A novel positioning component for a telescopic harvesting tool

Abstract

This utility model discloses a novel positioning component for a telescopic harvesting tool, including a component body with an eccentric column installed inside. By setting the eccentric column, when using the component body, a plastic sleeve and an anti-slip sleeve are installed on the side of the eccentric column. One end of the wide side of the anti-slip sleeve is fitted onto one end of the narrow side of the eccentric column, allowing the anti-slip sleeve to be installed in an installation groove. One end of a connecting column is installed in a suitable round tube, and a sleeve with a diameter larger than the round tube is fitted onto the side of the round tube. After the component body is installed at one end of the round tube, pushing the sleeve moves it to completely cover the component body. At this time, rotating the round tube installed at one end of the connecting column causes the anti-slip sleeve to slide along the side of the eccentric column. As the wide side of the anti-slip sleeve moves along the side of the eccentric column, it causes the side anti-slip sleeve to be squeezed out, exceeding the diameter of the component body, and then abutting against the inner wall of the sleeve, fixing the position of the sleeve after movement, thus achieving the effect of adjusting telescopic movement.

Description

Technical Field

[0001] This utility model relates to the field of positioning component technology, specifically a novel positioning component for a telescopic harvesting tool. Background Technology

[0002] Telescopic harvesting tools are widely used in agricultural and daily operations such as fruit and vegetable picking, garden pruning, and retrieving items from heights because they can effectively expand the working range and reduce labor intensity. These tools are usually made of multiple sections of tubing with different diameters connected together, and the overall extension and retraction of the tool is achieved by adjusting the relative length of each section of tubing.

[0003] Existing common telescopic positioning mechanisms mostly employ threaded tightening or flexible pin hole engagement. While threaded tightening provides a large locking force, adjustment requires repeated rotation, a cumbersome and time-consuming process with low efficiency. Furthermore, frequent adjustments can cause thread wear, leading to a decrease in locking force. Flexible pins require multiple pre-drilled positioning holes in the pipe wall, which not only limits the continuity of length adjustment, restricting it to stepped adjustments and reducing adaptability, but drilling can also weaken the pipe material and pose a potential risk of breakage. Therefore, a new positioning component for telescopic harvesting tools is needed to meet people's needs. Utility Model Content

[0004] The purpose of this invention is to provide a novel positioning component for a telescopic harvesting tool to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel positioning component for a telescopic harvesting tool, comprising a component body, an eccentric column installed inside the component body, an installation groove formed on the side of the component body, a fixing plate installed at one end of the eccentric column, a plastic sleeve installed on the side of the installation groove, an anti-slip sleeve installed on the side of the plastic sleeve, a narrow anti-slip sleeve edge formed at one end of the anti-slip sleeve, a wide anti-slip sleeve edge formed at the other end of the anti-slip sleeve, and a narrow eccentric column edge formed at the end of the eccentric column near the wide anti-slip sleeve edge.

[0006] Preferably, the plastic sleeve has multiple plastic slots inside, and the anti-slip sleeve is installed on the side of the plastic sleeve through the plastic slots.

[0007] Preferably, a socket post is installed at the bottom of the component body, and the diameter of the socket post is smaller than the diameter of the component body.

[0008] Preferably, the wide side of the anti-slip sleeve is installed at the end of the eccentric column near the narrow side of the eccentric column, and the plastic sleeve abuts against the side of the eccentric column.

[0009] Preferably, the anti-slip sleeve abuts against the fixing plate on the side near the eccentric column, and the plastic sleeve and the anti-slip sleeve are slidably installed in the mounting groove.

