[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Example: A novel bearing lifting crowbar, such as Figure 1 - Figure 4 As shown, the device includes a pry bar connecting seat 1, which is an L-shaped metal block. A rocker arm 2 is located at the lower end of the pry bar connecting seat 1, and an L-shaped alloy steel metal plate is located at the lower end of the rocker arm 2. One end of the rocker arm 2 has a shovel-shaped insertion tip for easy insertion into the bottom of the heavy object. The lower end of the pry bar connecting seat 1 is fixedly welded to the rocker arm 2. A mounting post 3, made of alloy steel, is located at one end of the pry bar connecting seat 1. The mounting post 3 is perpendicular to the mounting direction of the pry bar connecting seat 1. Support bearings 4 are located at both ends of the outer side of the mounting post 3, and are sleeved on the outer side of the mounting post 3, rotatably connected to it. Mounting grooves are located on both sides of the mounting post 3. Limiting springs 5, C-shaped, are located at both ends of the outer side of the mounting post 3, and are engaged inside the mounting grooves on the outer side of the mounting post 3. The outer diameter of the limiting springs 5 ​​is larger than that of the supporting springs. The bearing 4 is limited by a retaining spring 5 to prevent it from falling off the top of the mounting column 3. A pry bar 6 is provided at one end of the prying connector 1. The pry bar 6 is a thickened seamless steel pipe. An inclined angle is formed between the pry bar 6 and the rocker 2, with the angle being greater than 90 degrees and less than 160 degrees, making it easier to pry heavy objects. The lower end of the pry bar 6 is fixedly welded to the prying connector 1. Two sets of sliding grooves 7 are provided on the outer side of the pry bar 6, and these grooves are parallel to each other. An anti-slip mechanism 8 is provided on the outer side of the pry bar 6, fitted onto the outer side of the pry bar 6. The inner side of the anti-slip mechanism 8 is adjustable and can be installed inside the sliding groove 7. During use, the position of the anti-slip mechanism 8 can be changed along the sliding groove 7, making it easier to grip. By setting the anti-slip mechanism 8, the comfort of the worker's grip can be increased, preventing slippage due to sweating during the prying process.

[0023] Furthermore, the anti-slip mechanism 8 includes a sliding sleeve 9, which is a hollow shell. The shape of the sliding sleeve 9 is adapted to the pry bar 6. The sliding sleeve 9 is sleeved on the outside of the pry bar 6. A handle 10 is provided on the outside of the sliding sleeve 9. The handle 10 is made of EVA anti-slip foam and is a cylindrical hollow shell. The handle 10 is sleeved on the outside of the sliding sleeve 9, and the inner wall of the handle 10 is fixedly bonded to the sliding sleeve 9. Adjustment seats 11 are provided at the upper and lower ends of the sliding sleeve 9. The adjustment seats 11 are annular metal rings. The adjustment seats 11 are sleeved on the outside of the pry bar 6. One end of the adjustment seat 11 is fixedly connected to the sliding sleeve 9. The interior of the adjustment seat 11 is relatively... A mounting base 13 is provided at the position of the sliding groove 7. The mounting base 13 is a U-shaped metal base with its opening facing the sliding groove 7. A roller 14 is provided inside the mounting base 13. The center of the roller 14 is movably connected to the mounting base 13 through a rotating shaft. One end of the roller 14 is in contact with the inner wall of the sliding groove 7. A grip groove 12 is provided on the outer surface of the handle 10. The grip groove 12 can increase the comfort of the operator's grip. Limiting components 15 are provided at both ends of the outer side of the adjusting seat 11 relative to the position of the sliding groove 7. One end of the limiting component 15 extends through the adjusting seat 11 into the sliding groove 7. By setting the limiting component 15, the anti-slip mechanism 8 can be limited.

[0024] Furthermore, the limiting component 15 includes an adjusting rod 16, which is a metal connecting rod. The adjusting rod 16 is threadedly connected to the adjusting seat 11, and one end of the adjusting rod 16 extends into the adjusting seat 11. A pressure plate 17 is provided inside the adjusting seat 11 relative to the adjusting rod 16. The pressure plate 17 is a circular metal plate, and one end of the pressure plate 17 is fixedly connected to the adjusting rod 16. The diameter of the pressure plate 17 is smaller than the width of the sliding groove 7, and the pressure plate 17 can be inserted into the sliding groove 7. A positioning ball 18 is provided at the end of the pressure plate 17 near the sliding groove 7. The positioning ball 18 is an elastic rubber ball made of wear-resistant material, and one end of the positioning ball 18 is fixedly connected to the pressure plate 17. In use, by rotating the adjusting rod 16, the adjusting rod 16 pushes the positioning ball 18 at the lower end of the pressure plate 17 to abut against the bottom surface inside the sliding groove 7, thereby limiting the grip 10 on the outside of the sliding sleeve 9.

[0025] It should be noted that this utility model is a new type of bearing lifting pry bar. In use, first rotate the adjusting rod 16 in the opposite direction. During the movement, the adjusting rod 16 causes the positioning ball 18 to not contact the bottom surface of the sliding groove 7. Then, push the handle 10 along the sliding groove 7 to move to the appropriate position. The mounting seat 13 and roller 14 inside the adjusting seat 11 can make the handle 10 move more smoothly. After the position is adjusted, rotate the adjusting rod 16. The adjusting rod 16 pushes the positioning ball 18 at one end of the pressure plate 17 to abut against the bottom surface of the sliding groove 7, thereby limiting the handle 10 on the outside of the sliding sleeve 9. The grip groove 12 on the outside of the handle 10 can increase the grip comfort. After the anti-slip mechanism 8 is adjusted to the appropriate position, the worker holds the anti-slip mechanism 8 on the outside and pushes the supporting bearing 4 to rotate. Insert one end of the pry bar 2 into the lower end of the heavy object, and then lift the heavy object by using the pry bar 6. By incorporating the anti-slip mechanism 8, the grip comfort of the pry bar 6 is improved. The handle 10 can absorb sweat from the worker's hands, preventing slippage during prying and facilitating daily use of the pry bar. The limiting component 15 can limit the anti-slip mechanism 8, preventing it from wobbling during prying. It can also be adjusted according to the grip position, enhancing its practicality.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
