a power transmission mechanism 50 is further arranged in the housing 6, and the power transmission mechanism 50 is used for converting the movement of the vertical moving block 3 into the movement of the clamping plate 15.

Advantageously, the transmission mechanism 60 includes a toothed belt 42, the toothed belt 42 is fixedly disposed on an end surface of the vertical moving block 3 close to the clamping mechanism 40, the toothed belt 42 can be engaged with the gear 13 after moving towards the bottom, a movable cavity 62 is disposed in the holding rod 61, one end of the handle 8 is rotatably connected with an inner wall of the movable cavity 62, and the vertical moving block 3 is fixedly connected with the holding rod 61 through a return spring 2.

Advantageously, the bottom of the holding rod 61 is further provided with a limiting cavity 28, and the vertical moving block 3 slides in the limiting cavity 28.

Advantageously, the power transmission means 50 comprise a gear wheel 13 rotatably arranged between the inner walls of the transmission chamber 21, said gear wheel 13 being in toothed engagement with the transverse toothed belt 43, two menisci 5 being fixedly connected to the housing 6 by means of four meniscal springs 4.

Advantageously, the meniscus 5 is made of TPEE (polyester rubber) with high toughness.

Beneficially, a limiting block 38 is further disposed on a portion of the housing 6 close to the vertical moving block 3, the limiting block 38 is fixedly connected with the housing 6 through two limiting springs 27, and a pull knob 10 is fixedly disposed at one end of a plane of the limiting block 38.

Beneficially, the vertical moving block 3 is provided with limiting clamping grooves 41 at different positions near one end of the limiting block 38.

Advantageously, the handle attachment cord 1 fixedly connects the grip 61 to the bus roof handle 59.

The use method of the invention comprises the following steps:

in the initial state, the return spring 2, the limit spring 27, the meniscus spring 4, the meniscus 5, the first spring 19, and the connection spring 24 are all in the normal state.

When a passenger gets on the vehicle, the hand penetrates between the clamping plates 15 and 6 and holds the handle 8, the force transmitted to the handle 8 is transmitted to the vertical moving block 3 through the connecting rod 9 to enable the vertical moving block to move towards the bottom under the action of the vertical limiting cavity 28, the vertical moving block 8 can drive the gear 13 to rotate through the toothed belt 42 of the vertical moving block 8 while moving, the transverse moving block 25 is driven to move through the meshing of the gear 13 and the transverse moving block 25, and the transverse moving block 25 further pushes the clamping auxiliary plate 14 and the clamping plate 15 to move to clamp the wrist of the passenger.

When the gripping force of a passenger is relatively light, when the vertical moving block 3 contacts the meniscus 5, the vertical moving block 3 cannot move continuously due to the elasticity of the meniscus 5 and the meniscus spring 4, after the passenger does not apply force to the grip 8, the vertical moving block 3 can reset due to the elastic action of the return spring 2, the gear 13 is driven to rotate, the gear 13 rotates to drive the transverse block 25 to move, the transverse block 25 pulls the clamping subplate 14 and the clamping plate 15, and the clamping of the wrist of the passenger is released;

when the emergency brake happens to the bus, the passenger can subconsciously apply larger force to the handle 8 instantly, when the applied force is larger than the elastic force of the meniscus 5 and the meniscus spring 4, the vertical moving block 3 can be contacted with the limiting block 38, the limiting block 38 is pushed by the vertical moving block 3, then the initial state can be recovered by the limiting block 38 due to the resilience of the limiting spring 27, the vertical moving block 3 can be clamped, the limiting and resetting are performed, meanwhile, the associated clamping subplate 14 and the clamping plate 15 can be always in the clamping state of the wrist and cannot be loosened after the vertical moving block 3 is limited and reset, and the passenger can be prevented from receiving larger impact force and being thrown away to cause injury.

After waiting for bus even running or coming off the bus, the passenger can pull knob 10, and knob 10 drives stopper 38 and outwards removes, and after stopper 38 breaks away from the spacing draw-in groove 41 of vertical movable block 3, vertical movable block 3 resumes the normal position because of reset spring 2's effect down, makes the centre gripping subplate 14 and the grip block 15 of associating give up the centre gripping of wrist department because of the removal of vertical movable block 3 simultaneously, passenger's hand alright in order to take out.

The above embodiments are merely illustrative of the technical ideas and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
