Description

Multi-handle fascia gun

Technical Field

The utility model belongs to the massage equipment field, concretely relates to many handles manadesma rifle.

Background

Fascia guns, also known as deep myofascial impacters, are a soft tissue massage tool that relaxes the body's soft tissues by high frequency impact. The existing fascia gun drives a massage head to do reciprocating linear motion through a massage driving mechanism, the massage head is contacted with a human body, and high-frequency vibration is generated to act on a muscle deep layer, so that the fascia gun has the effects of reducing local tissue tension, relieving pain, promoting blood circulation and the like.

In order to massage different parts of the body conveniently, people develop a fascia gun with a massage head capable of rotating a certain angle, which generally comprises a handle and a steering head rotatably arranged at the upper end of the handle. However, after the massage head is rotated to a non-initial angle, the axis of the reciprocating motion of the massage head is difficult to coincide with the gravity center of the fascia gun and is relatively vertical to the holding direction of the handle, so that the force application of a user is not facilitated, and the impact depth to the muscle is difficult to maintain, therefore, the multi-handle fascia gun with a plurality of handles with different angles is developed on the basis. For example: chinese patent application publication No. CN111989076A discloses an impact massage apparatus including a housing, a power source, a motor positioned in the housing, a switch for activating the motor, and a push rod assembly operatively connected to the motor and configured to reciprocate in response to activation of the motor. The housing includes first, second, and third stems that cooperate to define a stem opening, wherein the first stem defines a first axis, the second stem defines a second axis, and the third stem defines a third axis, and wherein the first, second, and third axes cooperate to form a triangle. All handles are long enough so that they are configured to enable an individual to grasp that particular handle to utilize the device.

Although the user can use the above massage device by holding different handles on different body parts and from different angles, thereby abutting against body parts such as the back where massage may not be achieved without using three handles to achieve better massage effect; but above-mentioned massage device's three handle encloses into the triangle-shaped structure, thereby if guarantee that the user palm stretches into triangle-shaped's inner chamber completely and hold the handle, or the handle need have sufficient length, or reserve enough big space in the acute angle department of triangle-shaped inner chamber, however whichever kind of mode above adopting all can lead to massage device's main part too big, not only increased the cost of manufacture and the use degree of difficulty, and the major structure is not compact, the triangle-shaped inner chamber is close to the space waste of base department, the user grips not tightly when the vibration is great, massage effect and user experience have been reduced.
