Detailed Implementation

[0019] The following will describe specific embodiments and appendices. Figure 1-11 The technical solutions in the embodiments of this utility model are clearly and completely described below. Obviously, the described embodiments are only some preferred embodiments of this utility model, and not all embodiments. Those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0020] This utility model provides a telescopic rod internal traction variable distance structure (such as...) Figure 1As shown), it includes a pull rope 1, a first support tube 2, and a first guide seat 3. In actual processing, the pull rope 1 can be a steel wire rope or a nylon rope. Considering the service life of the pull rope 1, in this specific embodiment, the pull rope 1 is preferably made of steel wire rope. The first support tube 2 is made of aluminum alloy, which is lightweight and has good structural strength. The first guide seat 3 can be made of plastic. The first guide seat 3 is sleeved inside the front end of the first support tube 2. The first support tube 2 can drive the first guide seat 3 to move synchronously. That is, when the first support tube 2 moves as a whole, the first support tube 2 can drive the first guide seat 3 to move synchronously. The two free connection ends of the pull rope 1 are both pulled out from the rear of the first support tube 2, and one free connection end 11 is located behind the rear of the first support tube 2, while the other free connection end 12 is located in front of the rear of the first support tube 2. Specifically, the two free connection ends of the pull rope 1 are... The rear free connection end 11 and the front free connection end 12 are respectively. Both the rear free connection end 11 and the front free connection end 12 are pulled out from the rear of the first support tube 2. After the rear free connection end 11 is pulled out, it can be fixedly connected to the component located behind the first support tube 2. After the front free connection end 12 is pulled out, it turns 180 degrees and moves a certain distance towards the front of the first support tube 2. When the pull rope 1 is in a taut state and the rear free connection end 11 and the front free connection end 12 are fixed accordingly, when the first support tube 2 is dragged to move back and forth within a certain range, the pull rope 1 is always in a taut state under the push of the rear of the first support tube 2 or the first guide seat 3. This achieves the orderly guidance and arrangement of the pull rope 1, so that when the telescopic rod internal traction variable pitch structure is applied to other mechanisms, the pull rope 1 will not be scattered, ensuring the smooth movement of the first support tube 2.

[0021] During the forward and backward movement of the first support tube 2, the middle section of the pull rope 1 moves relative to the rear of the first support tube 2 and the first guide seat 3. To reduce the wear of the pull rope 1 on the rear of the first support tube 2 and the first guide seat 3, a second guide seat 4 is provided at the rear of the first support tube 2. The pull rope 1 passes through the second guide seat 4. Specifically, a first through hole 41 communicating with the interior of the first support tube 2 is provided on the second guide seat 4. Both free connecting ends of the pull rope 1 are pulled out from the first through hole 41. A first guide wheel is provided on the upper side inside the first through hole 41 to guide the front free connecting end 12. Further, a second guide wheel 33 is provided at the rear of the first guide seat 3. The second guide wheel 33 is used to assist in the steering guidance of the pull rope 1. When the first support tube 2 moves, both the first guide wheel and the second guide wheel 33 roll and rub against the pull rope 1, thereby reducing the wear on the pull rope 1 and improving its service life.

[0022] Based on the above embodiment, in order to facilitate the storage of the pull rope 1 located outside the first support tube 2, a first arc-shaped groove 21 for accommodating the pull rope 1 is provided on the outer wall of the first support tube 2. In actual application, the pull rope located between the rear part of the first support tube 2 and the front free connection end 12 of the pull rope 1 is located in the arc-shaped groove 12, so that when the first support tube 2 is sleeved in other sleeves, the pull rope located outside the first support tube 2 will not be squeezed.

