[0011] Furthermore, the pressing plate slides into the second limiting groove.

[0012] This utility model has the following beneficial effects:

[0013] This invention utilizes a fastening assembly. By pressing down on the pressing plate, the pressing plate moves the guide post and the round rod downwards. The round rod then moves the limiting plate and the arc-shaped groove downwards until the arc-shaped groove no longer contacts the ball bearing. The round rod is then inserted into the first sliding groove. Finally, the pressing plate is released, allowing the pressing plate and the ball bearing to return to their initial positions due to the spring's rebound force, until the outer wall of the ball bearing contacts the inner wall of the first limiting groove, thus achieving a fastening effect. This invention solves the problem that traditional screws and bolts require additional tools and more manual operation during installation, making the process relatively cumbersome and increasing the complexity of assembly.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-7 This utility model provides a technical solution: a fastener for installing plastic parts, including a first plastic plate 1 and a second plastic plate 2. The first plastic plate 1 has two first circular grooves 101, and a circular plate 301 is installed on the first circular grooves 101. The second plastic plate 2 has two second circular grooves 201, and a cylinder 304 is installed on the second circular grooves 201.

[0025] The fastening assembly 3 includes a circular plate 301, a cylinder 304, and a ball bearing 311. There are two circular plates 301 and two cylinders 304. The circular plate 301 has a first sliding groove 302 and a first limiting groove 303, which are connected. The cylinder 304 has a second sliding groove 305 and a second limiting groove 306, which are connected.

[0026] The cylinder 304 has four bead grooves 312. The ball 311 cooperates with the bead grooves 312. The bead grooves 312 are used to accommodate the ball 311, and the ball 311 will only move left and right in the bead grooves 312 and will not fall out.

[0027] When it is necessary to fasten the first plastic plate 1 and the second plastic plate 2, a guide post 307 is slidably fitted on the second slide groove 305. A pressing plate 313 is installed on the guide post 307. With a round rod 308 installed at the bottom of the guide post 307, the pressing plate 313 is pressed down, causing the pressing plate 313 to drive the guide post 307 and the round rod 308 to move downward. A limiting plate 309 is installed at the bottom of the round rod 308. The limiting plate 309 has four arc-shaped grooves 310. Two sets of balls 311 are provided, with four balls 311 in each set. When the balls 311 cooperate with the arc-shaped grooves 310, the round rod 308 drives the limiting plate 309 and the four arc-shaped grooves 310 to move downward until the arc-shaped grooves 310 no longer contact the balls 311, thereby causing the four balls 311 to gather inward.

[0028] With the cylinder 304 slidingly engaged in the first groove 302, the cylinder 304 is inserted downwards into the first groove 302 until the bottom of the second plastic plate 2 abuts against the surface of the first plastic plate 1. Finally, the pressing plate 313 is released. A spring 314 is installed on the pressing plate 313. The end of the spring 314 away from the pressing plate 313 is installed on the second limiting groove 306. With the spring 314 located outside the guide post 307, the pressing plate 313 returns to its initial position due to the rebound force of the spring 314. At the same time, the pressing plate 313 drives the guide post 307 and the round rod 308 to move upwards. The round rod 308 drives the limiting plate 309 and the arc groove 310 to move upwards. The arc groove 310 pushes the ball 311 outwards, causing the ball 311 to move in the ball groove 312 until the outer wall of the ball 311 abuts against the inner wall of the first limiting groove 303, achieving a fastening effect.

[0029] With the outer wall of the cylinder 304 abutting against the inner wall of the first groove 302, the cylinder 304 can move accurately along a predetermined path.

[0030] With the pressing plate 313 slidingly engaged with the second limiting groove 306 and the outer wall of the pressing plate 313 abutting against the inner wall of the second limiting groove 306, the second limiting groove 306 can make the pressing plate 313 slide up and down more stably.
