[0002] Existing fascia guns include a motor, a motor base, a cylindrical housing, and a connecting part. The motor base is used to fix the motor, and both the motor base and the motor are located inside the housing. The connecting part is located on one side of the housing and is connected to the motor base by screws passing through the housing and locking the connecting part and the housing to the housing, thus connecting the connecting part to the housing. It also includes a connecting rod, an eccentric wheel, and a piston. The output shaft of the motor is connected to the eccentric wheel, and the output shaft of the eccentric wheel is connected to one end of the connecting rod. The other end of the connecting rod is connected to the piston, which is located inside a sleeve and performs reciprocating extension and retraction motion under the drive of the motor. The fascia gun has a button connected to a circuit board, which is used to turn the motor on and off and adjust the motor speed. A battery is located on the back of the cylindrical housing to power the motor. The drawback of this fascia gun structure is that it is difficult to align the screw holes of the connecting part, the housing, and the motor base simultaneously during assembly, making assembly difficult.

[0003] Therefore, a fascia gun is needed to solve the above problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A fascia gun includes a housing, a motor, a motor base, a transmission assembly, a telescopic assembly, and a connecting part;

[0006] The motor is connected to the transmission assembly; the transmission assembly is connected to the telescopic assembly;

[0007] The outer casing has a first axis, and the connecting part has a second axis. The first and second axes are perpendicular to each other. On one side of the outer casing, there is a first opening along the second axis. The motor base has a second opening corresponding to the first opening. Inside the outer casing, there is a first fixing part and a second fixing part at the first opening, a third fixing part on the connecting part, and a fourth fixing part on the motor base at the second opening. The positions of the first fixing part and the second fixing part are different. The first fixing part of the outer casing is first connected to the fourth fixing part of the motor base through a first fixing member, and the second fixing part of the outer casing is then connected to the third fixing part of the connecting part through a second fixing member; or, the second fixing part of the outer casing is first connected to the third fixing part of the connecting part through a second fixing member, and the first fixing part of the outer casing is then connected to the fourth fixing part of the motor base through a first fixing member.

[0009] Preferably, the interior of the outer casing has a limiting block at the upper part of the first opening, and the upper part of the second opening of the motor base has a groove, with the limiting block and the groove corresponding to each other. Alternatively, the interior of the outer casing has a groove at the upper part of the first opening, and the upper part of the second opening of the motor base has a limiting block, with the limiting block and the groove corresponding to each other.

[0010] Preferably, the second fixing part is located between the first fixing parts.

[0011] Preferably, the motor includes a stator and a rotor, the rotor and the stator are connected, the stator is fixed on a motor mount, or the stator is the motor mount.

[0015] Due to the adoption of the above technical solution, the technical progress achieved by this utility model compared with the prior art is as follows: This utility model, by setting a first fixing part and a second fixing part on the outer shell, first fixes the motor base to the first fixing part of the outer shell, and then fixes the connecting part to the second fixing part of the outer shell. During assembly, the two parts are fixed separately, and the outer shell is fixed to the motor base or the connecting part, and fixed separately by different fasteners. This makes assembly easier and improves production efficiency. It avoids the problems of difficulty in alignment and easy detachment when fixing three parts simultaneously.

In some cases, when the outer shell is thicker, the mounting part becomes the inner wall of the outer shell.

[0016] This invention uses a matching limiting block and groove to position the motor base and the outer casing during assembly, preventing relative movement between them. This structure not only reduces the size of the outer casing and the fascia gun, but also solves the problem of difficult fascia gun assembly. Attached Figure Description

[0025] Please see Figure 1-3 This utility model embodiment provides a fascia gun, including a housing 1, a motor 2, a motor base 4, a transmission assembly, a telescopic assembly, and a connecting part 3;

