[0002] High heels are a kind of shoes that girls love. After wearing them for a period of time, the heels will definitely wear out. Usually, you only need to replace the heels. The heels are fixed to the shoes by heel nails. Traditionally, when replacing the heels of high heels, shoe repairers must use tools to laboriously remove the heel nails. There are also nail extraction devices to extract the heel nails.

[0003] After searching, a device for pulling out nails from the heels of women's shoes with a Chinese patent announcement number of CN219088549U is found, which includes a support frame, a transmission mechanism is installed inside the support frame, a nail pulling mechanism is installed on the outside of the transmission mechanism, an auxiliary mechanism is installed on the inner bottom of the support frame, the auxiliary mechanism includes a fixed plate, a through opening and a fixed platform, a fixed plate is installed on one side of the inner bottom of the support frame, a through opening is provided inside the fixed plate, and a fixed platform is installed on the inner bottom of the support frame; the transmission mechanism includes a motor, a threaded rod and a fixed seat; by installing the auxiliary mechanism on the inner bottom of the support frame, when a person clamps the women's shoes on the outer side of the fixed platform, the fixing plate is rotated to make the heel of the women's shoe pass through the through opening inside the fixing plate, and the fixing plate can limit the heel of the women's shoe, so that there is no need for a person to lift the women's shoe, and then the heel nails of the women's shoe can be pulled out by the nail pulling mechanism.