[0010] Preferably, the anti-slip sleeve is made of rubber, and the sides of the anti-slip sleeve have a certain amount of friction.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] (1) By setting an eccentric column and mounting groove, this utility model allows the plastic sleeve and anti-slip sleeve to be installed on the side of the eccentric column when the main body of the component is used. One end of the wide side of the anti-slip sleeve is fitted onto one end of the narrow side of the eccentric column, so that the anti-slip sleeve is installed in the mounting groove. One end of the sleeve column is installed in the matching round tube. A sleeve with a diameter larger than the round tube is fitted on the side of the round tube. When the main body of the component is installed on one end of the round tube, the entire main body of the component is covered by pushing the sleeve to move. At this time, rotating the round tube installed on one end of the sleeve column causes the anti-slip sleeve to slide on the side of the eccentric column. When the wide side of the anti-slip sleeve moves along the side of the eccentric column, it will cause the side anti-slip sleeve to be squeezed out, exceeding the diameter of the main body of the component, and then abutting against the inner wall of the sleeve, fixing the position of the sleeve after movement, and playing the role of adjusting the expansion and contraction.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1: Please refer to Figure 1-4This utility model provides a technical solution: a novel positioning component for a telescopic harvesting tool, comprising a component body 1, an eccentric column 2 installed inside the component body 1, an installation groove 3 on the side of the component body 1, a fixing plate 4 installed at one end of the eccentric column 2, a plastic sleeve 5 installed on the side of the installation groove 3, an anti-slip sleeve 6 installed on the side of the plastic sleeve 5, an anti-slip sleeve narrow edge 8 at one end of the anti-slip sleeve 6, an anti-slip sleeve wide edge 9 at the other end of the anti-slip sleeve 6, an eccentric column narrow edge 10 at the end of the eccentric column 2 near the anti-slip sleeve wide edge 9, multiple plastic slots 7 inside the plastic sleeve 5, the anti-slip sleeve 6 installed on the side of the plastic sleeve 5 through the plastic slots 7, a connecting column 11 installed at the bottom of the component body 1, the diameter of the connecting column 11 being smaller than the diameter of the component body 1, the anti-slip sleeve wide edge 9 installed at the end of the eccentric column 2 near the eccentric column narrow edge 10, the plastic sleeve 5 abutting against the side of the eccentric column 2, and the anti-slip sleeve 6 abutting against the side of the eccentric column 2. The side of the near-eccentric column 2 abuts against the fixing plate 4. The plastic sleeve 5 and the anti-slip sleeve 6 are slidably installed in the mounting groove 3. The anti-slip sleeve 6 is made of rubber and has a certain friction on its side. The anti-slip sleeve 6 is installed on the plastic sleeve 5 through the plastic slot 7 to form a whole. The plastic sleeve 5 is installed on the side of the eccentric column 2. During installation, one end of the wide side 9 of the anti-slip sleeve 6 is placed on one end of the narrow side 10 of the eccentric column 2, so that the anti-slip sleeve 6 is installed in the mounting groove 3. At this time, the side of the anti-slip sleeve 6 exceeds the diameter of the component body 1 by a certain distance. One end of the sleeve column 11 is installed in the matching round tube. The diameter of the round tube is the same as the diameter of the component body 1. A sleeve with a diameter larger than the round tube is sleeved on the side of the round tube. After the component body 1 is installed at one end of the round tube, the component body 1 is completely covered by pushing the sleeve, so that the component body 1 serves as the connection point between the round tube and the sleeve.

[0022] The working principle is as follows: When using the main body 1, the anti-slip sleeve 6 is installed on the plastic sleeve 5 through the plastic slot 7 to form a whole. The plastic sleeve 5 is installed on the side of the eccentric column 2. During installation, one end of the wide side 9 of the anti-slip sleeve 6 is placed on one end of the narrow side 10 of the eccentric column 2, so that the anti-slip sleeve 6 is installed in the mounting groove 3. At this time, the side of the anti-slip sleeve 6 exceeds the diameter of the main body 1 by a certain distance. One end of the connecting column 11 is installed in a matching round tube. The diameter of the round tube is the same as the diameter of the main body 1. A sleeve with a diameter larger than the round tube is fitted on the side of the round tube. After the main body 1 is installed on one end of the round tube, the entire main body 1 is covered by pushing the sleeve. The main body 1 of the component serves as the connection between the round tube and the sleeve. At this time, the round tube installed at one end of the rotatable sleeve post 11 drives the anti-slip sleeve 6 to slide on the side of the eccentric post 2. When the wide side 9 of the anti-slip sleeve moves along the side of the eccentric post 2, one end of the anti-slip sleeve 6 abuts against the inner wall of the sleeve, and the other end moves along the side of the eccentric post 2. After rotating a certain angle, as shown in the fixed plate 4, the side of the anti-slip sleeve 6 is squeezed out, exceeding the diameter of the main body 1 of the component, and then abuts against the inner wall of the sleeve. The friction of the anti-slip sleeve 6 prevents the sleeve from sliding, thereby fixing the position of the sleeve after movement. After rotating in the opposite direction, the limit on the collar is canceled. At this time, the sleeve can be pulled to slide on the round tube. By adjusting the position of the sleeve, the overall tool extension and retraction can be adjusted.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
