Abstract

The invention relates to a fascia gun, which comprises a shell, a telescopic driving device is arranged in the shell, the telescopic driving device comprises an outer frame, a driving motor is arranged on one side of the outer frame, an outer cylindrical surface cam is arranged on the driving motor, a telescopic sleeve is further arranged on the outer frame, a rotary sleeve is arranged at one end of the telescopic sleeve, the outer cylindrical surface cam is located in the rotary sleeve, two sliding pins arranged at an interval of 180 degrees are arranged on the outer wall of the rotary sleeve, the sliding pins extend into the rotary sleeve, and a first sliding groove and a second sliding groove are formed in the outer wall of the outer cylindrical surface cam at an interval of 180 degrees in the circumferential direction of the outer wall of the outer cylindrical surface cam. The groove depth of the first sliding groove is larger than that of the second sliding groove, the two sliding pins are in sliding fit with the first sliding groove and the second sliding groove respectively, and the length of the sliding pin of the first sliding groove penetrating into the inner wall of the rotary sleeve is larger than that of the second sliding groove. The fascia gun has the advantages of being high in bearing capacity, stable and reliable in work and short in axial size.

Description

technical field

[0001] The invention relates to the field of massagers, in particular to a fascia gun. Background technique

[0002] There are many types of existing massagers, among which the fascia gun is an essential equipment for anti-loosening massage, and its driving methods are also different. The general fascia gun uses a motor to drive the crankshaft, and the crankshaft drives the connecting rod to realize the fascia loosening. The expansion and contraction of the gun massage head makes the drive mechanism larger in the longitudinal direction, which is not conducive to the miniaturization of the product;

[0003] According to the above problems, designers have continuously optimized and improved, such as changing the traditional brushed motor to a brushless motor, greatly shortening the axial size of the motor, or changing the crankshaft and crank structure to the form of end face cam and pin head cooperation to achieve miniaturization , but the slideway of the end...
