Specific implementation manner
[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.
[0020] Refer to Figures 1-3 , a new type of wear-resistant alloy pickaxe that is convenient for disassembly and assembly, including a pick body 1. A connecting rod 2 is provided at the bottom of the pick body 1. A pick head 3 is provided at the bottom of the connecting rod 2. Circular grooves 4 are fixedly opened on both the left and right sides of the inner cavity of the connecting rod 2. A circular block 5 is arranged in the inner cavity of the circular groove 4. Insert rods 6 are fixedly installed on the opposite sides of the circular block 5. Pull blocks 7 are fixedly installed on the opposite sides of the circular block 5. Rectangular grooves 8 are fixedly opened on both the left and right sides of the connecting rod 2. Vertical rods 9 are fixedly connected to the top and bottom of the inner cavity of the rectangular groove 8. A rectangular block 10 is movably sleeved on the outer side of the vertical rod 9. A sleeve 11 is fixedly connected to the opposite side of the rectangular block 10. Support rods 17 are fixedly installed on both the left and right sides of the pick body 1. Grips 18 are arranged on the opposite sides of the support rods 17.
[0021] In this embodiment, the top of the pick head 3 extends into the inside of the connecting rod 2. The opposite sides of the insert rod 6 penetrate through the connecting rod 2 and extend into the inside of the pick head 3. Cross bars 14 are fixedly connected to the top and bottom of both the left and right sides of the inner cavity of the circular groove 4. The outer side of the cross bar 14 is in sliding contact with the inner cavity of the circular block 5. First springs 15 are fixedly connected to the opposite sides of the circular block 5. The opposite sides of the first spring 15 are fixedly connected to the inner wall of the circular groove 4. The first spring 15 is sleeved on the outer side of the pull block 7. The sleeve 11 is sleeved on the outer side of the connecting rod 2. Limiting rods 12 are fixedly installed on both the left and right sides of the bottom of the sleeve 11. The bottom of the limiting rod 12 penetrates through the pull block 7. A second spring 16 is fixedly installed on the top of the rectangular block 10. The top of the second spring 16 is fixedly connected to the top of the inner cavity of the rectangular groove 8. The second spring 16 is sleeved on the outer side of the vertical rod 9. By means of the limiting rod 12, the pull block 7 can be limited, and the pick head 3 has a double-limiting effect.
[0022] In this embodiment, the outer sides of the support rods 17 extend into the interior of the handle 18. The outer sides of the support rods 17 are threadedly connected to the inner wall of the handle 18. An anti-slip pad 19 is fixedly inlaid on the outer side of the handle 18. The top of the connecting rod 2 is fixedly connected to the bottom of the pick body 1. A pull ring 13 is fixedly installed on the outer sides of the pull blocks 7 away from each other. A connecting band 20 is fixedly installed on the top of the pick body 1. Through the anti-slip pad 19, the friction between the hands of the staff and the handle 18 is increased, and the use stability of the staff is improved.
[0023] In this embodiment, during use, by holding the sleeve 11 and moving it upward, the sleeve 11 drives the rectangular block 10 and the limiting rod 12 to move upward. When the rectangular block 10 moves upward, it will compress the second spring 16. When the bottom of the limiting rod 12 is far away from the pull block 7, the pull rings 13 on the left and right sides are respectively pulled to move away from each other. The pull rings 13 drive the pull blocks 7 to move away from each other. The pull blocks 7 drive the circular blocks 5 to move away from each other, and at the same time compress the first spring 15. The circular blocks 5 drive the insertion rods 6 to move away from each other, so that the insertion rods 6 are away from the pick head 3. Then, the pick head 3 is moved downward, and the pick head 3 can be quickly replaced, avoiding the need to replace the pick body 1, reducing the use cost. By rotating the left and right handles 18 clockwise and counterclockwise respectively, and through the cooperation of screwing with the support rods 17, the handles 18 will be driven to move away from each other, and the length of the handles 18 can be adjusted, which is convenient for different staff to hold, and improves the use convenience of the staff.
