DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figure 1-Figure 6 , the utility model provides the following technical solutions:

[0032] Embodiment 1: By setting a lubricating assembly, the rod body 1 and the connecting rod 2 can be lubricated by lubricating oil when working, such as Figure 1-Figure 5 As shown:

[0033] It comprises a rod body 1, a connecting rod 2 is welded to the upper surface of the rod body 1, a connecting plate 3 is rotatably provided on the surface of the connecting rod 2, a material storage pipe 4 is fixedly connected to the end of the connecting plate 3, and a pipe cover 7 is threadedly connected to the surface of the material storage pipe 4;

[0034] Also includes:

[0035] A lubricating assembly is arranged on the lower surface of the storage tube 4, comprising a soft leather case 5 fixedly connected to the lower surface of the storage tube 4 and a spray head 6 fixedly connected to the lower surface of the soft leather case 5. When the lubricating assembly is working, lubricating oil can be sprayed onto the rod body 1 to facilitate the operation of the rod body 1. The long pin 16 is fixedly connected to the upper surface of the connecting plate 3;

[0036] The stabilizing component is arranged on the upper surface of the connecting disk 3, and includes a push rod 17 movably arranged inside the long pin 16 and a rubber block 18 fixedly connected to the end of the push rod 17. When the stabilizing component is working, it can increase the friction between the long pin 16 and the connecting disk 3 and the external device, so that the connecting disk 3 will not rotate when the rod body 1 is working.

[0037] A push rod 9 is fixedly connected to the surface of the connecting rod 2, a limiting rod 12 is fixedly connected to the inner wall of the connecting disk 3, and a fixing block 13 is slidably provided on the limiting rod 12, and a movable plate 10 is fixedly connected to the lower surface of the fixing block 13.

[0038] A squeezing rod 11 is fixedly connected to the side of the movable plate 10, and the squeezing rod 11 initially fits against the surface of the soft leather case 5, a first spring 14 that plays an elastic reset role is fixedly connected to the side of the fixed block 13, and the other side of the first spring 14 is fixedly connected to the inner wall of the connecting disk 3.

[0039] An auxiliary ball 15 is rotatably arranged inside the fixed block 13, and the surface of the auxiliary ball 15 fits with the surface of the limiting rod 12. The material storage tube 4 is symmetrically distributed about the center of the rod body 1. The material storage tube 4, the soft leather cover 5 and the movable plate 10 are all inclined, and the inclination angles of the material storage tube 4, the soft leather cover 5 and the movable plate 10 are the same.

[0040] When working, the rod body 1 is installed at the output end of the external driving device, and the rubber block 18 is pressed against the surface of the external driving device. When the rod body 1 rotates, it will drive the connecting rod 2 and the push rod 9 to rotate. When the push rod 9 rotates, it will intermittently contact with the movable plate 10. When the push rod 9 rotates to push the movable plate 10, the movable plate 10 will drive the fixed block 13 to squeeze the first spring 14 (the limit rod 12 makes the fixed block 13 move only in the horizontal direction). When the push rod 9 rotates to not contact with the movable plate 10, the movable plate 10 returns to its original position under the action of the first spring 14 and the fixed block 13, that is, the movable plate 10 and the extrusion rod 11 make reciprocating linear motion in the horizontal direction, and then the soft leather cover 5 will be intermittently pushed by the extrusion rod 11, so that the nozzle 6 intermittently sprays lubricating oil, which not only makes the rod body 1 work more smoothly, but also achieves the purpose of cooling. After long-term use, the pipe cover 7 can be opened to add materials to the storage pipe 4.

[0041] Embodiment 2: Different from Embodiment 1, the rod body 1 is prepared before working by setting the push rod 17 and the rubber block 18, such as Figure 1 and Figure 2 As shown:

[0042] The stabilizing assembly also includes a protrusion 19 fixedly connected to the left and right sides of the push rod 17, and a strong spring 20 that plays an elastic reset role is fixedly connected to the lower surface of the protrusion 19, and the other side of the strong spring 20 is fixedly connected to the inner wall of the long pin 16. The end of the push rod 17 is a protrusion, and the push rod 17 can also be connected to an external device by bolts.

[0043] During use, the rod body 1 is installed on the output end of the external drive, and the rubber block 18 is pressed against the surface of the external drive device, or the push rod 17 is fixed to the surface of the external drive device by bolts. When the rod body 1 and the connecting rod 2 are working, the long pin 16, the connecting plate 3, the storage tube 4 and the soft leather cover 5 will not move. At the same time, the strong spring 20 also allows the rubber block 18 to press against the surface of the external drive device, thereby improving stability.

[0044] Embodiment 3: Different from Embodiment 2, the ball 8 makes the connecting rod 2 rotate more smoothly. Figure 3 As shown:

[0045] A ball 8 is rotatably disposed inside the connecting plate 3 , and the ball 8 is also rotatably disposed inside the connecting rod 2 .

[0046] When the rod body 1 and the connecting rod 2 rotate, the ball 8 inside the connecting disk 3 reduces the friction between the connecting rod 2 and the connecting disk 3, so that the connecting rod 2 rotates more smoothly.

[0047] The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.

[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
