[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0023] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the present invention should be understood by people with ordinary skills in the field to which the present invention belongs. The words "first", "second" and similar words used in the present invention do not indicate any order, quantity or importance, but are only used to distinguish different components.

"Connect" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0024] like Figure 1-Figure 5 As shown, a connector for a telescopic rod includes: a connector 3, the connector 3 includes a left connector shell 301 and a right connector shell 307 fixedly installed on one side of the left connector shell 301, a slider 304 is slidably connected inside the combined cavity of the left connector shell 301 and the right connector shell 307, one end of the slider 304 is fixedly connected to a wire rope fixing piece 303, one end of the slider 304 is fixedly connected to a tension spring 302, and the tension spring 302 is sleeved on the outside of the wire rope fixing piece 303, the other end of the tension spring 302 is fixedly installed at the bottom end of the cavity formed by the left connector shell 301 and the right connector shell 307, a wire rope through hole 309 is opened at one end of the left connector shell 301 away from the tension spring 302, a wire rope 300 is fixedly connected to the wire rope fixing piece 303, the wire rope 300 passes through the interior of the tension spring 302 and penetrates the wire rope through hole 309.

[0025] In this way, by pulling the wire rope 300, the slider 304 slides in the internal cavity of the connecting head 3, and a force is applied to the clamping head 4 at one end of the slider 304, so that the clamping head 4 can perform various actions such as clamping or rotation, and the slider 304 can achieve more precise reciprocating motion under the rebound force of the tension spring 302, thereby accurately controlling the clamping degree of the clamping head to adapt to the clamping needs of objects of different sizes and shapes. The built-in wire rope is not easy to be entangled or hooked with surrounding objects, which reduces accidental interference during operation and improves work efficiency.

[0026] As an optional implementation, Figure 1-Figure 5 As shown, the steel wire rope 300 passes through the telescopic rod body 2 and is wound along the fixed wheel 310 and installed on the spring wheel 311. The lower end of the spring wheel 311 is fixedly installed with a gear 316 and is rotatably installed on the telescopic rod handle 1;

[0027] A plate fastener 314 is slidably connected to the telescopic rod handle 1, one end of the plate fastener 314 is snap-connected to a plate fastener tension spring 315, the other end of the plate fastener tension spring 315 is fixedly installed on the telescopic rod handle 1, and the other end of the plate fastener 314 is rotatably connected to a toothed buckle 312;

[0028] A toothed buckle tension spring 313 is fixedly connected to one side of the toothed buckle 312 , and the other end of the toothed buckle tension spring 313 is fixedly mounted on the telescopic rod handle 1 . The end of the toothed buckle 312 away from the plate fastener 314 corresponds to the gear 316 .

[0029] In this way, the rebound force of the tension spring 302 is smaller than the internal rotational force of the spring wheel 311. Without applying force to the plate fastener 314, the spring inside the spring wheel 311 keeps 300 in a taut state, applies downward force to the plate fastener 314, and pushes the gear 316 to rotate through the tooth buckle 312. Then the spring wheel 311 drives the wire rope 300 to pull the slider 304 to slide. By utilizing the mechanical principle of the gear 316, a smaller tension can be converted into a larger force to move heavy objects, which greatly saves manpower, can more accurately control the moving speed and position of the heavy objects, and avoids loss of control due to excessive force.

[0030] As an optional implementation, Figure 2 As shown, a pressing groove fixing groove 308 is opened on one side of the right connector shell 307, and a pressing clip 306 is fixedly installed inside the pressing groove fixing groove 308. A spring piece 305 is set on one side of the pressing clip 306, and the spring piece 305 is fixedly installed inside the right connector shell 307.

[0031] In this way, the spring sheet 305 acts on the pressing fastener 306, so that the pressing fastener 306 has a certain resilience. The spring sheet 305 can make the pressing fastener 306 recover quickly, so that it is fastened in time, preventing personal injury caused by the clamping falling off due to untimely fastening.

[0032] As an optional implementation, Figure 1 As shown, the telescopic rod body 2 is fixedly mounted on the telescopic rod handle 1, and a connector 3 is fixedly mounted on one end of the telescopic rod body 2 away from the telescopic rod handle 1;

[0033] One end of the connector 3 away from the telescopic rod body 2 is snap-connected with a clamping head 4 .

[0034] In this way, by adjusting the length of the telescopic rod 2, it can adapt to a variety of different work tasks and objects. Whether clamping small items or larger objects, it can be achieved by adjusting the length of the telescopic rod 2.

[0035] In this embodiment, if Figure 1-Figure 5 As shown, by adjusting the length of the telescopic rod body 2, it can adapt to a variety of different work tasks and objects. Whether it is clamping small items or larger objects, it can be achieved by adjusting the length of the telescopic rod body 2. Inside the telescopic rod handle 1, the rebound force of the tension spring 302 is smaller than the internal rotation force of the spring wheel 311. When no force is applied to the plate fastener 314, the spring inside the spring wheel 311 keeps 300 in a taut state, applies a downward force to the plate fastener 314, and pushes the gear 316 to rotate through the tooth buckle 312, and then the spring wheel 311 drives the wire rope 300 to pull the slider 304 to slide. By using the mechanical principle of the gear 316, a smaller pulling force can be converted into a larger The force is used to move heavy objects, which greatly saves manpower and can more accurately control the moving speed and position of the heavy objects, avoiding loss of control caused by excessive force. The slider 304 slides in the internal cavity of the connecting head 3 by pulling the wire rope 300, and a force is applied to the clamping head 4 at one end of the slider 304, so that the clamping head 4 can perform various actions such as clamping or rotation, and the slider 304 can achieve more precise reciprocating motion under the rebound force of the tension spring 302, so as to accurately control the clamping degree of the clamping head to adapt to the clamping needs of objects of different sizes and shapes. The built-in wire rope is not easy to be entangled or hooked with surrounding objects, which reduces accidental interference during operation and improves work efficiency.
