Abstract
The invention relates to a multifunctional metal shovel which comprises a shovel handle and a shovel head. A rotating platform with a center shaft hole is arranged at one end of the shovel handle. A rotating block is arranged on the shovel head and provided with shaft holes. The same fastener penetrates the center shaft hole and the shaft holes. A closing hole, a hand shield hole, a spear hook hole, a hoe hole and a shovel head hole are sequentially formed in the rotating platform around the center shaft hole in the same rotating direction, and the center of the closing hole, the center of the hand shield hole, the center of the spear hook hole, the center of the hoe hole and the center of the shovel head hole are all arranged on the same circle. The rotating block comprises rotating parts, the two sides of the shaft hole in one rotating part are provided with a pre-tightening device and a fixing device correspondingly, and the two ends of a connecting part are connected with the rotating parts and the shovel head correspondingly. The multifunctional metal shovel has the following beneficial effects that the pre-tightening device is arranged on the corresponding rotating part, when modes are switched, pre-fixing is firstly achieved, then a fastening bolt is used for fixing, the modes are switched accurately, and the situation that the hand is pinched due to too fast switching is avoided; the hand shield hole is formed, and therefore the hand of a user can stretch into the part between the shovel head and the shovel handle; a large round hole is formed in the rotating platform, so that a climbing rope, a hemp rope and other rope tools penetrate the large round hole to be knotted, and the rope tools slide down from the shovel handle; a lengthened rod is arranged in the shovel handle, and human engineering is met; and the inner walls of the two sides of a trimming groove are mirror images, and the shearing effect is good.
Description
Technical field
The present invention relates to rescue tool, be specifically related to a kind of multi-function metal shovel.
Background technology
In rescue industry, a multi-functional instrument plays key effect for rescue and relief work, and traditional rescues
Helping instrument heavy, assembly is various, and this product mainly solves scoop difference in functionality rapid translating, and shovel head is replaceable
