Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: Reference Figures 1-4 An adjustable manual hoist support slide shown includes a main body 1. A clamping plate 6 is rotatably connected to the upper surface of the main body 1. A support shaft 4 is installed between the main body 1 and the clamping plate 6. A slide bar 9 is fixedly connected to the surface of one of the main bodies 1, and a U-shaped plate 20 is fixedly connected to the surface of the other main body 1. The inner wall of the U-shaped plate 20 is slidably connected to the surface of the slide bar 9. A positioning groove 15 is opened on the surface of the slide bar 9. The same positioning pin 16 is inserted into the inner wall of the U-shaped plate 20 and the inner wall of the positioning groove 15. A return spring 17 is sleeved on the surface of the positioning pin 16. One end of the return spring 17 is fixedly connected to the surface of the U-shaped plate 20, and the other end of the return spring 17 is fixedly connected to the surface of the positioning pin 16. A mounting positioning mechanism is provided on the opposite surfaces of the main body 1 and the clamping plate 6.

[0021] With the above structure, the clamping plate 6 cooperates with the main body 1 to achieve installation and fixation on the support shaft 4. The slide bar 9 slides with the U-shaped plate 20 to maintain the stability of the sliding adjustment between the pair of main bodies 1. The positioning pin 16 is inserted and fixed with the positioning groove 15 in the corresponding position to maintain the positioning stability between the pair of main bodies 1. The reset spring 17 keeps the installation of the positioning pin 16 stable and prevents it from slipping out of the positioning groove 15. The installation and positioning mechanism can adjust the distance between the pair of main bodies 1 and at the same time, the main body 1 can be removed from the support shaft 4 as a whole.

[0022] Preferably, the installation positioning mechanism includes a circular groove 21 formed on the opposite side of the main body 1 and the clamping plate 6. The surface of the main body 1 is provided with an installation groove 19. Multiple spring telescopic rods 14 are fixedly connected to the inner wall of the installation groove 19. One end of the multiple spring telescopic rods 14 is fixedly connected to an L-shaped plate 11. The top end of the L-shaped plate 11 is slidably connected to the lower surface of the clamping plate 6.

[0023] By setting a circular groove 21, the surface of the circular groove 21 is adapted to the surface of the support shaft 4 to allow space avoidance during installation. By setting multiple spring telescopic rods 14, the L-shaped plate 11 is driven to reset and is blocked and limited by the limiting block 13.

[0024] Preferably, a pair of limiting blocks 13 are fixedly connected to the inner wall of the mounting groove 19, the lower surface of the limiting blocks 13 is pressed into contact with the surface of the L-shaped plate 11, and a top rod 12 is fixedly connected to the surface of the L-shaped plate 11.

[0025] By setting the limit block 13, the L-shaped plate 11 is kept in a stable position. By setting the top rod 12, the operator can drive the L-shaped plate 11 to compress the spring telescopic rod 14.

[0026] Preferably, one end of the support shaft 4 is rotatably connected to a roller 3, and a guide slide 2 is installed between a pair of front and rear rollers 3, with multiple rollers 3 installed inside the guide slide 2.

[0027] By setting rollers 3, the support shaft 4 is driven to move on the guide slide 2, thereby changing the position of the main body 1.

[0028] Preferably, a first anti-detachment plate 5 is fixedly connected to the end of the support shaft 4 away from the roller 3, the circular groove 21 is adapted to the surface of the support shaft 4, the surface of the clamping plate 6 is provided with a toggle groove 10, and a second anti-detachment plate 18 is fixedly connected to one end of the slide bar 9.

[0029] By setting the first anti-slip plate 5, the main body 1 is prevented from slipping off the support shaft 4. By setting the actuation groove 10, the clamping plate 6 can be rotated under force through the actuation groove 10. The second anti-slip plate 18 of the same specification is set to prevent the second anti-slip plate 18 from detaching from the spiral plate 20.

[0030] Preferably, the inner wall of the clamping plate 6 is rolledly connected to a first ball head 7, and the inner wall of the main body 1 is rolledly connected to a second ball head 8. Both the first ball head 7 and the second ball head 8 are in contact with the surface of the guide slide 2.

[0031] By setting the first ball head 7 and the second ball head 8 to contact the surface of the guide slide 2, the stability of the main body 1 during overall movement is maintained, while reducing friction.

[0032] The working principle of this utility model is as follows: An adjustable manual hoist support slide, in use, the roller 3 drives the main body 1 to move as a whole. When it is necessary to adjust the distance between a pair of main bodies 1, after the positioning pin 16 is released from the insertion state in the positioning groove 15, the sliding adjustment strip 9 is slidably adjusted in the position of the loop plate 20. After the distance between a pair of main bodies 1 is adjusted, the positioning pin 16 is inserted into the corresponding position of the positioning groove 15 through the return spring 17 to keep the distance between the pair of main bodies 1 stable. When it is necessary to remove the main body 1 as a whole, push the top rod 12, and the compression spring telescopic rod 14 becomes shorter. At this time, the sliding L-shaped plate 11 releases its limiting state with the limiting block 13. By rotating the clamping plate 6 through the actuating groove 10, the contact between the clamping plate 6 and the surface of the support shaft 4 is released, and then the clamping plate 6 can be removed and replaced as a whole with the main body 1.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
