Referring to fig. 1 and 2, the fascial gun 10 according to an embodiment of the utility model includes a handle 100, a body 200, a driving assembly 300 and a massage assembly 400, wherein the body 200 is connected to the handle 100, and the driving assembly 300 is accommodated in the handle 100. The massage assembly 400 includes a piston 410 and a massage head 420 connected to the piston 410, wherein the piston 410 is disposed in the body 200, and the massage head 420 is exposed out of the body 200. The driving assembly 300 is connected to the piston 410 to drive the piston 410 to reciprocate relative to the body 200, so that the piston 410 drives the massage head 420 to move for massage.

As shown in fig. 2 and 3, in particular, the body 200 includes a first cylinder 210, a second cylinder 220 and a connection ring 230. The first cylinder 210 is connected to the handle 100, the second cylinder 220 is in threaded connection with the first cylinder 210, and the connection ring 230 is sandwiched between the first cylinder 210 and the second cylinder 220. In other embodiments, second barrel 220 may also be connected to handle 100.

As shown in fig. 3 to 6, the first cylinder 210 further includes a threaded section 240, a mounting section 250, and a cylinder section 260, which are connected in sequence, wherein the cylinder section 260 is connected to the handle 100. The connection ring 230 is sleeved on the mounting section 250, and the outer diameter of the mounting section 250 is smaller than that of the cylinder section 260. The second barrel 220 is threadably engaged with the threaded section 240 and the second barrel 220 and barrel section 260 together clamp the attachment ring 230.

In the fascial gun 10, the installation section 250 is arranged between the threaded section 240 and the cylinder section 260, so that the installation section 250 can be tapped by exceeding the threaded section 240 during tapping, the situation that the thread length on the threaded section 240 is short due to the fact that the threaded section 240 is not tapped can be effectively avoided, and the second cylinder 220 and the threaded section 240 are stably connected. In addition, after the mounting segment 250 is tapped, the remaining mounting segment 250 can be covered by the connection ring 230, the connection ring 230 can be clamped by the first cylinder 210 and the second cylinder 220, and the rotation resistance of the second cylinder 220 can be increased, so that the problem that the second cylinder 220 is loosened relative to the threaded segment 240 under the action of vibration can be avoided, the first cylinder 210 and the second cylinder 220 can be stably connected, and the overall structural assembly stability of the fascial gun 10 can be improved.

Specifically, the outer diameters of the threaded section 240, the mounting section 250, and the cylinder section 260 sequentially increase to step the first cylinder 210. One end of the connection ring 230 abuts against the end surface of the barrel section 260 and the other end abuts against the second barrel 220 screwed with the threaded section 240.

The width of the attachment ring 230 is greater than the width of the mounting section 250 so that the second barrel 220 can be screwed into the threaded section 240 to clamp the attachment ring 230 together with the end surface of the barrel section 260. Specifically, the width of the connection ring 230 protruding the mounting section 250 is 0.1-0.7 mm.

In one embodiment, the end of attachment ring 230 distal to barrel section 260 is a predetermined distance 270 from the end of threaded segment 240 distal to barrel section 260, the predetermined distance 270 being greater than or equal to 2.5 mm. It can be understood that the length of the threaded section 240 beyond the connection ring 230 is the predetermined distance 270, and when the predetermined distance 270 is greater than or equal to 2.5mm, the threaded length capable of being screwed with the internal thread of the second cylinder 220 is longer, so that the second cylinder 220 and the threaded section 240 can be stably connected.

In one embodiment, the width of attachment ring 230 is greater than 1.5 mm. It can be understood that when the width of the connection ring 230 is small, the processing precision of the connection ring 230 is high, and once the processing error of the connection ring 230 occurs, the second cylinder 220 and the cylinder section 260 are liable to fail to clamp the connection ring 230.

Specifically, the connection ring 230 is in clearance fit with the installation section 250, so that the connection ring 230 can be easily sleeved on the installation section 250, and the assembly convenience of the connection ring 230 and the installation section 250 is improved. In other embodiments, the attachment ring 230 is over-fitted to the mounting section 250 such that the attachment ring 230 is stably sleeved on the mounting section 250.

