the working surface 24 is provided with a rotary gear 10 coaxially fixed with the ratchet wheel rotating shaft 8, a moving plate 9 in sliding fit with the working plate 21, a left rotary shaft 19 and a right rotary shaft 20 which are symmetrically arranged along the moving plate 9 and are vertical to the working surface 24, a left jaw 17 and a left jaw gear 15 which are symmetrically arranged along the moving plate 9, a jaw 18, and a left jaw gear 15 and a right jaw gear 16 which are symmetrically arranged along the moving plate 9, wherein the left jaw 17 is fixedly connected with the left jaw gear 15, the right jaw 18 is fixedly connected with the right jaw gear 16, the left jaw gear 15 is in rotating fit with the working plate 21 through the left rotary shaft 19, and the right jaw gear 16 is in rotating fit with the working plate 21 through; a moving rack 12 meshed with the rotary gear 10 and a moving groove 11 limiting the sliding range of the ratchet wheel rotating shaft 8 are arranged on the moving plate 9 along the sliding direction, and a left rack 13 meshed with a left jaw gear 15 and a right rack 14 meshed with a right jaw gear 16 are arranged on two sides of the moving plate 9 along the sliding direction;
the shell 22 is provided with a claw action groove 26 for the claws (17,18) to move at the positions corresponding to the claws (17,18), the shell 22 is provided with an operation panel 25 at one side close to the transmission surface 23, the operation panel 25 is provided with a claw lock hole door 27 at the position corresponding to the locking mechanism, a handle hole is provided at the position corresponding to the ratchet wheel rotating shaft 8, and the handle 7 passes through the handle hole and is coaxially and fixedly connected with the ratchet wheel rotating shaft 8.
The working principle is as follows: in use, the bottom surface of the portable vehicle locking device shell 22 is placed on the automobile tire, and the operation panel 25 is placed to face itself. The pawl lock hole door 27 is opened, a key is inserted into the pawl lock hole 6, when the key enters the pawl lock hole 6, the front end of the key contacts the lock hole end of the L-shaped lock hole rod and pushes the lock hole end to move forward into the pawl lock hole 6, then the lock hole spring is compressed, the lock hole end rotates inwards to drive the limiting end at the other end to rotate along with the limiting end to be separated from the limiting groove, the locking of the pawl main shaft 5 is released, and the pawl lock hole 6 is controlled to rotate rightwards to enable the pawl 4 to be separated from the meshing state with the ratchet 1; the handle 7 is rotated anticlockwise, the ratchet wheel rotating shaft 8 coaxially and fixedly connected with the handle 7 rotates anticlockwise to drive the ratchet wheel 1 to rotate anticlockwise and the rotary gear 10 to rotate clockwise, so that the rotary gear 10 moves upwards on the moving rack 12 meshed with the rotary gear, at the moment, the ratchet wheel rotating shaft 8 moves upwards in the moving groove 11 on the moving plate 9, and finally, the moving plate 9 moves downwards relative to the working surface 24 of the working plate 21; meanwhile, due to the relative downward movement of the moving plate 9, the left claw gear 15 meshed with the left rack 13 rotates clockwise around the left rotating shaft 19, the right claw gear 16 meshed with the right rack 14 rotates anticlockwise around the right rotating shaft 20, so that the left claw 17 and the right claw 18 respectively connected with the left rotating shaft 19 and the right rotating shaft 20 are folded upwards along with the rotation, and the left claw 17 and the right claw 18 are folded from the claw action groove 26 to be in a locking state that the left claw 17 and the right claw 18 are tightly pressed on the vehicle body and the bottom of the shell 22 tightly presses a tire.
At the moment, the pawl main shaft 5 rotates to drive the pawl 4 to be meshed with the ratchet 1 by controlling the pawl locking hole 6 to rotate left through the key, the key is pulled out, the locking hole spring is popped out outwards in the pawl locking hole 6 to push the locking hole end of the L-shaped locking hole rod connected with the pawl main shaft to rotate outwards, the limiting end at the other end rotates along with the pawl main shaft to enter the limiting groove to be limited by the limiting groove, and therefore the pawl 4 can only swing around the pawl main shaft 5 within a small range by realizing the locking of the pawl main shaft 5. When the handle 7 rotates clockwise, the pawl 4 prevents the ratchet 1 from rotating clockwise, and the vehicle locking device is still in a locked state; when the handle 7 rotates anticlockwise, the ratchet wheel 1 and the ratchet wheel rotating shaft 8 rotate anticlockwise along with the rotation, the pawl 4 swings around the pawl main shaft 5 in a small range under the action of the spring 3, the pawl 4 slides on the tooth back of the ratchet wheel 1, and the anticlockwise rotation of the handle 7 enables the vehicle locking device to be locked between a tire and a vehicle body more tightly. When the vehicle locking device is in a locked state, if the vehicle is started, the rotation of the tire drives the vehicle locking device to rotate, and the left claw 17 and the right claw 18 damage the vehicle body of the vehicle. The vehicle body is released only when the locking of the pawl main shaft 5 is released by a key, the pawl lock hole 6 is controlled to rotate rightwards, the pawl 4 is disengaged from the ratchet wheel 1, the handle 7 is rotated clockwise, the left claw 17 rotates anticlockwise around the left rotating shaft 19, the right claw 18 rotates clockwise around the right rotating shaft 20, and the left claw 17 and the right claw 18 rotate clockwise. During the operation, the vehicle locking device is not required to be placed right above the wheels as much as possible when placed, so that a vehicle owner is prevented from taking out the vehicle locking device by using a jack; the automobile body can be slightly laterally separated from the right upper side, and the automobile owner can damage the automobile body by using the jack.
