Description
Technical Field
[0001] The utility model belongs to the technical field of electric test pens, and more specifically relates to an electric test pen with a clamping function. Background Art
[0002] A voltage tester, also known as a test pencil or electrician's pencil, is a common tool used by electricians to determine whether an object is charged. Its operating principle is that a potential difference forms between the charged object, the voltage tester, the human body, and the earth. This creates an electric field, which causes the neon tube in the voltage tester to glow.
[0003] Existing testers typically only measure electrical voltage. Whether contact or inductive, they require additional tools to grip components. Because testers can't directly grip components, users may need to frequently switch tools during electrical repairs or installations. This wastes time, disrupts workflows, and reduces efficiency. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide an electrical tester with a clamping function, which has the advantages of portability and applicability.
[0005] To achieve the above objectives, the present invention provides the following technical solutions:
[0006] A tester with a clamping function, comprising a tester body and a sleeve portion, wherein the sleeve portion is transparent and has a circular hole extending from the top to the bottom. The tester body is located in the circular hole. The sleeve portion has a plurality of rectangular grooves at the bottom, and mounting bars are slidably connected to the rectangular grooves.
[0007] The mounting bar is provided with a plurality of mounting rods extending from the end face of one side away from the tester body, and a clamping part is rotatably connected between the mounting rods. A compression spring is provided between the mounting bar and the clamping part, and the two ends of the compression spring are fixedly connected to the mounting bar and the clamping part respectively. The left and right end faces of the sleeve part are provided with threaded holes communicating with the rectangular groove, and the threaded holes are provided with matching adjustment bolts.
[0008] The advantages of this solution include at least one: the tester can be used to clamp components or wires. When clamping is required, the user simply presses open the clamping portion on the mounting bar. The compression spring ensures that the other end of the clamping portion firmly secures the mounting bar, allowing the clamping portion to clamp the component or wire to the mounting bar. The mounting bar can also be adjusted to the required clamping length. Once adjusted, simply tighten the adjustment bolt. This adapts to tools of varying lengths, improving flexibility and convenience. This eliminates the need for a separate clamping tool, enhancing the convenience of the tester. It not only secures the test tool, preventing it from slipping or moving during use, preventing it from accidentally falling off, and ensuring operator safety, thereby improving test accuracy and safety, but also ensures the stability and accuracy of the test tool and enhances flexibility and convenience.
[0009] The utility model is further configured as follows: the test pencil body is threadedly connected to the round hole on the socket portion.
[0010] The advantage of this solution is at least that when the mounting bar is adjusted to the maximum limit and still cannot meet the required clamping length, the tester body can be rotated for thread adjustment, allowing the tester body to move forward and backward. The dual adjustment structure greatly improves convenience.
[0011] The utility model is further configured as follows: a slide groove is provided in the rectangular groove, and a sliding block adapted to the slide groove is provided on one side of the mounting bar away from the bottom of the sleeve portion.
[0012] The advantages of this solution include at least one: the provision of the slide groove and slider not only limits the range of motion of the mounting bar, preventing it from moving beyond the specified position and thus avoiding damage, but also serves as a guide, directing the relative movement between the rectangular groove and the mounting bar, maintaining a smooth trajectory and preventing deviation or jamming. This improves precision and stability.
[0013] The utility model is further configured as follows: a rubber block is provided at one end of the adjusting bolt that contacts the mounting strip.
[0014] The advantage of this solution is at least that: by providing the rubber block, the friction between the mounting strip and the adjusting bolt can be enhanced, the mounting strip and the adjusting bolt can be protected, and the stability of the connection and the convenience of installation can be improved.
[0015] The utility model is further configured as follows: both left and right end surfaces of the sleeve portion are provided with limiting circular grooves for limiting the adjusting bolts.
[0016] The advantage of this solution is at least that: by providing a limiting circular groove, the adjusting bolt is adjusted into the limiting circular groove when tightening the adjusting bolt, which not only avoids damage to the exterior of both sides of the sleeve part due to frequent adjustment of the adjusting bolt, but also prevents the adjusting bolt from shaking, thereby improving the fixing effect.
[0017] The utility model is further configured such that: an anti-slip strip is provided on the end surface area of one side where the installation strip and the clamping portion are close to each other.
[0018] The advantage of this solution is that the provision of the anti-slip strip significantly increases the friction between the clamped component and the mounting strip and clamping portion, thereby preventing the component from slipping or falling off during the clamping process. The anti-slip strip not only prevents slippage but also effectively protects the clamped component.
[0019] The utility model is further configured as follows: an adjustment portion is provided on the top of the electrical test pencil body.
[0020] The advantage of this solution is at least that: by providing the adjustment portion, when the test pencil body needs to be thread-adjusted, the test pencil body can be adjusted conveniently by holding the adjustment portion, thereby improving the adjustment efficiency.
[0021] In summary, the present invention has at least the following advantages:
[0022] 1. The provision of the chute and slider not only limits the range of motion of the mounting strip, preventing it from moving beyond the specified position and thus avoiding damage, but also serves as a guide, directing the relative movement between the rectangular slot and the mounting strip, maintaining a smooth trajectory and avoiding deviation or jamming. This improves precision and stability. The provision of rubber blocks enhances the friction between the mounting strip and the adjusting bolt, protecting both, and contributing to improved connection stability and installation convenience.
