The inner side of the horn head 301 is provided with a slot. The slot of the horn head 301 is provided with an inner chamfer 302. The root of the inner chamfer 302 is arranged in an enlarged shape. The horn head 301 arranged at the bottom of the main rod assembly 1 is provided with a slot to form a horn shape, which can lift nails and other objects. The slot of the horn head 301 is provided with an inner chamfer 302, so that the nails and other objects can be better clamped and fixed.

[0035] In this embodiment of the disclosure, such as Figure 1 Figure 2 As shown, the top block 401 of the pickaxe assembly 4 is located at the top of the main rod assembly 1. A flat pickaxe head 402 and a pointed pickaxe head 403 are mounted on the top block 401, with the pointed pickaxe head 403 and the flat pickaxe head 402 at right angles to each other. By mounting the flat pickaxe head 402 and the pointed pickaxe head 403 on the top block 401 at right angles, the flat pickaxe head 402 and the pointed pickaxe head 403 can be easily used together. The flat pickaxe head 402 and the pointed pickaxe head 403 can be used in different situations, thus increasing their versatility. The bottom of both the flat pickaxe head 402 and the pointed pickaxe head 403 is... The top block 401 has reinforcing ribs 405 and hammer blocks 404 on opposite sides of the flat pick 402 and pointed pick 403. Hammer blocks 404 are first placed on opposite sides of the flat pick 402 and pointed pick 403 on the top block 401 to facilitate insertion into areas where insertion is difficult. After aligning the flat pick 402 and pointed pick 403, the hammer blocks 404 are directly struck to push them in. Reinforcing ribs 405 are placed at the bottom of the flat pick 402 and pointed pick 403 to provide greater stability.

[0036] The working principle of this embodiment is as follows: When using the tool, the ram's horn part 3 can be used to directly pry up nails or other objects. For breaking or crushing, the pointed pick 403 is used to strike the object directly with its tip. If further force is needed, the pointed pick 403 can be pushed deeper by striking the hammer head block 404 again. When prying objects directly, the flat part of the flat pick 402 is used to wedge into the gap. Similarly, the hammer head block 404 can be struck to increase the depth. When the tool cannot apply more prying force, the fastening component 2 is used to extend the main rod assembly 1. Then, the fastening component 2 is tightened to fix the main rod assembly 1, thus applying pressure to the extended main rod assembly 1 for use.

[0037] The following points should be noted in this article:

[0038] 1. The accompanying drawings of the embodiments disclosed herein only relate to the structures involved in the embodiments disclosed herein; other structures can be referred to in general design.

[0039] 2. Where there is no conflict, the embodiments of this disclosure and the features in the embodiments can be combined with each other to obtain new embodiments.

[0040] The above merely describes specific embodiments of the present disclosure, but the protection scope of the present disclosure is not limited thereto, and any person skilled in the art can easily think of changes or replacements within the technical scope disclosed by the present disclosure, which should be covered within the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be subject to the protection scope of the claims.
