[0018] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0019] In this disclosure, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" generally refer to the upper, lower, top, and bottom of the corresponding component in its operational state in the direction of gravity, while "inner" and "outer" refer to the inner and outer contours relative to the component or structure itself. Furthermore, it should be noted that terms such as "first" and "second" are used to distinguish one element from another and do not indicate sequence or importance. Additionally, in the description with reference to the accompanying drawings, the same reference numerals in different drawings denote the same element.

[0020] like Figure 1-2As shown, this disclosure provides a pin removal device, including: an adjustable length slide bar 1 having a first end 11 and a second end 12 opposite to the first end 11, a connector 3 being provided at the first end 11 for connecting with a pin, and a limiting member 2 being provided at the second end 12; and an impact member 4 being coaxially sleeved on the slide bar 1 and slidably connected to the slide bar 1 so as to slide between the connector 3 and the limiting member 2.

[0021] With the above technical solution, the slide bar 1 is slidably connected to the impact member 4. When it is necessary to remove the pin, the connecting member 3 is connected to the end of the pin, and the sliding impact member 4 is made to impact the limiting member 2 on the side away from the connecting member 3. The impact force is used to pull out the pin. It is convenient to exert force even in narrow spaces, and the operation is convenient. Moreover, the length of the slide bar 1 can be adjusted and set, which is suitable for different spaces and can be used even in narrow spaces.

[0022] As an optional implementation method, such as Figure 2 As shown, the slide bar 1 includes multiple connecting segments 13, which are detachably connected. The length of the slide bar 1 can be adjusted by installing different numbers of connecting segments 13, making it suitable for different spaces. This also keeps the diameter of the slide bar 1 consistent. If the slide bar 1 is set as a telescopic rod, the diameter of the slide bar 1 will change and it will be inconvenient to fix.

[0023] Optionally, such as Figure 2 As shown, one end of the connecting segment 13 is provided with a first connecting part 5, and the other end is provided with a second connecting part 6 that is detachably connected to the first connecting part 5. Two adjacent connecting segments 13 are detachably connected through the first connecting part 5 and the second connecting part 6. Each connecting segment 13 has a first connecting part 5 and a second connecting part 6 at both ends. The connecting segment 13 is connected to the second connecting part 6 on another connecting segment 13 through the first connecting part 5. Multiple connecting segments 13 are connected in sequence, and the number of connecting segments 13 can be adjusted arbitrarily.

[0024] Optionally, such as Figure 2 As shown, the first end 11 is provided with a first connecting part 5, and one end of the limiting member 2 is provided with a second connecting part 6. The limiting member 2 is detachably connected to the slide rod 1 for easy replacement and maintenance. The limiting member 2 is connected by the first connecting part 5 provided on the slide rod 1, so the connecting section 13 does not need to be set separately and a uniform connecting section 13 can be used. Of course, in other embodiments, the first end 11 can also be provided with a second connecting part 6, and one end of the limiting member 2 can be provided with a first connecting part 5.

[0025] Optionally, such as Figure 2As shown, the second end 12 is provided with a second connecting part 6, and one end of the connecting member 3 is provided with a first connecting part 5. The connecting member 3 is detachably connected to the slide rod 1, and different connecting members 3 can be replaced to suit different pins. The connecting member 3 is provided with a first connecting part 5, and the detachable connection can be achieved by using the second connecting part 6 on the connecting segment 13. In this way, the connecting segment 13 does not need to be set separately, and a uniform connecting segment 13 can be used. Of course, in other embodiments, the second end 12 can also be provided with a first connecting part 5, and one end of the connecting member 3 can be provided with a second connecting part 6, that is, the position of the connecting member 3 can be interchanged with that of the limiting member 2.

[0026] Optionally, such as Figure 2 As shown, the first connecting part 5 is constructed as a first screw, and the second connecting part 6 is constructed as a first screw hole. The multiple connecting sections 13 are threadedly connected to the first screw hole through the first screw. The first screw extends into the first screw hole, so that there will be no gap between the two connecting sections 13 and the overall diameter of the slide rod 1 is consistent. Moreover, the threaded connection is convenient to operate and the structure is simple.

[0027] As an optional implementation method, such as Figure 2 As shown, the end of the pin is provided with a second screw hole, and the connector 3 includes a second screw 31 corresponding to the second screw hole. The connector 3 is connected to the pin through the second screw 31. The pin is a pin with a second screw hole at its end. The second screw 31 of the connector 3 is threadedly connected to the second screw hole, thereby connecting the connector 3 to the pin.

[0028] As an optional implementation method, such as Figure 1 As shown, the impact member 4 is constructed as a sleeve with a through hole located at the center. The sliding rod 1 passes through the through hole, and the sleeve impact member 4 is fitted onto the sliding rod 1 to impact the limiting member 2. The impact member 4 is designed as a sleeve, which facilitates operation and ensures that the force impacting the limiting member 2 is relatively uniform in all directions. The sleeve is recessed inward at the middle position to form a handhold, which is convenient for the operator to hold and operate. Of course, in other embodiments, the impact member 4 can also be a slider, with a slide rail provided on the sliding rod 1, and the slider is slidably connected to the sliding rod 1 through the slide rail.

[0029] Optionally, such as Figure 1-2 As shown, the connector 3 includes a limiting plate 32. The outer diameter of the limiting plate 32 is larger than the inner diameter of the through hole. The limiting plate 32 is used to limit the impact member 4 at the second end 12. The limiting plate 32 is arranged perpendicularly to the slide rod 1. The first connecting part 5 and the second screw 31 on the connector 3 are arranged opposite to each other on both sides of the limiting plate 32.

[0030] Optionally, such as Figure 1-2As shown, the limiting component 2 is a handle. The outer diameter of the handle is larger than the inner diameter of the through hole. While limiting the position, the limiting component 2 also serves as a handle. The handle is cylindrical, which makes it convenient for workers to support the device when using it.

[0031] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0032] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0033] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
