[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] In the description of the present invention, it should be understood that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", "clockwise", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0028] Reference Figure 1-5 The video surveillance pole grounding network device provided by the embodiment of the utility model includes a clamp body 1 and a handle 2 connected to the clamp body 1, the handle 2 is provided with a display screen 3, and the handle 2 is provided with a protective mechanism, and the position of the protective mechanism is arranged corresponding to the position of the display screen 3; the protective mechanism includes a sliding sleeve 4 fixed to the handle 2, and a protective baffle 5 is slidably arranged inside the sliding sleeve 4, and the protective baffle 5 includes a first section 501 and a second section 502 that are slidably connected to each other.

[0029] Specifically, the pliers body 1 includes two arc-shaped parts, and the two arc-shaped parts are hinged on the handle 2, and a through hole for the wire to pass through is constructed between the two. The display screen 3 is also arranged on the handle 2. When measuring the resistance of the wire, the two parts of the pliers body 1 are opened, and then the connecting wire is placed in the through hole through the open end of the pliers body 1, and then the two parts of the pliers body 1 are closed. The resistance value of the wire can be displayed on the display screen 3 (for specific measurement prevention, please refer to the patent document with the authorization announcement number CN220399543U). In order to prevent the display screen 3 from being damaged, a protective baffle 5 is slidably arranged on the handle 2. This is a prior art and will not be repeated. One of the core innovations of the utility model First, a sliding sleeve 4 and a retractable protective baffle 5 are provided on the handle 2, that is, the protective baffle 5 includes a first section 501 and a second section 502 which are slidably connected to each other, and a sliding cavity is provided inside the sliding sleeve 4 and the first section 501, the first section 501 is slidably connected to the sliding cavity on the sliding sleeve 4, and the second section 502 is slidably connected to the sliding cavity on the first section 501. When the protective baffle 5 is unfolded, it can block the display screen 3, thereby preventing the display screen 3 from being damaged. When the protective baffle 5 is retracted, it can be away from the display screen 3, thereby facilitating reading of the value on the display screen 3. The advantage of such a configuration is that the space occupied by the protective mechanism can be reduced by retracting the protective baffle 5.

[0030] Furthermore, a force-applying plate 6 is disposed on the second section 502. Specifically, the force-applying plate 6 is a square plate body, which is vertically arranged on the second section 502, and can provide a force-applying point for the second section 502, so as to facilitate the expansion and contraction of the protective baffle 5.

[0031] Furthermore, a blocking block 7 is provided on the handle 2 , and an elastic sheet 8 is provided on the blocking block 7 . The elastic sheet 8 is located on the movement stroke of the force applying plate 6 . Specifically, there are two blocking blocks 7 and two elastic sheets 8, and the elastic sheet 8 is preferably arc-shaped and fixed to the surface of the blocking block 7 close to the force-applying plate 6. The purpose of such a setting is that when the protective baffle 5 is unfolded, the force-applying plate 6 is pulled, and the two sides of the force-applying plate 6 abut against the arc-shaped surfaces of the elastic sheet 8. When the force applied to the force-applying plate 6 is greater than the force required for the elastic sheet 8 to deform, the elastic sheet 8 is deformed to achieve avoidance. When the second section 502 abuts against the side of the blocking block 7, the second section 502 stops, so that the protective baffle 5 can be flexibly fixed in the expanded state by the elastic sheet 8. When the protective baffle 5 needs to be retracted, the force-applying plate 6 is pushed in the reverse direction, so that the force-applying plate 6 abuts against the elastic sheet 8. At this time, the elastic sheet 8 is deformed to achieve avoidance, so that the force-applying plate 6 moves away from the elastic sheet 8. Continuing to push the force-applying plate 6 can switch the protective baffle 5 from the expanded state to the retracted state.

[0032] Furthermore, a driving button 9 is rotatably provided on the handle 2. Specifically, the cross section of the driving button 9 is preferably fan-shaped, and it is rotatably provided on the side of the handle 2, and a torsion spring is provided between the driving button 9 and the pliers body 1, and the elastic force of the torsion spring makes the driving button 9 have a tendency to rotate in a direction away from the handle 2, and a transmission member (not shown in the figure) is provided between the driving button 9 and the pliers body 1, and the transmission member is used to convert the rotational force of the driving button 9 into a force for opening the pliers body 1, which is a prior art and will not be described in detail. When the pliers body 1 needs to be opened, the driving button 9 is pressed, and the pliers body 1 can be opened through the transmission member, and the torsion spring is charged, and then the wire is placed in the through hole, and the driving button 9 is released, and under the action of the elastic force of the torsion spring, the driving button 9 can be driven to reset, and the pliers body 1 can be driven to close.

[0033] Furthermore, the driving button 9 is provided with an anti-skid portion 10. Specifically, the anti-skid portion 10 is a plurality of evenly arranged protruding structures, and is made of a material with a large dynamic friction coefficient such as rubber, which can provide friction between the hand and the driving button 9 for easy force application.

[0034] Furthermore, a limiting portion 11 is provided on the driving button 9. The limiting portion 11 is provided on the arc surface of the driving button 9 and protrudes from the arc surface of the driving button 9. When the torsion spring drives the driving button 9 to reset, the limiting portion 11 abuts against the handle 2 and the side wall of the internal space, thereby preventing the driving button 9 from rotating excessively.

