The rotation of shaft 201b drives the moving bar 201a to move, and the movement of the moving bar 201a can drive the universal wheel 301b to move. The movement of the universal wheel 301b drives the rotating disk 301a to move. The movement of the rotating disk 301a drives the support plate 301c to move. When the rack 201d is moved, the connecting rod 202f will be driven to move up and down. The movement of the connecting rod 202f drives the racks 201d on both sides to move at the same time, so that the angle of the mounting frame can be adjusted.

[0042] Specifically, a handle 202g is provided at the bottom of the pulling shaft 202c, and there are two handles 202g, both of which are fixed at the bottom of the pulling shaft 202c. A limit block 202h is provided at the top of the pulling shaft 202c, and there are two limit blocks 202h, both of which are fixed at the top of the pulling shaft 202c.

[0043] By pulling the handle 202g, the pulling shaft 202c is driven to move, and the movement of the pulling shaft 202c drives the rack 201d to move. The pulling shaft 202c can only rotate on the inner wall of the rack 201d and cannot move up and down on the inner wall of the rack 201d. After the adjustment is completed, the rack 201d needs to be limited. First, the pulling shaft 202c is rotated. The rotation of the pulling shaft 202c drives the limit block 202h to rotate. The limit block 202h rotates to limit the rack 201d.

[0044] Specifically, a fixed frame 302a is provided on the top of the rotating disk 301a, and there are two fixed frames 302a, both of which are fixed on the top of the rotating disk 301a.

The rotating shaft 302b is movably connected with the moving bar 201a, and a fixing groove 302a-1 is opened on one side of the fixed frame 302a. There are two fixing grooves 302a-1, both of which are provided on one side of the fixed frame 302a.

[0045] By rotating the universal wheel 301b, the universal wheel 301b drives the rotating disk 301a, the rotating disk 301a drives the fixed frame 302a to rotate, and the fixed frame 302a drives the rotating shaft 302b to rotate, so that the universal wheel 301b can be rotated to adjust the angle.

[0046] Specifically, a fixed shaft 302c is disposed in the fixed frame 302a, and there are two fixed shafts 302c, both of which are plugged into the inner wall of the fixed frame 302a.

[0047] The fixed shaft 302c is used to support the fixed frame 302a.

[0048] Example 3

[0049] Reference Figure 5 and Figure 6 , which is the third embodiment of the utility model, and this embodiment is based on the first two embodiments.

[0050] Specifically, the outer sleeve of the fixed shaft 302c is provided with an extrusion block 302d, and there are two extrusion blocks 302d, both of which are inserted into the outside of the fixed shaft 302c, and the extrusion block 302d is movably connected to the fixed shaft 302c. A fixing plate 302e is provided at the bottom of the extrusion block 302d, and there are two fixing plates 302e, both of which are fixed to the inner wall of the fixed frame 302a.

[0051] When the universal wheel 301b needs to be limited after adjusting the angle, the extrusion block 302d is pressed, and the extrusion block 302d moves on the inner wall of the fixed groove 302a-1, and the extrusion block 302d is separated from the fixed groove 302a-1. At the same time, the extrusion block 302d will squeeze the fixed plate 302e, and the fixed plate 302e is squeezed to stick to one side of the universal wheel 301b to fix the universal wheel 301b, so that the universal wheel 301b can be limited, avoiding accidental sliding of the universal wheel 301b when it does not need to move, thereby reducing safety hazards.

[0052] Specifically, it also includes a main body component 100, which is arranged at one end of the fixed block 202a, including a support frame 101 and an electric hoist 102. The support frame 101 is fixed at one end of the fixed block 202a. The support frame 101 is provided with a limiting groove 101-1. There are multiple limiting grooves 101-1, all of which are arranged on one side of the support frame 101. The electric hoist 102 is arranged at the bottom of the support frame 101.

[0053] The support frame 101 is used to support the electric hoist 102, which is a device for lifting objects. The limit groove 101-1 is used to engage with the limit block 202h for limiting. When the rack 201d needs to be rotated, the handle 202g is rotated, and the handle 202g drives the pulling shaft 202c to rotate on the inner wall of the rack 201d. The rotation of the pulling shaft 202c drives the limit block 202h to engage with the limit groove 101-1, so that the rack 201d can be limited.

[0054] Specifically, an angle bracket 103 is fixed to the bottom of the support frame 101 .

[0055] The angle bracket 103 can strengthen the connection between the components of the support frame 101, making the entire structure more stable and able to withstand various forces brought by the operation of the electric hoist 102.

[0056] When in use, when the support frame 101 needs to be adjusted in angle, the handle 202g is pulled, and the handle 202g moves to pull the pulling shaft 202c, and the pulling shaft 202c drives the rack 201d to move, and the movement of the rack 201d drives the connecting rod 202f to move up and down, and the movement of the connecting rod 202f drives the racks 201d on both sides to move at the same time, and the rack 201d moves and meshes with the gear 201c, and when the pulling shaft 202c moves, it drives the rack 201d 1d squeezes the torsion spring 202e, the gear 201c rotates to drive the connecting shaft 201b to rotate, the connecting shaft 201b rotates to drive the moving bar 201a to move, after the adjustment is completed, the rack 201d needs to be limited, by rotating the handle 202g, the handle 202g drives the pulling shaft 202c to rotate on the inner wall of the rack 201d, the pulling shaft 202c rotates to drive the limiting block 202h to rotate, at this time the limiting block 202h is engaged with the limiting groove 101-1, so that The rack 201d is limited. When the moving bar 201a moves to the specified position, the universal wheel 301b needs to be limited. By pressing the extrusion block 302d, the extrusion block 302d is separated from the fixing groove 302a-1, and the extrusion block 302d will squeeze the fixing plate 302e. The fixing plate 302e is squeezed to fit against one side of the universal wheel 301b, so that the universal wheel 301b can be limited. When the universal wheel 301b needs to be released from the limit, the extrusion block 302d is pressed. The block 302d is moved to make the extrusion block 302d engage with the top of the fixed groove 302a-1, thereby driving the fixed plate 302e to separate from the universal wheel 301b. When it is necessary to release the limit of the rack 201d, the handle 202g is turned, and the handle 202g drives the limit block 202h at the top of the pulling shaft 202c to separate from the limit groove 101-1. At this time, the rack 201d returns to its original position through the rotation force of the torsion spring 202e, and the support frame 101 can be moved back and forth in this way.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
