wherein, a tooth surface matched with the rack outside the clamping plate 219 is arranged on the side wall of the mounting chamber 110 contacted with the clamping plate 219.

The positioning clamp 211 is arranged in the installation chamber 110 and is formed by connecting two clamping plates 219 through a rotating pin 212, the joint can rotate freely, a clamping spring 214 is further arranged between the two clamping plates 219, so that the two clamping plates 219 are tightly attached to the side wall of the installation chamber 110, and the racks on the clamping plates 219 are matched with the rack surface on the contact side wall of the installation chamber 110, so that the clamping plates 219 can only move downwards in one direction and cannot move upwards to form a self-locking device. So that the movable assembly 210 can be fixed on the sidewall of the installation chamber 110 and can slide down on the sidewall of the installation chamber 110. The movable plate 213 of the movable assembly 210 and the fixed plate 220 cooperate to form a mounting chamber. When the electric wire clamping device is used, only the electric wire is placed in the installation chamber 110 firstly, then the movable assembly 210 is pressed downwards to enable the movable plate 213 and the fixed plate 220 to tightly clamp the electric wire, so that the electric wire is ensured to be in close contact, the installation is convenient and fast, and the use of operating tools such as a screwdriver is omitted.

Referring to fig. 5, the clamping plate 219 includes a clamping portion 232 and a holding portion 231, the clamping portion 232 is spaced apart from the holding portion 231 in a normal direction, the rack is disposed at the clamping portion 232, and the rotation pin 218 is disposed at a transition between the clamping portion 232 and the holding portion 231.

When the air switch needs to be overhauled and removed, the clamping spring 214 can be compressed by pressing the handheld part 231, then the rack on the clamping plate 219 can be separated from the tooth surface of the mounting cavity 110, so that the movable component 210 can move upwards, the movable plate 213 is far away from the fixing plate 220, the electric wire mounted between the movable plate 213 and the fixing plate 220 can be taken out, the electric wire can be conveniently replaced and overhauled, and the effect of repeated use of the utility model is achieved.

Two sides of the fixed plate 220 are provided with long plates 221 in the vertical direction, and the long plates 221 are provided with through grooves 222; the two ends of the movable plate 213 are provided with protruding plates 217, the protruding plates 217 pass through the through slots 222, the lower ends of the protruding plates 217 are provided with springs 216, and the upper ends and the lower ends of the springs 216 are respectively in contact with the protruding plates 217 and the bottom of the installation chamber 110.

When the air switch needs to be overhauled or the wire needs to be replaced, by tightening the positioning clamp 210, when the rack on the clamping plate 219 is separated from the tooth surface on the mounting chamber 110, the positioning clamp 219 can be simply ejected out of the mounting chamber by the upward acting force of the spring 216 on the positioning clamp 219, so that the wire is more convenient to overhaul or replace.

The protruding plate 217 and the portion of the bottom of the installation chamber 110 contacting the spring 216 are provided with fixing posts 215, and the spring 216 is sleeved on the fixing posts 215.

The spring 216 is sleeved on the fixed column 215, so that the spring 216 can be installed conveniently, the spring 216 only needs to be sleeved on the fixed column 215, and when the air switch is wired or overhauled, when the positioning clamp 219 moves, the fixed column 215 limits the movement of the spring 216 in other directions, so that the spring 216 can only move up and down stably.

A bead 223 is provided on the lower surface of the movable plate 213 and/or the upper surface of the fixed plate 215. The cross-sectional shape of the bead may be square, triangular, circular, etc.

The upper clamping plate and the lower clamping plate of the traditional wiring chamber are planes, so that the electric wire is easily pulled out after being installed, and the wiring is not firm. The pressing strips 223 are arranged to enable the wires to be pressed more tightly between the movable plate 213 and the fixed plate 215, so that the tight contact between the wires and the fixed plate 215 is ensured, and the stable transmission of power is ensured.

The retaining clip 211 and the rotation pin 212 are both of an insulating material.

The positioning clamp 211 is made of insulating materials, such as plastics, insulating ceramics and the like, so that the safety of workers during operation is guaranteed, and electric shock is prevented.

When the wire clamping device is used, firstly, an electric wire to be installed is placed into an installation cavity formed by the fixed plate 220 and the movable plate 213, the positioning clamp 211 moves downwards by back pressing, the rack of the clamping plate 219 is in contact with the tooth surface on the installation cavity due to the action of the clamping spring 214, the clamping plate 219 can only move downwards due to the fact that the tooth surface is inclined downwards to form a self-locking structure, and after the electric wire is clamped by the fixed plate 220 and the movable plate 213, installation is completed. When the air switch needs to be overhauled and the wire needs to be detached, only the hand-held part 231 on the positioning clamp 211 needs to be squeezed by fingers, so that the clamping part 232 is retracted inwards, the rack on the clamping plate 219 is separated from the tooth surface on the mounting chamber 110, and then the positioning clamp 211 is upwards popped out of the mounting chamber 110 through the action of the spring 216, so that the fixed plate 220 is separated from the movable plate 213, and the wire is conveniently taken out.

The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structures or equivalent flow changes made by the contents of the specification and the drawings, or directly or indirectly applied to other related technical fields, are included in the same way in the protection scope of the present invention.
