Further, a track groove 11c for moving the roller c is further provided on the frame plate 11, the roller c traverses through the track groove 11c, and when the lock plate is unlocked, the roller c moves upward along the track groove 11c and pushes the lock plate 30 to turn upward around the rotation axis z.

In addition, the operation is convenient, a handle 413 can be arranged at the upper end parts of the left arm rod 410 and the right arm rod 411, and after the handle is pressed, the rotation adjustment of the left arm rod 410 and the right arm rod 411 can be realized.

When the upper ends of the left arm lever 410 and the right arm lever 411 move upward along the length direction of the avoiding groove 13a, the bolt connector 412 moves upward along the length direction of the movable groove 11b, and then the unlocking module 40 is driven to move upward, after the roller c moves upward along the track groove 11c and contacts with the corresponding contact piece 30, the contact piece 30 is pushed to overturn upward around the rotating shaft z for unlocking, until the left arm lever 410 and the right arm lever 410 move into the bayonet groove 13b respectively, the locking plate 30 is positioned in the unlocking state, the tension spring is in the deformation state, and meanwhile, the plugging module 30a of the locking plate 30 is completely separated from the locking groove 20a, so that the steering adjustment can be implemented.

After the steering is adjusted to a required angle, the upper end parts of the left arm lever 410 and the right arm lever 410 are operated to slide from the bayonet groove 13b to the avoiding groove 13a and are pressed downwards, the bolt connecting piece 412 moves downwards along the length direction of the movable groove 11b at the moment so as to drive the unlocking module 40 to move downwards, the roller c moves downwards along the track groove 11c and is gradually separated from the supporting locking plate, meanwhile, under the reset of the tension spring, the locking plate 30 turns downwards around the rotating shaft z and is inserted into the locking groove 20a and the inserting groove 10a below from the inserting module 30a until the left arm lever 410 and the right arm lever 411 are abutted against the bottom of the avoiding groove 13a, the tension spring restores to a deformed state, and the steering mechanism is positioned in a locked state at the moment.

As shown in fig. 8 to 12, the second adjusting unit T2 includes a first tilting module T21 for tilting the seat body a10 and the rotating frame 2 up and down by rotating around a horizontally disposed tilting axis f.

The seat body a10 includes upper seat body 100 and lower seat body 101, wherein the relative both sides of lower seat body 101 are rotated with the both ends of trip shaft f and are connected, and upper seat body 100 passes through the axis of rotation with the tip that lower seat body 101 is kept away from trip shaft f and is connected, and slide a11 sets up on upper seat body 100, and second regulating unit T2 still includes the second upset subassembly T22 that is used for adjusting upper seat body 100 and lower seat body 101 upset from top to bottom.

The first turning assembly t21 includes a first air spring q having two ends respectively rotatably connected to the lower base 101 and the rotating frame 2, and a first touch rod p rotatably disposed on the lower base 101 and capable of touching the pneumatic switch of the first air spring q, wherein the base a10 is turned over relative to the rotating frame 2 after the first touch rod p is operated to touch the pneumatic switch of the first air spring q.

Specifically, the turning shaft f is fixed to the upper end of the pivot s, and a connecting rod g is provided below the pivot s in parallel with the pivot s.

Two first air springs q are correspondingly arranged on two opposite sides of the lower seat body 101, wherein two ends of each first air spring q are respectively and rotatably connected with one end of the connecting rod g and the front end of the corresponding side of the lower seat body 101.

Referring to fig. 8 and 9 again, a handle W is provided at the left end of the lower seat 101, and both ends of the first air spring q and the end of the flip shaft f form a triangle.

In this example, the shape of the triangle is changed by the length of the first air spring q, so that the seat body a10 can be turned up and down to a proper angle around the turning shaft f.

First touching member p is including rotating the first feeler lever p1 that sets up on lower pedestal 101 and can conflict the pneumatic switch of two first air springs q in step, and first handle p2, wherein first handle b1 is located the below of handle W, and correspond the length direction one end that sets up at handle W, upwards hold first handle p2, make first handle p2 laminate on handle W, at this moment, first feeler lever p1 touches the pneumatic switch of first air spring q, so, along with the length change of first air spring, overturn the pedestal to suitable angle from top to bottom, then release first handle, the stable bearing structure of triangle-shaped has been formed.

The second flipping module t22 includes a second gas spring t with two ends respectively rotatably connected to the lower seat 101 and the upper seat 100, and a second touch rod d rotatably disposed on the lower seat 101 and capable of touching the pneumatic switch of the second gas spring t, wherein after the second touch rod d is operated to touch the pneumatic switch of the second gas spring t, the upper seat 100 flips up and down relative to the lower seat 101.

As for the second touch rod d, the principle and the embodiment thereof are similar to those of the first touch rod p, specifically, the second touch rod d includes a second touch rod d1 rotatably disposed on the connecting rods at the two ends of the grip W and capable of synchronously abutting against the pneumatic switches of the two second gas springs t, and a second handle d2, wherein the second handle d2 is located below the grip W and correspondingly disposed at the other end in the length direction of the grip W, and the second handle d2 is upwardly gripped so that the second handle d2 abuts against the grip W, at this time, the second touch rod d1 abuts against the pneumatic switch of the second gas spring t, so that the upper seat 100 is turned to a proper angle relative to the lower seat 101 along with the change in the length of the second gas spring t.

The third adjusting unit T3 includes a slide rail T30 extending along the length direction of the seat body a10 and matching with the slide seat a11, and a locking component T31 locking the slide seat a11 and the seat body a10 relatively.

Specifically, the slide rail t30 is disposed on the upper base 100, and the locking assembly t31 is a common locking bolt.

The present invention has been described in detail above, but the present invention is not limited to the above-described embodiments. All equivalent changes or modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
