[0002] A pin is a pin that has one end that is cylindrical and the other end that is conical, similar to the shape of a bullet. It is mainly used to fix several separate objects together or to serve as a support for one object to be suspended on another object.

[0003] After the pin fixes the target part, it is usually flush with the target part, which leads to a lack of fulcrum when removing the pin. When the pin needs to be taken out, it is necessary to use multiple tools specially used for pulling out the pin to pull out the pin, which is cumbersome and very troublesome. Utility Model Content

[0008] A return spring, one end of which is fixedly mounted on the inner wall of the slide slot, and the other end of which is fixedly mounted on the outer wall of the limit plate. The return spring is arranged in cooperation with the limit plate so that the pull rod and the pull block can be pushed outward from the pin.

[0009] Preferably, the pull block is provided with an auxiliary mechanism, which enables the staff to pull out the pins better. The auxiliary mechanism comprises a rotating shaft, which is rotatably connected to the inner wall of the pull block.

[0010] Preferably, a handle is fixedly mounted on the outer wall of the rotating shaft, and the provision of the handle makes it convenient for the staff to apply a greater pulling force, thereby facilitating the pulling out of the pin.

[0011] Preferably, a torsion spring is provided at the connection between the rotating shaft and the pulling block, and the rotating shaft can be driven to rotate and reset by providing the torsion spring.

DETAILED DESCRIPTION

[0025] like Figure 1-Figure 7 As shown, the utility model provides a technical solution: a pin structure that is easy to pull out, including a pin 1, an inner wall of the pin 1 is provided with a slide groove 2, and the slide groove 2 can make the pull rod 41 slide out to the outside of the pin 1, and the inner wall of the pin 1 is provided with a circular groove 3, and the turntable 42 can be rotated by setting the circular groove 3. The interior of the pin 1 is provided with a nail pulling mechanism 4 that is convenient for pulling out the nail, and the installation of the pin 1 can be conveniently pulled out without the aid of tools by setting the nail pulling mechanism 4.

[0026] The nail pulling mechanism 4 includes a pull rod 41, a rotating disk 42, a reset spring 43, a limit plate 44, a pull block 45, a protruding strip 46, a groove 47, a spring spring 48, and a rubber block 49; the pull rod 41 is slidably connected to the inner wall of the slide groove 2, and one end of the pull rod 41 is fixedly installed with a limit plate 44. By setting the limit plate 44, the pull rod 41 can be prevented from sliding out of the slide groove 2. The other end of the pull rod 41 is fixedly installed with a pull block 45. When the pull rod 41 and the pull block 45 protrude from the pin 1, the pull block 45 is pulled to cooperate with the pull rod 41 The limit plate 44 can apply a pulling force to the pin 1, so that the installed pin 1 can be easily pulled out without the help of tools. The outer wall of the pull block 45 fits the inner wall of the circular groove 3. The outer wall of the limit plate 44 is fixedly installed with a rubber block 49. The friction between the staff's hand and the turntable 42 can be increased by setting the rubber block 49, so that the staff can better rotate the turntable 42. The outer wall diameter of the limit plate 44 is larger than the outer wall diameter of the pull rod 41. The limit plate 44 fits in the slide groove 2 The inner wall of the pull rod 41 is fixedly installed with a convex strip 46, the top of the convex strip 46 is attached to the bottom of the turntable 42, the turntable 42 is rotatably connected to the inner wall of the circular groove 3, and a groove 47 is provided on the turntable 42. The inner diameter of the groove 47 is the same as the outer diameter of the convex strip 46. The turntable 42 is rotated to rotate on the inner wall of the circular groove 3 and compress the spring 48. At the same time, the turntable 42 will drive the groove 47 to rotate synchronously. When the groove 47 rotates to coincide with the convex strip 46, the turntable 42 will be disengaged. For limiting the convex strip 46, a clockwork spring 48 is fixedly installed on the outer wall of the turntable 42. The side of the clockwork spring 48 away from the turntable 42 is fixedly installed on the inner wall of the circular groove 3. One end of the reset spring 43 is fixedly installed on the inner wall of the slide groove 2, and the other end of the reset spring 43 is fixedly installed on the outer wall of the limit plate 44. When the convex strip 46 coincides with the groove 47, the limit plate 44 can be pushed upward by the elasticity of the reset spring 43, so that the pull rod 41 drives the convex strip 46 to slide outward in contact with the inner wall of the groove 47.

[0027] The pull block 45 is provided with an auxiliary mechanism 5, which enables the staff to pull out the pin 1 better. The auxiliary mechanism 5 includes a rotating shaft 51, a handle 52, and a torsion spring 53; the rotating shaft 51 is rotatably connected to the inner wall of the pull block 45, and the outer wall of the rotating shaft 51 is fixedly installed with a handle 52. Pulling the handle 52 drives the rotating shaft 51 to rotate and squeeze the torsion spring 53, so that the handle 52 is expanded to the outside of the pull block 45. At this time, the two groups of handles 52 can enable the staff to hold it better, which is convenient for the staff to apply greater pulling force. The connection between the rotating shaft 51 and the pull block 45 is provided with a torsion spring 53. The elasticity of the torsion spring 53 can drive the rotating shaft 51 to rotate and reset, so that the rotating shaft 51 drives the handle 52 to rotate and enter the inner wall of the pull block 45.

[0028] Working principle: when it is necessary to pull out the installed pin 1, first rotate the turntable 42 to make the turntable 42 rotate on the inner wall of the circular groove 3 and compress the spring 48. At the same time, the turntable 42 will drive the groove 47 to rotate synchronously. When the groove 47 rotates to coincide with the convex strip 46, the turntable 42 will be free from the limit of the convex strip 46. At this time, the elasticity of the reset spring 43 can push the limit plate 44 upward, so that the limit plate 44 drives the pull rod 41 and the pull block 45 to slide outward of the pin 1, so that the pull rod 41 and the pull block 45 protrude from the pin 1. At the same time, the pull rod 41 will drive the convex strip 46 to slide outward in contact with the inner wall of the groove 47. The protruding pull block 45 can be used as a fulcrum. At this time, pulling the pull block 45, in cooperation with the pull rod 41 and the limit plate 44, can apply tension to the pin 1, thereby The installed pin 1 can be pulled out without the help of tools, which makes it more convenient to use. The protruding pull block 45 is pressed toward the inside of the pin 1, so that the pull block 45 drives the pull rod 41 to enter the inside of the slide groove 2, and makes the pull block 45 fit into the inside of the circular groove 3. At the same time, the pull rod 41 will drive the convex strip 46 to fit the inner wall of the groove 47 and slide toward the inside of the pin 1. When the convex strip 46 moves toward the inside of the pin 1 and disengages from the groove 47, the groove 47 disengages from the limit of the convex strip 46, and then the elasticity of the clockwork spring 48 can drive the turntable 42 to rotate and reset, so that the turntable 42 can drive the groove 47 to stagger with the convex strip 46. At this time, the convex strip 46 can be limited by the turntable 42, so that the pull rod 41 is fixed in the inside of the slide groove 2, and the use of the pin 1 is not affected.

[0029] When it is difficult to pull out the pin 1 by pulling the block 45, the handle 52 is pulled so that the handle 52 drives the rotating shaft 51 to rotate and squeezes the torsion spring 53, so that the handle 52 is expanded to the outside of the pull block 45. At this time, the two sets of handles 52 can enable the staff to hold it better, making it convenient for the staff to apply greater pulling force, thereby facilitating the pulling out of the pin 1.

[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.