[0023] 2. By providing a limiting circular groove, the adjusting bolt is adjusted into the limiting circular groove when tightening. This not only avoids damage to the exterior of the sleeve on both sides due to frequent adjustment of the adjusting bolt, but also prevents the adjusting bolt from shaking, thereby improving the fixing effect. By providing an anti-slip strip, the friction between the clamped component and the mounting strip and clamping part can be significantly increased, thereby preventing the component from slipping or falling off during the clamping process. The anti-slip strip not only prevents slippage, but also effectively protects the clamped component. By providing an adjustment part, when the tester body needs to be threaded, it is convenient to adjust the tester body by holding the adjustment part, thereby improving adjustment efficiency.

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.
[0032] A test pencil with a clamping function, such as Figure 1 Shown and Figure 2 As shown, it includes a test pen body 1 and a sleeve part 2. The sleeve part 2 is transparent and has a circular hole 3 from the top to the bottom (refer to Figure 3 ), the test pencil body 1 is located in the circular hole 3, and the bottom of the sleeve 2 is provided with a plurality of rectangular grooves 4 (reference Figure 5 ), a mounting bar 5 is slidably connected in the rectangular groove 4, and a plurality of mounting rods 6 are extended from the end surface of the mounting bar 5 away from the test pencil body 1. A clamping part 7 is rotatably connected between the mounting rods 6. A compression spring 8 is provided between the mounting bar 5 and the clamping part 7. The two ends of the compression spring 8 are fixedly connected to the mounting bar 5 and the clamping part 7 respectively. The left and right end surfaces of the sleeve 2 are provided with threaded holes 9 communicating with the rectangular groove 4 (reference Figure 3), a matching adjustment bolt 10 is located in the threaded hole 9. When clamping is required, the user simply presses open the clamping portion 7 on the mounting bar 5. The compression spring 8 ensures that the other end of the clamping portion 7 firmly secures the mounting bar 5. The clamping portion 7 can clamp the component or wire to the mounting bar 5. The mounting bar 5 can also be adjusted to the required clamping length. After adjustment, tighten the adjustment bolt 10. This adapts to tools of varying lengths, improving flexibility and convenience. This eliminates the need for a separate clamping tool, enhancing the convenience of the tester. It not only secures the test tool, preventing it from slipping or moving during use, preventing it from accidentally falling off, and ensuring operator safety, thereby improving the accuracy and safety of the test. It also ensures the stability and accuracy of the test tool and enhances its flexibility and convenience.
[0033] like Figure 3 As shown, the tester body 1 is threadedly connected to the circular hole 3 on the socket 2. If the mounting bar 5 is adjusted to its maximum position and still cannot meet the required clamping length, the tester body 1 can be rotated to adjust the thread, allowing the tester body 1 to move forward and backward. This dual-adjustment structure greatly improves convenience.
[0034] like Figure 3 As shown, a slide groove 11 is provided in the rectangular groove 4 (refer to Figure 5 A slider 12, which mates with the chute 11, is provided on the side of the mounting bar 5 away from the bottom of the sleeve 2. The chute 11 and slider 12 not only limit the range of motion of the mounting bar 5, preventing it from moving beyond the specified position and thus avoiding damage, but also serve as a guide, directing the relative movement between the rectangular slot 4 and the mounting bar 5, maintaining a smooth trajectory and preventing deviation or jamming. This improves precision and stability.
[0035] like Figure 3 As shown, a rubber block 13 is provided at one end of the adjusting bolt 10 in contact with the mounting bar 5. The rubber block 13 can enhance the friction between the mounting bar 5 and the adjusting bolt 10, protect the mounting bar 5 and the adjusting bolt 10, and help improve the stability of the connection and the convenience of installation.
[0036] like Figure 3 As shown, both left and right end surfaces of the sleeve portion 2 are provided with limiting circular grooves 14 for restraining the adjusting bolt 10. By providing the limiting circular grooves 14, when tightening the adjusting bolt 10, the adjusting bolt 10 is adjusted into the limiting circular grooves 14, which not only avoids damage to the exterior of the sleeve portion 2 due to frequent adjustment of the adjusting bolt 10, but also prevents the adjusting bolt 10 from shaking, thereby improving the fixing effect.
[0037] like Figure 2As shown, anti-slip strips 15 are provided on the end surfaces of the mounting bar 5 and the clamping portion 7 where they approach each other. The provision of anti-slip strips 15 significantly increases the friction between the clamped component and the mounting bar 5 and clamping portion 7, thereby preventing the component from slipping or falling off during the clamping process. Anti-slip strips 15 not only prevent slippage but also effectively protect the clamped component.
[0038] like Figure 3 As shown, an adjustment portion 16 is provided on the top of the test pencil body 1. By providing the adjustment portion 16, when the test pencil body 1 needs to be thread-adjusted, the test pencil body 1 can be adjusted conveniently by holding the adjustment portion 16, thereby improving the adjustment efficiency.
[0039] The working process and beneficial effects of the present invention are as follows: The electric tester of the present invention can be used to clamp components or wires. When a situation requires clamping, the user only needs to press open the clamping portion 7 on the mounting bar 5. Because the principle of the compression spring 8 can make the other end of the clamping portion 7 firmly fix the mounting bar 5, the clamping portion 7 can clamp the clamped component or wire to the mounting bar 5. The mounting bar 5 can also be adjusted according to the clamping length required by the actual situation. After the adjustment is completed, tighten the adjusting bolt 10. It can adapt to tools of different lengths and improve the flexibility and convenience of use. The operator no longer needs to use a separate clamping tool, which improves the convenience of the electric tester. It can not only be used to fix the detection tool, avoid the tool from slipping or moving during use, prevent the tool from accidentally falling off, and ensure the safety of the operator, thereby improving the accuracy and safety of the detection. It also ensures the stability and accuracy of the detection tool and improves the flexibility and convenience of use.
[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the design concept of the present invention should be included in the scope of protection of the present invention.
