[0028] The surfaces of the connecting block 9302 and the abutting block 9305 are provided with limiting holes, which can be limited by cooperating with the clamping rod 9301. The sides of the fixed block 937 and the sliding block 938 that are away from each other are both set to be inclined, and the side of the clamping block 935 close to the fixed block 937 is set to be inclined. The cross section of the surface of the end of the abutting block 9305 close to the rocker 92 is an inclined surface.

[0029] When in use, the paraffin raw material is put into the feed port 2, guided by the guide plate 3, and the heating rod 5 is turned on to heat and melt it. The generated gas impurities enter the impurity removal box 6 through the conduit 7, and the gas impurity removal liquid in the impurity removal box 6 reacts with the gas impurities and is discharged through the exhaust hole. At this time, the pump body 1 86 and the pump body 2 800 are turned on, and the liquid wax enters the filter box 80 through the connecting pipe 88 and the bellows 87, is filtered through the filter plate 83, and is discharged through the Y-shaped tube 89.

When the slider 93 8 When the surface of the fixed block 937 contacts, the block 935 moves along the slider 938 and the fixed block 937, thereby releasing the limit. At this time, the locking rod 9301 disengages from the limiting holes of the connecting block 9302 and the contact block 9305. At this time, the rocker 92 can be rotated, and the rocker 92 drives the contact groove 930 to rotate. The contact groove 930 contacts the inclined surface of the contact block 9305, so that the contact block 9305 enters the linkage groove 9303. When the contact groove 930 and the contact block 9305 are parallel, the spring four 9304 drives the contact block 9305 to reset. When the rocker 92 rotates, the contact block 9305 enters the contact groove 930 in turn, which will not hinder the normal rotation of the rocker 92.

[0030] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
