Specific embodiment

As shown in figure 1, a kind of de- hat device, it includes retained part and handle 7, and the cunning for generating impact force is equipped on handle 8 device of block；

In preferred scheme such as Fig. 2, the bottom of handle 7 is connect by slide bar 15 with handle tail 9, and sliding block 8 is slidably It is mounted on slide bar 15.

In preferred scheme such as Fig. 2, it is equipped with electromagnet in the bottom of handle 7 and/or handle tail 9, the sliding block 8 is set There is permanent magnet 81.Sliding block 8 is driven to realize the automatic percussion of sliding block 8, by electromagnet to realize one-handed performance.

In preferred scheme, it is equipped with the first electromagnet YA1 in the bottom of handle 7, handle tail 9 sets the second electromagnet YA2, The sliding block 8 is equipped with permanent magnet 81；

The coil of first electromagnet YA1 and the second electromagnet YA2 around to opposite so that the electricity of the first electromagnet YA1 and second Magnetic pole after magnet YA2 is powered is opposite；

First electromagnet YA1 and the second electromagnet YA2 is electrically connected with switch commutating circuit.Thus structure is changed by switch Commutation to circuit makes the first electromagnet YA1 and the second electromagnet YA2 attract and repel the sliding block 8 with permanent magnet 81 respectively, The reciprocating motion for realizing sliding block 8, realizes automatic continuous beating effect.

In preferred scheme, in the sliding block 8, cushion 82 is equipped with close to one end of handle 7.Thus structure is realized The percussion in hat direction is only taken off, and the percussion of the other end is buffered by cushion 82, cushion 82 uses foam-rubber cushion, rubber pad, felt pan Or their combination.It is further preferred that being equipped with noise reduction ring 83 far from one end of cushion 82 in sliding block 8, noise reduction ring 83 is ring The rubber structure of shape is embedded in the end face of sliding block 8, and percussion is greatly reduced under the premise of not offsetting beating effect in noise reduction ring 83 Noise.

Preferably as shown in figure 1, the retained part is the pawl structure for clamping corona 11, can be turned at least provided with one Dynamic movable claw 1, is additionally provided with the locking mechanism for locking 1 rotational angle of movable claw.Thus structure is locked by way of clamping Determine corona, corona is avoided to be damaged by barb.It is further preferred that in retained part, such as movable claw 1 and fixed jaw 2 and corona The inner wall of contact is equipped with anti-slip material, such as silicon rubber, to further increase firm grip degree.

In preferred scheme such as Fig. 3, the movable claw 1 is rotatably connect by pin shaft 3 with handle 7, in movable claw 1 It is equipped with position limit arm 4 towards the side of handle 7, the medial surface of preferred position limit arm 4 is tapered plane or oblique arcwall face, on handle 7 Equipped with moving along handle 7, for withstanding the cambridge ring 5 of position limit arm 4, the structure of cambridge ring 5 is as shown in Figure 3, has outer tiltedly flat Face or oblique arcwall face.Thus structure is limited the corner of movable claw 1 by the axial displacement of cambridge ring 5, to ensure movable claw The reliable retention of 1 pair of corona 11.It is also used for providing enough chucking powers simultaneously.

In preferred scheme, cambridge ring 5 is threadedly coupled with handle 7；The axial direction of cambridge ring 5 is realized by rotary wedge ring 5 Displacement.

Another optional scheme is as shown in figure 1 or cambridge ring 5 is slidably connected with handle 7, in cambridge ring 5 far from movable claw 1 One end be equipped with stop nut 6, stop nut 6 is threadedly coupled with handle 7.The axis of cambridge ring 5 is realized by rotary spacing nut 6 It is locked to displacement, and by the axial position of cambridge ring 5.The program is used in this example.

In preferred scheme such as Fig. 3, the movable claw 1 is one, is equipped with fixed jaw 2 in the opposite position of movable claw 1, Fixed jaw 2 is fixedly connected with handle 7；

In another optional scheme, the movable claw 1 is two, and two movable claws 1 are positioned opposite.

In preferred scheme such as Fig. 3, equipped with air bag 13, air bag 13 passes through for the inside that the pawl structure is contacted with corona 11 Gas-guide tube 14 is connect with gas tube 10.Thus structure makes the deformation package corona of air bag 13 by being filled with high pressure gas to air bag 13 11, thereby further ensure that clamping is reliable.And the structure can also adapt to the shape of different coronas.Optionally, air bag 13 fills The medium entered uses water or sticky hydraulic oil.

In preferred scheme, the one side of air bag 13 towards corona 11 is equipped with barb toothing.Thus structure, it is swollen in air bag 13 After swollen, clamping effect can be further increased.

In preferred scheme, entire retained part is connect by dismountable mode with handle 7, to replace different clampings Part adapts to the corona 11 of different size.

By taking preferred plan as an example, when the utility model is used, first checks pipeline and connection, test air bag 13 and sliding block Whether 8 movement is reliable.Cambridge ring 5 is backed off, movable claw 1 is opened, protrudes into patient oral cavity, corona 11 is clamped, to clamping part The side divided pushes up cambridge ring 5, and with the locking of stop nut 6, cambridge ring 5 pushes position limit arm 4 to be closed movable claw 1, further Preferably, the silicon rubber of increasing friction force is equipped in the inside of 1 inside of movable claw and/or fixed jaw 2.Manual toggle is sliding at this time Block 8 taps handle tail 9, realizes de- hat, if retained part and corona 11 disengage during de- hat, after fixing again, presses The button being arranged on lower handle or on charger is inflated to air bag 13 by gas tube 10 and gas-guide tube 14, makes air bag 13 Expansion sufficiently coats corona 11.De- hat operation is realized in the above manner.Further, if it is inconvenient, as shown in Figure 4, It presses to be located on handle and starts switch K5, master chip preferably uses STM32F family chip in this example, output control signal, The successively on-off of control switch k1 and k3 and k2 and k4, so that opposite the first electromagnet YA1 and the second electromagnet YA2 of magnetic pole is not Disconnected converted magnetic pole, the sliding block 8 that driving is equipped with permanent magnet 81 tap handle tail 9 repeatedly.Control switch k1, k3 and k2, k4 are used Transistor switching circuit or thyristor switch circuit.

The above embodiments are only the optimal technical scheme of the utility model, and are not construed as the limit for the utility model System, the features in the embodiments and the embodiments of the present application in the absence of conflict, can mutual any combination.This is practical new The protection scope of type should be with the technical solution of claim record, technical characteristic in the technical solution recorded including claim Equivalents are protection scope.Equivalent replacement i.e. within this range is improved, also the protection scope of the utility model it It is interior.
