Detailed Implementation

[0022] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or components / elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0023] The gripping device of this utility model is described below with reference to the accompanying drawings.

[0024] Figure 1 This is a schematic diagram of the structure of a gripping device provided in one embodiment of this application; Figure 2 This is a partially enlarged view of a gripping device connected to the lower end of a cane, according to an embodiment of this application. Figure 3 This is a schematic diagram of the structure of the lower guide plate of a gripping device provided in one embodiment of this application; Figure 4 This is a schematic diagram of the structure of the upper guide plate of a gripping device according to an embodiment of this application. Figure 5 This is a partial enlarged view I of a gripping device provided in one embodiment of this application. Figures 1-5 As shown: The gripping device includes a housing 51. A lower guide plate 52 is connected to the lower end of the housing 51. The lower guide plate 52 has a lower support hole 522 at its center and several lower guide holes 521 along its center radius R. Gripping posts 53 are inserted into the lower guide holes 521. Supports 54 are fitted into the lower support holes 522. An upper guide plate 55 is fitted to the upper end of the gripping post 53. The upper guide plate 55 has an upper support hole 552 at its center and several upper guide holes 551 along its center radius distance not exceeding D. The upper end of the gripping post 53... The end is provided with a snap-fit ​​connector. The gripping post 53 is fitted with the upper guide hole 551 and snaps into the upper guide piece 55. The upper support hole 552 is fitted into the support post 54. The upper end of the snap-fit ​​connector of the gripping post 53 abuts against the upper baffle 56. The upper baffle 56 has a round hole in the middle. The support post 54 is fitted into the upper baffle 56 through the round hole. The lower end of the support post 54 is provided with a locking head 541 and the upper end is connected with a fixing head 542. The fixing head 542 abuts against and fixes the upper baffle 56. The upper part of the housing 51 is provided with a first snap-fit ​​hole 57.

[0025] Specifically,Figure 1 This refers to the state when the device is in its collapsed state. Figure 2 This is the open state during use. The upper guide plate 55 and the upper baffle 56 clamp the upper end of the gripping post 53. The upper end of the gripping post 53 can be a round head with a horizontally protruding planar surface, which is locked in the upper guide hole 551. The fixing head 542 above the support post 54 then clamps and fixes the upper baffle 56, so that when the user installs the gripping device 5, the entire internal component moves downward against the fixing head 542, causing the gripping post 53 to extend downward and form a gripping shape (such as...). Figure 2 (As shown).

[0026] In one embodiment of this application, the support column 54 is a long screw with a locking head 541 at the head, which limits the upper limit position of the retracted state; the fixing head 542 is a nut, which fixes the upper locking component; to prevent the nut from falling off, a welding process can be added after fixing.

[0027] It should be noted that, according to the embodiments in the accompanying drawings of this application, the so-called "several lower guide holes 521" are 4, and correspondingly, the gripping posts 53 inserted into the guide holes 521 are also 4, and the "several upper guide holes 551" are also 4.

[0028] The cane according to this application achieves a balance between gripping function and daily portability through innovative gripping device structure, telescopic joint locking mechanism and modular design. At the same time, it improves the practicality and terrain adaptability of the cane with a low-cost solution, effectively solving the pain point of insufficient gripping of traditional canes in complex road conditions.

[0029] According to one embodiment of this application, the distance D is less than the radius R, such that when the upper guide plate 55 is at the top, the angle α between the gripping post 53 and the support post 54 is less than the angle β between the gripping post 53 and the support post 54 when the upper guide plate 55 moves to the bottom.

[0030] Specifically, such as Figure 1 As shown, the gripping device 5 is in its retracted state at this time. Figure 2 The support column 54 in the gripping device 5 is pushed downward by the rod head 3. Because the distance D of the upper guide hole 551 from the center is less than the radius R of the lower guide hole 521 from the center, the included angle α in the retracted state is less than the included angle β in the use state. As a result, the gripping device 5 is in the open state when in use, thus forming a more stable gripping support.

[0031] According to one embodiment of this application, the lower end of the gripping post 53 is provided with a gripping head 531.

[0032] According to one embodiment of this application, the gripping head 531 is round.

[0033] Specifically, the dedicated grip head 531 facilitates insertion into the ground in muddy conditions, allowing the cane to grip the road firmly. The rounded head 531 ensures a suitable contact surface from all directions of insertion; its design reduces insertion resistance and improves grip efficiency.

[0034] According to one embodiment of this application, there are a total of 6 gripping posts 53; correspondingly, there are 6 upper guide holes 551 and 6 lower guide holes 521.

[0035] Specifically, the six grip pillars create a more stable structure, providing greater grip.

[0036] According to one embodiment of this application, the gripping post 53 has a notch 533 below the snap connector 532, which fits with the upper guide hole 551.

[0037] According to one embodiment of this application, the snap joint 532 of the gripping post 53 is flush with the end face below the notch 533.

[0038] Specifically, the notch 533 can be directly machined on a lathe, making the notch 533 recessed and matching the upper guide hole 552; the gripping post 53 is cylindrical, and after directly machining to form the notch 533, the clamping head 532 can be flush with the lower end face of the notch, which is simple and convenient to process and has low cost.

[0039] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this utility model are within the protection scope of this utility model.
