Description

Technical Field

[0001] The utility model relates to the field of pickaxes, in particular to a combined pickaxe. Background Art

[0002] A pickaxe is a tool used in mining and construction projects, mainly for breaking rocks or concrete. It is usually used in conjunction with a pickaxe (also known as a pneumatic hammer or rock drill). The design of the pickaxe enables it to withstand high impact forces and wear, so it is usually made of high-hardness and wear-resistant materials such as alloy steel or tungsten steel.

[0003] When digging a hoe pit, a pickaxe is needed, and a traditional pickaxe is used on the pickaxe. This kind of pickaxe has a single function. When used in frozen soil and relatively hard soil, the bit is not easy to pull out and the amount of soil unearthed is not much, resulting in low work efficiency. Content of the Utility Model

[0004] The purpose of the utility model is to solve the shortcoming of the single function of the pickaxe in the prior art, and to propose a combined pickaxe.

[0005] In order to solve the problems existing in the prior art, the utility model adopts the following technical scheme:

[0006] A combined pickaxe, comprising a round rod, a bit and a spade. A round block is fixedly arranged on the round rod. A replacement component and a fastening component are arranged on the round rod, the bit and the spade. The replacement component includes a first thread, which is opened at the lower end of the round rod. Thread grooves are opened in both the bit and the spade. An inner groove is opened in the round block. Second threads are opened at the upper ends of both the bit and the spade. The fastening component includes a pair of round grooves, which are both opened in the round block. Hexagon socket head cap screws are both movably arranged in the round grooves. A pair of screw holes are opened in the round block. A pair of screw grooves are opened at the upper ends of both the bit and the spade. The hexagon socket head cap screws are both threadedly connected with the screw holes and the screw grooves.

[0007] Preferably, the replacement component and the fastening component are independent of each other.

[0008] Preferably, the first thread is adapted to the thread groove, and the second thread is adapted to the inner groove.

[0009] Preferably, the round rod, the round block and the bit are made of carbon steel.

[0010] Preferably, the spade is made of high manganese steel.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. In the present utility model, the bit and the spade are both connected to the round rod by threads. The lower end of the round rod is screwed into the bit or the spade, and the bit can be quickly replaced according to the geological conditions to improve work efficiency.

[0013] 2. In the present utility model, the hexagon socket head screw is inserted into the round groove, and then the hexagon socket head screw is screwed into the screw hole and the screw groove to complete the fixation of the bit or the spade. The fastening assembly has a simple structure.

[0014] 3. In the present utility model, the materials used in the device are inexpensive and the economy is high. BRIEF DESCRIPTION OF THE DRAWINGS
