Self-locking type electric test clamp

Abstract

The invention provides a self-locking type electric test clamp, which can be used for preventing the clamp from loosening and falling due to accidental collision in the testing process to influence an experiment, and even cause dangers. The self-locking type electric test clamp comprises an upper clamping sheet, a lower clamping sheet, a torque spring, a shaft and a sliding block, wherein tail ends of the upper clamping sheet and the lower clamping sheet are drilled with round holes; the shaft passes through the round holes and is pivoted at two ends; the torque spring is sleeved on the shaft, and the upper clamping sheet and the lower clamping sheet have an opening tendency under the elastic action of the torque spring; two sides of the lower clamping sheet are provided with slotted holes, and the sliding block can slide on the slotted holes; and the two clamping sheets are closed when the sliding block slides in a direction away from the shaft and are opened when the sliding block moves backwards. The clamp can be opened to a certain angle and is fixed when not being used for clamping an electrode; and the clamp has a self-locking function after being used for clamping the electrode, and is not easy to loosen by external force as long as not moving the sliding block.

Description

Technical field [0001] The invention relates to an electrical test clamp with a self-locking structure, which can be opened at an angle and fixed when the electrode is not clamped, and is not easy to loosen when the electrode is clamped. Background technique [0002] Traditional electrical test clamps generally use the force generated by the spring deformation to clamp the electrode. Some clamps have relatively small clamping force, which makes it easy to open the chuck, but because the force is relatively small after clamping the electrode, when the clamp is accidentally touched during operation, the chuck is easy to loosen and fall, affecting the progress of the experiment or even causing danger ; Some clamps have a relatively large clamping force, which requires a relatively large force to open the chuck. Even in this way, it is difficult to avoid accidental collision with the clamp. Summary of the invention [0003] In view of the shortcomings of the above-mentioned clamps, t...

Problems solved by technology

Some clamps have a relatively small clamping force, which makes it easy to open the clamp. However, due to the relatively small force after clamping the electrode, when the clamp is accidentally touched during operation, the clamp is easy to loosen and fall, which will affect the progress of the experiment and even cause danger. ; Some clips have a relatively large clamping force, and a relatively large force is required to open the clip. Even so, it is difficult to avoid accidental collisions and the clip falling off.