[0035] Furthermore, the driving button 9 is provided with an anti-accidental touch component; the anti-accidental touch component includes a locking groove 12 opened on the driving button 9, a mounting groove 13 is opened inside the handle 2, a locking block 14 is slidably arranged inside the mounting groove 13, and the locking block 14 has a first position for engaging with the locking groove 12 and a second position for being away from the locking groove 12. Specifically, as Figure 4 As shown, the locking groove 12 is opened on the arc-shaped surface of the driving button 9 and is arranged horizontally. The locking block 14 is L-shaped, which includes a horizontal section and a vertical section. The size of the end of the horizontal section of the locking block 14 is adapted to the size of the locking groove 12. The purpose of such a setting is that when the device is not in use, the locking block 14 is provided with a horizontal leftward force through the existing reciprocating drive component components such as the electric push rod, so that the end of the horizontal section of the locking block 14 is inserted into the locking groove 12, so that the driving button 9 cannot be rotated, so as to fix the position of the driving button 9 to prevent accidental touch. When the device is in use, the locking block 14 is provided with a horizontal rightward force, so that the horizontal section of the locking block 14 is separated from the locking groove 12, thereby releasing its locking effect on the driving button 9 to achieve the purpose of preventing accidental touch.

[0036] As an alternative to the above-mentioned electric push rod driving the locking block 14 to move horizontally, preferably, an abutment rod 15 is fixedly connected to the first section 501, and the locking block 14 is located on the movement stroke of the abutment rod 15. A spring 16 is provided between the locking block 14 and the mounting groove 13. Specifically, the abutment rod 15 is fixedly connected to the lower surface of the first section 501 and is located at one end close to the sliding sleeve 4. The end of the abutment rod 15 is arc-shaped, and a wedge-shaped surface is provided on the vertical section of the locking block 14. The wedge-shaped surface is located on the movement stroke of the arc surface of the abutment rod 15. One end of the spring 16 is fixedly connected to the vertical section, and the other end is fixedly connected to the side wall of the mounting groove 13. The effect of such a setting is that when the protective baffle 5 is converted from the expanded state to the retracted state, it will drive the first section 501 to slide toward the inside of the sliding sleeve 4, thereby synchronously driving the abutment rod 15 to slide in the direction of the locking block 14. When the abutment rod 15 is in an arc shape, a wedge-shaped surface is provided on the vertical section of the locking block 14. The wedge-shaped surface is located on the movement stroke of the arc surface of the abutment rod 15. One end of the spring 16 is fixedly connected to the vertical section, and the other end is fixedly connected to the side wall of the mounting groove 13. The effect of such a setting is that when the protective baffle 5 is converted from the expanded state to the retracted state, it will drive the first section 501 to slide toward the inside of the sliding sleeve 4, thereby synchronously driving the abutment rod 15 to slide in the direction of the locking block 14. When the arc surface of the connecting rod 15 abuts against the wedge surface of the locking block 14, it will drive the locking block 14 to slide to the right and accumulate force on the spring 16, so that the end of the horizontal section of the locking block 14 is pulled out from the locking groove 12 to achieve the effect of passive unlocking. When the device is used up, the protective baffle 5 is converted from the retracted state to the expanded state, thereby driving the abutment rod 15 to move in the opposite direction. When the abutment rod 15 is away from the vertical section of the locking block 14, the elastic force of the spring 16 is released, so that the end of the horizontal section of the locking block 14 is inserted into the locking groove 12 to lock the driving button 9 again.

[0037] Furthermore, the abutment rod 15 is provided with a first friction portion 17, and the locking block 14 is provided with a second friction portion 18. The first friction portion 17 and the second friction portion 18 are preferably made of a material with a large dynamic friction coefficient such as rubber, and the second friction portion 18 is located on the movement stroke of the first friction portion 17, and a damping structure (not shown in the figure) is respectively provided between the first section 501 and the inner wall of the sliding sleeve 4 and between the first section 501 and the second section 502. The effect of such a setting is that when the protective baffle 5 is in a retracted state, the positions of the first section 501 and the second section 502 can be flexibly fixed under the action of the damping structure, and when the abutment rod 15 abuts against the locking block 14 so that the horizontal section of the locking block 14 is moved from the locking state to the locking state, the first section 501 and the second section 502 can be flexibly fixed. After being pulled out from the groove 12, the abutment rod 15 continues to slide, so that the first friction portion 17 moves to the side of the second friction portion 18, and under the elastic force of the spring 16, the first friction portion 17 is tightly attached to the second friction portion 18, so as to increase the resistance when the first friction portion 17 and the second friction portion 18 slide relative to each other, so as to avoid sliding of the abutment rod 15 and the first section 501 as much as possible, so as to improve the stability of the first section 501 when it is inside the sliding sleeve 4. When it is necessary to convert the protective baffle 5 from the retracted state to the expanded state again, it is only necessary to provide the force applying plate 6 with a larger reverse force.

[0038] The handle 2 is provided with a hook 19. The specific hook 19 is L-shaped and is arranged on the surface of the handle 2 away from the display screen 3. Through the hook 19, the device can be placed on a structure such as a frame to facilitate the storage of the device.

[0039] The above only describes some exemplary embodiments of the present invention by way of illustration. 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.
