The voltage detector head is fixedly connected to the top of the connecting rod. A protective plate is fixedly sleeved on the outer wall of the mounting block. Multiple support blocks are fixedly connected to the outer wall of the connecting rod. The support blocks are connected to the top of the protective plate via a telescopic rod.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figure 1-2 A telescopic voltage detector designed to prevent accidental activation includes a mounting block 1, a connecting rod 2, and a voltage detector head 3. A handle 11 is fixedly connected to the bottom of the mounting block 1 for easy operation of the voltage detector. The mounting block 1 has a cavity in which a screw 4 is rotatably inserted to drive the connecting rod 2 to move up and down. A worm gear 5 is fixedly sleeved on the screw 4 to drive the screw 4 to rotate. A worm 6 that meshes with the worm gear 5 is rotatably inserted in the cavity to drive the worm gear 5 to rotate. A knob 7 is fixedly connected to one end of the worm 6 to drive the worm 6 to rotate. A locking groove is provided on the outer wall of the mounting block 1, and a locking mechanism corresponding to the knob 7 is fixedly connected in the locking groove to lock and fix the knob 7. In this embodiment, the locking mechanism includes a fixed rod 12, an L-shaped locking rod 13 is slidably sleeved on the fixed rod 12, and a plurality of locking grooves corresponding to the L-shaped locking rod 13 are arranged around the knob 7 for locking and fixing the knob 7. A spring 14 is sleeved on the fixed rod 12, and the two ends of the spring 14 are fixedly connected to the L-shaped locking rod 13 and the inner wall of the locking groove respectively, providing a certain elastic support for the L-shaped locking rod 13. In this embodiment, the top of the screw 4 penetrates the inner wall of the cavity and extends upward. The connecting rod 2 is provided with a threaded groove corresponding to the screw 4. One end of the screw 4 located in the threaded groove is fixedly connected to a limiting block 16 to prevent the screw 4 from falling out of the threaded groove. The voltage tester 3 is fixedly connected to the top of the connecting rod 2. In this embodiment, a protective plate 8 is fixedly sleeved on the outer wall of the mounting block 1 to prevent accidental contact. An insulating pad 15 is fixedly adhered to the bottom of the protective plate 8 to enhance its insulation protection capability. Multiple support blocks 9 are fixedly connected to the outer wall of the connecting rod 2. The support blocks 9 are connected to the top of the protective plate 8 through a telescopic rod 10 to prevent the connecting rod 2 from shaking.

[0016] In this embodiment, rotating the knob 7 can drive the worm gear 6 to rotate, and the meshing action between the worm gear 6 and the worm wheel 5 can drive the screw 4 to rotate, thereby driving the voltage detector 3 to move up and down through the connecting rod 2 to adjust the position of the voltage detector 3. Then, the knob 7 is locked and fixed by the locking mechanism. At the same time, the telescopic rod 10 can prevent the connecting rod 2 from shaking, and the protective plate 8 can play a role in preventing accidental contact.
