Technical Field

[0001] The utility model relates to the technical field of detachable alloy pickaxe heads, in particular to a detachable alloy pickaxe head. Background Art

[0002] The electric pick is a double-insulated handheld power tool powered by a single-phase series-excited motor. It is safe, reliable, efficient and easy to operate. It is widely used in pipeline laying, machinery installation, water supply and drainage facility construction, interior decoration, port facility construction and other construction projects. It is suitable for crushing, leveling, excavating, grooving and cutting concrete, masonry structures and asphalt pavements with a pick or other appropriate accessories such as a chisel and a shovel.

[0003] Since the tip of the electric pick is made of alloy, once it is damaged during use, it needs to be replaced as a whole, and the replacement of the whole causes a significant increase in cost.

[0004] Therefore, a detachable alloy pick head is needed to improve the above problems. Utility Model Content

[0012] As a preferred solution of the utility model, a fixed magnet is arranged at the bottom of the placement tube, and the auxiliary rod is made of iron.

[0013] As a preferred solution of the utility model, the fixing block is arranged in a "cone" shaped structure, and the diameter of the rear end of the fixing block is larger than the diameter of the connecting column, the diameter of the front end of the fixing block is the same as the diameter of the fixing rod, and the fixing block is arranged on the back side of the connecting sleeve.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] In the utility model, a fixing assembly and a connecting sleeve are provided on the detachable alloy pick head, the connecting sleeve is sleeved on the alloy pick head, and the fixing rod is passed through the fixing through hole. When the fixing block passes through the rear side of the connecting sleeve, the fixing block moves downward under the action of gravity, so that the fixing rod can be limited and the fixing rod is fixed in the fixing through hole. The auxiliary block can drive the auxiliary rod to move to the outside of the placement tube, and the fixing block can be driven to move upward by the auxiliary rod. When the center of the fixing block and the center of the fixing rod are on the same horizontal line, the fixing rod is moved outward. When the fixing rod moves to the outside of the fixing through hole, the connecting sleeve can be separated from the alloy pick head. Therefore, when the alloy pick head is damaged, it can be replaced individually without replacing all of it, thereby saving costs. The overall device has a simple structure, is easy to operate and has higher practicality. BRIEF DESCRIPTION OF THE DRAWINGS
