[0014] The utility model is further configured as follows: the diameters of the second limiting groove and the first limiting groove are the same as the diameter of the limiting rod.

[0015] By adopting the above technical solution, the limiting groove 1 and the limiting groove 2 are provided to be engaged with the limiting rod, and the limiting rod is inserted into the limiting groove 1 and the limiting groove 2 to limit the scraper.

[0016] In summary, the utility model has the following beneficial effects:

[0017] The utility model sets the limit of the connection plate by setting the elasticity of the spring, so that the limit rod of the connection plate is stuck in the inside of the limit groove 1 and the limit groove 2, and the scraper is limited to the left and right. The scraper is guided by the guide block and the guide groove to limit the front and back of the scraper, thereby ensuring the stability of the scraper when it is installed and used; and the spring can continuously limit the limit rod in the absence of tension, thereby ensuring that the limit rod will not separate from the limit groove 1 and the limit groove 2. When the connection plate is pulled by an external force, the connection plate pulls the spring to extend and drive the limit rod to separate from the limit groove 1, which is convenient for the user to slide and pull out the scraper, and also convenient for the user to slide and push the scraper into the inside of the knife seat. By loosening the connection plate, the extended spring rebounds and pulls the connection plate, so that the connection plate pushes the limit rod to be stuck in the corresponding limit groove 1 and the limit groove 2, eliminating the traditional screw fixing step, and facilitating the quick completion of the disassembly and assembly of the scraper.

[0022] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0023] Embodiment 1:

[0024] refer to Figure 1 , Figure 2 and Figure 3 A screen printing scraper device comprises a scraper seat 1, a scraper 2 is arranged inside the scraper seat 1, a guide block 3 is fixedly connected to the top and bottom of the inner cavity of the scraper seat 1, and a guide groove 4 which is slidably connected to the guide block 3 is provided on the top and bottom of the scraper 2; a connecting plate 5 is provided on the top of the scraper seat 1, and a plurality of limiting rods 6 are fixedly connected to the bottom of the connecting plate 5, a plurality of limiting grooves 7 are provided inside the scraper 2, a plurality of limiting grooves 8 are provided on the top and bottom of the scraper seat 1, and the surface of the limiting rod 6 is provided with a plurality of limiting grooves 7, and a plurality of limiting grooves 8 are provided on the top and bottom of the scraper seat 1. A spring 9 is provided in the sleeve; the connecting plate 5 is limited by setting the retractability of the spring 9, so that the limiting rod 6 of the connecting plate 5 is stuck in the limiting groove 1 7 and the limiting groove 2 8, and the scraper 2 is limited to the left and right. The scraper 2 is guided by the guide block 3 and the guide groove 4 to limit the scraper 2 front and back, thereby ensuring the stability of the scraper 2 when used after installation; and the spring 9 can continuously limit the limiting rod 6 in the absence of tension, thereby ensuring that the limiting rod 6 will not separate from the limiting groove 1 7 and the limiting groove 2 8. When the connecting plate 5 is pulled by an external force, the connecting plate 5 pulls the spring 9 to extend and drive the limit rod 6 and the limit groove 1 7 to separate, which is convenient for the user to slide and pull out the scraper 2, and also convenient for the user to slide the scraper 2 into the inside of the knife holder 1. By loosening the connecting plate 5, the extended spring 9 rebounds to pull the connecting plate 5, allowing the connecting plate 5 to push the limit rod 6 to be stuck into the corresponding limit groove 1 7 and limit groove 2 8, eliminating the traditional screw fixing step, and facilitating the quick completion of the disassembly and assembly of the scraper 2.

[0025] Furthermore, the top end of the spring 9 is fixedly connected to the connecting plate 5 via a spring fixing piece, the bottom end of the spring 9 is fixedly connected to the knife seat 1 via a spring fixing piece, and both ends of the spring 9 are fixedly connected to the connecting plate 5 and the knife seat 1 respectively. When the connecting plate 5 is pulled, under the limiting action of the fixed connection between the bottom end of the spring 9 and the knife seat 1, the spring 9 can only extend, and will not be separated from the knife seat 1.

[0026] Furthermore, the spring 9 is located at the top of the knife seat 1. The spring 9 has a rebound force after being extended. Through the setting of the spring 9, the spring 9 will extend and generate a rebound force when being pulled. When the spring 9 loses the pulling force, the rebound force of the spring 9 can allow the spring 9 to actively reset.

[0027] Furthermore, a pull rod 10 is fixedly connected to the top of the connecting plate 5. The pull rod 10 is located at the center of the top of the connecting plate 5. The setting of the pull rod 10 facilitates the user to pull the connecting plate 5, so that the connecting plate 5 drives the spring 9 to extend.

[0028] Furthermore, one side as well as the top and bottom of the scraper 2 are in contact with the inner wall of the blade holder 1, so that after the scraper 2 is inserted into the interior of the blade holder 1, it can fully adapt to the blade holder 1 without shaking.

[0029] Furthermore, the diameter of the limiting groove 2 8 and the limiting groove 1 7 is the same as the diameter of the limiting rod 6. Through the setting of the limiting groove 1 7 and the limiting groove 2 8, they are used to be engaged with the limiting rod 6. By inserting the limiting rod 6 into the limiting groove 1 7 and the limiting groove 2 8, the scraper 2 can be limited.

[0030] Brief description of the use process: During installation, pull the pull rod 10 upwards, so that the pull rod 10 drives the connecting plate 5 and several limiting rods 6 at the bottom of the connecting plate 5 to move upwards and separate the limiting groove 1 7 and the limiting groove 2 8. At the same time, the spring 9 will also extend and generate a rebound force due to being pulled by the connecting plate 5.

[0031] The user makes the guide grooves 4 at the top and bottom of the guide block 3 correspond to the guide block 3, and pushes it horizontally into the interior of the knife seat 1. After the scraper 2 is in place, the limit groove 1 7 inside the scraper 2 will correspond to the limit groove 2 8 at the top and bottom of the inner cavity of the knife seat 1, and then releases the connecting plate 5. At this time, the extended spring 9 resets and pulls the connecting plate 5 downward. When the connecting plate 5 moves downward, it pushes the spring 9 to reset. The spring 9 passes through the limit groove 2 8, limit groove 1 7, and limit groove 2 8 in turn. At this time, the scraper 2 will be limited. The spring 9 will not actively extend and push the connecting plate 5 to drive the limit rod 6 and the limit groove 1 7 to separate from the limit groove 2 8 without external force.

[0032] When in use, the scraper 2 scrapes the ink on the screen, and the force points are borne by the guide block 3 and the guide groove 4.

[0033] When removing the scraper 2, pull the pull rod 10 to drive the connecting plate 5 to move, and the connecting plate 5 drives the limiting rod 6 and the limiting groove 1 7 to separate from the limiting groove 2 8, and push the scraper 2 to one side and separate it from the blade holder 1 under the guidance of the guide block 3 and the guide groove 4.
