AI Technical Summary
The existing pry bar is designed as a single piece, which is prone to slippage if not operated properly, resulting in safety hazards. Furthermore, it is prone to loss of center of gravity when working at heights, lacking adaptability and stability.
An adjustable pry bar was designed. Through components such as a support rod sleeve, a first bolt, a U-shaped support foot, an extension rod, a flat block, a second bolt, a sliding sleeve, and a locking bolt, the support height and rotation fulcrum can be adjusted. The length of the rod body is increased through an extension mechanism to enhance stability and applicability.
It enables flexible adjustment of the height and fulcrum position of the pry bar, enhancing stability and applicability, avoiding the risk of slippage, and improving operational safety and efficiency.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of pry bar technology, and in particular to an adjustable pry bar. Background Technology
[0002] The primary function of a pry bar is to lift and remove spikes. It works on the principle of leverage, using relatively little force to lift larger objects, making it particularly suitable for situations requiring labor-saving operations. For example, in railway maintenance, a pry bar can effectively lift track spikes, improving work efficiency and ensuring time- and labor-saving operations.
[0003] In existing technologies, most pry bars are one-piece designs. When using a pry bar, it is necessary to find a suitable fulcrum. Improper operation may cause the pry bar to slip off, resulting in personal injury. In addition, when working at heights, the slippage of the pry bar can cause loss of balance. Therefore, we propose an adjustable pry bar to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adjustable pry bar.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] An adjustable pry bar includes a support sleeve with a through hole at its bottom. A first bolt is rotatably connected to the inner wall of the through hole. A U-shaped support foot is rotatably fitted onto the outer wall of the first bolt. An extension rod is threaded onto the inner wall of the support sleeve. A flat block is fixedly connected to the top of the extension rod. A circular hole is formed on the outer wall of the flat block. A second bolt is rotatably connected to the inner wall of the circular hole. A sliding sleeve is rotatably fitted onto the outer wall of the second bolt. A rod body is slidably connected to the inner wall of the sliding sleeve. A threaded hole is formed on the outer wall of the sliding sleeve. A locking bolt is threaded onto the inner wall of the threaded hole. A rod head is fixedly connected to one end of the rod body. An extension mechanism is provided on the outer wall of the rod body.
[0007] Preferably, the growth mechanism includes a growth rod, one end of which has a threaded groove, and the inner wall of the threaded groove is threaded with a threaded head. One end of the threaded head is fixedly connected to one end of the growth rod. The growth mechanism increases the overall length of the rod. The other end of the growth rod has a threaded mating groove for adding more growth rods.
[0008] Preferably, both the first bolt and the second bolt have nuts threaded onto their outer walls, which limit the movement of the U-shaped support foot and the flat block.
[0009] Preferably, one end of the locking bolt is pressed against the outer wall of the rod body, thereby fixing the position of the rod body by setting the locking bolt.
[0010] Preferably, the outer wall of the growth rod is fitted with a silicone sleeve to increase hand comfort, and the outer wall of the silicone sleeve is provided with anti-slip texture.
[0011] Preferably, the outer wall of the U-shaped support foot is slidably connected to the outer wall of the support rod sleeve.
[0012] Compared with the prior art, the advantages of this utility model are:
[0013] This solution, by setting up a support rod sleeve, a first bolt, a U-shaped support foot, an extension rod, a flat block, a second bolt, a sliding sleeve, and a locking bolt, allows for adjustment of the support height of the pole body, as well as the position of the pole body's rotation fulcrum and the pole head. By setting up an extension mechanism, the overall length of the pole body can be increased, making it more convenient to use and increasing its applicability and stability.

[0021] Depend on Figures 1-3 As shown, an adjustable pry bar is disclosed, including a support rod sleeve 1. A through hole is provided at the bottom of the support rod sleeve 1. A first bolt 2 is rotatably connected to the inner wall of the through hole. A U-shaped support foot 3 is rotatably sleeved on the outer wall of the first bolt 2. The U-shaped support foot 3 supports the support rod sleeve 1 and the rod body 9. The outer wall of the U-shaped support foot 3 is slidably connected to the outer wall of the support rod sleeve 1.
[0022] The inner wall of the support rod sleeve 1 is threaded with an extension rod 4. The support rod sleeve 1 and the extension rod 4 are extended by a threaded connection. The top of the extension rod 4 is fixedly connected with a flat block 5. The outer wall of the flat block 5 has a round hole. The inner wall of the round hole is rotatably connected with a second bolt 6. The outer walls of the first bolt 2 and the second bolt 6 are both threaded with nuts.
[0023] The outer wall of the second bolt 6 is fitted with a sliding sleeve 7, and the inner wall of the sliding sleeve 7 is slidably connected to the rod body 9. The rod body 9 slides through the sliding sleeve 7 to adjust the position of the fulcrum of the rod body 9. The outer wall of the sliding sleeve 7 has a threaded hole, and the inner wall of the threaded hole is threadedly connected to a locking bolt 8. One end of the locking bolt 8 is pressed against the outer wall of the rod body 9. After the locking bolt 8 is rotated and locked, the rod body 9 is fixed in the sliding sleeve 7. One end of the rod body 9 is fixedly connected to a rod head 10, and the rod head 10 is in contact with the object.
[0024] The outer wall of the rod body 9 is provided with an extension mechanism, which includes an extension rod 12. A silicone sleeve 13 is fitted on the outer wall of the extension rod 12. One end of the rod body 9 is provided with a threaded groove. A threaded head 11 is threadedly connected to the inner wall of the threaded groove. One end of the threaded head 11 is fixedly connected to one end of the extension rod 12. The extension rod 12 is fixedly connected to the rod body 9 through the threaded head 11 and the threaded groove.
[0025] Working principle: The support rod sleeve 1 is hung on the rod body 9 via the extension rod 4, flat block 5, second bolt 6, and sliding sleeve 7. The support rod sleeve 1 can be rotated to fit snugly against the rod body 9 for carrying. In use, the U-shaped support foot 3 is placed on the ground. Depending on the environment, the support height of the rod body 9 can be adjusted by rotating the support rod sleeve 1 via the extension rod 4. At the same time, the locking bolt 8 can be rotated to release the position fixation of the rod body 9, allowing the rod body 9 to slide through the sliding sleeve 7 to adjust the position of the rotation fulcrum of the rod body 9 and the position of the rod head 10. The extension rod 12 is screwed into the threaded groove through the threaded head 11 to increase the overall length of the rod body 9. Meanwhile, the silicone sleeve 13 improves the comfort of the grip, facilitates subsequent use, and increases applicability.
