[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure. Example

[0023] Reference Figure 1-4 As shown: a walkway brick removal tool for municipal construction, including an auxiliary rod 1, a support rod 6 is fixedly connected to the bottom of the auxiliary rod 1, the support rod 6 is connected to an extension rod 9 by a thread, a removal mechanism is arranged on one side of the support rod 6, the removal mechanism includes a sleeve rod 2, a pry hook body 3 and a limit groove 16, one end of the sleeve rod 2 is fixedly connected to the pry hook body 3, one side of the pry hook body 3 is fixedly connected to a limit block 15, the limit groove 16 is arranged on one side of the pry hook body 3, a sliding rod 5 is inserted through the sleeve rod 2, the sliding rod 5 is slidably connected to the sleeve rod 2, an inner rod 8 is slidably connected to the sleeve rod 2, a positioning hole 17 is provided on one side of the inner rod 8 and a limiting pin 14 is inserted in the positioning hole 17, one end of the inner rod 8 is hinged with a connecting piece 11, and one side of the connecting piece 11 is slidably connected to the auxiliary rod 1.

[0024] By using the threaded connection between the extension rod 9 and the support rod 6, the extension length of the extension rod 9 can be adjusted, and then the bottom end of the extension rod 9 is used to contact the ground or another brick body to support the bottom of the auxiliary rod 1, thereby improving the stability of the auxiliary rod 1 when in use, and making the auxiliary rod 1 stable and simulated. The limit block 15 can increase the contact area between the pry hook body 3 and the top of the brick body. The limit groove 16 is arranged on one side of the pry hook body 3, which can increase the tightness of the connection between the pry hook body 3 and the side wall of the brick body, so that the side wall of the brick body and the pry hook body 3 are engaged, thereby reducing the sliding of the brick body when it is removed. The inner rod 8 is slidably connected with the sleeve rod 2 to form a telescopic structure, which is convenient for changing the extension length of the pry hook body 3 and removing bricks of different sizes. The limit pin 14 is installed in the positioning hole 17, which can lock the position of the inner rod 8 and improve the stability of the inner rod 8 when in use. The connecting piece 11 can be used to support one side of the inner rod 8, and then the auxiliary rod 1 is used to improve the support effect of the inner rod 8, so as to prevent the pry hook body 3 from tipping over when in use, thereby improving the stability of the entire tool when in use. Example

[0025] like Figure 2 and Figure 3 As shown, the connecting piece 11 is connected to a threaded rod 13 through a thread, one end of the threaded rod 13 passes through the fixed block 12, one end of the threaded rod 13 is rotatably connected to the inner wall of the auxiliary rod 1, and one end of the threaded rod 13 passes through the side wall of the auxiliary rod 1, and a clamping sleeve 7 is clamped on the outer ring surface of the sliding rod 5. The cross-section of the sliding rod 5 is U-shaped, and a spring telescopic rod 10 is fixedly connected to the bottom of the clamping sleeve 7, and one end of the spring telescopic rod 10 is fixedly connected to the support block 4.

[0026] The rotation of the threaded rod 13 can drive the connecting piece 11 to move inside the auxiliary rod 1, thereby changing the distance between the two sleeve rods 2 and adjusting the contact position between the pry hook body 3 and the brick body. When the connecting piece 11 moves, the auxiliary rod 1 can guide the movement of the connecting piece 11. The slide rod 5 passes through the two sleeve rods 2 and can guide the movement of the sleeve rod 2. The clamping sleeve 7 facilitates the connection between the spring telescopic rod 10 and the slide rod 5. The spring telescopic rod 10 can assist in adjusting the height of the support block 4, so that the bottom of the support block 4 overlaps the brick body, and the bottom of the slide rod 5 is supported and reinforced. The clamping sleeve 7 is easy to install and disassemble on the slide rod 5, and can be quickly removed when the tool is not in use, further reducing the volume of the entire tool.

[0027] The method of use and working principle of this device are as follows: first, adjust the protruding length of the inner rod 8 inside the sleeve rod 2, then synchronously insert the ends of the two pry hook bodies 3 into the gaps of the walkway bricks, and then move the pry hook body 3 to the side close to the brick body. At this time, the limiting groove 16 is engaged with the side wall of the brick body, and the bottom of the limiting block 15 overlaps the brick body. At this time, the brick body and the pry hook body 3 are tightly fitted. Then, rotate the extension rod 9 at the bottom of the support rod 6, adjust the protruding length of the extension rod 9, so that the bottom of the extension rod 9 overlaps the ground or another brick body to support the bottom of the auxiliary rod 1, and then rotate the threaded rod 13 on one side of the auxiliary rod 1. The threaded rod 13 is provided with threads on both sides of the fixed block 12. When the threaded rod 13 rotates, it can drive the connecting piece 11 to move inside the auxiliary rod 1, and the sleeve rod 2 moves with the connecting piece 11, and the pry hook body 3 moves on one side of the brick body to assist in the separation of soil and the side wall of the brick body. At this time, the distance between the two sleeve rods 2 increases, and the pry hook body 3 and The contact position of the brick body changes and can fully contact with the brick body. After the adjustment is completed, hold the middle part of the auxiliary rod 1 to move the auxiliary rod 1 upward. At this time, the pry hook body 3 applies a force to the brick body to drive the brick body to move. At this time, the gap between the right side of the brick body and the ground increases. After the brick body is loosened, the left side tilts upward and separates from the ground to achieve removal. After removal, rotate the sleeve rod 2 on one side of the connecting piece 11 to keep the sleeve rod 2 and the support rod 6 level, remove the limit pin 14 on the sleeve rod 2, adjust the overall length of the sleeve rod 2 and the inner rod 8, and then insert the limit pin 14 into the positioning hole 17 to fix it, separate the sleeve 7 from the slide rod 5, rotate the extension rod 9 at the bottom of the support rod 6, further shorten the extended length of the extension rod 9, reduce the volume of the entire tool, and then separate the sleeve 7 from the slide rod 5 to achieve the removal of the sleeve 7 and the support block 4, so that the entire tool can be stored, the space occupied by the tool can be reduced, and the tool can be protected.

[0028] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
