The swing motor 1 is connected with the shell 5 through the fixed connecting piece 9 and is connected with the battery bracket 4 through the rear shock pad 3, so that the swing motor 1 can be suspended relative to the shell 5 and does not form direct contact with the shell 5, a vibration transmission path between the swing motor 1 and the shell 5 can be cut off, and the vibration energy transmission is reduced, the motor bracket 2 is connected with the end part of the shell 5 through the fixed connecting piece 9, so that the peripheral wall of the motor bracket 2 is not contacted with the inner wall of the shell 5, the vibration of the swing motor 1 can not be transmitted to the shell 5 through the peripheral wall of the motor bracket 2, the vibration transmission path of the swing motor 1 can be further cut off from the front end, and the motor is arranged on the battery bracket 4 through the rear shock pad 3, the periphery wall of back shock pad 3 does not contact with the inner wall of shell 5, consequently can not directly transmit swing motor 1's vibrations effect to shell 5 through the periphery wall, can further cut off swing motor 1's vibrations transmission route from the rear end, swing motor 1's vibrations energy only can be transmitted to shell 5 through the fixed connector 9 of front end or indirectly through the battery support 4 of rear end, utilize foretell shock-absorbing structure design, can all carry out shock attenuation processing with swing motor 1 resonance source relevant structure from front end and rear end, consequently, can reduce swing motor 1's vibrations energy transmission by a wide margin, reduce resonance energy, improve the shock attenuation effect of handle, reduce vibration noise and the sense of vibration of gripping, improve user's use experience.

In this embodiment, along the axial direction of the swing motor 1, the motor support 2, the swing motor 1, the rear cushion 3 and the battery support 4 are sequentially disposed, and the front end of the swing motor 1 is connected with the sealing cover 7 in the axial direction through the motor support 2, the rear end of the swing motor 1 is connected with the battery support 4 in the axial direction through the rear cushion 3, and a preset gap is formed between the outer peripheral walls of the swing motor 1, the motor support 2 and the rear cushion 3, which extend in the circumferential direction around the output shaft of the swing motor 1, and the inner wall of the housing 5, so that the swing motor 1, the motor support 2 and the rear cushion 3 are not in contact with the inner wall of the housing 5 in the circumferential direction, and are mounted only through the axial structure, and the vibration transmission paths are only axially transmitted and are dispersed to the front and rear ends, so the vibration transmission paths are few, and meanwhile, separation of the vibration absorption structure can be realized, and the vibration absorption effect is effectively improved, and vibration transmission is reduced.

The swing motor 1 is, for example, a sonic motor. The fixed connection 9 is for example a threaded connection.

In one embodiment, the end of the motor bracket 2 away from the swing motor 1 is provided with a connecting column 10, and the connecting hole 6 is arranged on the connecting column 10.

In this embodiment, the end of the motor bracket 2 is provided with the connecting hole 6, so that the fixed connection with the fixed connecting piece 9 can be conveniently realized. Through setting up spliced pole 10, can increase motor support 2's overall axial length on the basis of adopting less material, conveniently realize and fixed connection 9 between be connected because motor support 2 passes through to realize the multiple spot contact between spliced pole 10 and the shell 5, rather than form large tracts of land contact through the terminal surface, consequently can further reduce the area of contact between motor support 2 and the shell 5, reduce the vibrations energy transfer.

The quantity of spliced pole 10 is at least two to along the circumference evenly distributed of closing cap 7, can improve the homogeneity of the distribution of the atress between motor support 2 and the shell 5, improve structural design's rationality. In the present embodiment, the number of the connecting columns 10 is four.

In one embodiment, the handle further comprises a front shock pad 11, a mounting boss 12 is arranged in the middle of the motor bracket 2, the number of the connecting columns 10 is multiple, the mounting boss 12 is located in the middle of the connecting columns 10, the front shock pad 11 is of an integral structure, and the front shock pad 11 is sleeved outside the mounting boss 12 and the connecting column 10.

The motor bracket 2 has a hardness greater than that of the front and rear cushion pads 11 and 3. In one embodiment, the motor bracket 2 is hard rubber and the front and rear shock pads 11, 3 are soft rubber.

In this embodiment, in order to ensure the effect of the motor bracket 2 on mounting and fixing the swing motor 1, and reduce the vibration amplitude of the swing motor 1 in the working process, the motor bracket 2 needs to have good hardness, so as to form a constraint on the vibration of the swing motor 1, and then, because the hardness of the motor bracket 2 is relatively high, although the limitation on the vibration of the swing motor 1 can be formed to a certain extent, at the same time, after the vibration of the swing motor 1 is transmitted to the motor bracket 2, the influence of the hardness of the motor bracket 2 is received, the damping function of the motor bracket 2 is relatively poor, if the motor bracket 2 contacts with the housing 5 in the vibration process, the transmission efficiency of the vibration is also higher, and the adverse effect on the damping performance of the handle can be generated.

Through setting up preceding shock pad 11, shock pad 11 forms the shock attenuation protection in motor support 2's periphery before can utilizing, thereby when motor support 2 receives the vibrations influence of swing motor 1 to take place vibrations, the periphery wall can not directly form direct contact with shell 5, but form the contact between the internal perisporium through preceding shock pad 11 and shell 5, because preceding shock pad 11 is soft rubber, consequently, it is better to the absorptivity of shock energy, can absorb the shock energy that swing motor 1 transmitted to motor support 2 more high-efficiently, motor support 2 can be weakened to the shock energy of shell 5 through preceding shock pad 11 transmission at the vibrations in-process by a wide margin, consequently, can effectively reduce swing motor 1 and follow the energy that the circumferential direction probably transmitted to shell 5 at the vibrations in-process, and then weaken the handle and grip the sense of vibration of in-process, improve user's use experience.
