Abstract

The invention discloses a special tool for metering. The special tool comprises a base, a seal fixing slot, a connecting rod and a pressing block, wherein one side of the base extends outwards to forman extended sleeve; the connecting rod is horizontally arranged on the base in a sliding mode after passing through a spring, the extended sleeve and a fixed bolt fixedly arranged at the outer side end of the extended sleeve; one end of the connecting rod extends to the outer side of the extended sleeve; the other end of the connecting rod is connected to the pressing block; and the seal fixing slot is arranged on the base in a mode of being matched with the position of the pressing block. A seal is placed in the seal fixing slot, and a handle is pulled backwards for enabling a high-strengthspring which is arranged on the connecting rod in a through mode to extrude, so that instantaneous locking of the seal is realized by driving the pressing block to apply force on the seal through theconnecting rod under elastic force of the spring after the handle is released. The special tool for metering solves the problems that an existing seal pressing way easily hurts fingers, is low in working efficiency, and the like.

Description

technical field [0001] The invention relates to the field of electric mechanical tools, in particular to a special measuring tool. Background technique [0002] In the normal work of the electric power metering major, it is necessary to seal the electric meter and the electric meter box with the seal for electric meter verification after the meter is calibrated and the meter is installed and accepted. The seal generally includes seal screws and seal buckles. Usually, the operator will use needle-nose pliers to press the buckle to lock when conditions permit. However, when using needle-nose pliers to lock, the efficiency will decrease due to incorrect tools; and large Part of the time, the operator directly uses fingers to press to lock. When the workload is huge, long-term and frequent pressing will cause certain damage to the staff's fingers. In addition, tools such as Phillips screwdrivers are sometimes needed during the verification process, and operators need to carry m...
