Description

Technical Field

[0001] This utility model relates to the technical field of ice surface perforation, and in particular to an ice chisel that is easy to carry. Background Technology

[0002] An ice chisel is an ice-breaking tool with a triangular or quadrangular head, commonly used for creating openings in lake ice. However, the sharp point of an ice chisel can easily scratch others or the person carrying it, and it can also puncture things. Therefore, it's not only inconvenient to store but also quite troublesome to carry. Utility Model Content

[0003] This utility model provides a portable ice chisel, which has the technical effect of reducing the potential harm to the human body caused by the tip of the ice chisel.

[0004] A portable ice whistle employs the following technical solution:

[0005] A portable ice chisel includes a connecting rod and an ice chisel body. One end of the ice chisel body is fixed with a connector. One end of the connecting rod has a connecting hole. The connector is inserted into the connecting hole and threadedly connected to the hole wall. A second external thread is formed on the outer circumferential wall of the ice chisel body. A protective cover is fitted onto the outer side of the ice chisel body and threadedly connected to the second external thread.

[0006] Furthermore, the tip of the ice chisel body is provided with three conical surfaces, each of which has a first groove and a second groove to reduce resistance when breaking ice. The second groove is crescent-shaped.

[0007] Furthermore, a handle is fixed to the top of the connecting rod, and a support tube is fixed to the outer wall of the connecting rod. The support tube is located below the handle, and the protective cover can pass through the support tube. A locking device is provided on the support tube to fix the support tube and the protective cover.

[0008] Furthermore, the locking component includes a threaded rod and a knob. The threaded rod passes through the side wall of the support tube and is threadedly connected to the support tube. One end of the threaded rod abuts against the protective cover, and the knob is fixed on the side of the threaded rod away from the protective cover.

[0009] Furthermore, a connecting pipe is fixed to the side of the support pipe near the connecting rod. The connecting pipe is sleeved on the connecting rod. The connecting rod has multiple positioning holes arranged vertically. A fixing bolt is provided on the connecting pipe. The fixing bolt passes through the connecting pipe and is inserted into one of the positioning holes. The fixing bolt is bolted to the connecting rod.

[0010] Compared with the prior art, the present invention has the following technical effects:

[0011] When the ice chisel is not in use, cover the tip of the chisel with a protective cover to prevent it from causing damage to people or other objects. If one person's strikes are ineffective when breaking ice, two people can strike the ice chisel simultaneously to make it easier to break the ice. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. Here, the illustrative embodiments and descriptions of this utility model are used to explain the present utility model, but are not intended to limit the present utility model.

[0019] Embodiment 1 of this utility model

[0020] Reference Figure 1 and Figure 3A portable ice chisel includes an ice chisel body 1 and a connecting rod 2. The tip of the ice chisel body 1 has three conical surfaces, each with a first groove 11 and a second groove 12. The second groove 12 is located on the side of the first groove 11 away from the tip of the ice chisel body 1. The first groove 11 and the second groove 12 reduce the resistance when the ice chisel breaks ice. Due to the presence of the first groove 11 and the second groove 12, ice can break more easily along the grooves during the cutting process, thereby reducing the user's strength burden and improving ice-breaking efficiency. The second groove 12 is crescent-shaped, and multiple second grooves 12 are evenly distributed along the conical surface and gradually decrease in size.

[0021] A connector 13 is fixed to the end of the ice chisel body 1 away from the tip. The connector 13 has a first external thread 131. A connecting rod 2 has a connecting hole 21 on the side near the ice chisel body 1. The connecting hole 21 has a first internal thread 211. The connector 13 is inserted into the connecting hole 21 and threadedly connected to the connecting hole 21. A handle 22 is fixed to the end of the connecting rod 2 away from the ice chisel body 1.

[0022] The ice chisel body 1 has a second external thread 14 on its outer circumferential wall near the connector 13. A protective cover 3 is fitted onto the ice chisel body 1, and a second internal thread 31 is formed inside the protective cover 3. The protective cover 3 is threadedly connected to the ice chisel body 1. When the ice chisel is not in use, the protective cover 3 is placed on the tip of the ice chisel body 1 to prevent the tip of the ice chisel body 1 from causing injury to the human body.

[0023] A support tube 4 is fixed to the outer wall of the connecting rod 2. The support tube 4 is located below the handle 22, and its axis is parallel to the axis of the handle 22. The inner diameter of the support tube 4 is slightly larger than the outer diameter of the protective cover 3, allowing the protective cover 3 to pass through the support tube 4. A locking element 5 is provided on the support tube 4 to fix the protective cover 3 to the support tube 4. The locking element 5 includes a threaded rod 51 and a knob 52. The threaded rod 51 passes through the outer wall of the support tube 4 and is threadedly connected to the support tube. The knob 52 is fixed to the threaded rod 51, and the end of the threaded rod 51 away from the knob 52 abuts against the outer wall of the protective cover 3.

[0024] When the ice surface is thick and one person's strike is ineffective, two people can apply force to the ice chisel simultaneously. The specific operation method is as follows: pass the protective cover 3 through the support tube 4 and lock it with the locking piece 5. One person holds the handle 22 with both hands, and the other person holds the protective cover 3 with both hands opposite the ice chisel body 1. The two people apply downward force at the same time, and the ice surface can be easily broken.

[0025] Embodiment 2 of this utility model

[0026] Reference Figure 4The difference from Embodiment 1 is that a connecting pipe 6 is fixed to the side of the support pipe 4 near the connecting rod 2. The connecting pipe 6 is sleeved on the connecting rod 2 and can move up and down along the connecting rod 2. The connecting rod 2 has multiple vertically arranged positioning holes 7. A fixing bolt 61 is provided on the connecting pipe 6. The fixing bolt 61 passes through the connecting pipe 6 and is inserted into one of the positioning holes 7. The fixing bolt 61 is bolted to the connecting rod 2. The height of the connecting pipe 6 is adjustable, thereby adjusting the height of the protective cover 3 inserted into the support pipe 4, making it easier for people of different heights to hold the protective cover 3.

[0027] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model are included within the scope of protection of this utility model.
