The stroke positioning device 14 is composed of a rod 141, a spring 142 and a positioning ball 143, and the positioning ball 143 always moves close to the inner wall of the assembling hole 114. When the positioning ball 143 moves to the position opposite to the position of the position hole 111 at the limit retraction position, the positioning ball 143 moves to the position hole 111 at the limit retraction position under the pressing action of the spring 142, so that the fixed base 11 and the inner movable frame 12 are easily fixed, as shown in fig. 4. When the positioning ball 143 moves to the position opposite to the positioning hole 113 of the extending limit position, the positioning ball 143 moves to the positioning hole 113 of the extending limit position under the pressing action of the spring 142, so that the fixing base 11 and the inner movable frame 12 are simply fixed, please refer to fig. 3.
The bottom of the fastening screw 15 is contacted with the inner movable frame 12, so that the fixed seat 11 and the inner movable frame 12 are effectively fixed through friction.
The insulating plastic seat 16 is inserted into the socket 2, the push button 23 is pushed to press the locking surface 281 of the abutment block 28 against the insulating plastic seat 16, and the socket 2 and the insulating plastic seat 16 are effectively fixed by friction.
The inserting part C is connected with the threaded sleeve part B through threads, and when the inserting part C is damaged, the inserting part C can be unscrewed for replacement, so that the service life of the movable connector is prolonged.
The above description is provided for the purpose of describing the present invention in more detail, and it should not be construed that the present invention is limited to the description, and it will be apparent to those skilled in the art that various modifications and substitutions can be made without departing from the spirit of the present invention.
