Description

Technical Field

[0001] This invention relates to a quick connector for telescopic pole tools, and more particularly, to a quick connector for telescopic poles. Background Technology

[0002] Existing tools such as fruit pickers, fruit shears, and snake catchers require the use of telescopic poles. Since these tools are all fixedly installed at the front end of the telescopic pole and need to work in conjunction with the internal levers to complete their respective operations, each tool requires a separate telescopic pole, resulting in waste.

[0003] Currently, there is a lack of a quick-connect structure that allows tools such as fruit pickers, fruit shears, and snake catchers to be quickly mounted on telescopic poles. Different usage scenarios only require different quick-connects, saving costs and providing a quick and convenient way to replace telescopic pole quick-connects. Summary of the Invention

[0004] The purpose of this invention is to provide a quick connector for telescopic poles, which solves the problem in the prior art of lacking a quick connector structure that allows tools such as fruit pickers, fruit shears, and snake catchers to be quickly installed on telescopic poles. Different usage scenarios only require different quick connectors, saving costs and providing a quick and convenient way to replace telescopic pole quick connectors.

[0005] This invention is achieved through the following technical solution:

[0006] A quick connector for a telescopic rod includes a telescopic tube with a connecting rod II inside. A connector tube is sleeved on the telescopic tube, and a connecting rod I is inside the connector tube. A push button is mounted on the connector tube via a pin I. An elastic element is provided between the push button and the connector tube. The push button has a pin and a pressing plate. The telescopic tube has a pin hole and an elongated hole. A limiting head is provided on the connecting rod I. A card structure is provided on the connecting rod II. The card in the card structure cooperates with the limiting head. The connector tube has a tool mounting hole, and the pin cooperates with the pin hole. The pressing plate slides in the elongated hole.

[0007] Furthermore, the limiting head is provided with a limiting groove, and the card structure also includes a torsion spring. The torsion spring and the card are mounted on the fixed seat through a pin II. The pin II passes through the fixed seat, the card, the torsion spring and the connecting rod II in sequence. One end of the torsion spring abuts against the lower part of the card, and the other end abuts against the connecting rod II. The fixed seat is slidably installed in the telescopic tube. The front end of the card is provided with a limiting ring, and the limiting groove cooperates with the limiting ring.

[0008] Furthermore, the limiting head is provided with a guide hole, and the front end of the connecting rod II is provided with a guide head.

[0009] Furthermore, the front end of the limiting head is provided with a conical surface, which can tilt the card upwards.

[0010] Furthermore, the elastic element is a spring.

[0011] Furthermore, the connector tube is provided with a support ring, and the connecting rod I is slidably installed in the circular hole on the support ring.

[0012] Furthermore, the connector tube around the button is provided with a protective wall, and a pin I passes through the protective wall to fix the button.

[0013] Furthermore, the pin is provided with an inclined surface.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. Tools such as fruit pickers, fruit shears, and snake catchers are installed on the connector tube through tool mounting holes and connecting rod I. The original telescopic rod pull rod structure is improved, and a card structure and limit head are added to achieve quick docking.

[0016] 2. Different usage scenarios only require changing the quick connector with different tools installed, saving costs and making replacement quick and convenient.

[0017] 3. The guide head and guide hole can play a role in smooth guidance when installing quick couplings. Attached Figure Description

[0027] The present invention will now be further described in conjunction with the accompanying drawings.

[0028] like Figure 1-2 As shown in Embodiment 1, a quick connector for a telescopic rod includes a telescopic tube 4, a connecting rod II 11 inside the telescopic tube 4, a connector tube 2 sleeved on the telescopic tube 4, a connecting rod I 1 inside the connector tube 2, a push button 3 mounted on the connector tube 2 via a pin I, an elastic element 13 between the push button 3 and the connector tube 2, a pin 6 and a pressing piece 7 on the push button 3, a pin hole 20 and an elongated hole 21 on the telescopic tube 4, a limiting head 12 on the connecting rod I 1, a card structure on the connecting rod II 11, a card 8 in the card structure cooperating with the limiting head 12, a tool mounting hole 22 on the connector tube 2, the pin 6 cooperating with the pin hole 20, the pressing piece 7 sliding within the elongated hole 21, and the tool mounting hole 22 being a threaded hole.

[0029] like Figure 3-5 As shown in Embodiment 2, a quick connector for a telescopic rod includes a limiting groove 15 on the limiting head 12. The card structure also includes a torsion spring 10. The torsion spring 10 and the card 8 are mounted on a fixed base 9 via a pin II. The pin II passes through the fixed base 9, the card 8, the torsion spring 10, and the connecting rod II 11 in sequence. One end of the torsion spring 10 abuts against the lower part of the card 8, and the other end abuts against the connecting rod II 11. The fixed base 9 is slidably mounted inside the telescopic tube 4. A limiting ring 19 is provided at the front end of the card 8, and the limiting groove 15 cooperates with the limiting ring 19. The limiting head 12 is provided with a guide hole 17, and the front end of the connecting rod II 11 is provided with a guide head. 14. The guide head 14 can provide stable guidance during the insertion of the guide hole 17; the front end of the limiting head 12 is provided with a tapered surface 16, which can tilt the card 8 upward; the elastic element 13 is a spring; the connector tube 2 is provided with a support ring 5, and the connecting rod I1 is slidably installed in the round hole on the support ring 5; the connector tube 2 around the button 3 is provided with a protective wall, and a pin I passes through the protective wall, which fixes the button 3; the pin 6 is provided with an inclined surface 18, which facilitates pushing the pin 6 into the pin hole 20, and the rest is the same as in embodiment 1.

[0030] When using Figure 6As shown, one arm of the fruit-picking shears is bolted to the tool mounting hole 22, and the other arm is connected to the connecting rod I1 by bolts and nuts.

[0031] When using Figure 7 As shown, one arm of the snake catcher is bolted to the tool mounting hole 22, and the other arm is connected to the connecting rod I1 by bolts and nuts.

[0032] When using Figure 8 As shown, the fruit picker is installed on the tool mounting hole 22 by bolts, and the connecting rod I1 is threadedly connected to the fruit picker's fruit picker gripping connecting plate.

[0033] The fruit-picking shears, snake catcher, and fruit picker are all existing devices. Pulling the operating handle will cause the lever inside the telescopic rod to move the connecting rod II11 and the fixed base 9 backward, which in turn will move the connecting rod I1 backward, thus realizing the operation of the fruit-picking shears, snake catcher, and fruit picker.

[0034] After the aforementioned fruit-picking shears, snake catchers, or fruit pickers are installed, align the telescopic tube 4 and the connector tube 2, and push the connector tube 2. The pressing plate 7 slides within the elongated hole 21, and the conical surface 16 contacts the card 8. Under the action of the torsion spring 10, the card 8 is lifted, causing the limiting groove 15 to engage with the limiting ring 19. Simultaneously, under the action of the spring and the inclined surface 18, the pin 6 is smoothly lifted when it contacts the telescopic tube 4, and then the pin 6 enters the pin hole 20, completing the installation of the quick connector. When it is necessary to disassemble the quick connector, simply press the pressing button 3. At this time, the pressing plate 7 presses down on the card 8, the limiting groove 15 disengages from the limiting ring 19, and the pin 6 disengages from the pin hole 20. Then, pull out the connector tube 2 to complete the quick disassembly. The support ring 5 makes the movement of the connecting rod I1 smoother.