[0026] Motor 2 is connected to transmission assembly; transmission assembly is connected to telescopic assembly. Housing 1 has a first axis, and connecting part 3 has a second axis. The first axis and the second axis are perpendicular to each other. In the direction of the second axis, housing 1 has a first opening 11 on one side, and motor base 4 has a second opening 41 corresponding to the first opening 11. Inside housing 1, a first fixing part 12 and a second fixing part 13 are provided at the first opening 11. Connecting part 3 has a third fixing part 31. Motor base 4 has a fourth fixing part 42 at the second opening 41. The positions of the first fixing part 12 and the second fixing part 13 are different. The first fixing part 12 of housing 1 is first connected to the fourth fixing part 42 of motor base 4 through a first fixing member, and the second fixing part 13 of housing 1 is then connected to the third fixing part 31 of connecting part 3 through a second fixing member; or, the second fixing part 13 of housing 1 is first connected to the fourth fixing part 42 of motor base through a second fixing member, and the first fixing part 12 of housing 1 is then connected to the third fixing part 31 of connecting part 3 through a first fixing member.

[0027] By providing a first fixing part 12 and a second fixing part 13 on the outer casing, the motor base 4 is first fixed to the first fixing part 12 of the outer casing 1, and then the connecting part 3 is fixed to the second fixing part 13 of the outer casing 1. During assembly, it is only necessary to first match the fourth fixing part 42 of the motor base 4 with the first fixing part 12 of the outer casing 1, and connect the first fixing part 12 and the fourth fixing part 42 through the first fastener, thereby fixing the outer casing 1 and the motor base 4. Then, the third fixing part 31 of the connecting part 3 is matched with the second fixing part 13 of the outer casing 1, and the third fixing part 31 and the second fixing part 13 are connected and fixed through the second fastener.

[0028] Alternatively, the connecting part 3 can be fixed to the second fixing part 13 of the outer shell 1 first, and then the motor base 4 can be fixed to the first fixing part 12 of the outer shell 1. During assembly, it is only necessary to first match the third fixing part 31 of the connecting part 3 with the second fixing part 13 of the outer shell 1, and connect the second fixing part 13 and the fourth fixing part 42 through the second fixing member, thereby connecting the outer shell 1 and the connecting part 3. Then, the fourth fixing part 41 of the motor base 4 can be matched with the first fixing part 12 of the outer shell 1, and the fourth fixing part 41 and the first fixing part 12 can be fixed by connecting the fourth fixing part 41 and the first fixing part 12 through the first fixing member.

[0029] In the axial direction of the connecting part 3, the fixing parts between the two components are easy to fix to each other, the assembly is quick, and the production efficiency is improved. The first opening 11 and the second opening 41 are correspondingly arranged, and the transmission component passes through the second opening 41 and the first opening 11 in sequence to connect with the telescopic component, and the telescopic component is connected to the massage head 5.

[0030] Furthermore, the interior of the outer casing 1 has a mounting portion 14 at the first opening 11, and the motor base 4 has a connecting surface 43 at the second opening 41. The first fixing portion 12 and the second fixing portion 13 are provided through the mounting portion 14, and the fourth fixing portion 42 is provided on the connecting surface 43. The connecting surface 43 is correspondingly provided with the mounting portion 14. The mounting portion 14 is connected to the connecting surface of the motor base 4. The mounting portion 14 increases the thickness of the outer casing 1, thereby enhancing the connection strength of the outer casing 1, improving the connection stability between the outer casing 1 and the motor base 4, and improving the connection stability between the outer casing 1 and the connecting portion 3. In some cases, when the outer casing 1 is thicker, the mounting portion 14 becomes the inner wall of the outer casing.

[0031] Specifically, the mounting part 14 has a guide surface 15, the first fixing part 12 and the second fixing part 13 pass through the guide surface 15, and the connecting surface 43 is fitted to the guide surface of the mounting part 14, so that the fourth fixing part 42 on the connecting surface 43 matches the first fixing part 12 on the guide surface 15.

[0032] The guide surface 15 guides the motor mount 4 as it is installed inside the housing 1. The connecting surface 43 of the motor mount 4 is installed along the guide surface 15. The mounting part 14 of the housing 1 is screwed to the motor mount 4 and the connecting part 3 respectively. The mounting part 14 is used to limit the position of the motor mount 4.

