[0025] The locking and adjusting mechanism is composed of three groups of detachable and circular arrangements on the support seat 1 and the movable shaft 2, including a limit rod 3, a base plate 8, a baffle 10, a lead screw 11 and a second nut 12. The limit rod 3 is hinged to the movable shaft 2 through a pin 6, and the pin 6 is locked by a first nut 7. The base plate 8 is hinged to the bottom of the support seat 1 through a limit shaft 9. The lower end of the limit rod 3 is abutted against the middle groove of the base plate 8, and the baffle 10 slides in the middle groove of the base plate 8. The lead screw 11 is rotatably installed on the baffle 10 through a threaded rotating ring, and can be limited to the base plate 8 by the second nut 12. The baffle 10 is used to limit the lower end of the limit rod 3.

[0026] Before supporting the tow truck, the number of appropriate limit rods 3 can be selected according to the actual use environment, and they can be sleeved on the fixed shaft 4, and then the spring 5 can be placed on the limit rod 3, and then the movable shaft 2 can be placed in the support seat 1. At this time, the spring 5 is separated between the movable shaft 2 and the limit rod 3 to play a buffering role;

[0027] The bottom plate 8 is placed in the corresponding notch at the bottom of the support seat 1, and then the limiting shaft 9 is inserted to hinge the bottom plate 8 at the bottom of the support seat 1, and the limiting rod 3 and the movable shaft 2 are hingedly connected by the pin shaft 6, and then the first nut 7 is rotated and installed on the pin shaft 6 to limit the loosening of the pin shaft 6. At this time, the bottom of the limiting rod 3 abuts against the middle notch of the bottom plate 8. According to the height to be supported, the movable shaft 2 moves up or down in the support seat 1, and the bottom of the limiting rod 3 is at the middle notch of the bottom plate 8. After it moves to the appropriate position, the second nut 12 on the screw 11 can be rotated to make the second nut 12 abut against the end of the middle notch of the bottom plate 8, thereby limiting the movement of the baffle 10. At this time, the limiting rod 3 no longer moves, and the movable shaft 2 maintains this height, which supports the tow truck.

[0028] The collar 13 is at least one set and is sleeved on the fixed shaft 4. The diameter of the limit rod 3 is larger than the diameter of the spring 5. The diameter of the spring 5 is larger than the diameter of the middle hole at the bottom of the movable shaft 2. The diameter of the fixed shaft 4 is adapted to the diameter of the middle hole. The outer wall diameter of the movable shaft 2 is adapted to the inner wall diameter of the support seat 1.

[0029] After the ring 13 is placed on the fixed shaft 4, the spring 5 is placed on the ring 13, and then the movable shaft 2 is placed vertically in the support seat 1 so that its bottom is placed on the fixed shaft 4. At this time, the spring 5 plays a role of elastic support for the movable shaft 2, and the position of the baffle 10 in the bottom plate 8 is adjusted to block the bottom of the limit rod 3, thereby positioning the height of the movable shaft 2.

[0030] The upper end of the support seat 1 is evenly surrounded by a downward extending slide groove, and the bottom of the support seat 1 is provided with an installation groove corresponding to the slide groove one by one, which is used to install the base plate 8; two lead screws 11 are rotatably arranged on each group of base plates 8 and are connected to the baffle 10 sliding in the base plate 8; a hinge seat is installed on the circumferential side of the movable shaft 2, and the hinge seat can slide along the slide groove at the upper end of the movable shaft 2, and at the same time can limit the freedom of lateral rotation of the movable shaft 2.

[0031] Before supporting the tow truck, the number of appropriate collars 13 can be selected according to the actual use environment, and the collars 13 are sleeved on the fixed shaft 4, and then the spring 5 is placed on the collar 13, and then the movable shaft 2 is placed in the support seat 1. At this time, the spring 5 is separated between the movable shaft 2 and the collar 13 to play a buffering role;

[0032] The bottom plate 8 is placed in the corresponding notch at the bottom of the support seat 1, and then the limiting shaft 9 is inserted to hinge the bottom plate 8 at the bottom of the support seat 1, and the limiting rod 3 and the movable shaft 2 are hingedly connected by the pin shaft 6, and then the first nut 7 is rotated and installed on the pin shaft 6 to limit the loosening of the pin shaft 6. At this time, the bottom of the limiting rod 3 abuts against the middle notch of the bottom plate 8. According to the height to be supported, the movable shaft 2 moves up or down in the support seat 1, and the bottom of the limiting rod 3 is at the middle notch of the bottom plate 8. After it moves to the appropriate position, the second nut 12 on the screw 11 can be rotated to make the second nut 12 abut against the end of the middle notch of the bottom plate 8, thereby limiting the movement of the baffle 10. At this time, the limiting rod 3 no longer moves, and the movable shaft 2 maintains this height, which supports the tow truck.

[0033] And because the bottom plate 8 is hinged to the bottom of the support seat 1, the device can be adaptively adjusted when the bottom surface is uneven or there is a slope. The corresponding set of baffles 10 on the bottom plate 8 can be moved to a suitable position to block the bottom of the corresponding limit rod 3, so that the support seat 1 can remain in a vertical state. At this time, there will be a certain gap between the bottom of the support seat 1 and the bottom surface, which can be filled with hard objects such as external bricks to stabilize the support seat 1, so as to support the tow truck.

[0034] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
