[0007] The beneficial effects of the utility model are as follows: the lever mechanism composed of the support rod assembly and the push rod assembly has a simple structure and is easy to process, and the fastener can be tilted upward with little effort, so that the fastener can be taken out conveniently.

[0008] To avoid pinching your hands when pressing down on the ejector assembly;

[0009] As a further improvement of the above technical solution: a safety seat is installed on the base below the main screw.

[0010] The beneficial effect of this improvement is that the safety seat plays a role in supporting the limit main screw, thereby preventing the operator's hands from being pinched by the main screw and the base when pressing down the main screw.

[0011] To prevent the safety seat and the main screw from pinching the operator's hands;

[0012] As a further improvement of the above technical solution: a safety nut is threadedly connected to the main screw, and when the surface of the main screw is connected to the top of the safety seat, the safety nut is located behind the safety seat.

[0013] The beneficial effect of this improvement is that the operator can hold the main screw behind the safety nut and press it down to avoid injury due to placing the hand between the main screw and the safety seat.

[0014] To facilitate the installation of fasteners;

[0015] As a further improvement of the above technical solution: the length between the head of the main screw and the limit nut is 5-50 mm greater than the length of the sleeve.

[0016] The beneficial effect of this improvement is that the operator can slide and move the position of the main screw to move the head end of the main screw to below the fastener or move it out from below the fastener, which is convenient for lifting out and installing the fastener.

[0017] In order to make the main screw be evenly stressed to lift the fastener;

[0018] As a further improvement of the above technical solution: the main screw and the transverse screw form a cross-shaped rod structure.

[0019] The beneficial effect of this improvement is that the support rod assembly and the top rod assembly cooperate to evenly load and tilt the fastener.

[0020] In order to facilitate the installation of the horizontal screw;

[0021] As a further improvement of the above technical solution: the transverse screw is a double-head screw structure, and the positioning nuts are arranged on both sides of the fixing nut.

[0022] The beneficial effect of this improvement is that the transverse screw can be conveniently inserted into the fixing nut and then quickly fixed by twisting the positioning nut.

[0023] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the protection scope of the present invention.

[0029] Embodiment 1:

[0030] like Figure 1—3 shows: a fastener pin removal tool, comprising a base 1, on which a cross fastener seat 2, a straight fastener seat 7 and a cross fastener seat pad 3 are installed, on which a support rod assembly 4 is arranged, and the support rod assembly 4 comprises a transverse screw 41, which is rotatably inserted on a fixing nut 31, which is welded on the cross fastener seat pad 3, and a positioning nut 42 is threadedly connected to the transverse screw 41, and the transverse screw 41 is welded to a top rod The push rod assembly 5 comprises a sleeve 51, in which a main screw 52 is inserted, and a limit nut 53 is threadedly connected to the main screw 52. The lever mechanism composed of the support rod assembly 4 and the push rod assembly 5 has a simple structure and is easy to process, and the fastener can be tilted upward with little effort, so as to facilitate the removal of the fastener. A safety seat 6 is installed on the base 1 below the main screw 52, ​​and the safety seat 6 plays the role of supporting and limiting the main screw 52, ​​so as to prevent the operator's hand from being hit by the main screw 52 and the limit nut 53 when pressing down the main screw 52. The base 1 is clamped, and the main screw 52 is threadedly connected with a safety nut 54. When the surface of the main screw 52 is connected with the top of the safety seat 6, the safety nut 54 is located behind the safety seat 6. The operator can hold the main screw 52 behind the safety nut 54 and press it down to avoid placing the hand between the main screw 52 and the safety seat 6 and getting injured. The length between the head of the main screw 52 and the limit nut 53 is greater than the length of the sleeve 51 by 5-50mm, and the operator can slide and move the main screw 52 to a certain position. The main screw 52 is positioned so that the head end of the main screw 52 moves to the bottom of the fastener or moves out from the bottom of the fastener, which is convenient for the fastener to be tilted out and installed. The main screw 52 and the transverse screw 41 form a cross-shaped rod structure. The support rod assembly 4 and the top rod assembly 5 cooperate to evenly lift the fastener. The transverse screw 41 is a double-headed screw structure. The positioning nuts 42 are arranged on both sides of the fixing nut 31. The transverse screw 41 can be easily inserted into the fixing nut 31, and then quickly fixed by twisting the positioning nuts 42.

[0031] The working principle of the present technical solution is as follows: fix the device as a whole under the bench drill, buckle the straight fastener on the seat body 71 and drop it into the groove of the card slot 72, insert a group of two cover plates of the cross or steering fastener and the intermediate body into the cross fastener seat 2, and the other side of the intermediate body is close to the cross fastener seat pad 3, operate the bench drill to push out the pin shaft, and then press down or knock the main screw 52 to make the main screw 52 rotate with the horizontal screw 41 as the support axis, and then make the end of the main screw 52 located under the fastener move up quickly to lift the fastener, and the safety seat 6 can play a limiting role to prevent the push rod assembly 5 and the base 1 from pinching the operator's hand.
