Reciprocating-hit treatment instrument

1. A reciprocating-hit treatment instrument, comprising: a body having a reciprocating mechanism therein, wherein the body comprises a main handle portion at a lower portion, a sub-handle portion at an upper portion, a base portion extruding from one side of a connection portion between the main handle portion and the sub-handle portion on the body, a reciprocating rod with a front end extending out from the base portion while a rear end is fixedly connected with the reciprocating mechanism and configured to perform reciprocating motion in a direction of a length of the reciprocating rod under driving of the reciprocating mechanism, and a treatment ball connected with the front end of the reciprocating rod; the main handle portion, the sub-handle portion, and the base portion are integrally connected, and the main handle portion and the sub-handle portion are connected with each other to form a bar-shaped structure, the main handle portion having a greater length than the sub-handle portion;

wherein the treatment ball comprises a core of the treatment ball connected with the reciprocating rod and a treatment sleeve detachably sleeved on the core of the treatment ball and having elasticity; and

wherein the treatment sleeve comprises a face portion sleeved in a middle-front portion of the core of the treatment ball, and a wire mesh portion used for fixing the treatment sleeve on the core of the treatment ball and provided in a rear portion of the core of the treatment ball; the face portion covers at least ¾ of an area of the core of the treatment ball from the front end to the rear end, and an opening at a rear end of the wire mesh portion forms a socket fit for the core of the treatment ball.

2. The reciprocating-hit treatment instrument as claimed in claim 1 , wherein the main handle portion is provided with a fluctuating finger gripping portion on a same side as the base portion, and a bottom of the main handle portion is integrally connected with a base capable of supporting the body stably at one end.

3. The reciprocating-hit treatment instrument as claimed in claim 1 , wherein the reciprocating rod is a snap-in quick-clip connection rod inserted into the base portion.

4. The reciprocating-hit treatment instrument as claimed in claim 1 , wherein there are a plurality of replaceable treatment sleeves with different thicknesses; a plurality of bumps integrally connected with the treatment sleeve are uniformly or scatteredly distributed over an upper portion or an entire area of an outer surface of the treatment sleeve.

5. The reciprocating-hit treatment instrument as claimed in claim 1 , wherein the reciprocating rod is non-detachably traversed on the body, and the core of the treatment ball is detachably connected with the reciprocating rod, with the core of the treatment ball provided with an internally threaded hole and the front end of the reciprocating rod screwed into the internally threaded hole.

6. The reciprocating-hit treatment instrument as claimed in claim 1 , wherein an end of the wire mesh portion close to a rear end of the core of the treatment ball provided with an elastic closing wire in a form of a closed ring, and a wall surface of the front portion of the reciprocating rod is provided with a fixed structure matched with the closing wire for fixing the closing wire.

7. The reciprocating-hit treatment instrument as claimed in claim 6 , wherein the fixed structure comprises a stop tongue portion for fixing a winding start-point of the closing wire when the closing wire ( 404 ) is wound and a hooked tongue portion for fixing the wound closing wire after the winding is completed, wherein the stop tongue portion is disposed near the front end of the reciprocating rod relative to the hooked tongue portion, extending directions of the stop tongue portion and hooked tongue portion are parallel to a radial cross section of the reciprocating rod and opposite to each other, and the stop tongue portion and hooked tongue portion extend in a direction of a peripheral arc of the reciprocating rod, and a wire-winding area is formed between the stop tongue portion and hooked tongue portion.

8. The reciprocating-hit treatment instrument as claimed in claim 1 , wherein a front portion of the reciprocating rod is provided with a locking-rod mechanism which comprises a locking rod capable of reciprocating motion along a direction of the length of the reciprocating rod and a top-pressure spring embedded in the reciprocating rod, wherein a part of the locking rod is embedded in the reciprocating rod to form a guiding rod portion and a part of the locking rod exceeds a peripheral wall surface of the reciprocating rod to form a locking rod portion, and the locking rod portion is connected to a middle portion of the guiding rod portion, with a wall of an internally threaded hole of the core of the treatment ball provided with a locking groove into which the locking rod is inserted.

9. The reciprocating-hit treatment instrument as claimed in claim 1 , wherein the treatment sleeve comprises an inner surface adapted to an outer contour of the core of the treatment ball by an interference fit, and a spherical outer surface or an outer shell with an outer contour adapted to positions of a human body.

10. The reciprocating-hit treatment instrument as claimed in claim 9 , wherein the outer shell of the treatment sleeve comprises a plurality of hill-shaped projections continuous with a smooth transition.

11. The reciprocating-hit treatment instrument as claimed in claim 9 , wherein the outer shell of the treatment sleeve comprises two convex peaks arranged opposite to each other; and a massage groove used for adapting positions of the human body and formed in a middle portion by the opposite-arranged convex peaks.

12. The reciprocating-hit treatment instrument as claimed in claim 9 , wherein the outer shell of the treatment sleeve is of an elongated oval shape or an elliptical shape.

13. The reciprocating-hit treatment instrument as claimed in claim 9 , wherein the outer shell of the treatment sleeve is of a tapered shape.

14. The reciprocating-hit treatment instrument as claimed in claim 6 , wherein the wire mesh portion comprises at least two ring wires symmetrically arranged on the face portion with both end portions of each of the two ring wires integrally fixed with the face portion to form a ringlike shape, and each of the two ring wires passes around the reciprocating rod for a pulling fixation of the face portion.
