DETAILED DESCRIPTION

[0017] 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.

[0018] See also Figure 1-4The utility model provides a technical solution: it includes a mounting head 1, a connecting rod 2 and a fixed frame 3 fixed on a CNC machine tool, a pair of clamping claws 11 are rotatably connected in the mounting head 1, a clamping spring 12 is fixed between the clamping claws 11, the connecting rod 2 is fixed to the rear side of the mounting head 1, fixed side plates 31 are fixed at the four corners of the bottom of the fixed frame 3, bolt holes are provided on the fixed side plates 31, an adapting hole 32 is opened in the fixed frame 3, the connecting rod 2 passes through the adapting hole 32, a card block 4 is slidably connected to the upper side of the front end of the fixed frame 3, a positioning groove 21 is opened on the connecting rod 2 and aligned with the card block 4, the bottom of the card block 4 is inserted in the positioning groove 21, and protective blocks 13 are fixed on both sides of the mounting head 1.

[0019] A lifting plate 41 is slidably connected to the front end of the fixed frame 3 and the position corresponding to the card block 4. A pair of telescopic grooves 42 are opened on the front side of the fixed frame 3. A telescopic block 43 is slidably connected in the telescopic groove 42. A fixing spring 44 is fixed between the telescopic block 43 and the bottom of the telescopic groove 42. The front end of the telescopic block 43 is fixed on the lifting plate 41, and the card block 4 is fixed to the bottom of the lifting plate 41. A guide rod is fixed in the telescopic groove 42. The guide rod passes through the telescopic block 43 and is slidably connected to the telescopic block 43. A limit block 33 is fixed at the center position of the upper end of the adapter hole 32. A guide groove 22 is opened at the upper end of the connecting rod 2 and the position corresponding to the limit block 33. The size of the connecting rod 2 is consistent with the diameter of the adapter hole 32, and the thickness of the card block 4 is adapted to the width of the positioning groove 21.

[0020] Working principle: First, use bolts to fix the fixing frame 3 on the CNC machine tool. When installing the puller, you only need to insert the connecting rod 2 into the adapter hole 32. At this time, you need to lift the lifting plate 41. After the positioning groove 21 is aligned with the card block 4, the lifting plate 41 can be driven downward by the pull of the fixing spring 44, and finally the card block 4 can be driven downward and inserted into the positioning groove 21 to fix the position of the connecting rod 2. At the same time, when inserting the connecting rod 2, it is necessary to align the limit block 33 and the guide groove 22 so that The limit block 33 is inserted into the guide groove 22, which can effectively prevent the connecting rod 2 from rotating and deflecting. At the same time, after the limit block 33 abuts against the inner wall of the guide groove 22, the insertion depth of the connecting rod 2 can be positioned to ensure that the position of the clamping block 4 is aligned with the positioning groove 21. At the same time, when the puller is in use or stored, the protection block 13 can be used to limit the opening range of the clamping jaws 11 to avoid excessive pulling on the clamping spring 12, effectively protecting the clamping spring 12 and ensuring that there is sufficient holding force when clamping materials of matching sizes.