The limiting block 16 and the groove 44 are correspondingly arranged, and the limiting block 16 and the groove 44 are used to position and limit the motor base 4. The matching of the limiting block 16 and the groove 44 allows the motor base 4 to be installed in a certain position inside the outer shell 1. After the limiting block 16 and the groove 44 are matched, the first fixing part 12 corresponds to the third fixing part 31. This prevents the outer shell 1 and the motor base 4 from moving relative to each other, and facilitates the first fixing member to fix the first fixing part 12 to the fourth fixing part 42 on the motor base 4.

[0034] In one embodiment of this utility model, the upper part of the outer shell 1 is provided with a third opening 17, and the motor base 4 is inserted into the interior of the outer shell 1 through the third opening 17. The connecting surface 43 of the motor base 4 is assembled along the guide surface 15 of the mounting part 14 until the limiting block 16 of the outer shell 1 matches the groove 44 of the motor base 4, thus completing the assembly.

[0035] In one embodiment of this utility model, the first fixing part 12 and the second fixing part 13 are different. The second fixing part 13 is located between the first fixing parts 12. The first fixing parts 12 and the second fixing parts 13 are arranged vertically to ensure that the connecting part 3 is located in the middle of the first opening 11 and is subjected to balanced force, so that the connection is stable.

[0036] In some embodiments, the first fixing part 12 and the second fixing part 13 are arranged in different positions, with the second fixing part 13 located between the first fixing parts 12. The first fixing parts 12 and the second fixing parts 13 are distributed in a circumferential arrangement around the first opening 11, and the second fixing parts 13 are arranged on both sides of the first fixing parts 12, ensuring that the connecting part 3 is located in the middle of the first opening 11 and is subjected to balanced force, resulting in a stable connection.

[0037] In one embodiment of the present invention, the motor 2 includes a stator and a rotor. In one embodiment, the rotor is fixed on the motor base 4. In another embodiment, the stator of the motor 2 is the motor base 4. A fourth fixing part 42 is disposed on the stator. The fourth fixing part 42 of the stator is connected to the first fixing part 12 of the outer casing 1 through a first fixing member.

[0038] In one embodiment of the present invention, the outer shell 1 has a vertical cylindrical structure.

[0040] The connecting rod 51 is provided with a first bearing 54 and a second bearing 55 at both ends; the input part of the eccentric wheel 52 is connected to the rotating shaft of the motor 2, and the output part of the eccentric wheel 52 is fixedly connected to the inner ring of the second bearing 55; the outer rings of the first bearing 54 and the second bearing are fixedly mounted on the connecting rod 51; the piston 53 is movably mounted inside the connecting part, and the inner ring of the first bearing 54 is connected to the piston 53.

[0041] Furthermore, the output part of the eccentric wheel 52 is connected to the inner ring of the second bearing 55 by screws; the inner ring of the first bearing 54 is connected to the piston 53 by screws.

[0042] The output section of the eccentric wheel 52 is provided with a screw hole. After the output section of the eccentric wheel 52 passes through the inner ring of the second bearing 55, it is connected to the screw hole of the eccentric wheel 52 by a first screw 501, thus connecting the eccentric wheel 52 to the second bearing 55. The piston 53 is provided with a screw hole. The second screw 502 passes through the inner ring of the first bearing 54 and is connected to the screw hole of the piston 53, thus connecting the first bearing 54 to the piston 53.

[0043] Furthermore, the diameter of the head of the first screw 501 is larger than the diameter of the inner ring of the second bearing 55; the diameter of the head of the second screw 502 is larger than the diameter of the inner ring of the first bearing 54.

[0044] The rotation of the motor 2 shaft drives the eccentric wheel 52 to rotate, and the rotation of the eccentric wheel 52 drives the shaft to reciprocate relative to the first opening 11, which in turn drives the piston 53 to drive the massage head to reciprocate.

[0045] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
