 301b to rotate, and the connecting plates 302a at both ends of the rotating shaft 301b rotate, and the connecting plates 302a drive the clamping blocks 304b under the fixed plates 302c to rotate, so that the clamping blocks 304b clamp the line to prevent the grounding wire component 100 from falling off when the connector 104 is hung on the line. When the handle 101 is lifted, the gear rod 201b moves downward, driving the gear 301c to rotate in the opposite direction, and the gear 301c drives the rotating shaft 301b to rotate in the opposite direction, and the connecting plate 302a rotates to the initial position. At this time, the clamping block 304b is away from the line, and the entire structure can quickly complete clamping and disengagement, which can effectively prevent the grounding wire component 100 from falling off and the troublesome phenomenon of the grounding wire component 100 being detached after being hung. The operation is simple, time-saving and labor-saving.

[0048] Example 3

[0049] Reference Figure 1-Figure 5 , which is the third embodiment of the utility model. Different from the above embodiments, this embodiment provides a non-contact ground wire head with electric induction alarm device, including the above-mentioned clamping mechanism, and also includes an alarm component 400, including an installation component 401 arranged on the connector 104, and an alarm component 402 arranged in the installation component 401.

[0050] Furthermore, the installation assembly 401 includes an installation box 401a disposed on the side of the connector 104, a first locking plate 401b installed on the side of the installation box 401a, a second locking plate 401c installed on the connector 104, and a screw 401d disposed on the second locking plate 401c.

[0051] Specifically, the installation box 401a is arranged on the side of the connector 104, and a first locking plate 401b is fixedly connected to the side of the installation box 401a, and a second locking plate 401c is fixedly connected to the side of the connector 104, wherein the first locking plate 401b and the second locking plate 401c correspond in position, and a screw 401d is arranged between the first locking plate 401b and the second locking plate 401c, and the screw 401d fixes the first locking plate 401b and the second locking plate 401c.

[0052] Furthermore, the alarm component 402 includes a voltage stabilizing circuit 402a disposed in the installation box 401a, a single-chip microcomputer 402b disposed in the installation box 401a, an audible and visual alarm circuit 402c disposed in the installation box 401a, a button circuit 402d disposed in the installation box 401a, and an electric field sensor 402e disposed in the installation box 401a.

[0053] Specifically, the voltage stabilizing circuit 402a, the single-chip computer 402b, the sound and light alarm circuit 402c, the key circuit 402d and the electric field sensor 402e are all arranged in the installation box 401a. The voltage stabilizing circuit 402a is composed of a 9V lithium battery, a linear voltage stabilizing chip and an input and output filter capacitor. The lithium battery provides energy for the entire circuit. The key circuit 402d is composed of a resistor, a key switch and a capacitor. The resistor mainly plays a current limiting role. When the key switch is pressed, the pin of the single-chip computer 402b is grounded through the resistor to prevent the pin of the single-chip computer 402b from being damaged due to excessive grounding current. The capacitor is used for hardware debouncing of the key. When the key is pressed, multiple jitters may occur due to the mechanical switch. The capacitor is used to filter out the jitter signal to make the level signal read by the single-chip computer 402b interface more stable. The main function of the key circuit 402d is to detect whether the alarm device is working properly. 02e is used to detect the electric field strength of charged equipment. The electric field strength generated by different voltage levels is different. After the output of the electric field sensor 402e is connected to the voltage follower, it is connected to the ADC sampling port of the microcontroller 402b to read the electric field strength signal. Under normal circumstances, the resistor can set the output pin of the microcontroller 402b to a low level to prevent the field effect tube from being misconnected and causing a false alarm. The resistance value is generally greater than 10kΩ. The resistor is used to limit the output current of the microcontroller 402b pin to prevent the output from being directly grounded when the field effect tube is damaged, burning the output pin of the microcontroller 402b. It can also be used to limit the current flowing through the light-emitting diode to prevent the light-emitting diode from being burned by excessive current. By changing the resistance value of the resistor, the brightness of the light-emitting diode can also be adjusted. The resistor is also used to limit the current flowing through the buzzer to prevent the buzzer from being burned by excessive current. By changing the resistance value of the resistor, the volume of the buzzer can also be adjusted.

[0054] The rest of the structure is the same as that of Example 2.

[0055] Operation process: When in use, when the key switch in the key circuit 402d is pressed, the pin of the single-chip microcomputer 402b recognizes a low-level signal, and the pin of the single-chip microcomputer 402b outputs a PWM signal of a specific time and a specific frequency, which can test whether the alarm circuit is working normally. When the electric field strength output by the electric field sensor 402e is greater than the electric field strength value set by the single-chip microcomputer 402b, the single-chip microcomputer 402b outputs a PWM signal of a specific frequency to drive the field effect tube to turn on. At this time, the light-emitting diode flashes at the set frequency, and the buzzer beeps at the same frequency to realize an audible and visual alarm and serve as a reminder. The entire structure can effectively prevent operators from mistakenly hanging the connecting wire on live equipment. The structure does not affect the normal installation of the connecting wire, is simple to install, and has no effect on the induced voltage alarm device. It only emits an audible and visual alarm when it senses that the electrical equipment is live.

Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