Specifically, in the present embodiment, the connection ring 230 has an inner annular surface 231, a first end surface 232 and a second end surface 233, the inner annular surface 231 is an inner wall surface of the connection ring 230 facing the mounting section 250, the first end surface 232 is an end surface abutting against the cylinder section 260, and the second end surface 233 is an end surface abutting against the second cylinder 220.

Further, the mounting section 250 has an outer annular surface 251, and the diameter of the inner annular surface 231 of the connection ring 230 is larger than the diameter of the outer annular surface 251 of the mounting section 250, thereby ensuring a clearance fit between the connection ring 230 and the mounting section 250.

In one embodiment, one of the inner annular surface 231 and the outer annular surface 251 is formed with a limiting groove (not shown), and the other is formed with a limiting protrusion (not shown), and the limiting groove and the limiting protrusion cooperate to limit the connection ring 230 to rotate relative to the mounting section 250 along the circumferential direction, so as to achieve stable mounting of the connection ring 230 on the mounting section 250.

Specifically, the attachment ring 230 has a first inclined surface 234, and the first inclined surface 234 extends from the inner annular surface 231 to the first end surface 232 in a diverging conical surface in a direction toward the barrel section 260. It will be appreciated that the end of the attachment ring 230 adjacent the barrel section 260 is flared with an increasing opening. In this manner, the first inclined surface 234 may serve as a guide for facilitating the installation of the connection ring 230 when the connection ring 230 is fitted into the installation section 250.

Further, the mounting section 250 has a second ramp 252 at its junction with the barrel section 260, and the first ramp 234 is capable of mating with the second ramp 252. By arranging the first inclined surface 234 on the connection ring 230 and the second inclined surface 252 attached to the first inclined surface 234, the contact area between the connection ring 230 and the first barrel 210 can be increased, the connection ring 230 is prevented from moving relative to the mounting section 250 in the radial direction, and the connection ring 230 is further ensured to stably abut against the barrel section 260.

Specifically, at least a portion of the second end surface 233 of the connection ring 230 is tapered to make the end of the connection ring 230 convex. The second cylinder 220 has a third end surface 221, and the shape of the third end surface 221 is matched with the shape of the second end surface 233 and is attached to the second end surface 233.

It will be appreciated that in the embodiment shown in fig. 4, only a portion of the second end surface 233 is tapered. Specifically, the second end surface 233 is divided into a first abutting surface 235 and a second abutting surface 236, wherein the first abutting surface 235 is an inclined conical surface, and the first abutting surface 235 is connected to the inner annular surface 231. The third end surface 221 is divided into a third abutting surface 222 and a fourth abutting surface 223, the third abutting surface 222 is attached to the first abutting surface 235, and the fourth abutting surface 223 is attached to the second abutting surface 236, so that the third abutting surface 222 is an inclined conical surface adapted to the first abutting surface 235. With such an arrangement, not only the contact area between the second end surface 233 and the third end surface 221 can be increased to ensure the stable abutment of the connection ring 230 and the second cylinder 220, but also the third abutment surface 222 can apply a dual pressing force along the radial direction and the axial direction to the first abutment surface 235 when the second cylinder 220 is in threaded connection with the threaded section 240 and the connection ring 230 is clamped, so as to ensure that the connection ring 230 is stably clamped by the second cylinder 220 and the cylinder section 260, and prevent the connection ring 230 from loosening. In addition, the third abutting surface 222 is in a flared shape, and can play a guiding role in the process of matching the second cylinder 220 with the threaded section 240, so that the second cylinder 220 and the threaded section 240 can be conveniently assembled and connected.

In another embodiment, all of the second end surfaces 233 may be inclined tapered surfaces, and in this case, all of the third end surfaces 221 may be inclined tapered surfaces, and similar effects can be achieved by complete contact between the second end surfaces 233 and the third end surfaces 221.

