The locking plate is provided with multiple pressure rollers, one end of which is hinged to a base plate on one side of the iron shaft, and the other end is rotatably mounted with a movable clamping plate. The support column is fixed to the base plate on the other side of the iron shaft, and a clamping block is provided on the side of the support column away from the iron shaft. The movable clamping plate is provided with a groove that matches the clamping block. When the groove of the movable clamping plate is engaged with the clamping block, the multiple pressure rollers are pressed against the iron shaft.

[0006] Preferably, the lower end of the movable card plate is provided with a guide slope corresponding to the card block.

[0007] Preferably, the upper end of the movable plate is connected to the free end of the locking plate by a tension spring.

[0008] Preferably, the back of the locking plate is provided with a limiting rod for limiting the movement of the movable plate. The limiting rod is arranged perpendicularly to the locking plate and is located below the rotating shaft of the movable plate. When the locking plate is in the open state, the movable plate is in the stretched state under the limitation of the limiting rod. When the locking plate is closed, the guide slope of the movable plate contacts the locking block first.

[0009] Preferably, the pressure roller and the support roller are located on the same vertical plane.

[0010] Preferably, there are two pressure rollers.

[0011] Preferably, it also includes a column located on the hinge side of the locking plate, the lower end of the column is fixed to the base plate, and a horizontal connecting plate is provided on the column; a magnet is fixed on the connecting plate, and when the locking plate is in the open state, it is attracted to the magnet.

[0012] Compared with the prior art, this utility model has the following advantages:

[0013] This device has a simple structure, is easy to operate, and is highly practical. After locking the locking plate, the two pressure rollers can prevent the iron shaft from jumping, making the iron shaft rotate more stably, thereby avoiding the problem of the iron shaft falling off.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example 1

[0021] Reference Figure 1-2 As shown, a locking device for a guide iron shaft 4 includes a locking plate 5 and a support column 8. The locking plate 5 is provided with two pressure rollers 6, one end of which is hinged to the base plate 1 on one side of the iron shaft 4, and the other end is rotatably mounted with a movable clamping plate 7. The support column 8 is fixed to the base plate 1 on the other side of the iron shaft 4, and a clamping block 9 is provided on the side of the support column 8 away from the iron shaft 4. The movable clamping plate 7 is provided with a groove 701 that matches the clamping block 9. When the groove 701 of the movable clamping plate 7 is engaged with the clamping block 9, both pressure rollers 6 are pressed onto the iron shaft 4.

[0022] More specifically, the pressure roller 6 and the support roller 2 are located on the same vertical plane.

[0023] In use, manually close the locking plate 5, and then snap the slot 701 of the movable plate 7 onto the locking block 9. At this time, both pressure rollers 6 are in contact with the iron shaft 4. When the iron shaft 4 rotates, the two pressure rollers 6 can prevent the iron shaft 4 from jumping, making the rotation of the iron shaft 4 more stable, thereby avoiding the problem of the iron shaft 4 falling off. Example 2

[0024] As a preferred embodiment of this utility model, this embodiment adds a tension spring 10, a limiting rod 11, and a magnet 13 to the first embodiment, specifically:

[0025] Reference Figure 3-5 As shown, the lower end of the movable plate 7 is provided with a guide slope 702 corresponding to the locking block 9, and its upper end is connected to the free end of the locking plate 5 by a tension spring 10. The back of the locking plate 5 is provided with a limiting rod 11 for limiting the movable plate 7. The limiting rod 11 is set perpendicular to the locking plate 5 and is located below the rotating shaft of the movable plate 7. When the locking plate 5 is in the open state, the movable plate 7 is in the stretched state under the limitation of the limiting rod 11; when the locking plate 5 is closed, the guide slope 702 of the movable plate 7 first contacts the locking block 9.

[0026] In use, manually close the locking plate 5. The guide slope 702 of the movable locking plate 7 first contacts the locking block 9. The locking block 9 pushes the movable locking plate 7 outward through the guide slope 702 until the locking groove 701 of the movable locking plate 7 is engaged with the locking block 9. To open, manually rotate the movable locking plate 7 clockwise to disengage its locking groove 701 from the locking block 9, and finally flip the locking plate 5 upward.

[0027] In this embodiment, by adding a tension spring 10, a limiting rod 11, and a guide slope 702, the slot 701 of the movable card plate 7 is automatically engaged with the card block 9, simplifying the operation steps.

[0028] In addition, the device also includes a column 3 located on the hinge side of the locking plate 5. The lower end of the column 3 is fixed on the base plate 1. A horizontal connecting plate 12 is provided on the column 3. A magnet 13 is fixed on the connecting plate 12. When the locking plate 5 is in the open state, it is attracted to the magnet 13. The setting of the magnet 13 can prevent the locking plate 5 from affecting the hoisting of the iron shaft 4.

[0029] In summary, this device has a simple structure, is easy to operate, and is highly practical. After locking the locking plate 5, the two pressure rollers 6 can prevent the iron shaft 4 from jumping, making the rotation of the iron shaft 4 more stable, thereby avoiding the problem of the iron shaft 4 falling off.

[0030] This utility model is not limited to the above-described embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this utility model, and the changed content still falls within the protection scope of this utility model.
