Embodiment Construction

[0018] The general idea of ​​the present invention is: a screw rod is arranged on the safety caliper connected with the ground wire, and the distance between a pair of clamp heads and the pressing force on the wire are adjusted by advancing and retreating of the screw rod. Introduce two kinds of embodiments below in conjunction with accompanying drawing.

[0019] The first embodiment: figure 1 figure 2 This paper introduces a kind of safety caliper connected with ground wire. Like the existing similar caliper, this caliper also has two opposite clamp heads 1, and the inside of the two clamp heads is an arc-shaped jaw 2, and the jaw 2 is clamped on the wire, that is, The connection of the ground wire can be completed. The difference is that this ground wire hook safety caliper is provided with a clamp base 3 for installing the clamp head, and a screw hole 4 is opened on the clamp base 3, and a screw rod 5 is installed in the screw hole 4, and one end of the screw rod 5 is co...

Abstract

The invention relates to an electrician instrument, in particular to safe calipers for hooking ground wires. The calipers comprise two opposite caliper heads (1). The inner sides of the two caliper heads (1) are each provided with an arc-shaped caliper opening (2). The calipers are characterized in that a caliper base (3) used for installing the caliper heads (1) is arranged on the safe calipers for hooking the ground wires (17); a screw hole (4) is formed in the caliper base (3); a threaded rod (5) is installed in the screw hole (4); one end of the threaded rod (5) is opposite to the caliper heads (1), and a rotating handle (6) is installed at the other end of the threaded rod (5). The safe calipers for hooking the ground wires have the beneficial effects that the opening and the closing angles of the caliper opening as well as the clamping force to the ground wires can be adjusted by rotating the threaded rod, and potential safety hazards of virtual connection, twisting, disengaging, wire damage and the like are eliminated; in addition, the structure is simple, the cost is low, and the calipers are expected to become a necessary tool in the industry.

Description

technical field [0001] The invention relates to an electrical appliance, that is, a ground wire hooked safety caliper. Background technique [0002] In the installation and maintenance process of electric facilities, in order to ensure the safety of operators, it is often necessary to install or remove the ground wire. The commonly used ground wire hooking method is to use the ground wire connecting pliers to hang the upper end of the ground wire on the wire. At present, the clamping force of the jaws of many ground wire connecting pliers is small, the connection with the wire is not firm, and the adjustment is inconvenient, there are safety hazards such as virtual connection, twisting or falling off, and it is easy to cause the wire to wear. Contents of the invention [0003] The purpose of the present invention is to provide a safety caliper with a ground wire that is easy to adjust the clamping force of the jaws, is firmly connected to the wire, has no safety hazards su...
