Problems solved by technology

[0002] At present, the crowbar that people use to pry heavy objects is a straight rod. When using it, you need to find a support point first, and use human power to pry it. Often the fulcrum is not fixed and easy to roll to affect the effect, and then use the human body to add force. , the weight of the heavy objects to be moved is limited, and it is laborious and tiring, and it is very likely to cause injuries. This traditional crowbar should be reformed and innovated in order to liberate productivity

Description

technical field [0001] The invention relates to a screw lever type mechanical crowbar which has a fulcrum and uses a screw rod to force a heavy object. Background technique [0002] At present, the crowbar that people use to pry heavy objects is a straight rod. When using it, you need to find a support point first, and use human power to pry it. Often the fulcrum is not fixed and easy to roll to affect the effect, and then use the human body to add force. , The weight of the heavy objects to be moved is limited, and it is laborious and tiring, and it is very likely to cause injuries. This traditional crowbar should be reformed and innovated in order to liberate productivity. Contents of the invention [0003] In order to solve the above-mentioned problems, the present invention provides a screw-lever mechanical crowbar. The screw-lever mechanical crowbar is strong in lifting heavy objects, saves time and effort, and is safe and reliable. [0004] The object of the present...
