An intermediate plate 6 is arranged between the left tool bit 2 and the right tool bit 3, and the endless belt 5 is sheathed outside the intermediate plate 6. The left tool bit 2 and the right tool bit 3 are equipped with first driving mechanisms 20, respectively. By the ?rst driving mechanisms 20, the left tool bit 2 is moved toward a left side face of the intermediate plate 6 and the right tool bit 3 is moved toward a right side face of the intermediate plate 6. The first driving mechanisms 20 are air cylinders, and the rollers 4 of the conveyor belt component are driven by a conveyor belt motor 41. The housing at least includes a press plate 13 located on an upper side of the endless belt 5. A space for ng a shell 81 of the electronic component 8 to pass therethrough is formed between the press plate 13 and an end face of the endless belt 5.

The front roller of the conveyor belt component is located outside the housing, the endless belt 5 is partially exposed outside the housing to form a loading end, and the end of the endless belt 5 located in the housing is an uploading end, so that a workpiece collection box can be placed on the support plate, or the rear side of the housing can also be opened to m manual ing by workers. A through groove 15 g through the support plate from upper and lower sides is formed in a portion of the support plate 1 below the left tool bit 2 and the right tool bit 3, and a waste collection box is arranged on a lower side of the through groove.

The conveyor belt component is fixed on the upper side of the lifting plate 7, and the lifting plate 7 is equipped with a second driving mechanism. By the second g mechanism, the conveyor belt component is moved up and down relative to the intermediate plate 6. The second driving mechanism includes a driving motor 71 and a lead screw 72. The lead screw 72 is rotated to move the lifting plate 7 up or down. A threaded block 73 is fixed on the lifting plate 7, and the threaded block 73 is in thread fit with the lead screw 72. A number of guide blocks 74 are arranged on the lifting plate 7, a number of guide columns 75 are ed on the support plate 7, and guide holes matched with the guide columns 75 are formed on both the lifting plate 7 and the guide blocks 74.

Two left and right al plates 11 arranged in parallel are arranged on the support plate 1, and each of the ?rst g mechanisms 20 is ?xed to one of the vertical plates 11. A transverse plate 12 arranged in a left- right direction is ?xed on the left vertical plate. An upper end face of the transverse plate 12 is recessed to form a fixation groove g through the transverse plate from front and rear sides.