In one embodiment, an end of the threaded section 240 away from the mounting section 250 has a tapered outer diameter gradually decreasing in a direction away from the mounting section 250. As shown in fig. 4, it can be understood that the end of the threaded section 240 has a third inclined surface 241, and the third inclined surface 241 is a tapered surface and gradually decreases in diameter in a direction away from the mounting section 250, so that the end of the threaded section 240 is tapered. In the process of matching the second cylinder 220 with the threaded section 240, the third inclined surface 241 can play a role in guiding, so that the second cylinder 220 and the threaded section 240 can be conveniently assembled and connected.

Specifically, the connection ring 230, the first cylinder 210, and the second cylinder 220 may be differently arranged in surface colors, i.e., one of them has a surface color different from the other two, so that a distinct boundary line may be formed, thereby facilitating identification of various portions of the main body 200 for quick disassembly. For example, the color of the surface of the connection ring 230 is different from that of the first and second barrels 210 and 220, and the color of the surface of the first and second barrels 210 and 220 is the same; or the surface colors of the three are different. It will be appreciated that the difference in surface colour that is desired can be achieved by applying pigments, by different surface treatment processes, etc.

In other embodiments, the surface textures of the connection ring 230, the first cylinder 210 and the second cylinder 220 may be arranged differently, that is, one of the three has a surface texture different from the other two, so that a distinct boundary line can be formed, thereby facilitating identification of various parts of the body 200 for quick assembly and disassembly. For example, the connecting ring 230 is made to have a different surface texture from the first and second barrels 210 and 220, and the surface texture of the first and second barrels 210 and 220 is the same; or the surface textures of the three are different. It will be appreciated that the difference in surface texture may be achieved by machining, by different surface treatment processes, etc.

Specifically, in this embodiment, the attachment ring 230, the barrel section 260 and the outer surface of the second barrel 220 are located on the same cylindrical surface. It can be understood that the connecting ring 230, the barrel section 260 and the outer wall surface of the second barrel 220 are identical in shape and size, so that the surface of the body is smooth and cannot be scratched.

Further, the connection ring 230, the barrel section 260 and the outer surface of the second barrel 220 are located on the same cylindrical surface, so that after the fuselage 200 is disassembled and assembled for a plurality of times, the smoothness of the outer surface of the fuselage 200 can still be ensured after the connection ring 230 is assembled and clamped between the second barrel 220 and the first barrel 210.

In one embodiment, the first cylinder 210 has a through hole 280, and the handle 100 also has a connecting hole (not shown) opposite to the through hole 280, wherein the connecting member can pass through the through hole 280 and the connecting hole to detachably connect the first cylinder 210 to the handle 100. Specifically, the through hole 280 extends from one end of the cylinder section 260 away from the threaded section 240 along the axial direction of the first cylinder 210 and penetrates through the threaded section 240, i.e., a through hole penetrating through two end faces of the first cylinder 210 is formed, and after the second cylinder 220 is in threaded connection with the first cylinder 210, the second cylinder 220 can cover one end of the through hole 280, so that the through hole 280 is prevented from being exposed, and the machine body 200 has a better appearance effect.

The motor 310 can rotate the cam 320, and the cam 320 can further move the link 330. The connecting rod 330 is connected to the piston 410 to drive the piston 410 to reciprocate within the body 200.

In one embodiment, the handle 100 includes a connecting section 110, a holding section 120, an upper cover 130 and a bottom cover 140, wherein one end of the connecting section 110 is connected to the holding section 120 by a screw, the other end is connected to the upper cover 130 by a screw, the body 200 is connected to the connecting section 110, and the motor 310, the cam 320 and the connecting rod 330 are limited inside the structure formed by the connecting section 110 and the upper cover 130. One end of the holding section 120 is screwed with the connecting section 110, and the other end is screwed with the bottom cover 140, and the power source 340 and the PCB 350 are defined inside the structure formed by the holding section 120 and the bottom cover 140. By designing the handle 100 as a multi-segment structure, the quick assembly and disassembly of the various portions of the drive assembly 300 inside the handle 100 can be facilitated.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
