[0002] The grip structure of active optical positioning probes mostly adopts a smooth outer wall or a simple anti-slip design, mainly to provide basic grip support for operators and assist in completing probe positioning operations. In general scenarios, it can meet basic usage needs.
[0003] However, the existing grip structure has shortcomings: it lacks a dedicated groove that fits the fingers, which can easily cause fatigue when holding it for a long time. The fit between the hand and the grip is not good. It does not provide a switchable grip mode, making it difficult to adapt to different hand sizes and usage habits. Overall usability and convenience need to be optimized. Utility Model Content
[0004] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide an active optical positioning probe that solves the problems of grip fatigue and insufficient adaptability of existing active optical positioning probe grip structures.
[0005] To address the problems in the existing technology, the technical solution of this utility model is as follows:
[0006] An active optical positioning probe includes a grip portion and a probe disposed in the middle of the bottom surface of the grip portion. The grip portion is provided with a grip groove structure adapted to hand gripping. The grip portion is also equipped with a detachable grip ring for assisting gripping. The grip ring and the grip portion are detachably connected by a snap-fit structure. The grip groove structure includes two first grip grooves opened on the left side of the grip portion and arranged sequentially from top to bottom, and a second grip groove opened on the right side of the grip portion and directly opposite the lower first grip groove. The second grip groove is symmetrically arranged with the lower first grip groove. Both the first and second grip grooves are concave in an arc-shaped surface. The inner walls of the first and second grip grooves are provided with multiple transversely extending anti-slip textures at equal intervals from top to bottom.
[0007] Optionally, the snap-fit structure includes a baffle plate disposed on the side of the grip ring near the grip portion. When installed, the baffle plate fits into the first grip groove or the second grip groove. An insert block is formed in the middle of the side of the baffle plate near the slot. A slot is provided in both the first and second grip grooves at the lower end. The slot is adapted to the insert block. A deformable first positioning protrusion is provided on the outer peripheral wall of the insert block. A positioning groove is provided on the inner wall of the slot corresponding to the position of the first positioning protrusion. The first positioning protrusion is hemispherical. The end of the insert block away from the grip ring is chamfered, and the opening of the slot is also chamfered.
[0008] Optionally, the head of the grip portion is provided with a placement groove for receiving the grip ring. The shape of the placement groove matches the shape of the grip ring. The inner wall of the placement groove is provided with a deformable second positioning protrusion for securing the grip ring in the placement groove. The second positioning protrusion is hemispherical, and the outer edge of the grip ring is provided with an arc-shaped chamfer.
[0009] Compared with the prior art, the advantages of this utility model are as follows:
[0010] 1. This utility model alleviates grip fatigue by setting an arc-shaped grip groove that conforms to the shape of the fingers on the grip part. With the addition of a detachable grip ring, it provides two optional operation methods: direct gripping through the grip groove and gripping with the grip ring. The anti-slip texture of the grip groove enhances the fit, allowing operators with different usage habits to operate conveniently, improving adaptability and effectively preventing grip slippage.
[0011] 2. This utility model features a chamfer at the opening of the insert and the slot, and a second positioning protrusion on the inner wall of the slot. The chamfer structure makes it easier for the grip ring insert to be inserted into the slot, and the second positioning protrusion can securely store the unused grip ring to prevent loss, making the disassembly and storage of the grip ring more convenient and further improving the overall ease of use.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] Please see Figures 1 to 7 This embodiment provides an active optical positioning probe, including a grip portion 1. A probe 2 is provided in the middle of the bottom surface of the grip portion 1. Two first grip grooves 3 are sequentially formed from top to bottom on the left side of the grip portion 1. A second grip groove 4 is formed on the right side of the grip portion 1, directly opposite to one of the first grip grooves 3 at the lower end. The second grip groove 4 is symmetrically arranged with the first grip groove 3 at the lower end. When the operator operates the probe 2, the thumb is placed in the second grip groove 4, and the middle finger and index finger are placed in the two first grip grooves 3 respectively. The first grip grooves 3 and the second grip groove 4 are both concave arc-shaped to fit the shape of the fingers, making the operation more comfortable.
[0022] Furthermore, multiple horizontally extending anti-slip textures 5 are formed on the inner walls of the first grip groove 3 and the second grip groove 4 at equal intervals from top to bottom. The anti-slip textures 5 increase the friction when the hand grips the grip, making it less likely to slip off the grip part 1. Compared with the traditional active optical probe 2, which has no groove structure on its outer wall that matches the hand, the grooves greatly improve the comfort and stability of operation.
[0023] If the grip groove is uncomfortable to use, the grip ring 7 can be used to hold the grip part 1. A slot 6 is provided in both the first grip groove 3 and the second grip groove 4 at the lower end. Two grip rings 7 are symmetrically arranged on both sides of the grip part 1. A baffle 8 is provided on the side of the grip ring 7 near the slot 6. When installed, the baffle 8 fits into the first grip groove 3 or the second grip groove 4. An insert 9 is formed in the middle of the side of the baffle 8 near the slot 6. When the grip ring 7 is installed on the grip part 1, the insert 9 is inserted into the slot 6. First positioning protrusions 1 are formed on the four side walls of the insert 9 that are connected and encircling each other. The first positioning protrusion 10 is hemispherical, and the inner wall of the slot 6 is provided with a positioning groove 11 corresponding to the position of the first positioning protrusion 10. When installing the grip ring 7, the insert 9 is inserted into the slot 6, pressing the first positioning protrusion 10 to deform until it is fully inserted. The first positioning protrusion 10 is directly facing the positioning groove 11 and abutting against the inner wall of the positioning groove 11, thus completing the positioning work and completing the installation of the grip ring 7. Then the operator can insert their fingers into the grip ring 7 to operate the probe 2. This gripping method can effectively prevent the grip part 1 from slipping off the fingers during use and improve the stability of operation.
[0024] To ensure smooth insertion of the insert 9, the end of the insert 9 facing away from the baffle 8 is chamfered, and the opening of the slot 6 is also chamfered, which makes it easier to insert the insert 9.
[0025] When operating the grip section 1 using only the grip groove, a placement position for the grip ring 7 is required. Two placement grooves 12 are symmetrically formed at the head of the grip section 1, their shapes matching the grip ring 7. After removing the grip ring 7 from the slot 6, it is inserted into the placement groove 12. A second positioning protrusion 13, also hemispherical, is formed on the inner wall of the placement groove 12. During insertion, the second positioning protrusion 13 is compressed and deformed until the grip ring 7 is fully inserted into the placement groove 12. The second positioning protrusion 13 then returns to its original shape, securing the grip ring 7 within the groove 12. The operator can then operate the probe through the grip groove, ensuring the grip ring 7 is properly positioned and will not separate from the probe, reducing the probability of loss. Furthermore, the outer edges of the grip ring 7 are rounded and chamfered, which is more ergonomic and comfortable during operation.
[0026] 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.
