The invention relates to an anti-slip type forehead temperature gun with high measurement accuracy, including a main body, a detection head, and a handle, and further including an anti-slip mechanismand two positioning mechanisms. The positioning mechanism includes a driving component, a guide rail, a moving rod, a positioning bar, a sliding block, two first springs, and two driving blocks, the anti-slip mechanism includes an air collecting tube, a support rod, an electric generator, a fan blade, and at least two reinforcing components, the reinforcing component includes a limited post, a cylindrical notch, a second spring, and an air delivery tube, and the driving component includes a motor and a screw rod. In the anti-slip type forehead temperature gun with high measurement accuracy, adistance between the forehead temperature gun and a human body can be controlled by using the positioning mechanism, thereby improving measurement accuracy of the forehead temperature gun, and friction between the forehead temperature gun and a user palm can be increased by using the anti-slip mechanism, thereby reducing a probability of the forehead temperature gun slipping down and reducing a probability of damage of the forehead temperature gun.
