[0006] Preferably, a plurality of self-tapping screws penetrate through the rear side of the bearing pressing piece. The bearing pressing piece is fixedly connected to the inside of the base through the self-tapping screws. The number of the self-tapping screws is set to four.

[0007] Preferably, two screws penetrate through the rear side of the clutch. The clutch is fixedly connected to the rear side of the handle through the screws.

[0008] Preferably, a bottom cover is snap-connected to the rear side of the base. Two connecting pipes penetrate through the front side of the bearing pressing piece. The connecting pipes penetrate through the bottom cover.

[0009] Compared with the related art, the bearing clutch structure applicable to handle locks or ball locks provided by the present invention has the following beneficial effects:

[0010] Through the mutual cooperation of the bearing pressing piece, the bearing, the torsion spring and the clutch, and then through the installation and fixation of each structure by self-tapping screws and screws, the clearance between each component is controllable. Directly screwing for fixation increases the structural stability, has the advantages of improving the assembly efficiency, not having the phenomenon of jamming and no elasticity, and not having the phenomena of the handle becoming loose and sagging after long-term use, effectively increasing the service life.

[0020] Please refer to Figure 1-8 , the technical solution provided by the present invention specifically includes the following embodiments:

[0021] A bearing clutch structure applicable to a handle lock or a ball lock, comprising a handle 1 and a base 2, the handle 1 is installed on the front side of the handle 1, a bearing pressing piece 5 is fixedly connected inside the base 2, a bearing 3 is embedded inside the bearing pressing piece 5, a clutch 8 penetrates and is connected to the rear side of the bearing pressing piece 5, the bearing 3 is sleeved on the front part of the outer end of the clutch 8, and a torsion spring 7 is connected between the bearing pressing piece 5 and the clutch 8.

[0022] A plurality of self-tapping screws 6 penetrate and are connected to the rear side of the bearing pressing piece 5, the bearing pressing piece 5 is fixedly connected inside the base 2 through the self-tapping screws 6, the number of the self-tapping screws 6 is set to four, the self-tapping screws 6 can be used to fixedly install the bearing pressing piece 5 inside the base 2, the four self-tapping screws 6 are distributed in pairs, two on the left are distributed vertically, two on the right are distributed vertically, and the bearing pressing piece 5 is provided with holes for the self-tapping screws 6 to pass through.

[0023] Two screws 9 are connected through the rear side of the clutch 8, and the clutch 8 is fixedly connected to the rear side of the handle 1 through the screws 9. The clutch 8 and the handle 1 can be fixed together through the screws 9 so that the two can rotate synchronously.

[0024] The rear side of the base 2 is clamped with a bottom cover 10, and the front side of the bearing pressure plate 5 is penetrated by two connecting tubes 4, and the connecting tubes 4 penetrate the bottom cover 10. The bottom cover 10 can block the rear side of the base 2. At the same time, a plurality of adapter holes are opened on the bottom cover 10, so as not to affect the extension and installation and fixation of various structures.

[0025] A screw seat 51 is integrally formed and connected to the left and right sides of the rear side of the bearing pressing plate 5, and the hole on the bearing pressing plate 5 also penetrates the screw seat 51. At the same time, the part of the bearing pressing plate 5 located at the screw seat 51 is also provided with a hole for the connecting pipe 4 to pass through. The front end of the connecting pipe 4 has a hexagonal block, and the front side of the bearing pressing plate 5 is located at the part where the connecting pipe 4 passes through the hole. A hexagonal groove is also provided, so that when the connecting pipe 4 passes through the hole, the hexagonal block is embedded in the hexagonal groove to achieve limiting, and it will not rotate at will. At the same time, a stopper 52 is integrally formed and connected to the upper and lower sides of the rear side of the bearing pressing plate 5;

[0026] The base 2 is integrally formed with positioning ribs and screw holes that match the shape of the bearing pressing plate 5, and the self-tapping screws 6 are screwed into the screw holes to fix the bearing pressing plate 5;

[0027] The front side of the clutch 8 is integrally connected with a stopper 81 at the upper and lower sides. The two ends of the torsion spring 7 are in a relaxed state. Figure 7 and Figure 8 The position relationship shown is that the two ends of the torsion spring 7 are located on the sides away from each other of the adjacent screw seats 51 and the stopper one 52, and at the same time, one end of the torsion spring 7 is also located on the side of one of the stoppers two 81. The two stoppers two 81 are respectively located on the sides where the two stoppers one 52 are close to each other, and do not interfere with each other. When the handle 1 is rotated, the clutch 8 rotates accordingly, and the torsion spring 7 is twisted through the stopper two 81 to generate elastic force, which can be used to drive the clutch 8 and the handle 1 to rotate back to their original positions.

[0028] Working principle:

[0029] When the handle 1 is turned, the clutch 8 rotates accordingly, during which one end of the torsion spring 7 will be pushed by an 81 on the clutch 8 to generate elastic force. When the handle 1 stops turning, the elastic force of the torsion spring 7 will push the clutch 8 back to its original position, so that the handle 1 is lifted up again. When the clutch 8 is rotating, the clutch 8 and the bearing pressure plate 5 are movably connected through the bearing 3, so that the handle 1 can rotate smoothly when it is turned and lifted.
