[0020] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0021] Example 1

[0022] This utility model provides a multi-functional operating handle, such as Figures 1 to 5 As shown, it includes an inner tube 1, one end of the outer surface of the inner tube 1 is threaded, a snap-fit ​​sleeve 2 is snapped onto one end of the inner tube 1, symmetrically installed receiving cylinders 3 are installed inside the snap-fit ​​sleeve 2, springs 4 are provided at the bottom of the two receiving cylinders 3, and top balls 5 are provided at the other end of the two springs 4, positioning pins 6 are fixedly installed on the outer surface of the snap-fit ​​sleeve 2 at both ends of the top balls 5, a fixing sleeve 7 is slidably installed on the outer surface of the inner tube 1, an outer tube 8 is welded onto one end of the fixing sleeve 7, and an end cap 9 is welded onto one end of the outer tube 8.

[0023] like Figure 4 and5 As shown, each of the two receiving cylinders 3 has a compression column 10 inside. One end of each of the two springs 4 is connected to the compression column 10. Support arms 11 are fixedly installed at opposite ends of the two compression columns 10. The same bidirectional screw 12 is connected through one end of the outer surface of the two support arms 11. Rotating seats 14 are rotatably installed at both ends of the outer surface of the bidirectional screw 12. The two rotating seats 14 are fixedly installed at one end of the snap-fit ​​sleeve 2. By rotating the bidirectional screw 12, the support arms 11 on the bidirectional screw 12 move to both ends of the bidirectional screw 12, and the distance between the two support arms 11 increases. At the same time, the compression column 10 connected to the support arm 11 compresses the spring 4, making the compression space of the spring 4 smaller. This allows the spring 4 to continuously provide a certain pressure, compensate for the loss of spring force caused by long-term compression, and ensure that the spring 4 always maintains sufficient compressive force on the top ball 5.

[0024] like Figure 4 and 5 As shown, both ends of the bidirectional screw 12 are fixedly equipped with rotating handles 13, which makes the bidirectional screw 12 easier to rotate and also serves to fix the bidirectional screw 12 to prevent it from falling off the rotating seat 14.

[0025] like Figure 2 and 3 As shown, observation holes 18 are symmetrically provided on one end of the outer surface of the outer tube 8 to observe whether the positioning pin 6 is engaged inside the fixed sleeve 7, so that the fixed sleeve and the inner tube 1 are installed stably.

[0026] like Figure 2 and 3 As shown, both the fixed sleeve 7 and the end cap 9 have grooves and locking holes on their outer surfaces. The grooves provide a sliding direction for the positioning pin 6. At this time, the top ball 5 is pressed against the inner wall of the fixed sleeve 7 and slides under the pressure. When the positioning pin 6 slides into the groove, the fixed sleeve 7 and the inner tube 1 are installed stably. At the same time, the top ball 5 slides to the locking hole position. At this time, the top ball 5 loses the pressure, so the spring 4 loses the pressure on the top ball 5, causing the top ball 5 to protrude from the outer surface of the positioning sleeve and be located inside the locking hole. This allows the top ball 5 to limit the fixed sleeve and prevent the fixed sleeve 7 from rotating and causing the groove to separate from the positioning pin 6.

[0027] like Figure 2 and 3 As shown, the inner tube 1 and the snap-fit ​​sleeve 2 are provided with fixing holes on their outer surfaces. Cylindrical pins are snapped into the fixing holes to ensure stable installation of the inner tube 1 and the snap-fit ​​sleeve 2.

[0028] Working principle: When the handle length needs to be extended, pull the outer tube 8, causing the fixed sleeve 7 to slide on the outer surface of the inner tube 1. The top ball 5 is squeezed by the inner wall of the fixed sleeve 7, causing the top ball 5 to squeeze the spring 4. When the fixed sleeve 7 slides to the top of the inner tube 1, the protruding positioning pin 6 prevents the fixed sleeve 7 from moving. Then, rotate the outer tube 8, which drives the fixed sleeve 7 to rotate and pull. When the inlet of the slide moves to the position of the positioning pin 6, the fixed sleeve 7 loses the obstruction of the positioning pin 6, allowing the positioning sleeve to continue sliding on the inner tube 1. At this time, the positioning pin 6 is located in the middle of the slide. Then, rotate the outer tube 8, so that the positioning pin 6 is located inside the slide, and the positioning pin 6 is located at the position of the observation hole 18. At the same time, the top ball 5 moves to the position of the locking hole. The top ball 5 loses the compression of the inner wall of the fixed sleeve, so the spring 4 loses the compression of the top ball 5. The spring 4 returns to its original expansion, pushing the spring 4 into the locking hole, so that the top ball 5... The fixed sleeve acts as a limit, preventing the fixed sleeve 7 from rotating and causing the slide groove to separate from the positioning pin 6. This ensures that the fixed sleeve is firmly fixed on the inner tube 1, allowing the inner tube 1 and outer tube 8 to be stretched, extending the handle length and making the handle a force-saving lever, making operation easier for the operator and improving work efficiency. When the spring 4 is compressed for too long, the spring 4 loses its elasticity. Rotating the handle 13 drives the double-acting screw 12 to rotate, causing the support arms 11 on the double-acting screw 12 to move to both ends of the double-acting screw 12. The distance between the two support arms 11 increases, and at the same time, the extrusion column 10 connected to the support arm 11 moves away from the bottom of the receiving cylinder 3, causing the extrusion column 10 to compress the spring 4. This reduces the compression space of the spring 4, thus continuously providing a certain pressure to the spring 4, compensating for the loss of spring 4 elasticity caused by prolonged compression, ensuring that the spring 4 always maintains sufficient extrusion force on the top ball 5, and extending the service life of the telescopic handle.

[0029] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