[0023] This utility model also provides a multifunctional pickup device (such as...). Figure 4 , Figure 5As shown), including the telescopic rod internal traction variable distance structure according to the above embodiment, the multi-functional pickup also includes an operating handle 5, a second support tube 6, a pickup clamp, and a telescopic adjustment and locking mechanism. The operating handle 5 is an existing operating handle on existing multi-functional pickups, which mainly includes a fixed handle and a movable handle 51. The upper part of the movable handle 51 is hinged to the fixed handle, and the movable handle 51 can swing back and forth around the hinge axis. The first support tube 2 is slidably sleeved in the second support tube 6. The operating handle 5 is located at the rear of the second support tube 6, that is, the front part of the fixed handle of the operating handle 5 is fixedly connected to the rear part of the second support tube 6. The free connection end of the pull rope 1 located behind the rear part of the first support tube 2 (i.e., The rear free connection end 11) is connected to the movable handle 51 of the operating handle 5. By pulling the movable handle 51 backward, the rear free connection end 11 can be moved backward. The pickup chuck includes a mounting base 71, a connecting rod 72, a reset mechanism, and a pickup arm 74. The mounting base 71 is fixedly sleeved on the front of the first support tube 2. The upper part of the connecting rod 72 is sleeved in the mounting base 71. The rear part of the connecting rod 72 is fixedly connected to the front of the first guide seat 3. Specifically, a first insertion hole 31 is provided at the front of the first guide seat 3. The rear part of the connecting rod 72 is sleeved in the first insertion hole 31. A second pin hole 721 is provided at the rear of the connecting rod 72. A second pin hole 721 is provided on the side wall of the first insertion hole 31. A first pin hole 32 is provided that penetrates the first guide seat 3 radially. The first pin hole 32 is adapted to the second pin hole 721. When the rear part of the connecting rod 72 is inserted into the first insertion hole 31, a pin is inserted into the first pin hole 32 and the second pin hole 721 to achieve a fixed connection between the connecting rod 72 and the first guide seat 3. The reset mechanism can always apply a forward thrust to the connecting rod 72. The rear outer ends of the two picking arms 74 are hinged to the front part of the connecting rod 72. Specifically, a hinged circular plate 742 is fixedly provided on the rear outer side of the picking arm 74. The two hinged circular plates 742 and the front end of the connecting rod 72 are hinged together by a first hinge shaft 75. Each picking arm 74 is close to the first guide seat 3. The front part of the connecting rod 72 is hinged to the mounting base 71. By pulling the connecting rod 72 backward, the front parts of the two picking arms 74 can be brought closer to each other. Specifically, a first elongated hole 743 located on the outer side of the rear part of the picking arm 74 is provided outside the hinged circular plate 742. A second pin 76 adapted to the first elongated hole 743 is fixedly provided on the mounting base 71. The second pin 76 passes through the corresponding first elongated hole 743. When the connecting rod 72 is pulled backward, the front end of the connecting rod 72 pulls the two hinged circular plates 742 to swing downward, thereby realizing the rotation of the two picking arms 74 around the corresponding second pin 76. The relative rotation of the two picking arms 74 then realizes the close clamping action.The free connecting end (and front free connecting end 12) of the pull rope 1 located at the rear front of the first support tube 2 is fixedly locked to the front outer side of the second support tube 6. The telescopic adjustment locking mechanism is used to lock the first support tube 2 and the second support tube 6. After the first support tube 2 is locked onto the second support tube 6, pulling the movable handle 51 backward will cause the front parts of the two picking arms 74 to move closer together, thereby achieving the clamping function. When the movable handle 51 is released, the two picking arms 74 and the movable handle 51 return to their initial positions under the pushing action of the spring 73.

[0024] Based on the above embodiments, the specific implementation of the reset mechanism is as follows: the reset mechanism is a spring 73, a limiting step 722 is provided at the front of the connecting rod 72, the spring 73 is sleeved on the connecting rod 72 and the spring 73 is clamped between the limiting step 722 and the horizontal plate 711 of the mounting base 71. The spring 73 always applies a forward pushing force to the connecting rod 72. In actual application, after the clamping work of the two picking arms 74 is completed and the movable handle 51 is released, the spring 73 pushes the connecting rod 72 forward, thereby causing the two picking arms 74 to return to the initial working position, and then realizing the reset of the picking arms 74.

[0025] Based on the above embodiments, the specific implementation of the telescopic adjustment and locking mechanism is as follows: The telescopic adjustment and locking mechanism includes a telescopic rod plastic buckle 81 and a reinforcing sleeve 82. The telescopic rod plastic buckle 81 is a known mature technology product in the existing technical field. In this specific embodiment, the telescopic rod plastic buckle 81 can be a buckle produced by the brand Taihao, with a specification of 3.1-3.4CM. The telescopic rod plastic buckle 81 includes a fixed sleeve 811 and a movable sleeve 812. The movable sleeve 812 is sleeved on the front part of the fixed sleeve 811. The rear part 8112 of the fixed sleeve of the telescopic rod plastic buckle 81 is fixedly sleeved on the front part of the second support tube 6. The front part 8111 of the fixed sleeve of the telescopic rod plastic buckle 81 is sleeved on the outside of the first support tube 2. In practical applications, the movable sleeve 812 is tightened or loosened on the front part 8111 of the fixed sleeve to lock or release the first support tube 2 and the second support tube 6. The reinforcing sleeve 82 is sleeved on the outside of the rear part 8112 of the fixed sleeve of the telescopic rod plastic buckle 81. The reinforcing sleeve 82 can improve the connection stability between the rear part 8112 of the fixed sleeve and the second support tube 6. Based on the above embodiment, the specific implementation of the fixed positioning of the front free connection end 12 on the side wall of the second support tube 6 is as follows: a T-shaped groove 8113 is provided on the side wall of the rear part 8112 of the fixed sleeve. The free connection end (i.e., the front free connection end 12) located in front of the rear part of the first support tube 2 penetrates the side wall of the second support tube 6. A positioning block 121 is fixedly provided on the free connection end (i.e., the front free connection end 12) located in front of the rear part of the first support tube 2. The reinforcing sleeve 82 presses and fixes the positioning block 121 in the T-shaped groove 8113.

[0026] In practical applications, the rear free connection end 11 is fixedly connected using the movable handle 51, and the front free connection end 12 is pressed and fixed using the T-groove 8113 and the reinforcing sleeve 82. Therefore, when the first support tube 2 moves back and forth, the pull rope 1 can always remain taut. At the same time, when the first support tube 2 remains stationary, the two picking arms 74 can be brought closer to each other by pulling the movable handle 51 backward. This allows the multi-functional picker to be extended and retracted while also ensuring the clamping function of the two picking arms 74.

[0027] Based on the above embodiment, in order to improve the clamping stability of the object when the two picking arms 74 are close to each other, a picking disk 741 is fitted on the front of the picking arm 74.

[0028] In this utility model, "left" and "right" are relative positions used for the convenience of describing positional relationships, and therefore cannot be understood as absolute positions as a limitation on the scope of protection.

[0029] Except for the technical features described in the specification, all other technologies are known to those skilled in the art.
